Abstract

In the modern era, it will be very difficult for humans to carry out activities without the presence of electrical energy. This is due to the fact that most of the current human needs are based on the use of electronic instruments and machines that require electrical power as their main source of energy. In addition, the availability of electricity is one of the important parameters for the progress, growth and development of an area in the economic, industrial, public service, commercial sectors and even improve the quality of life of it’s people. So that electrical energy planning is needed to overcome and provide solutions to electrical energy problems. This research uses LEAP (Long-Range Energy Alternative Planning Systems) software with the DKL 3.2 approach model to calculate the projected electricity supply needs in Papua province in 2018-2038. From the calculation results of the projection using the DKL 3.2 method for the needs and customers of electricity in 2018-2038, the demand for electricity in the household, industrial, business, and public sectors grew by 12.66%, 16.43%, 5.87 % and 9.78%. As for the projected number of electricity customers in the same sector, customer growth was 6.42%, 4.50%, 3.40% and 6.42%. The results of this study indicate an increase in energy demand in all customer sectors. Keywords : projection, electrical energy, DKL 3.2 metdod, LEAP

Abstract

Air kerap menjadi masalah dalam dunia pertambangan di Indonesia yang memiliki curah hujan yang cukup tinggi karena dilalui garis khatulistiwa, curah hujan yang cukup tinggi ini dapat menyebabkan tergnggunya aktivitas penambangan. Berdasarkan data Kementrian Energi Sumber Daya Mineral (ESDM, 2018) terdapat 8588 perusahaan yang telah memiliki Izin Usaha Pertambangan (IUP) dengan 6390 perusahaan yang telah memiliki IUP Clean and Clear dan 2.198 perusahaan yang memiliki IUP non Clean and Clear. Apabila semua perusahaan yang telah mendapatkan IUP CnC dan rata-rata debit air limpasan minimum yang diambil dari beberapa perusahaan tambang di Indonesia adalah sebesar 1,54 /detik, maka dapat dihitung potensi jumlah air buangan tambang pada area IUP CnC dan potensi energti listrik yang dihasilkan melalui teknologi mikrohidro. Penerapan teknologi ini dapat dilakukan dengan merancang sistem aliran untuk menentukan jumlah serta ketinggaian aliran pada teknologi mikrohidro. Berdasarkan rancangan dan debit rata-rata yang didapat, maka dapat diperkirakan bahwa potensi energi listrik yang dapat dihasilkan melalui pendekatan analisis adalah sebesar 246,8 MW. Nilai potensi energy listrik sebesar ini dapat dimanfaatkan untuk kebutuhan listrik yang lainnya sehingga dapat memungkinkan tercapaikan rasio elektrifikasi tahun 2019.

Abstract

The development of electronic technology, especially in the industrial world plays an important role in the production process. Currently there are many machines that calculate the number of manufactured goods. But the counting machine is only able to count the number of items without storing the large number of items that have been produced and there are still those that are not equipped with a monitoring system. Workers must make a report for the amount of goods that have been produced. This can affect the production process which will grow longer and is also very dependent on the limitations of human labor. Conveyor system design uses Raspberry pi model B and Arduino as a control system and HMI. The Optocoupler sensor is used to calculate the number of rotations when the conveyor drive dc motor has started operating. The data obtained will then be displayed on the LCD touchscreen by Raspberry Pi and will also be sent to the server so that it can be monitored online. Besides being displayed, the user can control the speed of the conveyor and also provide setpoints for goods count. The results of this study are the Conveyor System which can be monitored online or offline. Motor speed regulation can also be done by giving pwm to enable motor driver pin. The reading of the motor RPM by using the optocoupler also has very little error, at 4.1%.

Abstract

The fingerprint-based biometric system is one of the safety standard in office and used to check employee attendancee. The method that commonly used in fingerprints detection, is image extraction from fingerprint sensor acquisition. The image extraction will produce a special feature which is called minutiae. Each person has a specific minutiae that can be used as a basis for fingerprint detection. First step regarding to fingerprint detection is to convert the image into binary thus thinning image method can be implemeted to obtain skeleton image. After image thinning is applied, extraction minutiae is following by ridge bifurcation and ridge ending identification on the image. This research merely uses two types of minutiae. The next step in the extraction feature is image matching to test the similarity between the image from the data test and database. Euclidean distance is used to test the similarity both of images and thresholding method is to determine the degree of similarity. This study enhances the method by adding average Euclidean distance formulation, which considers the value from all similar fingerprints database. In order to test the result of the proposed method, the DB1 international standard data set are used which consist of 80 types of fingerprints from 10 different people. The result shows that the method applied has an accuracy of 81.25% which means that the method can be used as an algorithm to solve fingerprint detection problem..
