Abstract

Coal is the main fuel used to make clinker in the cement industry. As time goes by the cost of purchasing coal is getting higher and supplies are running low, making it necessary to optimize to reduce production costs. To deal with this problem, high-quality coal is mixed with low-quality coal (lignite coal) using the Chevron method. The Chevron method is a method of stacking coal continuously along the pile axis and moving horizontally in a predetermined area. The coal is stacked in layers with layers of low-quality coal (lignite coal) and high-quality coal alternately according to the lignite coal mixture ratio. The specified ones are 30%, 40%, 50% and 60%. The optimum mixture ratio of low-quality coal (lignite coal) is 60%, which can reduce the cost of purchasing coal by IDR. 486,899 per ton. Daily consumption of coal for burning clinker is around 1000 tons per day so the efficiency of coal purchasing costs reaches around 14.6 billion rupiah per month while maintaining the quality of the clinker produced with a free CaO range of 1.04 – 1.40%, below the Indonesian National Standard (SNI ) namely 1.50%.

Abstract

Studies on hydrocracking of nyamplung oil into biofuel have been studied using the HZSM-5 catalyst. The HZSM-5 catalyst was modified into HZSM-5 mesopore and impregnated using transition metals namely Cobalt, Nickel and Cuprum with a metal loading of 5% and a metal ratio ratio of 1:1:1. The resulting catalyst was then characterized using X-Ray Difraction (XRD), Brunauer Emmet Teller (BET), and Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX). The hydrocracking process was carried out in a batch reactor by adding 0.5 grams of catalyst and a volume of Nyamplung oil of 15 mL. The temperaturs used vary from 250, 300, and 350 oC with a hydrogen gas pressure of 20 bar, and a reaction time of 2 hours. The resulting biofuel product is analyzed using Gas Chromatography Mass Spectrometry (GC-MS). The resulting biofuel product has a compound composition of n-paraffin with an area % of 26.72%, cycloparaffin 3.34%, olefin 0.33%, aromatic compounds 15.83% and polycyclic aromatics 12.56%, with a conversion of 72.1% in temperatur 350 oC. Biofuel from nyamplung oil can be used as an alternative fuel to reduce dependence on fossil fuels through the hydrocracking process.

Abstract

Every year, millions of tons of construction waste are produced, including wire mesh that is often left unused from the cutting and installation processes. Wire mesh, which serves as a reinforcement for concrete, frequently ends up as waste. With the increasing amount of construction waste, this research proposes the utilization of wire mesh as a partial substitute for fine aggregate in concrete mixtures with variations of 0%, 5%, 7.5%, and 10% by weight of sand, targeting compressive strengths of 21 MPa and 25 MPa. Additionally, 8% fly ash and 0.5% superplasticizer by weight of cement were used. Test specimens were cylindrical, with a diameter of 15 cm and a height of 30 cm, and were tested for compressive strength after 28 days. The results showed an increase in compressive strength of 36% and 9% for concrete grades of 21 MPa and 25 MPa, with the optimum percentage of wire mesh addition being 5%, which resulted in compressive strengths of 33.20 MPa and 31.73 MPa, respectively. However, the compressive strength significantly decreased at the 10% wire mesh variation, with average compressive strengths for the target grades of 21 MPa and 25 MPa being 23.67 MPa and 16.43 MPa, respectively.

Abstract

The use of the Manual Kapasitas Jalan Indonesia (MKJI) 1997 as a guideline for the design and evaluation of a road or intersection in Indonesia, after being used for approximately 26 years, was finally updated with the issuance of the Pedoman Kapasitas Jalan Indonesia (PKJI) 2023. The object of this research is the BRI KC Kandangan Four-Way Intersection located on Panglima Batur Street, S. Parman Street and Merah Johansyah Street, Kandangan City. As one of the vital intersections that is part of the Trans Kalimantan route, this junction often experiences traffic congestion at certain times due to the influence of traffic volumes during peak office and school hours. Furthermore, this area serves as an intersection leading to the banking and market areas. The objective of this research is to calculate traffic volume, intersection capacity, degree of saturation, delay and level of service at the BRI KC Kandangan Unsignalized Four-Way Intersection. The data collection methodology for this study involves direct field surveys to obtain the required data, followed by calculations using the guidelines from MKJI 1997 and PKJI 2023.

Abstract

As a major city in South Kalimantan Province, Banjarmasin has a high population density of 6,769 people per square kilometer and a high level of mobility, with an average of 197,756 vehicles entering and exiting the city. This demands the provision of quality public services—particularly in the transportation sector. To meet these needs, the Banjarmasin City Transportation Agency must ensure the availability of adequate transportation infrastructure, such as piers, river shelters/stops, and public transportation stops, supported by effective asset management. One approach to enhancing this management is through the use of Geographic Information Systems (GIS) for mapping transportation infrastructure. Quantum GIS (QGIS), an open-source and freely available software, is used for spatial data processing. Mapping data indicates that North Banjarmasin District has the highest concentration of transportation infrastructure, with 18 units. Out of the total 63 transportation infrastructure units in the city, 16 are owned by the South Kalimantan Provincial Government. The use of GIS provides a strategic solution for managing transportation infrastructure assets, enabling better monitoring, planning, maintenance, and inventory control.

Abstract

In road construction projects in Kapuas Regency, differences in UCS (Uniaxial Compressive Strength) values are often found between CTB samples that remain in the cylindrical molds and those that have been removed, even though they originate from the same mixture. A similar case occurred in the Kapuas–Mandomai project in 2024, where there was a significant discrepancy in UCS values. This paper aims to share experiences regarding CTB compressive strength testing results and emphasize the importance of evaluating the factors contributing to UCS reduction as a consideration for future projects.CTB work in this area is typically carried out after the spreading and compaction of Aggregate A with a width of 5.5 meters and a thickness of 30 cm, as planned. Next, cement is spread on the road surface at a 5% content based on the job mix design and offer analysis, then mixed using a recycling machine and water tanker moving simultaneously until a homogeneous mixture is achieved. The water tanker functions to add the required moisture content. After mixing, the material is shaped and compacted.For laboratory testing, five cylindrical samples were taken—three tested on the first day and two on the second day. The results showed UCS values of 38.09 kg/cm² and 45.25 kg/cm², respectively. This variation is suspected to be caused by uneven cement distribution and sample disturbance when removed from the mold. The use of a cement spreader is recommended for more uniform cement distribution, along with matching the number of samples with the available molds. Further research is needed to gain deeper insight into the causes of CTB quality reduction in the field.

Abstract

Based on the reference field used, there are two known geodetic height systems: the geometric geodetic height system and the physical geodetic height system. Several types of height are recognized, including normal height, orthometric height, and dynamic height. Elevation data from the national digital elevation model (DEMNAS) will be supplemented with field leveling (waterpass) measurements to obtain elevation values at the survey control points in the area. The differences between field data and DEMNAS data will be calculated to determine the discrepancies in orthometric height at those points. The report was prepared using data processing methods from field measurements conducted in the survey area. The research focuses on determining the orthometric height at benchmark points within the study location, which is in Binuang, Tapin Regency, South Kalimantan. Leveling was carried out using a round-trip method corrected according to Indonesian National Standards (SNI), resulting in elevation data. In addition, GNSS observations were conducted using geodetic GPS with the static method to obtain corrected coordinates and orthometric height. Data from DEMNAS was processed using ArcMap 10.3 software to produce interpolated elevation values, such as at BM 04, which showed a height of 3.303 meters. By comparing DEMNAS data and field survey data, differences in elevation were found between BM 18 and BM 22. The discrepancies were as follows: BM 18 = -2.160 meters and BM 22 =-0.682 meters.

Abstract

Utilization of waste as an energy source for Waste-to-Energy Power Plants is an implementation of Waste to Energy (WtE). This research begins by calculating the potential waste generation in each province in Indonesia based on data from the National Waste Management Information System in 2024 and the projected waste generation in 2025. The calculation is based on the assumption that every 1000 tons/day of waste has the potential to be converted into energy of 20 MW. The results of the calculation of electrical power from the potential waste generation in 2025 of around 60-65 million tons obtained electrical power of around 3,655 MW or 3.655 GW. Based on the volume of waste generation in each province, the potential for electrical power is divided into 5 (five) categories, namely the Very Large category for West Java and East Java with an electrical power of 350-500 MW, the Large category with a power of 160-350 MW in DKI Jakarta and Central Java, the Medium category in Banten and South Sulawesi with an electrical power of 60-180 MW and the Small category with a potential electrical power of 20-60 MW in Aceh, North Sumatra, Riau, West Sumatra, South Sumatra, Lampung, DI Yogyakarta, Bali, NTB, NTT, West Kalimantan, Central Kalimantan, South Kalimantan, East Kalimantan and North Sulawesi. The remaining 17 of the 38 provinces are in the Very Small category with an electrical power of only 0-20 MW. The number of PLTSa that has the potential to be built is around 34 units, namely 5 units in West Java, 4 units in East Java, 3 units in DKI Jakarta and Central Java, 2 units in Banten and South Sulawesi and 1 unit each in 15 provinces with a small category power.
