Chitala lopis, also known as giant featherback, is a fully protected fish species on Indonesian official list due to the susceptibility to exploitation. Several studies showed that the conservation of aquatic resources, such as giant featherback, could be achieved through the implementation of fish farming practices and optimization of feed use. Therefore, this study aimed to determine effect of different feeding rate on growth pattern, performance, and condition factor of the first generation of giant featherback. The first generation of fish was collected from the natural reproduction of broodstock in the earthen ponds. A total of 5 samples were then randomly divided into three treatment groups and reared in the nine net cages installed in the earthen pond. The stocking density in each group was three fish per cage, and the treatments were carried out in triplicates. Feed given comprised fish bycatch as control (T0) (5% of the total weight) and freshwater shrimp, Caridina sp. with two different feeding rates, namely 5% (T1) and 7% (T2) of the total weight. The mean initial weight of all the samples in this study was 41 3.85 g. The results showed that the highest survival and absolute growth rates (29.96.38 g, 78 11%) were obtained in T1, but were not significantly different (p0.05). Furthermore, the highest average relative growth rate was also found in T1 (76.2818.61%) and significantly different compared to other treatments (p0.05). Growth pattern of fish at the beginning of the experiment was negative allometric (0.54), showing a low correlation (0.03), but became positive allometric (4.17) at the end, with moderate correlation (0.66). The results also showed that the highest condition factor was obtained in T2 (0.780.03), and there was a significant effect (p0.05). Based on the results, Caridina sp. had a positive and significant impact on the weight growth of the first generation of giant featherback compared to other studies.Keywords:CultivationFeeding rateGiant featherbackCaridina sp.Rasbora sp.

Corporate Social Responsibility (CSR) bertujuan untuk melihat peningkatan Kinerja Perusahaan dalam Pengelolaan Lingkungan Hidup, mengatur mekanisme potensi peranan perusahaan yang sangat besar dalam penangan bencana. Rapid Environmental Impact Assesment in Disasters (REA) memprioritaskan kesejahteraan masyarakat yang disebabkan oleh kebencanaan dengan mengidentifikasi dan memasukkan isu lingkungan ke dalam tahap awal proses tanggap untuk meminimalisir dampak negatif yang ditimbulkan dari bencana yang terjadi. Kelurahan Plaju Ulu merupakan kawasan yang terletak di Ring 1 perusahaan sehingga perusahaan bertanggung jawab dalam meningkatkan kapasitas warga dengan melakukan mitigasi kebencanaan. Adapun rumusan masalah yang diangkat sebagai berikut: (1) Melakukan analisa resiko dan kerentanan sosial, lingkungan dan fisik dengan menggunakan prinsip rapid environmental impact assessment in disaster (REA). (2) Perencanaan program pemberdayaan masyarakat binaan di daerah yang terkena bencana di untuk mendukung kegiatan penanganan dan penanggulangan bencana. Hasil penelitian diperoleh, potensi kebencaanaan yang dihadapi Kelurahan Plaju Ulu yaitu kebakaran dan covid-19. Namun kerentanan kebencanaan lebih banyak di sebabkan memiliki modal sumber daya manusia, finansial, infrastruktur, Sumber daya alam, dan sosial cukup baik diantaranya Memiliki banyak penduduk usia produktif dan sebagian warganya menjalankan UMKM, Kegiatan gotong royong masih dijalankan rutin. 2) Rekomendasi program pemberdayaan masyarakat yang ditawarkan yaitu pembentukan kampung UMKM Plaju Ulu, pemanfaatan limbah tempe dengan pembuatan pakan ternak dan pembangunan IPAL, dan pembentukan satgas siaga covid-19 untuk mengurangi wabah covid-19.

The results of the tempe-making process will produce waste that is harmful to theenvironment from the washing, boiling, pressing and printing processes. The tempeindustry in Plaju ulu village is a source of community income. Tempe industryactivities produce waste that can pollute the environment, causing unpleasant odors.The wastewater treatment plant built by Pertamina RU 3 Plaju has a positive impactin reducing the impact of the tempe industry liquid waste. The formulation of theproblem raised (1) The results of the effectiveness of the Plaju Tempe IndustryWWTP. (2) Recommendations for WWTP technology that can be used in the PlajuTempe Industry. The parameters used to measure the quality of the effluent are pH(degree of acidity), COD, BOD, TSS, and (Total Suspended Solid) during July andAugust 2022. To determine the quality of wastewater produced, data fromlaboratory test results must be compared with quality standards. waste water inaccordance with the Regulation of the Minister of Environment of the Republic ofIndonesia No. 5 of 2014. From the results of the processing effectiveness, theeffectiveness of COD, BOD, and TSS was found to be 53.81%; 11.05%; and 22.65%.From the results of this processing, it is still considered not able to reduce thepollutants generated from the tempe industry activities. The pH and TSS parametersstill do not meet the quality standards. The recommended waste treatment isanaerobic biofiltration, anaerobic digester, and phytoremediation in improving theparameters of pH, COD, BOD, and TSS in the tempe-making industry
