Abstract

Sistem pelaporan dan manajemen keuangan sangat penting untuk bisnis apa pun, tidak peduli seberapa besar atau kecilnya. Mengumpulkan bukti transaksi untuk mencatat transaksi, menyiapkan buku besar untuk setiap akun, melakukan penyesuaian pada setiap akhir bulan atau periode, dan akhirnya menghasilkan saldo akhir untuk tujuan laporan keuangan adalah langkah-langkah dalam proses penyusunan laporan keuangan. Teknologi yang terus berkembang berdampak pada prosedur perusahaan yang sudah mapan. Banyak UKM yang saat ini melakukan transisi dari pencatatan keuangan berbasis kertas ke pencatatan keuangan digital dengan bantuan software akuntansi. Program Ipos Professional Store adalah salah satu pilihan perangkat lunak akuntansi, dan ini adalah program toko kasir yang kuat dengan harga murah, mudah dipelajari, dan mudah digunakan. UKM Gusti Karya bergerak di bidang pembuatan kursi, lemari, pintu, dan perabot rumah tangga lainnya. UKM Gusti Karya telah menggunakan Microsoft Excel untuk mengelola administrasi keuangan mereka. UKM Gusti Karya sebelumnya menggunakan sistem akuntansi yang berbeda, namun seiring perkembangan teknologi, mereka meng-upgrade ke ipos. PKM ini bertujuan untuk membiasakan UKM dengan software akuntansi profesional ipos, menjelaskan langkah-langkah yang terlibat dalam pembuatan laporan keuangan, menyebutkan berbagai jenis laporan, dan merinci bagaimana setiap laporan disusun.

Abstract

Kilo Watt Hour Meter or kWh meter is a tool for calculating the amount of electrical energy used by electricity consumers, both residential and industrial customers. The electrical energy used is then converted into the electricity price that must be paid each month. Currently, most kWh meters in circulation are smart kWh, which use electricity tokens as transaction calculations. Customers must fill in 20 token numbers via the kWh meter keypad to fill in electricity tokens. Filling in this 20-digit token is not easy, this is because usually, this type of kWh is placed in a higher place to avoid the reach of children. This placement sometimes causes problems with replenishing the token, and users must start over from the beginning. This research aims to create a tool to fill in electricity token numbers that can be controlled using an Android application, making it easier for users to fill in electricity tokens remotely via smartphone. Apart from that, this system has feedback in the form of notifications that display numbers that failed to be filled in on the kWh meter. Test results show that this system can function well from 10 meters without obstructions and 9 meters without obstructions.

Abstract

Torque ripple analysis and calculation methods in an axial-type Magnetic Gear (MG) design with four rectangular NdFeB magnetic layers have been reviewed and discussed. Smooth and steadily transmitted torque is an essential characteristic of a magnetic gear. Reducing possible mechanical vibration, position inaccuracy, and acoustic noise is necessary. Therefore, this study aims to design a new engineering method appropriate for calculating the torque ripple of the MG transmission by testing its mechanical and electrical properties. Two simultaneous torque tests compare the MG brakes from zero to full load. In addition, the transmission torque of the axial MG is measured and calculated using technical methods. The results showed that differences in dynamic torque occurred in the MG at various air gap distances.

Abstract

Empowering Cooperatives and Micro, Small, and Medium Enterprises (MSMEs) is strategic to boost the national economy. East Nusa Tenggara (ENT), as one of the cooperative provinces, is experiencing rapid growth in both quantity and quality. As pillars of regional and national economics, Cooperatives need to be developed, especially for small communities, in their various productive businesses. The development of cooperatives in NTT Province is quite significant until 2023, namely 4,301. Three thousand eight hundred sixty-six cooperatives are legal entities and active, while 435 cooperatives are not yet legal entities. The Koperasi Simpan Pinjam Sahabat Literasi Flobamorata (KSP Batera) is an institution founded by members who have the same destiny and share the same responsibility in the economic field. Its development is quite advanced regarding assets and the number of members. The main problem faced by KSP Batera is that financial management is still manual, and an Annual Member Meeting (AMM) has yet to be held. This happens because the educational background is inappropriate, and there needs to be more knowledge about the Cooperative Financial Accounting System (CFAS). Training activities for the management team on a computer-based financial accounting bookkeeping system is the best solution for the future development of this cooperative. The final result of the training activity is that the management team can complete a computer-based bookkeeping system and financial reports and prepare AMM reports to be accounted for after the close of the financial year. Maximum knowledge transfer occurs because the learning model in the form of theory and practice is 30% and 70%, respectively. Apart from that, assistance is also provided for managers both offline and online

Abstract

Rooftop Solar Power Plant (PLTS) is one of the renewable energy solutions that support energy efficiency and environmental sustainability. This research is entitled “Operational Analysis of Rooftop Solar Power Plant (PLTS) at GMIT Jemaat Paulus Kupang” and was conducted for four months at GMIT Jemaat Paulus Kupang. The purpose of this research is to analyze the performance and effectiveness of the rooftop solar power system installed in the church. Measurements were made using tools such as Digital Multimeter and Ampere Pliers. This research uses descriptive and quantitative methods, including literature studies, interviews with PLTS management officers, and direct measurements in the field to obtain primary and secondary data related to geographical and weather conditions. The results showed that the performance of the rooftop solar power plant decreased significantly due to factors such as solar radiation intensity, ambient temperature, and the physical condition of the solar panels and inverters. During one week, GMIT Jemaat Paulus Kupang used a total of 561.396 kWh of electrical power to meet load requirements. Of this amount, PLTS supplied 499.2468 kWh of power, while the remaining 62.1492 kWh was supplied by PLN. The excess power generated by the PLTS, because it is greater than the total load demand, is exported back to the PLN network.

Abstract

In the digitalization era, protecting electrical equipment in low voltage systems of 380/220 V is crucial to ensure operational reliability and safety. This study explores the effectiveness of a protection and monitoring system based on the Internet of Things (IoT), integrated with the Telegram application, for detecting disturbances such as overvoltage and overcurrent. The methodology employed is a quantitative experimental design, involving system testing with smart sensors and relays. The test results demonstrate that the system successfully provides real-time notifications to users within an average time of 2 seconds after a disturbance is detected. With this system, users can promptly be informed about voltage and current conditions that may potentially damage equipment, thereby allowing for swift actions to prevent damage. In addition to enhancing responsiveness, this system also facilitates remote management of electrical systems. The findings of this research emphasize the importance of implementing modern technology in electrical system protection, which can reduce the risk of damage and improve energy management efficiency.
