Abstract

Biogas is one of the renewable energy sources produced from the process of methanogenesis. This research was conducted to determine the optimal composition of palm oil liquid waste (POME) and cow rumen fluid to produce biogas and to determine the effect of the composition of the mixture on the volatile solid value, pH, temperature, biogas production, and flame testing. This study used 3 trial batch type digesters with a capacity of 40 L and the raw material was a mixture of palm oil mill effluent (POME) and cow rumen fluid with a composition of 3 : 1 (R1), 1 : 1 (R2) and 4 : 1 ( R3). During the treatment, pH, temperature, VS and biogas were tested. This research was conducted for 49 days. The research was conducted for 49 days and it was found that the composition of the mixture of palm oil mill effluent (POME) with cow rumen fluid which was optimal for producing biogas was found in R1 with a mixture composition of POME: cow rumen fluid as 3:1. R1 produces a volume of biogas of 1.86 L, from the flame test it can ignite from the third to the seventh week. The composition of the different mixed ingredients for each digester has an influence on the value of VS, pH, temperature, biogas production, and flame tests. The effect was on the difference in VS values, pH, biogas production, and flame test results for each digester, but for the temperature parameter the effect was not too visible because the temperature ranges for the three digesters were both in the mesophilic temperature range, ranging from 27°C - 32°C.

Abstract

This research aims to investigate the effect of spoiler usage on box trucks on the coefficient of drag. A high coefficient of drag on box trucks can result in inefficient fuel consumption and higher exhaust gas emissions. Spoilers are installed on the top of the box truck to help streamline airflow and reduce air pressure above the vehicle, thereby reducing air resistance and improving vehicle performance. Although spoilers on box trucks have been used in the logistics and transportation industry, their effect on the coefficient of drag has not been extensively studied. Therefore, this research is expected to provide information to optimize vehicle performance and reduce the negative impact of vehicles on the environment.

Abstract

One alternative to repair damage to old road pavements is with recycling technology or recycling (CTRB) where Issues with the Mixed in Place procedure include mixing with pre-existing soil material, which should not be mixed during implementation as it will impact the Unconfined Compressive Strength (UCS) values. The Conch brand is less expensive as a binder than local cement from South Kalimantan since production expenses are lower.This study aims to determine the typical influence of existing soil on UCS, what percentage of existing soil material can still be tolerated either curing or non-curing, and correlation. It also aims to obtain recommendations for the maximum percentage of influence of percent of existing land on UCS in curing or non-curing. Finally, it aims to obtain UCS Results at minimal cement levels that still meet the requirements with the use of brand local cement. RAM samples were obtained for the purpose of investigation, which was done in a lab, existing soil and additional materials in the field. Inspection of old aggregates, making test specimens with variations in cement content of 1-10%, after obtaining minimum UCS according to technical requirements then making test specimens with variations in soil examinations and content UCS’ of 0%, 5%, 10%, 15%, 20%, and 25% again then conducting data analysis to find correlations / relationships. The results of the research showed variances in cement content of 1% (one) - 10% that still meet the technical specifications of UCS (at least 30 kg/cm²) obtained a minimum cement’ content of 5% (five percent) with a UCS of 33,77 kg/cm². Then the test results of the influence of existing soil on UCS that is still tolerated are mixed, namely in curing conditions is 17% with the equation Y = - 0.10075 x + 46.894 (R2 = 0,964). and non curing 8,9% with the equation Y = - 0,1113 x + 39,814(R2=0,956). The R2 conclusions for both indicate a very There is a substantial correlation between the two factors.
