Abstract

Recently, the technology of membrane is developed directly. Many attractive things of membrane is able to be studied, therefore many ideas emerged on the aspect of synthetic membrane fabrication from many materials, furthermore it is able to used substituting for the function of natural membrane. The purpose of this study are able to know and study the influence of the TiO2 additional on the compounds of the nylon thread in market and on the characteristic of electricity and mechanics. The membrane was fabricated by a phase inversion method on weight variation. The characterizations were done which were the characteristic of electricity (impedance, capacitance, conductance and loss coefficient), the characteristic of mechanics (compression and attraction) and the analysis of on the compounds of the nylon membrane using FTIR. The most optimum characteristic of mechanics are the membrane with nylon weight of 3.5 g and 6.0 g, furthermore from the mechanics characteric was treated the TiO2 dopping. the compounds of the nylon membrane was observed by using FTIR which showed that exist PO4 in the natural membrane and the TiO2 dopped membrane

Abstract

Sistem dinamik adalah sebuah metode analisa masalah dengan memodelkan sistem dengan faktor utama adalah waktu. Model ini kemudian dikembangkan untuk mengkaji sistem pada bidang sosial, kesehatan, teknik, dan lingkungan. Paper ini bertujuan untuk mengembangkan model sistem dinamik pada sistem yang ada di bidang fisika, sehingga dapat digunakan sebagai salah satu media pembelajaran. Pada paper ini, akan digambarkan beberapa contoh sistem dinamik pada bidang fisika seperti hukum kedua Newton dan persamaan gerak linear pada partikel.

Abstract

Ciramahilir Village in Purwakarta Regency faces a serious problem due to the lack of street lighting, which negatively impacts the safety, comfort, and socio-economic activities of the community. This community service program aimed to improve the quality of life for residents by installing solar-powered street lights at strategic locations within the village. The approach used was Participatory Action Research (PAR), involving the community actively in every stage of the program—from problem identification and planning to implementation and evaluation. The results show that the street lighting intervention had a positive impact on residents' sense of security, increased night-time activities, and strengthened collective awareness to maintain public infrastructure. Additionally, technical training and assistance enhanced the community's capacity to sustain the installed systems. This activity also demonstrated that appropriate renewable energy technology can serve as an effective tool for promoting sustainable social change in rural areas.

Abstract

Maintaining stable cage temperature is a crucial factor in the success of broiler chicken farming, especially in close house systems that rely on optimal microclimate control. Temperature instability can lead to thermal stress, reduced growth rates, and increased mortality in broilers, particularly during the early stages of life (0 to 30 days old). This study aims to design and implement an automatic temperature control system based on the Arduino Uno microcontroller integrated with a DHT11 temperature and humidity sensor in the broiler chicken cages of PT. Barokah Restu Utama. The system is designed to read temperature and humidity in real-time and automatically activate or deactivate cooling devices such as fans or heating devices like incandescent lamps, depending on the temperature range required for each growth phase. The ideal temperature range used as a reference in this system includes 30–32°C for chickens aged 0–7 days, 29°C for ages 8–14 days, 28°C for ages 15–21 days, and 26–27°C for chickens aged 22–30 days. Testing results show that the system is capable of maintaining stable temperatures according to the specified standards for each growth phase. With this automatic control system in place, broiler chicken maintenance becomes more efficient and effective. The risk of mortality due to heat stress is significantly reduced, and chicken growth becomes more optimal. This technology offers a practical and economical solution, especially for small- to medium-scale broiler chicken farmers who use close house systems. The system is easy to operate and relatively affordable to install, making it an accessible innovation that supports better livestock management through automation and smart farming practices.

Abstract

Perkembangan teknologi informasi dan elektronika telah mempercepat inovasi dalam sistem berbasis komputer, terutama dalam bidang instrumentasi dan otomatisasi. Sistem alarm kebakaran adalah salah satu aplikasi penting yang membutuhkan deteksi dini untuk mencegah kerugian material dan jiwa akibat kebakaran. Penelitian ini bertujuan untuk merancang dan mensimulasikan sistem alarm kebakaran berbasis Arduino yang terintegrasi dengan LabVIEW. Sistem ini menggunakan berbagai sensor, termasuk sensor suhu, asap, dan nyala api, yang dipantau secara real-time melalui antarmuka LabVIEW. Hasil implementasi menunjukkan bahwa sistem dapat mendeteksi indikasi kebakaran secara efektif, memberikan peringatan secara visual dan audio. Dengan menggunakan 36 sensor suhu, 7 sensor asap, dan 8 sensor api, serta dukungan dari anggota keluaran visual seperti LED dan buzzer, sistem ini telah diuji di miniatur gedung dengan 12 ruangan. Dengan desain yang efisien dan biaya yang terjangkau, diharapkan sistem ini dapat diterapkan di berbagai lingkungan, termasuk rumah tinggal dan area industri, sebagai solusi mitigasi bencana kebakaran yang efektif.
