Abstract

Utilization of solar power can use a thermoelectric generator. Thermoelectric Generators work by taking advantage of temperature differences and the application of the Seebeck effect. This experimental study uses two prototypes of a perfect house with a roof made of zinc plate. One of the roofs of the house is covered with glass. Thermoelectrics are installed at the bottom of the roof of each house as many as 12 pieces and arranged in a series circuit. Data collection was carried out one day from 08.00 -15.59. The largest electrical voltage obtained occurred at 11.00 – 13.59 reaching 0.215 – 0.183 Volts in houses with glass-covered roofs and 0.654 – 0.527 Volts. The use of a layer of glass makes the roof temperature stable because the heat absorbed can be retained by the glass. As a result, the voltage generated in a house with a glazed roof is more stable than a house with a non-glazed roof. This research also proves that the difference in temperature affects the voltage generated by the thermoelectric. Pemanfaatan tenaga surya dapat menggunakan termoelektrik generator. Termoelektrik Generator bekerja dengan memanfaatkan perbedaan temperatur dan penerapan efek Seebeck. Penelitian eksperimen ini menggunakan dua prototipe rumah sempurna dengan atap dari seng plat. Salah satu atap rumah dilapisi dengan kaca. Termoelektrik dipasang pada bagian bawah atap masing-masing rumah sebanyak 12 buah dan disusun dengan rangkaian seri. Pengambilan data dilakukan satu hari dari pukul 08.00 -15.59. Tegangan listrik terbesar yang didapatkan terjadi pada pukul 11.00 – 13.59 mencapai 0,215 – 0,183 Volt pada rumah dengan atap dilapisi kaca dan 0,654 – 0,527 Volt. Penggunaan lapisan kaca membuat temperatur atap menjadi stabil karena panas yang diserap dapat ditahan oleh kaca. Akibatnya membuat tegangan yang dihasilkan pada rumah dengan atap dilapisi kaca lebih stabil. Dari penelitian ini juga membuktikan perbedaan temperatur mempengaruhi tegangan listrik yang dihasilkan oleh termoelektrik.

Abstract

The supply chain is one of the factors that are very influential in the production process in a company. In actual conditions, often in the production process, there are still many defective products that will be sent to buyers. Therefore, this study aims to propose a single-vendor single-buyer inventory model with consideration of the presence of defective products to minimize the total joint inventory cost. An iterative algorithm is used to obtain optimal values of the frequency of shipments and the cycle length resulting in a minimum total joint inventory cost. The results of the numerical examples and sensitivity analysis indicate that proposed integrated model gives a significant cost saving along with a high percentage of defective products. Supply chain atau rantai pasok merupakan salah satu faktor yang sangat berpengaruh dalam proses produksi di suatu perusahaan. Pada kondisi yang sebenarnya, seringkali pada proses produksi masih banyak ditemukan produk cacat yang nantinya akan terkirim kepada pembeli. Oleh karena itu, penelitian ini bertujuan untuk mengusulkan sebuah model persediaan produsen tunggal pembeli tunggal dengan pertimbangan adanya produk cacat guna meminimalkan total biaya persediaan gabungan. Algoritma iteratif digunakan untuk mendapatkan nilai optimal dari frekuensi pengiriman dan lama siklus dalam menghasilkan total biaya persediaan gabungan yang minimum. Hasil dari contoh numerik dan analisis sensivitas menunjukkan bahwa model terintegrasi yang diusulkan memberikan penghematan biaya yang cukup signifikan seiring dengan tingginya persentase produk cacat.
