Abstract

Pada artikel ini akan dibahas analisis perbandingan konsumsi listrik dari penggunaan lampu secara manual dan lampu secara terjadwal otomatis. Penggunaan lampu secara manual ialah lampu dinyalakan dan dimatikan menggunakan saklar tanpa adanya batasan waktu, sedangkan penggunaan lampu secara terjadwal otomatis ialah penggunaan lampu yang hanya akan menyala dan mati sesuai dengan jadwal penggunaan ruangan yang terdaftar. Adapun tujuan dari dibuatnya artikel ini adalah untuk mengetahui kelayakan dari metode penggunaan lampu secara terjadwal otomatis dengan menganalisis apakah penggunaan lampu dengan metode tersebut dapat mengurangi konsumsi listrik atau tidak. Metode yang kami gunakan adalah perbandingan kuantitatif, dengan mengumpulkan data yang diperlukan untuk mendapatkan pengeluaran energi listrik untuk penerangan di gedung Griya Legita, kami membandingkan pengeluaran energi listrik ketika penggunaan lampu tidak terjadwal dan ketika penggunaan lampu dibuat terjadwal dengan sistem otomatis sepanjang Januari 2018. Hasil menunjukkan sistem lampu secara terjadwal otomatis memberikan efisiensi bekisar antara 1,5% hingga 94%. Pada bagian akhir dari artikel ini disimpulkan bahwa penggunaan lampu secara terjadwal otomatis dapat mengurangi konsumsi daya listrik di Gedung Griya Legita Universitas Pertamina meski tidak signifikan dikarenakan beberapa asumsi.

Abstract

To embrace the cashless future, PT PERTAMINA collaborate with various banks and LinkAja!, one of e-finance services in Indonesia, to accept cashless payment using QR code technology using mobile application. The cashless payment now accepted in both conventional gas station and self-service gas station. However, at a self-service gas station, customers generally make payments before refueling to an operator located in the control post (before the dispenser area/refueling area). It requires the customer to return to the operator in order to request the change when they stop refueling before reaching the requested volume. This research proposes some modifications toward the fuel dispenser so that the dispenser is able to accept cashless payment, provide correct amount of fuel, and guarantee payment for each transaction even when there are no operators around. The implementation of this prototype improves service at gas station by reducing queue time about three to seven second per vehicle, improve company efficiency by reducing the number of operators in gas station from one operator per dispenser to one operator per station, also, it removes the balancing process performed by the operator at the end of the shift. Sales reports are generated automatically in near real-time.

Abstract

The distinctive shortage in the availability of skilled labor in new and renewable energy sector becomes the issue that has been prevented this country in achieving the national energy mix in 2015 and 2050. Although both formal and non-formal education initiatives already exist to foster new and renewable energy education, the number of graduates cannot outpace the number of required labor. The number of graduates and their competencies must be considered because local labors are facing intense competition with foreign labors due to ASEAN Economic Community policy. This research aims to find a solution to address the educational issue in new and renewable energy education. This research is using iterative methodology from the software engineering domain to identify issues and problems in new and renewable energy education in Indonesia and suggested alternatives to address it. Combination of techniques (questionnaire, interview, studying documentation, and research a similar product) is used in requirement elicitation stage in order to provide multiple perspectives.

Abstract

Perkembangan bidang industri pencahayaan menjadi salah satu hal yang banyak mendapat perhatian oleh para peneliti dan investor khususnya dalam usaha penghematan energi, usia pemakaian, dan kelestarian lingkungan. Salah satu penemuan baru dibidang industri pencahayaan adalah teknologi Light Emitting Diode (LED). Teknologi LED mempunyai keunggulan dalam penghematan energi. Lampu LED memiliki watt yang jauh lebih kecil dengan tingkat penerangan yang lebih tinggi dibandingkan lampu fluorescent dengan besar watt yang sama sehingga teknologi LED mulai menggeser teknologi Fluorescent sebagai teknologi yang digunakan oleh sebagian besar komoditas sebelum munculnya LED. Hanya saja harga lampu LED lebih mahal sehingga membentuk pemikiran beberapa orang bahwa penggunaan LED belum tentu lebih hemat dari segi dana. Tulisan ini bertujuan untuk membandingkan pengeluaran dari penggunaan lampu LED dan fluorescent dan mencari tahu penggunaan teknologi pencahayaan yang lebih efisien untuk Gedung Griya Legita. Hasil penelitian menunjukkan bahwa dalam jangka waktu yang lama, penggunaan lampu LED lebih efisien dibandingkan dengan penggunaan lampu fluorescent.

Abstract

Attendance recording with RFID tags scan, make human resource (HR) staff’s task more effective and efficient because it is saving time and effort in performing manual recording and recapitulation that must be performed by the HR staff in a company. However, the number of cases where employees forget to bring their identification cards, which has an RFID tag increases the workload of human resource staff. This study proposes a facial recognition prototype as an alternative way to record employee attendance. The model used in this study uses artificial neural networks that have more than one hidden layer and uses a supervised learning approach. The results of the study show that when a high-resolution image provided for the training data, the prototype able to make an accurate prediction. However, some further study is needed before replacing existing attendance recordings with face recognition to address several problems such as distance between camera and object and accessories that affect the essential features in a face like glasses, headscarves, and mask. Further research should find the maximum distance between the object(s) and the camera and the position (angle) of the object towards the camera.

Abstract

Untuk mencapai target konservasi energi sebesar 17% di tahun 2025 pemerintah menerapkan aturan management energi bagi industri/penguna energi lebih besar sama dengan 6000 TOE. Di sektor bangunan gedung di Indonesia, konsumsi energi terbesar adalah penggunaan pendingin udara. Salah satu cara untuk melakukan penghematan dalam tata udara dengan menggunakan perangkat yang hemat listrik tanpa mengorbankan kenyamanan penghuni gedung. Penelitian ini menggunakan metode jaringan saraf tiruan untuk memprediksi beban pendingin optimum untuk suatu gedung berdasarkan 8 karakteristik bangunan. Model yang dibuat memberikan hasil yang baik dengan nilai nilai loss 0,4-1,1%

Abstract

Starting in 2019, prospective college students require to take Computer-Based Writing Exam (UTBK) to register for the state universities in Indonesia. Some private university also adopts this exam as a requirement for admission. One of the private university that adopts it is Universitas Pertamina. UTBK consist of several exam group score printed in a digital certificate in image format (jpg). The university admission team must download the UTBK certificate that has uploaded by applicants, read and record the score for each exam group then make a calculation to make a decision whether the applicant is accepted in a certain school in the university. This research proposes to replace the manual process performed by the admission team with optical character recognition (OCR). The OCR engine will extract text from an image. Some information from the extracted text is calculated to provide an acceptance decision. The research shows that OCR cannot accurately convert text from an image when there is a grayscale background in the image. However, image preprocessing can improve overall accuracy. Lastly, Tesseract performs better in converting black text with white-background than white text with a black background.
