Abstract

One of the main challenges in PV system deployment is the increase in panel operating temperature, which leads to a reduction in energy conversion efficiency, particularly in tropical regions with high solar irradiance. Potential solution to mitigate this issue is the partially submerged photovoltaic (PSPV) system. This study aims to analyze the influence of convective heat transfer coefficients on the surface of a PSPV system on the operating temperature of photovoltaic panels using a numerical modeling approach. The research methodology involves the development of an energy balance model that accounts for the contributions of solar radiation, convective heat transfer, and thermal radiation. The panel area is divided into two equal sections with a 50:50 ratio, consisting of a submerged portion and an air-exposed portion. The convective heat transfer coefficients for the submerged section are set to 100 W/m²K for both the upper and lower surfaces. For the air-exposed section, the upper surface convective heat transfer coefficient is varied between 10 and 70 W/m²K, while the lower surface coefficient is maintained at 10 W/m²K. Simulation results indicate that the presence of water as a cooling medium significantly reduces the panel operating temperature to approximately 31 °C, compared to a fully air-exposed panel configuration, which reaches an operating temperature up to around 55 °C.

Abstract

Currently, there are individuals around us living with disabilities caused by accidents or other factors. People with disabilities generally require assistance from others, particularly for mobility or moving from one place to another. Although manual wheelchairs can provide a solution for mobility, they remain challenging to operate using hand power alone and often require external help for movement. To facilitate mobility for individuals with disabilities, especially wheelchair users, an electric drive system in the form of an electric motor is proposed as a solution. The development of a motorized electric wheelchair aims to enhance the mobility of individuals with physical disabilities. Members of the Indonesian Association of Persons with Disabilities (PPID) were selected as community service partners for this initiative. It is hoped that, in addition to supporting mobility, the electric wheelchair can also serve as a body support system, enabling users to continue engaging in productive activities while seated.  The implementation of this program began with interviews conducted with persons with disabilities and related partners to understand their needs, followed by the design, fabrication, and subsequent socialization and training on the use of the electric wheelchair for the target beneficiaries. The outcome of this effort is an electric wheelchair equipped with joystick controls. The wheelchair employs a rear-wheel drive system powered by two motors, each attached to a rear wheel, and a chain transmission system. Along with delivering the electric wheelchair to the PPID, this initiative aims to serve as a practical application of mechanical engineering knowledge, directly benefiting the community..

Abstract

Vocational high school (SMK) students represent a level of vocational secondary education expected to fulfill the demand for technical labor at specific levels within the industry. However, current SMK graduates face challenges due to intense competition in securing employment. This community service initiative aims to enhance the skills of SMK students by focusing on the utilization of Information and Communication Technology (ICT) in the preparation of post-graduation documents. A case study was conducted at a private vocational high school (SMKS) in and state vocational high school (SMKN) in Tanah Bumbu Regency as an effort to prepare students to face the challenges of Industry 4.0. Through outreach activities, this initiative introduced the concept of community service and the benefits of ICT in document preparation. The methods employed aimed to achieve outcomes such as improving students' skills, applying ICT in preparing supporting documents for job applications, and enhancing students' competitiveness in the labor market. The results of the activities carried out showed an increase in participants' knowledge of curriculum vitae and job application letters. Survey results also indicated that the seminar was highly beneficial for participants in this community service activity through technical outreach.

Abstract

Abstrak      Pengelolaan sampah organik di Bank Sampah Wonorejo Prona 3 Balikpapan menghadapi kendala dalam efisiensi dan nilai tambah. Kegiatan pengabdian masyarakat ini bertujuan untuk memperkenalkan teknologi komposting guna mempercepat proses penguraian sampah organik dan meningkatkan nilai ekonominya. Metode yang digunakan meliputi penyuluhan, pelatihan, demonstrasi alat komposter sederhana, serta pendampingan langsung dalam pembuatan kompos. Pada akhir kegiatan menunjukkan peningkatan pemahaman pengelola dan masyarakat mengenai teknik pengomposan yang efektif dengan penggunaan digester aerobik, teknik penyusunan berlapis dan penghalusan.  Dampak yang diperoleh adalah masyarakat mampu pengolahan sampah organik dengan waktu lebih singkat, mengurangi bau yang tidak sedap selama proses komposting, memproduksi pupuk padat dan cair bernilai ekonomi. Kegiatan berpotensi  pengembangan skala produksi dan kolaborasi dengan pemangku kepentingan dalam keberlanjutan program. Kata kunci: aerobik; bank sampah; komposting; kota balikpapan; sampah organik. Abstract      The management of organic waste at the Wonorejo Prona 3 Waste Bank in Balikpapan faces challenges related to efficiency and value addition. This community service activity aimed to introduce composting technology to accelerate the decomposition process of organic waste and enhance its economic value. The methods employed included counseling, training, demonstration of simple composter devices, and direct assistance in compost production. The results indicated an improvement in the understanding of waste bank managers and the local community regarding effective composting techniques using aerobic digesters, layered arrangement methods, and size reduction. The outcomes achieved include the community’s ability to process organic waste in a shorter time, reduced unpleasant odors during the composting process, and the production of economically valuable solid and liquid fertilizers. This activity holds potential for scaling up production and fostering collaboration with stakeholders to ensure the sustainability of the program. Keywords: aerobic; garbage bank community; composting; balikpapan city; biodegradable waste.
