Published: December 2021

Abstract
Irrigation water demand in the command area is affected by rainfall and climate conditions in the river basin. In climate change conditions, rainfall and temperature are predicted to increase and projected to impact irrigation water requirements significantly. Therefore, understanding the climate change effects on irrigation demand in the command area is significant to the river basin manager and planner for managing water resources effectively. This study aims to predict the impact of climate change and irrigation efficiency improvement on the irrigation water requirement in 2032-2040. This study used the CropWat model to estimate irrigation water requirements in 1995-2005 and 2032-2040. Irrigation water demand in the Dodokan watershed as a part of the Lombok river basin was computed using the historical rainfall and climate data from observation stations. Further, the observed data from 2006 to 2014 were projected into climate change in 2032-2040 as an input for the model to predict the demand in corresponding years. Result suggests that the change of annual irrigation water demand in the Dodokan watershed was expected to rise by 1.61% in 2032-2040 compared with 1995-2005, and irrigation efficiency improvement effort would decrease the demand -18.18% in the climate change period.

Abstract
The initiative to relocate the capital of the Republic of Indonesia from Jakarta to Penajam Paser Utara requires research from various sectors in the area. Since Penajam Paser Utara is located in the coastal zone of Balikpapan Bay, it requires careful preparation. This research aims to examine the characteristics of wind-generated waves in the Balikpapan Bay area from 2016 to 2018. Bathymetry data from BATNAS with a resolution of 0.00166666° and Wind data (U10 wind velocity and direction) from the European Center for Medium-Range Weather Forecasts (ECMWF) with a resolution of 0.25° × 0.25° were utilized as input data in this study during three years (2016-2018). This research used the SWAN Model to model wind-produced waves to get significant wave values in spatial and time series form and monthly and seasonal wave energy spectrum characteristics. Based on this research, it can be concluded that significant wave height values are strongly correlated with wind speed. The highest wind speed is found in the DJF (Transition I) season. Maximum Hs (wave height) is found in DJF season, while Hs tends to be high in SON (Transition II) as well as DJF (Western Season), and Hs tends to be weak in MAM (Transition I) season.

Published: December 2021

Abstract
Strong earthquakes occurred in Central Sulawesi, Indonesia, in late 2018, causing an inheritance disaster, soil liquefaction on Gumbasa Irrigation Canal at Petobo, Sulawesi. Soil liquefaction is a phenomenon of a decreasing soil bearing capacity triggered by strong vibrations in certain soil conditions. It immediately changes the soil characteristic from solid to liquid. Liquefaction vulnerability analysis was done using Idriss-Boulanger’s simplified procedure based on SPT value in several spots. The Petobo liquefaction zone has seven boreholes, five of which are located near the Gumbasa Irrigation Canal. The soil sample at those boreholes was taken to the laboratory for further soil testing using grain size analysis. The simplified procedure is intended to calculate the safety factor using Cyclic Resistance Ratio, Cyclic Stress Ratio, and Magnitude Scaling Factor. The liquefaction vulnerability analysis resulted in the AB 1 – AB 3 area near Gumbasa Irrigation Canal, which liquefied. Meanwhile, LP 1 and LP 4 are contrary. LP 1 is located upstream of the canal, whereas LP 4 the downstream. Grain size analysis yields a consistent result that AB 1 – AB 3 soil is quite scattered inside the liquefiable constraint.

AbstractGrowth in the construction sector could stimulate the development of other sectors. However, the construction industry has been known as a sector that brings a great contributes to energy consumption and produces Greenhouse Gases (GHG) emissions that harm the environment. To support the implementation of sustainable infrastructure, calculating the greenhouse gas emissions produced by a construction project through its lifecycle is necessary. This study analyzes greenhouse gas emissions produced in constructing a three-story precast building. The emission source was calculated from the materials, transportation activities, and erection activities using a Life Cycle Assessment (LCA) approach. The embodied carbon data was adopted from the Inventory of Carbon and Energy (ICE) database. From the analysis that has been carried out, the precast building project generated 124.882.7 kgCO2eq, or 283.18 kgCO2eq GHG per m2of building. The contribution of emissions from materials, the transportation precast components, and the erection of precast components was 119.649 kgCO2eq (95.81%), 632.41 kgCO2eq (0.51%), and 4,599.30 kgCO2eq (3.68%) respectively.

Abstract
Whether climate change is real or not, the daily basis phenomena and its evidences should be our concern nowadays. Yogyakarta is one of the provinces that are vulnerable to the impact of climate change in Indonesia. The specific responses to climate change phenomena in Yogyakarta province are indirectly correlated to landscape characteristics. These characteristics are important aspects for the assessment and development of new approaches to address the impacts of climate change. Therefore, this paper presents the status of landscape vulnerability to climate change in Yogyakarta province to consider the issues of mitigation and adaptation to climate change. Analytical hierarchy process (AHP) was applied to determine the objective of the research. The results of previous studies were reviewed in depth and combined with field observations to build a strong argument before evaluating the matrices and weights in the AHP steps. The result analysis showed that the most vulnerable landscape in Yogyakarta province is the anthropogenic landscape, which is located in Yogyakarta city. Furthermore, the combination of population density and poor sanitation management should be considered as a factor in mitigating and adapting to climate change in Yogyakarta city.

Published: December 2021

Abstract
Many aspects of the Pasar Baru community were influenced by the mixed ethnicity. Churches, Chinese temples, Sikh temples, and mosques, as well as architectural, gastronomic, and religious institutions, expanded across the Pasar Baru, resulting in a multicultural existence. The goal of this research is to see if there is a link between sacred space and community nodes as a signifier/signified of diversity in a multicultural community in order to enhance sustainable urban life. Also, based on the discovery of similar impacts, see if there is a strong recommendation to use the relationship between religious buildings and multicultural ethnic as a basis to construct a multicultural collaboration space. Pasar Baru and Geraja Ayam served as the case study. The semiotic theory of Ferdinand Saussure is employed as an analytical tool in this work. Gereja Ayam has become an icon of Pasar Baru district. Religious sites and community hubs have a strong association. While liveliness and livability can be improved, the (social) sustainability of tourism must be considered. The collaborative venue, which incorporates multicultural arts and designs, is proposed as a means of bringing those many traits to life and strengthening the concept of “Bhinneka Tunggal Ika” to generate income and employment.

Abstract
The Special Region of Yogyakarta is one of the areas that experienced a fairly high population growth rate and is directly proportional to the rate of development which has an impact on land use, especially in Tambakbayan watershed. This study aims to identify the types of land use that affected water quality of the Tambakbayan River using spatiotemporal analysis and Pearson correlation methods. Land use in Tambakbayan watershed is divided into three segments which are vegetation (VA), agriculture (AG), and building (BU). This study used water quality data from the Environmental Agency of Yogyakarta Province which consists of 14 parameters, i.e., pH, TDS, TSS, DO, BOD, COD, nitrate, nitrite, total phosphate, Zn, Cu, Pb, E. coli, and total coli. Landsat 8 image data from 2013 to 2020 is used from USGS. The result of this study found that vegetation has no correlation on Tambakbayan River water quality. However, agriculture and building areas significantly affected the decreasing water quality of the Tambakbayan River.

Published: December 2021

AbstractThe rapid growth of cities will certainly also increase traffic jams and emissions in the air. This study aims to analyze the increase in car volume and the CO distribution pattern in East Jakarta. Data for traffic jam patterns were recorded based on Google Maps on weekdays in the morning and evening. The spatial analysis method used to find the CO distribution pattern is the IDW interpolation, and the mathematical model calculates the moving emission based on the distance travelled (VKT). The spatial pattern of CO distribution in 2020 was scattered with high concentrations in Pasar Rebo, Ciracas, Cipayung, Kramat Jati, and Makasar Districts, with CO levels above 4,500 ppm. The spatial pattern of CO distribution from the mobile emission model differs from the air station IDW interpolation. The CO distribution pattern from the mobile emission model is very concentrated in Makassar, and Kramat Jati District was 6,740.91 tons/year. The result concluded that the increase in vehicle volume is not related to the distribution of the CO model from air station IDW interpolation, and the other hand, the congestion pattern was related to the distribution pattern of the CO model from vehicles from the level of congestion.

Published: December 2021

Abstract
Demands for building in urban areas have been increasing lately, especially educational buildings as support for the human development index. Unfortunately, only a few educational buildings can support green buildings as pilots and educational materials for their users. One of the initiators in becoming educational materials and examples of green buildings is the i-cell multipurpose educational building at the Universitas Indonesia. This study aims to find evidence of how reliable and sustainable planning of an educational building in Depok, Indonesia, can accommodate the needs of its users while being environmentally friendly for its surroundings. It observes the influences of vegetation in the surrounding building, one of which is by maximizing the function of vegetation around the building. The research methods include collecting data from the weather archive, vegetation literature, observing the subject, and analyzing the vegetation’s effect. This study shows that vegetation has an important role in generating a sound environment for humans and buildings, including healing and providing calmness. This study concludes that vegetation plays a role in generating a good environment by decreasing temperature, sound pollution, sun glare and providing shading areas for people. Those conditions lead to the sustainability of the environment surrounding the building.

Published: December 2021

Abstract
This article discusses the implications of the emergence of platform work as a form of precarious work that threatens Indonesia’s target to meet Goal 8 of SDGs. Despite the work platform providing employment opportunities to many workers, most work in the non-standard employment (NSE) category. This means that they work precariously due to insufficient work protection, which may lead to severe consequences to decent work and productive work as critical elements of Goal 8 of SDGs. This research aims to assess the implementation gap Indonesia faces in realizing the roadmap of Goal 8 of SDGs. Using the qualitative descriptive research method, the authors analyzed and explained the challenges through comparative data study from 2016 to the year 2020, with emphasis on four main area indicators of Goal 8 of SDGs. We concluded that promoting precarious work in Indonesia might hinder the implementation of the 8th goal of SDGs on decent work. We offer some policy alternatives to mitigate the challenges by underlining the importance of new regulations to extend job protection to all workers regardless of the employment relationship.

Abstract
Strategy to achieve food security is crucial for all countries around the world. This becomes more important for Indonesia as the fourth most populous country. This study evaluates Indonesia’s agricultural sustainability as one of the food security programs. In specific, the evaluation is based on micro-economics point of view by analysing the financial performance of the agricultural industries. This study also examines the role of ownership and external auditors as corporate governance instruments controlling a company achieving its ultimate objective. Conducting a quantitative study and examining Indonesia listed companies for the period of 2003-2018, the results show that most of Indonesia’s listed agricultural companies are not sustained as they were in bankruptcy zone. The ability of companies to manage the costs and commitment to do investments create value for the future, and the role of foreign ownership as one of governance instruments is found to be able to prevent agricultural companies from bankruptcy. The findings bring practical implications on the importance of financial literacy for managers of agricultural industries and good corporate governance practice to ensure the sustainability of agriculture.
