The large number of restaurants and restaurants that provide Kaledo menus raises problems, namely the lack of utilization of beef bones from Kaledo waste, causing environmental issues. The community does not know much about the types of minerals contained in the beef bones. Among them are the minerals contained in beef bones, namely phosphorus and magnesium. This study aims to determine the levels of phosphorus and magnesium in beef bones from Kaledo waste taken randomly from Kaledo restaurants in Palu City. Determination of phosphorus and magnesium levels in beef bones from Kaledo waste using a Uv-Vis spectrophotometer and an atomic absorption spectrophotometer (AAS). The results showed that the analysis of the phosphorus content of beef bones from Kaledo waste 125 mg / 100 g, and the magnesium content was 102. 9 mg / 100 g. The results of this study are expected to be a source of information about the levels of phosphorus and magnesium contained in beef bones from Kaledo waste and can be used further as a substance in the utilization of beef bones from Kaledo waste. Keywords: Beef bones, calcium, phosphorus, and magnesium pepper, salt, and lime. The main strength of kaledo soup delicacy lies in the taste and freshness of beef meat and bones, which are the main constituent ingredients, in addition to the sour and spicy taste, in just the right proportions, which completes the final impression of the true kaledo taste (Mufida. Bone is a waste that can be used as a biomaterial to absorb metals in wastewater, because bones have many pores and contain tricalcium phosphate with a small part of calcium carbonate, which has the potential as an adsorbent (Yadav et , 2. The bones of beefs are, in principle, the same as those of any other animal. Has almost the same content, namely in adult beef bones contain 20 % water, 45 % ash, and 35% organic In 45 % ash, there is 37 % Ca and 18. % phosphate (Keene et al. , 2004. Gibson et al. Phosphorus is one of the elements of bone formation because it is needed in the process of bone mineralization. Low serum phosphate levels will limit bone formation and bone mineralization However, there is little evidence to show that foods with low phosphorus content affect the incidence of low BMD, as well as foods high in Introduction Indonesia is the largest archipelagic country in the world, located in Southeast Asia. Kalimantan. Java. Sulawesi. Sumatra, and Papua are the main islands in Indonesia. Apart from being the largest archipelago in the world. Indonesia has 34 provinces with various specialties, both from tribes and cultures, to culinary specialties from each province in Indonesia, one of which is the province of Central Sulawesi. Central Sulawesi has 12 regencies with various tribes and one capital city, namely the city of Palu, with a typical tribe, the Kaili tribe (Satyawati, 2. The Kaili tribe is a tribe with a very distinctive and famous culinary heritage in Indonesia, especially in Central Sulawesi. Among them are duo sale, uta kelo, corn rice, palumara, lalampa, labia dange, and the most famous in Central Sulawesi by the Kaili tribe, namely kaledo . onggala lembuh fee.

Serna & Bergwitz, 2. Magnesium is the fourth most abundant cation in the body and the second most abundant cation in the intracellular environment after Magnesium (M. has an important role in the structure and function of the human body. The adult human body contains approximately 25 grams of magnesium. Total magnesium in the body of an adult male is estimated to be 1 mole . (Haruda et al. , 2. Magnesium is indispensable in the body, especially involved in over 300 essential metabolic reactions. It is necessary for energy metabolism, glucose use, protein synthesis, fatty acid synthesis and breakdown, muscle contraction, all ATPase functions, almost all hormonal reactions, and maintaining cellular ionic balance (PelczyEska et , 2. Beef bones from Kaledo waste have nutritional and mineral content that is good enough for the growth period of toddlers, adolescents, adults, the elderly, and pregnant women. Beef bones from kaledo waste have a low water content which indicates that beef bones from kaledo waste can last for a long time or have good shelf life, the amount of beef bone water content from kaledo waste is 59 % and ash content is 61. 74 % which indicates that beef bones from kaledo waste have good mineral content for consumption by children, adolescents, adults, the elderly, and also pregnant Beef bones from Kaledo waste have calcium levels of 19. 68 mg / g. This shows that beef bones from Kaledo waste have high calcium levels in meeting calcium needs for the body in stunting prevention (Satyawati, 2. The purpose of this study was to determine the levels of Phosphorus (P) and Magnesium (M. in beef bones from Kaledo waste. Sampling is carried out specifically, namely on the part of the beef bone that has previously been processed into food with a heating process of about 4-6 hours.

Results and Discussion Result The results obtained from the analysis of phosphorus (P) and magnesium (M. levels in beef bones from Kaledo waste using the Uv-vis method and atomic absorption spectrophotometry (AAS) are presented in the following table: Nurzaida Isnawiyah et al. from Kaledo waste. Kaledo is a food made from beef bones that contains bone marrow, fat, pieces of leg bones, and small pieces of beef and cartilage processed with beef leg bones. Bone-based kaledo, in addition to containing fatty acids and vitamins, also contains micronutrients such as iron (F. and calcium (C. in the bone marrow (Mufida, 2. The sample used in the analysis of phosphorus and magnesium levels is beef bone powder from kaledo waste, which has been determined by water content and ash content, namely, beef bone powder from kaledo waste that has been through the sample preparation and ovening stages and has also been used. Based on Satyawati . , the water content in beef bones from kaledo waste is 4. 59 %, and the water content 74 %. It is stated that the water content in beef bones from kaledo waste is small, and the ash content in beef bones from kaledo waste is a lot, which means the character and shelf life of a good food for a long time, and a lot of mineral content in beef bones from kaledo waste. Samples of beef bones from Kaledo waste that have been opened later, dissolved with HNO3 1 M with pH = 1, then diluted twice, namely from a 10 mL measuring flask to 50 mL, which is then diluted in a 100 mL measuring flask, so that a dilution factor of 10 times is obtained. The 1 M HNO3 used in the trailer preparation serves to dissolve the metals present in the sample, as concentrated HNO3 is a universal metal solvent and can stabilize the metals to be analyzed. The addition of concentrated HNO3 in the ashing process aims to oxidize all carbon and dissolve the salts contained in the sample. The process of analyzing phosphorus and magnesium levels is diluted again when they are analyzed, namely, diluting the sample from 10 mL to a 100 mL measuring flask. Furthermore, the dilution factor at the digestion is multiplied by the dilution factor when analyzing phosphorus levels in beef bone samples from Kaledo waste, until a total of 10 times the dilution factor is obtained. Mineral concentration measurements are made with uv-vis spectrophotometers and atomic absorption spectrophotometers, and the measured snapshot must be a solution. The mineral content in a sample is calculated based on the total weight of beef bone material from Kaledo waste. So that from the results of the study showed an average phosphorus level of 9. 512 mg / 100 g and an average magnesium level of 102. 9 mg / 100 g.

Average Table 2 shows the average levels of magnesium contained in beef bones from Kaledo In the results of calculations that have been carried out, it was found that magnesium levels for beef bones from Kaledo waste amounted to 1. mg / g. Discussion This study began with sample preparation, or sample preparation carried out to produce beef bone meal from kaledo waste, with the weight of wet beef bone samples used after cleaning as much as 400 grams. After drying, a dry sample weight of 35 grams was obtained. Powdered beef bones are obtained as much as 300 grams. The sample used in the study was 80 grams for analysis of phosphorus and magnesium levels in beef bones from Kaledo waste. Analysis of phosphorus and magnesium levels in beef bones from Kaledo waste Phosphorus (P) Analysis of phosphorus levels by the UV-Vis spectrophotometry method using molybdate precipitation and magnesium level analysis was carried out by the atomic absorption spectrophotometry method. Both mineral content analyses aim to analyze phosphorus and magnesium levels of beef bones from Kaledo waste. In addition, this study is intended to provide further information related to the substance in the use of beef bones In Table 1 of beef bones from Kaledo waste, it was found that each treatment had a difference that was not much different. Treatment in the analysis of phosphorus levels is carried out by three repetitions . to get more accurate results. The results of the analysis of phosphorus levels obtained from each repetition were 9. 525 mg / 100 g, 95 mg / 100 g, and 9. 512 mg / 100 g. Phosphorus levels in each repetition had a slight difference in Volume, 13. No. 1, 2024, 25-31 Jurnal Akademika Kimia yield because the difference was not much. Phosphorus has very important biochemical and physiological roles and is the most abundant mineral in the body after calcium. About 80 Ae 85 % is present in bone, and 15 Ae 20 % is in soft tissue and fluid (Ciosek et al. , 2. In bone. P is stored in the form of calcium hydroxyapatite. Ca10(PO. 6(OH)2, and plays an important role in the process of bone Changes in bone composition and structure due to P loss are as important as Ca Phosphorus is also a phospholipid component that affects cell permeability, a constituent component of myelin, energy metabolism . denosine triphosphat. , part of genetic material, acid-base regulation, and enzymatic activity (Torres et al. , 2. The function and metabolism of phosphorus (P) of this element are found as calcium phosphate salts in the hard tissues of the body, namely bones and teeth, giving hard properties to both types of tissues (Hong et al. , 2. Phosphorus minerals, 80% present in hard tissues and 20% present in soft tissues, mainly as phosphoric acid clusters. P levels in the body are about 8% of body weight. Phosphorus is found in hard tissues at lower levels than other minerals, such as calcium (C. , but in soft tissues, the phosphorus (P) portion is higher than Many mechanisms of energy transport processes are attributed to phosphate bonds, such as ATP and ADP, keratin phosphate, and phosphoenol pyruvate. Various metabolites that hold important functions contain phosphates, and the metabolism of many nutrients begins with phosphorylation, usually with the participation of ATP (Paath et al. , 2014. Nicholls et al. , 2. In addition to playing a role in bone mineralization, phosphorus, as an organic phosphate, plays an important role in reactions related to the storage or release of energy in the form of Adenine Triphosphate (ATP) (Michigami & Ozono, 2. The oxidation of metabolic fuels is controlled by the availability of ADP, which is further controlled by the rate at which ATP is used for physical activity and metabolism (Alghannam et , 2. Phosphorus participates in the activation of several reactions in all metabolism. According to Satyawati . , the analysis of calcium levels in beef bones from Kaledo waste. The average level of calcium (C. contained in beef bones from Kaledo waste is 19. 68 mg / g. This shows that beef bones from Kaledo waste have high calcium levels in meeting calcium needs for the body in stunting prevention. Calcium and phosphorus are very important in the process of bone mineralization. a deficiency of these two minerals or an improper ratio can affect bone There is a balanced ratio between calcium and phosphorus that can help calcium absorption, the body will maintain a ratio of calcium: phosphorus 2: 1 or 1: 1, a ratio that is vital for ideal bone growth because inorganic phosphate has many roles in biological processes such as cell metabolism, cell markers, as coenzymes, nucleotide metabolism, energy metabolism, membrane function, and bone mineralization. Magnesium (M. In Table 2, the results obtained from each repetition are 102 mg / 100 g, 103. 6 mg / 100 g, and 103 mg / 100 g. The magnesium level in each repetition has a slight difference in results because the difference is not much. Magnesium has an important role in various processes that affect growth. This element is one that is needed by living things for their metabolic The results of the study showed that magnesium levels in beef bones from Kaledo waste have a large amount. This can help the role of magnesium in the growth process of living things. Based on similar research that the mineral content in bone samples from Kaledo waste is quite large (Haruda et al. , 2. , hydroxyapatite is synthesized from beef bones and phosphoric acid using precipitation methods. Hydroxyapatite is synthesized from bovine bones, which are a source of calcium. Calcium from beef bones comes from calcium oxide (CaO) compounds obtained from the calcination process of beef bones at a temperature of 1000 AC for 6 hours. Calcined beef bones have a weight change from 4 Kg to 2. 483 Kg. This change 07 %. Changes in weight and color of beef bones during the calcination process are caused by the decomposition process of organic substances and water loss in beef bones (Hart et al. , 2. Kaledo . onggala ox foo. is one of the famous culinary specialties in Central Sulawesi. The number of restaurants that provide kaledo menus causes problems because of the lack of utilization of bone waste, which causes problems in the People still do not know that beef bones still contain protein. Protein serves as a builder of new tissue during the growth and development of the body. This study aims to determine the protein content of beef bones from kaledo waste from the city of Palu. Central Sulawesi, which was taken randomly from a kaledo restaurantAidetermination of protein content in beef bones from kaledo waste using the Kjeldahl In the calculation results that have been carried out with three repeats, the protein content in Deuteronomy 1 is 3. 85 %. Repetition 2 is 3. 59 %, and Replay 3 is 4. 2 %. The average protein content of beef bones from Kaledo waste is 3. 88 %. The results of this study are expected to be a source of information about the protein content contained in beef bones from kaledo waste and can be further used as material in the utilization of bone waste (Anisa, 2. Beef bones from Kaledo waste have a mineral content that is good enough for growth. Table 3 shows the difference in levels of several mineral contents found in beef bones from Kaledo waste, where beef bones from Kaledo waste have calcium levels of 19. 68 mg / g.
