Abstract

Pencemaran mangan (Mn) dalam air dapat menimbulkan dampak negatif terhadap kesehatan dan kualitas lingkungan, sehingga diperlukan metode pengolahan yang efektif dan ekonomis. Penelitian ini bertujuan untuk membandingkan kemampuan limbah kulit nangka dan kulit jengkol dalam menurunkan konsentrasi mangan terlarut dalam larutan aqueous. Percobaan dilakukan dengan menambahkan 1 g biomassa ke dalam larutan MnSO4 artifisial, selama 30 menit kemudian difiltrasi untuk memperoleh fraksi mangan terlarut. Variasi perlakuan meliputi arang kulit jengkol tanpa aktivasi, pelet kulit nangka, serbuk kulit nangka (100 mesh), biochar kulit nangka, serta manganese greensand sebagai pembanding. Konsentrasi Mn dianalisis menggunakan metode spektrofotometri serapan atom, dan data diuji secara statistik menggunakan ANOVA dan uji lanjut Tukey HSD. Hasil penelitian menunjukkan bahwa penggunaan arang kulit jengkol menurunkan konsentrasi Mn sebesar 4,81%. Serbuk kulit nangka dan biochar kulit nangka menunjukkan efisiensi penurunan tertinggi, masing-masing sebesar 65,4% dan 69,1%. Terdapat perbedaan signifikan antara perlakuan menggunakan kulit jengkol dan kulit nangka. Namun, tidak terdapat perbedaan signifikan antara serbuk kulit nangka dan biochar. Perlakuan lainnya tidak berbeda signifikan terhadap kontrol. Hasil ini menunjukkan bahwa limbah kulit nangka berpotensi sebagai bahan adsorben yang efektif, ekonomis, dan ramah lingkungan untuk pengolahan air tercemar mangan. Ukuran partikel dan luas permukaan biomassa berperan penting dalam penurunan mangan terlarut.

Abstract

Usaha peningkatan nilai tambah ubi kayu dapat dilakukan dengan cara penganekaragaman produk olahan ubi kayu menjadi bahan setengah jadi (produk antara) yang selanjutnya dapat langsung dipasarkan atau menjadi produk makanan siap saji. Saat ini, di Kecamatan Kamang Magek Kabupaten Agam usaha penganekaragaman produk olahan ubi kayu banyak dilakukan oleh industri skala rumah tangga (IRT). Namun, dalam proses pengolahannya beberapa IRT masih menggunakan teknologi sederhana sehingga produktivitas dan pendapatan usaha terbatas pada kemampuan teknologi yang digunakan. IRT Erna (mitra) masih menggunakan metode pengeringan konvensional berupa pengeringan melalui panas matahari. Hal ini akan menyebabkan ketergantungan produksi kerupuk ubi terhadap perubahan cuaca. Ketersediaan teknologi pengering dengan menggunakan panas buatan sebagai pengganti panas matahari belum mampu menjadi solusi pengering kerupuk ubi bagi IRT pengolah kerupuk ubi di Sumatera Barat. Kerupuk ubi yang dikeringkan secara paksa menyebabkan ketidakmerataan suhu pengeringan pada produk kerupuk ubi. Untuk itu, perlu dilakukan introduksi teknologi pengering tenaga surya yang dirancang berdasarkan kebutuhan mitra. Dari hasil kegiatan ini dapat disimpulkan bahwa teknologi yang diintroduksikan mampu meningkatkan produktivitas produksi kerupuk ubi hingga 2 kali lipat dari proses produksi dengan menggunakan teknologi konvensional sebelumnya.

Abstract

The purpose of this community service activity is to assist the recovery of social activities and address the crisis of electricity and clean water following the flash floods in Pesisir Selatan Regency, particularly in Kampung Langgai and Barung-Barung Balantai Health Center, which were the most severely affected areas. The methods employed included conducting a needs assessment survey of the affected communities, procuring and installing a 5.5 kW generator set at Nurul Wahidah Mosque as a social center, distributing ten solar-powered lamps to residents’ homes, and rehabilitating the clean water system at the health center by replacing the water pump and installing new piping networks from the ring well and Pamsimas sources. Additionally, training was provided on the operation and maintenance of electrical equipment, along with socialization on the importance of clean water to prevent post-flood diseases. The results demonstrated a significant improvement in access to electricity and clean water in the affected areas. The mosque resumed its function as a center for social activities, homes and roads received adequate lighting, and health services at the health center became fully operational again. The conclusion of this activity is that appropriate technology-based interventions, such as the provision of generator sets, solar lamps, and water filtration system repairs, are effective in supporting post-disaster recovery and enhancing community resilience. The sustainability of the program can be strengthened through regular training and cross-sector collaboration to build resilient infrastructure in disaster-prone areas.

Abstract

This community engagement program aims to improve irrigation efficiency and reduce farmers' dependence on rain-fed water through the implementation of solar-powered pumping technology in Nagari Tanjung Barulak, Tanah Datar Regency, West Sumatra, Indonesia. The program adopted a Participatory Action Research (PAR) approach, actively engaging farmers in the planning, installation, training, and evaluation of the irrigation system. The intervention included the installation of a 25 kWp solar-powered pumping system equipped with photovoltaic (PV) panels and a DC submersible pump, followed by operational and maintenance training for approximately 30 farmers. The results demonstrated that the system was capable of irrigating approximately 100 hectares of agricultural land on a rotational basis, increasing irrigation water availability by up to 60% compared with previous conditions. In addition, irrigation operating costs were reduced by approximately 40% due to decreased reliance on fossil fuels. Farmers' knowledge and technical skills also improved substantially, with 85% of participants able to operate the system independently after completing the training. The program produced a fully functional solar-powered pumping system, practical training modules, and a community-based irrigation management group to ensure long-term sustainability. Overall, the findings indicate that implementing solar-powered irrigation through a participatory approach is an effective strategy for enhancing irrigation efficiency, lowering production costs, and strengthening farmers' capacity to manage water resources independently. The program offers a scalable and sustainable model that can be replicated in other regions with similar environmental and socio-economic characteristics.
