South Kalimantan has considerable natural forests and many types of timber that have not yet been optimally utilized, such as Bangkal tree (Nauclea officinalis). The purpose of this research was to analyze chemical components, dimensional fibers characteristic, and suitability of Bangkal wood as a raw material of pulp and paper. The results obtained from this study revealed that the chemical content of Bangkal wood consisted of 3.00% extractive, 30.00% lignin, 16% hemicellulose, and 50.50% cellulose. The anatomy of Bangkal wood were 1.40 mm in fiber length 1.40 mm, 1.20 μm in fiber diameter, 5.00 μm in lumen diameter, and 3.25 μm in cell wall thickness. Derived fiber values comprised Runkel Ratio (0.43), Power Weaving (66.00), Muhsteph Ratio (99.80%), Coefficient of Rigidity (0.20), and Flexibility Ratio (0.71). Based on the chemical components and quality of Bangkal wood fiber, that wood could be used as a raw material of pulp and paper.

The Trigona sp. bees do not require specific breeding treatment. Nevertheless, selection of shade, container or media to cultivate this stingless bee can be engineered to increase the production of honey. This study was aimed to determine the effect of diameter, length, and thickness of bamboo used as a beehive of Trigona sp. The beehive was prepared from 54 thorny bamboo’s culms with various sizes. Hole was made on the culms where the queen and propolis could be inserted into the culms. Those inserted culms were then put in the cultivation place. The honey resulted from each culm was calculated after 4 months of the cultivation. The results showed that total honey production, HPB (honey, propolis, bee bread), and bee bread were 221.3 g, 792.7 g, and 33.8 g. Regression analysis revealed that there wa a significant effect of bamboo’s diameter on honey production, but not on bee bread, egg’s weight and HPB. Recommended diameter of bamboo culms for the cultivation of Trigona sp. was about 6-12 cm to obtain better quantity of honey

The second generation of bioethanol derived from various cellulosic biomass materials is one of the latest renewable energy as the alternative of fossil fuel. The cellulosic waste based wood and non-wood materials are the most abundant natural resource on the earth, renewable, and inexpensive. Currently, second generation bioethanol development is still not optimally done due to various obstacles, especially the pretreatment process to eliminate lignin, influencing the conversion process of cellulose into reducing sugar. Hydrothermal method is one of lignocellulose pretreatments, which is widely developed because this method is relatively cheap and environmentally friendly with the utilization of water-based solvent. Hydrothermal methods performed at high temperature and pressure in a relatively short time are able to deconstruct the lignocellulose structure that enables cellulase enzymes to access cellulose for hydrolysis. This study discussed about the development of hydrothermal method for lignocellulose pretreatment process to increase production of second-generation bioethanol. Some aspects studied in this research were structural change, chemical composition, lignocellulosic crystallinity before and after hydrothermal processes, and hydrothermal effect on the production of reducing sugars. Hydrothermal method could be used and developed as an efficient and cheap method as the first treatment of lignocellulose waste in attempt to increase the production of bioethanol.

Current issues of energy sector in Indonesia can be summarized as depletion of fossil energy reserves which is dominated by fuel oil and coal. Oil production continues to decline and the increase in oil fuels demand lead to increase imports of crude oil and oil fuels. To use lignocellulosic biomass waste has become a major alternative to replace fossil fuels and chemical feedstocks production. In 2015, total rice production in South Kalimantan reached 2,140,276 ton and rice straws were abundant waste which could be utilized as raw material for bioethanol production. Pretreatment process of lignocellulose is a crucial step to remove lignin because of the complex chemical cross-linking between chemical components. Delignification of lignin can increase the accessibility and digestibility of enzymatic, and help to promote enzymatic hydrolysis. Nowadays, pretreatment process with green chemistry method is continuesly developed by researcher to reduce the production costs and thus avoid adverse effects on human and the environment. This article disscussed about green methods for pretreatment of lignocellulosic material using deep eutectic solvent (DES) to increase second-generation bioethanol production in South Kalimantan.

Kalakai (Stenochlaena palustris) is a fern that lives wildly in nature. High iron content in the diet underlies the use of kalakai plants as a natural iron fortifying food for growing children. The purpose of this study was to determine the best formulation of baby porridge flour meeting the Indonesian National Standard (SNI). Kalakai was selected as a Fe fortifying material due to its high content of Fe. Three formulations (A, B, and C) were produced from three different flours (cassava nagara, kalakai, and young banana), and the formulated samples were tested. Formula A was 55 (cassava) : 5 (kalakai) : 40 (banana); formula B was 57:3:40; and formula C was 59:1:40. Those three formulations were compared with a control which was made from cassava nagara flour and banana flour with ratio of 60% and 40% (without kalakai). The results showed that the best formula was the A formulation, with a ratio content of 55:5:40. This formula had 0.90 g/ml of kamba density, 2.04 of water absorption index, 6.62% of moisture content, 3.02% of ash content, 0.67% of fat content, 2.41% of crude protein, and 4.48 mg/100g of Fe level.

Biodegradable foam is a packaging material intended as a substitute for styrofoam. Materials used in this study were mahuli banana (Musa acuminata) stem and nagara tubers (Ipomoea batatas L) with aim to find out the best composition material for the best physical characteristics of biodegradable foam. Prior to use in the process of making biodegradable foam, mahuli banana stem and nagara tuber were firstly pulverized to a size of 100 mesh. Then, the mahuli banana stem and nagara tubers powders were mixed with compositions of 60:40, 70:30, and 80:20; and as controls pure material was utilized. Another treatment was the addition of PVA (polyvinyl alcohol) as much as 10%v/v and no addition of PVA (UNPVA). The process of making biodegradable foam began with plasticizing on a hotplate at 150oC for 3 minutes, thermopressing, and drying in a microwave. The biodegradable foam (bio-foam) characteristics were tested with DSC and SEM as well as for its hardness and biodegradation. Based on the results of hardness test, DSC, SEM and biodegradation, the best physical characteristic was obtained from 60:40 composition with the addition of PVA. The hardness test of bio-foam with PVA and UNPVA was 4.02 MPa and 3.59 MPa, respectively. The melting point of bio-foam with the addition of PVA was 166.50 oC with heating flow of -12.38 MW whereas the melting point of bio-foam without UNPVA addition was 166.45 oC with heating flow of -16.07 MW. The result of SEM test showed that bio-foam mixed with PVA had a smaller pore compared to UNPVA. The structure of bio-foam with a smaller pore produced biodegradable foam with higher compressive strength. Biodegradation test results showed that both samples were completely degraded after ± 2 months of being deposited in the soil.

The purposes of this research were to study the ieffects of biomass moisture content and process temperature on the quality of biopellet derived from rubber seed shell and bamboo ater (Gigantochloa atter). The biomass was conditioned at different moisture contents (6, 12, 14, 16, 18, and 20% w/w), and the biopelet was produced at a pressure of 597,24 kg/cm2 with various process temperatures (100, 125, 150, 175, and 200oC). The results showed that the properties of produced biopellets were significantly affected by the variation of moisture content and process temperature. High moisture content of biomass could increase the moisture content of biopellet while the calorific value and ash content decreased. With the increase in process temperatures, calorific value and ash increased whereas the moisture content of biopellet decreased. Mechanical durability was enhanced with the increase inthe moisture content of biomass, starting from 6% to 18%;and was improved with the increase in the process temperatures, starting from 100oC to 175oC. However, the bulk density of biopellet increased with the increase inthe moisture content of biomass, starting from 6% to 16%, and was improved with the increase in the process temperatures from 100oC to 150oC. The best quality of biopellet was produced in the biomass moisture content of 16% and the process temperature of 150oC. That biopellet had mechanical durability of 99.16%, calorific value of 4,402 cal/g, bulk density of 1,157 kg/m3, moisture content of 6.71%, ash of 1.19%, nitrogen of 0.15%, Sulphur of 0.013%, and chlorine of <0.1 ppm. That biopellet quality met European standards (EN 14961-2).

The purpose of this research was to analyze the physical and chemical properties of sago starch edible film (Metroxylon sagu Rottb) as capsule shells material. The research was started with the extraction of the rumbia starch, and was followed with the production of edible film added with modified carrageenan concentrations (20% and 30% w/w) to the main compound. Organoleptic test showed that the color and odor of the films were normal. Water content of wet sago and dry sago was 12.55%, and 5.38%, respectively. Although the addition of carrageenan increased the water content but still corresponded with SNI gelatin quality standard with a maximum of water content of 16%. The ash content of fresh sago and dry sago was 0.36% and 1.09%, respectively, and the content increased significantly with the addition of carrageenan. The pH of all varied samples was 5.5 – 7.0, and the pH was in accordance with SNI. Meanwhile, the heavy metal content of the samples measured by means of AAS was negative. Based on viscosity testing withBrookfield method, high carrageenan concentration led to low viscosit. tensile strength test based on ASTM D 882-2002 gave positive results for dry sago (21.05 kg/cm2) whereas fresh sago with modified 20% and 30% carrageenan had tensile strength of 5.33 kg/cm2 and 18.18 kg/cm2, respectively. The results showed that sago starch had the potential as a raw material for producing soft capsules by modified composition to enhance physical and mechanical properties in order to meet the quality standard of edible film.
研究了西米淀粉可食性薄膜作为胶囊壳材料的理化性质。本研究从提取蚕豆淀粉开始,在主要原料的基础上分别添加20%和30% w/w的改性角叉菜胶,制成食用膜。感官检查显示膜的颜色和气味正常。湿西米含水率为12.55%,干西米含水率为5.38%。虽然卡拉胶的加入增加了水含量,但仍符合SNI明胶的质量标准,最大水含量为16%。鲜西米和干西米的灰分含量分别为0.36%和1.09%,随着卡拉胶的添加,其含量显著增加。不同样品的pH值在5.5 - 7.0之间,pH值与SNI一致。同时,原子吸收光谱法测定样品的重金属含量为负。根据布鲁克菲尔德法粘度测试,高卡拉胶浓度导致低粘度。根据ASTM D 882-2002的抗拉强度测试,干燥西米的抗拉强度为21.05千克/平方厘米,而添加20%和30%卡拉胶的新鲜西米的抗拉强度分别为5.33千克/平方厘米和18.18千克/平方厘米。结果表明,通过对西米淀粉进行改性,可以提高西米淀粉的物理力学性能,从而达到食用薄膜的质量标准。

An added value of bamboo charcoal that is commonly used as an energy source could be increased by the addition of activator and metal doping. The objective of this research was to analyze the effect of the addition of activator and doping to the electrical conductivity and carbon characteristics for a raw material of bio-battery. Bamboo plantsused in this experiment were buluh, haur, and betung. Bamboo was carbonized inthe temperature range between 500oC and 600oC by pyrolysis method. Obtained charcoal was activated using two types of chemicals, KOH and HNO3, and then was doped with Zn and Ni. Furthermore, obtained carbon was made into nanoparticles using High Energy Milling. The structure and properties of the carbon were tested using PSA, SEM, and XRD; and the conductivity was also tested. The smallest particle size was obtained from ‘buluh’ bamboo charcoal with HNO3 activation and without a doping at 1030 nm. The diffractogram and topography of the bamboo charcoal varied depending on the metal doping added. The highest electrical conductivity (DHL) was obtained from betung charcoal with an activator of KOH and a doping of Zn at 7.02 mS/cm.
