Vetiver grass (Chrysopogon zizanioides) is a large grass plant and has long and strong roots. Vetiver grass has an important role in minimizing erosion, soil conservation and controlling landslides. The introduction of vetiver grass as a plant to resist erosion and landslides in steep and sandy areas can have a positive impact. However, public knowledge about vetiver grass is still lacking, while the community's need, especially for handling landslides, is very high. The main purpose of planting vetiver grass is to use it as cultivation and from an economic perspective it can help as a new business opportunity for the residents of Giri Madia Village. The method used in writing this article is a qualitative approach with the aim of placing greater emphasis on aspects of an in-depth understanding of the use of vetiver as an opportunity that can be used as a business for the people of Giri Madia Village. The results obtained from this activity are helping residents to increase their knowledge of vetiver grass plants which have economic benefits and can prevent landslides. The existence of demonstration plots in two hamlets in Giri Madia village has resulted in knowledge and awareness regarding landslide disaster mitigation. The workshop is able to provide knowledge about how to prepare seeds, then provide planting media, materials and how to plant and care for vetiver grass so that it can grow and reproduce in order to prevent landslides. The planting was in two hamlets in Giri Madia Village, namely Leong and Leong Jaya Hamlets, because the Village Head recommended that we focus on these two hamlets. The role of the community in Leong Hamlet is active, but their role in maintaining vetiver grass is decreasing day by day because they are busy working. For participation in Leong Jaya Hamlet, it was felt that there was not enough attention paid to caring for the demonstration plots and seedling houses, there were several factors, namely that they had jobs as workers on plantations. So the solution is that the hamlet head must collaborate with the local community for the maintenance and upkeep of the demonstration plot and seedling house.

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

The coastal area of Gili Trawangan, a prominent tourism destination, is facing increasing ecological pressure due to intensified tourism activities and population growth. This study aims to analyze the distribution and composition of macro debris along the coast of Gili Trawangan, North Lombok Regency. This study used transect and quadrat methods, as well as marine debris classifications according to NOAA and Tangavoa Blue. The results showed that the highest amount of waste was plastic (71%), followed by glass (13%), and ceramics (8%). The highest waste distribution was found at the port (62kg) and tourist areas (30%). These findings highlight that inadequate waste management and low public awareness significantly contribute to coastal pollution. Therefore, an integrated waste management strategy and increased public participation are urgently needed to preserve the marine ecosystem of Gili Trawangan.

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.

The high level of construction and community activities at Kecinan Beach can affect the condition of the coral reef ecosystem. The health condition of the coral reef ecosystem can be assessed by the percentage of live coral cover within the ecosystem. North Lombok is one of the regencies on the island of Lombok that has experienced coral reef ecosystem damage, with this regency having the lowest percentage of live coral cover compared to other regencies. This study aims to determine the diversity of coral reef lifeform types and assess the health status of coral reefs at Kecinan Beach, North Lombok Regency. Data on coral reef lifeform types were observed using Coral Finder 2.0 Indo Pacific. Data collection was conducted using the UPT (Underwater Photo Transect) method at two different depths: 1-5 meters and 6-10 meters. The research results indicate that the coral reef ecosystem at Kecinan Beach is in poor condition. The percentage of live coral cover at depths of 1-5 meters is 3,58%, and at depths of 6-10 meters is 0,90%. There is ten types of coral reef lifeforms were found distributed across both depths: Acropora branching, Acropora tabulate, coral branching, encrusting, foliose, heliopora, massive, millepora, mushroom, and submissive. Diversity, evenness, and dominance indexs shows even distribution of lifeforms with no dominant species in the coral reef ecosystem at Kecinan Beach, North Lombok.

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.

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.

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.
