The Colo Timur Irrigation Area covers 20,601.80 hectares with a main canal length of 64.15 km, passing through the regencies of Sukoharjo, Karanganyar, Sragen, and Ngawi. The water flow comes from the Wonogiri Serbaguna Dam, which is dammed by the Colo Weir in Sukoharjo. This irrigation area faces issues with uneven water distribution, and there is a need to check the water irrigation from the intake gates to conclude whether the operation and maintenance of the irrigation network are in accordance with standards. The study was conducted on the secondary canals of Geneng, Pulosari, and Krikilan, which are located upstream, midstream, and downstream, respectively. On the Geneng secondary canal, measurements were taken at B CT 5, Ge 1, and Ge 8 Ka. On the Pulosari secondary canal, measurements were taken at B CT 29, BPo 1, BPo 12 Ka, and BPo 12 Ki. On the Krikilan secondary canal, measurements were taken at B CT 40, Kk 1 Ka, and Kk 1 Ki. This study uses the Ratio of Water Distribution Implementation (RWDI) to determine the category of water distribution. The water discharge from the intake gates does not match the allocated water discharge. Factors causing the discrepancy in water discharge include (a) intake gates not being opened according to plan, (b) the presence of water pumps in the canals reducing irrigation water, and (c) the field operation system implementing water distribution rotations.

Pengaruh Perbandingan Na2SiO3 dan NaOH (0,5-1,5) pada Kadar Aktivator 0,43 terhadap Toughness Beton Geopolimer
Authors: Muhammad Hayyu ‘Alam
Published: September 2024

Concrete typically consists of coarse aggregate, fine aggregate, cement, and water. However, cement production generates significant carbon dioxide emissions nearly equivalent to the tons of cement produced. One alternative to conventional concrete, which replaces cement as a binder, is geopolymer concrete. Geopolymer concrete utilizes fly ash or other materials containing silica and alumina as the binder. Unlike cement, which forms a binder through hydration, geopolymer concrete uses a chemical reaction with alkali activators such as Na2SiO3 (sodium silicate) and NaOH (sodium hydroxide). This study investigates the toughness of geopolymer concrete using cylindrical specimens measuring 15 cm x 30 cm with varying Na2SiO3 to NaOH ratios of 1:0.5, 1:1, and 1:1.5, cured at room temperature for 28 days. The study results show that the highest toughness was achieved with a sodium silicate to sodium hydroxide ratio of 1.5, yielding 2.7394 x 105 J/m3. Meanwhile, the toughness values for sodium silicate to sodium hydroxide ratios of 0.5 and 1.0 were 2.3748 x 105 J/m3 and 2.5821 x 105 J/m3, respectively. Thus, increasing the sodium silicate to sodium hydroxide ratio from 0.5 to 1.5 at an activator content of 0.43 affects the toughness of geopolymer concrete.

Published: September 2024

This study aims to redesign the superstructure of the Sambungrejo Bridge in Sidoarjo, which has a span length of 16 meters. The Sambungrejo Bridge originally used WF 700.300.15.28 steel girders and C 300.100.10.16.8 diaphragms,that are susceptible to corrosion, especially during floods. The redesign involves replacing the steel girder with a Prestressed Concrete I Girder (PCI Girder) H-900mm, 170mm thick, produced by WIKA Beton, known for its superior corrosion resistance and construction efficiency. The research methodology includes structural analysis using Robot Structural Analysis Professional (RSAP) software, calculation of prestressing forces, and the design of the prestressing cable layout. The results of this study demonstrate that the use of PCI Girder does not reduce the structural dimensions of the bridge but also proves to be more compatible with the flood water conditions at the site. The total cost required for implementing the new bridge superstructure design is Rp. 4.372.201.

Waste management poses an inevitable challenge in human life and is often poorly handled. One type of waste causing significant issues is solid organic waste from households, which can lead to unpleasant odors and soil and water pollution due to its high organic content. However, the potential of organic waste to be converted into biogas, as an alternative energy source, can be harnessed through anaerobic processes. In this experiment, the researchers aimed to observe the effectiveness of adding additives to organic waste with varying doses. The organic content in the substrate for anaerobic microbes was represented by VS (volatile solid), with the inoculum sourced from cow dung. The experiment results indicate that adding NPK fertilizer additives with different doses increases biogas production. This suggests that the use of NPK additive can enhance the efficiency of anaerobic processes in generating biogas from organic waste.

Drilling is an essential operation in mining activities, particularly in borehole preparation for blasting purposes. The efficiency of blasting hole preparation depends significantly on the drilling speed to penetrate the rock formations.Drilling Rate Index (DRI) measures the ease or difficulty of drilling through rock formations. It combines two tests: Brittleness (S20) and SJ value. DRI serves as a common metric to predict drilling capabilities and is classified according to a table classification of drilling rate index.The classification of DRI values for sandstone and mudstone of Balikpapan Formation at PT. RCI Job Site ABK indicates a very high classification with DRI values ranging from 66 to 86. Testing results for samples SBP1 (DRI 75.9), SBP2 (DRI 81.7), SBL1 (DRI 66.6), and SBL2 (DRI 71.1) all fall within the very high classification range.

The activity of dismantling shale sometimes does not align with the rating of the shale itself. Although shale generally has low durability, some types of shale exhibit considerable strength. Therefore, if the tools used are not suitable, the excavation process becomes inefficient. One shale classification method proposed by Franklin (1982) is by determining the value of slake durability index, plasticity index, and point load index. If the slake durability value exceeds 80 percent, testing continues with point load testing. However, if the slake durability value is below 80 percent, then liquid limit and plastic limit tests are conducted to obtain its plasticity index. This study is applied to the Kampungbaru Formation at PT Bintang Prima Energi Pratama. The shale testing results of the Kampung Baru Formation at PT Bintang Prima Energi yielded slake durability index values below 80 percent, thus the shale ratings based on slake durability index and plasticity index values, for KB1BL1 are 4.2; KB1BL2: 3.5; KB1BL3: 2.55; KB1BL4: 3.35; KB1BL5: 3.15; and KB1BL6: 3.65. With an average shale rating value of 3.57. The excavation tool used for these rocks is a backhoe.

The high competition in the property industry requires companies to maintain high occupational safety and health (K3) standards. Data from the engineering division of PT Gaia Care International shows that in the period January-November 2023 there were 11 work accidents, with the majority being minor accidents and one fatal case. This study aims to identify potential risk hazards, analyze risk levels, and determine appropriate risk control measures.  The HIRARC method is used in three stages: Hazard Identification, Risk Assessment, and Risk Control. The results showed that there were various potential hazards such as electrocution, falling from stairs, and exposure to chemicals. The risk assessment classified 5 work activities as low risk, 43 as medium risk, and 2 as high risk and no extreme risk was found. Risk control efforts are carried out using fishbone diagrams and 5W+1H techniques to reduce or eliminate existing risks.  This research is expected to provide benefits for companies in reducing the number of work accidents and become a reference in implementing better OHS policies, as well as providing additional insight for readers regarding the importance of risk analysis in creating a safe and healthy work environment.

This research aims to analyze personality and communication styles in business negotiations. By examining various personality types such as extraverted, introverted, agreeable, conscientious, and neurotic, this study explores how personality characteristics influence communication strategies in the negotiation process. Through surveys and in-depth qualitative analysis of business professionals, the research found that individuals with extraverted personalities tend to be more proactive in taking initiative, whereas introverts are more inclined to deliberate carefully before acting. The communication styles employed also vary based on individual personalities. This research indicates that a deeper understanding of the role of personality in business communication can enhance negotiation effectiveness and improve final outcomes. The practical implications of these findings underscore the importance of adapting communication strategies based on the personality characteristics of negotiation participants to achieve success in dynamic and complex business environments.

Every company that carries out production activities needs a supply of raw materials. With the availability of raw materials, it is hoped that industrial companies can carry out the production process according to consumer demand. In addition, adequate supplies of raw materials in the warehouse are also expected to improve the smoothness of production or service to consumers, as well as prevent shortages of raw materials. This research aims to identify and analyze the inventory management of raw materials implemented by the National Tofu Factory. The research method used is descriptive, with analysis using the Economic Order Quantity (EOQ) method. The data collected is in the form of interview results as primary data. The results of the research show that the management of raw material inventory by the National Tofu Factory has not been optimal. Based on the EOQ calculation, the amount of existing raw material inventory is smaller than what is recommended by the EOQ method. Therefore, additional raw material supplies are needed to support the smooth production process. The National Tofu Factory is also advised to provide adequate warehouses to store raw material supplies, especially for soybeans, so that they can accommodate more raw materials and reduce ordering costs.

In simplifying the process of monitoring the temperature of electric vehicle batteries, especially in discharging conditions, a remote electric vehicle battery temperature monitoring system was created. The problem with the previous monitoring system was that there was no electric battery temperature monitoring system, so users could not monitor the temperature condition of the vehicle battery when in use. The purpose of this study is to design an Internet of Things (IoT)-based electric vehicle battery temperature monitoring device system using the web and add a data logger to monitor battery temperature remotely and find out the difference in temperature values from the device with a thermogun. And the addition of a cut off feature when the battery overheats as one of the safety.
The research method uses experiments, namely by comparing the speed between 30km/h and 50km/h and comparing the readings of the monitoring device with a thermogun. In proving the performance of the monitoring equipment, it is carried out with a distance of 1km, 2km, and 3km and in sloping road conditions. The data obtained were then analyzed using the paired T-test method. The results of the study showed that the tool worked quite well with the highest error value of 3.88%. And the battery temperature value between the speed of 30km/h and 50km/h is a significant difference with a P-value result of 0.035 which means that H0 is rejected and H1 is accepted.
