Abstract

The photovoltaic thermal (PVT) system is an up-and-coming renewable energy technology that simultaneously produces thermal and electrical energy. The objective of this paper is to improve the electrical efficiency of the photovoltaic thermal system with and without ∇-groove absorber. This study is an experimental investigation under an indoor solar simulator at The National University of Malaysia. The electrical characteristic of the PVT system is characterized by the scheming current (A), voltage (V), power (W) curves. The solar intensity and mass flow rate affected the electrical characteristic. The increase of produced power and electrical efficiency is caused by increasing the solar intensity and mass flow rate. The comparison between ∇-groove absorber and without ∇-groove absorber shows that the use of ∇-absorber can increase electrical efficiency.

Photovoltaic technology is one of renewable energy technology very hopeful, especially photovoltaic thermal system or PVT system. A PVT system solar air collector produces hot air and electricity simultaneously. In this study, indoor and outdoor investigation comparison of PVT system solar air collector has tested at the National University of Malaysia. The indoor and outdoor investigation conducted with variation mass flow rates from 0.01 kg/s to 0.05 kg/s at the solar intensity of 820 W/m2. Indoor and outdoor evaluation is conducted to precisely evaluate the performance improvement theorized by the researcher. The comparison between the indoor and outdoor outcome purposed to confirm each testing and attraction decision. The outdoor investigation outcomes were agreement with indoor results. Indoor investigation outcomes reliably with outdoor investigation outcomes indicated by accuracy results.

Abstract

The integration of photovoltaic technology and solar air collector is named a photovoltaic thermal (PVT) system. PVT system generates electricity as pumping power to fan DC and produces thermal energy together with to cooling PV panel. The experimental with the indoor and outdoor evaluation of PVT solar air collector have been compared at the chosen solar intensity of 820 W/m2. The mass flow rate is range from 0.01 kg/s to 0.05 kg/s. The exergy and efficiency exergy accuracy of PVT solar air collector between indoor and outdoor evaluation are 98.42%, 98.11% respectively. The exergy and exergy efficiency comparison results indicated that the indoor and outdoor investigation is suitable.

Abstract

Operating a computer as a data processor is needed in all fields. One of the fields that must master Information Technology, and Communication (ITC) skills is the field of government, from the central government to the village government. It is crucial to upgrade the capabilities of computers for village officials because, currently, all data is computerized. The purpose of this community service is to help improve the computer/laptop and internet skills of village staff, especially in Perampuan Village, Labuapi District, West Lombok Regency, NTB. The stages in this service are: analyzing service problems; second, preparing service material; third, carrying out service; and fourth, reporting or post-service activities. The results show increased participant ability on computers and the internet. The participants were enthusiastic about the training on making Google Drive, Google Docs, and Google Spreadsheets because this was the first training they had received. Because creating Google Drive, Google Docs, and Google Spreadsheets is necessary for village services, especially in an era when all residents have smartphones, and all data must now be cloud-based. The village head and the training participants hope the Mataram UIN lecturer service team will still be scheduled to carry out a community service program because the village really needs this service. The participants also suggested that they spend more time so that they are more flexible in the teaching and learning process

Abstract

Abstrak Pengadian ini dilaksanakan atas dasar kebutuhan masyarakat di Dompu terhadap kecukupan air untuk irigasi pertanian pada musim kemarau ataupun musim hujan. Permasalahan yang terjadi adalah disaat musim hujan, banjir melanda masyarakat setempat karena penebangan hutan yang berlebihan dan mengakibatkan kerugian petani. Sedangkan, di saat musim kemarau masyarakat kekurangan air untuk pertaniannya. Oleh karena itu pengabdi ini memberikan solusi dengan menerapkan teknologi irigasi tetes bagi petani berbasis energi terbarukan. Pengabdian ini dilaksanakan melalui beberapa tahapan seperti melakukan survey lokasi, diskusi dengan petani, mendesain kegiatan, instalasi produk teknologi irigasi tetes, dan evaluasi terhadap kegiatan. Dari kegiatan ini, instalasi panel surya sebagai energi terbaru yang dikembangkan mampu membantu masyarakat setempat. Berdasarkan evaluasi pengabdi, pengabdian ini perlu dikembangkan dengan mengadakan panel surya yang lebih banyak sehingga cakupan area pertanian yang bisa dijangkau semakin luas. Kesimpulan dari pengabdian ini adalah instalasi energi terbarukan menggunakan panel surya dapat membantu sistem irigasi pertanian masyarakat baik secara teknis ataupun ekonomis. Kata kunci: irigasi; pertanian; energi terbarukan. Abstract This trial is carried out based on the needs of the people in Dompu for sufficient water for agricultural irrigation in the dry season or rainy season. The problem that occurs is during the rainy season, floods hit the local community due to excessive logging and causing losses to farmers. Meanwhile, during the dry season, the community lacks water for agriculture. Therefore, the devotees provide solutions by applying irrigation technology for farmers based on renewable energy. This service is carried out through several stages such as conducting site surveys, discussions with farmers, designing activities, product installations, and evaluating activities. From this activity, the installation of solar panels as the latest developed energy can help the local community. Based on the evaluation of the service, this service needs to be developed by providing more solar panels so that the coverage of the agricultural area that can be reached is wider. This service concludes that the installation of renewable energy using solar panels can help the community's agricultural irrigation system both technically and economically. Keywords: irrigation; agriculture; renewable energy.

Abstract

Statistical data analysis is the process of examining, cleaning, transforming, and modeling data with the aim of discovering useful information, drawing conclusions, and supporting decision-making. This process involves various statistical techniques and methods applied to data to understand, explain, and predict phenomena. Skills like these are greatly needed by students. Therefore, training in the use of the open-source statistical application JASP is necessary to enhance the statistical data analysis capabilities of UIN Mataram students, especially those in their final semester. This community service activity aims to introduce and train the use of JASP as a free and license-free alternative for statistical data analysis, considering the limitations of accessibility and ethical issues surrounding the use of paid software like SPSS in academic environments. The training methodology includes theoretical sessions and practical application of JASP, focusing on multiple linear regression analysis and path analysis. An initial survey showed that only 25% of final-semester students were familiar with open-source applications like JASP. After the training, there was a significant increase in understanding and application of JASP, with 85% of participants showing improved competence. These results demonstrate the importance of training in open-source statistical applications to support student academic research and strengthen academic integrity within the Islamic university environment. This study provides insights into ethical and affordable statistical software alternatives and highlights the importance of analytical skills in higher education.
