Traditional materials are often selected and used in the construction of houses and buildings based on local knowledge that has been tested for centuries. The use of sago leaf stalks as a building material has several advantages. They are generally easy to find in tropical areas and have natural properties that allow good air circulation, thereby helping to keep the indoor temperature cool. In addition, this material is also environmentally friendly because it can decompose properly and can be renewed naturally. In an effort to preserve these cultural and traditional values, we can take several steps. First, public education and awareness about the advantages of traditional building materials need to be improved. Organizing workshops or seminars to share knowledge about the use of traditional materials and their benefits can help increase people's appreciation of these materials. The use of sago stalks as building materials can be part of cultural conservation and environmental preservation efforts. By combining traditional knowledge with modern innovation, we can create building solutions that are environmentally friendly, sustainable and maintain our cultural heritage. By using PVAc filler, this study aims to study its effect on the physical properties of the resulting composite material. Variations in the composition of the mix will enable the identification of changes in the characteristics of the composite board and efforts to obtain optimal physical properties.

Quality control of the train braking system is a critical aspect of ensuring the safety of many train passengers. This study aims to analyze the factors that will influence the failure of the train braking system, especially the problematic braking components, to improve the quality standards of the train braking system. The Failure Mode and Effect Analysis (FMEA) method is proposed to identify potential causes of failure—train braking systems. The main components of train braking, critical systems, failure modes, and causes of failure are analyzed, and preventive measures are suggested to reduce the impact of the failure. The results showed that the highest cause of failure of 49% was the failure of the braking system components in the control valve with an RPN value of 720, which could cause the brake block to bind so that leaks could occur, and the brake system would not work.

The increasing use of electricity encourages electricity scientists to create or build mathematical models to improve the quality of electric power. This study uses IEEE 26 bus system data to validate the method and 150 kV thermal generator data from the South Sulawesi (Sulbagsel) system as a case study. The method used is PSOHIC. The simulation results for the 150 kV Sulbagsel system data show that PSOHIC converges more quickly, namely in the 8th iteration. The standard PSO converges at the 25th iteration. The IPSO algorithm converges at the 20th iteration. At the same time, the MIPSO algorithm converges at the 12th iteration. The power flow simulation results show that with PSOHIC, the power loss of 16.48 MW is smaller than the current system of 19.10 MW, that is, the power loss is reduced by 0.1613%. The production cost with PSOHIC is IDR 281,860.91/hour, cheaper than MIPSO, IPSO and PSO.

In the pursuit of technologically advanced governance, the Ministry ABC has integrated technology into daily operations, particularly through web applications like an employee administration information system. However, challenges persist in the implementation of online administration, especially in terms of technology adoption among the older generation. This study employs the Technology Acceptance Model (TAM) to investigate the usage of the administrative information system, focusing on System Quality (SQ), Perceived Ease of Use (EU), Perceived Usefulness (PU), and Behavioral Intention (BI). Surveying 147 respondents via questionnaires, the findings reveal that system quality positively influences perceived ease of use and perceived usefulness, while unexpectedly establishing a negative relationship between system quality, perceived ease of use, perceived usefulness, and behavioral intention. These insights hold significance for both theory and practice, reaffirming the crucial roles of perceived ease of use and perceived usefulness in shaping behavioral intentions and augmenting the TAM model.

The use of thin-walled structures as impact energy-absorbing media has been carried out by many researchers. The cylindrical tube shape is very popular and is used in an extensive area. Many ways are done to increase the ability to absorb energy and reduce the maximum reaction force. This study investigates the behavior of single- and multiple-layer thin aluminum tubes. The finite element method is used to model specimens and impactors. One end of the sample is subjected to a fixed support, and the other is subjected to impact at a speed of 50 m/s. The specimens used consisted of one, two, three, and four layers with a fixed total thickness of 4 mm. The results showed that the single layer has the slightest total deformation and the most significant reaction force for relatively the same energy absorption. Using more layers increases the deformation length but decreases the reaction force. This is due to the absence of adhesive between layers, so all layers work together simultaneously. The results of this study assist as a recommendation for the manufacture of high-speed impact energy-absorbing structures.

There is a variation in nickel content produced by PT. Aneka Tambang Tbk Site Pakal with the needs of the processing industry so that the blending method needs to be applied. Blending is the process of mixing two or more materials that have different qualities to get the right mixture. In the blending process, it must meet the specific ore according to the needs of the processing plant. The results of the XRF analysis on the stockpile Sosolat, Bicoli, Maba, Mafia, Sangaji, Roomstock Harmony, Resampling Sangaji were respectively 2.26%, 1.61%, 1.48%, 1.35%, 1.32%, 1.53%, and 1.60%.

Indonesian government has established measurable fishing regulations by Government Regulation 11/2023 to protect and sustain fishery resources. This policy is unsuitable for small fishermen's needs and has resulted in mass demonstrations in South Papua. Data were conducted with the fishermen demonstrators (n=100) by participation observation, in-depth and semi-structured interviews. The results showed fishermen refused the regulated fishing regulations for vessels <30 GT as far as 12 miles, simplify the licensing process, increase the fuel quota and repeal mooring requirements only at the Merauke fishing port. Formulating laws and regulations for fisheries management requires a combination of ecological, economic, and sociocultural principles to sustain fisheries systems. Stakeholder involvement must be implemented into every policy design and decision-making stage by integrating fishermen's perspectives in the fishing business. Integrating fishermen's points of view can be a benchmark for the suitability of fishermen needs and sustainability of fisheries resources in each region.

Wrong posture while working has an impact on productivity. One of them is the operator's work position in the production department at PT. XYZ pays little attention to natural work attitudes and there are activities that have a fairly high ergonomic risk. As a result, complaints such as pain in the legs, shoulders, knees, neck and even the arms occur. At worst, it can lead to long-term sprains and fractures. It is necessary to analyze work posture using the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) methods to determine the level of musculoskeletal hazards and provide improvements to work methods or rearrangement of the work environment. The final score results in the application of REBA and RULA are on the working posture of the both painting sections with scores of 4 and 9, on screen printing on the bottom of the tube scores of 9 and 10, on ring painting results of scores of 10 and 9, on welding results of scores of 7 and 8, and on the installation of seal tape the results of scores 5 and 6 which need to be repaired immediately. Recommendations are given by changing work postures, adding tables and chairs. The operator's attitude and work position are calculated again using the REBA and RULA checksheets. The result is 3 and 3 both painting, 3 and 3 on tube bottom screen printing, 2 and 3 on ring painting, 2 and 3 on welding, 2 and 2 on seal tape installation, which are (acceptable) or acceptable. Keywords: Working Posture Error, REBA, RULA.
