Hal ini dibutuhkan agar PLTS yang kita pasang sanggup atau memiliki daya yang cukup untuk mensuplai beban yang kita inginkan. Hal ini seringkali tidak diperhatikan sehingga menyebabkan PLTS yang dipasang tidak sanggup mensuplai beban secara maksimal ataupun PLTS yang ada jauh lebih besar dibanding beban yang digunakan, hal ini menyebabkan kerugian karena mengingat harga dari PLTS juga relatif mahal. Untuk mempermudah kita juga dapat menggunakan software PVSyst untuk menentukan kapasitas solar cell yang dibutuhkan beban. Tingkat intensitas cahaya matahari pada lokasi penelitian menurut aplikasi PVSyst adalah sebesar 4.5 kWh/m2/hari. Beban total pada laboratorium fakultas teknik setiap harinya adalah sebesar 36 kWh/m2. Untuk membebani total beban yang ada pada laboratorium fakultas teknik UMSU maka diperlukan PLTS dengan kapasitas 13,44 kWp yang terdiri dari 40 Unit panel surya berkapasitas 280 wp dengan bateri 100 ah sebanyak 40 unit. Untuk merealisasikan PLTS yang telah direncanakan, dapat dipasang pada roof top laboratorium fakultas teknik.

Indonesia sebagai Negara yang sebagian besar wilayahnya berupa perairan tentunya memerlukan proses monitoring bawah air demi terjaganya ekosistem dan sumber daya perairan. Banyak daerah perairan Indonesia memiliki berbagai macam resiko yang dapat membahayakan penyelam seperti hewan buas, limbah beracun, keterbatasan oksigen dan sebagainya. Karena permasalahan tersebut, maka dibuatlah projek rancang bangun sistem dan mekanisme prototype underwater ROV (Remotely Operated Vehicle) berbasis Arduino. Pada penelitian ini telah dibuat sebuah alat berupa robot kapal selam dengan menggunakan 4 motor dc untuk melakukan 8 jenis pergerakan di bawah air dengan hasilnya yaitu ROV yang dapat melakukan semua pergerakan tersebut. Dengan menggunakan driver motor BTS7960, setiap motornya dapat dikendalikan arah putar dan kecepatannya. Robot ini memiliki tujuan yaitu mengambil data berupa suhu, tekanan, dan gambar di dalam air dengan kedalaman maksimal yaitu 3 meter. Pengambilan data suhu dan tekanan dilakukan dengan menggunakan sensor suhu DS18B20 dan ditampilkan pada display LCD16x2. Sedangkan pengambilan gambar atau video dilakukan menggunakan kamera CCTV yang disambungkan dengan laptop sebagai monitornya dengan hasil gambar yang ditangkap cukup jelas.","PeriodicalId":17743,"journal":{"name":"Jurnal Surya Teknika","volume":"428 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75884207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Wiyono Red Brick Small and Medium Enterprises are required to make the track distance shorter and material handling costs cheaper. The necessary data was collected by conducting interviews with business owners and making direct observations at the Wiyono Red Brick Small and Medium Enterprises. This study used the Computerized Relative Allocation of Facilities Techniques (CRAFT) method. The results of the analysis using the CRAFT method show that the proposed layout has an alternative OMH layout of Rp.1,464,676.5, while the initial layout is Rp. 2,831,368.1, resulting in a difference of Rp. 1,366,691.6. The total distance of the initial layout is 269,654 m, while the alternative distance is 139,493 m with a difference of 130,161 m. From the results of the comparison, it is found that the difference between the initial layout and the alternative layout is so large that it is necessary to apply the alternative layout to make production more optimal.","PeriodicalId":17743,"journal":{"name":"Jurnal Surya Teknika","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83364334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Investors invest in stocks and try to get maximum results, but many investors are still unsure about the risks involved in investing. To minimize risk, investors need to predict stock prices with an accurate method. Several methods that can be implemented to predict stock data include Multi-Layer Perceptron (MLP), Long Short-Term Memory (LSTM), and Gated Recurrent Unit (GRU). The research objective to be achieved in this study is to compare the performance of each algorithm in producing a more accurate stock price forecasting model by testing neurons (10, 20, 30) and epochs (50, 75, 100). The research was conducted on the stock price data of PT. Merdeka Copper Gold Tbk (MDKA) which is a mining sector share with the largest capitalization value. Tests on some of the algorithms above got the best results using 82% training data and 18% test data, namely the MLP model with 10 neurons and 100 epochs with a MAPE training data result of 2.325 and a MAPE test data of 2.014. Based on the test results, MLP can predict MDKA stock prices for the 2018-2022 period with good performance and a relatively small error rate, while tests using the LSTM and GRU methods still produce large errors. Thus, it can be concluded that MLP can predict stock prices with more accurate results.","PeriodicalId":17743,"journal":{"name":"Jurnal Surya Teknika","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90456939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
