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.

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.
由于土地危机和人口密集，非正规住区面临厕所设施不足和粪便污泥堆积率高的卫生挑战。然而，无论哪种方式，那些在非正式生活中挣扎的定居者都能设法保持厕所的运转。这项研究探讨了非正规住区居民的粪便污泥管理实践。它以Notun Bazar Char Khulna为例，有目的地对厕所和人口进行采样，并在定居点人员、清洁工、关键人员之间进行访谈和小组讨论，并对定居点进行详细观察。它还在图纸和图表中绘制了排泄物的流量和排泄位置。它说明了所有类型的安全壳中的粪便污泥是如何进入水中的是不安全的。本研究分析发现，在非正式定居点中，与定期遏制管理、集体排空机制和粪便污泥有条件输送有关的做法是可行的。它建议在非正规住区发展环境安全的粪便污泥管理，并对已确定的做法表示赞赏。

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.

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.
土地利用变化检测通常用于批判性地识别趋势、原因及其对景观的影响，以加强保护生物多样性和生态功能的决策。本研究的目的是评估1986年至2017年喀麦隆Tubah分区土地利用和土地覆盖的变化，并确定不同土地利用地区的植物多样性和丰度。为了确定该地区的多样性，在4个不同的地点建立了8个50 × 50米的样地，采集了直径为胸高(胸径≥10mm)的乔灌木。主要数据是通过实地观测和地面查实获得的，以便确认卫星图像上的观测结果。利用GIS ArcGis 10.2制作土地利用图。提取了1986年、1996年、2006年和2017年的图像。共录得植物173种，隶属于63科146属。休耕地和次生林的香农指数最高，分别为3.09和2.97。农牧地多样性最低，H′= 1.39。GIS数据分析显示，1986-1996年植被覆盖减少90.24 ha, 1996- 2006年减少23.76 ha,2006 -2017年减少86.70 ha。1986-1996年，居民点面积增加了63.64 ha, 1996-2006年增加了53.37 ha, 2006-2017年增加了15.36 ha。水体从1986-1996年减少了7.34公顷，从1996-2006年减少了14.28公顷，从2006-2017年减少了3.56公顷。1986年至2017年，裸地面积增加了135.88公顷。实地观察表明，农业集约化、建筑、不可持续的伐木和放牧是影响Tubah分区植物多样性的主要原因。这项研究的结果对于未来的土地使用规划工作和长期保护社区的生物多样性和水源至关重要。应该对图巴的人口进行可持续土地利用管理和生物多样性保护方面的教育。

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.
农村地区的废物管理问题不同于都市地区。未经管理的废物有可能危害农村环境。了解家居及与家居有关的废物的产生及特点，是规划废物管理的起点。准确测量废物的产生和特性有助于优化减少废物和回收工作。因此，本研究旨在使用印度尼西亚国家标准19-3964-1994方法测量农村地区的废物产生和特征。调查小组连续8天访问了丹戎沙里街道60个住宅和非住宅物业样本。根据研究结果，产生的废物量为0.34 kg人-1天-1。有机废物(食物垃圾、树叶、纸张和木材)占垃圾的大部分(81.34%)，其次是无机材料(塑料、织物、其他材料、金属和玻璃)，分别为15.66%、1.86%、0.91%、0.12%、0.11%。生活垃圾密度为196.1 kg m-3，非生活垃圾密度为63.63 kg m-3。家庭规模和收入、生活习惯以及发展的经济或工业类型都影响着农村垃圾的产生和构成。农村废物管理战略需要考虑将有机废物作为堆肥或发酵的原料。

Bagelen and its surrounding area are parts of the Kulon Progo Hills which have less water potential. However, groundwater can still be obtained from dug wells or several springs in the hills. This study aims to determine the quality of groundwater in the study area as clean water and drinking water. Hydrogeological surveys have been conducted to see the quality of this groundwater. Groundwater samples were taken from six dug wells and two springs. Groundwater can be found in sandstone, limestone and andesite breccias aquifers, through intergrains and cracks porosities. Groundwater usually has Ca-bicarbonate facies. The need for good quality groundwater for drinking and clean water has been investigated based on the WQI value. The WQI value is determined based on several physical parameters, including turbidity and TDS and chemical parameters such as pH, Fe, hardness, Mn, nitrate, Zn, sulfate, chloride and sodium. Based on the Minister of Health Regulation standard No. 492/2010 for drinking water and No. 32/2017 for clean water, the groundwater showed good - excellent value for drinking water and excellent value for clean water.

Participants in scientific conferences have been traveling to the cities of conference venues. These mobilizations left carbon footprints due to carbon dioxide (CO2) emissions generated from the scientists' transportation to their conference venue. This study looks at the carbon footprint of scientists who attended scientific biodiversity conferences in Indonesia from 2015 to 2019. We have identified that 30 scientific biodiversity conferences were conducted in 17 cities on five different islands during the corresponding period. The conferences have published 3092 scientific articles written by 9617 authors from various disciplines. The estimated carbon emission due to those scientists' transportation was 622 tons CO2-eq. This emission figure is almost equivalent to the emission produced by a person circling the earth 91 times using a passenger aircraft. A new paradigm of virtual conference should be considered to minimize the carbon footprint resulted from the scientists' transportation to and from the conference venue. Thus, the CO2-eq emissions released by scientists' transport can be reduced significantly. These emission reductions may mitigate and minimize the magnitude and impact of climate change to some extent.

The need for built-up areas continues to increase, along with the increasing population in the city of Surakarta and its surrounding. This condition affects the land surface temperature which then leads to the change in climatic conditions. The availability of land for settlement and surface temperature will affect the comfort level of living in a city. For this reason, this study aims to map the distribution of built-up area and the surface temperature of Surakarta city and discusses the relationship between these two aspects spatially and temporally. The data used are Landsat imageries recorded in 2000, 2013, and 2019. The built-up area was identified using Normalized Difference Built-Up Index (NDBI), while the temperature data was obtained through thermal band processing using Land Surface Temperature (LST) method. The results showed that during the period of the study, the built-up area and the surface temperature in Surakarta and its surroundings increased, especially in the eastern and southern parts of Surakarta. The results also showed that there is a positive correlation between the built-up index and its surface temperature.

This condition affects the land surface temperature which then leads to the change in climatic conditions. The availability of land for settlement and surface temperature will affect the comfort level of living in a city. For this reason, this study aims to map the distribution of built-up area and the surface temperature of Surakarta city and discusses the relationship between these two aspects spatially and temporally. The data used are Landsat imageries recorded in 2000, 2013, and 2019. The built-up area was identified using Normalized Difference Built-Up Index (NDBI), while the temperature data was obtained through thermal band processing using Land Surface Temperature (LST) method. The results showed that during the period of the study, the built-up area and the surface temperature in Surakarta and its surroundings increased, especially in the eastern and southern parts of Surakarta. The results also showed that there is a positive correlation between the built-up index and its surface temperature.","PeriodicalId":22187,"journal":{"name":"Sustinere: Journal of Environment and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44432540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genuk District is a residential development area which has a role as a Semarang City's transportation hubs. It is directly adjacent to Demak Regency and the Java Sea. As of the time of writing, Genuk District has a population of 117,174 people with the total of 130.88 m³ waste transported to the landfill each day and the percentage of waste transportation services in the area is 38.53%. The waste transportation average operational time is 0.2 hours exceeding the amount of working time with the number of 17 trips/day. This planning aims to arrange the waste transportation system in Genuk District by taking into account the traffic congestion in order to get the optimal operational time and costs. Arm roll truck vehicle operating costs in the existing conditions in 2020 was IDR 1,347,411,591.00, while in the optimized condition would be IDR 1,341,405,786.37. Meanwhile, dump truck vehicle operating cost in the existing conditions in 2020 was IDR 302,002,441.00, while in the optimized condition would be IDR 278,453,956.22. The operational time for waste transportation should be started at 06.00-15.00. After optimization, the average remaining working hours becomes 2.68 hours per day with a vehicle's speed of 57.11 km/hour. The planning for waste transportation system optimization will reduce the retribution costs by IDR 900.00 and increase the percentage of waste transportation services to 53%.

The purpose of this study is to evaluate Corporate Social Responsibility (CSR) programs for local communities around mining companies in Kalimantan, Indonesia, based on environmental, economic, and social perspectives. We create evaluation criteria consisting of; six on the environmental perspective, three on the economic perspective, and two on the social perspective. CSR reports are collected from the company website. Each company was given a score based on whether these evaluation criteria were present (1) or absent (0). The evaluation scores of the CSR mining companies programs’ in Kalimantan, Indonesia are high in considering cleaner production, waste reduction, material flow management, and recycling, committed to managing energy and water, developing infrastructures surrounding mining companies, has good corporate ethics, and encourages employees to volunteer for social causes and provides incentives for these activities; medium in committed to following all applicable laws and policies concerning environmental standards and policies, committed to conserving biodiversity, committed to managing sound and vibration from mining activities as well as protecting the air quality around the mining area, and enhancing self-employment options for local communities; low in taking long-term factors into accounts, such as global climate change and other environmental threats, and providing jobs opportunities for local communities. From the evaluations above, access to information, public participation, and transparency in discussing areas of corporate-community issues are all things that mining companies must improve. If there is a lack of congruence between aim, activity, and effect, civil society organizations should frequently criticize mining companies' CSR operations.
