Abstract

Mangrove Ecotourism in Tanjung Batu is one of the unique tourist attractions on Lombok Island, featuring a scenic 11-hectare mangrove area with dense vegetation coverage. The site is equipped with several facilities, including a 417-meter wooden bridge, several gazebos, selfie spots, a homestay, and a café. The ecotourism management is handled by the Tourism Awareness Group (Pokdarwis) of Sekotong Tengah Village. This destination is quite popular, with no fewer than 300 tourists visiting each month. However, this area is prone to climate-related disaster risks such as tidal floods, strong winds, high waves, floods, and droughts. Additionally, the ecotourism management has mainly focused on physical aspects and lacks sufficient managerial skills for implementing a sustainable governance system. The proposed solution is to strengthen the Pokdarwis management to improve ecotourism governance, optimizing its potential to deliver greater social, economic, and environmental value while contributing to climate change adaptation and mitigation efforts. The conclusion from the community service activity is that to address these challenges, the community is committed to preserving the mangrove ecosystem, preventing disturbances from both internal and external factors, and managing ecotourism in a way that benefits the surrounding community by reducing climate-related disaster risks. Priority activities include mangrove rehabilitation and enrichment, beach cleanup, monthly management meetings, semi-annual evaluations, and promptly developing plans to strengthen the fishermen's economy through involvement in marine tourism packages

Abstract

Selat Village in West Lombok Regency is known as a bamboo sunshade craft center with abundant bamboo resources. However, the production of bamboo blinds is still done traditionally without the application of preservation technology, making it vulnerable to attacks by destructive organisms such as powder beetles and fungi. Lack of information on effective preservation techniques leads to low product quality and selling value. Therefore, this service activity aims to provide training and assistance to artisan groups in applying simple and environmentally friendly preservation methods. The methods used include an initial survey to understand the condition of the craftsmen, counseling with a Focus Group Discussion (FGD) approach, and the design and implementation of a bamboo preservation tool based on soaking in 5% borax solution. Socialization was conducted to 30 craftsmen from the “Karya Mandiri” group and involved the village and surrounding community. The results of the activity show that the soaking preservation method is more suitable for the needs of craftsmen than the VSD method because the bamboo raw materials used are already in the form of blades. The application of this method can increase the durability of bamboo, speed up the curing process from 1 month to 7-10 days, and increase the selling value of bamboo blinds. The follow-up plan includes periodic evaluation, further training on product finishing and packaging, and promotion through social media to expand the market. This activity contributes to improving the quality and competitiveness of bamboo sunshade products, which is expected to strengthen the economy of the Selat Village community through more effective and sustainable bamboo processing.

Abstract

Nipah Beach is facing challenges of development, economic growth, and high community demand for land, which may negatively impact the sustainability of sea turtles. To mitigate this issue, the ecosystem of Nipah Beach must be appropriately zoned. The goal of beach ecosystem zonation is to allocate areas around the coast to the community and stakeholders based on the sensitivity of sea turtle habitats. This research aims to 1. Analyze the suitability of Nipah Beach in North Lombok Regency as a sea turtle habitat. 2. Design the zonation of the sea turtle conservation area in Nipah Beach, North Lombok Regency. The study uses an observation method, namely collecting data through direct inspection or careful inspection in the field or research location by dividing Nipah Beach into several observation stations. The results are analyzed using scoring techniques and spatial modeling, resulting in a map. Research results show that the suitability level of Nipah Beach as a sea turtle habitat ranges from 15-46 points, with station two having the highest score and station six having the lowest. Stations two and three, and part of station five are prioritized as protection zone areas, station four and part of station five and one as a captive zone area, and the rest as limited-use zones

Abstract

Sugar palm (Arenga pinnata), a multi-purpose tree species (MPTS), has significant ecological and economic benefits. However, the imbalance between the benefits of this plant and its development is a concern. After reaching 50 years of age, the sugar palm tree can no longer reproduce, necessitating the need for cultivation. The primary challenge in cultivating this plant is its hard seed coat. While acidic ingredients have been used to break seed dormancy, natural ingredients are not commonly utilized. This study employed an experimental method with a completely randomized design (CRD). The study design included three factors: maturity level (K), soaking solution treatment (B), and soaking time (L). The parameters assessed in this study were maximum growth potential, germination capacity, leaf length, leaf area, number of leaves, stem diameter, stem length, primary root length, number of roots, and apical shoot length. The results indicate that soaking treatment did not significantly affect the parameters, except for root length. The maturity level treatment also did not significantly impact the parameters. However, K2 seeds (uniform yellow) showed better results in all parameters than other maturity levels, and B3 (100% coconut water) was the soaking solution that yielded positive results

Abstract

Asian palmyra palm (lontar) fronds are a byproduct generated from the asian palmyra palm plant. To add value to these fronds, they can be converted into activated charcoal. This study aims to determine the properties of activated charcoal derived from asian palmyra palm fronds and the effects of activation temperature and chemical concentration on these properties. The activation process was conducted using H3PO4 solution with two concentration variations, 10% and 20%, for 24 hours, and three temperature variations, 600°C, 700°C, and 800°C, each for 60 minutes. The data obtained were analyzed using R software version 4.3.1. The effects of the variation factors in H3PO4 concentration and activation temperature on the yield and characteristics of the activated charcoal were calculated using two-way ANOVA with a 95% confidence level. The properties of the activated charcoal produced met the SNI 06-3730-1995 standard for technical activated charcoal, with yield, moisture content, ash content, volatile matter content, fixed carbon content, and iodine adsorption values of 80.41%, 0.42%, 9.35%, 8.28%, 82.38%, and 668.13 mg/g, respectively. The best properties of activated charcoal were obtained from the activation treatment at 600°C and 20% H3PO4 concentration

Abstract

Climate change affects agroforestry production and community resilience in forest areas. This study aims to: (1) identify vulnerabilities of forest products to climate change; (2) analyze community adaptation strategies; and (3) assess resilience levels of forest-adjacent communities. The research applied descriptive methods via field observations, interviews, and focus group discussions. From 74 residents, random sampling was used (Slovin method, 10% margin of error). Variables included economic, psychological, and social-institutional aspects. Resilience was assessed using a scoring system integrating Reivich & Shatté’s theory and a Likert scale, categorized into five levels: very high to very low. Results show that key vulnerabilities in the Sesaot forest area include harvest failures of major crops (e.g., durian, mangosteen, avocado, rambutan, cacao, coffee), with losses reaching 60–80%. Communities adapted through stratified agroforestry systems and strengthening local institutions. Resilience levels were high overall—economically moderate, but socially and psychologically strong. The study recommends improving economic resilience by reducing crop failure risks, including through the establishment of plant health clinics
