Abstract

Program Pemberdayaan Masyarakat oleh Mahasiswa atau PMM adalah kegiatan pengabdian masyarakat di mana mahasiswa turun langsung ke lapangan untuk mengidentifikasi, memecahkan masalah, dan mengembangkan potensi masyarakat melalui penerapan ilmu pengetahuan dan teknologi. Tujuannya adalah meningkatkan kepedulian mahasiswa dan memberikan solusi konkret bagi mitra masyarakat, serta memberikan pengalaman lapangan yang berharga bagi mahasiswa. Program ini bertujuan untuk memberikan solusi atas permasalahan yang dihadapi oleh mitra sasaran, khususnya dalam sektor ekonomi produktif dan sosial. Mitra utama dalam program ini adalah dua mitra yang berasal dari desa dibawah binaan Politeknik Negeri Lhokseumawe yaitu UMKM VCO COCOK yang bergerak dalam produksi minyak VCO dan kelompok PKK Desa Jambo TImu yang berpotensi mengolah limbah air kelapa menjadi produk bernilai ekonomi dan peningkatan ketrampilan di bidang pembuatan deodorant spray. UMKM VCO COCOK, yang dikelola oleh ibu Zainah Rahmiati, sebelumnya telah mengalami sejumlah kendala dalam proses produksi dan pemasaran. Produksi yang masih dilakukan secara manual menghasilkan rendemen rendah dan kualitas yang kurang stabil, sementara pemasaran yang terbatas hanya mengandalkan metode konvensional menyebabkan penjualan yang stagnan. Di sisi lain, Kelompok PKK Desa Jambo Timu, meskipun memiliki potensi besar dengan sumber daya kelapa yang melimpah, belum dapat mengembangkan kegiatan ekonomi produktif yang dapat meningkatkan kesejahteraan anggotanya. Program ini bertujuan untuk mengatasi masalah tersebut melalui penerapan teknologi modern, khususnya teknologi cold press untuk meningkatkan kualitas dan kuantitas produksi VCO, serta pelatihan pembuatan produk baru berbasis VCO seperti deodorant alami dan nata de coco. Dengan adanya pelatihan dan branding produk, diharapkan dapat meningkatkan jangkauan pasar dan mendongkrak pendapatan mitra sasaran.

Abstract

This study evaluates the performance of Pure Sine Wave (PSW) and Modified Sine Wave (MSW) inverters within small-scale off-grid solar power generation systems. The assessment was conducted utilizing a 160 Wp monocrystalline solar panel, a 10 A solar charge controller (SCC), a 12.8 V–100 Ah lithium iron phosphate (LiFePO₄) battery, along with both 500 W PSW and MSW inverters, across varying panel tilt angles ranging from 45°-165°. The findings indicated that the PSW inverter delivered a more consistent output voltage between 221 and 222 V, exhibiting minimal fluctuation of ±1 V and low harmonic distortion at 2.5%. The MSW inverter produced an output voltage between 222 and 225.5 V, characterized by greater variability and higher harmonic distortion under both light and heavy load conditions. The analysis of the solar photovoltaic (PV) system provides critical insights into the performance differences between the two inverter types. Notably, the results related to tilt angle are not merely supplementary; they serve as indicators of varying irradiance conditions, enabling a more comprehensive evaluation of inverter performance concerning fluctuations in input power levels. Both PSW and MSW inverters achieved an efficiency rating of 85%, ensuring stable and smooth outputs. However, with regard to long-term reliability, the PSW inverter significantly surpasses its counterpart, rendering it a more appropriate choice for permanent solar PV installations. As the results, the PSW inverter is particularly suited for sensitive loads that demand high power quality, while the MSW inverter remains viable for less demanding applications when the cost is considered.

Abstract

The aim of this study is to design and develop a smart panel module specifically for solar power generation, which includes three critical functions: the automatic transfer switch (ATS), the automatic main failure (AMF), and capabilities for remote monitoring and control. The ATS and AMF features employ Haiwell AT12MOT Ethernet PLC control equipment in conjunction with the Haiwell B7H Ethernet IoT cloud HMI, both designed for remote operation through an IoT system and integrated with the Haiwell cloud application. The developed PLC program interacts with HMI software that is created using NB designer. Inputs from the PLC are monitored and managed via the Haiwell cloud application, which connects with the relay designated as input for the Haiwell AT12MOT PLC. The resulting design interfaces with the PLC output located within an electrical panel specifically designed to handle industrial loads. This research results in a smart panel capable of operating in an industrial context with a power capacity of 2,200 VA. It is noteworthy that during automatic operations, load transfers between solar power systems and PLN (the national grid company of Indonesia) do not occur instantaneously; instead, there is a delay of 10 seconds as the system stabilizes back to normal conditions.

Abstract

This study aims to analyze the influence of the Internal Control System, Community Participation, and Transparency on Village Fund Budget Efficiency—both individually and simultaneously—in Sungai Apit District, Siak Regency, Riau Province. A quantitative approach was employed, utilizing primary data collected via questionnaires. The study population comprised 14 villages, with a sample of 42 respondents selected through purposive sampling, including Village Heads, Village Secretaries, and Financial Officers/Treasurers. Data were analyzed using multiple linear regression with the aid of IBM SPSS Statistics. The results indicate that the Internal Control System did not significantly affect Village Fund Budget Efficiency (β = −0.051; t = −0.147; p = 0.884). Similarly, Community Participation did not have a significant effect at the 5% level (β = 0.387; t = 1.829; p = 0.075), although it showed a tendency toward a positive influence at the 10% level. Transparency also showed no significant effect (β = −0.073; t = −0.207; p = 0.837). However, when considered simultaneously, the three variables significantly influenced Village Fund Budget Efficiency (F = 3.891; p = 0.016) and explained 23.5% of the variation in budget efficiency (R² = 0.235). These findings suggest that budget efficiency is more meaningfully influenced by the combination of internal control, community participation, and transparency.
