Abstract

The availability of adequate water is one of the key factors in supporting increased food productivity, especially in areas that have large agricultural potential such as the Warsansom Watershed (DAS), West Papua. This research aims to predict water availability in the Warsansom watershed using the Soil and Water Assessment Tool (SWAT) model. The SWAT model was chosen because of its ability to simulate hydrological processes, erosion and land use dynamics in a spatial-temporal manner. The data used includes rainfall, temperature, topography, soil type and land use patterns. The analysis results show that the average annual rainfall is 322 mm/year, with an annual average temperature of 26.49°C. The Warsansom watershed area is dominated by secondary dryland forest (78.69%) which contributes significantly to groundwater infiltration and recharge. Regional delineation resulted in 33 sub-watersheds with a total area of ​​144,280 ha, as well as 273 hydrological response units (HRU) which became the basis for identifying critical areas in water management. SWAT simulations reveal potential risks of surface runoff in areas with steep slopes (36.53%) that require conservation interventions to reduce erosion and sedimentation. This research recommends data-based strategies for optimizing water resource management, including improving irrigation infrastructure, developing cropping patterns that are adaptive to water availability, and mitigating the impacts of climate change. By utilizing SWAT simulations, it is hoped that food productivity in the Warsansom watershed can increase sustainably, supporting food security in the West Papua region

Abstract

Kecamatan Bacukiki Barat di Kota Parepare memiliki potensi pertanian buah mangga yang cukup besar, namun sebagian hasil panennya, khususnya mangga berkualitas lewat matang (off grade), seringkali tidak termanfaatkan dan hanya dibuang. Kondisi ini mengindikasikan perlunya upaya diversifikasi pangan untuk meningkatkan nilai tambah hasil pertanian lokal. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberikan solusi melalui sosialisasi dan pelatihan pengolahan mangga off grade menjadi selai kepada Kelompok Wanita Tani (KWT) Masagenae Kecamatan Bacukiki Barat Kota Parepare. Metode pelaksanaan meliputi observasi, perencanaan, penyampaian materi, praktik, dan evaluasi. Materi mencakup pemahaman tentang nilai gizi buah mangga, proses pengolahan menjadi puree, hingga tahap akhir produksi selai. Kegiatan ini juga mengenalkan teknik sterilisasi sederhana guna memperpanjang umur simpan produk. Hasil kegiatan menunjukkan bahwa para anggota KWT Masagenae sangat antusias dalam memperoleh keterampilan baru, dan mampu memproduksi selai dari mangga yang sebelumnya dibuang. Inisiatif ini diharapkan dapat menjadi langkah awal dalam mendorong diversifikasi pangan, meningkatkan pendapatan keluarga, serta mendukung program pemerintah dalam mencapai ketahanan pangan dan tujuan pembangunan berkelanjutan (SDGs) poin ke-2, yaitu bebas kelaparan. Pengolahan skala rumah tangga ini berpotensi menjadi sumber ekonomi kreatif lokal apabila terus dikembangkan secara berkelanjutan

Abstract

The use of non-food dyes is a problem in food safety. One of the efforts to solve this problem is the making of natural coloring products from purple sweet potato anthocyanin pigments. Anthocyanins are sensitive to oxidative damage, so encapsulation techniques need to be used to preserve bioactive compounds. Encapsulation with the coacervation method involves coating anthocyanins as the active ingredient with pectin and alginate as gel matrices, based on the principle of ionic gel formation. This study aimed to determine the optimal alginate concentration for the formation of anthocyanin encapsulates and to identify the color characteristics and interactions of the encapsulated anthocyanins from purple sweet potato. This study used various concentrations of alginate (0%, 0.5%, 1%, and 1.5%). The research parameters used were total anthocyanin and antioxidant activity (IC50). The findings indicated that the optimal concentration of alginate for preserving the solubility and stability of anthocyanin, derived from the bioactive compounds in purple sweet potatoes, was 1% alginate. This concentration resulted in a total anthocyanin content of 20.77 mg/L and an antioxidant activity (IC50) of 4049.73 ppm. A higher alginate concentration results in stronger gel formation; however, it simultaneously weakens the ability of alginate to bind anthocyanin as an active ingredient. This is attributed to the increase in viscosity, making the incorporation of the anthocyanin matrix into the encapsulates more difficult. Despite the very weak antioxidant activity, these anthocyanin encapsulates hold potential as natural food colorants for safe applications in acidic food products like beverages.
