BUSINESS MODEL INNOVATION OF OFF GRID PUBLIC ELECTRIC VEHICLES BATTERY SWAP STATION WITH SOLAR POWERED Tubagus Alviannanda, Vita Lystianingrum Budiharto Putri PLN, ITS Abstract Energy transition is Indonesia^s national agenda in order to maintain energy security and realize the use of green energy. The use of electric vehicles (EVs) is one strategy to maintain primary energy security and support the reduction of carbon emissions. In an effort to support the growth of the EVs ecosystem, Public Electric Vehicle Battery Swap Stations (Stasiun Penukaran Baterai Kendaraan Listrik Umum, SPBKLU) have been developed and installed in several locations. Currently, SPBKLU still uses electricity sources from the PLN (Perusahaan Listrik Negara, Indonesia electricity state-owned company) grid, where the majority of the PLN grid itself still relies on gas and coal power plants. Hence, this work proposed a PV-powered battery swap station and present the financial and SWOT analysis. Two business model schemes are proposed, namely the BPCOSO (Battery Provider, Cabinet Owner, Solar PV Owner) and BPCOSL (Battery Provider, Cabinet Owner, Solar PV Lease) schemes. From these two business schemes, the results of the financial feasibility analysis for the SPBKLU swap rate were obtained at IDR 18,241 for the BPCOSO scheme and IDR 21,500 for the BPCOSL scheme. From a SWOT analysis perspective, the BPCOSO and BPCOSL business schemes have the opportunity to increase the Solar PV business value chain and support government programs in achieving Net Zero Emissions. However, there are still weaknesses in terms of tariffs which are still not economical when compared to the fuel costs of conventional two-wheeled vehicles and the current SPBKLU swap tariff which still uses electricity from the PLN grid.

The focus of research is the use of banana peels as activated carbon to reduce vehicle exhaust emissions in the hope of providing environmentally friendly alternative solutions to reduce air pollution, utilising the adsorption properties of banana peels, and using biogasoline to overcome potential fuel crises. The experimental method was used to test the effect of an activated carbon catalytic converter made from banana peel with biogasoline fuel on motorcycle exhaust emissions. The test results showed that the use of catalytic converters with biogasoline fuel tended to reduce carbon monoxide (CO) levels by an average of 18%, compared to standard conditions with pertalite fuel. The results of the Paired Samples T-Test showed a strong correlation with a value of 0.967 and a significance level of 0.033, where a small value of 0.05 means statistically significant.

Universitas Trisakti, Faculty of Industrial Technology, Department of Industrial Engineering, 11440, Kyai Tapa No 1, West Jakarta, Indonesia 2. Faculty of Manufacturing and Mechatronic Engineering Technology, Universiti Malaysia Pahang Al-Sultan Abdullah, 26600 Pekan, Pahang, Malaysia Abstract Company X is an Indonesian shoe manufacturing company that collaborates with sports apparel from Germany as a manufacturer in the Partner supply chain. The material procurement, subcontractor, production, and storage take a long time in the product supply chain because the lead time is longer than the specified lead time, resulting in delays in shoe products and product quality problems. Moreover, it becomes waste that has a destructive impact on the supply chain. In the chain process, some effects impact environmental conditions due to the rest of the production process, and products rejected become waste. This research aimed to overcome this issue using the Sustainable Lean Supply Chain approach to improve economic gain, social security, and environmental quality. First, determine the cause of the problem using a fishbone diagram and Sustainable-Value Stream Mapping (SVSM) to map the supply chain flow of the current condition (inbound, operation, and outbound). The results of SVSM were analyzed using Process Activity Mapping tools to group activities according to the division of activity types, namely non-value-added, necessary non-value-added, and value-added. The Sustainability Index (SI) calculation uses indicators based on economic, social, and environmental pillars. The results of the SVSM mapping of the production operation process obtained a process cycle efficiency (PCE) of 62.34% and a manufacturing lead time (MLT) of 624,874.01 seconds with conditions after repair of 68.26% and MLT of 570,736.29 seconds. The SI for inbound improvement is 111.02%, the operation process is 86.01%, and outbound activity is 184.33%. The results of this research can guide practitioners in implementing a lean supply chain competitive strategy to enhance the SI. The research provides empirical evidence of the positive relationship between a sustainable lean supply chain and sustainable performance for academicians.

Multi-Angle Facial Recognition: Enhancing Biometric Security with a Broadly Positioned Stereo-Camera System Muhamad Amirul Haq(a*), Le Nam Quoc Huy(b), Muhammad Ridlwan(c), Ishmatun Naila(d) (a) Department of Computer Science, Faculty of Engineering, Universitas Muhammadiyah Surabaya, Surabaya, Indonesia * amirulhaq[at]ft.um-surabaya.ac.id (b) Department of Mechanical Engineering, College of Engineering, National Taiwan University of Science and Technology, Taipei City, Taiwan (c) Department of Indonesian Language and Literature, Faculty of Teacher Training and Education, Universitas Muhammadiyah Surabaya, Surabaya, Indonesia, (d) Primary School Education Program, Faculty of Teacher Training and Education, Universitas Muhammadiyah Surabaya, Surabaya, Indonesia Abstract This study addresses the vulnerabilities of traditional monocular camera-based face recognition systems, emphasizing the need for improved security and reliability in biometric authentication under varying conditions and human poses. To counteract the risk of spoofing attacks using masks or static images, we introduce a multi-angle stereo camera system. This system is strategically designed to capture facial imagery from multiple perspectives, thereby enhancing depth perception and spatial accuracy, crucial for high-security authentication. Employing a novel image processing approach, the study integrates a hybrid model of Convolutional Neural Networks and Transformers. This combination exploits CNN^s robust feature extraction capabilities with the Transformers^ generalization prowess, enabling precise detection and analysis of 3D facial landmarks. Such an approach significantly bolsters the system^s ability to differentiate between genuine faces and deceptive representations like masks or static images. Empirical results demonstrate that the stereo camera configuration substantially improves recognition accuracy, reducing both false positives and negatives, especially in controlled spoofing scenarios. The advanced 3D facial landmark detection further reinforces the system^s security. With its enhanced robustness and security, the developed system shows great potential for applications in areas requiring stringent identity verification, such as banking, public facilities, and smart home technologies.
