Abstract

Smoke liquid is a liquid obtained from smoke condensation during charcoal firing process. The main content of the smoke liquid is acetic acid, hence, can be used as an alternative latex coagulant. Acid in vinegar can reduce the pH of latex and cause the latex to coagulate rapidly. This paper determines effectiveness of using smoke liquid as a latex coagulant and characteristics of the treated latex. The smoke liquid in this study was derived from pine wood. The smoke liquid solutions consisted of the crude smoke liquid and the diluted solution in various concentrations of 5, 10, 15 and 20%. The smoke liquid solution was then each poured into a container of latex. Testing was undergone by observing latex coagulating time, coagulate condition, texture, color, odor and homogenity. The most effective smoke liquid which produced the best latex based on its performances was then taken for further testing of physico-chemical properties which included dry rubber content, plasticity retention index (PRI), initial plasticity (Po), final plasticity (Pa), dirt content, ash content, volatile matter content (Vm), and nitrogen content. Results were then compared with the conventional use of formic acid as a control coagulant. The result showed that the crude and distillate smoke liquid solutions with concentration of 10% produced the best coagulantperformances than the other solutions. Rubber latex treated with the crude smoke liquid produced the best physico-chemical properties and could meet requirements of the Indonesian National Standard (SNI) for Rubber Quality.

Abstract

Biodiesel is a diesel fuel made from vegetable oils extracted from various forest plants. This paper studies the characteristics of biodiesel made from Bintaro's seed (Cerbera manghas L.) by modified process. The modification process includes pretreatment and degumming processes. In the pretreatment process, modification includes raw material's treatment such as steaming, washing, drying and compressing. Degumming modification process includes addition of phosphoric acid catalyst, then bentonite; esterification by methanol acid catalyst and followed by addition of zeolite; the transesterification process by methanol bases catalyst. Results show that physico-chemical properties of biodiesel made from Bintaro's seeds including acid value, density, iod number, viscosity and ester-alkyl content met to Indonesian National Standard (SNI) on Biodiesel.

Abstract

Petroleum consumption is increasing, while the supply is continuously depleted. Currently, the alternative biofuel such as bioethanol, biodiesel and bio-oil have been developing from various natural sources, including forest product’s waste. This paper studies the characteristic of bio-oil made of wastes from forest industries by fast pyrolysis process. Mahogany wood powder, bark and paper sludge were heated in the temperatures of 400°C, 450°C, 500°C, and 550°C to produce bio-oil. Results show that bio-oil can be produced from all three materials studied. Mahogany wood powder which was heated at 550°C produces the highest liquid yield of 25%, yields of bio-oil is 5%, phenol 3.66%, pH 2.98, specific gravity 1.092 g/cm³, heating value 9.28 MJ/kg. The fast pyrolysis process produces bio-oil which is predominantly composed of acetic acid and phenols.

Abstract

Biomass resource mainly from forest industries waste such as oil palm empty fruit bunches (TKKS) is abundantly available, Currently, the utilization of TKKS as pyrolysis products is still limited to charcoal product, activated charcoal and charcoal briquettes. On the other hand, research on bio-oil manufacturing from biomass using fast pyrolysis method may increase hydrocarbons and calorific values, however the amount of catalyst used is higher than the biomass. This paper observes data and information on the characteristics of bio-oil made from oil palm empty fruit bunches through the addition of Ni/NZA as a catalyst. The optimal results (yield 30.27%, pH 2.94, specific gravity 1.068, viscosity 44 cSt and calorific value 29.38 MJ/kg with flame in medium category) were obtained with the addition of 6% catalyst. The bio-oil produced was dominated by acetic acid, phenol and benzene or toluene, and there were also alkene hydrocarbons compound, for instance hexadecene and aromatic hydrocarbons naphthalene.

Abstract

Carbon pellet is a charcoal product made from carbonized biomass which is crushed into fine powder and compacted into pellet. Carbon pellets is designed for renewable energy alternatives for cooking, the combustion process and the possibilities for steam power plants as a substitute for coal. This paper studies the quality of carbon pellet made from a mixture of elephant grass with nyamplung shell. After carbonization, the elephant grass and nyamplung seed shell were crushed into 60 mesh powder for pellet with various ratio of elephant grass charcoal and nyamplung shell charcoal namely 100:0, 75:25, 50:50, 25:75, and 0:100 homogenously. Ten percent PVAC adhesive was added into the mixture prior to compression. Results show that the mixture composition of 75% elephant grass charcoal and 25% nyamplung shell charcoal is recommended for carbon pellet. The mixture composition improved physical properties with the average of 3.35% water 3 content, 26.19% volatile matter, 13.59% ash content, 60.21% carbon bound, 0.68 kg/cm density, 5.91 kg/cm compressive strength and calorific value of 6080 cal/g.
