Non-timber forest product commodities in Gunung Silanu Village are cashew, turmeric, candlenut, coffee, cocoa, ginger, and galangal. Among these commodities, cashew and turmeric are the most developed commodities. However, this study is focused on the cashew (Anacardium occidantale). Cashew seed processing in Gunung Silanu Village only reaches into the drying stage, even though there was a peeling tool available. This condition makes farmers market their cashew seeds directly. There is a problem that frequently encountered in marketing cashew seeds, namely the unconstant price of cashew seeds. This certainly affects farmers' income. Therefore, a study related to marketing channels for cashew nuts in the village of Gunung Silanu to see the price level at each marketing institution is needed. The purposes of this study were to determine marketing channels, analyze marketing margins, and marketing efficiency levels of cashew nuts (Anacardium occidentale) was a non-timber forest product at community forestry in Gunung Silanu Village. The results showed that there were two marketing channels. The first marketing channels were from farmers to large traders in the village of Gunung Silanu then to large traders in Jeneponto Regency. The second marketing channels were from farmers to small traders and large traders in Gunung Silanu Village then to large traders in Jeneponto Regency. The marketing margin of the big traders in the first channel is 15.6% with an efficiency level of 0.48%, while in the second channel is 13.4% and 11.3% for small traders and big traders respectively, so the total marketing margin is 23.3 % with an efficiency level of 0.48%. The most efficient channel is a channel with small costs, large margins, and a short marketing channel which is the first channel.

Jelutung is a tree species of the family Apocynaceae that is famous for its latex use as material for chewing gum. In Indonesia there are two species, namely jelutung land (Dyera costulata) and jelutung swamp (Dyera polyphylla). Until now, information on the differences in the two types of jelutung morphology is still very limited. There is therefore the need for a study on the variation of both types cultivated. This study was conducted to estimate variations in leaf morphology for land and swamp jelutung to assess 14 variables of its leaf morphology. Results of multivariate analysis (PCA, MCA, and CDA) showed that jelutung can be classified into two groups: D. costulata and D. polyphylla. PCA and MCA showed three variables that most distinguishes the two types of jelutung consecutive leaf length (PL), Roving Leaf (KL) and the shape of apex (AS). The CDA variables that play a major role in the classification of Dyera are the shape of apex (AS), the form of the base of the leaf (BS), leaf vein angle (SD).

Isu lingkungan yang terjadi disebabkan oleh salah satu faktor minimnya kesadaran dan pengetahun masyarakat terkait pengelolaan limbah rumah tangga. Dampak lingkungan yang tercemar dapat berpengaruh terhadap kondisi kesehatan, sosial dan ekonomi masyarakat. Pengelolaan limbah di kabupaten Halmahera Barat masih berupa pengelolaan open dumping. Pengelolaan limbah menggunakan sistem ini dapat mencemari lingkungan. Oleh karena itu perlu adanya upaya untuk mencegah dampak limbah terhadap lingkungan sebelum menyebabkan dampak yang lebih buruk. Salah satu upaya yang bisa dilakukan adalah membuat komposter dengan memanfaatkan pengurai berupa BSF (Black Soldier Fly) atau biasa dikenal dengan sebutan maggot. Perlu diadakan kegiatan pelatihan agar masyarakat mampu membuat komposter secara mandiri. Sehingga tujuan dari pelatihan ini yaitu tercipta masyarakat yang mandiri dan terampil dalam pemilahan limbah rumah tangga sesuai jenisnya dan dapat membuat komposter sederhana dari bahan limbah.

Khairun University Campus IV is currently being developed as an educational tourism location. One form of activity is developing agricultural land. The problem there is that the land is still not very fertile. Efforts that can be made are by developing ectomycorrhizal inoculants to increase soil fertility. Community service activities are directed at providing training to the community around Campus IV Unkhair in producing ectomycorrhizal inoculants. Ectomycorrhiza has several benefits for plants, namely being able to increase the uptake of P and N nutrients. The series of service activities carried out are providing training and practice in exploring ectomycorrhiza in the forest around the Unkhair campus IV area, training in the production of ectomycorrhizal inoculants, and training in applying ectomycorrhizal inoculants on agricultural land.

Sengon (Falcataria moluccana) is a legume that generally has physical dormancy. Physical dormancy causes slow seed germination if the dormancy is not broken properly. Many studies have been reported regarding dormancy breaking treatment with hot water on sengon seeds, but rarely use mechanical scarification treatment. The purpose of this study was to examine the effect of mechanical scarification on sengon seed germination. The experimental design used was a one-factor Completely Randomized Design (CRD). The factors used were the mechanical scarification technique (3 treatments), namely P1: control, P2: pricking the seed with a needle, and P3: cutting the tip of the seed. The germination parameters used were the percentage of germination (PK), peak value (PV), average daily germination (MDG), and germination value (NK). The results showed that the PK values for each treatment were P1 = 55%, P2 = 75%, and P3 = 72%. The PV values were P1=15.18, P2=17.75, and P3=17.53. The MDG values were P1=0.92, P2=1.25, and P3=1.20. The NK values were P1=13.90, P2=22.28, and P3=22.13. P2 treatment (needle prick) gave the highest response on all parameters of sengon germination. Based on the results of the Analysis of Variance (Anova), it was found that the treatment had a significant effect on the parameters PK, MDG, and NK. While the PV parameters showed no significant difference.
