Authors:Jussac Maulana Masjhoer, Syafrudin Syafrudin, Maryono Maryono Pages: 174 - 184 Abstract: Waste management issues in rural locations differ from those in metropolitan ones. Unmanaged waste has the potential to harm the rural environment. Understanding the generation and characteristics of household and household-related waste is the starting point for planning waste management. Accurate measurement of waste generation and characteristics helps optimize waste reduction and recycling efforts. Therefore, this study aims to measure the waste generation and characteristics in rural areas using the Indonesia National Standard 19-3964-1994 method. The survey team visited 60 samples of residential and non-residential properties in the Tanjungsari Sub-district for eight consecutive days. Based on the results, the waste generation was 0.34 kg person-1 day-1. Organic waste (food waste, leaves, paper, and wood) accounts for the majority of garbage (81,34%), followed by inorganic materials (plastic, fabric, other materials, metal, and glass) at 15.66%, 1.86%, 0.91%, 0.12%, 0.11% respectively. The residential waste density is 196.1 kg m-3, while in non-residential areas is 63.63 kg m-3. Family size and income, living habits, and the type of economy or industry that develops have influenced the rural waste generation and composition. Rural waste management strategies need to consider organic waste as a raw material in composting or fermentation. PubDate: 2023-03-28 DOI: 10.22515/sustinerejes.v6i3.246 Issue No:Vol. 6, No. 3 (2023)
Authors:Rahmawati Fitria, Henita Rahmayanti, Bagus Sumargo Pages: 185 - 196 Abstract: Flooding has been a recurrent problem in the Indonesian capital, especially in the northern part of Jakarta, along the Jakarta shore. The floods were caused by a number of sources. According to Renald et al. (2016), there are four critical factors in designing disaster-prone cities in Indonesia, namely spatial management, disaster adaptation, disaster mitigation, and technology innovation. Therefore, the development of infrastructure in Jakarta has started to use these four elements, by applying the concept of environmentally friendly drainage, specifically the concept of eco-drainage. This study aims to understand the general picture through the cause-and-effect relationship between all flood components. This study used a qualitative approach and was conducted using a dynamic system method to describe the Causal Loop Diagram (CLD) model, which provides information between interrelated variables and forms a complex system Rifaldi et al. (2021). The model generated from the dynamic system can be used for scenario analysis by showing how the interactions between the components that make up the structure of the system and the effects of feedback loops affect. The CLD model shown shows that the use of eco-drainage will directly affect the condition of 2 (two) other variables, both of which will lead to one main variable. The proposed settlement scenarios will result in policy and technical recommendations. This CLD model shows that the interaction between variables is very dynamic and affects each other massively and holistically. Combining dynamic system processes with SMWW can potentially improve the expected results in engineering and provide an alternative scenario.

Authors:Abu Towab Md. Shahriar, Kh. Mahfuz-ud- Darain Pages: 197 - 213 Abstract: Informal settlements suffer sanitation challenges of inadequate toilet facilities and a high accumulation rate of faecal sludge due to land crises and dense populations. However, settlement people who struggle with informal living, either way, manage to keep their toilets running. This research explores faecal sludge management practices by people in informal settlements. It took Notun-Bazar Char Khulna as a case, purposefully sampled toilets, and populations, and conducted interviews and group discussions among settlement people, sweepers, key persons, and detailed observations of settlement premises. It also mapped excreta flows and discharge locations in drawings and diagrams. It illustrates how faecal sludge from all types of containment ending in the water is unsafe. This study analytically finds practices related to periodical containment management, Collective emptying mechanism, and faecal sludge’s conditional conveyance available in the informal settlement. It suggests developing environmentally safe faecal sludge management in informal settlements with an appreciation of the identified practices.

Authors:Septianto Aldiansyah Septian, Randi Adrian Saputra Pages: 214 - 226 Abstract: Designing an industrial location must be based on consideration of factors that will influence it such as natural, environmental and ecological conditions. One of the spatial-based location determination methods is Spatial Multi-Criteria Evaluation (SMCE). This study aims to determine suitable industrial areas and compare industrial locations that have been determined based on the Regional Spatial Plan (RTRW) for 2010-2030 in Kendari City. Industrial areas must be flood-free, located in a relatively flat area, far from settlements, have good access and must not interfere with the river’s natural function. Therefore, the aspects of access, hydrology, physiography and convenience were all taken into account in this study. The area in Scenario A was retested with Scenario B and Scenario C to get a variety of industrial areas with different perspectives. Kendari City’s appropriate industrial area is 2.462.36 ha and is located in Puuwatu Sub-District, which is directly connected to Mandonga Sub-District (scenario 2.C). The RTRW map with the industrial model of the area shows the mismatch of the proposed industrial area placement. The results of this industrial area can be used as an alternative for decision-makers.

Authors:Amelia Choya Tia Rosalia, Tri Mulyaningsih Pages: 227 - 238 Abstract: Countries all over the globe are facing climate change. Global warming is a real problem that occurs and affects food production. Precipitation and temperature rise are causes of the changes observed in this study. This study examines the relationship between food security level due to climate change. To provide further clarity, a systematic literature review (SLR) towards the impacts of climate change was conducted to identify the extent of its impacts on food security and to identify the extent of its impacts on the level of food security and research gaps. This systematic review identifies and analyzes documents on the impact of climate change on the level of food security in terms of the impact of climate change, the methods used to analyze climate change, and the available climate change adaptation policies. Following SLR guidelines, Google Scholar is the main database. This research can broaden our knowledge about the impacts of climate change and the role we can play in maintaining food security.

Authors:Hening Tyas Subekti, Joko Christanto Pages: 239 - 250 Abstract: Previous studies found a reduction in pollution levels when travel was banned due to the COVID-19 pandemic. This study aims to identify the changes in community mobility and air quality, as well as to analyze the effect of community mobility changes on air quality during the early phase of the COVID-19 pandemic. This study used daily secondary data from Google Mobility Report and station data archive of Air Quality Monitoring System (AQMS) which records Air Pollutant Index Standard (ISPU). This study focused on the early phase of the pandemic (15th Feb – 15th June 2020) in six provinces in Java and Bali. This study used panel regression and GIS. The results show that there is 35-90% reduction in mobility and also some decreases in air quality pollutants. Furthermore, it was shown that there is a positive relationship between ISPU and mobility. Community mobility explains ISPU in Bali, the Special Region of Yogyakarta, the Special Capital Region of Jakarta, West Java, Central Java, and East Java by 24%, 53%, 13%, 3.7%, 20%, and 39% respectively. Meanwhile, the combined influence of the six provinces is 18.8%. The variable that has a significant effect is the community mobility changes on transit stations. Every 1% increase in the transit station's mobility is capable to increase ISPU by 0.4. PubDate: 2023-03-28 DOI: 10.22515/sustinerejes.v6i3.219 Issue No:Vol. 6, No. 3 (2023)
Authors:Awo Miranda Egbe, Fonge Beatrice Ambo, Angwi Judith T, Tabot Pascal Tabi Pages: 251 - 270 Abstract: Land use change detection is often conducted to critically discern trends, causes, and their impacts on the landscape to enhance decision-making for conservation of biodiversity and ecological functions. The objectives of the study were to evaluate Land Use and Land cover changes in Tubah Sub-Division, Cameroon, from 1986 to 2017, and to determine plant diversity and abundance in areas with different land uses. Field surveys were carried out to determine the diversity of this area, eight 50x50m sample plots were established in four different sites and trees and shrubs with diameter at breast height (DBH≥10mm) were sampled. Primary data was obtained through field observations and ground truthing in order to confirm observations on satellite images. Land use maps were produced using GIS ArcGis 10.2. Images were extracted for the years 1986, 1996, 2006, and 2017. A total of 173 species were recorded in all the sites belonging to 63 families and 146 genera. The fallow land and secondary forest were the most diverse of all the sites with the highest Shannon index of H′= 3.09 and H′= 2.97 respectively. The least diverse were the agricultural and grazing lands, with H′= 1.39. Analysis of the GIS data revealed a decline in vegetation cover of 90.24 hectares from 1986-1996, 23.76 ha from 1996-,2006 and 86.70 ha from 2006-2017. Settlement areas increased by 63.64 ha from 1986-1996, 53.37 ha from 1996-2006 and 15.36 ha from 2006-2017. Water bodies reduced from 1986-1996 by 7.34 ha, 14.28 ha from 1996-2006 and 3.56 ha from 2006-2017. Bare ground increased by 135.88 ha from 1986-2017. Field observations revealed that agricultural intensification, construction of buildings, unsustainable logging and grazing were the major causes affecting plant diversity in Tubah Sub-Division. The study’s outcomes are critical for future land-use planning exercises and the long-term conservation of the biodiversity and water sources for the communities. The population of Tubah should be educated on sustainable land use management and biodiversity conservation. PubDate: 2023-03-28 DOI: 10.22515/sustinerejes.v6i3.253 Issue No:Vol. 6, No. 3 (2023)
