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.","PeriodicalId":53028,"journal":{"name":"Jurnal Riset Industri Hasil Hutan","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76956145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":53028,"journal":{"name":"Jurnal Riset Industri Hasil Hutan","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83682202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":53028,"journal":{"name":"Jurnal Riset Industri Hasil Hutan","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89889003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.
