Abstract

Purpose: The catfish farming training using the biofloc system conducted for the Tirta Bahari Youth Group in Jamaimo Village aims to enhance the skills and knowledge of the fisheries group in utilizing biofloc technology as an efficient, sustainable, and environmentally friendly aquaculture method. Methodology: The biofloc system boosts fish farming productivity by using microorganisms to process feed waste and excrement into an additional nutrient source. Results: This training covered biofloc pond design, introduction of microorganisms, water quality monitoring for catfish growth, and maintenance management through aeration control and measurement of key parameters, such as pH, dissolved oxygen, and ammonia, to maintain pond stability. Conclusions: This training is expected to enhance the knowledge and skills of the Tirta Bahari Youth Group in biofloc-based fish farming, enabling them to apply it independently and sustainably. In the long term, this initiative is expected to strengthen the local economy by creating business opportunities in the aquaculture sector, enhancing food security, and empowering the Tirta Bahari Youth Group and other youth as agents of change who can contribute to sustainable fishery resource use in Jamaimo Village. Limitations: The time available for training may not be sufficient to cover all technical aspects in depth; therefore, participants may not be fully prepared to implement the biofloc system independently. Contribution: This service can have a wide and sustainable positive impact on the Jamaimo Village community.

Abstract

Well water used by the community often does not meet quality standards because it contains high levels of iron (Fe) and manganese (Mn). This study was intended to reduce Fe and Mn levels in well water by using filtration technique with activated charcoal media. The effect of hydraulics and backwash dynamics on the efficiency of filtration process was also investigated. The filtration apparatus was made of PVC pipe with the diameter of 4 inches and 120 cm height. The determination of optimum hydraulic conditions of filtration was carried out by varying the size of the activated carbon filter media (8-10, 12-14, and 16-18 mesh) and flow rate (1, 2, and 3 L/min) at the service time of 10 hours. The results showed that the size of filter media has significant effect on removal efficiency of Fe and Mn, with the most effective size was 16-18 mesh with the removal efficiency of 83.33% (Fe) and 93.33% (Mn). The highest head loss value in the filtration column was 0.15 cm, which occurred at the flow rate 3 L/min. Backwash should be performed after filtering process of 35 hours, 44 hours and 55 hours at the flow rate 1 L/min, 2 L/min, and 3 L/min repectively. The single filter design in this study reduced Fe and Mn concentration to meet clean water quality standards.

Abstract

Abstrak: Produktivitas pertanian yang optimal merupakan tantangan besar bagi petani. Pengabdian masyarakat ini bertujuan untuk meningkatkan hardskill dan softskill kelompok tani "Malawo Sejahtera" di Kelurahan Jamaimo, Distrik Mariat, Kabupaten Sorong melalui sosialisasi dan pendampingan penyemaian benih sayuran. Kegiatan ini melibatkan 22 peserta dari kelompok tani "Malawo Sejahtera" dan difokuskan pada budidaya sayuran seperti terong, sawi, dan bayam yang dinilai mudah dibudidayakan serta memiliki nilai ekonomi tinggi. Sosialisasi dilakukan untuk memberikan pemahaman dasar tentang teknik penyemaian yang efektif, diikuti dengan pendampingan langsung untuk memastikan praktik di lapangan sesuai dengan teori. Evaluasi dilakukan melalui pre-test dan post-test untuk mengukur peningkatan pengetahuan dan keterampilan peserta, serta observasi langsung terhadap hasil praktik di lapangan. Hasil menunjukkan peningkatan pengetahuan dan keterampilan peserta dari 61,18% menjadi 85,56% dengan bibit yang lebih sehat dan siap tanam sebagai indicator keberhasilan. Dengan pendekatan partisipatif dan pendampingan yang intensif, diharapkan produktivitas kelompok tani "Malawo Sejahtera" dapat meningkat secara berkelanjutan.Abstract: Optimal agricultural productivity remains a significant challenge for farmers. This community service program aims to enhance both the hardskills and softskills of the "Malawo Sejahtera" farmer group in Jamaimo Village, Mariat District, Sorong Regency, through socialization and mentoring on vegetable seedling techniques. The activity involved 22 participants from the "Malawo Sejahtera" farmer group and focused on cultivating vegetables such as eggplant, mustard greens, and spinach, which are considered easy to grow and have high economic value. The socialization provided a basic understanding of effective seedling techniques, followed by direct mentoring to ensure field practices aligned with the theoretical knowledge. Evaluation was conducted using pre-test and post-test assessments to measure participants' knowledge and skill improvement, along with direct observation of field practices. Results showed an increase in participants' knowledge and skills from 61.18% to 85.56%, with healthier and more transplant-ready seedlings as an indicator of success. With a participatory approach and intensive mentoring, the productivity of the "Malawo Sejahtera" farmer group is expected to improve sustainably.
