Mitigasi Longsor Dengan Penataan dan Peningkatan Kemampuan Kawasan Perbukitan Pada by Pass BIL-MANDALIKA Sebagai Infrastruktur Penunjang Kawasan Ekonomi Khusus (KEK) Mandalika Lombok : Landslide Mitigation by Structuring and Increasing the Capability of Hill Areas on By Pass BIL-MANDALIKA as Supporting Infrastructure for The KEK Mandalika, Lombo

One of the tourist destinations in Lombok, West Nusa Tenggara is the Special Economic Zone Mandalika (KEK Mandalika), a coastal tourism area with various supporting infrastructures on an international scale covering an area of 1,035.67 hectares. The pace of development brings environmental impacts, especially the morphology of the land in the form of mountains and hills is exposed by the conversion of land functions from proteced forest to agricultural areas without the application of land conservation methods. Bypass BIL-KEK Mandalika as the main connecting road for this tourism area is 17.2 km long flanked by hills with a slope of >30o and almost all hilly areas have been converted into agricultural areas. In this area there is minimal standing vegetation accompanied by unstable physical conditions, making all hilly areas on the BIL-KEK Madalika bypass classified as a Very High Erosion Hazard Level which reaches > 560 tons/ha/year which triggers more potential hazards. big like landslides and floods. Various steps have been taken, such as: 1) Integration of porang (Amorphopallus) and standing vegetation (canopy) applied in hilly areas in the Bypass BIL-KEK Mandalika area; 2) Emphasizing and preventing the conversion of buffer zones; 3) Rehabilitation of the Bypass BIL-KEK Mandalika Hills Area

Kajian Biofisik Lahan Untuk Tanaman Porang Sebagai Anasir Konservasi Pada Sistem Agroforestri Di Pulau Lombok

Agricultural land in North Lombok is dominated by a typology of sub-optimal land, physically, chemically and biologically. These properties make it vulnerable to degradation. In such land, agroforestry system is highly recommended, where the porang plant can be included as a component. Nowdays, porang is gaining popularity as a commodity with economic value, and is suitable as an intercropping plant. It is easy to grow on almost all types of soil, and is resistant to shade, making it adaptive to agroforestry systems as non-timber under standing plants in community forest systems. It is believed that this will provide multiple benefits economicly and environmentaly, if it accompanied by the principles of soil and water conservation. The role of porang as a conservative agent has been investigated through a scientific approach as the basis for the domistication of porang in agroforestry systems. The results showed that agroforestry with porang could help improve the stability of the soil aggregates as indicated by the soil aggregate stability index 59 which means rather stable. Soil moisture of wilting point in agroforestry system with porang increased from 3.0% (without porang) to 5.4%. In addition, the soil organic matter content increased to 3.94% (quite high) on the system with porang because the stems and leaves of porang plant are quickly weathered. The ground cover is relatively tight, so it can prevent soil erosion. Porang also play a role in increasing water infiltration due to the presence of porang’s roots and tubers. Thus the domistication of porang fulfills the requirements as an agent of soil conservation, as non-timber plant in the agroforestry system, if it is cultivated according to the principles of soil and water conservation on the typology of sub-optimal land in North Lombok.

Pengenalan Teknologi Penyediaan Bibit Berkualitas Multi Entris Untuk Percepatan Perolehan Produksi Tinggi Tanaman Jarak Pagar Dalam Rangka Pengembangan Desa Mandiri Energi Ramah Lingkungan

Jatropha plants in the Amor-Amor area, North Lombok Regency, West Nusa Tenggara have long been growing and developing as land boundaries, yards, and village roads, but are not used as alternative energy sources, then they do not provide results or income. This is due to limited ability to apply technology for create more profitable. On the other side, utilization of irrigation facilities that have been provided in the form of bore-wells is very rarely used in connection with expensive operational costs, especially on fuel components. Extension activities and demonstrations in the provision of multi-entry Jatropha seedlings with the aim of increasing the knowledge of farmer group members for better implementation Jatropha cultivation technology. The results show that the counseling and demonstration provided was quite capable of arousing interest and the need for farmers to adopt introduced technology. Members of the Telaga Valley Farmers Group were at the trying stage and if assistance is continued, farmers will reach the adoption phase, therefore it takes a long time for technology transformation to form an Energy Independent Villag
