ABSTRACT Hybrid natural-natural fibre reinforced polymer composites become attractive alternative to seek the friendly-environmentally materials. Study on the durability level of the hybrid composites have the importance reason due to the role in application as structural function. This study focuses on examining the fatigue strength of polypropylene polymer composites reinforced with hybrid sugar palm-kenaf fibres. The hybrid composite materials were prepared by mixing the fibres and matrix with several compositions. There are five composition types of specimens that evaluated, such as 70:10:10, 70:15:15, 70:20:10, 80:10:10 and 90:5:5. The hybrid composites were composed by PP, sugar palm fibre and kenaf fibre. Furtheremore the tensile test were conducted to find the value of ultimate tensile strength for every specimens of hybrid composites. The fatigue test also were conducted with four level of stress i.e. 80%, 70%, 60% and 50%. The results show that in the lower level of stress, the hybrid composites with higher content of sugar palm fibre posses the better performance of fatigue life compare to the others

Currently using electrical energy is very large and electrical energy security continues to be studied by government. Developments starts from using and managing of renewable energy sources. Energy sources will not be run out. One of which is using heat energy from sunlight. Using The use of the concept of renewable energy utilization strategy is still 17%. The energy management method is to use a smart system where if the room is during the day, the LDR sensor will signal to the microcontroller so that the room lights will turn off and if there is heat the DHT22 sensor detects the room temperature of 300 C. Then the fan turns on and cools the room so that it will cool down and the load that is not needed by the grid will not function so that energy consumption will be reduced according to calculated needs. This working system is based on IOT derived from ESP 8266 to store solar energy consumed by the house room. The smart method used in the research is to place 3 DHT22 sensors for optimal heat temperature. Average temperature sensor data, LDR data is stored in the data logger in the form of xls files on Gdrive. xls files then for 15 days. From the results of the date per 15 days on 13-11-2023, the design obtained an average temperature of 30.90 with a consumption of 5.83 kWH at a cost of 7882.16 rupiah.

Undang-Undang Republik Indonesia Nomor 18 Tahun 2012 tentang pangan. Pembangunan Nasional merupakan pencerminan kehendak seluruh rakyat untuk terus-menerus meningkatkan kemakmuran dan kesejahteraannya secara adil dan merata dalam segala aspek kehidupan yang dilakukan secara terpadu, terarah, dan berkelanjutan dalam rangka mewujudkan suatu masyarakat yang adil dan makmur, baik material maupun spiritual berdasarkan Pancasila dan Undang-Undang Dasar Negara Republik Indonesia Tahun 1945. Pangan merupakan kebutuhan dasar manusia yang paling utama dan pemenuhannya merupakan bagian dari hak asasi setiap rakyat Indonesia. Pangan harus senantiasa tersedia secara cukup, aman, bermutu, bergizi, dan beragam dengan harga yang terjangkau oleh daya beli masyarakat, serta tidak bertentangan dengan agama, keyakinan, dan budaya masyarakat. Untuk mencapai semua itu, perlu diselenggarakan suatu sistem ketahanan pangan yang memberikan pelindungan, baik bagi pihak yang memproduksi maupun yang mengonsumsi pangan. Penyelenggaraan pangan dan pengolahan hasil perikanan memegang peranan penting dalam kegiatan pascapanen, mengingat hasil perikanan merupakan komoditi yang sifatnya mudah rusak (perishable goods). Maka perlu dilakukan kegiatan penyuluhan pelaksanaan sosialisasi pengeringan pada ikan dilakukan dengan proses pengeringan Standar Operasional Prosedur Pengembangan Prototipe Pengering Ikan Kayu Sistem Kontrol Dual Energi.

The utilization of wind energy as one of the renewable energy sources in Indonesia is still limited. This is due to Indonesia's large wind potential, but it is at low speeds. One modification of wind turbines to overcome this problem is by using inverse taper and taper blades. Inverse taper blades have a chord distribution that increases from root to tip while taper blades have a chord distribution that decreases from root to tip. This research conducts the design and construction of inverse taper and taper blades on small-scale wind turbines using NACA 6412 airfoil type, then tested in the field and obtained the performance of each blade. The design was carried out using blade element momentum theory to obtain the blade geometry shape and perform performance analysis of each type of blade. Based on the simulation results obtained from QBlade, it shows that the inverse taper blade performance has a maximum Cp of 0.52 while the taper blade has a maximum Cp of 0.41. The power graph from field testing results shows that inverse taper blades provide good power generation at low wind speeds compared to taper blades. The inverse taper blade has a cut-in speed of 1.2 m/s and the best power production occurs at speeds of 1-4 m/s.

Pintu bendungan memiliki peran strategis dalam pengelolaan sumber daya air, mencakup irigasi, pengendalian banjir, hingga penyediaan air bersih bagi masyarakat. Namun, di banyak daerah, sistem pengoperasian pintu masih bersifat manual dan sangat tergantung pada intervensi manusia. Ketergantungan ini menyebabkan keterlambatan dalam merespons fluktuasi volume air secara tiba-tiba, terutama pada saat cuaca ekstrem, yang berisiko menimbulkan bencana seperti banjir dan kekeringan. Penelitian ini bertujuan untuk merancang dan mengembangkan sistem otomatisasi pintu bendungan berbasis Internet of Things (IoT), dengan menggunakan mikrokontroler NodeMCU ESP8266 sebagai unit kendali utama. Sensor ultrasonik digunakan untuk mengukur ketinggian permukaan air secara real-time, sementara sensor hujan memantau kondisi cuaca. Sistem ini dilengkapi panel surya sebagai sumber energi terbarukan guna mendukung keberlanjutan operasional. Motor servo digunakan untuk membuka dan menutup pintu bendungan secara otomatis berdasarkan data sensor yang dianalisis secara cerdas. Seluruh data dikirimkan ke aplikasi Blynk, memungkinkan pemantauan dan pengendalian jarak jauh melalui perangkat seluler. Hasil pengujian menunjukkan bahwa sistem ini bekerja secara akurat, responsif, dan andal dalam berbagai kondisi simulasi. Temuan ini menawarkan solusi teknologi yang inovatif, hemat energi, dan berpotensi diterapkan secara luas dalam sistem pengelolaan air terpadu di masa depan.

At this time, electricity has become a primary need for the community, the existence of the State Electricity Company (PLN) is very supportive of all community activities. The high use of electricity can cause negative effects for users, where the higher the use of electricity, the greater the costs incurred. This is what triggers the emergence of things that are not wanted in society. One of them is the emergence of a desire to steal electric current. In general, people do not know what the risks are due to stealing the electric current. In addition, there are other ways to reduce excessive use of electricity, one of which is by assembling a solar micro-power plant, of which not many people know about the use of assembling the power plant. Based on this, service is carried out with the aim of providing explanations and adding knowledge to the community in the safe use of electrical energy; provide explanations and increase knowledge for the public about the risk of theft of electrical energy; increase community participation in using and protecting the environment by using alternative energy; foster a strong bond between the Blang Pulo gampong which is the closest village to the Malikussaleh University Bukit Indah campus and the Malikussaleh University academic community, especially the electric energy-saving extension team. The counseling activity on the risk of theft of PLN flows in the village of Blang Pulo is carried out in the following activity methods: Program introduction, assembly and delivery of various forms of energy, especially solar energy; The submission of a frugal living attitude according to Islamic law is accompanied by showing several verses of the Koran and hadith and conveying the risks due to stealing electric current. The expected results of this service are through the micro-solar electricity empowerment program and energy-saving counseling, It is hoped that the awareness, sensitivity and participation of lecturers and the community of Blang Pulo will grow and develop in the safe and efficient use of electrical energy so that there is an adequate supply of electricity and there will be no longer rotating blackouts caused by the limited supply of electricity from the PLN, and explain the consequences if electrical energy is stolen for personal or group use in order to be able to use electrical energy for free.
