Abstract

The objective of this study was to evaluate the use of bagasse-activated charcoal for reduced formaldehyde emissions and their effect on the physical, mechanical, and biological properties of particleboard. Activated charcoal was made by carbonizing bagasse at 300°C for 2.5 h, followed by carbon activation using a 0.1M HCl solution for 24 h. Particleboards were made of a mixture of bagasse and wood particles with a ratio of 100:0, 75:25, 50:50, 25:75, and 0:100. The concentrations of activated charcoal used in manufacturing particleboards were 2, 4, and 6% based on the dry weight of the particles. Particleboards were made with a target density of 0.7 g/cm3 and hot-pressed at 140°C for 10 min with a pressure of 35 kg/cm2. The observed parameters were formaldehyde emission levels, physical properties, mechanical properties, and biological properties of particleboards. The results showed that the more activated charcoal added in the manufacture of particleboards decreased formaldehyde emissions of the panel. Based on the SNI 5008.2:2016, the overall formaldehyde emission value of particleboard in this study with activated charcoal is in the F* category. The addition of activated charcoal improved the physical, mechanical, and biological properties of particleboards in terms of increased density, decreased water content, water absorption, and thickness swelling, increased modulus of elasticity, modulus of rupture, internal bonding, and screw withdrawal, as well as increased resistance to termites. The particleboard with the addition of 6% activated charcoal showed better mechanical, physical, and biological properties. All physical and mechanical properties of particleboard met the JIS A 5908-2003 Type 8 standards, except for the modulus of elasticity.

Abstract

Farmers choose an agroforestry pattern to fulfill various objectives, including obtaining their income. The diversity of fruit plants chosen by the Nanga Menterap village community as a component of the agroforestry system has the potential to contribute significantly as a source of community income. This research aimed to describe the agroforestry patterns and calculate the contribution of agroforestry patterns to the income of the people of Nanga Menterap Village, West Kalimantan Province, Indonesia. The research used a survey method by census. Data collection techniques included observation, questionnaires, and interviews with the Nanga Menterap Village community with agroforestry land. The agroforestry pattern in Nanga Menterap Village can be classified into two types: the agrisilvicultural and the agrosilvopastural. Farmers in Nanga Menterap Village apply a random mixture planting form in which crops and trees are planted irregularly. The agroforestry plants combined in the forestry component include durian (Durio zibethinus), aren (Arenga pinnata), tengkawang (Shorea stenoptera), mango (Mangifera indica), jackfruit (Artocarpus heterophyllus), and petai (Parkia speciosa). The agricultural component includes chili (Capsicum annuum), cocoa (Theobroma cacao), corn (Zea mays), coconut (Cocos nucifera), coffee (Coffea robusta), banana (Musa sp.), cassava (Manihot esculenta), long bean (Vigna unguiculata), ginger (Zingiber officinale), turmeric (Curcuma longa Linn. syn. Curcuma domestica Val.), eggplant (Solanum melongena), and tomatoes (Solanum lycopersicum), while the types of livestock such as pigs, domestic chickens, cows, and goats. The contribution of agroforestry to community income in Nanga Menterap Village is 82.74%. From these contributions, the agroforestry system is the right choice for the community and government to manage land. The governments should be able to facilitate and determine specific and targeted activity programs to improve the cultivation capabilities and welfare of farmers. Keywords: agroforestry, community, contribution, income
