The difference between agroforestry and monoculture planting system is the presence of organic materials input from the canopy tree or the roots. The study aimed to determine factors affecting micro-climate conditions, soil nutrients of C, N and to identify the influence of sengon plantation on snake fruits productivity. This research used the observation method and was conducted in Gadung village, Bangunkerto, Turi. The treatments were the location used pattern monoculture system (control), agroforestry with trees along borders (AFS), and full trees (AFT). The soil was sampled compositely one diagonal. Analyses descriptive and regressions were used to analyze data of the soil nutrient with the treatment and fruit productivity. The results showed that the presence of Sengon on salak plantation influenced micro-climates conditions due to canopy cover by sengon. A location AFT showed the highest value of C-org (1.7%), and N (0.1%) in all plots. Meanwhile, the productivity of fruits on the monoculture system showed the highest fruit production that was 1150 kg/ha. However, the results were not significantly different from AFS and AFT. The snake fruit productions of AFT and AFS were 1035 and 1085 kg/ha, respectively. The results suggested that sengon plantations increased soil fertility, i.e., C and N...

Kapok wood (Ceiba pentandra (L.) Gaertn) is a low-density wood species that can become a light construction material in the form of laminated timber products. This study aimed to understand the properties of laminated timber from kapok wood at different sawing patterns of laminae and core layer orientation. This study used kapok wood produced from community forests and PVAc (Polyvinyl Acetate) resin as the binder to produce laminated timber. The laminated boards were manufactured from dried laminas, measuring 100 x 9.5 x 1.7 cm, and were glued together with the resin before being pressed and clamped with the pressure of 1 MPa for 12 hours. The dimension of the final laminated board was 100 x 38 x 5 cm. Before being cut for the physical and mechanical properties tests, the laminated boards were conditioned at room temperature for a week. The results indicated that sawing patterns had insignificant effects on moisture content, density, static bending properties, and bonding strength of laminated boards. The core layer orientation had a significant effect on the density and the modulus of rupture. Generally, laminated board from kapok wood with the parallel grain direction of the core layer resulted in higher static bending properties and...

In the cultivation of teak plus Perhutani (JPP) plantations, there is a thinning cycle of plants at a certain age to produce optimal plant growth for other teak trees. The wood waste from thinning in the form of tree tips and branches/twigs is commonly only used as firewood. One of the efforts to diversify the use of thinned JPP wood is processing it into wood pellets. The raw material used is ten years old thinning teak from Perhutani KPH Pemalang, Central Java. The purpose of this study was to identify the effects of adding tapioca flour on the quality of wood pellets from teak branch waste. In this study, the manufacture of pellets was carried out with treatments without the addition of tapioca and the addition of 2.5%, 5%, 7.5%, and 10% w/w of tapioca adhesive. The results showed that the waste of teak branch can be used as raw material for wood pellets, with the characteristics of the water content 6.51-6.97%, volatile matter 76.01-77.37%, ash content 1.37-1.67%, fixed carbon 14.74-15.49%, density 1.14-1.31 g/cm3 and heat value 4192-4319.67 cal/g. The results showed that all parameters met SNI 8021-2014, except for the ash content in the control and 2.5% tapioca treatment.

This study aimed to analyze several secondary metabolite compounds that are antioxidants in the leaves of gaharu plants based on the position of the leaves on the branches. The experimental design used was a non-factorial randomized block design. The research treatment consisted of three factors, namely (A1) young leaves (position of 1-4 leaves from the shoot), (A2) medium leaves (position of 5-8 leaves from the shoot), and (A3) old leaves (position of 9-12 leaves from the shoots). The results showed that the position of the leaves on the branch of the gaharu plant significantly affected the number of secondary metabolites produced. Gaharu plant leaves contain secondary metabolites, namely alkaloids 1.65-4.20%, saponins 2.47-4.00%, tannins 0.69-2.70%, total phenol 29.70-54.68 mg/L, and total chlorophyll 9.21-20.03 mg/L. Tannins and total phenols are functional compounds in gaharu leaves which are antioxidants. The antioxidant properties of this leaf are included in the strong category with an IC50 value of 49.30-68.30 mg/L wherein young leaves have higher antioxidant properties than old leaves.

The calorific value is a parameter of palm biomass to determine its energy value. Extractives of wood is one of the factors that affect the calorific value. This study aimed to prove the positive effect of extractives on increasing calorific value by identifying the effect of adding extractives on low calorific value biomass. The study used three species wood energy, i.e., Calliandra calothyrsus, Gliricidia sepium, and Leucaena leucocephala. The soxhlet extraction was carried out to isolate extractives from sample. The calorific value sample and residue after extraction were analyzed to evaluate the changes of calorific value due to loss of extractives. The effect of extractives on the calorific value was confirmed by adding wood extractives to the palm biomass. The results showed that the extraction process reduced calorific value of residue ranging from 2.63 to 5.88%, and the bark it ranged from 5.52 to 6.70%. The addition of wood extractives to palm biomass increased the calorific value about 5.86-10.33%, while the addition of extractives from bark increase the calorific value by 6.45-9.05%. Based on the results of these studies prove that extractives have a positive effect on increasing the calorific value and can be used as an additive to increase...

The multi-function forests establishment is an appropriate solution for the paradigm transition in forest management from timber management into ecosystem management. Inclusive economic and environmentally friendly business models become a necessity in forest management to ensure the sustainable functions of forests as life support systems. The multi-business in forestry regulated by Ministerial Decree -PerMen-LHK No.8/ 2021- is in line with the spirit of multi-function forests paradigm to increase forest lands productivity, not only timber but also non-timber forest products and environmental services. Although the government has formulated the multi-function forests development concept and its strategic plan several years ago, the forestry sector's contribution in economic valuation, such as national income (PDB—gross domestic product) and non-tax revenue (PNBP—non-tax state revenue) is relatively low. In this disruption era, this forest management transition becomes a necessity. The multi-function forests establishment could become a realistic management model to implement business diversification and innovation and optimize forestry competitiveness at each business level to accommodate social, economic, and environmental aspects of forest management.
