Abstract

The rapid development of electronic systems has increased the need for accurate frequency measurement because many electrical and digital devices depend on stable operating frequencies for proper performance. In routine laboratory and field work, digital multimeters are frequently used for frequency checks due to their practicality and availability, yet their readings may be affected by signal conditions and instrument processing limits. This study aims to assemble and evaluate a low-cost digital frequency counter based on the PIC16F628A microcontroller for measuring crystal oscillators and external frequency signals, while benchmarking its readings against a digital multimeter. An experimental quantitative approach was applied that included hardware assembly, schematic reconstruction through PCB trace inspection, block-level functional analysis, and measurement testing using five crystal oscillators and externally generated reference signals derived from a 32.768 kHz source with frequency division. Data were recorded across test points from 1 Hz to 32.768 kHz and summarized through direct comparison between nominal frequencies and instrument readings. The frequency counter produced readings that matched the nominal test frequencies across all external test points within the display resolution limits. Crystal testing also yielded values close to nominal specifications (e.g., 8.0002 MHz for 8 MHz and 11.998 MHz for 12 MHz). The digital multimeter showed small frequency-dependent offsets at higher test points (e.g., 32.770 kHz at 32.768 kHz). These results indicate that the dedicated counter delivers stable measurements across the evaluated range. This work offers a practical reference for electronics education and routine verification by combining schematic reconstruction, reproducible block-level documentation, and empirical validation of a kit-based instrument, providing added value beyond prior studies that emphasize either theory or new system design.

Abstract

Electrical installation systems in healthcare facilities must ensure safety, reliability, and operational continuity because medical services depend on stable power supply and adequate lighting conditions. In polyclinic environments, electrical disturbances may affect service quality and patient safety, making proper system design essential. Objective: This study aims to design and evaluate the electrical installation of the Cibubur Hospital Polyclinic based on national standards, focusing on load distribution, lighting performance, backup power systems, and grounding effectiveness. Method: This research employs a mixed qualitative–quantitative descriptive approach. Data were collected through field observations, direct measurements using electrical instruments (clamp meter, lux meter, and earth tester), and documentation review of installation layouts and technical standards. The analysis was conducted through technical calculations and standard-based evaluation. Results: The total electrical load is divided into 11,883 W for normal PLN load and 7,406 W for priority UPS load, indicating a functional separation between general and critical services. Lighting measurements show that seven out of ten rooms meet the required standards, while three rooms remain below the threshold. The grounding system demonstrates resistance values well below the allowable limit, indicating effective protection performance. Implications: The results indicate that integrated electrical installation design can support safe and continuous healthcare operations, although improvements in lighting uniformity and system specification consistency are still required. Originality: This study offers an integrated evaluation of load distribution, lighting, backup power, and grounding within a single polyclinic case study, providing practical and academic contributions to electrical system design in healthcare facilities.

Abstract

Energy efficiency in office buildings has become a critical issue due to increasing electricity consumption, particularly in lighting systems that operate continuously. Inefficient lighting design can lead to excessive energy use, higher operational costs, and reduced sustainability performance in commercial buildings. Objective: This study aims to analyze the implementation of Light Emitting Diode (LED) technology to improve energy efficiency in office lighting systems using DIALux simulation, while ensuring compliance with standard illumination requirements. Method: This research employs a quantitative descriptive approach supported by simulation modeling. Data were collected through field observation, illumination measurement using a lux meter, and documentation of room specifications. The analysis was conducted using DIALux software to evaluate illuminance levels, light distribution, and energy consumption based on office lighting standards. Findings: The results indicate that the LED lighting system achieves an average illuminance of 340 lux, which meets the SNI 6197:2011 standard (300–500 lux), with a uniformity ratio of 0.68 indicating adequate light distribution and visual comfort. The system consumes 36 kWh per month, which is more than 50% lower than conventional fluorescent (TL) lighting systems. Implications: The findings suggest that LED lighting systems can provide efficient and compliant lighting solutions while significantly reducing energy consumption and operational costs. This supports the implementation of energy-efficient and sustainable building practices. Originality: The originality of this study lies in its integrated approach that combines room characteristics, LED configuration, and DIALux simulation to evaluate lighting performance and energy efficiency simultaneously, offering a practical framework for office lighting design.

Abstract

Program pengabdian masyarakat ini dilatarbelakangi oleh rendahnya tingkat kepatuhan pajak di kalangan pelaku Usaha Mikro, Kecil, dan Menengah (UMKM) akibat kurangnya pemahaman terhadap kewajiban perpajakan dan keterbatasan akses informasi. Urgensi kegiatan ini terletak pada perlunya peningkatan literasi pajak agar UMKM dapat melaksanakan kewajiban perpajakan dengan benar dan berkontribusi terhadap penerimaan negara serta pertumbuhan ekonomi lokal.Tujuan kegiatan ini adalah memberikan edukasi dan sosialisasi mengenai pentingnya kepatuhan pajak, jenis dan tarif pajak yang berlaku bagi UMKM, serta pemahaman tentang prosedur pelaporan pajak sesuai peraturan yang berlaku. Kegiatan dilaksanakan di Graha Wiranesia, Pasar Minggu, Jakarta Selatan, dengan melibatkan 21 pelaku UMKM dari sektor industri dan kuliner. Metode pelaksanaan menggunakan pendekatan ceramah interaktif, diskusi, dan tanya jawab untuk memperkuat pemahaman peserta terhadap konsep perpajakan. Pendekatan ini dirancang agar peserta lebih mudah memahami materi tanpa harus melalui tahapan simulasi teknis. Luaran yang ditargetkan dari kegiatan ini adalah meningkatnya pengetahuan dan kesadaran peserta terhadap kepatuhan pajak. Program ini diharapkan dapat menjadi langkah awal dalam membangun budaya kepatuhan pajak dan mendukung kemandirian finansial UMKM guna memperkuat pertumbuhan ekonomi daerah..

Abstract

Di era sekarang, santri tidak hanya perlu memahami ilmu agama, tetapi juga perlu memiliki kemampuan mengelola keuangan agar lebih mandiri di masa depan. Pondok Pesantren Quantum Idea di Jl. Camar No. 101, Kelurahan Jatiraden, Kecamatan Jatisampurna, Kota Bekasi, Jawa Barat, berkomitmen membekali santrinya dengan pengetahuan karakter, kewirausahaan, dan keterampilan praktis. Program Edukasi Pencatatan Keuangan Sederhana Berbasis Kas ini muncul karena banyak santri yang semangat berwirausaha, tetapi masih kesulitan dalam mencatat dan mengelola keuangan dengan baik. Kurangnya pemahaman tentang literasi keuangan membuat arus kas, keuntungan, dan modal sulit dipantau. Padahal, pencatatan kas yang rapi penting agar usaha pesantren bisa berjalan dengan stabil dan berkelanjutan. Tujuan kegiatan ini adalah meningkatkan kemampuan santri dalam memahami konsep dasar arus kas dan membuat laporan keuangan sederhana sesuai prinsip syariah. Santri akan belajar mencatat kas masuk dan keluar secara manual maupun digital serta menerapkan perencanaan keuangan untuk usaha maupun kebutuhan pribadi. Kegiatan dilakukan melalui beberapa tahap, yaitu sosialisasi, pelatihan interaktif dengan contoh usaha pesantren, pendampingan praktik pencatatan, dan evaluasi hasil belajar melalui pre-test dan post-test.
