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.

Abstract

Catfish (Clarias gariepinus) farming is the dominant freshwater aquaculture in Palembang, South Sumatra, serving as both a key livelihood and a major source of local food security. Despite its importance, few studies have examined its economic contribution at the household level. This study analysed the income structure of 60 catfish-farming households in Sukarami, Sematang Borang, Gandus, and Plaju districts, focusing on costs, profitability, and diversification. Data were collected during January–June  2025 through structured interviews, field observations, and official records. Findings show that production is highly operationally  intensive, with feed and seed accounting for 94.30 % of total costs. Despite this, catfish farming remains profitable, generating an average net income of IDR 14.14 million per cycle, or IDR 56.54 million annually. The activity accounted for 61.30% of household income, confirming its role as the primary livelihood source. Complementary activities, including Pangasius sp. farming (15.50 %) and non-fisheries income (23.20 %), provided diversification that mitigates risks and stabilizes cash flow. Overall, catfish aquaculture sustains household economies in Palembang but remains highly vulnerable to fluctuations in input prices and market instability. However, the sector remains highly susceptible  to fluctuations in input prices and market instability. Policy interventions should, therefore, prioritize improvements in feed efficiency, access to quality seed, and cooperative procurement, along with income diversification, to strengthen household resilience and ensure the socio-economic sustainability of small-scale aquaculture.

Abstract

Abstrak: Desa Perigi memiliki wilayah dengan ekosistem gambut. Dalam praktiknya, pengelolaannya menghadapi banyak tantangan. Pelatihan dan pengabdian masyarakat ini bertujuan untuk meningkatkan pemahaman petani tentang inovasi pengelolaan gambut berkelanjutan melalui pendekatan pelatihan berbasis Participatory Rural Appraisal (PRA). Metode ini meliputi pemberian materi, diskusi kelompok, dan identifikasi potensi lokal untuk mengembangkan praktik cerdas iklim. Kegiatan dilaksanakan di Desa Perigi, Kecamatan Pangkalan Lampam, Kabupaten Ogan Komering Ilir, pada 10 September 2024. Mitra kegiatan ini bersama kelompok tani Desa Pergi dengan jumlah peserta 30 orang petani dan didukung oleh perangkat desa setempat. Hasil kajian menunjukkan bahwa petani telah mempelajari dan mengalami peningkatan pemahaman tentang praktik agroforestri, paludikultur, dan pengelolaan lahan tanpa bakar. Sebanyak 63,33% petani bersedia mengimplementasikan ide inovasi yang diberikan, meskipun masih terdapat kendala berupa keterbatasan modal, tenaga kerja, dan dukungan pemerintah. Kegiatan ini berhasil mengidentifikasi potensi lokal, meningkatkan produktivitas, dan memperkuat komitmen terhadap pengelolaan gambut yang ramah lingkungan dan berkelanjutan. Pendekatan ini menunjukkan bahwa kolaborasi antar pemangku kepentingan, edukasi masyarakat, dan strategi pengelolaan berbasis inovasi cerdas iklim dapat menjadi solusi untuk mengatasi degradasi lahan gambut. Dengan langkah-langkah ini, diharapkan ekosistem gambut akan tetap lestari dan dapat memberikan manfaat ekonomi dan ekologi berkelanjutan untuk masa depan.Abstract: Perigi Village has an area with a peat ecosystem. In practice, its management faces many challenges. This training and community service aims to improve farmers' understanding of sustainable peat management innovations through Participatory Rural Appraisal (PRA)-based training approach. This method includes providing materials, group discussions, and identifying local potential to develop climate-smart practices. The activity was carried out in Perigi Village, Pangkalan Lampam District, Ogan Komering Ilir Regency, on September 10, 2024. The partners for this activity are the farmer groups in Perigi Village, with 30 participating farmers, and supported by the local village officials. The results of the study showed that farmers had learned and experienced an increase in understanding of agroforestry practices, paludiculture, and land management without burning. As many as 63.33% of farmers were willing to implement the innovation ideas provided, although there were still obstacles in the form of limited capital, labor, and government support. This activity succeeded in identifying local potential, increasing productivity, and strengthening the commitment to environmentally friendly and sustainable peat management. This approach shows that collaboration between stakeholders, community education, and climate-smart innovation-based management strategies can be solutions to overcome peatland degradation. With these steps, it is hoped that the peat ecosystem will remain sustainable and can provide sustainable economic and ecological benefits for the future.
