PERFORMA PERTUMBUHAN IKAN NILA (Oreochromis niloticus) YANG DIBERIKAN PAKAN DENGAN PENAMBAHAN SINBIOTIK (Lactobacillus spp. x Ipomoea batatas L.) PADA DOSIS YANG BERBEDA
Tilapia production is greatly influenced by feed as a source of energy and nutrients that support growth, health, survival, and reproduction. The growth rate of fish is closely related to feed quality, so that growth optimization can be achieved through the provision of quality feed. The ingredient that can be used as an alternative for optimizing feed quality is purple sweet potato flour (Ipomoea batatas L.). The purpose of this study was to determine the effect of commercial feed added synbiotics with different doses on the growth rate of tilapia. This study used a complete random design method with 3 treatments, with a maintenance duration of 56 days. Each treatment uses commercial feed, treatment 1 is control, treatment 2 is 1.5% prebiotic and probiotic 2%, treatment 3 is 2% prebiotic and probiotic 2%. The results of the assumption test stated that treatment 3 obtained a significant number as well as the highest score with an absolute weight of 28.59, SGR of 3.32, FER of 78.4, FCR of 1.28. This value illustrates that synergibiotic feed has the potential to improve the quality and quality of feed which leads to the growth rate of tilapia.

Dogol shrimp (Metapenaeus monoceros) is a high-value fishery commodity widely caught in the waters of Sungai Kakap, Kubu Raya Regency, West Kalimantan. Growing market demand and increasing fishing pressure are potential threats to the sustainability of dogol shrimp populations in this area. This study aimed to examine the current condition of dogol shrimp resource exploitation and to assess its utilization status based on size structure, length-weight relationship, first capture size (Lc50%), and asymptotic length (L∞). A descriptive method was applied with simple random sampling at the Sungai Kakap Fish Landing Site (TPI). Sampling was conducted four times from September to December 2025. A total of 785 shrimp were measured, consisting of 284 males and 501 females. The results showed that carapace length ranged from 14.36 to 50.52 mm, with the highest frequency in the 25–27 mm range. Both male and female shrimp exhibited negative allometric growth, expressed by the equations W = 0.010064814L^1.877310535 and W = 0.026226481L^1.579042932, with b values of 1.877 and 1.579, respectively. The Lc50% value was 26 mm, while L∞ for males was 38.79 mm and for females was 53.18 mm. Comparison of Lc50% with half the L∞ value indicated that the shrimp caught had approached the appropriate harvest size. Nevertheless, regulation of mesh size remains necessary to ensure the long-term sustainability of dogol shrimp resources in the Sungai Kakap waters.

PENGARUH FORTIFIKASI TEPUNG TULANG IKAN NILA (Oreochromis niloticus) TERHADAP KARAKTERISTIK SENSORIS MIE KERING DAN POTENSINYA SEBAGAI SUMBER KALSIUM
This study aimed to analyze the effect of tilapia bone flour (Oreochromis niloticus) fortification on the sensory characteristics of dry noodles and to evaluate its potential as a natural calcium source. The study employed a laboratory experimental method with three fortification treatments of tilapia bone flour, namely 3% (F1), 6% (F2), and 8% (F3). The observed parameters included appearance, aroma, taste, and texture using a 1–5 hedonic scale test involving untrained panelists. Data were analyzed using the Kruskal–Wallis test at a 5% significance level. The results showed that fortification of tilapia bone flour up to 8% concentration did not significantly affect all organoleptic parameters (p>0.05). The highest average scores were obtained in treatment F1 for appearance (3.97), texture (4.03), and taste (3.76), while the highest aroma score was 3.59. The F1 formulation with 3% tilapia bone flour fortification was considered the best treatment based on panelists’ acceptance level. The high calcium content in tilapia bone flour indicates its potential utilization as a functional food fortification ingredient derived from fishery by-products. This study demonstrates that tilapia bone flour has the potential to be used as a natural calcium source without significantly reducing the sensory quality of dry noodles.

Freshwater lobster (Cherax quadricarinatus) is a high-value aquaculture commodity with rapid growth and strong adaptability. However, the high cost of feed—accounting for 60–70% of total production expenses—remains a major constraint for farmers. The use of alternative plant–animal feed combinations offers a potential solution to reduce production costs without compromising nutritional quality. This study aims to analyze the effect of different proportions of alternative feed combinations on the absolute weight gain of freshwater lobster juveniles, determine the most optimal feed composition, describe growth patterns, and evaluate water quality as a supporting factor. The research was conducted for four weeks using an experimental method with a Completely Randomized Design (CRD) consisting of five treatments and five replications. The results showed that feed combinations had a highly significant effect on growth. Treatment D (25% plant-based + 75% animal-based feed) produced the highest absolute weight gain of 10 g, indicating that animal protein plays a dominant role, while plant-based nutrients remain essential for balanced nutrition. Overall, plant–animal alternative feed combinations effectively enhanced the growth of freshwater lobster juveniles and present a cost-efficient alternative to commercial feed for farmers.

The study was conducted experimentally using four treatments: A (no probiotic/control), B (2 ml/kg feed), C (3 ml/kg feed), and D (4 ml/kg feed), each with three replications. Shrimp were stocked at a density of 100 individuals per liter and reared in a controlled system. Observed parameters included survival rate (%), absolute weight gain (g), specific growth rate (SGR, %/day), and water quality. The results showed that probiotic supplementation influenced the survival and growth performance of vannamei shrimp, although the differences were not statistically significant (p > 0.05). Treatment B (2 ml/kg feed) yielded the highest results, with a survival rate of 61.3%, an average absolute weight gain of 8.8 g, and the highest specific growth rate compared to other treatments. Treatment A (without probiotics) showed the lowest performance in both survival and growth. Water quality parameters (temperature, pH, DO, and ammonia) were within the optimal range for vannamei shrimp growth.

ANALISIS DAMPAK KONVERSI LAHAN TAMBAK MENJADI SAWAH TERHADAP SOSIAL EKONOMI MASYARAKAT KECAMATAN MATTIRO SOMPE KABUPATEN PINRANG
Pond farmers in Mattiro Sompe District turned their ponds into rice fields due to a decrease in crop yields, limited seawater availability for saltwater fulfillment in ponds because the estuary experienced siltation which caused ponds far from the estuary to experience. This study aims to identify the factors that affect the conversion of pond land into rice fields and evaluate their impact on the socio-economic conditions of the people of Mattiro Sompe District, Pinrang Regency. Using multiple linear regression analysis with the help of SPSS, it was found that more stable availability of irrigation water and decreased pond productivity were the main drivers of conversion. Economically, people's income increased significantly from an average of Rp8,500,000 to Rp25,855,000 after conversion, with conversion cost as the most influential variable (p = 0.000) and R² value of 0.799. Although there were no statistically significant social variables, land type had the highest contribution to social change (β = 0.316), with an R² of 0.783 indicating the strength of the model. These findings conclude that land conversion has a positive economic impact, but needs to be balanced with attention to social dynamics in the process of adaptation and management of community conflicts.
