Abstract

Giri Madia Village, Lingsar District, West Lombok Regency is one of the villages prone to landslides. The results of the study showed that around 49.87 Ha of land is classified as a high landslide-prone area. Therefore, mitigation efforts were made to reduce the risk of landslides by utilizing vetiver grass (Chrysopogon zizanioides). This community service activity was carried out through collaboration between the community service team, the village government, and the Giri Madia Village community, from December 2023 to February 2024. The program implementation started from preparation (observation, finding partners, and licensing), implementation (provision of seeds and planting), and monitoring. Coordination with the village government and the local community was carried out through open discussions. The seedling planting activity was carried out by the community service team and the community in three predetermined locations. The monitoring results showed that almost all of the vetiver grass that was planted was able to survive even though it was not watered regularly by the community. Community activities, namely cutting down trees around the vetiver grass planting location, caused more than a third of the total seedlings to die from being hit. In addition, the obstacles that arise are the lack of community participation in grass care such as watering and fertilizing. This can be caused by the lack of public awareness to help care for the fragrant root grass seeds. The community feels that they do not have time to monitor because of their daily activities of earning a living.

Abstract

Dasan Geria Village possesses unique biophysical and sociocultural potential that can be developed into an ecotourism area. Its biophysical attractions include natural landscapes such as several waterfalls, namely Ponjok Waterfall, Bangket Bawo Waterfall, Teburun Nanas Waterfall, and Temburun Bukal Waterfall. The local community’s activities, such as the production of palm sugar (gula semut) and traditional kris-making, also offer distinctive attractions for tourists. However, this initiative is still constrained by challenges related to the development and management of village-based ecotourism, as well as efforts to optimize its potential, benefits, and active community participation. This community service initiative aims to disseminate the concept of ecotourism for implementation in Dasan Geria Village. The application of the ecotourism concept can be initiated through awareness-raising activities, focus group discussions (FGDs), and workshops involving local residents, village authorities, and academics. The people of Dasan Geria hold a positive perception and express agreement with the adoption of the ecotourism concept, while also hoping to receive financial support for its implementation. In applying this concept, consistent and sustainable guidance and assistance for the community in managing and developing ecotourism are essential

Abstract

Gili Gede hosts a vital mangrove ecosystem, essential for the community and protecting coastal areas from large waves. However, increasing development and human activities in and around the mangrove areas threaten their distribution and extent. This study aims to map the spatial distribution, density, and area of mangroves on Gili Gede. Sentinel-2A satellite imagery was utilized with the Normalized Difference Vegetation Index (NDVI) method, and the image data were validated using hemispherical photography. Environmental parameters measured included sediment salinity, temperature, pH, humidity, NPK nutrients, and substrate type. Additional data were gathered on slope, buffer distances, and through semi-structured interviews using purposive sampling. The findings revealed that the mangrove density on Gili Gede is predominantly sparse, covering 15.56 hectares or 77.07% of the total mangrove area. Medium-density mangroves span 3.45 hectares or 17.09%, while dense mangroves occupy the smallest area, 1.18 hectares or 5.84%. Mangroves are distributed across the northern, western, and eastern sides of Gili Gede. The study identified 22 species of mangroves, both true and associated, across 14 families. Environmental factors influencing the distribution, density, and extent of mangroves across three locations include sediment salinity, temperature, pH, humidity, and nutrient content (NPK), as well as substrate type, slope, and anthropogenic influences such as human activities and the proximity of settlements to the mangrove ecosystem.

Abstract

Food problems are a very serious topic globally. This does not only include basic food ingredients such as grains, tubers or other substitute ingredients, but also includes the need for supporting ingredients such as fruit. One of the fruit commodities that many people need is melon (Cucumis melo L.). The availability of melons on the market is currently dominated by farmers' seasonal crops, so their availability is relatively limited outside the season and a surplus during the season, so this has an impact on price stability, both for farmers and consumers. One method that can be offered for this problem is how to carry out cultivation that is not tied to the season by using a greenhouse combined with hydroponic or conventional drip irrigation cultivation methods. The results show that the use of hydroponic methods and drip irrigation can stimulate the growth and especially the development of melon plants. The appearance of flowers in the hydroponic system starts at 2-3 WAP, while in the drip irrigation system it starts at 3-4 WAP. The emergence of productive branches in both methods also takes place from the age of 2 WAP and continues to grow. So from several aspects such as optimal growth, long-term cost efficiency, sustainable agriculture and efficient use of water for agriculture, these two methods can be an effective alternative for melon cultivation.

Abstract

The problem of organic waste in the environment can be overcome by using organic waste bioconversion technology using maggots. This technology produces a by-product in the form of leachate that can be used as Liquid Organic Fertilizer (POC). On the other hand, research on the effect of maggots on the quality and quantity of POC produced has not been widely studied. This study aims to 1). determine the quality of POC based on the concentration of N, P and K; 2). Determine the quantity of POC based on the volume of POC. The method used is an experimental method with the treatment of organic waste conversion using maggots (M1) and without maggots (M0). Each treatment was repeated 4 times. Data were analyzed using the t-independent test with the help of the SPSS version 22 application. The time of this research was carried out in May 2024 - July 2024. The location of the research was carried out at the Lingsar Regional Integrated Waste Processing Site (TPSTR) and the Soil Chemistry Laboratory of the University of Mataram. The results of this study indicate that the quality of liquid organic fertilizer (POC) in M1 is better than M0. The content of N (nitrogen), P (phosphorus) and K (potassium) in M1 were 0.14%, 0.11%, and 0.17% respectively, while M0 was 0.11%, 0.06%, and 0.09% respectively. The t-independent test showed that there was a significant difference between M0 and M1. The content of N, P and K in this study was still below the standard quality values ​​based on the Decree of the Minister of Agriculture of the Republic of Indonesia Number 261/KPTS/SR.310/M/4/2019 concerning Minimum Technical Requirements for Organic Fertilizers, Biological Fertilizers and Soil Improvers.

Abstract

Leaching of nitrogen nutrients in urea fertilizer application is a common problem in vegetable cultivation, including mustard greens (Brassica juncea L.). To address this problem, zeolite is added to the urea fertilizer to maximize the nutrient absorption by plants. This study aims to determine the effect of zeolite addition at various urea fertilizer concentrations on the growth of mustard greens and its effect on the efficiency rate of nutrient adsorption. This research is conducted on March up to May 2023 by using a completely randomized design (CRD) with 8 treatments, namely P0 (control, without urea and without zeolite), P1 (2 gr urea + 200 gr zeolite), P2 (4 gr urea + 200 gr zeolite), P3 (6 gr urea + 200 gr zeolite), P4 (8 gr urea + 200 gr zeolite), P5 (2 gr urea), P6 (4 gr urea), P7 (6 gr urea), and P8 (8 gr urea). Each treatment was repeated three times and put inside a greenhouse. The results showed that the combination of urea and the addition of zeolite to the planting medium gave higher values ​​on leaf area, number of leaves, wet weight and dry weight of mustard plants compared to the treatment of urea fertilizer without zeolite and also the control. The P4 treatment gave the largest leaf area (81.61 cm2) and the largest number of leaves (10.33). The P4 treatment also showed the highest results in wet weight and dry weight, namely 115 grams of wet weight and 9.3 grams of dry weight. The absorption efficiency was higher in the combination treatment of urea fertilizer and the addition of zeolite compared to the treatment of urea fertilizer and without zeolite or with the control. Meanwhile, the highest efficiency was found in the P4 treatment at 56.45%. This finding indicates that the addition of zeolite into the fertilizer can promote the growth of the mustard green.

Abstract

Seagrass is a higher plant from the Anthophyta division that lives below the surface of the air in shallow marine environments. Seagrass ecosystems play a crucial role in carbon sequestration through photosynthesis, which absorbs carbon from the environment. This study aims to estimate carbon stocks in seagrass meadows along the coastal area of Pemenang District, North Lombok. The study was conducted from April to June 2024 using a geographic information system (GIS) approach combined with field observations. The sampling method used a GIS approach to determine the distribution and level of seagrass cover. Seagrass cover levels were classified into three classes: high, medium, and low. Seagrass samples were taken at each cover level and then analyzed in the laboratory to measure biomass and carbon content to estimate carbon stocks. The results showed that the total area of ​​ seagrass beds in Pemenang District reached 685.26 hectares, consisting of eight species, namely Enhalus acoroides, Thalassia hemprichii, Halodule pinifolia, Halodule uninervis, Halophila ovalis, Cymodocea rotundata, Cymodocea serrulata, and Syringodium isoetifolium. Halodule uninervis contributed the highest carbon stock (54.12 gC/m²), followed by Halodule pinifolia (53.22 gC/m²) and Thalassia hemprichii (51.16 gC/m²). The total seagrass carbon stock across the study area was 2.53 tons/Ha, with above-ground biomass at 0.826 tons/Ha and below-ground biomass at 1.7 tons/Ha, amounting to an estimated total of 1,735 tons of carbon. Spatial analysis indicated an even distribution of seagrass meadows along the Pemenang coastline.

Abstract

West Sekotong Village is one of the coastal water areas included in the Gita Nada Aquatic Tourism Park (TWP) area which has a seagrass habitat. Seagrass beds in West Sekotong are threatened due to increased tourism and community activities. This research aims to determine the distribution and extent of seagrass beds on the coast of West Sekotong-TWP Gita Nada. This research uses a remote sensing approach through interpretation of Landsat 8 OLI imagery. This research consists of 2 steps, namely image data processing and supporting data. Image data processing includes several stages, namely image data collection, geometric correction, radiometric correction, image cutting, image composite, image data sharpening, image data interpretation, accuracy testing, area measurement, and final layout. Supporting data was obtained by searching related literature, interviews and surveys of activities that have the potential to have an impact on seagrass ecosystems. The research results show that the distribution of seagrass in West Sekotong-TWP Gita Nada covers the coast of the large island (mainland) and the coast of small islands. The distribution of seagrass on the mainland is found on the coasts of Medang, Tanjung Kelor, Batu Kijuk, Tawun, Labu, Kelapa, Pandanan, Gili Genting, Labuan Petung, Temeran, and Gawah Pudak. In the coastal areas of small islands, seagrass is found on Gili Sudak, Gili Tangkong, Gili Nanggu, Gili Poh, and Gili Lontar. The total area of seagrass beds in West Sekotong is around 144.68 ha. On the mainland coast the area is 118.96 ha (82.2%) and on small islands the area is around 25.72 ha (17.8%). The distribution of seagrass in West Sekotong is influenced by many factors, among which those observed in this research are the type of substrate, the presence of river estuaries, and the use of land and coastal waters.
