The Stability

AC-BC coating is one type of hot mix asphalt with a minimum thickness of 4 cm. The most important characteristic of this mixture is the stability of the surface layer where the surface layer must be able to accept all types of work loads. As a foundation layer, the asphalt content it contains must be sufficient so that it can provide a waterproof coating. The aggregate used is rather rough compared to the surface wear layer. The aggregate requirement that dominates in the asphalt mixture makes us research what materials can be used as a mixture in the asphalt mixture. Palm oil waste provides an alternative opportunity as a material making up the asphalt mixture. The intended waste is oil palm shell which can be used as a substitute for coarse aggregate in asphalt mixture. The purpose of this study is to obtain the ACO BC mix KAO calculation without using an oil palm shell and using a palm oil shell with variations of 2.5%, 5%, 7.5%, 10%, 12.5%, and 15% as substitution of coarse aggregate and know the effect of adding palm shells to the mixture of test specimens on Marshall parameter values. Before the manufacture of test specimens, the materials are tested in advance in accordance with the 2010 Revised 3 General Specifications. 3. The addition of oil palm shells to the asphalt mixture showed an increase in KAO value. Based on the results of the study, the oil palm shell was suitable as an additive to the Asphalt Concrete-Binder Course (AC-BC) mixture because it met the requirements of the 2010 Revised 3 General Bina Marga General Specifications.Keywords: mixture of AC-BC, oil palm shells, KAO, Marshall parameters

The addition of oil palm shell ash to the concrete asphalt layer mixture in this study is an effort to use waste from palm oil production (MKS) so that the resulting waste is as minimal as possible without waste. The aim is to determine the value of the strength (stability) and durability (durability) of the mixture of asphalt concrete (Laston). The results of the stability test (strength) of the addition of palm shell ash with an average of 5% = 957.52 Kg, 10% = 1,599.37 Kg, 20% = 1,498.98 Kg, 30% = 803.28 Kg and 40% = 888, 40 Kg.  The value of durability test (durability) for the addition of palm shell ash on average 5% = 71.84%, 10% = 74.44%, 20% = 107.12%, 30% = 77.18% and 40% = 84.81 KgKeywords: Palm Shell Ash, Stability, Durability, Laston

The palm oil processing industry in which produces Crude Palm Oil (CPO) generally uses boilers. The combustion process with a boiler will produce pollutants in the form of particulates (dust), and gases such as NO2 and SO2. There are two palm oil processing industries in Muaro Jambi District that use different fuels: coal and oil palm shell. The purpose of this study was to determine the ratio of SO2, NO2 and particulate concentration in industries that use coal and oil palm shell.  Primary data taken in the form of concentrations of SO2, NO2 and particulates also meteorological data. Secondary data taken in the form of map area, height and diameter of the boiler, and production capacity. Sampling time is in the morning, afternoon and evening which is repeated in 3 times. The results showed that the comparison of NO2 and SO2 concentrations produced from coal-fired boilers was higher than shell-fired boilers, but both were still below the quality standard. Particulate concentrations in the palm oil processing industry that use coal-fired boilers are above the quality standard, while shell-fired boilers still meet quality standards.

Oil Palm Shell

Oil palm shell (OPS) is a biosolid waste in palm oil industry in the tropical countries which could be used as aggregate in concrete mixture. Since 1984, OPS has been experimented as natural lightweight aggregate in research studies to produce lightweight concrete (LWC). Medium and high-strength LWCs using OPS as coarse aggregate were successfully produced. However, higher drying shrinkage and lower mechanical properties for concretes containing higher volume of OPS are reported in previous studies. Therefore, OPS is not fit to be used as full coarse aggregate in concrete mixture and therefore, there should be an optimum OPS content in concrete. In this study, in a normal-weight concrete, normal coarse aggregate was replaced with OPS from zero to 100% with an interval of 20%. Tests such as slump, density, compressive strength in different curing conditions, splitting tensile strength, initial and final water absorptions, and drying shrinkage of cured and uncured specimens were conducted to find out optimum OPS content in concrete. From the test results, it could be summarized that OPS content should not exceed 60% of total volume of coarse aggregate.

The Impact

In the search of alternative materials for the replacement of conventional coarse aggregate, the feasibility of utilizing agricultural waste products was looked into in the effort of producing a more environmentally friendly and less dense concrete. Mechanical properties of partially substituted coarse aggregates using oil palm shell (OPS) in a concrete composite reinforced with a low volume fraction of coconut fibre (CF) have been studied for its feasibility as an alternative solution to the problem. Analysis on the impact of compressive strength, flexural strength, density and Young’s modulus have been conducted on hardened coconut fibre reinforced concrete (CFRC) at 15% and 25% substitution by volume of conventional coarse aggregates with OPS. The properties of the composite concrete were evaluated with reference to the control sample, CFRC reinforced with 0.2% fibre volume fraction. The results have shown that it is feasible to produce a sustainable grade 30 concrete of lower density with CFRC at 25% level of OPS substitution.
