The purpose of this study is to analyze the deformation, equivalent elastic strain, and safety factor of a bracket bracket made from two different materials by using the Finite Element Method, specifically aluminum alloy 6061 T6 and cast iron EN GJL 100. The result of this study is that the Aluminum Alloy 6061T6 material has a deformation of 3.57E-04 whereas the Cast iron EN GJL 100 material is 2.75E-04. In the elastic strain equivalent test, the Aluminium alloy 6061 T6 material is 3.00-E07 and in the Cast Iron EN G JL 100 materials is 2.32E-07. In the safety factor test, Cast Iron En G J L 100 material was better than 1.8617 compared to the Alumium Alloys 60 61 T6 materials are 1.5125. This shows that Cast Iron E GJ L 100 materials are better in deformations, eqeuivalent elastic stations, and safety factors in this case.

With 64.97% of its territory consisting of sea, Indonesia is one of the world's largest maritime nations and produces approximately 8.02 million tons of fish annually. Traditional fishing vessels play a crucial role in supporting livelihoods, yet their design is often based on hereditary methods rather than hydrodynamic optimization. This study uses catamaran hull forms as a design reference to analyze the total resistance and wave patterns of purse seine vessels with photovoltaic-powered systems. Computational methods are employed to predict vessel performance efficiently. The resistance analysis applies the Slender Body approach and Savitsky's mathematical model, supported by comparative studies for validation. Particular attention is given to the influence of chine configurations on resistance characteristics and wave formation. Results indicate that the addition of chines increases the Froude number and contributes to reducing total resistance. Among the variations, single chine geometry demonstrates the lowest resistance, making it the most efficient configuration for catamaran fishing vessels. While chine modifications affect the wave pattern, the hull maintains a relatively clean wake distribution. These findings highlight the potential for improving vessel design through careful chine geometry optimization combined with computational modeling. The study underscores the importance of modern hydrodynamic analysis in advancing traditional fishing vessels toward higher efficiency and sustainability. Future research is recommended to incorporate more advanced computational approaches, such as Computational Fluid Dynamics (CFD), examine water-hull interactions and enhance vessel performance under operational conditions.

The “Dewi Sri” Farmers Group is located in Terwidi Hamlet in Plalangan Village, Gunungpati, Semarang City, where part of the population raises various livestock, namely cows, goats and poultry. The problem that occurs is the accumulation of cow dung which causes environmental pollution. This service activity aims to overcome the buildup of livestock waste, especially cow manure by using it as organic fertilizer and then packaging it with an attractive design so that it has a high selling value. The methods used are preparation, socialization, and mentoring. The results obtained from this activity, the preparation/coordination stage with the head of KT Dewi Sri, the socialization stage in the form of an explanation of the innovative packaging design, and the mentoring stage in the form of the issuance of a Packaging Design Copyright by the Directorate General of Intellectual Property.

Education is important for every human because we can think and have a lot of knowledge for life. Children with special needs for mental retardation have problems or problems during the learning process, one of them is thematically. The Research and Development (R&D) research method is carried out by studying research related to the product, developing a product based on these findings, testing it in the field in a setting, and revising it to correct deficiencies found at the proposed testing stage. The development model used in this research is the Analyze, Design, Develop, Implement, and Evaluation (ADDIE) model. Analysis of the needs of mentally retarded students found the competencies need to be improved are the ability to read, write and count or commonly called calistung. This model will develop a learning media. The learning media that will be developed are in the form of modules intended for students with mental retardation in grade 2 elementary school (SD). The module was then developed into a learning module that is integrated with digital media. This development resulted in a product in the form of a printed module of the hypercontent type of digitally integrated thematic subject for grade 2 students of the Elementary School with Special Requirements. This module can help the teaching and learning process that is suitable to be applied to mentally retarded children.

Pakan ternak merupakan faktor terbesar yang mempengaruhi produktivitas ternak. Dalam hal ini, mitra masih mengalami kendala dalam proses pengeringan pelet sebagai pakan ternak. Hal yang masih dilakukan dengan melakukan proses pengeringan pakan ternak terdahulu yaitu masih dilakukan secara konvensional dengan dijemur dibawah terik sinar matahari, sehingga tidak efektif dalam mengeringkan pakan ternak. Oleh karena itu perlu penerapan teknologi pengeringan dari hasil pengolahan pakan ternak menggunakan mesin rotary dryer. Mesin pengering dengan rotary dryer ini, pakan ternak dapat dikeringkan menggunakan drum pengering yang terbuat dari baja tahan karat dan dengan sistem kontrol komponen PLC. Hasil pengeringan menggunakan mesin pengering rotary dryer dihasilkan dalam bentuk serbuk atau butiran. Penerapan teknologi mesin rotary dryer ini dirancang untuk mencapai beberapa tujuan, termasuk meningkatkan efisiensi pengeringan pakan ternak dan meningkatkan kualitas dan produksi pakan ternak. Penerapan teknologi mesin pengering rotary dryer ini diharapkan dapat meningkatkan kualitas dan produksi pakan ternak di CV SIBAD Engineering Semarang.

Due to bumps or holes in the road, certain regions' road surface is still unsuitable for riding at high speeds. Many motorcycles used stabilizer steering dampers to reduce weave and wobble. Bracket is a structure that holds the stabilizer steering dampers to the motorcycle steering. Bracket plays a significant role in maintaining the stabilizer steering dampers as well as stopping any vibration due to the dynamic conditions. This paper presents Finite Element Analysis of a bracket, which is analyzed material aluminum 6061 and aluminum alloy cast. In this study, we have explored using Static Analysis to calculate the internal force, displacement, and stress of structural brackets. Hence in this study, we have performed Modal Analysis to determine the natural frequencies of the bracket for safety. And also, we have performed Transient Analysis to study the behavior of structure brackets over time in response to time-varying loads and vibrations in dynamic conditions.
