Abstract

Virtual Reality (VR) atau realitas maya adalah sebuah cabang media interaktif yang terus berkembang. VR merupakan teknologi yang dapat membuat pengguna dapat berinteraksi dengan lingkungan dalam dunia maya yang disimulasikan oleh komputer. VR membuat pengguna merasa berada di dalam lingkungan tersebut. Dalam mengembangkan VR kita harus memiliki pengetahuan tentang teknologi sensing and tracking, stereoscopic display, multimodal interaksi dan recognition (contoh : metafora dan menu tiga dimensi, suara, dan gerakan), grafis komputer, simulasi fisika dan lainya. Dengan teknologi-teknologi tersebut, VR dapat memanipulasi otak penggunanya seakan-akan berada pada dunia lain. Karena membutuhkan tingkat grafis visual yang tinggi untuk memberikan pengalaman yang realistis, salah satu tantangan utama dalam mengembangkan aplikasi permainan VR adalah latensi yang tinggi. Latensi yang tinggi mengakibatkan menurunnya kualitas pengalaman pengguna, karena ada waktu tunda antara aksi dari pengguna dan respon pada aplikasi. Latensi dalam penggunaan VR bahkan dapat menyebabkan sensasi mabuk. Penelitian ini bertujuan mengembangkan aplikasi VR dengan latensi rendah dengan studi kasus aplikasi permainan untuk anak dengan Autism Spectrum Disorder (ASD) dengan tetap mempertahankan kualitas grafik visual yang baik. Pada penelitian ini, nilai latensi per komponen kualitas visual dan nilai kualitas performa aplikasi diukur menggunakan tools profiler dari Unity. Hasil pengujian menunjukkan bahwa penurunan nilai masing-masing komponen visual sepertianti-aliasing, shadow resolution, cascades dan soft shadow dapat mengurangi latensi. Diantara komponen visual tersebut, anti-aliasing yang berkontribusi paling besar terhadap latensi. Penelitian ini berhasil mendapatkan kombinasi optimum diantara komponen-komponen visual tersebut untuk mendapatkan latensi yang rendah dan grafik visual yang baik.

Abstract

This paper proposes a fully convolutional variational autoencoder (VAE) for features extraction from a large-scale dataset of fire images. The dataset will be used to train the deep learning algorithm to detect fire and smoke. The features extraction is used to tackle the curse of dimensionality, which is the common issue in training deep learning with huge datasets. Features extraction aims to reduce the dimension of the dataset significantly without losing too much essential information. Variational autoencoders (VAEs) are powerfull generative model, which can be used for dimension reduction. VAEs work better than any other methods available for this purpose because they can explore variations on the data in a specific direction.

Abstract

As a commitment for service improvement, Pertamina provides self-service gas station to reduce queue time and various non-cash payment methods such as debit and credit cards in cooperation with various banks, or subscription cards such as Gazcard which is issued by Pertamina. Nonetheless, these two services have not been integrated. Cashless payment is only available at conventional gas stations. This research proposes a new payment method for self-service stations using digital-wallet, a mobile-based applications, which will overcome the limitations of the existing payment methods at self-service gas station in terms of the guarantee payment for each transaction even when there is no operators around and the flexibility of payment in accordance with the volume of gasoline pumped out from dispenser. In addition, some modifications are also made toward the dispenser so that the dispenser is able to read the customer ID and communicate with the backend system of the mobile application. Implementation of this prototype is expected to improve service at SPBU by reducing queue time, improve company efficiency by reducing the number of operators in gas station. Furthermore, mobile applications can be utilized as communication channel with customers in order to improve customer engagement. In the long run, data obtained from recorded transactions can be used for various analyzes such as customer needs identification, loyalty program analysis, and provide additional services based on pattern captured from the data.

Abstract

Air Conditioning is one of the most energy-consuming infrastructure in a building, which makes it one of the things that an asset manager needs to pay special attention to. This research uses comparative method that compares the current AC usage scenario in Universitas Pertamina’s Griya Legita Building, which currently uses both split AC and cassette AC, with a scenario where the whole building only uses either split AC or cassette AC. The calculation shows that, although the first-year investment for new AC installation costs more than the current scenario, the scenario where the whole building uses only split AC is proven to be a more cost-efficient investment in the long run. The result of this research is an important asset for the asset manager of Universitas Pertamina to consider in order to save energy consumption cost in Universitas Pertamina.

Abstract

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.
