Abstract

Roof tiles play a vital role in the construction industry hagoslot by providing protection from the sun's heat and rain. The quality of roof tiles largely depends on the materials used and the manufacturing process, as these factors significantly affect the tiles' mechanical properties. Kangkung pagar (Ipomoea carnea) is one type of alternative natural fiber material that can be utilized in the creation of composite materials. This study aims to explore the potential of Ipomoea carnea powder as an alternative material for producing polymer roof tiles, as well as to examine how variations in the composition of powder and sand influence the mechanical properties of these tiles. The method for producing roof tiles is based on powder metallurgy. The composition of the powder and sand used varies in the following ratios: 10% powder to 50% sand, 20% powder to 40% sand, and 30% powder to 30% sand. Additionally, a fixed composition of 30% polyester resin and 10% asphalt is used. The initial process involves mixing the materials according to these predetermined ratios. The resulting mixture is then molded and compacted under a pressure of 200 kg/cm². Characterization of the mechanical properties includes proximate analysis, calculation of porosity and density, flexural strength testing, and hardness testing.The study's results indicated that the properties of polymer roof tiles are significantly influenced by the composition of the powder and sand used during their manufacture. The findings revealed a porosity value of 0.209%, a density of 0.994%, a flexural strength of 2.270 MPa, and an optimum hardness of 19.1 BHN. The addition of 10% powder increased the hardness value by only 0.4% while decreasing the flexural strength by 0.5%. Overall, the use of Ipomoea Carnea powder was not effective in enhancing the mechanical properties of the polymer roof tiles, as both the flexural strength and hardness values remained below those of commercially available polymer roof tiles.

Abstract

Bamboo is a natural material that is widely found in South Banten. Using bamboo as an alternative material for manufacturing brake pads is interesting to research. Bamboo resistance to attacks of organisms is so low that it is necessary to give initial treatment. Preservation of bamboo sticks is done by soaking them in seawater. This immersion is determined for 15 and 30 days. The comparison of the composite constituent composition is 30% bamboo fiber, 28% bamboo particles, 2% zinc, and 40% epoxy resin. Compaction pressure is carried out by 400 kg/cm2 for 10 minutes. The sintering process is carried out at a temperature of 150 °C for 60 minutes. From this research, it is known that the immersion of bamboo stems in seawater tends to decrease the hardness and the wear rate of composites.

Abstract

Damage to sparger headers, such as material thinning and leakage, can reduce system reliability and disrupt industrial operations. Repair welding using Gas Tungsten Arc Welding (GTAW) is commonly applied; however, its quality must be verified to ensure safe reuse. This study evaluates the quality of GTAW-based repair welding on a corrosion-damaged sparger header using Non-Destructive Testing (NDT), namely Liquid Penetrant Testing (LPT) for surface defect detection and leak testing for sealing performance under pressurized conditions. Unlike previous studies that focus on newly fabricated welds under laboratory conditions, this study evaluates repair welding performance on an actual industrial component affected by corrosion-induced wall thinning. The combination of surface inspection using LPT and functional validation through leak testing under real operating conditions provides a more comprehensive assessment of repair quality. Results show no surface indications in LPT and no leakage during testing at 1.2 kg/cm² for 37 minutes. These findings indicate that the repaired weld meets acceptance criteria and is suitable for reuse. The results provide a reliable basis for assessing repair welding quality in industrial components.

Abstract

This research was conducted because the problems faced by students regarding vernier calipers in schools have become very complex. The minimal use of technology-based learning media, the lack of infrastructure, and the lack of student interest in learning vernier calipers are things that need to be considered. Therefore, teachers must combine digital learning media and relevant materials that can be used for learning development. The purpose of this study was to determine the development process, the level of validity, and the level of practicality of Weebly-based digital learning media with vernier caliper learning materials. The research method used was Research and Development (R&D) with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The subjects of this study were students of Automotive Engineering 2, SMKN 2 Tangerang and productive teachers of Automotive Engineering. The results obtained from this study fall into the "very valid" category. Linguists gave a score of 43 with a percentage of 86%, material experts gave a score of 47 with a percentage of 94% and media experts gave a score of 46 with a percentage of 92%. Furthermore, the results obtained from the responses of teachers and students fell into the "very practical" category with a percentage of 95% with a score of 285. Thus, it can be concluded that the learning media developed is valid and practical for use in the learning process.

Abstract

The Material testing is an essential stage in ensuring the quality and safety of engineering components, particularly in welded joints. One of the most widely used methods is Non-Destructive Testing (NDT), which is a testing technique that does not damage the material. This study aims to examine the Liquid Penetrant Test (PT) method as one of the NDT techniques used to detect surface defects in materials. The method employed in this study is a literature review based on various scientific references, including ASME and AWS standards. The study covers the working principles, inspection procedures, dwell time parameters, and acceptance criteria of the penetrant testing method. The results indicate that the PT method operates based on the capillary action phenomenon, where the penetrant liquid is able to enter small cracks or discontinuities on the material surface. The testing process consists of several main stages, including surface cleaning, penetrant application, penetration time (dwell time), excess penetrant removal, developer application, and visual inspection. Furthermore, the evaluation of test results is conducted based on ASME and AWS standards, which classify indications into linear and rounded indications. Linear indications are generally not acceptable due to their association with critical defects, while rounded indications may be acceptable within certain limits. Therefore, the Liquid Penetrant Test method is an effective and practical technique for detecting surface defects and supporting the improvement of structural quality and safety.

Abstract

The Special Job Exchange, or Bursa Kerja Khusus (BKK), is a school-based career service unit that supports graduate placement and strengthens the link between vocational education and industry needs. However, BKK services at SMKN 2 Tangerang were still managed conventionally through manual alumni records, simple spreadsheets, and informal job vacancy dissemination. This study developed a web-based BKK information system integrated with the Profile Matching method to support alumni data management, job vacancy distribution, and competency-based job recommendation. The study used a Research and Development approach with the Waterfall model, including requirement analysis, system design, implementation, testing, and maintenance. The system was developed using PHP and MySQL. The results showed that the system supported centralized alumni data management, real-time vacancy information distribution, and structured job recommendation ranking. Black Box Testing indicated that all main features functioned according to user requirements, while algorithmic verification confirmed that the Profile Matching calculation was consistent with manual computation. User Acceptance Testing produced an average score of 91%, indicating that the system was feasible for supporting digital BKK services.
