Abstract

Solid waste produced by the palm oil processing industry consists of oil palm empty bunches (20-23%), fiber (10-12%), and shells (7-9%). Until now, the solid waste of palm fruit fiber is used as a potential energy source to be burned as boiler fuel. But along with the increase in Crude Palm Oil (CPO), there are still many palm fruit fibers that are not utilized optimally so that the waste only accumulates in the factory area, so the alternative sollution that can be done is by composting. Composting of palm fruit fiber waste with the addition of POME liquid waste which aims to determine the effect of adding Palm Oil Mill Effluent (POME) liquid waste with variations of 0%, 20%, 30% and 40% to the C/N ratio and measurements of C, N, pH, water content, and measurements are carried out. temperature, and the compost product is compared to compost quality standards (SNI 19-7030-2004). The results showed that the effect of POME addition at 20% gave the best results as indicated by the content of C/N 10.81, pH 6.99, water content 42.44% and temperature 32.06 oC, and compost product fulfill the quality standards SNI 19-7030-2004 compost. Thus, the best composting performance of palm fruit fiber waste is the addition of 20% POME with the fastest composting time at 25 days. Utilization of palm fruit fiber is one of the solutions to sustainable environmental pollution control. Key Words: Composting Process, C/N Ratio Palm Fruit Fiber, Palm Oil Mill Effluent (POME), Windrow.

Abstract

Every year the production of pulp and paper continued to increase. This resulted in the wastewater produced in large quantities. Characteristics of Chemical Oxygen Demand (COD) in the pulp and paper effluent is 3500 mg/L. COD is one of the important parameters in determining the quality of wastewater and measurement of water pollution by organic substances. High value of COD in waste water indicates that the degree ofcontamination at a higher too. Therefore, the pulp and paper wastewater treatment is necessary before it is discharged into waters. COD handling of pulp and paper wastewater can be aerobically by using the stabilization contact reactor. The aim of this study is to set aside the content of COD and determine the effect of detention time on COD removal efficiency and optimum pH of pulp and paper effluent. The results showed that the CODremoval by varying the detention time for 1 hour, 2 hours, 3 hours and 4 hours, the highest COD removal efficiency obtained at 4 hours in the amount of 87.14 % with pH of 8.0. Thissuggests that the stabilization contact reactor is stabilized in removing wastewater COD content of the pulp and paper.Keyword: Aerobic, Provision for the content of COD, Pulp and paper wastewater, Stabilization contact reactor.

Abstract

Water hyacinth is one of aquatic weeds that commonly found in water and it grows very fast. Water hyacinth contains fermentable material, named cellulose and hemicellulose and it can be potentially used as a material for bioenergy as biohydrogen. Biohydrogen was produced from water hyacinth using microoorganism derived from cow manure by anaerobic batch fermentation. This research was originally purposed to produce biohydrogen and to determine the optimum water hyacinth to water ratio in their impacts on pH, alkalinity, and volatile fatty acid. Biohydrogen production occurred in three steps: seeding, acclimatization, and anaerobic batch fermentation. Water hyacinth to cow manure ratio was 75%: 25%. Anaerobic fermentation was carried out with variations of water hyacinth to water ratio 1:2, 1:3, 1:4 and 1:5 at initial pH 6 and mesophilic temperature. The most optimum water hyacinth to water ratio in this study was 1:2 with 3.45% biohidrogen product of total biogas.Keywords: anaerobic batch fermentation, biohydrogen, cow manure, water hyacinth
