Abstract

Efforts and strategies have been done both by the providers of electrical energy and the government to handle the increase in electricity demand.  However, there has been no satisfactory result. The government has set a major policy on energy management, namely conservation and energy diversification in order to reduce dependence on non-renewable energy sources and utilize renewable energy available in areas where power plants will be built to meet the growing demand for electricity. Riau Province in addition to located in tropical climates and many of its areas are on the coast that its existence is very far for affordable network of PLN electricity, therefore the provision of solar power plant is one appropriate alternative, to meet the needs of electrical energy for the needs of the population. While the output voltage generated by solar cells is not constant, but it depends on the natural conditions that at any time vary the intensity of sunlight, so that the output voltage of the solar cell is also not constant and varies throughout the daytime. In general, commercial equipment has specification limits for ± 10% voltage variation. Disturbances such as voltage varization, if not handled seriously can cause damage to consumer electrical equipment, in addition to the use of electrical energy, in the form of varying output voltage resulting in expensive cost. To overcome the problem of voltage variations produced solar cell can be used prototype dc to dc converter using boost converter technology, which  automatically  adjust  the  output  voltage  according  to  the  desired  voltage.Designing  DC  to  DC Converters To Stabilize Solar Cell Outputs Using Boost Converter Technology has been tested for performance through the output voltage of a 100 WP solar cell panel whose values vary from 13.5 volts to 20.8 volts as a boost converter input and produce a regulated output voltage 24 volt. Based on the results of prototype testi ng dc to dc converter using booast converter technology that has been designed to produce a voltage regulated voltage of 24 volts direct current declared valid. The valid intent here because the output voltage is still dirange 24 volts ± 10%.

Abstract

Pengabdian kepada mayarakat ini dilaksanakan di Desa Bunsur Kecamatan Sungai Apit Kabupaten Siak Propinsi Riau dengan khalayak sasarannya masyarakat nelayan desa tersebut. Sektor pertanian dan nelayan merupakan profesi yang sangat dominan sebagai sumber kehidupan di desa ini. Berdasarkan informasi kepala desa, desa ini terkenal sebagai penghasil ikan Bilis Asam. Berdasarkan hasil survei harga jual ikan ini di Pasar Panam Kota Pekanbaru berkisar Rp. 125 ribu per kg. Harga ini menunjukkan nilai keekonomian yang tinggi dan sangat menjanjikan bagi kehidupan masyarakat nelayan di Desa Bunsur ini. Dari informasi para nelayan, pada musim hujan semua hasil tangkapan ikan ini tidak dapat dijual bahkan dibuang begitu saja karena membusuk akhibat tidak bisa dikeringkan karena tidak ada cahaya matahari. Keadaan ini dapat diatasi dengan membuat sebuah tempat pengeringan khusus dengan teknik rekayasa cahaya lampu dalam sebuah ruangan yang dirancang sedemikian rupa. Ruangan ini akan dapat menyelamatkan gagal produksi ikan Bilis Asam masyarakat nelayan di Desa Bunsur dengan demikian kehidupan mayarakat nelayan dapat lebih stabil di setiap musim, baik musim hujan maupun musim panas. Pengeringan ikan yang akan dirancang adalah tipe pengeringan mekanis dengan rekayasa cahaya lampu. Pengeringan ikan ini akan dibuat transparan yang dikelilingi akrilik bening dan tembus cahaya. Penjemuran tembus cahaya ini bertujuan agar di musim panas masyarakat juga tetap menggunakan penjemuran ini.  Penjemuran ini akan dipasang sensor sehingga pada saat hujan atau panas pengeringan tetap berfungsi dengan baik dan otomatis. Sistem ini dirancang agar nelayan tidak perlu kuatir ikannya terkena hujan atau tidak kena panas karena sudah beroperasi secara otomatis

Abstract

Stunting is a public health problem that must be taken seriously. Toddlers who experience stunting have a lower level of intelligence, making children more susceptible to disease and in the future may be at risk of decreasing productivity levels. At the end, stunting broadly can inhibit economic growth, increase poverty and widen inequality. Sustainable education is considered to be one way to reduce stunting rates. This service has the aim of increasing public knowledge including adolescents, pregnant women, and Posyandu cadres. Therefore, all of them can recognize stunting, have knowledge to prevent and manage stunting. The material of training is given to 20 participants in 60 minutes. The knowledge level of participants is measured before and after this activity through Pretest and Posttest. The results of the pretest shows that 4 participants have good knowledge, 12 participants had moderate knowledge, and 4 participants had poor knowledge. The level of knowledge increased after the presentation of the material, also through the question and answer session, namely 15 participants had good knowledge, and 5 participants had moderate knowledge. This activity succeeded in increasing public knowledge.
