Abstract

Conventional motorcycle batteries, including wet and maintenance-free types, suffer from limited lifespan, sulfation issues, and high maintenance requirements. This study proposes a LiFePO4 battery pack as a superior alternative, integrating a real-time monitoring system for enhanced performance tracking. Compared to conventional batteries, the developed system offers longer cycle life, improved thermal stability, and reduced maintenance. The battery pack consists of LiFePO4 cells (3.2V 6Ah) arranged in a 4-series 1-parallel configuration, delivering a 12V 6Ah output while maintaining compatibility with standard motorcycle battery dimensions. Experimental testing validates the system’s ability to monitor current, voltage, and temperature parameters effectively. The integration of a data logging system further ensures long-term reliability and optimization of battery performance. This research contributes to advancing motorcycle battery technology by enhancing durability, safety, and real-time performance monitoring.

Abstract

Perdagangan internasional diartikan sebagai sejumlah transaksi perdagangan/jual beli diantara pembeli dan penjual pada suatu pasar, demi mencapai keuntungan yang maksimal bagi kedua belah pihak yang bertujuan untuk meningkatkan Gross Domestic Product (GDP). Perdagangan tersebut terjadi karena tidak ada negara yang mampu memenuhi kebutuhannya sendiri. Pengabdian kepada Masyarakat (PkM) ini pelaksanaannya bekerja sama dengan Pusat Pendidikan Export dan Jasa Perdagangan Kementerian Perdagangan Republik Indonesia. Dengan melakukan pelatihan bisnis online ekspor peserta dalam hal ini dosen dan mahasiswa IBI Kosgoro 1957 memiliki tambahan pengetahuan terkait bagaimana memulai ekspor yang dapat dilakukan secara perorangan.

Abstract

Studi ini menganalisis pemasangan Sistem PLTS atap pada Gedung IsDB Integrated Laboratory for Engineering Biotechnology Fakultas Teknik Universitas Jember. Gedung tersebut memiliki luas bangunan 4.888 m2 dengan pemanfaatan ruangan sebesar 64%. Listrik Gedung ini dipasok dari PLN sebagai pelanggan kategori LS-3 dengan daya terpasang 690.000 VA dan biaya pembayaran Rp. 2.032,-/kWh. Tagihan listrik gedung tersebut mencapai Rp. 849.611.700. Data beban listrik dicatat secara otomatis menggunakan sistem Automatic Meter Reading (AMR), dengan profil konsumsi tertinggi pada pukul 12.00 WIB sebesar 51,8 kWh dan terendah pada pukul 6.00 WIB sebesar 27,5 kWh. Desain PLTS atap gedung ini menggunakan software Helioscope dengan kapasitas 38.2 kWp dan produksi tahunan sebesar 46,12 MWh. Dalam Permen ESDM No. 21 tahun 2021, energi PLTS yang dapat dijual mencapai 100% dari hasil produksi. Penggunaan listrik yang belum maksimal dan tagihan listrik di bawah rekening minimum memungkinkan energi berlebih dapat dijual ke PLN dengan perkiraan pendapatan Rp93.310.066 per tahun. Investasi total pemasangan PLTS atap gedung ini adalah Rp. 544.236.000. Hasil analisis menunjukkan parameter investasi yang layak, dengan Net Present Value (NPV) positif sebesar Rp. 534.162.123, indeks profitabilitas (Profitability Index) sebesar 1,98, dan Payback Period (PBP) sebesar 8,5 tahun. Hasil tersebut menunjukkan nilai yang lebih kecil dari umur investasi 25 tahun yang direncanakan.

Abstract

The Application of Entrepreneurial Concept Development Model For Student in Elementary School Number 11 Lenteng Agung, South Jakarta. The program objection embeded the entrepreneurial concept among elementary school students.The nature of the activity is the pioneering program.

Abstract

The company's financial performance reflects its work plan achievements and can indicate its overall health.  This study estimates operating costs, operating income, and profitability with the FDR financing to deposit ratio as a mediating variable that indirectly or directly affects profitability proxied by return on assets ROA in BPRS for the 2015-2023 period.  This research is a confirmatory study with a quantitative approach. The data in this study are secondary data obtained from BPRS in the form of annual reports, which are taken quarterly and collected through the official website. Based on the study's results, the path coefficient is partially positive, with a value of 0.72 and a p-value of 0.01 > 0.05. BOPO has a positive and significant effect on ROA, with an influence of 67%. BOPO has a positive and considerable influence on FDR, with an impact of 89%. FDR has a positive and significant effect on Return on Assets ROA with an impact of 35%. Simultaneously, BOPO and FDR affect ROA with an R-squared of 0.669, indicating that the contribution of the influence of BOPO (X) variables and FDR Financing to Deposit Ratio (Z) on Profitability (Return on Assets) is 66.9% and other variables outside the research model and errors influence the remaining 33.1%. The Financing to Deposit Ratio of 0.117 with a P-value of 0.232 greater than 0.05 shows that the Financing to Deposit Ratio cannot mediate the relationship between BOPO and Return on Asset ROA. Implications for Future Research. This study highlights the mediating role of the Financing to Deposit Ratio (FDR) in linking financial performance with BPR profitability. Future research could extend this framework by incorporating additional mediating or moderating variables, such as credit risk, liquidity risk, or governance practices, to capture a more holistic view of profitability drivers. For practitioners, the findings underscore that profitability in BPR is not solely determined by financial performance indicators such as ROA or BOPO, but is also significantly influenced by the efficiency of channeling deposits into financing activities, as captured by FDR.
