Abstract

Utilization of renewable energy, such as Solar Power Plants (PLTS), is becoming increasingly important in efforts to reduce dependence on fossil energy and reduce greenhouse gas emissions. The 50WP PLTS Trainer is designed to provide a practical and in-depth understanding of the installation and operation of small capacity PLTS. This trainer has a capacity of 50 watt peak (WP) and is specifically designed to turn on the blower on conventional stoves. The main components of this trainer include solar panels as the main energy source, a charging controller to regulate the current and voltage from the solar panels to the energy storage battery, and an inverter to convert direct current (DC) to alternating current (AC) needed to operate stove blower. Through the use of this trainer, users can learn the process of installing solar panels, designing battery charging systems, and setting up inverters to ensure compatibility and efficiency in operating conventional electrical devices. Thus, the 50WP PLTS trainer is an effective tool in supporting education and development of renewable energy technology in various environments. Keywords: Solar Power Plant (PLTS), PLTS Trainer, conventional stove, blower, solar energy.

Abstract

Pembangunan karakter artinya membangun yang mempunyai sifat memperbaiki dan membina. Sedangkan karakter adalah watak, akhlak atau budi pekerti yang membedakan seseorang dari yang lain.pengertian pembangunan karakter (character building) adalah suatu proses atau usaha yang dilakukan untuk memperbaiki sifat atau watak. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kualitatif, artinya data yang dikumpulkan bukan berupa angka-angka bilangan melainkan data tersebut berupa naskah wawancara, catatan lapangan dan dokumentasi. Hasil penelitian menunjukkan bahwa, 1) Karakter para siswa di SDIT Annajah cukup baik, dapat dilihat dari sifat sopan santun dan tekun dalam belajar terutama dalam menghafal Al Qur’an, 2) Kegiatan tahfidz Al Qur’an di SDIT Annajah yaitu sebelum menambah hafalan siswa diharuskan muraja’ah hafalan terlebih dahulu, dan setiap hari siswa di wajibkan menyetor hafalan minimal 1-5 ayat. Diharapkan siswa setelah lulus dari SDIT Annajah mampu menghafal minimal 2 juz Al Qur’an juz 29 dan 30, 3) Setelah mengikuti program tahfidz Al Qur’an peserta didik di SDIT Annajah menjadi lebih antusias dalam hal-hal yang positif, dan juga para siswa memiliki sifat yang tanggung jawab atas apa yang telah dia miliki dan dia lakukan. Serta siswa menjadi lebih patuh terhadap nasehat orang tua, dan menjadi lebih antusias belajar bersama dengan teman-teman sesusianya.

Abstract

Latar Belakang: Diabetes Melitus adalah penyakit gangguan metabolik yang disebabkan oleh gagalnya organ pankreas dalam memproduksi hormon insulin secara memadai. Berdasarkan data dari Biddokkes Polda Aceh tentang Diabetes Melitus dapat diketahui pada tahun 2020 terdapat 62 kasus personil menderita Diabetes Melitus, Tahun 2021 menurun menjadi 54 kasus Diabetes Melitus akan tetapi pada tahun 2022 kasus Diabetes mellitus pada personil di Polda Aceh meningkat kenjadi 56 kasus. Tujuan Penelitian: Mengetahui korelasi antara umur dan faktor genetic dengan kejadian diabetes mellitus pada personil Polda Aceh di rawat jalan bidokkes Polda Aceh tahun 2023. Metode Penelitian: Penelitian yang dilakukan menggunakan rancangan penelitian crossectional dengan jumlah sampel 97 orang. Pengumpulan data dilaksanakan pada tanggal 02 Oktober 2023 s.d 21 Oktober 2023. Analisa data penelitian menggunakan analisa univariate dan bivariate dengan menggunakan uji Chi-Square dengan nilai CI (Confident Interval) 95%. Hasil Penelitian: hasil penelitian ini menunjukkan bahwa hubungan Kejadian Diabetes melitus dengan usia (p=0.000), faktor genetik (p = 0.000). Kesimpulan: Ada hubungan antara usia dan faktor genetik dengan kejadian Diabetes Melitus pada personil Polda Aceh di rawat jalan Bidokkes Polda Aceh Tahun 2023. Diharapkan dapat meningkatkan kepatuhan dan memperbaiki gaya hidup sehingga tercapai tujuan dari pengobatan serta meningkatkan pengetahuan tentang diabetes mellitus sehingga lebih mengenal tentang penyakit diabetes mellitusKata Kunci : Kejadian Diabetes mellitus, Usia, Faktor GenetikBackground: Diabetes mellitus is a metabolic disorder caused by the failure of the pancreas to adequately produce the hormone insulin. Based on data from Biddokkes Polda Aceh regarding Diabetes Mellitus, it can be seen that in 2020 there were 62 cases of personnel suffering from Diabetes Mellitus, in 2021 it decreased to 54 cases of Diabetes Mellitus but in 2022 cases of Diabetes mellitus in personnel at Polda Aceh increased to 56 cases. Research Objective: Knowing the correlation between age and genetic factors with the incidence of diabetes mellitus in Polda Aceh personnel in the outpatient bidokkes Polda Aceh in 2023. Research Methods: The research conducted used a crossectional research design with a total sample of 97 people. Data collection was carried out on October 02, 2023 to October 21, 2023. Analysis of research data using univariate and bivariate analysis using the Chi-Square test with a 95% CI (Confident Interval) value. Research Results: the results of this study indicate that the association of diabetes mellitus incidence with age (p = 0.000), genetic factors (p = 0.000). Conclusion: There is a relationship between age and genetic factors with the incidence of Diabetes Mellitus in Aceh Police personnel in the outpatient Bidokkes Polda Aceh Year 2023. It is hoped that it can increase compliance and improve lifestyle so as to achieve the goals of treatment and increase knowledge about diabetes mellitus so that it is more familiar with diabetes mellitus.Keywords: Diabetes mellitus incidence, age, genetic factors

Abstract

This study aims to conduct a comprehensive statistical evaluation of photovoltaic inverter performance under various solar irradiance conditions to identify operational characteristics and develop predictive performance models. The research methodology employs a quantitative approach with experimental design through primary data collection over 12 months using an integrated data acquisition system with pyranometer irradiance sensors, temperature sensors, and power analyzers on a 10 kW string inverter system. Data were categorized into five irradiance groups and analyzed using descriptive statistics, correlation analysis, polynomial regression, and ANOVA with SPSS and MATLAB software. Results show the highest average efficiency in the high irradiance category (96.9%) with the lowest coefficient of variation in moderate irradiance (2.19%). Strong positive correlation between irradiance and inverter efficiency (r = 0.762) and cubic regression predictive model demonstrate high accuracy (R² = 0.912, RMSE 1.89%). Variance analysis proves significant differences between irradiance categories (F = 1,234.56, p < 0.001) with 78.5% effect size. Temporal patterns show systematic seasonal variation with peak efficiency in May (96.2%) and annual-daily periodicity correlating with natural irradiance cycles. The research confirms the importance of statistical characterization for photovoltaic inverter performance optimization and development of adaptive operational strategies based on irradiance conditions. Keywords: photovoltaic inverter, statistical analysis, solar irradiance, energy efficiency, predictive model
