Abstract

Presence of water on earth not all of them can be used by living beings, especially humans. Watershed Loano Hulu is one of the watershed located in Central Java province. Loano DAS has a function for the area underneath. For the study of water balance is necessary to know the potential of water in the watershed, thereby criticality index can be determined so that the water in the watershed can be determined for watershed management measures are to be maintained. The purpose of this study is to determine the Water Holding Capacity (WHC) at the sites and determine the Water Balance. The research was conducted in the Upper Basin Loano Purworejo in Central Java Province. The research activities carried out in June 2009. The method used in the implementation of this study using the Thornthwaite-Mather. Data obtained on the basis of data WHC soil texture and extensive vegetation cover or land use, but it also needs climate data. Based on the results of the calculation results obtained WHC Loano watershed upstream of 245 mm. The size of the WHC reflects both the poor condition of a watershed. If the WHC of the watershed condition is very good, because it can save large amounts of water. Conversely the small WHC watershed condition is not good then it means the ability to store water is a small watershed. WHC value of  245 mm for the watershed Loano Hulu reflect the ability of the watershed to store water is high enough, so that the watershed is included in the DAS good condition. In meteorological amount of rainfall that occurred in the Upper Basin Loano big enough in January to reach 400 mm, the amount of rain up in June is still able to compensate for potential evapotranspiration occurs. Water deficit occurred during the five months from June to October occurred. Evapotranspiration that occurs less than the rainfall that occurred, so the watershed is a meteorologist had a surplus of water. Key words: soil, landuse, water holding capacity, water balance

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.

Abstract

This study evaluates land capability in Tafamutu Village, Moti District, Ternate City, as a basis for sustainable land-use planning. Employing the Land Capability Classification (LCC) framework and the Land Classification and Land Use Planning (LCLP) software, the analysis identifies five land capability classes (V–VIII) across sixteen land mapping units. Subclass V‑P1, occupying 7.6 ha (1.1%), is constrained by slow permeability (< 25 mm/h). In contrast, subclass V‑b3, covering 100.4 ha (14.9%), is characterized by high coarse fragment content (> 90%), resulting in splash erosion rates of up to 22.3% under intense rainfall. Class VI‑E, comprising 135.3 ha (20.1%), is defined by moderate slopes (30%–45%) and elevated surface runoff potential—up to 75% higher compared to gentle slopes (< 15%). Class VII‑e5 encompasses 143.9 ha (21.4%) and is marked by severe erosion, with rates reaching 1,738.2 t ha⁻¹ yr⁻¹. Class VIII‑G, the most significant area at 261.2 ha (38.9%), includes very steep slopes (> 65%) and is designated strictly for conservation purposes. The dominant soil textures are clay loam and sandy loam, with an average adequate depth of 80 cm and a pH range of 5.0–6.5. These edaphic conditions support the cultivation of cloves and nutmeg, contingent upon implementing appropriate soil conservation techniques such as terracing and organic mulching. Based on the land capability assessment, recommended land uses include grazing on Class V lands (108 ha; 16.5%), limited plantation development on Class VI (135.3 ha; 20.1%), production forestry on Class VII (143.9 ha; 21.4%), and strict protection as forest reserves on Class VIII (261.2 ha; 38.9%). These zoning guidelines are instrumental in promoting climate-resilient land management and the sustainable utilization of natural resources within coastal volcanic landscapes.

Abstract

Abstract Farming communities have not utilized agricultural waste and animal waste as compost optimally in overcoming the scarcity of fertilizer in farming communities. Composting is an alternative way of creating natural fertilizer made by farmers themselves, thus responding to the scarcity of fertilizer which in turn improves the health quality of the soil, produces healthy plant products, and increases farmers' income. The solutions offered in the program include the presentation of compost making materials, how to apply them to plants, assistance in plant cultivation business activities, post-harvest handling so that plant products can be maintained in a healthy manner. It is hoped that the farmers as partners who are accompanied can produce organic compost fertilizer which can increase crop production and increase their income. The aim of this program is to improve farmers' skills in utilizing plant litter, agricultural waste, animal waste to make compost fertilizer, which can then be sold on the market or used by farmers themselves to improve their vegetable cultivation business. Stages of activities include socialization, presentation of counseling material, creation of compost demonstration plots and plant cultivation demonstration plots with stages of land preparation, seeding, making plots, planting, fertilizing, watering, maintaining plants until harvest and marketing the results of cultivated plants.

Abstract

Dalam rangka peningkatan produksi pertanian sudah saatnya pengelolaan pertanian diarahkan pada input pemupukan yang ramah lingkungan dan pada lahan-lahan dengan produsktifitas yang rendah terutama dengan kondisi kesuburan rendah baik biofisik dan kimia. Pengelolaan lahan pertanian juga harus mampu memanfaatkan sisa hasil produksi yang tidak terpakai (limbah) dari tanaman maupun hewan untuk dijadikan sebagai pupuk organik. Dalam kegiatan ini sisa limbah pertanian yang digunakan adalah sebagai pupuk organik adalah pupuk kandang ayam, pupuk kandang sapi dan serasah dari cengkeh. Sedangkan media tanah pasir digunakan karena memiliki sifat kesubururan yang rendah baik biofisik dan kimia. Tujuan kegiatan ini adalah memanfaatkan sisa kotoran hewan sebagai pupuk organik dan tanah pasir dalam meningkatkan pengetahuan dan ketrampilan dalam bercocok tanaman sayuran. Sasaran peserta dalam kegiatan ini adalah kelompok tani atau petani yang mengusahakan budidaya tanaman sayuran dengan pendekatan metode penyuluhan dan diskusi mengenai budidaya tanaman serta aplikasi penerapan teknologi pertanian organik. Hasil kegiatan menunjukkan bahwa perlakuan pupuk kandang ayam, merupakan salah satu bahan organik tanah yang mampu memberikan produktifitas berat segar yang lebih baik dibandingkan dengan pupuk kandang sapi dan serasah cengkeh.

Abstract

Understanding groundwater flow dynamics through the Master Recession Curve (MRC) is critical in evaluating groundwater behavior following periods of extraction or cessation of rainfall. This study employs the Depuit-Boussinesq model for aquifer flow storage, wherein recession coefficients and constants are primary determinants of the MRC’s shape. This research aims to visualize the MRC using the Depuit-Boussinesq model to assess flow storage in small watershed areas within Ambon City, Maluku Province, Indonesia. The research methodology involved hydrological analysis across five watersheds, namely Wae Tomu, Wae Ruhu, Wae Batu Merah, and others, to model the relationship between recession constants, recession coefficients, and the MRC’s shape. Data collection included groundwater head and aquifer parameters measurements over the study period. The visualization results reveal variations in MRC shapes among the watersheds. The Wae Tomu Watershed exhibits a steeper MRC, indicating a sharp decline in groundwater head. In contrast, the Wae Ruhu and Wae Batu Merah Watersheds display more gradual MRCs, reflecting slower and steadier head declines. The recession constant of the Wae Ruhu Watershed is higher, indicating a larger storage capacity, while the Wae Tomu Watershed has a lower recession constant, representing limited storage capacity. Furthermore, changes in the recession constantly affect the delay in head reduction, influencing the MRC’s shape. This study underscores the significance of the relationship between recession coefficients, recession constants, and MRC shape in understanding groundwater flow dynamics. These findings provide valuable insights for more effective water resource management planning in small watershed areas.

Abstract

The availability of ruminant feed in Kulaba Village, Ternate City, is still dependent on the seasons, often disrupting livestock productivity. To address this, the community service program aims to increase livestock feed self-sufficiency through outreach and assistance in land use based on land capability data. The method used is a participatory approach, comprising stages of problem identification, spatial analysis of land capability maps, outreach and training, and the construction of demonstration plots (demplots) in yards, rain-fed rice fields, and marginal land. These activities have resulted in an increase in partners' understanding of land map symbols and interpretation, their ability to select forage crops according to land class, and their awareness of the importance of feed preservation through silage technology. Despite these improvements, the main obstacles, such as limited access to seeds, capital, and irrigation facilities, remain. However, the presence of demonstration plots and facilitation by farmer groups has helped accelerate the adoption of technology. As such, this program contributes to strengthening local food security and provides a foundation for the development of sustainable land-use systems in the future. Ketersediaan pakan ruminansia di Kelurahan Kulaba Kota Ternate masih bergantung pada musim, sehingga produktivitas usaha ternak kerap terganggu. Program pengabdian ini bertujuan meningkatkan kemandirian pakan ternak melalui sosialisasi dan pendampingan pemanfaatan lahan berdasarkan data kemampuan lahan. Metode yang digunakan adalah pendekatan partisipatif dengan tahapan identifikasi masalah, analisis spasial peta kemampuan lahan, sosialisasi dan pelatihan, serta pembangunan demonstration plot (demplot) di pekarangan, sawah tadah hujan, dan lahan marginal. Hasil kegiatan menunjukkan peningkatan pemahaman mitra terhadap simbol dan interpretasi peta lahan, kemampuan memilih jenis tanaman pakan ternak sesuai kelas lahan, serta kesadaran pentingnya pengawetan pakan melalui teknologi silase. Hambatan utama masih meliputi keterbatasan akses bibit, modal, dan sarana irigasi, namun adanya demplot dan fasilitasi kelompok tani terbukti mempercepat adopsi teknologi. Program ini berkontribusi dalam memperkuat ketahanan pakan lokal dan memberikan dasar bagi pengembangan sistem pemanfaatan lahan berkelanjutan di masa depan.
