Abstract

The Pertamina Research & Technology Centre Facility is a laboratory building designed to support research activities, where laboratory space is a critical element in the design of a research and laboratory centre. Due to activities involving chemicals, crude oil and other products, the risk of chemical and biological contamination, radiation exposure, explosions and fires is higher than in most other facilities. This potential hazard requires a well-designed building access system to prevent the risk of fire and explosion. The aim of this study is to evaluate whether the building access for fire and explosion protection in this facility is adequate and meets established standards. The evaluation method used is a qualitative approach through a literature review on the principles of fire access in buildings, which is then applied to the Pertamina Research & Technology Center facility located at Jl. Daan Mogot Km. 16, West Jakarta. The results of the evaluation indicate that the fire egress in this facility meets the established standards, allowing the occupants to conduct research activities more safely against potential fire and explosion hazards in the future.

Abstract

Private transportation is one of the main sources of emissions in Indonesia, which contributes to an increase in greenhouse gases due to excessive CO₂ emissions. This research aims to create a database of motorbike and passenger car activity, determine the CO₂ emission factor from various types of vehicles, and analyze the total CO₂ emissions from motorbikes and passenger cars in Banda Aceh. Data was collected through three survey methods: questionnaire, video, and GPS Logger. Questionnaires were distributed via Google Form to 400 respondents to determine patterns of use of motorbikes and passenger cars. Video surveys analyze traffic composition, while GPS Loggers are used to map driving conditions on Banda Aceh's arterial roads. The data obtained was then analyzed using descriptive statistics and the International Vehicle Emissions (IVE) model to calculate the emission factors for motorbikes and passenger cars in Banda Aceh City. The average Vehicle Specific Power (VSP) value for motorbikes was recorded at 1,449 kW/ton, while for passenger cars it was 1,456 kW/ton. The average CO₂ emission factor for motorbikes is 6.26 gr/km/hour per vehicle, and for passenger cars it reaches 51.54 gr/km/hour per vehicle. This CO₂ emission factor is relatively low in Banda Aceh. CO₂ emission predictions based on traffic volume show average motorbike emissions of 12.81 kg/km/hour, while passenger cars reach 72.83 kg/km/hour.

Abstract

Malahayati University (UNMAL) is a place of higher education with an increasing number of students. This results in a high number of vehicles that have the potential to increase carbon dioxide (CO2) emissions.This research aims to determine the amount of carbon dioxide emissions produced by motorised vehicles and the absorption capacity of green open space (RTH) in the UNMAL area after the Covid-19 pandemic. The number of vehicles is calculated to determine the amount of emissions using the method of traffic counting at peak hours in the morning, afternoon and evening for 6 days and calculation of carbon dioxide emissions with Microsoft Excel and carried out based on the Minister of Environment Regulation No. 12 of 2010 and literature studies are used to calculate the absorption capacity of green open space filling trees. The results of this research show that the total emissions from motorised vehicles in the UNMAL area after the Covid-19 pandemic was 36,904.36 g CO2/hour and the absorption capacity of trees in the UNMAL area was 748,006.92 g CO2/hour. Based on the results, the green open space (RTH) in the UNMAL area is still able to absorb CO2. The strategy to further optimise the absorption capacity of motorised vehicles is to maintain plants (watering, pruning and fertilising) and to carry out replanting (replacement/addition) of trees in various areas such as roads, parks, car parks and helipads.

Abstract

In today's world, technological innovations make it easier to choose doors that enhance security, such as those with digital locks that integrate biometric systems such as fingerprint scanners or facial recognition. Previous research has successfully developed a prototype smart door locking system that combines RFID technology, keypads and motion sensors. Radio Frequency Identification (RFID) technology and keypads are two key components of modern security systems. Their use can enhance security in applications ranging from door access control to storage solutions. Motion sensors are devices designed to detect movement in a given area. They work by monitoring changes in the physical environment, such as changes in temperature, sound waves or electromagnetic fields, caused by the movement of objects or people. The method used in this research is the End User Computing Satisfaction (EUCS) approach, together with the BlackBox method. EUCS is a technique used to measure user satisfaction with a system, emphasising the user's experience while interacting with the system. Based on the analysis of the evaluation results, it can be concluded that the RFID-based smart door lock system, equipped with a keypad and a sensor, meets the usability criteria and falls into the good or acceptable category for users. In addition, the black box test results show that the system is functioning as expected.

Abstract

Environmental issues related to waste management and the need for sustainable agriculture have driven the search for eco-friendly alternatives. This study explores the utilization of eco-enzyme as a coagulant and organic fertilizer. Eco-enzyme, produced through fruit peel fermentation, was tested for its effectiveness in particle sedimentation in wastewater and enhancing soil fertility. The research employed an experimental approach, using jar test for coagulation and applying eco-enzyme as a liquid fertilizer on plants. Results indicate that eco-enzyme is less effective as a coagulant due to an increase in Total Suspended Solids (TSS) and water turbidity. However, eco-enzyme made from dragon fruit peel (U3) met the liquid organic fertilizer standards with appropriate C, N, P, and K levels, significantly improving soil fertility and plant growth. In conclusion, eco-enzyme has potential as an eco-friendly organic fertilizer but is less effective in coagulation functions.

Abstract

Biomass-based products are increasingly being used in industrial applications, but these innovations require efficient pretreatment to standardise the raw materials. In this study, the characteristics of oil palm mesocarp fibres after alkali processing were evaluated. The process consisted of two stages: delignification and bleaching. The organosolv extraction method was used to increase the efficiency of delignification during the bleaching stage. The mesocarp fibres were analysed using the kappa number test, scanning electron microscopy and Fourier transform infrared spectroscopy. A decrease in kappa number was observed, indicating a lower lignin content in the mesocarp samples. The FTIR spectrum showed a decrease in the peak intensity of C=C bonds in lignin at wavelengths of 1400-1500 cm-¹. Structural changes in fibre morphology after delignification and bleaching were observed, indicating that lignin had been successfully extracted from the mesocarp fibres. Optimal conditions for kappa number reduction were obtained at a NaOH concentration of 1 M, a delignification time of 4 h and a NaOCl volume of 280 ml (28 ml/g).

Abstract

Given the significant amount of organic waste generated daily by households in Yogyakarta, a number of initiatives and strategies are being employed to achieve effective waste management. One potential solution is the use of Black Soldier Fly (BSF) larvae as an alternative to high protein fish feed. The larval residue (frass), which contains a variety of nutrients, may also prove beneficial to plants. This research was conducted from January to March 2024 at the Solid Waste and Hazardous Waste Laboratory, Islamic University of Indonesia, Yogyakarta. The aim of this study is to determine the potential of BSF larvae and BSF frass as organic waste decomposers, using three different types of feed: mixed food waste, vegetable waste and leaf waste. A comparative analysis was carried out between the data obtained by the researchers and the quality standards established in the 2022 version of SNI 9043-4 for fish feed, and Ministerial Decree No. 261 of 2019 for solid organic fertilisers. The results show that BSF larvae fed with mixed food waste meet the quality standards for protein and fat content, with values above 35% and 5% respectively. In addition, the total NPK value of the BSF frass produced is above 2% and the C/N ratio is below 25%. Frass that meets these standards is produced from larvae fed on mixed food waste.
