Abstract

This community service initiative aimed to empower Islamic boarding school students and local farmers in Lempake, Samarinda, through the transfer of innovative biochar production technology utilizing biomass waste. The target community faces significant challenges, including poor soil fertility, land degradation from post-mining activities, and underutilization of abundant organic waste. The introduced biochar technology employs a simple pyrolysis process using Kon-Tiki Kilns to convert agricultural residues into porous, carbon-rich material, enhancing soil structure, nutrient retention, and water-holding capacity while reducing reliance on chemical fertilizers. The Program activities included field observations, awareness campaigns, hands-on training, technology demonstrations, mentoring, and evaluation, with Pesantren Rahmatullah serving as a strategic hub for education and local innovation. The results showed significant improvements in participants' knowledge and skills in producing and applying biochar, stimulating community-based business opportunities, enhancing soil.

Abstract

The research with the title Application of Fire and Gas Detection Systems takes place at the North Field Expansion Project (NFXP). The methods used are direct observation, interviews, simulations and literature studies. The objectives of the study were to determine the application of fire and gas detection systems, and to determine the challenges in the application of fire and gas detection systems in the North Field Expansion Project (NFXP). The results obtained show that the Fire and Gas Detection System implemented at NFXP is in compliance with international safety standards, and the system is able to detect fire threats and gas leaks with high efficiency through advanced detector technology, automatic response, and integration with other safety systems such as IPS and HVAC. The effectiveness of the system is reflected in the ability to detect threats in less than 5 seconds, with detection coverage that meets the target of 90% by one detector and 85% by two or more detectors. The main challenges in the implementation of fire and gas detection systems include extreme environmental conditions, such as corrosion due to exposure to seawater and high temperatures, and false alarms that reach around 15%. Another obstacle is the lack of technical training for personnel in operating and maintaining the system.

Abstract

The research was conducted in the construction department which has around 90 employees with a high workload and a less supportive work environment. The problem in this study is how the workload and work environment affect employee productivity, while the purpose of the study is to determine the effect of workload and work environment on employee productivity. The method used in the study is the multiple linear regression analysis method with a sample of 65 employees. Testing was carried out using the F test and t test and calculating the determination factor. From the results of the t test calculation, the calculated t-value for X1 (workload) was obtained in succession of 3,743 and the calculated t-value for X2 (work environment) was 6.187. These values ​​are greater than the value in the t-table of 1,999, which means that the workload affects employee productivity and the work environment affects employee productivity.The result of the F test calculation produces 14,872 > from the value in the F-table (3,143), it can be concluded that Workload (X1) and Work Environment (X2) have an effect on Employee Productivity (Y) at PT. Putra Tunggal Mandiritama. From the determination coefficient test, the Adjusted R Square value is 0.455 or 45.5%, meaning that the work productivity variable is influenced by the workload and work environment variables by 45.5%. Furthermore, the remaining value of 54.5% is caused by other factors.
