Abstract

Adanya kasus pandemi COVID-19 menyebabkan berkurangnya pendapatan masyarakat Desa Pulao Semambu. Hal ini disebabkan oleh dua faktor yaitu pertama terhentinya berbagai agenda wisata yang dilakukan di Desa Pulau Semambu yang berimbas pada tidak adanya wisatawan yang membeli hasil panen, serta kedua, meskipun masyarakat masih tetap dapat menjual hasil pertaniannya di Pasar Indralaya, namun pandemi COVID-19 juga menyebabkan daya beli masyarakat menurun. Kebijakan pemerintah untuk work from home (WFH) berimbas pada tutupnya sebagian besar rumah makan yang berada di dalam dan di sekitar Universitas Sriwijaya, dikarenakan tidak adanya mahasiswa yang aktif hadir secara langsung sehingga kebutuhan akan sayuran dari Desa Pulau Semambu menjadi menurun. Tujuan kegiatan ini adalah memberikan informasi teknologi berupa budidaya ikan dengan memanfaatkan ruang pekarangan yang terbatas berupa Teknik budidaya ikan dalam ember (BUDIKDAMBER) serta pengolahan ikan berbasis zero waste. Kesimpulan dari kegiatan ini adalah tema kegiatan pengabdian tehnik budikdamber dan pengolahan ikan berbasis zero waste diterima dengan baik oleh masyarakat Desa Pulau Semambu, aktivitas diskusi dan tanya jawab yang berlangsung seru dan menarik. Paket bantuan berupa 5 unit budikdamber dan 5 unit hand sealer sangat bermanfaat untuk pemanfaatan teknologi secara langsung dari materi yang disampaikan dan diharapkan dapat memacu masyarakat untuk dapat mengaplikasikan ilmu/teknologi yang diperoleh.

Abstract

Log ratio is one of the change detection techniques often used in SAR image-based flood inundation analysis where the differences in characteristics between its polarizations are expected to complement each other and provide optimal predictions. This research aimed to identify the characteristics of the output generated from various potential combinations utilizing log ratio change detection. The study utilized Sentinel-1 GRD IW dual polarization mode before and during the flood event  as its main datasource. Briefly, the data processing consists of preprocessing, collocation, and change detection, which were subsequently followed by analysis and evaluation. The analysis results indicated a highly significant difference in characteristics among the four outputs of log ratio change, where the combinations of VH1/VH2 and VV1/VV2 detected much smaller changes compared to the combinations of VV1/VH2 and VH1/VV2. The VV1/VH2 combination acts as a counterpoint to the VH1/VV2 combination, as the changes identified in VV1/VH2 showed a tendency towards positive values, whereas the opposite is true for VH1/VV2. The evaluation results show that the highest frequency of errors in detecting changes sequentially was observed in the combinations of VH1/VV2, VV1/VH2, VV1/VV2, and VH1/VH2.

Abstract

Catfish (Clarias gariepinus) that are reared with probiotics as biofloc-forming agent is thought to increase the fish production. Applying swamp probiotics to the water media has never been studied to ensure the flocks' availability in the rearing media. This study aimed to determine the appropriate frequency of probiotics application collected from swamps for biofloc formation to improve the catfish production. This study used a completely randomized design with two treatments and three replications. The treatments were composed of different application frequency of swamp probiotics: (P1) once in 42 days of rearing and (P2) twice in 42 days of rearing. Data on flock volume, total bacterial colonies, absolute growth rate, feed efficiency, survival rate, and water quality were analyzed by T-test with a 95% confidence level. Meanwhile, the flock composition data were analyzed descriptively. The results showed that P2 obtained the best treatment with a floc volume of 68.33 10.41 mL/L, absolute length growth of 8.18 1.03 cm, absolute weight growth of 19.30 3.12 g, feed efficiency of 135.24 7.98%, survival rate of 89.33 6.21%, biomass production of 24639.50 1344.51 g, temperature of 28.85-29.59C, pH of 7.27-7.42, dissolved oxygen (DO) of 3.91-5.72 mg/L, ammonia of 0.45-1.15 mg/L, and total dissolved solids (TDS) of 717.33-885.50 mg/L. Therefore, swamp probiotics should be applied to catfish culture media twice for 42 days of rearing or once every 21 days.Keywords:BioflocCatfishProbiotics from swamp

Abstract

Floodplain swamp are seasonally inundated aquatic ecosystems that play vital ecological roles as habitats, spawning grounds, and natural buffers supporting local fish diversity in Indonesia, particularly in South Sumatra. However, pressures from land conversion, environmental degradation, and overexploitation have caused a decline in biodiversity and now threaten the long-term sustainability of these ecosystems. This study employs a Systematic Literature Review (SLR) approach, guided by the PRISMA protocol, to explore the role of socio-ecological approaches in managing floodplain swamp for fish conservation. The analysis was conducted through thematic and bibliometric synthesis using VOSviewer software to identify research trends, thematic clusters, and existing knowledge gaps. The findings reveal that the success of fish conservation in floodplain swamp depends not only on ecological factors but also on social, cultural, economic, and institutional dimensions. Integrating local wisdom such as the Lubuk Larangan system and traditional fisheries regulations with modern scientific frameworks like Adaptive Collaborative Management enhances socio ecological resilience and conservation effectiveness. An adaptive and participatory socio ecological management model for floodplain swamp is therefore essential to ensure the sustainability of fish resources and the well-being of local communities.

Abstract

Photoperiod manipulation is one of the environmental management strategies that can influence the physiological condition of fish and support the success of aquaculture production. This study aimed to analyze the photoperiod preference of Indonesian leaffish (Pristolepis grooti) during the the post-transportation recovery period. The experiment used a Completely Randomized Design with three photoperiod treatments and three replications: (A) 24 hours light:0 hours dark (24L:0D), (B) 12 hours light:12 hours dark (12L:12D), and (C) 0 hours light:24 hours dark (0L:24D). The study was conducted at the Experimental Pond Instalation, Aquaculture Study Program, Universitas Sriwijaya. The results showed that treatment C (0L:24D) produced the lowest blood glucose level (93.33±2.08 mg dL⁻¹), the highest feed efficiency (1.67±0.05%), and relatively better absolute weight growth (0.05±0.01 g), with a survival rate reaching 93.33±11.55%. The oxygen consumption level indicated significant differences in metabolic activity among treatments, reflecting the best physiological condition of Indonesian leaffish under a 24-hour dark photoperiod (0.110±0.008 mg O2 g-1 h-1). Water quality values during the recovery period (temperature 28.1-30.2°C, pH 7.6-7.9, dissolved oxygen 2.9-3.1 mg L⁻¹, and ammonia 0.421-0,895 mg L⁻¹) were within the range that supports the survival of Indonesian leaffish. Treatment C (0L:24D) indicated the photoperiod preference of Indonesian leaffish during the post-transportation recovery period because it was able to maintain better physiological conditions, thereby supporting improved aquaculture performance during the subsequent culture period.
