Titi or Gmelina moluccana is a type of the Lamiaceae family that grows in Maluku. Although this species is local, there is still very little information about its growth. This study aims to determine the growth of this species from planting in the field until the sixth year, environmental factors that affect its growth. Data collected in the form of plant height and diameter, air temperature, humidity, soil pH, soil moisture, sunlight intensity. Environmental factors are then related to plant height and diameter to determine environmental factors that affect the growth of these plants through multiple linear regression equations. Besides, the mean annual  increment and the current annual increment is also calculated to determine the cycle of this plant. Based on the results of research, Titi plants up to the sixth year have an men annual increment and the current annual increment is 0.99 meters/year and 1.46 meters for height and 1.62 cm/year and 2.50 cm for diameter. Until the sixth year this species has not entered the techniquecycle, while for woodworking purposes, this species can be harvested at the age of 24.5 years. Environmental factors that affect the growth of Titi are soil pH and soil moisture.

Salah satu hasil hutan non kayu adalah serangga berguna lebah madu diantaranya Lebah Trigona sp. Trigona sp. dikategorikan sebagai kelompok serangga sosial yang memiliki banyak manfaat, dan berkhasiat untuk kesehatan. Sarang lebah Trigona sp di Desa Suli sangat banyak ditemukan pada lubang-lubang goa, kusen-kusen pintu atau jendela milik masyarakat, sehingga untuk memanen madu atau propolis dari lebah Trigona sp, membutuhkan anggaran yang besar karena kusen pintu atau jendela harus dibongkar. Pengabdian ini dilakukan di desa Suli, berupa penyuluhan tentang beternak lebah tanpa sengat (Trigona sp) di dalam sarang ruas bamboo, dengan tujuan untuk menambah wawasan dan pengetahuan masyarakat tentang teknik budidaya lebah Trigon sp menggunakan sarang bambu sebagai tempat berkembang biak atau media yang mudah didapat dengan biaya yang murah. Teknik budidaya lebah Trigona sp di dalam bambu dimulai dari pembuatan rumah lebah dari bambu, menggergaji bambu dan membuat cincin, memindahkan lebah Trigona sp ke dalam bambu, kemudian bambu ditutup dengan selotip dan bambu siap diletakkan pada tempat yang sudah ditentukan atau disekitar tempat tinggal. Produk yang dihasilkan masih berupa produk mentah, sebab madu, propolis dan roti lebah masih bercampur. Agar siap dipasarkan, maka ketiganya harus dipisahkan.

Efforts to save the forest should be  done to avoid forest damage by pests. This aim of this study  was determine the type of pest and area of attack on the resin stand (Agathis alba) in conservation forest Sirimau, Maluku Province by used of survey method. The results of the study found that pests that destroy dammar in conservation forest Sirimau are leaf-eating pest (Valanga nigricormis) and stem borer (Massicus scapulatus). The damage caused by Valanga nigricormis at the seedling level  was 92%, the weaning level  was 72%, and the pole level was 64%. The damage caused by Massicus scapulatus at the tree level was 60%. The extent of attack of both types of pests was categorized as heavy to very heavy.

This study aimed to determine changes in litter biomass and the effect of changes in litter biomass on carbon stock changes in Permanent Sample Plots of primary and secondary forest in the Protection Forest of Soya Village, Ambon City, for three years of measurement. This study used a sampling method with harvesting/collection and using laboratory analysis, where the working procedure used the SNI: 7724 guidelines. The data taken includes the water content of litter, total wet weight, dry weight of the sample, and wet weight of the sample to calculate the range of biomass or organic matter and carbon content of litter organic matter. The results showed that the average value of water content in both primary and secondary forests decreased. The depletion degree was higher in the first year than the second and third year. The biomass content of litter in primary forests decreased from year to year for three years of measurement. It causes a decrease in the carbon content in the primary forest. In contrast, the biomass content in secondary forests increased from year to year and increased carbon content from year to year for three years of measurement.

Titi (Gmelina moluccana) is one of the native species that grow in Maluku. The information such as the growth and development of this species was still lacking. The purpose of this study was to determine the development of Titi plants at six years after planting. This research was studied lasted for six years and the measured data were plant height and diameter for six years. The method used is to analyze the development of the Titi plant based on the growth phase of the tree.  The results showed that Titi plants after six years of planting had been in the growth phase of saplings or young trees and this type was species that in catagory fast growing because it almost reaches its economic cycle. These plants can be used for forest cultivation and industrial raw materials.
