Abstract

Laccase enzyme is classified as oxidoreductase enzyme; i.e. an enzyme that can oxidize phenolic compounds and reduce oxygen molecules into water molecules. An enzyme production process using fungi through solid fermentation has more advantages compared to the one through submerged fermentation since it has the processing condition as if the fungi grow in nature. This research is aimed at investigating the process of laccase enzyme production by Trichoderma asperellum LBKURCC1 in bioreactor tray through solid state fermentation using rice straw substrates. The objective of this research is to figure out the influence of bed depth and fermenting time on laccase enzyme production by Trichoderma asperellum LBKURCC1. The variables of the research are the bed depth of 1.5, to 4.5 cm and fermentation time of 5, to 10 days. The research findings show that the peak of laccase enzyme activity was obtained at 3.0 cm bed depth and 7 day fermentation time. Increasing the depth of the bed can increase the activity of laccase enzyme produced. However, increasing too much depth of the bed can cause the decrease of laccase enzyme activity. Besides, the fermentation time over 7 days can also decrease the laccase enzyme activity for the amount of the water contained in the bed is drying up.Keywords: bioreactor tray, laccase enzyme, rice straw, Trichoderma asperellum LBKURCC1

Abstract

Flooding is a problem that almost every year affects urban and rural areas. Generally, in urban areas, floods are caused more by the lack of smooth flow of water (sewage) due to waste dumped into the water stream and the reduction of water catchment areas. The Delima Subdistrict of Tampan Subdistrict has a simple housing area that has a limited home yard measuring around 7m x13m up to 10m x 15m per house unit. To meet clean water needs, this area uses bore wells which over time will reduce underground water reserves. The housing area is sometimes disemenised, which results in a lack of infiltration of rain water so that it is prone to flooding and drought. To overcome this, the community can apply biopore infiltration technology. This service activity aims to introduce biopore infiltration technology and invites the community to apply it and make biocompost from the infiltration hole. The method of service activities was carried out with material delivery techniques and discussions as well as demonstrations or practices in making biopori infiltration holes as an effort to overcome floods and droughts in settlements around the Delima Village, Tampan District, Pekanbaru. From the results of this activity it is known that the target community seemed enthusiastic about the material presented and there was an increase in the knowledge and insights of the participants about biopori absorption technology by around 80%.

Abstract

The biopore infiltration hole is a hole with a diameter of 10 cm - 30 cm with a depth of 30 cm - 100 cm which is added with organic waste and will help soil biota form a biopore hole so that it can trap the air flowing around it. Black Soldier Fly larvae are able to accelerate composting and ordering of pores in the biopore infiltration holes. Perumahan Putri Indah Kulim RT 02 RW 12 Kelurahan Mentangor rarely finds open land semisization and house widening which causes a reduction in the surface of ground air infiltration so that during the rainy season puddles easily occur and during the dry season it reduces groundwater reserves. This activity aims to provide knowledge and insight into the community about biopore infiltration holes by utilizing Black Soldier Fly larvae and inviting the public to apply this technology. This service activity begins with the socialization of the biopore infiltration holes, then introduces the tools and materials as well as direct practice in the field. The results of this activity had a positive influence on the community and many community members who wanted to apply the biopore infiltration hole technology using Black Soldier Fly larvae. This is the first step in creating a clean and healthy environment, especially in Putri Indah Kulim Housing RT 02 RW 12 Mentangor Village.

Abstract

The shortage of availability and increasing prices of Liquefied Natural Gas (LPG) encourage some people to use firewood as an alternative to traditional cooking fuel. The utilization of conventional stoves for combustion results in the generation of carbon monoxide (CO) emissions which can be dangerous to human health. Gasification stoves produce less CO emissions than conventional stoves and produce thermal efficiencies up to 35%. The shortage and high expense of LPG can be avoided by using biomass waste, such as twigs, wood chips, and palm fronds, as fuel for gasification stoves instead of kerosene or LPG. The gasification stove used in the socialization was designed based on the dimensions of the Champion Stove Top-Lit Up Draft. Wood logs that have been cut to a size of 6–9 cm and a width of 1 cm are utilized as fuel. 1.5 liters of water were successfully boiled for nine minutes by KOMAS gasification stoves. This socialization activities attracted the attention community of Batu Belah Village and at the end of this socialization, the team gave gasification stoves to the local community as an effort to apply the technology.

Abstract

Stainless steel 316L is a metal that can be used for bone implants but exhibits low biocompatibility. The low biocompatibility can lead to inflammation, infection, or rejection within the body's tissue system. It is coated with hydroxyapatite-polycaprolactone to enhance the biocompatibility of stainless steel 316L. This study aims to examine the effects of stirring time, stirring speed, and the appropriate hydroxyapatite-polycaprolactone ratio on the shear strength of hydroxyapatite-polycaprolactone using the dip coating method and to determine the empirical model for the resulting shear strength of the hydroxyapatite-polycaprolactone layer. Hydroxyapatite and polycaprolactone were mixed using acetone and stirred at a speed of 150 rpm for 20 hours. Then, the stainless steel 316L substrate was immersed in the suspension and dried at 56°C for 1 hour. The process conditions optimization in this study employed a 2k modeling approach. The empirical shear strength model in this research is represented as y = -216.9 + 36.42A + 1.426B + 14.43C - 0.2345AB - 2.380AC - 0.08943BC + 0.01468AB*C, with an R2 value of 0.99. The variables with the most significant influence on shear strength, ranked from largest to smallest, are the HA-PCl ratio (A), followed by the two-way interaction between the HA-PCl ratio (A) and stirring speed (B), the three-way interaction between the HA-PCl ratio (A), stirring speed (B), and stirring time (C), followed by the two-way interaction between the HA-PCl ratio (A) and stirring time (C), stirring time (C), stirring speed (B), and the two-way interaction between stirring speed (B) and stirring time (C). The highest shear strength of the hydroxyapatite layer was achieved at a HA-PCl ratio of 5:1.5, stirring speed of 150 rpm, and stirring time of 20 hours, with a value of 5.71 MPa

Abstract

The Rokan Block is one of Indonesia's largest oil producers. It is managed by PT Pertamina Hulu Rokan (PHR) and contributes 25% to Indonesia's total oil production. The Central Gathering Station (CGS) “X” at PT PHR utilizes shell and tube heat exchangers (HEX) to effectively heat produced fluids, thereby enhancing the separation of crude oil. Despite their utility, several challenges—such as uneven fluid distribution, fouling, and tube plugging—have compromised the performance of heat exchangers (HEX). These issues can result in some units failing to reach the desired temperature. This study assessed the performance of HEX at CGS X using Aspen HYSYS and Aspen Exchanger Design and Rating (EDR) software, concentrating on key parameters including the heat transfer coefficient, pressure drop, and fluid velocity. The analysis revealed that low fluid velocity within the shell increased the risk of fouling, and a fouling resistance exceeding 0.03 ℉·hr·ft²/Btu significantly diminished efficiency. To address this, a redesigned heat exchanger (HEX) was proposed to optimize fluid velocity, achieving a rate of 1.15 ft/s. This adjustment reduced fouling and enhanced heat transfer while maintaining economic feasibility by decreasing the required heat transfer area. Operational recommendations based on the performance evaluation included making appropriate fluid distribution adjustments and conducting timely maintenance to ensure reliable operation
