Abstract
When conventionally laser-welding transparent materials such as glass, researchers often primarily focus on the material’s joint strength, paying scant attention to variations in optical transmittance within the welding zone. However, in fields like biomedical applications, optical characteristics are also pivotal in characterizing the efficacy of welding. Therefore, this study investigated the relationship between scanning frequency and optical transmittance during laser welding. The findings indicate that a laser single pulse energy of 14.73 μJ, a repetition frequency of 500 kHz, a scanning speed of 600 mm/s, and an optimal scanning frequency of 45 times yielded the highest optical transmittance in the welding area. This resulted in a 13% increase in transmittance compared to stacking two glass pieces.

Authors: Huang Lili , Zhong Qingyun 
Published: September 2024

Abstract
The optimal design of forging preforming is the key to improving forging quality and productivity. Taking an I-shaped forging as a research object, an approach to optimize two-dimensional preform shape is employed. The mathematical model of multi-objective optimization in forging forming simulation is established, and the forming load and die wear are used as the objective functions to optimize the design. Two forms of straight line and circular arc are designed for the shape of the deformation area of the preforming die. With the aid of the finite element simulation software, the process of preforming and finishing forging by using the preformed die with different design variables and different parameters is simulated. Simulation results show that the best optimization results can be achieved when the linear angle is 53.5° and the circular arc radius is 66 mm. After optimization, the load drops by about 36 percent by adopting the circular arc shape, and by about 76 percent by adopting the straight-line shape. The die wear depth decreases and the wear zones become more balanced after optimization. Numerical results prove that this approach is effective in designing the optimal preform shape in forging.

Published: September 2024

Abstract
Glass is an advanced material with a wide range of applications. Improving the quality of glass products supports and promotes various industries. This paper discusses the streaks affecting the quality of glass products and focuses on implementing optical homogeneity detection technology for glass. Based on the relationship between optical homogeneity and mechanical properties, this detection technology analyzes the causes of streaks in the production process of glass products and deduces the causes for the streak characteristics through the discussion of the working principle of the homogeneity detection technology, the detection device, the detection steps and the use of technology. In this study, visual inspection technology is introduced into the optical homogeneity inspection technology instead of the traditional manual inspection method, which can make the inspection results faster and more accurate and can find a quick and effective solution to the streaks.
Evaluating the potential of green hydrogen, ammonia and urea in Lao PDR energy transitions.

Published: September 2024

Abstract
We report the results of a systematic evaluation of the redeployment of surplus hydropower electricity to produce green hydrogen (H2), ammonia (NH3) and urea (CH4N2O) in Lao PDR. Participatory system mapping (PSM) workshops convened across multiple Lao PDR ministries revealed both direct and indirect opportunities and risks as probable consequences of green H2, NH3 and urea production. Participants debated and prioritized green urea fertilizer to replace “grey” imports; coal co-firing; and fuel cells as the products that contribute to the opportunities and manage the risks identified by the PSM process. Techno-economic modelling indicates the levelized cost of urea (US$467/tonne) is competitive with Thai imports, associated with opportunities for trading carbon offsets. Carbon credits were not sufficient to offset the additional co-firing costs of coal generation, and fuel cells are a likely future enterprise. A targeted capacity building and training program was a central pillar of a systems-based dissemination strategy to develop necessary technical and planning skills and community and awareness raising. The collated research results represent an integrated foundation to draft the Lao PDR National green H2 and NH3 road map and action plan, and a cross-sectoral revision of energy transition development plans.

Abstract
Looking beyond cooking energy provision in humanitarian response, interventions define the course of the internally displaced people’s (IDPs) livelihood. Energy transition in displacement settings often puts the bar high as the outputs are aimed to provide full use of low emission, healthy, clean cooking energy sources. By gathering data from protracted temporary settlements inhabited since 2012 by those affected by the Mount Sinabung eruption in Karo Regency, Indonesia, the purpose of this study is to look into how Internally Displaced Persons (IDPs) are switching to greener energy sources for cooking. A framework for determining energy choice at the household size was employed to depict the overview of energy use in cooking, taking into account the effects of the transition. The case of Sinabung displacement offered a perspective of the prolonged IDPs on humanitarian energy interventions and the national ecosystem toward clean energy behaviour. Even though Liquid Petroleum Gas (LPG) penetration is subsidized, a protracted displacement situation in Sinabung still reveals solid fuel dependencies. The LPG subsidy program, which was poorly planned, and the lack of readiness of IDPs to purchase and use new alternative cooking energy were the biggest obstacles to the overall transition process and caused the fuel stacking phenomenon to persist.
Enabling Sustainable Energy Communities in ASEAN: A Systematic Approach to P2P Energy Transactions on Matakus Island Using IoT and Blockchain
Authors: Brillian Tangka Emmanuel , Suwandi Albertus 
Published: September 2024

Abstract
This paper addresses the need for energy diversification and sustainable development in the ASEAN region by proposing a decentralized peer-to-peer (P2P) energy trading system. PowerChain, a peer-to-peer energy trading platform, is tailored as the designated medium for implementation. PowerChain harnesses the capabilities of blockchain technology and utilizes MQTT and HTTP protocols to ensure security, transparency, and user-IoT interaction. A case study was conducted on Matakus Island, a rural area in Indonesia with high solar power generation potential and a suitable demographic for the study. Currently reliant on diesel-based power generation, the island serves as an ideal location to evaluate the feasibility and benefits of transitioning to a RE-based P2P energy trading system. Based on simulations using 2 types of load and generation from peer providers, it was found that unused energy for type 1 was 815.9 kWh/year and for type 2 was 821.05 kWh/year. So the total unused energy from 10 peer providers on Matakus Island that can be transacted on the Powerchain platform is 1,636.95 kWh/year. This energy can meet the needs of Matakus Island for 93.7 days.In the platform simulation, three experiments were carried out, namely, single type transactions, multiple type transactions, and rejection of energy requests. From these three experiments, Powerchain was able to perform well, where the seller was successfully selected based on the closest distance, and if the closest selection could not be fulfilled, the seller would come from several nearby buyers. And when a selected peer is rejected, the existing algorithm can search for and select a replacement peer.The integrated approach presented in this study demonstrates the viability of using IoT and blockchain technologies to transform the energy market structure and accelerate the transition towards cleaner and more efficient energy systems in ASEAN.

Abstract
Indonesia aims to achieve a New & Renewable Energy mix of 23% by 2025, so it is necessary to have policies related to the use of complementary feedstocks in the biofuel development program in Indonesia. Used Cooking Oil (UCO) is a domestic waste with the potential to be utilized as a complementary feedstock due to its abundant availability and almost zero carbon emission. However, to assess the sustainability of UCO utilization, especially as a component blending for Bio-Marine Fuel Oil, it is necessary to identify UCO characteristics and quality of its product, called as UCOME, also the production cost impact. The 10,000 liters of UCO used as feed in the pilot-scale UCOME production came from the household sector and HoReCa (Hotels, Restaurants, and Cafes). It was found that UCO had water content and %FFA ranging from 1421.03 - 1666.74 ppm and 1.7 - 15.9%. Furthermore, the UCOME produced has characteristics that comply with the standard of Marine Fuel Oil (MFO) ISO 8217 and SNI 7182 and has a price in the range of Rp.17,000 - 18,000. The results revealed that the UCO has the potential to be a feedstock for producing UCOME as a blending component for Bio-Marine Fuel Oil.

Authors: Bansal Manasvi 
Published: September 2024

Abstract
Sustainability and decarbonization need to be a central component of economic development in the backdrop of climate change, mandates and stakeholder pressures. Climate-resilient infrastructure can significantly contribute to this sustainable and clean development. As energy lies at the heart of decarbonization, this study focuses on one of the critical infrastructures, power sector, and examines the climate-resilience readiness of select clean technologies in light of India’s decarbonization challenge. Battery Energy Storage System (BESS); offshore wind and green hydrogen are studied based on secondary data, incorporating an exploratory and descriptive research design, while using the logic of deduction. Research sets out the barriers faced by India’s power sector in climate-resiliency transition, identifies indicators for measuring climate-resilience and assesses select technologies for their climate-resilience readiness for India’s energy transition. Barriers fall under 5 key categories – technical, monetary, governance, data and social. Indicators for resilience measurement encompass themes of reliability, robustness and resourcefulness. Resilience assessment reveals that BESS, offshore wind and green hydrogen are climate-resilient technologies, albeit, not without gaps which demand policy interventions. Although climate-resilience readiness of clean energy technologies will be of significance, 4 levers of energy transition will hold equal value – policy and regulations, technology, sustainable financing and ESG considerations.

Published: September 2024

Abstract
Commercial buildings are essentially important energy consumers for national electricity grid provider as it’s owned by businesses owners that directly keep up the national gross domestic product (GDP). Soaring load demand from commercial buildings usually occurs within few hours on peak business hour. Electricity grid infrastructure designed to support maximum demand of the system but underutilize most of the time outside the peak session. Growing number of EV penetration in local market can serve as mobile energy storage for Vehicle to Building (V2B) energy integration thus enable peak load shaving to minimize maximum demand during peak period. This study presents a feasible methodology approach on determining the suitable V2B tariff on several peak load shaving scenarios to provide attractive return to building owner and discounted off-peak tariff to accommodate lower EV owner’s charging cost. By having the combination of attractive V2B and off-peak tariff that benefits both sides, subsequently increase EV penetration for V2B. It may also charm EV markets as it minimizes the total cost of EV ownership and reduce maximum demand from electricity grid. Hence it reduces the transportation CO2 emissions and contribution toward optimization of grid network electrical infrastructure of transmission and distribution systems design with lower maximum design system requirement.

Abstract
Climate change has become a worldwide concern, prompting Indonesia to take ambitious actions to reduce emissions and control rising temperatures. The rapid growth of the Refrigeration and Air Conditioning (RAC) industry in Indonesia has led to higher greenhouse gas emissions. To tackle these environmental challenges, Pertamina Plaju Refinery is manufacturing natural refrigerants, specifically Musicool (Propane) and Breezone (Propylene), providing sustainable replacements for R-22 and R-32. Pertamina Plaju Refinery has made several process modifications and optimizations to support the production of Musicool and Breezone in the Alkylation and Purification Units. These modifications involve optimizing operating conditions and implementing necessary infrastructure changes. In general, Pertamina’s natural refrigerants consume 20-30% less energy than halogen refrigerants while offering similar cooling capacity to R-22 and R-32. Propane and Propylene-based refrigerants have the lowest impact on global warming and are eco-friendly due to their easy degradation process. Musicool and Breezone, having an ODP of 0.0, with maximum GWP of 3.3, indicating minimal contribution to ozone depletion. Pertamina’s efforts to engage and reach potential customers on these natural refrigerants, involve collaborative efforts among various organizations, including with all District Office Plaju, South Sumatra.

Published: September 2024

Abstract
This study improvised the Electricity System Cascading Analysis (ESCA) into the Bus Energy Storage Cascading Analysis (BESCA) then the method is applied in the electric bus transportation system. The BESCA applies pinch analysis methods to determine the minimum energy storage based on the current bus timetable and charging system. The increased charging load can also be moved to a non-operational period using BESCA. The minimum battery capacity can be determined more easily using the BESCA approach, the results of which are displayed graphically in the graph. The method was then used to study the effect of charger rate and the bus schedule on the electric bus battery capacity. The bus system’s application of BESCA shows that an electric bus with a minimum power requirement of 57.48 kWh and a 72 kW charging pole is needed.
Building a robust international carbon crediting framework: insights from Indonesia’s Joint Crediting Mechanism
Authors: Hana Mahsunah Dima , Kencana Adjani Wulan 
Published: September 2024

Abstract
This research explores the Joint Crediting Mechanism (JCM) implementation and effectiveness in Indonesia, a program adopted by Japan for carbon emissions reduction and climate change mitigation. Using a quantitative case study methodology, we combine primary and secondary resources to gain insights into the mechanism’s impact on low-carbon development. Findings reveal challenges in government commitment to green energy promotion and financial losses in the solar power sector. Future agreements must consider past implementation and develop a clear framework for Internationally Transferred Mitigation Outcomes (ITMOs) to yield mutual benefits. The JCM has implemented 50 industrial projects in Indonesia, primarily in renewable energy and energy efficiency sectors. It stands out as a leading pilot mechanism under Article 6.2 of the Paris Agreement and has reached full implementation, involving the collaboration of host and partner countries in line with international standards. Various funding models support JCM projects, but while some achieve impressive emissions reductions, the overall impact on Indonesia’s emissions remains relatively modest, emphasizing the need for more comprehensive strategies at the national level. The paper also compares the JCM with other carbon crediting mechanisms, highlighting differences and similarities. Challenges in constructing international carbon crediting mechanisms in Indonesia are discussed, and lessons learned from the JCM are outlined, offering valuable insights for the development of a global carbon crediting framework.
