Adding Psychological Factor in the Model of Electricity Consumption in Office Building Meredita Susanty
International Journal of Electrical and Computer Engineering (IJECE) Vol 8, No 6: December 2018
Publisher : Institute of Advanced Engineering and Science

Researches indicate that energy behaviour is the key to energy conservation and suggest that comparative feedback on energy usage can generate savings in residential and organizational settings. In implementing comparative feedback in workplace, there are two different ways to disaggregate collective energy consumption and apportion it to building users; individual or group level. This research uses agent-based modelling and simulation to examine the impact of applying different approaches of energy data apportionment to change staff behaviour toward energy consumption reduction. A simulation model of energy consumption in workplace as a base model is a re-implementation and simplification from former research. Several psychological factors and decision-making mechanism are then being added as an extension. The model divides staffs into four energy awareness stereotypes based on motivation level. Sensitivity analysis suggests that motivation is an important factor in changing user‟s behaviour and the experiment results indicates greater potential for energy saving when energy usage is apportioned to group level. The significant difference of energy consumption level makes user with low and medium motivation should become the target of energy reduction campaign.

Kesehatan mata harus terjaga dengan baik karena peran kedua mata sangat penting bagi kehidupan manusia. Namun tahun 2012 Indonesia memiliki angka gangguan penglihatan yang cukup tinggi sebesar 1,5% dari seluruh penduduk indonesia atau sekitar 3,6 juta jiwa. Pemerintah Indonesia telah menyiapkan sarana dan prasarana pelayanan kesehatan yang baik di puskesmas maupun rumah sakit. Sayangnya, kesadaran masyarakay untuk datang dan memeriksakan matanya di fasilitas kesehatan yang telah ditentukan masih rendah. Meningkatnya pengguna internet dan mobile phone mendorong perkembangan teknologi dan memunculkan inovasi - invasi baru. Salah satunya adalah Aplikasi Mataku, sebuah aplikasi berbasis Android yang membantu untuk melakukan pengecekan dini terhadap berbagai penyakit mata seperti penyakit katarak, pterigium, buta warna, dan miopi. Melalui aplikasi ini ini pengguna juga dapat berkonsultasi dengan dokter spesialis matasecara daring. Untuk menjamin aplikasi dapat dengan mudah digunakan oleh pengguna, perlu dilakukan pengujian usability dengan parameter learnability, efficiency, memorability, errors dan satisfaction. Pengujian ini menggunkan metode usability testing terhadap purwarupa aplikasi. Hasil pengujian ini menunjukkan adanya permasalahan pada salah satu fitur pada aplikasi.

Indonesian government set the target for new and renewable energy (NRE) is expected to be 23% in 2025 and 31% in 2050, where in 2017, NRE was only 12,5%. Building a new and renewable energy project is the easy part. Keeping the generator working over time, however, is a complex business that requires money, training and innovative thinking. One of essential parameters that can help in achieving a successful sustainable project is community involvement. If the community feels a strong sense of ownership, they'll see their generator as a critical asset to everyone and take good care of it collectively. Training and educating the community about how to take care of the generator after the project construction has completed becomes important. Considering Indonesia’s geographical location, e-learning might be a potential tool to reduce training and education cost in new and renewable project. This study aims to identify whether e-learning is an effective and efficient method to deliver training material and educate local people which will improve renewable energy project’s sustainability in Indonesia.

One of the stages in oil and gas exploration is a Petrophysical analysis, which aims to determine the structure of rock layers below the earth's surface. The petrophysical analysis uses physical properties in a well-log to determine the rock type below the surface. Nowadays, the software for conducting petrophysical analysis has utilized a machine-learning approach to predict rock types. Most of the software uses the supervised learning method to classify rock types. This research uses a different approach, unsupervised learning, to group rock types based on various features in a well-log. Using a publicly available well-log in Stafford, United States, and the k-means clustering algorithm, this study groups the data into 3 clusters. The result is compared with manual analysis interpretation and shows an alignment between them. From the result, it shows that the unsupervised learning method effectively predicts limestone, shale, and evaporites in the well. It classifies the dataset into useful clusters, generates useful lithologies, provides useful rock characterization, and less time-consuming.

Pore pressure is a critical parameter in designing drilling operations. Inaccurate pore pressure data can cause problems, even incidents in drilling operations. Pore pressure data can be obtained from direct measurement methods or estimated using indirect measurement methods such as empirical models. In the oil and gas industry, most of the time, direct measurement is only taken in certain depth due to relatively high costs. Hence, empirical models are commonly used to fill in the gap. However, most of the empirical models highly depend on specific basins or types of formation. Furthermore, to predict pore pressure using empirical models accurately requires a good understanding in determining Normal Compaction Trendline. This proposed approach aims to find a more straightforward yet accurate method to predict pore pressure. Using Artificial Neural Network Model as an alternative method for pore pressure prediction based on logging data such as gamma-ray, density, and sonic log, the result shows a promising accuracy.

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.

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.

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 Paper is made of wood which comes from tree trunks and is a medium that can be used for promotional activities. However, the relatively high use of paper in Indonesia causes the forest area in Indonesia to decrease every year. One of the contributors to the largest use of paper is education, for example universities. The use of paper in universities can be found during university promotion activities. This study makes a comparison between promotional activities that are carried out using paper and those using digital technology such as social media. In addition, this study was conducted to determine how efficient the university's promotional activities were using paper and social media (paperless). The method used in this research is literature review and data observation at Pertamina University. The result of this research is that the use of social media as a promotional activity for universities is cheaper and more environmentally friendly than paper. ABSTRAK Kertas terbuat dari kayu yang berasal dari batang pohon dan merupakan salah satu media yang dapat digunakan untuk kegiatan promosi. Namun, penggunaan kertas di Indonesia yang terbilang tinggi menyebabkan luas hutan di Indonesia menjadi berkurang setiap tahunnya. Salah satu penyumbang penggunaan kertas terbanyak adalah bidang pendidikan contohnya universitas. Penggunaan kertas di universitas dapat ditemukan pada saat kegiatan promosi universitas. Penelitian ini melakukan perbandingan jika kegiatan promosi dilakukan dengan menggunakan kertas dan dengan teknologi digital seperti media sosial. Selain itu, penelitian ini dilakukan untuk mengetahui seberapa efisien kegiatan promosi universitas jika menggunakan kertas maupun media sosial (tanpa kertas). Metode yang digunakan pada penelitian ini yaitu kajian pustaka dan observasi data di Universita Pertamina. Hasil dari penelitian ini adalah penggunaan media sosial sebagai kegiatan promosi universitas lebih murah dan ramah lingkungan dibanding kertas.
