STRATEGI PENGENDALIAN ALIH FUNGSI LAHAN PERTANIAN DI DESA PANDAK GEDE KABUPATEN TABANAN
Get PDFAbstract
The Tabanan District Spatial Plan 2012-2032 states that Pandak Gede Village has a role as an environmental center that functions as the center of a residential area that serves the surrounding rural areas. The increase in population in Pandak Gede Village has caused changes in the number and distribution of settlement areas. The reduced area of agricultural land can be an indication of the conversion of agricultural land to non-agricultural land. Given these indications, research is needed to find out how the conditions of land use change in Pandak Gede Village are seen from the social, economic, cultural aspects. Are there developments that are not in accordance with the Spatial Plan for Tabanan Regency 2012-2032, is there any indication of the conversion of agricultural land in Pandak Gede Village and how alternative strategies can be taken to minimize the mismatch of regional development against the Tabanan District Spatial Plan 2012-2032. The method used in this research is the mix method. The analysis included: socioeconomic analysis, socio-cultural analysis, regional development analysis, land use suitability analysis, and analysis of agricultural land use control strategies. The results showed an indication of the conversion of agricultural land by 18.71 hectares into residential and non-agricultural land. Alternative strategies that can be done are facilitative, reeducative, persuasive and power strategies to the government, to Pandak Gede Village, to community owners and buyers of land, to environmentalists, to further research and education.

Abundance and composition of plastic waste in Baturusa watershed of Bangka Belitung Islands Province
Get PDFThe usage of plastic has been increasing from year to year for its durable, lightweight, sturdy, easy to form, and low cost production, so that plastic becomes a popular material. Plastics have affinities with persistent organic pollutant such as PCB, DDT, PAH and phthalates that can damage the ecosystem as well as harm to human. In this study plastic wastes were collected using nets in seven stations along Baturusa watershed, sorted based on its composing resin (RIC), then measured the abundance and the density rate on each station. 36% of the collected plastic wastes are Polypropylene (02), and 24% are LDPE (04). The highest density rate of collected plastic wastes was found on Mabet river (1.36 x 102 items/m3), followed by Baturusa river, and Rangkui river estuary. These three stations are located near the settlements so that the source of the plastic wastes comes from domestic activities. The variety of waste management showed a significant impact to the amount of plastic wastes on waters. One of the plastic waste management for the settlements is to carry out 3R (reduce, reuse, recycle), such as waste bank programs and implement EPR (extended producer responsibility) programme. The successfulness of this programme can only be achieved by the active participation of the waste bank customers and the implementation of 3R principle in daily life

Get PDFHorseshoe crabs are living fossils found in Indonesia. This study examined the food habit of horseshoe crabs (Carcinoscorpius rotundicauda and Tachypleus gigas) collected from Balikpapan coastal waters, East Kalimantan. Horseshoe crabs were captured using gill nets and picked by hand along the Balikpapan coast. The width of the prosoma and the body weight of each individual were measured, and the gut contents were analysed to determine the preponderance index, food niche breadth, and niche overlap. Carcinoscorpius rotundicauda prosoma widths ranged from 4.1 to 15.4 cm and those of Tachypleus gigas ranged from 2.8 to 24 cm. Eight food items were found in the gut of the horseshoe crabs, namely: bivalves, gastropods, scaphopoda, polychaetes, echinoderms, crustaceans, leaf litter and others. Based on the preponderance index, gastropods were the main food item of the two horseshoe crab species. In accordance to the food composition the horseshoe crabs inhabiting Balikpapan coastal waters are categorized as benthivores

Community based Management Sasi Laut Folley and Dynamics of Community Based Management
No full textAbstrak: Indonesia semakin mengalami penurunan kuantitas dan kualitas sumber daya alam. Penyebab utama dikarenakan pemanfaatan berlebih dan merusak tanpa tanggung jawab dari beberapa pihak. Berbagai langkah mitigasi yang ditempuh cenderung menguntungkan satu pihak. Diperlukan model pengelolaan yang tepat dan bermanfaat bagi semua pihak. Pengelolaan berbasis masyarakat (PBM) seperti pengelolaan Sasi Laut di Kampung Folley, Papua Barat merupakan salah satu model yang dinilai tepat dilakukan. Sasi sebagai tradisi, diduga mengalami banyak perubahan. Tujuan penelitian ini untuk menganalisis dinamika pengelolaan Sasi Laut Kampung Folley dan dampaknya terhadap penguatan pengelolaan. Hasil penelitian menunjukan terjadi dinamika pengelolaan yang setidaknya melibatkan lima momentum perubahan, yaitu masa pembentukan kampung, intervensi peran agama, introduksi teknologi, keterlibatan pihak eksternal dan penetapan regulasi Kawasan Konservasi Perairan. Unsur pengelolaan yang berubah yaitu batas wilayah, peraturan, pemegang otoritas, hak, sanksi, dan monitoring yang disebabkan faktor internal dan eksternal. Dinamika pengelolaan yang terjadi mengarah pada penguatan pengelolaan Sasi Laut.Abstract: Indonesia is currently experiencing a decline in the quantity and quality of natural resources. The main cause is due to excessive use of natural resources and destructive behavior without responsibility of various parties. Mitigation measures that have been taken only benefit certain parties. An appropriate management model that is beneficial for all parties is needed. Community based management (CBM) such as the management of Sasi Laut in Kampung Folley, West Papua is one of the models considered appropriate to apply. Sasi as a tradition, is thought to undergo many changes. The aim of this study is to analyze the dynamics of the management of Kampung Folley Sea Sasi and its impact on strengthening management. The results of this study indicate that there is a management dynamics that involves five momentum changes, namely the formation of the village, the intervention of the role of religion, the introduction of technology, the involvement of external parties and the establishment of regulations for Water Conservation Area. The management elements that have changed are territorial boundaries, regulations, authority holders, rights, sanctions, and monitoring due to internal and external factors. The management dynamics that occur are leading to the strengthening of Sasi Laut management

Aplikasi kleinano dari tuf volkan Gunung Salak Indonesia sebagai adsorben alami kontaminan anionik: Fosfat perairan
Get PDFIndonesia is rich with volcanic tuff-derived Andisols that contain variable charged minerals. This research was aimed at to extract nanoclays (diameter <200 nm) from volcanic tuffs, and to evaluate their potential as natural adsorbent of phosphate as contaminant in waters. Volcanic tuffs were taken from the 3rd (tv3) and 4th(tv4) layers of an Andisol profile at the foot slope of Salak Mountain Indonesia using dispersion-ultrasonication-centrifugation-dialysis separation procedure. By dispersing the materials in an acid condition (pH 4.0) followed with ultrasonication, it could be separated positively-charged nanoclays (nc3 and nc4) from the negative ones. The separated nanoclays were then purified using centrifugation and membrane dialysis techniques. Potential of the extracted nanoclays as natural phosphate adsorbent was evaluated by characterizing their adsorption maxima (b values) according to the Langmuir isothermal adsorption model. It could be extracted 2.82 mg nc3/g tv3 and 4.29 mg nc4/g tv4. The b values of nc3 at 12, 24, and 48 hours equilibration time (76.48, 92.10, and 117.54 mg P/g nc3) were higher than those of nc4 (50.17, 59.52, and 71.99 mg P/g nc4). The most effective equilibration-time was 48 hours. The extracted nanoclays were considered prospective as natural adsorbent for removal phosphate contaminant in water
