Abstract

Embung Sirani, located 10 km from the capital city of Belu District, East Nusa Tenggara Province, is the biggest of the 27 embungs in this area. The embung has 211.2 of watershed area, 20 m of water depth and 1.860.000 m3 of water storage capacity to irigate rice field. To promote the unic and strategic embung as an ecotorism object, an ecohydrologic study was conducted in 2008. Ecotourism objects which can be developed around the Sirani embung in Belu Districts are the lake tourism, canoe ride around the embung ; agro-tourism of horticulture plant and fishing pond at the embung downstream; and agroforestry-tourism at the watershed area. Embung ecotourism as an integrated conservation by participation of the local people is needed to develop.

Abstract

Conservation of flora, soil and water resources are very important to manage‘embung’ ecosystem, in West Timor Island. Generally, ‘embung’ watersheds in this area are degraded, and consequently resulted high runoff and erosion rate; and at the same time, ‘embung’ water has not been used efficiently yet. To conserve ‘embung’ ecosystem, three methods can be applied, i.e.: 1). Flora conservation by using priority of local species; 2). Soil conservation by usingvegetative methods; and 3). Water resources conservation in watershed area by combining flora and soil conservation; and increasing water used efficiency by using intermediate technology.

Abstract

To understand the prospect of groundnut development (Arachis hypogaea) for supporting food security in semi arid area, survey and experiment of groundnut varieties were undertaken in Makamenggit Village, East Sumba District, the East Nusa Tenggara Province. Aim of research was to understand natural resources (soil, climate and water) and production potency based on cased study of 6 (six) varieties of groundnut which was cultivated under manure treatment. The six groundnut varieties, i.e. Tupai, Komodo, Zebra, Gajah, Bogor variety and Makamenggit local variety were cultivated in vertisol soil type, organic manure of buffalo feces, irrigation manually from water river in dry season. Parameters of plant height, leave number, and leave cover each individual plant were observed every week, since 5 weeks until 12 weeks after planting. Survey indicated that agro-climate and hydrology of East Sumba was very potential to support groundnut development not only in the rainy season short period (3-4 months), but also in the dry season by utilization of the existence of waterresources (some river and ‘embung-embung’). Result of research showed that six varieties of groundnut had good vegetative growth. The Makamenggit local variety which showed vegetative growth so good performance was potential to promote as a national superior seed. It was obviously that organic manure could increase groundnut vegetative growth (and also reproductive yield) at the vertisol soil type. To develop groundnut cultivation in East Sumba area the utilization of organic manure, cultivation in dry season by irrigation of limited water and seed diversity need to be socialized continuously to the farmers.Keywords: natural resources, prospect, groundnut, food security, east Sumba.

Abstract

Research of plant population density and intercropping of pigeon pie (Cajanus cajan L.) Millsp. and plastic mulching on maize were carried out in field research of R and D Centre for Biology, Indonesian Institute of Sciences, Cibinong from October 2008 to Februari  2009. The aim was to examine the effects of  plant population density and intercropping, as well as mulching to the growth and yield of maize. The resultas showed that population density, intercropping and mulching affected the maize vegetative growth. However, the maize yield was not influenced by population density; but was influenced by intercropping and mulching. Mulching increased maize production, but intercropping by using C. cajan decreased production.

Abstract

The majority of people in Karangan Village work as rice farmers. The majority of farmers use chemical fertilizers, which, in the long term, can reduce soil fertility and rice productivity. In addition, chemical fertilizers are also scarce and prices are increasing. Therefore, the use of organic fertilizers from cow dung waste can be an alternative to reduce dependence on expensive and scarce chemical fertilizers. Organic fertilizers contain organic materials that can increase soil fertility. Community service activities carried out in Karangan Village aim to provide practical solutions to various problems faced by the community, especially in the agricultural sector and community development. The implementation of this program went smoothly, and most of its objectives were achieved. The community gained new knowledge about organic fertilizers and sustainable agricultural techniques. The results of the demonstration in the field showed an increase in crop yields, which encouraged farmers to adopt this technology. In addition, cooperation activities to improve village infrastructure also increased the accessibility of agricultural land, which had a positive impact on the daily productivity of farmers. Masyarakat di Desa Karangan mayoritas bekerja sebagai petani padi. Mayoritas petani menggunakan pupuk kimia yang dalam jangka panjang dapat menurunkan kesuburan tanah dan produktivitas padi. Selain itu, pupuk kimia juga mengalami kelangkaan dan peningkatan harga. Oleh karena itu, penggunaan pupuk organik dari limbah kotoran sapi dapat menjadi alternatif untuk mengurangi ketergantungan pada pupuk kimia yang mahal dan langka. Pupuk organik mengandung bahan organik yang dapat meningkatkan kesuburan tanah. Kegiatan pengabdian yang dilakukan di Desa Karangan bertujuan untuk memberikan solusi praktis bagi berbagai masalah yang dihadapi masyarakat, khususnya dalam sektor pertanian dan pengembangan komunitas. Pelaksanaan program ini berjalan lancar dan sebagian besar tujuannya tercapai. Masyarakat memperoleh pengetahuan baru tentang pupuk organik dan teknik pertanian berkelanjutan. Hasil dari demonstrasi di lapangan menunjukkan peningkatan hasil panen, yang mendorong petani untuk mengadopsi teknologi ini. Selain itu, kegiatan gotong royong untuk memperbaiki infrastruktur desa juga meningkatkan aksesibilitas lahan pertanian, yang berdampak positif pada produktivitas harian para petani.

Abstract

This study evaluates the growth performance and cost-effectiveness of six different seedling media for tomato (Lycopersicum esculentum Mill) cultivation: sand (M1), rice husk charcoal (M2), clay (M3), organic fertilizer (M4), clay-organic fertilizer (M5), and sand-organic fertilizer (M6). The experiment assessed plant height, number of leaves, and number of branches from 7 to 35 days after sowing (DAS). Results showed that media containing organic fertilizer (M4, M5, M6) significantly enhanced all growth parameters compared to non-organic treatments. Among these, M5 (clay-organic fertilizer) achieved the highest values for plant height (34.9 cm), number of leaves (15.5), and number of branches (5.5) at 35 DAS, indicating superior performance. However, cost analysis revealed that M5 also incurred the highest production cost. In contrast, M6 (sand-organic fertilizer) offered a more cost-effective option by providing strong growth performance at a lower cost. These findings highlight the importance of incorporating organic fertilizers into seedling media to improve early growth stages of tomato plants. The use of organic blends, particularly M6, presents a practical and sustainable solution for smallholder farmers aiming to maximize seedling vigor without incurring high input costs, ultimately supporting more efficient and eco-friendly agricultural practices.
