Abstract

ABSTRACT The increase in damage are experienced by many watershed due to human interactions and interventions which impacted in the hydrological balance that may lead to disasters. Flooding is a routine hydrological disaster that occurs in the Jambo Aye Basin. This study aims to analyze the relationship of the hydrological characteristics of the Jambo Aye Basin to the potential and occurrence of floods. Characteristics of slope, soil movement, hydrological soil group (HSG) analysis, antecedent precipitation index (API) and runoff curves are used as hydrological indicators to identify potential flooding in the watershed. The analysis show that the Jambo Aye Basin is proned to flooding. The potential for inundation floods is found in the downstream area which has the characteristics of gentle slopes (12%), very low infiltration capacity (37,95%), high runoff curve values (17%) and high levels of wetness (26%). Flash floods have the potential to occur in the upstream area which has the characteristics of steep slopes, soil movement and high rainfall. Integrated watershed management needs to be carried out in the Jambo Aye Basin considering the frequent occurrence of floods. Keywords: antecedent precipitation index; flash floods; flood; curve numbers; land use ABSTRAKDaerah Aliran Sungai (DAS) mengalami peningkatan kerusakan akibat hubungan dan interferensi manusia yang berdampak pada kesetimbangan hidrologi sehingga terjadi bencana.

Abstract

Meningkatnya permintaan masyarakat akan sayuran mendorong petani untuk meningkatkan produksinya. Upaya yang dapat dilakukan untuk meningkatkan hasil panen antara lain penggunaan pupuk. Pemupukan dengan pupuk kimia merupakan alternatif yang sering dilakukan, namun kelangkaan pupuk kimia di pasaran membuat pupuk tersebut semakin mahal, sehingga perlu dicari alternatifnya. Pembuatan pupuk organik dari limbah tanaman merupakan salah satu alternatif yang memungkinkan, dengan teknologi EM yang akan mempercepat proses produksi pupuk. Kegiatan pengabdian ini dilaksanakan di Kelurahan Kalumata Kota Ternate Selatan dengan tujuan membantu petani mengelola limbah pertaniannya dengan memanfaatkannya sebagai pupuk organik. Peserta pengabdian adalah anggota Kelompok Petani Sayur "Masure". Metode yang digunakan adalah metode penyuluhan dan demonstrasi. Kegiatan dilakukan secara langsung dengan anggota kelompok tani, diawal dan diakhir kegiatan dilakukan penilaian untuk mengetahui tingkat pengetahuan peserta pengabdian. Hasil evaluasi menunjukkan bahwa pengetahuan dan pemahaman anggota kelompok tani “Masure” mengalami peningkatan. Hal ini tercermin dari peningkatan nilai tes akhir, dimana sebagian besar anggota mendapat nilai di atas 80. Peserta dalam kegiatan ini juga dapat memproduksi pupuk organik sendiri dengan memanfaatkan limbah organik dari sisa tanaman pasca panen dan kulit buah.

Abstract

Variability of soil types in the Quaternary geological formations on the islands presents different soil morphological characteristics. The process of geomorphogenesis and geology determines the characteristics of soil morphology. This study aims to determine the characteristics of soil morphology, pedogenesis process, soil development based on landforms in Quaternary geological formations in North Maluku Islands region. Six soil profiles were observed, which were determined based on geographical location. Descriptive research methods based on USDA standards were used as the basis for determining soil morphological characteristics. The results showed that the pedogenesis process on Quaternary volcanic landforms were caused by a period of volcanic eruptions characterized by thick soils (>100 cm), fairly steep slopes (15 - 25%), no rock outcrops, and an eluviation-illuviation process on the soil profile. While the pedogenesis process on alluvial landforms tends to produce in-situ rock weathering characterized by slow horizon formation and produces a relatively shallow soil solum (<100 cm). The data obtained provide information on soil resources and the research results can also be used as a formulation in conservation efforts on the islands.

Abstract

The availability of high-quality and sustainable livestock feed remains a major challenge in the development of the livestock sector, particularly in West Halmahera. One of the key factors affecting livestock feed availability is land suitability for forage crop cultivation. Bangko Hamlet in Bobane Igo Village possesses extensive land potential, but its utilization has not been optimized. This study aims to evaluate the suitability of the area’s land for forage crops such as Calliandra, Leucaena, and Napier grass. The research employed the matching method, comparing land characteristics with land suitability criteria. The results indicate that the actual land suitability ranges from S2 (moderately suitable) to N1 (not suitable). The main limiting factors identified include water availability (dry months and rainfall), erosion levels, nutrient retention (base saturation and organic matter content), and topography affecting drainage and slope. Improvement efforts such as fertilization, water management, soil conservation, and erosion control can enhance potential land suitability to the S2 class. This study recommends management strategies based on limiting factors to support sustainable land utilization and meet the livestock feed demand in the area.
