Abstract

The rapid development of digital technology requires vocational high school (SMK) students to have strong basic programming skills, yet algorithmic logic remains a major challenge. This study aims to enhance students’ understanding of basic programming through Flowgorithm training. The training was conducted face-to-face using demonstration and hands-on practice methods involving 32 eleventh-grade students of Software Engineering at SMK Negeri 1 Pangkalan Kerinci. Evaluation results show that most participants agreed the material met their needs and expectations, was engaging and easy to understand, and improved their programming logic skills. The study concludes that Flowgorithm is effective as a visual tool for programming logic. Its implication suggests similar training models can be applied in other vocational schools to strengthen students’ algorithmic thinking foundation.

Abstract

Indonesia dikenal sebagai negara yang kaya akan keanekaragaman hayati, termasuk berbagai tanaman herbal yang tumbuh subur di sana. Tanaman ini, khususnya di Madura, sering digunakan sebagai bahan jamu tradisional yang memiliki potensi sebagai pengobatan herbal. Namun, industri jamu tradisional Madura menghadapi tantangan karena menurunnya minat masyarakat terhadap jamu dan minimnya penjual jamu. Oleh karena itu, diperlukan inovasi untuk melestarikan dan memperkenalkan kembali jamu tradisional, seperti penggunaan mesin penjual otomatis atau vending machine. Vending machine jamu tradisional Madura diuji dengan hasil positif, menunjukkan respons optimal dari semua komponen. Pengaturan water pump dengan delay 15865 ms mencapai takaran air yang diinginkan dengan toleransi ± 3 mL. Untuk deteksi koin, presentase keberhasilan sebesar 86% dapat ditingkatkan dengan penyesuaian delay pada program. Dengan inovasi ini, diharapkan dapat membangkitkan minat masyarakat dan melestarikan kekayaan warisan jamu tradisional Madura

Abstract

Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem pemantauan energi listrik berbasis Internet of Things (IoT) dengan NodeMCU ESP8266, sensor PZEM-004T, serta Automatic Transfer Switch (ATS). Sistem ini didesain untuk meningkatkan efisiensi energi di industri rumahan dengan memanfaatkan dua sumber listrik, yaitu PLN sebagai sumber utama dan Pembangkit Listrik Tenaga Surya (PLTS) sebagai cadangan. Pengguna dapat memantau konsumsi energi secara real – time melalui aplikasi Blynk. Hasil pengujian menunjukkan bahwa sistem ini mampu mengirim data konsumsi energi, dan ATS berfungsi dengan baik dalam mengalihkan sumber daya listrik secara otomatis tanpa gangguan. Dengan pengembangan lebih lanjut, sistem ini berpotensi untuk diintegrasikan dengan penyimpanan energi dan algoritma pengoptimalan, guna meningkatkan efisiensi dan keberlanjutan penggunaan energi pada skala yang lebih luas. Penelitian ini diharapkan dapat memberikan kontribusi dalam penerapan teknologi IoT untuk pengelolaan energi yang lebih efisien di sektor industri.

Abstract

The increasing demand for clean energy in Indonesia has accelerated the deployment of grid-connected photovoltaic (PV) systems. This study presents a technical performance analysis of a 1 MWp grid-connected PV system located in Pangkalan Kerinci, Indonesia, using the PVsyst v7.4.6 simulation software. The system comprises 1818 Trina Solar TSM-DE19-550Wp modules mounted on a fixed-tilt structure (2.2° tilt, 180° azimuth) with two SMA Sunny Central 400 MV-11 inverters (DC/AC ratio = 1.25). Meteorological data from Meteonorm 8.1 (1996–2015) was used to simulate annual irradiation and system output. The results show an annual energy production of 1,404,124 kWh, corresponding to a specific yield of 1,404 kWh/kWp/year. The Performance Ratio (PR) reached 82.75%, indicating high system efficiency under tropical climatic conditions. Loss analysis revealed that thermal losses (9.36%) and IAM losses (2.58%) were the dominant factors, while inverter losses accounted for 2.86%. Module mismatch and wiring losses were minimal at 2.15% and 1.5%, respectively. The high PR and low degradation assumptions confirm the suitability of the selected configuration for equatorial regions. This study provides a robust technical benchmark for similar PV installations in Sumatra and supports optimal design decisions for future utility-scale solar projects in Indonesia.

Abstract

Access to clean water in remote tropical regions remains a critical challenge, particularly where grid electricity is unavailable. Solar photovoltaic (PV) water pumping systems offer a sustainable, off-grid solution. This study evaluates the technical performance of a 250 Wp PV-powered deep well water pumping system installed in Pangkalan Kerinci, Indonesia (0.41°N, 101.85°E). The system employs a single Trina Solar TSM-310PD14 module connected to a Sun Pumps SDS-D-128 DC membrane pump via an MPPT controller. Using PVSyst v7.4.6, a one-year simulation was conducted under realistic meteorological and hydraulic conditions, including a static water table at 4 m depth and a daily water demand of 0.30 m³. Results indicate that the system reliably meets annual water needs (109 m³/year) with negligible water deficit (0.163 m³, or 0.15%). The annual specific water yield is 522 m³/kWp/bar, while the system operates at an overall efficiency of 4.3% and a pump efficiency of 16.7%. Energy analysis shows 15.5 kWh/year delivered to the pump, with 42.6 kWh/year of excess solar energy unused due to tank capacity limits. The performance ratio (PR) is approximately 87%, confirming high system reliability in equatorial conditions. This study demonstrates the technical viability of small-scale solar pumping for rural water supply in Indonesia.

Abstract

Sistem otomasi industri modern mengandalkan logika kendali berurutan yang responsif terhadap umpan balik sensor posisi. Namun, pemahaman konsep ini masih terbatas di kalangan mahasiswa akibat minimnya modul praktikum berbasis sensor. Penelitian ini bertujuan mengimplementasikan kendali berurutan otomatis menggunakan limit switch sebagai sensor posisi pada modul praktikum PLC portabel berbasis Omron CP1E. Metode penelitian mengikuti pendekatan Research and Development (R&D) yang meliputi perancangan, perakitan, pemrograman ladder diagram, dan pengujian fungsional berulang. Sistem dirancang agar satu perintah start memicu siklus penuh: Cylinder 1 maju, menekan limit switch open, Cylinder 2 maju, Cylinder 1 mundur, Cylinder 2 mundur, lalu mengulang hingga timer habis. Hasil pengujian menunjukkan bahwa seluruh transisi gerak terjadi secara akurat sesuai urutan yang diprogram, tanpa miss-trigger maupun intervensi manual. Temuan ini membuktikan bahwa integrasi limit switch dengan PLC mampu merealisasikan kendali closed-loop sederhana yang andal. Modul ini memberikan pengalaman belajar autentik dan direkomendasikan sebagai media pembelajaran kendali berbasis kondisi nyata di pendidikan vokasi.

Abstract

Conventional hydroponic farming systems frequently encounter limitations related to unstable environmental control, suboptimal nutrient management, and strong dependence on grid-based electricity, which collectively hinder their sustainability and scalability, particularly in remote or energy-constrained regions. Recent studies have explored smart hydroponic technologies. However, many remain reliant on external power sources or lack integrated, autonomous control of multiple critical growth parameters. Therefore, this problem reveals a research gap in the development of fully self-powered and intelligent hydroponic systems. This study proposes the design and implementation of a solar-powered, IoT-based smart hydroponic farming system that enables real-time monitoring and closed-loop environmental control. The system integrates multi-sensor measurements, including pH, DS18B20 temperature, total dissolved solids (TDS), and light-dependent resistor (LDR) sensors, coupled with an on–off control strategy to regulate light intensity (115 ADC), water temperature (28 °C), pH (5.5-6.5), and nutrient concentration (840 ppm). A standalone photovoltaic energy subsystem, consisting of a 100 Wp solar panel and a 65 Ah battery, was designed based on a daily energy demand of 378.85 Wh to ensure continuous autonomous operation. Experimental results demonstrate high sensor accuracy, with measurement errors of 0.75% for pH, 0.095% for TDS, and 0.24% for temperature. Moreover, the proposed system effectively stabilizes environmental parameters within predefined setpoints, outperforming uncontrolled conditions. These findings confirm the system’s reliability and potential as a sustainable precision agriculture solution for off-grid hydroponic applications.
