Abstract

This research aims to determine changes in land cover on Gili Meno, Gili Trawangan, and Gili Air as small islands in West Nusa Tenggara Province. The method used in this research is a qualitative descriptive method in comparing land cover changes on each island and also spatial analysis using Google Earth satellite image data in 2013 and 2022. The research results show seven land cover classifications consisting of built-up land, open land, stretches of beach sand, water bodies, plantations, bushes, and mangroves. Based on the analysis of land cover changes in Gili Trawangan, Gili Meno, and Gili Air, a trend of increasing built-up land area for ten years from 2013 to 2022. The most significant increase in built-up land occurred on Gili Trawangan, namely 48.14 Ha. It was followed by Gili Air and Gili Meno, respectively 24.86 ha and 23.71 ha. The driving factor for changes in land cover on Gili Matra is policies from the central, provincial, and regional governments regarding the promotion and establishment of Gili Matra as a tourism destination in NTB Province. Furthermore, this policy impacts the growth of tourists and the number of residents. It causes an increase in the need for tourism-supporting facilities. Therefore, there is a change in land cover, which gradually reduces the area of undeveloped land on Gili Matra.

Abstract

Gili Trawangan, one of the small island clusters in West Nusa Tenggara Province, faces serious problems in managing waste piled up in landfills with the open dumping method by only piling up without any backfilling or other processing. As a result, the Gili Trawangan TPA often experiences fires and explosions, indicating that the waste piles contain gas. This study aims to measure the potential gas stored in the piles of waste at the Gili Trawangan TPA Landfill and determine a strategy for developing methane gas potential as an alternative renewable energy for small islands. GHG emissions from landfills cannot be reduced even with technological advances, but the release of methane into the atmosphere can be significantly reduced by collecting methane gas. The methane gas content of waste at the Gili Trawangan TPA can be concluded that the peak of total methane gas production will occur in 2024, reaching a maximum of 192.23 MWh/year in the form of electrical energy and the form of gas as much as 216 kg of LPG/day. The potential energy figures obtained come from the potential of methane gas deposits in the same year of 172,100 m3/year based on modeling results using LandGEM software. Therefore, the potential of methane gas stored in waste piles can be used as an alternative energy source or as a starting point for policy-making for managing organic waste that triggers the formation of methane gas.

Abstract

Makalah ini mendiskusikan hasil kajian kualitatif peran kolaborasi dalam beradaptasi terhadap perubahan iklim di pulau-pulau kecil. Ketergantungan pulau-pulau kecil seperti Gili Trawangan (GT) pada industri pariwisata telah menyebabkan tekanan (stress) dan gangguan (perturbation) yang berdampak pada keseimbangan sistim sosial-ekologi di GT. Jika ekosistim pulau-pulau kecil terus mengalami degradasi maka kemampuannya untuk menyerap karbon semakin rendah sehingga tidak mampu mengurangi gas rumah kaca (GRK) yang terakumulasi di atmosfer. Upaya pengurangan emisi GRK dapat dilakukan dengan mempertahankan stok karbon yang ada di dalam tanah maupun di atas permukaan tanah dengan meningkatkan serapan melalui berbagai program reforestrasi. Kegiatan Pengabdian Masyarakat, yang dilaksanakan selama bulan Juli dan Agustus 2021, ditujukan untuk meningkatkan kapasitas kelompok kolaboratif masyarakat dalam beradaptasi terhadap perubahan iklim di pulau-pulau kecil, khususnya GT. Sedangkan secara khusus kegiatan ini dimaksudkan sebagai upaya penguatan kelompok kolaboratif melalui peningkatan pengetahuan, keterampilan, teknologi quantifikasi cadangan karbon di dalam tanah maupun di permukaan tanah, dengan memberdayakan sumberdaya lokal sehingga diharapkan mampu beradaptasi terhadap perubahan iklim. Proses penguatan kapasitas kolaborasi masyarakat GT dilakukan dengan pendekatan action learning untuk memastikan luaran yang direncanakan bisa dicapai:Pengetahuan kelompok kolaboratif masyakarat GT tentang konsep dan prinsip sekuestrasi karbon dan dampaknya terhadap kerusakan lingkungan semakin meningkat; ketrampilan tehnik mengestimasi jumlah cadangan karbon dalam tanah dan permukaan tanah meningkat; dan demplot sebagai laboratorium pelatihan lapangan bagi kelompok masyarakat dari desa-desa lain di KLU dapat diberdayakan.

Abstract

Usaha tani cabai merah di Kecamatan Sembalun, Lombok Timur layak untuk dikembangkan lebih lanjut dari segi finansial. Lombok Timur juga menjadi sentra aktivitas cabai Indonesia, karena memberikan kontribusi terhadap perekonomian nasional (Syahrul, 2023). Dibanding tanaman lain, cabai sangat menjanjikan karena dari hasil panen 60 ton per ha dapat menghasilkan Rp30 juta per panen. Selain itu cabai bisa ditanam dan dipanen empat kali dalam satu tahun. Selain itu, Pemerintah juga telah bermitra dengan 11 Champion Cabai yang tersebar di 10 kabupaten di Indonesia, salah satunya di Kabupaten Lombok Timur. Komitmen Champion Cabai pada tahun 2023 untuk Kabupaten Lombok Timur agar dapat menyediakan lahan kurang lebih 200 hektar. Tentunya komitmen ini mendapat sambutan baik dari Ditjen Hortikultura untuk memfasilitasi saprodi berupa pupuk. Untuk meningkatkan produktivitas produk dapat memanfaatkan teknologi pemupukan dalam budidaya cabai yang ramah lingkungan. Pupuk organik merupakan pupuk yang ramah lingkungan dan dapat mengembalikan kesuburan tanah yang telah menurun. Menurut (Musnawar, 2007), pupuk organik menjadi pilihan untuk memaksimalkan produksi pertanian dan juga menjadikan lahan pertanian sehat. Permasalahan dan kendala yang sering dialami masyarakat di produktivitas tanaman cabai per hektarnya masih dibawah standar. Hal ini dipengaruhi oleh kurangnya kemampuan petani dalam melakukan evaluasi dari setiap kendala yang dihadapi khususnya pada saat melakukan budidaya cabai merah. Target yang ingin dicapai dari kegiatan pengabdian kepada masyarakat ini adalah meningkatnya kemampuan dari petani untuk melakukan budidaya cabai merah melalui pemupukan organik.

Abstract

Community service activities were carried out at the Sugih Hati Farmers Group which develops various seasonal horticultural crops (i.e. chili, tomato, watermelon and melon) on Vertisols land in Kawo Village, Pujut District, Central Lombok. This activity aims to popularize appropriate technology in the form of biochar-based organic fertilizers to increase soil fertility and horticultural crop productivity. The use of biochar in this agricultural land is an alternative solution to improve soil quality, namely by increasing the organic matter content of the soil, water and nutrient efficiency, and reducing soil acidity due to the use of high-analysis inorganic fertilizers. Dissemination activities have been carried out using participatory methods by involving members of the farmer groups and agricultural entrepreneurs in focused discussion activities. The results of the dissemination process reported that farmers played an active role in expressing various problems and challenges faced in farming, namely land management problems, especially fertilizer management, management of planting systems/cropping patterns and control of plant pests and diseases. Thus, they agreed to utilize biochar in the planting system. The discussion also discussed the phenomenon of climate change as one of the obstacles to horticultural crop cultivation, especially drought. Farmers are very enthusiastic in understanding the business prospects of horticultural crops, especially to meet the demand of hotels, restaurants and other tourism activities particularly in the Mandalika Special Economic Zone (MSEZ), well known as KEK Mandalika.

Abstract

Rice bean is a group of beans that are rich in carbohydrates, proteins and fats. This plant is resistant to pests and diseases, as well as the broad adaptability. This study aims to obtain an efficient fertilization pattern on rice bean cultivation in dry land. The treatments consisted of 9 fertilization patterns which were RP0: no fertilizer (control); RP1: 100% recommendation fertilizer (50 kg Urea and 100 kg SP-36 ha-1); RP2: 5 Mg ha-1 manure plus 50% recommendation fertilizer; RP3: RP2 plus MVA; RP4: 5 Mg ha-1 Crotalaria sp compost plus 50% recommendation fertilizer; RP5: RP4 plus VAM; RP6: 2.5 t ha-1 manure, 2.5 Mg ha-1 Crotalaria sp compost plus 50% recommendation fertilizer; RP7: 1.5 Mg ha-1 manure, 1 Mg ha-1 Crotalaria sp compost plus 50% recommendation fertilizer; RP8: RP7 plus MVA. Fertilization treatments were arranged in RCBD and each treatment was repeated 3 times. The fertilization treatments had no significant effect on NUE. Productivity of rice bean in RP3 and RP5 reached 3.75 Mg ha-1, in RP2 and RP4 achieved 2.64 Mg ha-1, and in the control treatment reached 1.94 Mg ha-1. Carbohydrate content in seeds increased by 20% in the fertilization treatments compared to the control. Protein and anthocyanin content in all treatments were not significantly different. The combination of 5 Mg organic fertilizer (manure and / or Crotalaria compost), 50% recommendation fertilizer plus MVA was an efficient fertilization pattern to improve P fertilizer uptake efficiency (PUE), productivity and quality of rice bean crop in dry land.

Abstract

Gili Meno is a small island located to the north of Lombok Island which is included in a conservation area with high potential as a tourist destination. As a tourist destination, there has been a conversion of green land into hotels and other tourist facilities which has led to changes in land use patterns. In order to reduce the increase in earth's surface temperature due to green house gas (GHG) emissions, especially CO2, CO2 mitigation efforts are needed by squesting carbon into the soil. Research on soil carbon stocks on Gili Meno has been carried out using descriptive methods with survey techniques, namely by taking soil samples in several types of land cover at two depths, namely 0-10 cm and 10-20 cm. The soil samples taken were used for analysis of C-Organic and some physical characteristics of the soil. Based on the data obtained, mangrove land cover has the largest potential carbon reserves, namely 89.36 tons.ha-1, then followed by shrub land cover, then coconut plantations, and finally open land and settlements with values respectively 57.50 ton.ha-1, 44.11 ton.ha-1, and 36.15 ton.ha-1. The high soil carbon reserves in the mangrove ecosystem compared to other land covers reflect that the carbon storage potential of mangrove land covers is better compared to other land cover types. Thus, for long-term land management, the sustainability of mengrove plants must be maintained.
