Abstract

Korosi merupakan penurunan mutu logam yang diakibatkan oleh lingkungan atau zat kimia dan berpengaruh pada kondis suatu material, demikian halnya pada baja komersil. Beberapa faktor yang berpengaruh terhadap laju korosi diantaranya salinitas, pH, temperatur dan kelarutan oksigen dalam media korosi. Pada penelitian ini digunakan impeller (sudu-sudu) pompa berbahan stainless steel sebagai sampel penelitian dengan variasi kecepatan motor penggerak sebesar 0 rpm,1430 rpm, 1465 rpm, dalam pengujian weigh loss (kehilangan berat) yang dilakukan selama 50 jam. Dari hasil penelitian maka di dapatkan hasil korosi terbesar terjadi pada kecepatan motor penggerak tertinggi yaitu 1465 rpm dan dengan hasil produk korosi sebesar 0,038 mm/y, yang selanjutnya di ikuti kecepatan motor sebesar 1430 rpm dengan laju korosi sebesar 0,027 mm/y dan kemudian laju terendah terjadi pada putaran motor penggerak dengan kecepatan 0 rpm dengan laju korosi sebesar 0,020 mm/y.

Abstract

Pemanfaatan energi matahari untuk pencahayaan alami di bangunan rumah toko (ruko) melalui implementasi sistem top lighting menggunakan material kaca 12 mm. bertujuan untuk menghemat konsumsi energi listrik yang signifikan di siang hari, terutama pada ruko yang seringkali minim bukaan. Pendekatan ini memanfaatkan prinsip refleksi cahaya melalui kaca, sesuai dengan Hukum Fresnel, untuk mendistribusikan cahaya matahari secara efektif ke dalam ruangan. Pengukuran tingkat pencahayaan alami dibandingkan dengan cahaya tambahan dilakukan sepanjang hari pagi, siang, dan sore dengan referensi standar SNI untuk pencahayaan yang optimal dan nyaman. Data menunjukkan bahwa di pagi hari, cahaya tambahan melengkapi cahaya alami yang rendah (190-200 Lux), sementara di siang hari (550-600 Lux), ketersediaan cahaya alami sangat tinggi, meskipun data cahaya tambahan (517-150 Lux) memerlukan klarifikasi. Di sore hari, cahaya tambahan digunakan untuk mempertahankan iluminasi seiring penurunan cahaya alami. Grafik intensitas cahaya lebih lanjut memvisualisasikan fluktuasi ini, termasuk puncak 517 Lux yang sesuai dengan pengukuran cahaya tambahan. Hasil penelitian ini menegaskan potensi top lighting kaca sebagai solusi efektif untuk mencapai efisiensi energi dan memenuhi standar pencahayaan di bangunan komersial.

Abstract

The grounding system is one of the security systems in substations to channel excess voltage caused by lightning strikes that occur at substations, as well as electrical equipment. To design a grounding system, there are several factors that must be considered, including the type of soil, the configuration of the grounding system, the resistivity of the soil, and the condition of the surrounding environment. The aim of this research is to determine the safe limits in the substation grid grounding system which is influenced by the type of soil and influences the touch voltage and step voltage, which can be dangerous to humans. The method used is simulation with the Finite Element Method (FEM) in the ETAP application. Finite Element Method (FEM) is a method that uses image mediation by assuming that the grounding system is an equipotential structure. The test results were deliberately carried out with larger substation area parameters and different soil types, so that the differences between the influence and appearance of touch voltage and step voltage can be seen clearly.

Abstract

Community Service Activities for Salt Farmers to Increase Salt Production in Paluh Sibaji Village, Pantai Labu District, Deli Serdang Regency, North Sumatra were carried out by providing assistance in the form of building evaporation houses and providing material assistance for repairing and building goat pens for salt farmers. The purpose of this activity is for salt farmers to increase their salt production capacity by increasing the speed and effectiveness of the production process. The method used is the construction method of a semi-elliptical evaporation house whose supports are made of elastic plastic pipes with iron reinforcements inside the pipe so that water vapor will flow through the pipes and plastic formed in a semi-elliptical construction. Community service activities were carried out by building an evaporation house for the salt production process. In addition, the community service team provided material assistance for the construction and repair of goat pens for salt farmers. Livestock farming for salt farmers is a common side business carried out by salt farmers to support household economic needs. The results of the activity were the construction of a semi-elliptical evaporation house that will be used by salt farmers to increase salt production and assistance to salt farmers in the form of material assistance for the construction and repair of salt farmer's livestock pens.
