Published: December 2023

Abstract
Ensuring the safe value of agricultural products is crucial for the sustainable development of agriculture, which requires the rational use of both chemical and biological products. However, the use of current agrochemicals can adversely affect the beneficial microorganisms in soil and reduce their efficacy. This study aimed to evaluate the impact of 16 commonly used agrochemicals on five microbial species, including Bacillus sp., Pseudomonas sp., Saccharomyces sp., Azotobacter sp., and Trichoderma sp. The evaluation criteria comprised the assessment of direct effects at the time of exposure and after three days. The research results indicated that agrochemicals have a negative effect on experimental microorganisms. Specifically, when in direct contact, the chemical components ethoprophos, metalaxyl, and mancozeb contained in 2 out of 16 chemicals exhibited a 100% negative impact on all 5 species of microorganisms, while the other chemical components present in the remaining chemicals had an impact level of over 75%. Based on the experiments conducted, the results suggest that the appropriate time to use microbiological preparations is at an interval of 7 days after the application of the aforementioned agrochemicals.

Abstract
The challenges for the Bali ceramics industry come from the emission side of the materials, production, and waste processing. In the future, the Balinese ceramics industry must develop to be greener and more sustainable. One of the way is reducing emissions from raw materials process. This research was conducted with the aim of mapping the potential of clay that can be used as a raw material for making ceramics, especially those from Bali. The method used was to review the literature on ceramic raw materials and conducted a survey to compile flow diagrams of materials, energy, and emissions from ceramic production in Bali. Then calculated the carbon dioxide (CO2) emissions that arise with the clay scheme come from inside and outside Bali. The results of the study indicate that there is potential for the use of clay from Buleleng and Tabanan areas, which can reduce carbon dioxide (CO2) emissions of the Balinese ceramic industry. However, its use needs to be re-examined from a process perspective because it has a higher iron oxide (Fe2O3) composition.

Abstract
Lake Singkarak, located in the West Sumatra Province, resulted from a tectonic process affected by the Great Sumatran Fault. The lake has a total area of 107 km2 and is used for fisheries, tourism, hydroelectric power plant, etc. However, this lake is facing an array of issues and is even considered in a critical condition. Population growth, land use changes, agriculture development, and climate change are suspected to be the causes. It was also aggravated by the COVID-19 pandemic, wherein lake maintenance was neglected. The lake is a system, therefore maintenance of the lake cannot be performed partially and sporadically but must be integrated and comprehensive. This research analyses factors affecting the lake’s sustainability and the linkage between those factors. This research employed a system thinking approach. There are direct and indirect links between social, economic, and environmental factors, as illustrated in a Causal Loop Diagram. This diagram depicts how economic activities are constrained by available potential, which, at certain thresholds, may result in a drop in lake quality if managed in an unsustainable manner. Additionally, lake management appears to be an important factor in overcoming existing issues and establishing a sustainable lake.

Published: December 2023

Abstract
Daylight plays important role in achieving good Indoor Environment Quality (IEQ) because it contributes to human health and optimal working performance. The Engineering Center (EC) building, which is part of Universitas Indonesia in Depok, Indonesia has great daylight potential with an existing design Window-to-Wall Ratio (WWR) of 100%. However, this potential has yet to be maximized due to use of artificial lighting during the day. Moreover, the uneven distribution of sunlight entering the room creates some issues (i.e., glares, dazzled, heat and low uniformity level). This research tries to improve this condition by intervening in Window to Wall Ratio (WWR) and adding Light Shelves (LS) in class 101 (facing south) and 102 (facing north). 56 variations of WWR and LS were simulated using Rhinoceros (RH) and Grasshopper (GH) software with plug-ins (Ladybug and Honeybee). The simulation results show three design configurations WWR 60% - LS straight; WWR 78% - LS straight; and WWR 60% - LS curve in room number 102 facing north produce illuminance close to the maximum and minimum threshold for good lighting in the classroom (350 - 500 lx). This study will provide reference strategies for improving daylight performance in university classrooms with tropical climates.

Abstract
The exploitation of groundwater on the northern slope of Mount Lawu, Ngawi, East Java, Indonesia is increasing due to agricultural use. To maintain the existence and sustainability of groundwater, the first step is to know the groundwater occurrence in the area. The objective of this study is to analyze the groundwater occurrence in the study area, the groundwater flow pattern, and the physicochemical properties of groundwater such as pH, Temperature, Total Dissolved Solids (TDS), and Electrical Conductivity (EC). The research methodology involved field hydrogeological observation and analysis of data processing using the Geographic Information System (GIS). Hydrogeological observation activities involve direct observation and measurement of 4 springs, 14 deep wells, and 42 dug wells located on the northern slope of Mount Lawu. The result of this research indicates that in both shallow and deep groundwater, the pattern and groundwater flow direction are from south to north and then parallel to the flow of the Bengawan Solo River. The physicochemical characteristics of the deep well water show similarities to those of the dug well water. Based on the findings, the groundwater system in the research area can be presumably developed by only a single groundwater system or two interconnected groundwater systems.

Abstract
Urban development in sub-urban areas occurs due to the agglomeration of residential areas which form a functional unity in urban activities. Continuous urban development will give rise to urban sustainability problems, one of which is the lack of available green open space to support the natural ecological cycle of a sustainable urban environment. Green Open Space as Creative Public Space can boost the regional economy because it is able to attract people to gather for recreation, play and work and has opened up opportunities for the development of the creative economy market. The Green Open Space of Sekartaji Park, Kediri City, can become a Creative Public Space, but it still experiences obstacles so it must be arranged according to the criteria and function of Creative Public Space. This research aims to utilize green open space into public open space. This research uses a qualitative descriptive research method. Data collection was carried out using literature studies, interviews and observations. The results of this research are the use of green open space as Creative Public Space with facilities and infrastructure for local economic activities, creativity-innovation in art, culture and social interaction.

Published: December 2023

Abstract
A new sorbent based on ion-imprinted polymers has been successfully synthesized to examine chromium(III) in environmental water samples. In this study, Cr(III)−IIPs was synthesized using Cr(III)−DPCO complex as a templating molecule, and ethylene glycol dimethacrylate (EGDMA), methacrylic acid (MAA), and benzoyl peroxide (BPO) as crosslinking agent, functional monomer, and radical initiator, respectively. The fabricated Cr(III)−IIPs polymer was characterized using Fourier transform infrared (FTIR) spectroscopy and Scanning electron microscope (SEM). The FTIR results confirm that Cr(III)−IIPs has been successfully synthesized. A peak at 495 cm-1 indicated the stretching vibrations of Cr−N. The firm peaks at 1732 cm-1 and 1163 cm-1 are assigned to C=O and C−O stretching vibrations of methacrylic acid. The broad and strong peak at 3483 cm-1 corresponded to hydroxyl bonds between the templating molecule and functional monomer. The SEM images revealed that the morphology of the polymer was irregular and large. The Imprinting factor (IF) values of Cr(III)−IIPs/NIPs−DPCO and Cr(III)−IIPs/NIPs were 3.12 and 1.53, respectively. The sorbent developed by this technique can be selective to the target ions.

Abstract
The provision of electric charging facilities in public areas, public transport depots, logistics depots, logistics consignment hubs, and residential areas is targeted for Indonesia’s new capital city (INCC) in pacing the (near to) zero-emission in the transport sector by 2045. Hence, the supportive electric mobility infrastructure should gradually be merged from the design stage to achieve directed goals. However, since the planning process for grid-supporting infrastructure is undergoing or within the preliminary phase or has not been done yet, there is a lack of required data, i.e., the rollout number of electric vehicles (EVs) units, sizing areas, and the compliance interconnection feeder. Meanwhile, using practical estimations or averaging techniques could lead to significant discrepancies, particularly regarding grid-supportive investment planning, i.e., redesign for grid capacity assets. On that concern, the paper constructs a model-driven using the predictive Monte Carlo method (MCM) to generate power load patterns, mimicking behavior-alike of residential home chargers for two|three|four wheeled EVs (2|3|4 WEVs) providing high-resolution power consumption data over unknown parameters related to the EVs properties, user behavior charging timeframes, and the expected tailor-made platform (sizing and allocation). Therefore, the findings are expected to be evidence-based replanning policy for policymakers, energy planners, and utilities.

Abstract
Since the distance past, Indonesia has been notable for its abundant biological resources. This is partly influenced by the geographical factors. This abundance is also possessed by the Bangka Belitung Islands, including South Bangka Regency. Based on data processed from the National Data on Indonesian Communal Intellectual Property, there are six traditional cultural expressions and seven ancestral knowledge recorded in South Bangka. This means that no genetic resources are legally registered. However, there is a lot of potential. Moreover, this district geographically differs remarkably from other regions, one of which is its numerous small islands. On the other hand, this area comprises tin mining locations which have a direct impact on the environment, including sites that have been recognized as habitats for genetic resources, both flora and fauna. This research uses empirical judicial methods, associating regulations with the facts that occur. The data used is primary data obtained from interviews and focus groups discussion, as well as secondary data obtained from literature studies of a number of documents. The results of the studies carried out showed that the protection of communal intellectual property of genetic resources is facing several serious problems, one of which is environmental damage. This is due to the massive tin mining activities, as well as the pepper gardening system which has always been on the move since earlier period. This means that environmental management in the region has an impact on the protection of genetic resources, including legitimately.

Abstract
Roster brick or commonly known as breeze blocks is one of the most used building elements in tropical countries because of its functionality and versatility. Its function varies from being used as a vent in service areas to an element for architectural façade. This hollow concrete block can be used not only for aesthetic values but also for improving passive design strategies through air and daylight. However, the geometric configuration of the roster is currently still relying on the creativity and intuition of the roster’s craftsmen. Therefore, this study investigates the optimal roster geometry shape which accommodates multiple performances by using the integration of multi-objective optimization (MOO) and material fabrication methods. The use of MOO serves the purpose of finding near-optimum solutions among conflicting building performance objectives. The MOO result is 57 generations with 90 genes identified in the last generation. The first near-optimum design options are capable of obtaining daylighting as much as 87% with UDI metric, flowing wind velocity up to 1.98 m/s, and experiencing structural displacement until 0.36 mm. This study provides a valuable contribution to form-finding a high-performance building element, in this regard roster brick.

Published: December 2023

Abstract
Phenothiazine-derivatives are designed as sensitizers which covalently-linked with BODIPY for application in a system of dye-sensitized photoelectrochemical cells (DSPECs). A series of phenothiazine-linked-BODIPY as D-D-π-A chromophore have been investigated by a computational approach for studying the capability of the photosensitizers for application in photoinduced water splitting hydrogen production in DSPECs. The geometries of sensitizers at the ground state and excited state were optimized by the CAM-B3LYP/6-31G (d,p) level method. The theoretical study has been done in order to investigate the photophysical properties such as absorption profile, HOMO-LUMO energy and surface plots of the photosensitizer. The result of calculation for HOMO-LUMO energy level of each dyes showed that the LUMO energy are ranging more than -2.8 - (-2.86) eV which is higher than -4.0 eV of conduction band of TiO2 as semiconductor in DSPEC, meaning that all these dyes could be used as photosensitizers in DSPECs. In addition, the oscillator strength data of each dyes showed the dyes have absorption profile in visible region, meaning the dyes could harvest higher intensity of sunlight to induce water splitting reaction to produce hydrogen.

Published: December 2023

Abstract
Aruk rice is a typical food from the Bangka-Belitung Islands Province. Aruk rice is made from fermented cassava to extract and process the flour into granules. Much research has been done on aruk rice made traditionally. One of the main problems in making Aruk rice is that it takes a long time, which is 7–10 days. This affects the production rate of Aruk rice. Adding a starter can overcome the relatively long process of making Aruk rice. The purpose of this study was to analyze the effect of perceived product quality on satisfaction and the intention to re-consume Aruk rice with the addition of a starter. The research method uses a survey method. The sampling technique used was purposive sampling with a total of 100 respondents. Respondents in this study were people who had consumed traditional Aruk rice. Research data were analyzed by SEM-PLS using SmartPLS Software version 4.0. The results showed that directly, perception of product quality had a positive and significant effect on people’s satisfaction when consuming Aruk rice with the addition of an environmentally friendly starter. However, the perception of product quality has a negative and significant effect on the intention to re-consume Aruk rice with the addition of an environmentally friendly starter. People prefer to consume Aruk rice traditionally because they are used to it. Nonetheless, it was observed that satisfaction positively and significantly influenced the intention to re-consume Aruk rice when the environmentally friendly starter was used. Moreover, the perception of product quality indirectly influenced the re-consumption intentions of Aruk ricebby adding the starter. These finding offer an opportunity for Aruk rice makers to enhance the product’s quality to meet consumer desires, potentially increasing consumer intentions to re-consume Aruk rice.

Published: December 2023

Abstract
R1234yf, a low global warming potential (GWP) refrigerant, offers a promising alternative to traditional refrigerants like R134a. This study analyzes automotive air conditioning systems (AAC) equipped with electric compressors and utilizing R1234yf refrigerant. The interrelationships between refrigerant charge, compressor speed, power consumption, cooling capacity, and energy efficiency are examined. The results show that increasing refrigerant charge and compressor speed leads to higher power consumption due to increased compressor work. However, higher refrigerant charges and compressor speeds improve cooling capacity in line with heat transfer principles. As refrigerant charge and compressor speed increase, the energy efficiency, measured by the Coefficient of Performance (COP), tends to decrease, indicating a trade-off between cooling capacity and energy efficiency. Optimizing refrigerant charge and compressor speed is crucial to strike a balance between cooling performance and energy efficiency. R134a outperforms R1234yf, with an average percent difference in COP approximately 25% higher at all compressor speeds. This study contributes to the understanding of AAC system performance and guides the development of energy-efficient automotive air conditioning. Future research can further explore system components and conditions to enhance energy efficiency and advance air conditioning technology.
