Abstract

In Indonesia, 187 million tons of biomass were produced from 8.11 million ha of oil palm plantation in 2009. This massive amount of biomass mainly consists of oil palm fronds (OPF) and oil palm empty fruit bunches (EFB), which are normally categorized as waste. The properties of OPF fibers compared to those of synthetic fibers, such as low density, low cost, less abrasion of equipment, and safer production, makes them an attractive reinforcement for composite materials. In this work, the utilization of oil palm empty fruit bunch ash for OPF fiber-polyester resin composite and the effect of process conditions were studied. Water absorption, tensile and flexural strength were used to characterize the effects of alkaline treatment on modified OPF fibers in polyester resin. The investigation focused on the effect of alkaline treatment time. Treatment temperature and liquid to solid ratio were analyzed using Response Surface Method-Central Composite Design (RSM-CCD). The highest tensile strength (44.87 MPa) was achieved at 12 hours soaking time, at 40°C treatment temperature and 5:1 water to ash ratio. The highest flexural strength (120.50 MPa) was obtained at 1.3 hours soaking time, 4 dissolving ratio and 35°C treatment temperature. The lowest water absorption of composite (3.00%) was achieved at the longest soaking time (14.7 hours), 4 dissolving ratio and 35°C treatment temperature. Variance of soaking time, dissolving ratio and temperature in the alkaline treatment process using extract of oil palm empty fruit bunch ash significantly affected the mechanical and physical properties of the oil palm frond fibers reinforced composite.

Abstract

The sodium lignosulfonate (SLS) is a derivative compound from lignin which has various usefulness. Commercial SLS is a by-product of Arbiso pulping sulfite industry, but nowadays, the amount of available commercial SLS is scare due to the expensive price of SLS. Therefore, it is needed to find the solution to produce of SLS using a feasible process. This research involves producing SLS by directly cooking the palm oil stem biomass dust in a pressurized reactor using sodium bi-sulfite (NaHSO3) solvent. The experiment focused on the modeling, influence of process variables and its optimization that statistically analyze using the Response Surface Method-Central Composite Design (RSM-CCD). The result showed that the solid-liquid ratio is the most affecting factor to the SLS rendemen. The relation between rendemen and temperature (T), pH (C) and solid-liquid ratio (R) can be modeled as % rendemen = 12.18 + 0.52T – 0.48C + 3.5R – 1.02T2 – C2 – 1.53R2. The optimal operation conditions were identified at temperature of 153.8oC, pH = 4.64 and solid-liquid ratio of 1:15.9.

Abstract

Energy auditing is one of the steps made in an effort to realize energy saving programs. The energy widely used in the pulp and paper industries is thermal energy (steam) and electrical energy. Pulp drying is one of the processes that many use such energy. The thermal energy used was of low to medium pressurized steam, which used to increase air temperature to dry pulp sheet. Research were conducted to identified energy usage and potency of energy saving in pulp machine especially in Pulp machine 1 and 2 area. The results of the study were found the influence of downtime to production cost. 30 minutes down time will increase production cost to $0.3545/ton pulp. Used of acacia as raw material will make pulp machine possible to run 1 screening system. It give benefit $ 2180.8 per day. Besides, the study also found four “steam trap” units and six “valve” units with “Passing" (leaking)” conditions that made “losses steam” of 467.8 Kg/hr or 1,467 tons of steam/year or about IDR 240.051,840 in a year. The inverse improvements/recovery of “steam trap” positions can save steam with a saving percentage of 0,34% of total steam costs per year and will return investment capital for four hours. Whereas the turnover on leaked “steam trap” units could save steam of 2,574 tons of steam/year with a savings percentage of 0.60% of total steam cost per year and would return investment capital for four months.Keyword: Electricity, Energy Audit, Pulp Dryer, Steam

Abstract

Energy auditing is one of the steps made in an effort to realize energy saving programs. The energy widely used in the pulp and paper industries is thermal energy (steam). Pulp drying is one of the processes that many use such energy. The thermal energy used was of low to moderate pressurized steam, which was supplied into a number of rotating dryer cylinders. Evaporation is done because water can no longer be removed from the fiber by gravity and vacuum in the forming of the unit and mechanically in the pressing of the unit. The results of the study were found two “steam trap” units with “inverted” installation positions and four “steam trap” units as well as six “valve” units with “Passing" (leaking)” conditions that made “losses steam” of 467.8 Kg/hr or 1,467 tons of steam/year or about IDR 240.051,840 in a year. The inverse improvements/recovery of “steam trap” positions can save steam with a saving percentage of 0,34% of total steam costs per year and will return investment capital for four hours. Whereas the turnover on leaked “steam trap” units could save steam of 2,574 tons of steam/year with a savings percentage of 0.60% of total steam cost per year and would return investment capital for four months.Keywords : Pulp Dryer, Energy Consumption, Energy Saving, Steam Trap, Losses Steam

Abstract

Energy requirements for household cooking needs still depend on LPG (Liquefied Petroleum Gas). However, the lack of LPG supply and poor distribution are still obstacles in the community. Biomass waste is one of the alternative fuels for society so that cooking energy needs can be met. The objective of research is to study the effect of type of biomass and biomass size on the performance of gasification stoves by using a water boiling test (WBT) analysis. The experiments were carried out in batches with two WBT phases, namely cold start and hot start. The first stage was a cold start, where the tester uses a stove at room temperature an a number of fuels to boil 2.5 liters of water in a standard pan. The second stage was called the hot start test, where water is boiled with a hot stove with the aim of identifying the difference in the stove’s power when it’s cold and when it’s hot. In addition, the flame temperature and stove operating time are the performance parameters of the stove champion gasification stove. Water content for each biomass used is between 10-13%. The resulting flame color is reddish yellow with a fire height of 30-72 cm. The maximum flame temperature produced by the stove is 806,3 oC using mahogany wood. Key words: biomass gasification, gasification stove, water boiling test (WBT).

Abstract

Oil palm trunks are agricultural solid waste that has not been used optimally. Oil palm trunks have a high starch content so that they can be used as raw materials for making bioplastics, dextrins and adhesives. The experiment of hydrolisys of starch-free oil palm trunks was intended to study the effect of time and catalyst concentration on the obtained pentoses and furfurals. Hydrolisys of starch-free palm trunks was carried out in batches on a laboratory scale. The experimental variables studied were formic acid concentration 85% by weight, catalyst concentration (0; 0.05; 0.1; 0.15; 0.2% by weight), reaction time (0; 5; 10; 15; 20; 30 . ; 45; 60; 90; 120; 180 minutes) and a solid-to-liquid ratio of 15/1. The experimental results showed that the time and concentration of the catalyst greatly influenced the pentose and furfural in the process of hydrolisys of starch-free oil palm trunks. The levels of pentose and furfural dissolved in the used cooking liquid in this experiment were pentose (0.31-1.37 grams/l) and furfural (1.45-2.95 grams) with the percentage of hemicellulose recovery ranging from (28-57% ).Keywords: palm trunk, starch-free, delignification, organosolv, formic acid
