Abstract

Sodium chlorate (NaClO3) is used to produce clorine dioxide (ClO2), which is used in the bleaching process in the pulp and paper industry. Sodium chlorate is produced in the industry by electrolysis process. This electrolysis process produces 2 main products, namely hydrogen and sodium chlorate. hydrogen is used in the process of making hydroclorid acid (HCl) and sodium chlorate is used in the process of making ClO2. In the process of making chlorate there are several things that must be considered, including: pH, oxygen levels in the degasifier, conditions of the hypo tower system, salt and chlorate concentration, and K cell factor. Based on the results of the above analysis, it can be seen that the acid wash cell is able to reduce the K factor of the cell. Do not run the electrolyzer if the cell voltage is above 3.5 volts. This is because at a voltage above 3.5 volts oxygen formation occurs, if oxygen meets hydrogen gas from electrolysis can cause an explosion.

Abstract

The health center that has the highest prevalence of stunting in Sleman Regency is the Minggir health center at 13.15%. The results of interviews with nutrition officers for toddlers at the Minggir Health Center showed that there were still toddlers with poor nutritional status. In addition, the nutrition service system for toddlers has not functioned properly.  Because such suboptimal performance will, it is easier to create a system that can handle or minimize such problems. Thus, building a decision support system can be a solution to the problem that occurs. The SAW method is one of the methods used and the system is designed using the PHP programming language, MySQL database and  laravel framework. The research resulted in the creation of a website that can determine the nutritional status of stunted toddlers at the Minggir Health Center Posyandu. This system is designed according to the needs based on the criteria that have been set by the nutrition officer. In the application test, the preference values and nutritional status results obtained from calculations using the system were in accordance with the results of manual calculations with Excel and the nutritional status determination system was as expected.

Abstract

Level crossings between roads and railway tracks in Indonesia still face significant safety challenges. According to the Indonesian Minister of Transportation Regulation Number 94 of 2018, an automatic early warning system without guards is required. Some locations, such as those under the supervision of the Madiun Service Unit and the Class 1 Surabaya Railway Technical Center, have been equipped with systems made by PT Wantech, but many are non-functional. This study aims to create a microcontroller-based early warning system using LoRa and SMS Gateway technology as a temporary replacement. Using the waterfall method and mean absolute error, this study compares the HC-SR04 and HY-SRF05 ultrasonic sensors. The results show that HY-SRF05 is superior in detecting trains, with an average data transmission time of 2.5 seconds for distances up to 1.5 km using LoRa, and the SMS Gateway successfully sent warning notifications at the same distance. This system is expected to improve the safety of road users and train journeys

Abstract

This research conducts a techno-economic analysis of a green hydrogen system in Lombok, Indonesia, using a MATLAB Simulink-based simulation model. The primary objective of this study is to evaluate the long-term economic feasibility of a green hydrogen project through the analysis of key financial parameters such as Net Present Value (NPV), Internal Rate of Return (IRR), and the break-even point. The model simulation results show that the production output of green hydrogen is 121,391 kg, and the project generates a Net Present Value (NPV) of $1,205,031.1 over a 25-year operational period. The Internal Rate of Return (IRR) of the project reaches 11.9%, indicating that the project has a promising profit potential. Additionally, the break-even point is achieved in the 8th year, meaning that the initial investment can be recouped by that time. These findings provide an initial overview of the economic prospects of green hydrogen development in Lombok and demonstrate the potential of green energy in supporting the energy transition in Indonesia. This study also offers guidance for policymakers and investors in making strategic decisions related to investments in renewable energy technology.

Abstract

The traffic on the Makassar City Boulevard Road segment operates using a two-way system, with a significant volume of vehicles and frequent obstacles on the sides. It arises as a result of the presence of commercial zones, encompassing trade and service establishments such as offices, banks, stores, restaurants, hotels, and shopping centers, where transactions between sellers and purchasers take place. Hence, this study was carried out to investigate the influence of side barriers obstructions on the performance of the Makassar City Boulevard Road segment utilizing the MKJI 1997 methodology. The analysis reveals that the highest frequency of side barriers on the section of Jalan Boulevard Makassar City occurs on Thursdays at point 2 (in front of Jims Honey Store), with a rate of 592 pcu/h or 4.10% of the total number of side barrier events at that location, which is 14450 pcu/h. These side barriers are classified as high class (H) and are predominantly found in commercial areas with high roadside activity. Thus, it has been demonstrated that side barriers have a notable influence on the performance of the Makassar City Boulevard Road portion, leading to a fall in speed and capacity, as well as a decline in service quality standards.

Abstract

The Central Sulawesi – Lamonae – Landawe border section is designated as a national route that links the Southeast Sulawesi region with Central Sulawesi, specifically the mining industrial district of Morowali City. This route facilitates not only community mobilization but also the transportation of heavy mining equipment. Daily, the road endures heavy vehicle traffic carrying logistics, which increases the volume and load on this route, leading to pavement layer damage and a decline in service quality. This study aims to analyze the road surface conditions and determine the appropriate handling program using the Surface Distress Index (SDI) and International Roughness Index (IRI) methods, spanning from STA 0+000 to STA 5+500 over a segment length of 5.5 km. Subsequently, it plans the pavement layer thickness design for segments with severe surface damage using the 2017 Pavement Design Manual. The study results indicate that, according to the SDI method, 47% of the road is in good condition, 24% in moderate condition, 16% in minor damage, and 13% in severe damage. According to the IRI method, 27% of the road is in good condition, 49% in moderate condition, 15% in minor damage, and 9% in severe damage. Based on SDI and IRI values, a handling program comprising routine maintenance, periodic maintenance, and reconstruction is established. The pavement layer thickness calculation, based on the 2017 Pavement Design Manual, recommends asphalt pavement with granular base layers, comprising AC WC with a thickness of 40 mm, AC BC with 60 mm, AC Base with 80 mm, and Class A Granular Base with a thickness of 300 mm, along with subgrade improvement with a planned thickness of 200 mm.
