Abstract

Thermal Spray Aluminum (TSA) coating is widely applied for corrosion protection of offshore steel structures operating in aggressive marine environments. In practical offshore projects, the quality of TSA coating implementation is primarily verified through inspection activities conducted during Procedure Qualification Tests (PQT). In this study, an inspection-based evaluation of TSA coating implementation was performed using documented PQT inspection records obtained from an offshore steel structure, without additional laboratory testing. TSA coating was applied using a twin wire electric arc spray process, and coating quality was assessed based on dry film thickness (DFT) measurements recorded at five inspection points. The measured DFT values ranged from 216 µm to 357 µm, with an average thickness of 284.8 µm. To ensure general applicability, the thickness distribution was interpreted using inspection-derived statistical indicators, including a thickness uniformity index and coefficient of variation. The results indicate a uniform coating build-up and stable application characteristics typical of arc-sprayed aluminum coatings. It is concluded that PQT inspection data provide a practical and reliable basis for evaluating TSA coating implementation and thickness consistency in offshore steel structure applications.

Abstract

An automatic monkey detection and repellent system based on a Convolutional Neural Network (CNN) and a Raspberry Pi was developed to address crop damage caused by monkeys in Sugie Village, Karimun district. The system uses a webcam to detect monkeys within a radius of up to 50 meters and emits gunshot sounds audible up to 200 meters to automatically repel them. Solar panels power the system because the area has access to electricity only at night. The implementation of this device yielded significant results, reducing crop damage from an average of 9 damaged plants per visit to only 3, equivalent to a 66.7% decrease. Additionally, the solar panels provided lighting for the agricultural area, improving security and accessibility at night by 100%. This technology offers an effective and efficient solution compared to manual methods, which require constant monitoring. The project leverages modern innovation relevant to local needs by integrating renewable energy with image-based detection technology. This project has the potential to be replicated in other regions facing similar issues, supporting food security and improving rural communities.

Abstract

Monkey pest attacks pose a serious threat to agricultural productivity, particularly affecting the Tunas Baru Farmers Group. This study aims to implement appropriate technology to mitigate crop damage caused by these pests. The activity was conducted in Rempang Cate Ward from May to September 2025. The implementation method included field observation, system design (hardware and software), on-site installation, as well as monitoring and performance evaluation. The developed device utilizes a Convolutional Neural Network (CNN) with a Raspberry Pi microcontroller and a webcam to detect the presence of monkeys within a radius of up to 35 meters. Upon detection, the system automatically generates a gunshot sound audible up to a radius of 250 meters to repel the pests. Given that the partner's location lacks access to the PLN electricity grid, the device is powered by solar panels as a renewable energy source. The implementation results demonstrate a significant impact, marked by a reduction in crop damage from an average of nine trees to only three trees per attack incident. This reduction contributed to a 67% increase in production yield compared to the pre-installation period. This technology has proven to be a more effective and efficient solution than manual guarding methods and has the potential to be replicated in other areas to support food security and rural welfare.

Abstract

Currently, motorcycles are the maximum extensively used approach of transportation in Indonesia. apart from being a way of transportation and for delivering items, of direction, it has unique settings from motorbikes which might be used for daily purposes via making overall performance upgrades by using modifying the noken axle (camshaft) on motorbikes which are used each day. The characteristic of the camshaft is to manipulate the valve opening, both the consumption and exhaust valves at the time decided with the aid of the four stroke engine cycle. at the changed engine, numerous adjustments have been made to several systems and components to improve the performance of the bike. The cause of this take a look at become to determine the performance of the Honda Absolute revo 110cc combustion engine which incorporates torque, strength and gasoline intake with the aid of comparing the standard camshaft and The changed camshaft which has modified the lift top by using 1mm has changed in the absolute revo 110cc engine, adjustments occur amongst them in torque, energy and greater gasoline intake enter the combustion chamber. The studies was received from a tool which can decide power called Dynotest. Dynotest serves to measure the torque strength of a motorcycle that has been modified by means of camsaft so as to understand better which is the modified camasafth and the usual camsafth on a 110cc revo absolute motorcycle.

Abstract

Wind energy represents one of Indonesia’s most promising renewable energy resources, with a national potential estimated at approximately 60 GW. However, its implementation remains limited due to insufficient site-specific assessments and feasibility studies. This research analyzes the wind energy potential at Galang District Beach, Batam City, and evaluates the technical suitability of the Sky Dancer 500 (TSD 500) wind turbine equipped with inversed-taper blades for small-scale electricity generation. A descriptive quantitative method was employed using secondary wind speed data from NASA (2014–2018) and primary measurements collected continuously for 30 days. Results show that Galang District Beach, Batam City exhibits average wind speeds ranging from 4 to 13.41 m/s, with a maximum recorded speed of 13.41 m/s. Based on technical analysis, low-speed wind characteristics align well with the operational profile of a horizontal-axis wind turbine utilizing inversed-taper blades. Estimations indicate that the TSD 500 turbine can generate 390–500 Wh of electricity per day under the observed wind conditions. These findings demonstrate that the site possesses adequate potential for micro-scale wind power development, and deploying ten units of the TSD 500 turbine could supply daily electrical needs for approximately ten households. The study contributes to the growing body of literature on decentralized renewable energy solutions for remote and coastal communities in Indonesia..

Abstract

This paper presents an experimental analysis of resonance behavior in a mechanical vibrating beam. A cantilever beam made of aluminum was subjected to forced vibrations using a shaker, and the frequency response was measured with an accelerometer. Resonance frequencies for the first three modes were determined and compared with theoretical predictions based on Euler-Bernoulli beam theory. The experimental results showed excellent agreement with theoretical values, with errors less than 1%, validating the approach. This study underscores the importance of understanding resonance in mechanical structures to prevent failures due to excessive vibrations.

Abstract

This study aims to develop an economical, efficient, and precise automatic fabric cutting machine to improve productivity and quality in small to medium-scale textile industries. Traditional manual cutting methods often lead to inconsistent results, lengthy cutting times, and human error, which can hinder production efficiency. The research involves designing the machine, selecting key components, assembling the tool, and testing its performance on various fabric types. Results show that the automatic fabric cutting machine enhances cutting speed by up to 50% with consistent precision, while also reducing fabric waste caused by cutting errors. The study concludes that this machine offers a viable solution for textile industries to improve efficiency and quality at a lower cost compared to commercial machines. Further improvements are suggested to include automated pattern-cutting capabilities and better fabric compatibility.
