Abstract

The aim of this research is to make an effort to utilize forestry waste, in the form of harvesting waste of acacia (Acacia mangiumWilld.) and coconut shells (Cocos nucifera L.) into particle boards by considering the evaluation of the value of particle board characteristics, both physical and mechanical characteristics in accordance with standards JIS A 5908-2003.This study used a factorial analysis where the first factor was the composition of the raw material for acacia: coconut (100: 0, 60:40, 50:50, 40:60 and 0:100). While the second factor is the provision of pretreatment on particles (cold soak, hot soak and without immersion).This analysis was carried out in a completely randomized design (CRD) with three repetitions.The results showed that the composition of the raw materials had a significant effect on the value of water content, water absorption, modulus of rupture and modulus of elasticity.The pretreatment had a significant effect on the thickness swelling, water absorption, modulus of rupture and modulus of elasticity. Meanwhile, the interaction of these two factors has a significant effect on the internal bond value, modulus of rupture and modulus of elasticity.Based on the results, it is known that only the density parameters that meet the JIS A 5908-2003 standard, the moisture content and thickness development parameters have not met the standards, while the mechanical characteristics of the particle board have not met the standards.Overall particle board with the composition of acacia raw material: young coconut 60:40 and heat soaking pre-treatment can produce good quality particle board.

Abstract

KTH Aren Serbaguna has collaborated with the community service team in 2020 regarding training on making palm sugar, the results of the community service partners were very enthusiastic about participating in the training activities because some of the livelihoods of the residents in this village are palm sap farmers. The results of discussions with residents (farmer groups) wanted a supply of palm plants planted from superior palm seeds so that their livelihoods could continue and hopefully the production of printed palm sugar would grow. Therefore, steps need to be taken for its cultivation efforts for the sustainability of palm sugar production in the village. The solutions offered by the community service team for the partner's problems above, include: conducting counseling on understanding the characteristics of palm (Arenga pinnata), growing requirements, potential and distribution, especially how to cultivate palm by making palm nurseries, conducting training and mentoring on palm seedling techniques from parent trees and planting superior palm seeds at partner locations.

Abstract

ABSTRACT Sengon wood (A. chinensis) is a type of wood that has great potential as a source of industrial raw materials and holds significant economic value. However, sengon wood has low natural durability, classified as durability class IV–V, making it highly susceptible to attack by wood-destroying organisms such as termites. Therefore, wood preservation treatment is necessary to extend its service life. This study aims to analyze the interaction effect between the concentration of gadung tuber (D. hispida) extract with ethanol solvent and the soaking duration on the durability of sengon wood using the cold soaking method. The extract concentrations used were 1%, 3%, and 5%, and the soaking durations were 1 day, 2 days, and 3 days. The preserved samples were subjected to forced feeding tests using 50 healthy and active drywood termites (C. cynocephalus Light) on test specimens measuring 2.5 cm × 2.5 cm × 2 cm. The preservative performance parameters included absorption and retention, while the wood durability parameters included weight loss and termite mortality rate. The interaction between gadung tuber extract concentration and soaking duration significantly affected the retention and absorption values, while weight loss and termite mortality showed no significant effect. The highest retention and absorption values were obtained at a soaking duration of 3 days and a concentration of 5%, with average retention and absorption values of 0.028 g/cm³ and 0.438 g/cm³, respectively   Keywords: drywood termites, gadung tuber extract, sengon wood, wood preservation   ABSTRAK Kayu sengon (A.chinensis) merupakan kayu yang memiliki potensi sebagai penyedia bahan baku industri dan memiliki nilai ekonomi yang cukup besar. Kayu sengon memiliki tingkat keawetan yang rendah, yaitu kelas awet IV-V sehingga sangat mudah diserang oleh organisme perusak kayu seperti rayap. Perlu dilakukan proses pengawetan kayu untuk meningkatkan umur pakai kayu. Penelitian ini bertujuan untuk menganalisis pengaruh interaksi antara konsentrasi ekstrak umbi gadung (D. hipsida) dengan pelarut etanol dan lama perendaman terhadap keawetan kayu sengon dengan metode perendaman dingin. Konsentrasi ekstrak yang digunakan 1%, 3% dan 5% dan lama perendaman yang dilakukan 1 hari, 2 hari dan 3 hari. Pengawetan diumpan paksa dengan rayap kayu kering (C. cynocephalus Light) yang sehat dan aktif sebanyak 50 ekor pada contoh uji yang berukuran (2,5 cm x 2,5 cm x 2 cm). Parameter pengujian bahan pengawet terdiri dari absorbsi dan retensi, sedangkan parameter pengujian keawetan kayu terdiri dari penurunan bobot dan nilai mortalitas rayap kayu kering. Interaksi antara konsentrasi ekstrak umbi gadung dan lama perendaman terhadap keawetan kayu sengon memberikan pengaruh nyata terhadap nilai retensi dan absorbsi, sedangkan penurunan bobot dan mortalitas tidak memberikan pengaruh nyata. Interaksi retensi dan absorbsi nilai tertinggi diperoleh pada lama perendaman 3 hari dan konsentrasi 5%, dengan nilai rata-rata retensi 0,028 g/cm3 dan absorbsi 0,438 g/cm³.   Katakunci: ekstrak umbi gadung, kayu sengon, pengawetan kayu, rayap kayu kering

Abstract

The existence of expanding oil palm plantations is inevitable, as it has contributed significantly to increasing household incomes. However, the continued practice of monoculture oil palm plantations in forest areas poses a critical challenge to the sustainability of the ecosystem. This study aims to analyze farmers’ perceptions and participation in oil palm-based agroforestry management, as well as the relationship. Data collection was conducted through interviews, data were analyzed using a descriptive qualitative approach and a quantitative approach using Chi Square. The variables studied were farmer perception (X) and farmer participation (Y).The study population consisted of members of Forest Farmer Groups (KTH) in the Jangka Benah program a collaborative effort between the Forest Management Unit (KPHP) Unit XVI Tanjung Jabung Barat and the Natural Resources Conservation Agency (BKSDA) of Jambi Province. This program was implemented in Sungai Penoban Village and involved three farmer groups: KTH Anugerah, KTH Bukit Indah, and KTH Tri Jaya Makmur. The results of the study indicate that although farmers generally have positive perceptions, but the farmer participation is very low. The results of the Chi-Square test indicate that there is no significant relationship between perception and participation in Jangka Benah programs (0.406) with a contingency degree of 0.1 (very weak). The main factor influencing this reluctance was concern over potential economic risks, especially the perceived threat of reduced oil palm productivity. In addition, poor growth of intercrops planted three years earlier further hampered participation, ultimately leading most farmers to discontinue agroforestry practices in their oil palm plantations.
