INTRODUCTION
Nationally, fisheries cultivation has an estimated potential of 15.
59 million hectares: 2.
million hectares in freshwater, 1.
22 million hectares in brackish water, and 12.
44 million hectares in the sea.
One of the commodities with the highest market demand is tilapia.
Tilapia (Oreochromis niloticu.
has thick flesh and a delicious flavor, making it highly sought after by the public to meet animal protein needs (Indriati & Hafiludin, 2.
Ikan Tilapia (Oreochromis niloticu.
is a commodity that can tolerate and adapt to various levels of salinity.
To increase tilapia production, a transformation into saline tilapia has been implemented.
Saline tilapia can be cultivated in brackish and marine waters at salinities up to 20 ppt.
Furthermore, saline tilapia grows quickly, can survive both low and high temperatures, and is resistant to disease (Angriani et al.
, 2.
One way to increase tilapia production is by understanding how to raise them to increase their growth rate.
Water quality and feed management are crucial, as these significantly impact tilapia survival.
Therefore, alternative supplements based on biodegradable, environmentally friendly, and abundant plants are needed.
One plant that can be used as a supplement is turmeric (Nurfaidah et al.
, 2.
According to Wahyuningtyas et al.
, turmeric contains several chemical compounds, including fructose, glucose, protein, essential oils, and curcumin, along with its derivatives, desmethoxycurcumin and bidesmethoxycurcumin, at 50-60%.
Curcumin can improve the digestion of proteins, fats, and carbohydrates, thus increasing nutrient absorption.
This is because curcumin stimulates the gallbladder wall to release bile into the small intestine.
The essential oils in turmeric help accelerate gastric emptying, increasing fish feed An empty stomach sends signals to the brain to increase fish feeding behavior (Santika et al.
, 2.
The results of research conducted by Nurfaidah et al.
, .
namely the use of turmeric at a concentration of 75% provided an optimum effect on the survival and growth of tilapia.
This can be seen from the specific weight growth rate of "2.

Furthermore, another study conducted by Santika et al.
on turmeric extract treatment in white snapper showed a significant effect on absolute growth.

The most effective dose of turmeric extract for white snapper growth was 20 ml.
Based on the above research, it was found that administering turmeric extract contributes to the growth of both freshwater and saltwater fish.
Therefore, this study was conducted on "The Effect of Turmeric Extract (Curcuma longa lin.

One of the problems often experienced by saline tilapia fish farmers is the relatively slow growth rate of seeds, which requires a longer cultivation time.
Therefore, this study was formulated to examine the effect of administering turmeric extract (Curcuma longa Linn.
) on the growth rate of saline tilapia fish (Oreochromis niloticu.
seeds and to determine the dose of turmeric extract that provides the most optimal effect.
The purpose of this study was to determine the effect of administering turmeric extract on the growth rate of saline tilapia fish seeds and to determine the best dose that can increase optimal growth.
The benefits of this study are expected to provide information and references for fish farmers and the general public regarding the use of turmeric extract as a feed additive, as well as serve as study material and references for further research.

5 grams per fry obtained from BLUPPB Karawang.
The research materials included saline tilapia fry, turmeric as the main extract ingredient, ethanol as a solvent, and commercial feed used as a treatment medium.
This study used an experimental method with a Completely Randomized Design (CRD) consisting of four treatments and six replications, resulting in 24 experimental units.
The treatments provided included commercial feed without turmeric extract as a control, as well as feed with the addition of turmeric extract at doses of 20 ml/kg, 50 ml/kg, and 80 ml/kg of feed.
Happa placement was carried out randomly to maintain data homogeneity and minimize research bias.
The tools used included happa, concrete tubs, water wheels, digital scales, rulers, thermometers, refractometers, pH meters.
DO meters, and other supporting tools.
The preparation of turmeric extract was carried out by maceration method using 96% ethanol solvent with a ratio of 1:3 for 3y24 hours with shaking every 24 hours, then filtered to separate the solution from the dregs.
The liquid turmeric extract obtained was applied to fish feed using a spray bottle according to the treatment dose and aired until dry so that the extract was well absorbed and did not easily dissolve in water.
Preparation of the container was carried out by installing 24 happa measuring 0.
5 y 0.
5 y 1 m in a pond that had been cleaned and filled with water to a height of 60 cm, and equipped with an aerator to maintain the availability of dissolved oxygen.
The research implementation included seed distribution after acclimatization for approximately 15 minutes with a density of 125 fish/mA, feeding 5% of the biomass weight four times a day, and sampling every 7 days to measure the growth of fish length and weight.
Water quality management was carried out through 40% water changes every week and monitoring of temperature, pH, salinity, and dissolved oxygen (DO).
The data obtained were analyzed using analysis of variance (ANOVA) with the help of IBM SPSS Statistics software version 26, and if there were significant differences, it was continued with the Least Significant Difference (LSD) test.
The parameters observed included Specific Growth Rate (SGR), absolute length growth.
Survival Rate (SR), and Feed Conversion Ratio (FCR).

Water Quality Monitoring Water quality in aquaculture is one of several factors contributing to the success of fish Water quality observations throughout the study showed that salinity, temperature, and dissolved oxygen were within normal limits and well tolerated by tilapia fry.
However, pH measurements showed less than optimal results.
The detailed water quality measurement data are as follows:
Temperature Based on the research results, the water temperature ranged from 27.
2 to 31.
1AC.
Referring to the National Standardization Agency (BSN), 1999, the optimum temperature for fish is 25Ae30AC.

on the Growth Rate of Tilapia Seed (Oreochromis niloticu.
The results of the study showed that compared to saline tilapia fry not given turmeric extract, the administration of turmeric extract in feed tended to increase the specific growth rate of fish, which is thought to be related to turmeric's ability to increase appetite and digestive efficiency (Rubai et al.
, 2.
Based on the results of the ANOVA analysis, the administration of turmeric extract at various doses had a significant effect on the specific growth of saline tilapia fry, so that further LSD tests were continued to determine the best treatment.
The test results showed that treatment D, namely the administration of turmeric extract at a dose of 80 e-ISSN : 2622-1934, p-ISSN : 2302-6049 Jurnal Perikanan, 16 .

Octaviani et al.
ml/kg of feed, produced the highest specific growth value.
The high growth in this treatment is thought to be due to the content of active compounds in turmeric, especially curcumin and essential oils, which play a role in improving digestion and absorption of nutrients such as protein, fat, and carbohydrates, so that energy from feed can be optimally utilized for growth (Wahyuningtyas et al.
, 2017.
Santika et al.
, 2.
In contrast, treatment A as a control without the addition of turmeric extract showed the lowest growth value, which is thought to be because the absorption of nutrients from commercial feed is not optimal without the addition of supporting herbal supplements, as reported that commercial feed without additional combinations has not been able to maximize the growth rate of fish (Rambo et al.
, 2.
Absolute Length Growth The BNT test results showed that turmeric extract significantly affected the absolute length growth of saline tilapia fry.
The treatment with the highest dose of turmeric extract .

produced the best length growth, while the treatment without turmeric extract showed the lowest results.
This was due to the more optimal consumption and utilization of feed energy in fish fed turmeric extract, thus supporting optimal metabolism and growth.
Survival Rate (SR) The high SR value in treatment D was due to the turmeric extract concentration in the treatment being within the acceptable range for the fish.
ANOVA results showed that the administration of turmeric extract on SR only had a significant effect in treatment D .
ml of turmeric extract/kg of fee.
This condition is suspected because the saline tilapia fry can adapt well to the feed provided.
Although the turmeric extract was administered at different doses in each treatment, the SR of the saline tilapia fry did not differ significantly between treatments.
The SR of saline tilapia fry depends on "the conditions of the waters where they live, namely the ratio of feed amount, density, and water quality including temperature, salinity, pH, and DO" (Riana et al.

On the other hand, treatment A .
had the highest FCR value, namely 6.
44, indicating that the feed was not used effectively for fish A lower feed conversion rate indicates that the amount of feed distributed is more beneficial for fish growth, referring to Anriyono, et al.
, .
On the other hand, a higher feed conversion value indicates that the amount of feed distributed is less beneficial for growth.
Water Quality Monitoring Water quality during the study was normal and supported the growth of saline tilapia Water temperature ranged from 27.
