Published: December 2024

Abstract
One of the biggest challenges in sustainable development is how to optimally utilize natural resources without damaging the ecosystem functions that support human life and other living things. Natural resources such as water, land, forests, minerals, and energy are important assets that must be preserved so that they can be utilised fairly and responsibly by current and future generations. For this reason, strategies and policies are needed that can integrate economic, social and environmental aspects of natural resource management. Environmental law studies are studies that examine legal aspects related to environmental protection and management. The purpose of this study is to determine the extent to which environmental law can provide a normative basis for the sustainable use of natural resources. This research is a normative juridical research using data analysis in the form of qualitative juridical analysis. The utilisation of natural resources must pay attention to the needs of environmentally sound development, namely development that does not damage ecosystem functions and environmental balance. Thus, environmental law review can provide recommendations that can be used as a reference for stakeholders in making decisions related to environmental issues.

Published: December 2024

Abstract
This study explores the combination of reverse engineering (RE) and new product development (NPD) methodologies to enhance the manufacturing process of headlamp jigs. RE, utilised as a benchmarking technique, aids in regenerating parametric designs or innovating new product concepts. The distinctive appearance relies on headlamps with protective coatings cured at high temperatures in UV ovens, necessitating jigs capable of withstanding such conditions. Hence, employing RE becomes crucial to fortifying jig performance. While RE often signifies innovation or refinement, the current headlamp jig encounters deformation issues during manufacturing due to high curing oven temperatures and intense water jet cleaning pressures. The absence of an effective NPD approach exacerbates persistent jig deformation challenges. NPD, encompassing stages like idea generation, concept development, design, testing, and marketing, is crucial. The absence of NPD, along with the complexity of RE, could prolong timelines and escalate expenses in bringing marketable products to fruition. This study aims to propose an NPD model for headlamp jigs, leveraging RE methodologies to enhance composite jig fabrication processes. The integration of PDCA methodologies within NPD intends to rectify deformation issues while optimizing manufacturing processes for superior headlamp jigs.

Authors: Irfaudin M , Putra D P E , Taufiq A. 
Published: December 2024

Abstract
The southern sub-district of Pujut, which encompasses Mandalika’s Special Economic Zone, is a region focused on industrial and tourism growth. Groundwater supplies are necessary to fulfill the demands of the local population and the tourism sector. In groundwater exploration, one of the important parameters is hydrochemistry, whereas, in the research area, more studies are needed on this topic, especially in relation to hydrogeological conditions. The objective of this research is to comprehend the hydrochemical properties of the groundwater system present in this region. A total of 9 samples from drilled wells and 2 samples from springs were collected and assessed to ascertain the concentration of primary ions. The diagrams developed by Piper and Stiff were employed to categorize the groundwater facies and establish their correlation with the geological conditions. The results revealed that the chemical composition of the groundwater was classified into four unique categories, demonstrating differences in facies and groundwater systems. Group 1 comprises Ca-Mg-HCO3 facies characterized by bicarbonate water and is associated with calcarenite limestone and volcanic breccia. Group 2 is the Ca-Cl facies, distinguished by the presence of water rich in chloride. These facies are characterized by the occurrence of saline or brackish water associated with calcarenite limestone and are frequently observed in close proximity to the shoreline. A mixture of Na-Cl-SO4 characterizes group 3. The concentration of sulfate ions is high in this group, and their existence is due to the oxidation of sulfide minerals in altered volcanic breccias. Group 4 is the mix of Ca-Na-HCO3 type and is associated with alluvium deposits. Based on the previous explanation, groundwater that has the potential to be exploited is groundwater in the Ca-Na-HCO3 and Ca-Mg-HCO3 facies. According to the explanation, the groundwater that can be utilized is the groundwater in the Ca-Na-HCO3 and Ca-Mg-HCO3 facies.

Collaborative research studies with the theme of ethnobiology with national parks have recently become a trending topic of discussion. This study aims to examine the development trend and gap of excellence of ethnobiology topics in the management of national park areas in a sustainable manner. This study uses data from academic journals published between 2004 and 2024 to understand the research trends, main topics, and leading authors of national park management in the view of ethnobiology. The data were analyzed with Vosviewer 1.6.19 software and Biblioshiny application, R-Package Bibliometric software, and R-Studio 4.4.1. The analysis revealed that the main topics of ethnobiological studies in national parks include ethnobotany, medicinal plants, conservation, and biodiversity. However, in the last ten years, the research themes featured, and the resulting publications still need to be higher, namely research topics towards ethnobiology, fauna/ethnozoology, plant utilization, local ethnicity, and rural communities. Collaborative research is necessary to obtain new ideas and research formulations such as ethnobiology, ethnozoology, ethnoecology, and ethnic/rural communities in national park management strategies for sustainable development.
Decoding carbon neutrality targets: insights from Indonesia’s economic and energy perspective
Authors: Valeriani D , Sah T 
Published: December 2024

Abstract
To achieve carbon neutrality, it is essential for Indonesia to promote the integrated development of its energy, environmental, and economic systems (3E). This research examines the potential integration of economic growth, energy intensity, and renewable energy consumption into efforts to reach carbon neutrality in Indonesia. Utilizing data from 1990 to 2020, the study investigates the impact of these factors on CO2 emissions through multiple linear regression analysis. The findings indicate that economic growth, energy intensity, and renewable energy consumption are pivotal in pursuing carbon neutrality. While economic growth slightly contributes to CO2 emissions, the effect is not statistically significant, although the ecological Kuznets curve is observed. On the other hand, increased energy intensity significantly raises CO2 emissions, presenting a challenge to meeting carbon neutrality goals. Conversely, greater use of renewable energy has a notable effect in reducing CO2 emissions and supporting carbon neutrality efforts. Key policy recommendations include advancing a green and digital-based economy, expanding clean energy utilization, and adopting sustainable green technologies.

Published: December 2024

Abstract
Biogas potential assessments indicate that low-income countries have biogas resource potential to substantially contribute to the clean cooking transitioning and also reduce carbon emissions linked to the use of solid biomass as cooking fuels. However, the estimated biogas potentials have not been harnessed, and its contribution to the clean cooking targets remains off-targets. Literature often focuses on barriers to the technology adoption and diffusion. There is lack of mechanisms to monitor the gas production and management, specifically at small scale use. This study combines smart biogas metering and remote monitoring of biodigester conditions to ascertain user-end dynamics for a family-sized biodigesters use. Daily biodigesters’ health is remotely monitored using IoT device. Biogas production, usage, leakage, and venting are used to study the role of technology biogas production and management and its contribution to clean cooking pathways, as well as Green House Gas (GHG) emissions mitigations. Findings indicate that the success of the technology is not only hindered by barriers reported in literature. Rather, user practices affect the biogas production and management. Results emphasise the need for developing mechanisms to enhance energy demand side management, irrespective of the primary resource, resource-to-energy conversion technology, and scale of use.

Published: December 2024

Abstract
Indonesia’s Ministry of Public Works and Housing initiated the Rumah Susun (Rusun) program to provide adequate housing for middle-to low-income families. The first Rusun, built in East Jakarta in 1989, pioneered multi-story housing in the country. For a residence to be habitable, it must meet health and comfort requirements, such as regarding lighting and ventilation. This study evaluates the 35-year-old Rusun’s building performance and human comfort in two adjacent units with opposite orientations to assess its compatibility with the current climate. Thermal and visual comfort data was gathered through direct measurements and occupant questionnaires. Results indicate that residents find the units rather uncomfortable nowadays, with warm thermal conditions and inadequate illumination. Given the rise in global temperatures over the decades, the field measurements confirmed that both units failed to meet Indonesian National Standards for lighting and ventilation. This study highlights the importance of improving building physics in future Rusun designs to enhance occupant health and comfort.

Abstract
Amidst the challenge of providing Green Open Space (GOS) due to urban area expansion, the existing GOS has not been utilized optimally. Hence, it raises the need to evaluate the type of GOS optimally used by the public. This study evaluates one of the popular GOS in Jakarta, Tebet Eco Park (TEP), by investigating the digital perception of YouTube users. This qualitative study used Nettlytic to scrape YouTube comments on the five most relevant videos related to TEP from 2022 to 2024 as samples to be analyzed. The study identifies key themes: like, dislike, neutral, questions, and criticisms from 462 relevant comments. Through those comments, this study revealed the public acceptance of TEP, which showed that most of them like the park. Greenery, atmosphere, and concept are the most appreciated features of the park. However, some features still need to be evaluated, such as the parking area, crowd control, plant maintenance, and spreading information about the park. This research provides evidence of the ability of online platforms as one of the GOS evaluation tools. It contributes to developing Jakarta s public space in the future by providing insight for further research and policy about GOS.

Abstract
This research aims to analyze the legal formulation for regulating the use of plastic bags to control pollution and environmental damage in Bangka Belitung. The method used is empirical juridical research. The research results show that the Bangka Belitung Islands Province is the 4th province in Indonesia, whose rivers are polluted by microplastic waste. Regional governments can take mitigation at the provincial and district/city levels of the Bangka Belitung Islands to control pollution and environmental damage due to plastic bags by increasing community participation in using non-plastic bags and involving producers or business people responsible for governance. Plastic waste by applying the principle of internalization to every use of plastic bags. Furthermore, through the Waste Management Law, Indonesia has normalized the Polluter Pay Principle for plastic producers, but the Waste Management Law has not been effective in the field. Meanwhile, for formulating regulations on the use of plastic bags in Bangka Belitung, it is best to use regional or regional regulations. Currently, there are only two districts that have special rules regarding the use of plastic bags.

Published: December 2024

Abstract
Indonesia is the main palm oil producer in the world. It provides almost half of the total palm oil production in the world. Smallholder farmers owned 40 percent of 8.5 million hectares in 2012. Unfortunately, Indonesia suffers from many critics for environmental compliance. Sustainable management practices for palm oil production for soil fertility, nutrients, biodiversity, energy, social and human capital, pest management, and any other issues are still challenging for smallholder farmers. Perception and awareness of smallholder palm oil farmers in Riau for sustainable management practices will be elaborated. Knowledge and experiences for practicing sustainable management palm oil industry will be collected through observations and in-depth interview with 20 farmers from 2 different areas as well as Village Unit Cooperatives or Koperasi Unit Desa. Data from previous researches, official reports, news, and websites belong to palm oil institutions will be utilized to complement the study. Evidence showed smallholder farmers lack information of soil fertility, biodiversity, and pest management. Land clearing by burning was considered faster, cheaper, and more effective to reach non-acidic pH level so nutrients are available to the roots. Biodiversity was threatened by burning practices. High demand on palm oil drove them to convert traditional/local plants to palm oil even ignoring paludiculture since 62 percent of land in Riau are wetland. Organic fertilizers were utilized combining with mucuna bracteata (MB) to cover crops.

Authors: Alali Hasna Abdullah , Tiss F , Omri K , Alamer Kawther , Alhashem Zakia H 
Published: December 2024

Abstract
Manganese-doped zinc oxide (Zn/Mn) nanostructures were synthesized via the hydrothermal method, varying the manganese content. The synthesized Zn/Mn nanostructures exhibit a hexagonal wurtzite structure with an average crystallite size ranging from 19 to 33 nm, as determined by x-ray diffraction (XRD) analysis. Increasing Mn concentration induces a blue shift in the energy bandgap (Eg) of the Zn/Mn nanostructures, decreasing it from 3.26 to 3.15 eV. The photocatalytic performance of these nanostructures was evaluated by studying the degradation of methylene blue (MB) under ultraviolet light irradiation. The incorporation of Mn content systematically enhanced the photocatalytic activity of ZnO, with the highest (73%) was observed in Zn/Mn_4 nanostructures. Additionally, the degradation mechanism has been addressed.
