Abstract

The mental well-being of Indonesian university students is currently facing complex pressures, ranging from heavy academic demands to economic instability and the psychological impacts of social media interactions. Unfortunately, the availability of professional psychologists is not commensurate with the population in need, creating a significant service gap. This study aims to design "BUBU," a web-based artificial intelligence agent positioned as a first-line defense for psychosocial support. The system is developed using a Human-Centered Design approach, integrating multimodal inputs (text, voice, and visuals) to detect user emotions in real-time. BUBU is trained using a Large Language Model (LLM) with prompt engineering techniques that adopt student vernacular (slang/code-mixing) and Active Listening protocols. Test results show that the system is capable of providing contextual emotional validation, adjusting response tones based on facial expressions, and possesses a fail-safe mechanism to detect suicide risks and provide appropriate referrals. This prototype offers potential as an effective mental health triage tool in campus environments.

Abstract

Raindrops hitting the roof material and the falling rainwater exerting pressure on the roof can be utilized as a power source with piezoelectrics as a converter of mechanical energy into electrical energy. The purpose of this research is to find the right roof material to produce maximum electrical power and efficiency in harvesting the energy of falling rainwater. This research method is carried out by comparing three types of roof materials placed on top of the piezoelectric. The falling rainwater will press the roof material and piezoelectric, thus producing electricity in the form of voltage and current measured with a multitester. The measurement data is processed into electrical power and efficiency. The results of the study found that the type of roof material affects the performance of the piezoelectric as an energy converter.

Abstract

This study discusses the design of an automatic solar tracker integrated with a solar-powered plant irrigation system. The main objective is to optimize solar energy utilization while reviewing previous research on solar tracking and automatic irrigation technologies to identify the most efficient and sustainable approach. The literature review covers sensor-based tracking using LDRs, HSV image recognition methods, and microcontroller control such as Arduino. Based on the review and implementation, the system was designed to automatically adjust the solar panel’s position according to the sun’s movement, while irrigation is controlled by soil moisture sensors. Experimental results show that the integrated system improves solar energy absorption and water-use efficiency compared to conventional methods. Therefore, this integration provides an effective, energy-efficient, and eco-friendly solution suitable for small-scale agricultural applications.

Abstract

The multi-plate pipe punching process is a crucial manufacturing technology in modern industry, especially in the manufacture of high-precision perforated pipe components. This study aims to examine the development of an optimal punch eye design to improve efficiency and product quality in the multi-plate pipe punching process. The method applied in this research is descriptive literature analysis by reviewing various relevant reference sources on punch design, materials, and punching process parameters. The results show that the optimal punch design must consider geometric factors, material selection, cooling systems, and wear analysis. Material innovations such as tool steel with high alloy steel and special coatings have been proven to increase service life. Finite Element Analysis (FEA) simulation is an effective tool for design optimization prior to actual implementation. This study provides punch eye design recommendations that can be practically applied in the manufacturing industry to increase productivity and reduce production costs.

Abstract

Reliance on PLN electricity for street lighting (PJU) and security CCTV requires high operational costs and is vulnerable to outages. Solar panels (PV) are a sustainable, efficient, and environmentally friendly renewable energy solution to improve security while reducing carbon emissions. This study aims to analyze the technical efficiency and economic feasibility of an integrated solar panel system to power street lighting and security CCTV in a neighborhood. The methods used were literature review and system calculation analysis (mathematical simulation). The calculations involved determining the daily power requirements of the street lighting and CCTV, the required solar panel capacity (Watt-peak), and battery capacity. Panel power efficiency was investigated based on irradiation intensity and tilt angle. The analysis results indicate that the PV system is highly effective and has potential. System efficiency can be significantly increased (15-20%) by implementing automatic/IoT controls. Although the initial installation costs tend to be higher, in the long term, this system is significantly more economical than conventional systems, providing sustainability and energy independence benefits

Abstract

The growing demand for environmentally friendly cooling technologies has encouraged the use of thermoelectric systems based on the Peltier effect as an alternative to conventional vapor-compression systems that rely on harmful refrigerants. This research focuses on designing a portable cooling device powered by solar-generated electricity to create an efficient and sustainable refrigeration solution. The system integrates solar panels, a battery, a TEC module, a heatsink, a coldsink, and cooling fans to ensure effective heat dissipation. Performance evaluation was conducted through three experimental tests by calculating the Coefficient of Performance (COP) and analyzing convective heat transfer using Reynolds number, friction factor, Nusselt number, and heat flux. The results show that solar intensity plays a key role in determining the electrical power supplied to the thermoelectric module, thus influencing its cooling performance. COP values varied across the trials, with the highest average value of 0.167944 recorded in the third test. Although its efficiency remains lower than that of vapor-compression systems, the prototype demonstrates that a solar-powered thermoelectric cooler can serve as an energy-efficient, refrigerant-free, and environmentally friendly portable cooling solution.

Abstract

Peltier technology uses the thermoelectric effect to transfer heat from one part of the module to another, allowing it to function as a cooler or heater without moving mechanical components. Despite its advantages in terms of reliability and environmental compatibility, Peltier modules still lack energy efficiency compared to traditional cooling systems. Previous research has focused on improving performance through innovations in semiconductor materials, thermal system design, and optimization techniques. In applications to small machines, key challenges include managing the heat on the hot side, incorporating compact designs, and maintaining stable operating temperatures. However, research findings indicate that with appropriate design and material advancements, Peltier modules have the potential to provide efficient and sustainable cooling solutions for low-power machines and portable biomedical devices.

Abstract

Ergonomic analysis of riding posture on a chopper frame based on rider anthropometry is crucial to ensure comfort and safety during riding. This study examines the suitability of the chopper frame's dimensions with the rider's body size using representative anthropometric data. Through measurement and comparison methods, the research identifies geometric mismatches in seating position and control placement that can cause discomfort, muscle fatigue, and long-term injury risks. The analysis results indicate that seat dimensions and frame height need adjustment to match the rider’s anthropometric percentiles to optimize an ergonomic riding posture. This research offers ergonomic design recommendations for chopper frames to enhance comfort and reduce injury risks, using anthropometry as a design reference for two-wheeled vehicles. The findings are expected to guide the development of safer and more comfortable chopper motorcycles, supporting national ergonomic standards
