Abstract

Nowadays binderless particleboards have chance to be developed to replace particleboard with synthetic adhesive. Theobjectve of this research is to determine the quality of particleboards made from oil palm empty fruit bunches (OPEFB)and pine bark waste. The material composition of particleboard consist of 70% OPEFB and 30% pine bark powderwith a moisture content of 5−6%. The fiber length of OPEFB is 0.1−2.0 cm and the pine bark particle sizes usedto produce particleboard which passed through 30, 40, and 50 meshes. Four variations of pressing time are applied toproduce particleboard i.e 10, 15, 20 and 25 minutes. Quality assesments were undergone using the Indonesian standardfor particleboard product: SNI 03-2105-2006. Results showed that the best pressing time for making particleboardsusing OPEFB and pine bark is 20−25 minutes. The best MOR and IB are obtained from particleboard producedfrom oil palm fruit empty bunches with the particle size of 50 mesh. In this condition, except for MOE, the density,moisture content, MOR and IB meet the SNI requirements for particleboard.

Abstract

Characteristics of Apis dorsata`s forest honey from bioregions of Riau have not been studied intensively. Thisresearch is aiming to provide characteristic information on honey from bioregions of Riau based on SNI 8664-2018.The study was conducted in September to November 2015. Honey samples were collected from eight districts of sixbioregions in Riau Province, i.e Bengkalis and Selat Panjang (downstream), Kampar (mineral forest), Pelalawan(peat swamp forest), Rokan Hilir (river bank), Siak (Acacia plantation forest), and Kuansing (oil palm and rubberplantation). Samples of each bioregion were analyzed based on SNI 8664-2018 procedures. Results show that wildhoney characteristics were not significantly different among bioregions for almost all parameters in SNI 8664-2018.However, the diastase enzyme parameter in honey taken from Pelalawan was the only parameter that had significantvalue. In addition, the parameter of water content and reducing sugar content were only two parameters that did notmeet the SNI 8664-2018 requirements. Meanwhile, the type and size of pollen could be used for determining the originof honey between Riau bioregions.

Abstract

Porang (Amorphophallus muelleri Blume) as a non-timber forest product (NTFP) has many advantagescompared to other food crops. In order to the cultivation aspect and excellence of the flour, it made this commodity afood sources in the future. Today, technical post-harvest processing become the current problems especially in gettingoptimum glucomannan. With increasing levels of glucomannan, it made the utilization and marketing of flour will bewider. This study aims to optimize of purification techniques of glucomannan. The research method is through soakingtechniques with ethanol (30%, 40% and 50%) and sodium bisulfite (2%, 3% and 4%). The results showed that theleaching technique ethanol made a significant effect on the increase in glucomannan levels. The immersion technique with50% ethanol and 2% sodium bisulfite can increase glucomannan from 32.65% to 83.96%. The process of soakingwith ethanol not affects the content of ferrum (Fe) and calcium (Ca) in porang flour.

Abstract

Heat treatment is one method that can improve the quality of wood including for fast-growing wood species. However,this treatment can cause some drying defects as well as the change of machining properties after applying that heattreatment. The purpose of this study was to evaluate the effect of wood species and heating time on the drying andmachining defects. The fast-growing wood species used were teak, mangium, jabon, and sengon. The heat treatmentwas carried out at a temperature of 165°C with variation in time were 0 (control), 2, and 6 hours. The result showedthat the moisture content and wood density decreased after heat treatment. Heat treatment was succeeded to decrease themoisture content of 57% and caused a decreasing of density until 20% compared with control wood. The drying defectsof end checks in teak, mangium, jabon and sengon increased after 2 and 6-hour heat treatment. In the other hand, thesurface checks defect of teak, mangium, sengon and jabon were decreased. The defects after applying machining activitiesi.e. the defects of sanding, planing, shaping, and boring were decreased in teak, mangium, jabon and sengon after heattreatment of 2 and 6-hour. Jati was the best wood species in term of machining quality followed by jabon, mangium,and sengon after heat treatment. At the temperature of 165°C in 2 hours could be considered as the appropriate timefor heat treatment in term of obtaining minimal defects of drying and machining.

Abstract

Left over wood felling waste is an alternative sourcse for energy from forest biomass. This research is aiming tostudy the quality of briquettes made of left over galam wood felling as alternative energy raw material. Left overgalam wastes is in the form of stems, twigs, leaves, and bark of galam. The waste was burned into charcoal and grindthem into charcoal powder and formed into briquettes using a hydraulic press. The briquetting process wasconductedusing two variations in pressure and the percentage amount of adhesive mixed. The charcoal briquettes produced werethen analyzed for quality and it was compared to the Indonesian standards (SNI 01-6235-2000) and other qualitystandards for commercial briquettes. Results showed the calorific value at briquettes from stem, twigs, leaves and galambark between 5139.01–6948.50 cal/g, moisture content 3.91–24.45%, ash content 3.08–12.49%, and volatilematter 23.91–37.54%. In general the quality of galam wood briquettes shows a high heating value, so that it could beused as a new biomass-based alternative energy.
