Authors: Fathana H , Dewi K U 
Published: December 2023

Abstract
This research discusses the implementation of Sustainable Development Goals in Yogyakarta, Indonesia, particularly in the Malioboro area. The questions to be addressed are: how have the Yogyakarta governments recontextualized the concept of sustainability in managing Malioboro? To what extent are the concept of sustainable cities perceived by Yogyakarta governments? This research argues that the government of Yogyakarta has put an effort to recontextualize Malioboro as a part of a sustainable city in achieving the target set by Sustainable Development Goals (SDGs). The recontextualization starts by first creating an ideal environment in the area in which there will be equal opportunities for anyone who is a member of the society. This would lead to a changed social structure that could enable the society to thrive as they are able to further explore the potential provided by the previously-mentioned equal opportunities. The changed society due to a better environment would lead to a more economically prosperous society, and therefore achieve the sustainable development as targeted by the government.

Abstract
Health issues in the 21st century have become essential in addition to sustainable development issues. Health is an urgent need to find solutions to problems so that human health is always maintained. Health issues are also influenced by the built environment, one of which is studied in the concept of healthy building. A healthy building has several criteria that can be a point of view to see if the building is healthy or unhealthy. Physiological, psychological and disease transmission problems are the main problems faced by users who use unhealthy buildings. Biomimicry architecture emerged due to technological and scientific advances, in which cross-disciplinary science has become the power of knowledge today. Biomimicry architecture is a design approach that uses nature to solve human problems. Health problems and the need to produce healthy buildings can use biomimicry architecture as a problem-solving method. This paper uses a descriptive qualitative content analysis method on various written references related to biomimicry architecture and how biomimicry architecture produces healthy buildings. The conclusion of this study shows that biomimicry architecture is an approach to using natural inspiration to solve human problems, one of which is building health. Implementing principles found in nature delivers buildings designed with a biomimicry architectural approach to be healthier. That is due to the successful application of natural traits that are always adaptive, efficient, effective and live in line with the environment in the built environment.

Published: December 2023

Abstract
In this post-Covid-19 pandemic, the existence of a space that is connected to outside air circulation is a necessity. This is because good air circulation can reduce the potential for the spread of Covid-19 indoors. One of the challenges in implementing natural ventilation is the entry of excess solar heat into the building. One strategy that can be done to avoid the entry of excess solar heat is to use shadows to filter sunlight. This study examined the appropriate shading strategy that can be applied to overcome the problem of excessive solar heat in the ventilation section of office buildings in Jakarta. The research will be conducted using an experimental method, Sketchup’s Pre-Design simulation. The simulation results show that Eggcrate and Automated Blinds shading are two types that can reduce harmful solar heat entering the building the highest compared to other types of shading.

Abstract
A thermal environment is an affecting factor toward students’ comfort and health at school. One thing that gives an impact on the thermal environment is the selection of building materials, which is influenced by the thermal mass. The use of wooden materials has high potency in reducing global warming and supporting increased thermal comfort. This study aims to explain the inspection result of the school building which has 2 types of buildings, namely the wooden building and the concrete building. The purpose is to find out how the thermal environment is formed in the classrooms in those two buildings and the potential of wood materials. This study used a field measurement method where the case study building was SDN 14 Pontianak. The obtained result indicated that the air temperature variable showed the same phenomenon at each measurement time. The air temperature in the wooden building was always lower compared to the air temperature in the classroom of the concrete building, where the difference reached 2,68 °C. The other variable showed varied phenomena so a general conclusion could not be drawn. It might be affected by other aspects which were not calculated in this measurement.

Abstract
The present study aimed to study the effect of magnesium sulfate and ammonium nitrate on the chemical activity of phosphoric acid solutions. The results of studies on increasing the chemical activity of extractive phosphoric acid from Central Kyzylkum and Karatau phosphorites due to the concentration of the first hydrogen ions and the pH of the medium are presented. It has been shown that introducing magnesium sulfate heptahydrate into the acid reduces the concentration of the first hydrogen ions. Adding an amount of ammonium nitrate increases the concentration of the first hydrogen ions even higher than in the acid without magnesium. It has been established that the solubility of magnesium hydrophosphate increases with an increase in the content of P2O5 phosphoric acid, dihydrogen phosphate decreases as a result of dissociation with the formation of a hydrophosphate ion, and phosphoric acid dissociates with the formation of a dihydrophosphate ion, which binds with hydrogen ions, forming a dihydrophosphate ion.

Published: December 2023

Abstract
Polyunsaturated fatty acids are considered a benefit for human consumption because they are available in edible oils and enhance their susceptibility to oxidation. The Fourier Transform Infrared spectroscopy (FT-IR) method was applied to evaluate the oxidation in edible oils and the chemical changes. The oxidation could be accelerated by the application of heat with air. Therefore, five types of oils, soybean oil (SBO), sunflower oil (SFO), sesame oil (SEO), corn oil (CRO), and palm oil (PAO), were taken and heated at the temperature of 85±2°C with aeration at the rate of 5 L/sec for 55 hours continuously. Thiobarbituric acid reactive substances (TBARS) were determined to compare the results. Comparing the spectra of exposed and unexposed oils, PAO and CRO have undergone fewer changes than other oils, whereas more changes have occurred in SFO than other oils. Between the other two oils, SEO showed the highest level of oxidation, followed by SBO. Results obtained in this study indicate that FT-IR is a proper rapid technique for measuring oxidation in edible oil.

Published: December 2023

Abstract
The waste sector contributes 21 times more Greenhouse Gas (GHG) in the form of methane gas than carbon dioxide gas. The problem of waste management in Indonesia is caused by several factors, including the need for more strict regulations and a management system at the landfill. Gunung Kupang Final Processing Site is a landfill that serves the Banjarbaru City area, where the waste that enters every day continues to increase and can potentially cause emissions. The management system implemented is still limited, namely composting and recycling methods. The management of methane gas produced from waste generation has not been maximized because there has yet to be a comprehensive measurement of methane gas. This study aimed to analyze the characteristics of waste generation and composition and the estimation of methane gas from the Gunung Kupang Final Processing Site using the LandGEM method. The urgency of measuring methane gas in waste management at Gunung Kupang Final Processing Site is the focus of this research, which is projected to encourage local governments to formulate appropriate and targeted waste management policies.

Published: December 2023

Abstract
Green low-carbon technology development has spurred an increased demand for lithium. Brine, including geothermal brine, is the world’s largest source of lithium. However, the low lithium content and the presence of other ions pose challenges in concentrating lithium. An electric field-assisted membrane is a separation approach combining nanofiltration membranes with an electric field as an additional driving force, effectively separating lithium from magnesium and strontium. This study was conducted to separate lithium and calcium from synthetic geothermal brine using an electric field-assisted membrane. The separation process is conducted for lithium (50 ppm) and calcium (300, 800, and 2,000 ppm) with variations in electrical voltage (0V, 2V, and 3V). The decrease in lithium rejection reaches up to 50% at an electrical voltage of 2V. Conversely, the increase in electrical voltage does not significantly impact calcium rejection (calcium rejection remains at 89% with an electrical voltage of 3V) and the permeate flux for lithium and calcium. The increasing calcium concentration affects permeate flux significantly but does not notably affect calcium rejection, with the rejection remaining above 85%. The findings suggest the feasibility of concentrating lithium through electric field application without compromising calcium rejection within a single salt solution system.

Abstract
Plastic waste continues to increase by 4% every year. One type of plastic is Styrofoam, which comes from polystyrene (PS) polymers. However, Styrofoam has the disadvantage that it is not easily decomposed in nature. It is necessary to replace plastic-based food containers using biodegradable, abundantly available, low-cost natural materials. This research uses rice straw and bagasse with the addition of orange peel to give the best results on water absorption, tensile strength, and degradation time in food containers. The orange peel addition is varied at 0%, 5%, and 10% (w/w). In the water absorption test, the best value was obtained at 10.95% for the bagasse container with the addition of orange peel at 10% (w/w). In contrast, the best water absorption for the rice straw container was 11.02%, with the addition of orange peel at 10% (w/w). In the tensile strength test, the best value was obtained by the bagasse container at 6.592 MPa with the addition of orange peel at 10% (w/w) and rice straw at 4.3812 MPa with the addition of orange peel at 10% (w/w). Degradation tests showed that these natural containers can be degraded within two months in the soil.

Published: December 2023

Abstract
Bamboo has been known for its sustainability and versatility, which presents a promising green alternative material from tropical countries. This paper explores bamboo’s potential as an encapsulation material for liquid phase change material (PCM), addressing leakage and fungal growth. The experimental procedures involve treating two different types of bamboo (black and tropical green) to see their capability as an encapsulation for phase change material. In addition, three experiments were applied: waterproofing, varnish, and pre-treatment. Qualitative analysis is conducted over a consecutive fourteen-day period, evaluating all the twenty different samples with different treatments as they hold the liquid PCM. Several pre-treated bamboos show leakage. Consequently, varnishing and waterproofing treatments emerged as crucial in effectively addressing bamboo encapsulation. The findings demonstrate that tropical green bamboo, treated with waterproofing on both sides, exhibited impeccable leakage prevention and successfully removed fungal growth, even when exposed to extended periods of moisture.

Published: December 2023

AbstractTo avoid ecological catastrophe, most cities are moving toward green building. The critical component is greening – conventional and green structures. Urban agriculture is a very prospective direction. Green roofs, terraces, and rooftop greenhouses are the most promising places for growing. This solves multiple tasks: heat loss recovery for planting (for rooftop greenhouses), additional thermal insulation, optimized logistics, increasing pollinator populations, avoiding pests, etc. In different-height districts, there are problems with natural illumination and winds. No good urban wind theory has been developed. The winds can be simulated in CFD software using a 3D model of a district. Most of the software can simulate solar radiation for thermotechnical calculations only. It should be simulated in other special software. The approach to calculating solar radiation is proposed using CFD software without additional needs. The unique "integrator" material should be added to the engineering database. Its thermotechnical properties can be set to obtain a temperature numerically equal to the exciting parameter. Application is shown in an example of a different-height building with a green roof. The results show areas most favorable for growing photophilous and shade-tolerant plants and placing cleaning and phytoncidal plants for maximum air quality in stagnation zones.

Published: December 2023

Abstract
SLR could affect the waters of Palabuhanratu Bay, which are exposed to the Indian Ocean. Sea levels are rising due to RSL and ASL changes. RSL has increased by 22.86 mm/year based on tidal data for 2013–2022. In contrast, ASL has increased by 4.48 mm/year based on satellite altimetry data for 1992–2022. The research uses the linear regression method to get the SLR value. According to earlier studies, dynamic change elements connected to alterations in the atmosphere and ocean circulation are typically considered when analyzing sea level variations. This work explores sea-level variations, including dynamic and static changes impacted by geological processes like deformation. Dynamic change factors, such as climate anomalies, ENSO, and IOD, affect these changes. Regarding RSL changes, ENSO has a more decisive influence than IOD, and vice versa for ASL changes. In the La Nina phenomenon and negative IOD phase, RSL and ASL trend changes are enhanced, whereas they are lowered in the El Nino and positive IOD phases. These waters’ sea-level variations are only slightly impacted by local processes, such as VLM. It has a more decisive influence on RSL changes than ASL.

Abstract
Mulching is considered as a sustainable farming practice that promotes environmental conservation and improves productivity. The study was carried out to evaluate the determinants of mulching adoption among cacao farmers in the province of Camiguin, Philippines. The study was administered to 87 out of 201 cacao farmers using stratified sampling technique in the entire province of Camiguin last March 2023. Data collected were subjected to probit regression analysis using free software RStudio and R 4.3.0, where the dependent variable was the adopters of mulching, and the independent variables were age, access to extension workers, experience in cacao farming in years, knowledge, and training of mulching. Results from the probit model revealed a positive and strong relationship between adoption and knowledge of mulching (p-value=0.01) and training of mulching (p-value=0.01). The current study provides empirical evidence that knowledge and training are two vital determinants of adoption on mulching among cacao farmers in Camiguin. Educating farmers about mulching improves their knowledge and skills and increases productivity on their farms to attain sustainable agricultural production. Further studies may be conducted to assess the economic impact of adoption on farmers’ income and well-being.
