Abstract

Penggunaan material plastik dan komposit polimer semakin massif di berbagai aplikasi khususnya  industri otomotif. Berbagai rekayasa dan penelitian telah mampu menghasilkan karakteristik mekanis dan fisis material plastik yang mampu menggantikan material logam. Namun demikian, penggunan plastik pada aplikasi dengan resiko kebakaran perlu melalui pengujian hambat bakar. Pengujian tersebut menghasilkan tingkat kemampuan material menghambat laju pembakaran serta penundaan waktu penyalaan api. Metode pengujian tersebut salah satunya diatur di dalam standar UL 94 AVH. Untuk mendapatkan hasil yang akurat serta memberikan kemudahan dalam mengoperasikan, maka perlu dibuat sebuah alat uji laju dan waktu pembakaran plastik pada arah horizontal. Artikel ini membahas proses hingga unjuk kerja alat dengan tetap berdasar pada  standar yang diacu. Proses manufaktur alat uji dimulai dengan observasi, pembuatan desain alat dan skematik pemantik otomatis, machining komponen, wiring kelistrikan, perpipaan dukungan gas, assembly, dan finishing. Hasil pengujian menunjukkan bahwa alat uji laju pembakaran ini dapat digunakan secara akurat dan menunjukkan perbedaan laju pembakaran setiap specimen uji dengan material dasar yang berbeda.

Abstract

MI (Madrasah Ibtidaiyah) Nurul Huda represents a formal educational institution situated in Pulutan Village, Nogosari District, Boyolali Regency. The institution offers a comprehensive curriculum encompassing general education and Islamic religious studies. Notably, the school includes science as one of its core subjects. Through interviews with stakeholders, particularly Mrs. Basuki, it has been identified that the current challenge faced by the school is the effective dissemination of science knowledge to students. This predicament arises from the limited availability of science teaching aids, hindering the practical delivery of educational material. The primary objective of this Community Service Program (PKM) is to facilitate the distribution and training in the utilization of light-reflecting props at MI Nurul Huda. The initiative aims to address the aforementioned challenge by providing teachers with valuable tools to enhance the practicality of material delivery, with a specific focus on the topic of light reflection. It is anticipated that the incorporation of these teaching aids will not only assist educators in conveying scientific concepts effectively but will also contribute to a more accessible learning experience for the students

Abstract

Permasalahan utama pada UKM pembibitan ikan patin Bapak Priyanto muncul ketika menggunakan water level control pabrikan umum adalah sengatan atau hubung singkat di air, usia sensor terbatas 3 bulan saja dan usia pompa air terbatas hanya 1 tahun. Tujuan utama dari penerapan alat pengendali pompa air 2 pk sistem mikrokontroler ini adalah untuk menentukan kenaikan debit pompa yang efektif. Metode yang dilaksanakan adalah dengan merumuskanmasalah bersama tim dan mitra dalam menentukan alat pengendali otomatis memanfaatkan sensor ketinggian air untuk mementukan kondisi kerja pompa air dengan proses transmisi arus DC menuju pengolah mikrokontroler untuk menggerakkan antarmuka elektromekanik. Hasil yang dicapai adalah volume tandon air bisa dipantau dengan cermat dan penyalaan pompa berdaya besar tidak mengganggu kinerja sensor, sehingga debit pompa naik 28%. Dengan dilengkapi instalasi yang sinkron antara kebutuhan listrik dengan kemampuan daya listrik di mitra, maka temperatur switch dan tekanan air terkendali baik dan pompa, instalasi alat lebih tahan lama (harapan efektif maksimal 18.000 jam pemakaian).

Abstract

Child malnutrition, particularly stunting, remains a critical public health issue with long-term effects on growth and cognitive development. In many community health settings, conventional anthropometric measurement tools used in community health services often present challenges, including human measurement error, non-standard data recording, and a lack of real-time diagnostic output. This study aims to develop and validate a portable ultrasonic sensor-based digital anthropometric system capable of automatically detecting the Composite Index of Anthropometric Failure (CIAF) in real-time. The novelty of this research lies in integrating non-contact ultrasonic height measurement with automated CIAF classification based on WHO 2006 growth standards, cloud-connected data storage, and a user-friendly interface designed for community health workers. This Research and Development study involved system design, laboratory calibration, field validation, and user acceptability testing. A total of 80 toddlers and 30 users (midwives, nutritionists, and Posyandu cadres) participated across regions with low and high stunting prevalence. Measurement accuracy was compared to gold-standard anthropometry, while usability was assessed through a Likert-scale evaluation. Laboratory tests indicated measurement error ranging from 0.0 to 0.2 cm, indicating high sensor precision. Field tests showed a mean difference of ≤1 cm with no statistically significant difference (p>0.05) compared to standard measurement. User evaluation reported high satisfaction, particularly in ease of use (92%), accuracy (90%), and program support benefit (94%). The developed portable ultrasonic digital anthropometry system provides accurate, fast, and standardized CIAF-based malnutrition detection, supporting more efficient child growth monitoring programs. The tool demonstrates strong potential for integration into community-based nutrition surveillance and national health information systems.

Abstract

Infant body temperature stability is paramount, especially for preterm newborns unable to maintain their own thermal equilibrium. Here, we explore a Proportional-Integral-Derivative (PID) control algorithm implemented directly on a Nextion Human–Machine Interface (HMI) to regulate infant warmer temperature. Unlike typical systems where the microcontroller holds the major PID calculation and the HMI acts as a display only, this method integrates the PID logic into the HMI itself, with possible reductions of microcontroller load, minimization of communication delays, and hardware architecture simplification. Three trials at a constant setpoint of 37 °C with varying combinations of PID gains were used with a fixed experimental setup. Temperature response indicators like rise time, settling time, percent overshoot, and steady-state error were measured and compared. Results indicate that with gains of Kp = 1.50, Ki = 0.05, and Kd = 1.50, the system reached a steady state of 36.97 °C with just 2.16 % of an overshoot and a settling time of about 7 minutes and satisfied neonatal warmer requirements. The results confirm that PID control executed directly on the Nextion HMI can achieve temperature regulation performance comparable to conventional microcontroller-based implementations while improving system simplicity and code efficiency. It presents a good alternative choice of low-power and portable infant warmer and also of other embedded hot and cold control systems.
