Therefore this study aims to analyze the level of diversity in the measurement of volume of logs in the field between researchers and Technical Personnel for Sustainable Production Forest Management (GANIS-PHPL) inputted in the SI-PUHH Online application. The method used is a quantitative method by developing models mathematical (calculations), which are related to the measurement of logs. The results showed that the Technical Personnel for Sustainable Production Forest Management (GANIS-PHPL) owned by PT. Gema Hutani Lestari is not careful in carrying out its duties and authorities in measuring the correctness of the volume of logs, because there has been an excess volume tolerance of 5.97% of the set tolerance limit of 5%, giving rise to an element of state losses. Thus the performance and role of GANIS-PHPL is deemed necessary for guidance and control related to its duties and authority in terms of measuring and testing the volume of logs, so that the calculation of non-tax state revenue (PNBP) reaches the desired target.

The energy needs of the world including Indonesia continue to increase every year. The most commonly used type of energy sources was dominated by fossil. Fossil energy sources were not environmentally friendly and were predicted to run out in a short period of time. Therefore, the alternative energy sources are needed, such as biomass or better known as bioenergy. The purpose of community service activities in Waai Village, Central Maluku Regency was to increase the community’s knowledge in utilizing biomass as an alternative energy source. The management of agroforestry in Waai village potentially produces many types of non-timber forest products (NTFPs) such as sago (Metroxylon sp.) which has husk as its waste after sago flour had been harvested for food. The implementation of the activity was held from July to August 2023, with activity phases including: social approach to the village government and AM GPM management and continued with visiting the community on Friday 11 August 2023. PKM activities were carried out in two sessions, first, delivery of material and practice of making charcoal briquettes starting from carbonization of sago bark, forming of charcoal briquettes and second, burning of the charcoal briquettes. The community was involved in the practice of making sago bark charcoal briquettes in order to raise their appreciations and increase their understanding of producing charcoal briquettes from sago bark.
