Abstract

Lecturer Building is a facility that has full of activity and full of people inside from morning until afternoon. The Lecturer Building use in this research has a big problem with electricity utility which the energy source of the building until now still using limited fossil energy in its use. Another problem with the façade building was facing the sun in the morning. Then the temperature building was increasing and make uncomfortable conditions inside. Window integrated Solar PV or solar façade not only reducing incoming solar radiation but generate electricity.

Abstract

Observatorium Astronomi ITERA Lampung (OAIL) merupakan salah satu obseravatorium terbesar di Asia Tenggara yang dibangun di Provinsi Lampung. Lokasi pembangunan OAIL berada pada daerah remote area yang sulit terjangkau. Remote area tersebut memerlukan penyediaan energi listrik yang dapat memberikan jaminana keberlanjutan kegiatan astoronomi. Penyediaan energi listrik melalui PLN tidak terjangkau pada daerah tersebut. Energi terbarukan berupa PV dengan sumber energi matahari dapat menjadi solusi. Energi matahari dapat menghasilkan listrik dan memenuhi kebutuhan dengan berbagai aspek ekonomi teknik dan keandalan Dari hasil penelitian ini didapatkan bauran energi terbarukan untuk penyediaan energi adalah 10%

Abstract

Provinsi Lampung memiliki garis pantai yang cukup panjang yaitu sekitar 81.000 km. Namun,pasokan air bersih di wilayah pesisir pantai sangatlah terbatas terutama pada daerah-daerah yang padat penduduk.Pengabdian kepada masyarakat ini bertujuan untuk mengatasi permasalahan air bersih di daerah pesisir masyarakat Desa Rangai Tri Tunggal, Lampung Selatan.Metode penentuan perumusan masalah dilakukan dengan metode observasi dan wawancara warga di Desa Rangai Tri Tunggal, Lampung Selatan.Pada pengabdian kepada masyarakat ini, kami membuat alat destilasi air laut untuk memperoleh air tawar berupa alat reflektor cermin cekungyang memanfaatkanpanas energi matahari.Reflektor cermin cekung memiliki diameter 1,8 meter, tinggi cermin 0,4m dan titik fokusnya 0,45m. Reflektor cermin cekung diletakkan di atas tanah dan disinari langsung matahari. Kolektor yang berisi sampel air laut diletakkan diatas reflektor tepat pada posisi titik fokus untuk melakukan proses destilasi. Waktu pengamatan penggunaan reflektor cermin dilakukan selama 7 hari pada cuaca cerah dan dimulai pukul 8 pagi hingga 4 sore. Dari pengamatan yang dilakukan dihasilkan temperatur maksimum suhu destilasi air laut yang didapat menggunakan reflektor cermin cekung adalah 79,4˚C dengan hasil destilasi air tawar diperoleh rata - rata sebesar 508 ml dari volume awal air laut sebesar 2 liter.

Abstract

In this paper, design of solar energy harvesting system which integrated in building glass window was proposed. The location as the design reference is Bandar Lampung Building. Bandar Lampung Building uses 90% of the glass on the outside walls building with facing the sunrise and sunset. The design solar energy harvesting system was consisted of solar glass and electronic power system. Solar glass using several mini PV affixed on the glass with space in between, so partially of sunlight pass into the room. The solar energy harvesting system used for DC house network and not connected to the grid system. The solar energy harvesting is also equipped with power electronic system such as MPPT, lead acid battery, and DC-DC converter. The design of solar energy harvesting system is using calculative method based on secondary data several references for this case. Area of the solar glass reaches 16.32 m2 for 1 office room scale. The ratio between PV and room glass about 0.35. The power average of the solar glass on the glass building with facing to the sunrise is about 74.35 W, and then the average power of the solar glass with facing to the sunlight about 161.32W.

Abstract

In this era, energy demand is increasing along with population growth and technological development. Energy is a basic need, and its availability is decreasing, necessitating renewable energy sources like solar energy. However, the current use of solar Photovoltaic (PV) relies only on one side. In this study, the bifacial method is used in solar power plants (PLTS) to reduce conventional energy consumption by identifying the relationship between the tilt angle and internal shading that affects the performance of bifacial photovoltaics. The PLTS system is designed with inclination angles of 8, 15, and 20 to minimize shading and maximize efficiency. PVsyst simulation results show that an 8 angle produces 22868 kWh/year, a 15 angle produces 22724 kWh/year, and a 20 angle produces 22464 kWh/year. Shading affects energy production, but the 8 angle has the lowest power reduction. Choosing the right inclination angle can improve PLTS efficiency and performance.
