Abstract

This study focuses on the public building in Indonesia that has implemented an energy management system compliant with ISO 50001 standard. The main objectives of this study are to review the implementation of the energy management system in the building, highlighting the main aspect of the ISO cycle deployment and key lessons learned for further dissemination. We performed the study of the implementation of energy management in the building sector based on the ISO 50001 framework that aims to enhance an organization to pursue the continuous improvement of energy management with a systematic approach. Implementing the plan, do, check and act cycle of the ISO’s framework, it is found that the management keeps a strong commitment to continuous improvement. As part of the energy management system cycle, an Investment Grade Audit (IGA) was performed in 2018. Implementing the IGA recommendation, both passive and active designs have been applied in the Slamet Bratanata building. Active design strategies that have been implemented include building automation system utilization, chiller and lighting replacement and Energy Monitoring System (EMonS) application. Implemented passive designs include windows film installation and an efficient room redesigned for optimizing natural light. To implement the ISO 50001 Energy Management System in the building, the energy management team has also held various activities. It includes developing Standard Operating Procedures, appointing a Person in Charge on each floor, conducting capacity building and performing an energy efficiency campaign. It is estimated that the energy management system has succeeded in reducing energy consumption by 613.188 kWh (in 2018–2020) and the Energy Efficiency Index by 129.06 kWh/m2/year in 2020. Furthermore, management energy implementation also reduced greenhouse gas emissions by 539.60 tons of CO2 equivalent. This study provides a reference for energy management in another building for improving its energy performance.

Abstract

Having great potential, a mechanism that can leverage private involvement in energy efficiency deployment should be developed in emerging markets such as Indonesia. This study aimed to formulate an implementable financial innovative scheme for leveraging energy efficiency deployment in the country. Scrutinizing relevant studies and interviewing relevant stakeholders such as the Ministry of Finance, Ministry of Energy and the Financial Institution, we formulated a blended financial scheme for an energy efficiency project. Main stakeholders will include the scheme, including fund facilitator, trustee, custodian bank and energy user/energy service company. In our proposed scheme, Indonesia Environment Fund (IEF) is obtained the fund from the fund facilitator. IEF will act as a trustee that delivers funds for the Custodian Bank. The bank will disburse the fund to the feasible energy efficiency project or through an energy service company. In this scheme, since banks get lower interest rate funds from the trustee, they will disburse the fund to the customer with a lower interest rate than a commercial rate. Consumers utilize the fund for their energy efficiency projects. Utilizing a proposed scheme to an energy efficiency project case study, it is found that the proposed scheme potentially reduces the interest rate and leverages the project viability in a certain condition. Doing the sensitivity analysis by comparing interest rate and IRR (Internal Rate of Return) in several loan periods, we found that the shorter period of the loan and lower interest rate can improve projects feasibility. For instance, simulating a 5-year loan, it is found that reducing the interest rate from 12% to 7% could improve up to 2% IRR of the project case. Therefore, the scheme can catalyze private-sector investments mobilization for energy efficiency deployment in the country. Furthermore, it can support the country's energy security enhancement.

Abstract

Street lighting can be considered the main energy consumer and greenhouse gas emitter at Indonesia's city level. In addition, public street lighting systems throughout Indonesia still use inefficient technologies, resulting in a significant portion of a municipality’s operating expenditure. We conduct techno-economy analysis and formulate financing mechanisms to support energy efficiency improvements on street lighting systems. In doing so, a pilot case based on a survey in one of the provincial capitals in Kalimantan is performed. From the survey, it is found that around half of the street lighting systems in the observed city are unmetered, dominated by CFL (Compact Fluorescent Lamp) lamps. Efficiency through street lighting system improvement can be achieved through, among others, replacement with a highly efficient light-emitting diode (LED) lamp, power meters installation and the replacement of high-efficiency armatures. Our analysis shows that energy consumption reduction potential from street light system improvements can reach 69% from existing conditions. In the showcase, it can save 9,466,465 kWh, equal to energy costs of IDR 13,676,202,724 and a 7,667-ton emission reduction. From the analysis, we also delivered a financial scheme for the project that incorporated local government and special mission vehicles under the coordination of the Ministry of Finance. Having great potential, a financing support mechanism can become a reference to another local government with a limited budget constraint. These findings can also provide policymakers with important inputs while improving street lighting systems as a key service provided by local and municipal governments.

Abstract

In this study, graphene oxide (GO) was successfully synthesized using the modified Hummer method. GO was synthesized using natural raw materials from coconut shell waste. The synthesis sample was characterized using XRD, FTIR, and SEM EDX. The XRD results showed that there were 2 main peaks corresponding to the hkl 002 and 100 planes. The XRD results showed that the synthesis sample tended to form reduced graphene oxide compounds (rGO). The functional group of the FTIR results showed that the GO formed was not completely reduced to rGO which was indicated by the presence of C-H stretching at a wave number of 3065 cm-1. In addition, there were also two C=O peaks in the alkoxy and epoxy groups which were characteristic of GO. The sample's morphology from the SEM results showed a typical structure of GO, namely forming a thin layered sheet with a thickness of around 14.57 to 14.86 nm. The optical properties of GO were also investigated using UV Vis and the energy band gap value was obtained around 2.97 eV.

Abstract

Selecting an appropriate inventory management application is a challenge for business actors, especially SMEs, due to the variety of features, costs, and complexities offered. Manual selection is often carried out without a clear systematic approach and tends to be influenced by bias, resulting in suboptimal decisions. This study aims to integrate the Rank Order Centroid (ROC) and Additive Ratio Assessment (ARAS) approaches in developing a Decision Support System (DSS) to determine the best inventory management application. ROC is used to assign proportional weights to criteria based on priority ranking, while ARAS evaluates alternatives using these weights and relative utility values against the ideal solution. The developed system includes key features such as data management for criteria, alternatives, and values, as well as the ability to generate recommendations through alternative ranking. Based on a case study, the best alternative identified is Sortly: Inventory Simplified, with the highest utility score of 0.8627, followed by Housebook - Home Inventory (0.8528), inFlow Inventory (0.8336), and Inventory Stock Tracker (0.7056). Usability testing showed an average user acceptance rate of 91%, categorized as "Excellent". The main contribution of this research is the implementation of a practical and efficient combination of ROC and ARAS for selecting inventory management applications. The findings can be adopted by businesses to support more accurate and efficient decision-making.
