Biopelet adalah bahan bakar padat yang dihasilkan dari pengempaan biomassa menjadi sumber energi bakar alternatif. Limbah padatan kayu putih dan gondorukem berpotensi untuk biopelet. Kualitas pembakaran biopelet lebih baik dari pembakaran biomassa secara langsung. Tujuan penelitian ini adalah untuk mempelajari ukuran serbuk dan suhu pengempaan yang optimal untuk menghasilkan biopelet berkualitas terbaik dan ramah lingkungan. Limbah padat kayu putih dan gondorukem dicampur dan dijadikan serbuk, dengan ukuran penyaringan 20 mesh, 40 mesh, 60 mesh, dan 80 mesh. Dari masing-masing ukuran serbuk dilakukan pencampuran sebanyak 30 g untuk dicetak dengan perbandingan 70% limbah padat kayu putih dan 30% gondorukem. Pencetakan biopelet dilakukan dengan menggunakan mesin kempa hidrolik bertekanan 526,48 kg/cm2 dengan suhu pencetakan yang diinginkan antara lain 120, 150, 180, 200, 230, dan 260°C. Hasil penelitian menunjukan biopelet yang dibuat dari serbuk berukuran 40 mesh dan suhu pengempaan 230°C menghasilkan biopelet dengan kualitas terbaik. Sifat fisik biopelet yang dihasilkan dari ukuran serbuk 40 mesh dan suhu pencetakan 230°C yaitu kadar air 1,905% ; kadar abu 3,955%; kandungan zat terbang 72,189%; kadar karbon terikat 21,949%; nilai kalor 5097,5 kkal/kg; dan keteguhan tekan 53,746 kgf/cm2.

Manusela National Park borders several villages to the south. The proximity of the village location to the National Park is an opportunity to improve the family economy based on Non-Timber Forest Products (NTFPs) through cultivating Trigona sp bees. The aim of Community Service activities is to educate and train the community of bee farming groups to provide stock. Community Service Activities were carried out in collaboration with the Manusela National Park Office, in Moso village, Central Maluku Regency on 21-25 November 2023. The communities who are stakeholders in this activity are honey farmer groups from 3 villages, namely: Moso village, Teluti Baru and Hattu. PKM activity participants are involved in all series of activities starting from delivering materials for making stups to placing stups. The resulting stup was 10 units and 3 units were placed in each village and 1 stup unit was placed around the location where the stup was made.

In recent years, a transition towards renewable energy sources has begun to reduce fossil energy usage. One alternative renewable energy source is biopellets, which have gained public interest as an environmentally friendly fuel. Biopellets are a type of renewable energy derived from biomass, which, if it emits too much carbon, can lead to pollution. Carbon emissions are also related to combustion efficiency, as complete combustion can help reduce carbon emissions. This study aims to determine combustion emissions and combustion efficiency of biopellets made from eucalyptus solid waste with the addition of rosin to optimize the use of raw materials as renewable energy. The study employs an experimental laboratory approach with a factorial design to test the impact of sulfur, chlorine, and nitrogen content on the combustion efficiency of biopellets made from eucalyptus waste and rosin. Results indicate that the sulfur and chlorine content remain above the French standard (ITEBE), at 0.31% and 1.12%, respectively, while nitrogen content is below the standard at 0.48%. The resulting combustion efficiency ranges between 9.569% and 9.701%.

This research aims to assess the role of agroforestry in farmers' income and environmental sustainability in Haruku Village. The study used a purposive sampling method, selecting 20 respondents who apply the dusung agroforestry system in Haruku Village. Interviews and observations were conducted to collect primary data, while secondary data were obtained from the Haruku village government and other literature sources. The results indicate that there are 29 types of plants, including vegetables, fruits, tubers, and timber plants, commonly cultivated by the community in Haruku Village. Through the implementation of the agroforestry system, farmers' income is higher than non-agroforestry income. Agroforestry practices also contribute to environmental sustainability by reducing climate change impacts and decreasing the use of inorganic fertilizers among farmers.

Karendang is one of the thorny shrubs that has a dark red color and has a slightly sour taste. Karendang has a high moisture content, so it will quickly decay, so further processing into jam is needed. Jam is one of the semi-wet foods made from a mixture of sugar. The purpose of this study was to determine the concentration of sugar in making karendang jam against the sensory characteristics of karendang jam. The design used is a Complete Random Design (RAL) with a treatment of adding sugar concentration consisting of 4 levels, namely the addition of sugar 25%, 50%, 75% and 100% and repeated 3 times. Hedonic observations made consisting of color, taste, aroma, texture and smearing power were carried out by 30 rather trained panelists. The results showed that the G2 treatment (50% added sugar) had the color, taste, aroma, texture and spreadability preferred by the panelists and was the best treatment for making karendang jam.

Non-Timber Forest Products (NTFPs) play a vital role in supporting the livelihoods of rural communities, particularly those living in or around forested areas. This study aims to assess the economic value of NTFPs and their contribution to sustainable livelihoods in Haruku Village, Central Maluku Regency. Utilizing a mixed-methods approach that combines household surveys, key informant interviews, and direct observation, the research evaluates the income derived from various types of NTFPs and examines their role in the economic resilience and sustainability of local households. The results show that income generated from NTFPs reached IDR 1,393,010,000, while income from non-NTFP sources amounted to IDR 1,256,808,450, resulting in a total household income of IDR 2,649,818,450. The contribution of NTFPs to the total income of Haruku Village households is categorized as moderate, accounting for 52.57%. Among the various NTFPs, three main products were found to contribute significantly to household income: cloves (47.02%), sago (17.69%), and durian (10.97%). This study highlights the importance of integrating NTFPs into local and regional development strategies to enhance economic sustainability and ecological balance in forest-dependent communities.

Fuel is one of the important factors in household industries. However, in recent years, there has been an energy crisis, leading to fuel shortages. The government's effort to address this issue is by utilizing biomass waste to produce bio-pellets, which are environmentally friendly fuels. The community of Ureng village is closely connected to forest products, but they have not yet been able to utilize forest resources optimally. Therefore, the aim of this activity is to introduce and socialize bio-pellets made from biomass waste of the mixed sawdust. The method used in this activity includes raising awareness about the benefits of bio-pellets and providing a simulation on how to produce bio-pellets. The results achieved were the success of the activity, shown by the increase in the village community’s knowledge about the benefits of bio-pellets, with pre-test and post-test scores of 20% and 80%, respectively. Additionally, the community showed great enthusiasm for bio-pellet production, which is expected to reduce the use of fossil energy, decrease biomass waste, and increase village income.

Carbon reserves in forests play a crucial role in climate change mitigation and the preservation of global ecosystems. Forests act as primary absorbers of carbon dioxide (CO2) from the atmosphere, storing carbon in the biomass of trees, soil, and leaf litter. This community service aims to provide understanding and education to the public about carbon storage, factors influencing storage capacity, and the implications of sustainable forest management. The methodology used includes direct measurement of carbon reserves in various forest types and the analysis of secondary data from scientific literature. Survey results indicate that the village forest of Wapkalit still has significant potential, emphasizing the need for community awareness to continue managing and preserving the forest. Socialization conducted through the FGD (Focus Group Discussion) method can directly impart knowledge to the community.
