Abstract

The intersection of Temanggung Kanyapi Street, Wortel Street, and Seth Adji Street in Palangka Raya City is a frequent source of delays and congestion. This is due to the high volume of vehicles entering and exiting both main and minor roads. The situation is made worse by the dense activities around the intersection, such as residential areas, educational institutions, and commercial areas, which cause congestion during peak hours. This research will analyze the performance of the unsignalized intersection based on PKJI 2023 and provide recommendations for handling to improve intersection performance. Direct surveys are used to collect primary and secondary data, and key indicators such as Degree of Saturation (DS), Delay, and Queue Probability are calculated. The analysis results are clear: from Tuesday to Sunday, the DS value is ≤ 0.85, meaning the intersection is still operable. However, on Monday, the intersection's performance declines, with the DS value increasing to 0.93 (DS ≥ 0.85), indicating nearing saturation. The delay values range from 8.75 to 16.35 seconds per vehicle, with the largest delay occurring on Monday at 16.35 seconds per vehicle, which falls into category C.

Abstract

Currently, there is an increasing need for a transparent and efficient reporting system in the management of village funds (Dana Gampong), as many fund management processes still rely on manual methods or systems that are not well-integrated. Therefore, this research focuses on the development of a multi-user web-based application for reporting the use of village funds, integrated with the CodeIgniter framework. This application aims to provide a transparent and efficient system for managing and reporting village budget allocations, expenditures, and activities at various levels, including categories, fields, villages, and subdistricts. The system is designed to allow both administrators and village operators to input and manage data, ensuring accurate and up-to-date financial reporting. The admin interface enables users to update account credentials, manage categories, fields, villages, and subdistricts, while the operator interface facilitates detailed activity reporting. Additionally, the application ensures accessibility across various devices, including personal computers, laptops, tablets, and smartphones, making it flexible and user-friendly for all stakeholders. This research also explores the importance of an integrated system in improving transparency in village governance, providing a comprehensive view of fund usage across different categories and time periods.

Abstract

Composite propellants are the primary fuel in rocket propulsion systems, consisting of a binder, fuel, and oxidizer. Ammonium perchlorate (AP) has long been used as an oxidizer in composite propellants due to its high performance and optimal combustion characteristics. However, the use of AP has negative environmental impacts due to hydrogen chloride (HCl) emissions, which contribute to air pollution and the potential for acid rain. Therefore, environmentally friendly alternative oxidizers are needed to support the defense industry. This study employs a qualitative method based on a literature review to analyze alternative oxidizers such as ammonium nitrate (AN), ammonium dinitramide (ADN), hydrazinium nitroformate (HNF), and hexaazaisowurtzitane (HNIW). The findings indicate that ADN is the most promising alternative to AP due to its good oxygen balance, high specific impulse (Isp), and more environmentally friendly combustion products. Meanwhile, HNF and HNIW exhibit high performance but are less stable and more sensitive to shocks. AN is a more economical and readily available oxidizer; however, it has limitations in terms of thermal stability and burn rate. These alternative oxidizers have the potential to replace AP in reducing environmental impact while supporting the self-sufficiency of the defense industry, considering aspects of safety, energy efficiency, and environmental impact. Further research is needed to enhance the stability of ADN and develop more efficient and sustainable production strategies for alternative oxidizers.

Abstract

Rapid population growth and climate change have put pressure on water availability, leading to a water crisis. Efforts to control water resources are needed to address this. The option of using domestic wastewater treatment plant effluent has emerged as an alternative solution. In 2024, the Jambi City Wastewater Treatment Plant (WTTP) infrastructure will be constructed and operated with a capacity of 7,500 m^3/day using Moving Bed Biofilm Reactor (MBBR) treatment technology. The existing WTTP is considered to have great potential in terms of volume. However, it is still unknown how much this potential can contribute to meet the water demand of Jambi City. Therefore, this research was conducted to fill this information gap. The research was conducted using the descriptive statistics method with quantitative and qualitative approaches. The analysis of population growth projections and public facilities refers to the Minister of Public Works Regulation No. 18/PRT/M/2007. There are 5 (five) categories of water demand analysed, namely: (a) domestic; (b) general; (c) landscape irrigation; (d) agricultural irrigation; and (e) fisheries. The potential use of wastewater is obtained by comparing the existing wastewater discharge with each category and application of water demand. The results of the analysis show that the effluent from the Jambi City WWTP can contribute 100% to meet the water demand of the domestic category (public taps), public, landscape irrigation and fisheries. In contrast, the domestic category (house connections) can only contribute 11% and the agricultural irrigation category can only contribute 15%.

Abstract

Coal-fired power plants produce emissions of particulate matter and gases such as NOx, SO2 and Hg, which can have adverse effects on living organisms. Modelling is one method used to estimate the impact of an emission. In addition, the pollutant dispersion model can be used to assess the compliance of an industry's ambient air sampling points. The model used in this study is AERMOD, which is a steady state model influenced by the existing meteorological conditions. The study site is Pangkalan Susu PLTU (2x200 MW) with NOx and SO2 parameters. The purpose of this study was to analyse the distribution patterns of NOx and SO2 concentrations using the AERMOD model, to analyse the differences in pollutant distribution models in wet and dry months, and to validate the modelling with field observations. The results showed that the maximum concentration of the model was 17.4 µg/m3 for NOx and 16.2 µg/m3 for SO2. The simulation results of the AERMOD model show the impact distribution area to the southeast in the wet month and to the northeast in the dry month of the Pangkalan Susu PLTU. The validation results show that the model is in agreement with the field observations.

Abstract

Building on peat soils often causes problems, one of which is significant settlement. Local people often use wooden foundations on peat soils, but they may not be able to support the load. This study proposes to modify the timber foundation by incorporating steel strip plates and sand amelioration, which will be simulated using software and subjected to laboratory testing to evaluate the effect of incremental loads on settlement. Peat soil samples were collected from Jalan Bukit Raya XIV, Palangka Raya for laboratory analysis of their physical and mechanical properties. Plaxis 2D software was used for the modeling analysis. Field loading continued until settlement reached the SNI 8460: 2017 allowable threshold of 2.5 cm. The soil test results were as follows: moisture content = 580.51%; fiber content = 33.12%; ash content = 4.64%; bulk density = 1.06 g/cm³; specific gravity = 1.79; cohesion = 0.0023 kg/cm²; angle of internal friction = 2°. The software analysis results indicate that modifying the hardwood base with three steel strip plates is the most effective method for load resistance. The load at 2.5 cm settlement is 340 kg from the load test and 350.5 kg from the Plaxis 2D analysis.

Abstract

Al-MCM-41 can be synthesized using kaolin from Bangka Belitung without requiring additional sources of silica or aluminum. The process begins with calcination of kaolin to produce metakaolin, followed by HCl treatment for dealumination, which helps remove impurities and excess alumina. This step is crucial to achieve the optimal SiO₂/Al₂O₃ mole ratio, making the material effective as an adsorbent or catalyst. The hydrothermal process enhances silica polymerization and pore formation due to the strong electrostatic interactions between CTAB and silicate anions, increasing the pore size. The mesoporous structure and SiO₂/Al₂O₃ ratio of Al-MCM-41 are influenced by the CTAB concentration and the extent of dealumination through HCl treatment. In this synthesis, CTAB acts as a structure-directing agent, forming the hexagonal mesoporous framework, while HCl concentration regulates the removal of alumina from kaolin. To optimize the process, HCl concentrations of 2M, 4M, and 6M were tested to evaluate the extent of alumina and impurity removal. The 6M HCl treatment produced a SiO₂/Al₂O₃ ratio of 25.359, which aligns with the commercial Al-MCM-41 standard from ACS Material. Additionally, the iodine adsorption test demonstrated significantly higher adsorption capacity (653.14 mg/g) for Al-MCM-41 compared to kaolin (76.2 mg/g).
