Pacitan Regency, holds several distinctive features. In addition to being known as a Auvillage of learningAy due to the presence of a centuries-old Islamic boarding school . Tremas is also popularly recognized as the birthplace of IndonesiaAos sixth president. Susilo Bambang Yudhoyono. Tremas is situated approximately 11 kilometers north of PacitanAos regency center (Herlianto A, 2. JNUS: Journal of Nahdlatul Ulama Studies. Vol. 6 No. The name AuTremasAy is said to derive from two words: trem, from patrem meaning a weapon or small keris, and mas, meaning gold, a precious metal commonly used for womenAos jewelry. This etymology is closely connected to a story about the clearing of a forest that later became known as Tremas. The first person to clear the forest was a court officer from Surakarta named Ketok Jenggot, acting on the kingAos orders as a reward for his services in safeguarding the palace from danger (Wiyonggo Seto, 2. Mbah Ketok Jenggot and K. Abdul Manan Dipomenggolo, although coming from different backgrounds and periods, succeeded in combining spiritual and social power in disseminating Islamic teachings in Tremas. Mbah Ketok Jenggot, whose birth name was Raden Bagus Sudarmaji, served as an officer of the Surakarta Hadiningrat Palace (Rojihan. Known as the pioneer . abat ala. of Tremas Village in Arjosari. Pacitan. East Java, he is popularly described as possessing extraordinary spiritual prowess, including the legend that his long beard could not be cut by any weapon (Al Ahmadi, 2. Ki Ketok Jenggot was considered no ordinary person. He was credited with suppressing the rebellion of Adipati Bantheng Wereng against the kingdom. After Bantheng WerengAos defeat. Ki Ketok Jenggot (Ki Bagus Sudarmadj. reported his success to the King in Surakarta and was granted tanah perdikan . ax-exempt lan. north of Semanten Village, with the task of clearing the forest in that area (Herlianto A, 2. It is also noted that prior to Ketok JenggotAos forest clearing, a group had already settled in the area, including Raden Ngabehi Honggowijoyo (K. Abdul MananAos father-in-la. After seeking permission and explaining his mission. Ketok Jenggot proceeded to clear much of the forest. Upon completion, the patrem emas he carried was said to have been planted at the spot where he first began the clearing. the newly opened area was then named AuTremasAy (Wiyonggo Seto, 2. AuMbah Ketok Jenggot started it. Then the early roots of Pesantren Tremas emerged through Raden Dipomenggolo. While studying at Tegalsari. Ponorogo. Raden Dipomenggolo was a fellow struggler with Prince Diponegoro,Ay stated K. Fuad Habib Dimyathi during the groundbreaking ceremony for a madrasah building on Saturday . /01/2. (Muhdhori Ahmad, 2. The history of Pesantren Tremas is closely intertwined with the formation of Pacitan and Tremas and with local religious developments. In the fifteenth century CE, the archipelago was under Majapahit rule, and much of the population adhered to HinduBuddhist traditions, including in southern Wengker (Pacita.

Raden Ngabehi Dipomenggolo is recognized as the founder . uAoassi. of Pesantren Tremas, established in the early nineteenth century . His major role in laying the foundations for Islamic propagation through pesantren education earned him recognition as a pioneer and one of the early initiators of other pesantren in the archipelago, which expanded rapidly from the late nineteenth to early twentieth centuries (Ahmad Muhammad. As a teenager, he was sent by his father to Tegalsari Pesantren in Ponorogo to study Islamic knowledge under Kiai Hasan Besari. During his time there. Bagus Darso studied diligently and consistently. due to his persistence, discipline, and intelligence, his mastery of religious sciences reportedly surpassed many of his peers. After being considered sufficiently trained, he returned to Semanten (Anwar Sanusi, 2. Upon returning from his educational journey, he established a pesantren in Semanten . pproximately one kilometer north of Pacitan cit. On the basis of familial considerations, distance from political centers and crowds, and a more conducive learning environment for students, he later relocated to Tremas (Muhammad Imron, 2. Abdul Manan is described as laying the first foundations of Pesantren Tremas after completing his studies at Tegalsari. His initial step was building a mosque. As students from Semanten and other regions began to arrive, a simple dormitory was built south of the mosque, constructed from bamboo and thatch. Funding for the early construction came from his father-in-law. Demang Tremas Raden Ngabehi Honggowijoyo . relative within the Dipomenggolo family lin. Abdul Manan Dipomenggolo was known as a scholar with deep religious knowledge who attracted followers through a daAowah approach characterized by warmth and He is also recognized as one of the pioneers of the wider Nusantara scholarly network, as subsequent generations traced from his lineage most notably Shaykh Mahfudz al-Tarmasi produced prominent students such as K. Hasyim AsyAoari. Wahab Hasbullah, and K. Bisri Syansuri, who later founded Nahdlatul Ulama in 1926 (Faizin and Mahbib, 2. This study is situated within pesantren scholarship, which is not a new research Earlier studies have examined the role of local religious figures in the history of JNUS: Journal of Nahdlatul Ulama Studies. Vol. 6 No. Islamization in Indonesia, including the role of kiai within pesantren and Islamic educational centers in Java. Other works highlight daAowah strategies that foreground local values in engaging diverse communities. By undertaking this research, the study not only recognizes the uniqueness and cultural value of these figures, but also contributes to sustaining cultural, social, and economic continuity in Tremas Village. The study is expected to generate synergy between tradition and modernity and to provide deeper understanding of the roles of spiritual figures in local society. Previous research on Pesantren Tremas includes WijayantiAos . undergraduate thesis on collective leadership in policy decision-making at Perguruan Islam Pondok Tremas, which emphasized the institutionAos vision, mission, and educational foundations . incerity, simplicity, freedom, self-reliance, mutual help, and ukhuwah diniya. Historical discussion in that study was limited to a brief institutional profile. Another relevant work is MahmudahAos . thesis on the salafiyah education system as a source of competitive advantage at Perguruan Islam Pondok Tremas, focusing on how Tremas maintains salafiyah education in the modern era. Both works discuss leadership dynamics across different periods, yet neither specifically examines K. Abdul MananAos daAowah struggles in detail. they provide only brief The key difference between the two studies lies in their focus: educational foundations versus the sustainability of salafiyah education. Based on the above, this study formulates the following research questions: How does cultural daAowah through acculturation, indigenization, and cultural mediation explain the roles and legitimacy of local figures (Mbah Ketok Jenggot and K. Abdul Mana. in building acceptance of Islam in Tremas? And how does the pesantren as an educational daAowah institution through religious habitus formation, cadre development, and scholarly networks explain K. Abdul MananAos strategies in sustainably institutionalizing Islam in Tremas? Research Method This research employs a qualitative descriptive approach. According to Creswell . , qualitative research uses textual and visual materials to analyze data creatively through various inquiry strategies. Qualitative research aims to obtain a holistic understanding of a phenomenon from the perspective of the people studied. It deals with ideas, perceptions, opinions, and beliefs that cannot be measured numerically (Moleong, 2. Data sources The Role of NU Figures in Cultural DaAowah. (Afra. Fadhilah. Fajriyanto. Riza. include the documentary text Manuskrip Tremas by Ahmad Muhammad and key informants who serve as the hamlet head and Tremas site caretaker. The data consist of words and sentences from the manuscript and interview notes relating to Mbah Ketok Jenggot as the land-clearing pioneer of Tremas. Data collection was conducted through document observation and systematic note-taking, as well as interviews. The note-taking technique is an advanced procedure used in conjunction with observational methods, including participant and non-participant observation approaches, whereby relevant data from texts are recorded (Firdhayanti, 2. Interviews are conversations conducted with a particular purpose between an interviewer and an interviewee (Moleong, 2. The collected data were classified according to analytical needs and examined using an interactive analysis model. Miles and HubermanAos . interactive model consists of three concurrent flows: data reduction, data display, and conclusion drawing/verification. Cultural DaAowah Theory: Acculturation. Indigenization, and Cultural Mediation Cultural daAowah is an approach that places culture as the primary medium for communicating Islamic values through symbols, language, rituals, arts, and social relations. In the anthropology of religion, religion does not exist in a vacuum. it is always AuarticulatedAy through local meaning systems already embedded in society. Accordingly, cultural daAowah may be understood as a communicative strategy that aligns normative religious messages with local cultural structures so that acceptance becomes persuasive and sustainable (Geertz. Koentjaraningrat, 1. Within the framework of acculturation, religious change occurs through mutual penetration of cultural elements in which Islamic values enter social life without necessarily severing all existing cultural expressions. This theory emphasizes that religious transformation is typically gradual and selective: certain local elements are retained as social expressions, while others are reinterpreted to align with new religious norms. In the Javanese Islamic context, historical scholarship shows that Islamization often proceeds through complex syntheses and adjustments between normative teachings and local practices (Ricklefs, 2006. Woodward, 1. The concept of indigenization . of Islam argues that AulocalityAy is not a threat to religion, but rather a space of social expression so long as it does not contradict core religious principles. Theoretically, indigenization can be read as an effort to make Islam present as an embodied social ethic rather than merely a formal identity by recognizing local JNUS: Journal of Nahdlatul Ulama Studies. Vol. 6 No. cultural forms as pedagogical, cultural, and social vehicles. This framework helps position daAowah as a value negotiation process that is sensitive to context without losing normative orientation (Wahid, 2001. Hefner, 2. Sociologically, cultural daAowah can also be explained through cultural mediation theory: religious messages become effective when mediated by symbols and authorities recognized by the community. In such mediation, symbolic language . arratives, myths, rituals, and tradition. functions as a cognitive-affective bridge that reduces distance between religious teachings and peopleAos lived social experience. Cultural daAowah thus operates not only through the transmission of knowledge, but also through the formation of collective meaning, identity, and social solidarity (Geertz, 1960. Hefner, 2. Pesantren as an Educational DaAowah Institution: Habitus. Cadre Reproduction, and Scholarly Networks The pesantren can be theorized as a socio-religious institution that performs daAowah through education, moral formation, and the production of religious leadership. Within pesantren traditions, daAowah is not limited to preaching or teaching sessions. it is realized through structured learning systems and strong pedagogical relations between kiai and santri, supported by the authority of classical Islamic texts. Therefore, pesantren may be positioned as a center for reproducing Islamic tradition that maintains continuity of values, practices, and religious authority at the community level (Dhofier, 1994. Steenbrink, 1. From the perspective of practice theory, pesantren produces religious habitus durable dispositions formed through repeated routines of worship, social discipline, etiquette, and learning culture. Habitus makes religiosity not merely normative knowledge but a way of life that regulates daily social action. In this framework, pesantren education functions as an effective mechanism of value internalization because it integrates cognitive, affective, and practical dimensions within a single social ecosystem (Bourdieu, 1990. Dhofier, 1. Pesantren may also be explained as a community of practice in which religious competence develops through gradual participation moving from peripheral to central involvement . egitimate peripheral participatio. This theory emphasizes that learning occurs through meaningful engagement in social activities rather than mere content transfer. pesantren contexts, intellectual apprenticeship . dab, discipline, and the social role of the santr. becomes a core element of education and daAowah because it forms religious identity through collective experience (Lave and Wenger, 1991. Steenbrink, 1. The Role of NU Figures in Cultural DaAowah. (Afra. Fadhilah. Fajriyanto. Riza. Finally, pesantren operates within scholarly networks and intellectual mobility that extend its authority beyond local boundaries. Network theories of knowledge explain how chains of transmission . , teacherAestudent relations, and text circulation generate legitimacy and standardize religious knowledge. Thus, pesantren is not merely a local institution but a node within a broader Islamic intellectual ecology that produces cadres of scholars and strengthens transmission of religious tradition across regions and generations (Azra, 2004. van Bruinessen, 1. Findings and Discussion The Process of Land Clearing in Tremas by Mbah Ketok Jenggot Tremas Village was established by a figure named Ki Bagus Sudarmadji, an officer of the Surakarta Hadiningrat Palace originating from Semanten. Pacitan. He was said to have an extraordinarily long beard that could not be cut by any weapon. For this reason, the early origins of Tremas are popularly associated with the epithet AuKetok Jenggot. Ay Based on an interview with the Tremas village head. Mbah Ketok Jenggot cleared land north of Semanten under the King of SurakartaAos orders. The interview excerpt states: AuKi Ketok Jenggot was not an ordinary person. He played a major role in suppressing the rebellion of Adipati Bantheng Wereng against the kingdom. His birth name was Raden Bagus Sudarmaji, but due to his extraordinary powers he was called Ki Ketok Jenggot. After Bantheng WerengAos defeat. Ki Ketok Jenggot (Ki Bagus Sudarmadj. reported to the King in Surakarta. He was granted tax-exempt land north of Semanten and instructed to clear the forest in that area. However, the year in which he cleared the Tremas forest remains disputed to this day. Ay (CLHW 01/NK) This interview indicates that Mbah Ketok Jenggot (Raden Bagus Sudarmaj. was credited with suppressing Bantheng WerengAos rebellion. After reporting his success to the King, he received tanah perdikan north of Semanten and was tasked with clearing the forest in that region. Yet, the precise timing of the Tremas clearing remains contested. Another interview with a local resident suggests that Mbah Ketok Jenggot was widely believed to possess extraordinary spiritual power: AuMbah Ketok Jenggot was known for his supernatural prowess. even his long beard was said to be impervious to weapons. It is said that he cleared haunted forests by offering a sacrifice in the form of a small golden keris, which later inspired the name AoTremas. Ao The heirloom was planted in the ground in Krajan Hamlet, the same area as the Nahdatul Umam prayer house, located on land endowed by IndonesiaAos sixth president. Susilo Bambang Yudhoyono (SBY).

He is said to have died by musno disappearing bodily and the area is now known as Kulak Hamlet. Tremas Village. Local people believe his grave lies north of Pesantren Tremas. Pacitan. However, stories about his beard and other powers remain unverified and lack concrete evidence. Ay (CLHW 02/Q) This account presents Mbah Ketok Jenggot as the figure believed to have cleared AuhauntedAy forests in Tremas, associated with a golden keris as a symbolic AuofferingAy linked to the villageAos name. The narrative also connects the symbolism to Krajan Hamlet and the Nahdatul Umam prayer house. However, the informant simultaneously acknowledges the lack of verifiable evidence for these supernatural claims. DaAowah Strategies Employed by K. Abdul Manan in Disseminating Islam in Tremas Born Bagus Darso, the son of the Semanten village head. Raden Ngabehi Dipomenggolo is described as the founder . uAoassi. of Pesantren Tremas, established in the early nineteenth century . In promoting Islam, he employed several strategies. The study identifies four pieces of data on K. Abdul MananAos daAowah strategies from Manuskrip Tremas, as described below. DaAowah Strategy Through Establishing a Pesantren Data . AuHis major role as the founder of Islamic propagation through education . made him worthy of recognition as a pioneer and one of the initiators of other pesantren in the archipelago, which began to emerge from the late nineteenth to early twentieth centuries. Ay This indicates that K. Abdul MananAos primary daAowah strategy was establishing a He laid the foundations for Islamic dissemination through education, positioning himself as a key pioneer in pesantren development. His contribution extended beyond building a single institution. it opened pathways for the later proliferation of pesantren, making pesantren-based education a critical foundation for Indonesian Muslims. Data . AuHis decision to move to Tremas, his father-in-lawAos residence located eight kilometers to the north, was considered strategic and far more conducive, given that Tremas already had a stronger intellectual tradition. Although it required considerable time since he still managed the pesantren in Semanten this did not hinder him due to The Role of NU Figures in Cultural DaAowah. (Afra. Fadhilah. Fajriyanto. Riza. strong moral support from both his parents and his in-laws during the process of establishing the pesantren in Tremas. Ay This suggests that relocating to Tremas was a strategic choice. Tremas was considered more conducive and already possessed an intellectual tradition, facilitating pesantren growth. Despite continued responsibilities in Semanten, the availability of strong familial support sustained the pesantren-building process in Tremas. Data . AuEntering the 1840s, seeing the pesantren continue to grow and the situation as sufficiently safe and relatively stable. Kiai Abdul Manan began to think about the future of his pesantren. He felt the need to learn more as provision for managing a pesantren that was developing significantly. Ay This illustrates a reflexive strategy: as the pesantren expanded and conditions stabilized. Abdul Manan sought further learning to meet increasingly complex institutional demands. Continuous learning becomes part of an adaptive leadership approach for sustaining educational daAowah. DaAowah Strategy Through Initiating Religious Study Circles (Pengajia. Data . AuAfter establishing religious study circles in the Semanten village mosque for some time, in 1830 Kiai Abdul Manan moved to Tremas for several reasons: He became the son-in-law of Ngabehi Honggowijoyo, who served as demang. Honggowijoyo was related to Dipomenggolo. Recent findings indicate his wife was Nyai Andawiyah, granddaughter of Kiai Nuriman Mlangi, also known as BPH Sandiyo/KGPH Haryo Kartosuro, the elder brother of PB II and HB I. Tremas at the time was a prosperous area, with fertile rice fields and reportedly many valuable objects such as gold, which supported the development of a pesantren. Tremas was the only area in Pacitan whose population still adhered to Hindu-Siwa, also known as Javanese Hinduism. Thus. Tremas was considered a highly appropriate location for the daAowah of the young scholar Abdul Manan. With a daAowah approach adapted to local conditions, gradually but surely, the people of Tremas became Muslims and practiced Islamic teachings well. Ay This indicates that K. Abdul MananAos daAowah strategy involved expanding mosquebased pengajian and relocating to Tremas due to kinship networks, socio-economic potential. JNUS: Journal of Nahdlatul Ulama Studies. Vol. 6 No. and the religious composition of the population. By adapting daAowah to local social conditions. Islamization is presented as a gradual and persuasive process culminating in widespread Islamic adherence. Analysis of Cultural DaAowah: Acculturation. Indigenization, and Cultural Mediation in the Formation of Local Islam From the perspective of cultural daAowah, daAowah success is not determined solely by the Aucontent of the message,Ay but by the capacity of daAowah to operate within local meaning In anthropological terms, religion is always AuarticulatedAy through symbols and practices already understood by society. thus, effective daAowah typically does not begin by totally severing tradition, but by reading cultural structures that serve as references for collective identity (Geertz, 1960. Koentjaraningrat, 1. In this context, narratives of land clearing, place naming, and founding figures function as symbolic resources linking social change to perceptions of AuappropriatenessAy and AuacceptabilityAy within the community. The acculturation framework explains that religious transformation unfolds through gradual and selective encounters between religious values and local socio-cultural practices. Local elements that serve social cohesion tend to be maintained, while their meanings are reinterpreted to align with new religious norms (Ricklefs, 2006. Woodward, 1. Within this studyAos data, babat alas narratives and the Augolden patremAy symbol can be read as cultural devices organizing collective memory and social boundaries. as Islam enters, such devices do not necessarily disappear but can become AubridgesAy of acceptance because the community already recognizes them as references for origins and legitimacy. The concept of indigenization . emphasizes that Islam can become an embodied social ethic when its expression can utilize local media without losing normative Indigenization does not mean arbitrarily AuIslamizingAy culture. rather, it recognizes culture as a space of expression that can serve as a vehicle for value education, as long as it does not contradict core religious principles (Wahid, 2001. Hefner, 2. In this study, daAowah that Auadapts to community conditionsAy reflects the logic of indigenization: daAowah proceeds by considering economic conditions, social structures, and local religious orientations, producing a more stable and non-coercive transformation. Cultural mediation further explains why local figures become crucial. Cultural mediation occurs when religious messages become effective because they are mediated by recognized authority and accessible symbols. narratives, myths, and traditions operate as The Role of NU Figures in Cultural DaAowah. (Afra. Fadhilah. Fajriyanto. Riza. cognitive-affective bridges reducing distance between normative teachings and lived experience (Geertz, 1960. Hefner, 2. Here, the roles of figures . ncluding pioneers/founders and religious scholar. can be interpreted as providers of Auchannels of legitimacyAy: they do not merely communicate doctrine, but organize social meaning so that Islam is accepted as part of collective identity rather than as an external element. Analysis of Pesantren as an Educational DaAowah Institution: Religious Habitus. Cadre Formation, and Scholarly Networks In theories of the pesantren as an educational daAowah institution, establishing educational structures . osqueAestudy circlesAedormitoriesAepesantre. is understood as a daAowah strategy oriented toward long-term sustainability. Pesantren operates through formal and informal education that forms religious authority, maintains tradition, and systematically reproduces religious values and practices (Dhofier, 1994. Steenbrink, 1. DaAowah through pesantren therefore is not merely communication, but institutionalization: Islamic teachings become a living social system through routines, regulations, and community leadership. From practice theory, pesantren forms religious habitus dispositions embedded through repetition of worship practices, social discipline, etiquette, and consistent learning Habitus makes religion present as a Auway of lifeAy that directs social action rather than knowledge that is merely known but not practiced (Bourdieu, 1990. Dhofier, 1. Thus, when the data show mosque construction as an initial step followed by a simple dormitory and growing numbers of students, this sequence can be read as habitus formation: worship spaces and living spaces establish daily rhythms that normalize Islamic practice. Pesantren can also be analyzed as a community of practice where religious identity forms through gradual participation: individuals learn not only from texts but from engagement in meaningful social practice and strong pedagogical relations (Lave and Wenger. This framework clarifies why pengajian, boarding, and close kiaiAesantri relations become effective daAowah mechanisms: learning occurs through Ausocial apprenticeship,Ay where students emulate etiquette, internalize discipline, and inhabit religious social roles through collective experience, rather than through episodic preaching alone (Steenbrink, 1986. Dhofier, 1. Finally, scholarly network theory emphasizes that pesantren is not an isolated local unit, but a node within broader intellectual circulation. TeacherAestudent networks, scholarly mobility, and the transmission of intellectual authority strengthen pesantren legitimacy and JNUS: Journal of Nahdlatul Ulama Studies. Vol. 6 No. enable the expansion of influence across generations (Azra, 2004. van Bruinessen, 1. Through pesantren-based daAowah . cholars/educator. that extends daAowah reach: Islam not only AuentersAy a community but is reproduced into enduring scholarly traditions and religious leadership. Conclusion Based on the findings. IslamAos acceptance in Tremas can be understood as the result of cultural daAowah operating through acculturation and cultural mediation. Mbah Ketok Jenggot appears as a babat alas figure who carried socio-symbolic authority through origin narratives, territorial opening, and the AuTremasAy symbol . he golden patre. These narratives functioned as a Aucultural languageAy readily intelligible to the community, thereby producing early legitimacy, social space, and collective identity through which Islamic values could be introduced gradually. Subsequently. Abdul Manan developed daAowah aligned with the local socio-religious context . ncluding a population not yet fully Islamize. , enabling Islamization to proceed persuasively and sustainably. this corresponds to indigenization principles that treat culture as a daAowah medium as long as it does not conflict with Islamic The study further shows that K. Abdul MananAos central strategy was to institutionalize daAowah through pesantren development beginning with the mosque and pengajian, followed by dormitories and educational expansion. From pesantren theory, this strategy is effective because pesantren functions as a center for reproducing religious values and practices, ensuring that Islam does not stop at identity acceptance but becomes a stabilized pattern of life. Pengajian activities, student boarding, and learning environments cultivated a religious habitus . orship discipline, etiquette, and routin. that normalized Islamic practice in everyday life. Moreover, pesantren encouraged cadre formation through kiaiAesantri relations and scholarly traditions, and extended influence through wider scholarly networks that sustain knowledge transmission across generations. Therefore. Abdul MananAos strategy can be characterized as long-term educational daAowah: building institutions, shaping religious character, and preparing generational religious authority. The study recommends that local pesantren/NU leaders document and teach Tremas local narratives . rigins, babat alas, symbols, and site. as educational media so that tradition does not remain mere folklore but becomes a means for internalizing moderate and contextual Islamic values. It also recommends mapping living cultural practices in the community distinguishing which are socio-cultural . o be preserve. , which require reinterpretation, and which should be The Role of NU Figures in Cultural DaAowah.
