Exploring Opportunities of Adopting Biophilic Cities Concept into Mixed-Use Development Project in Malaysia
Authors: Arof K Z M , Ismail S , Najib N H , Amat R C , Ahmad N H B 
Published: January 2020

Abstract
Mixed-use development project in urban area emerged to cater the increase of population in the region. Due to rapid urbanisation, many research recommended the engagement of human with nature in cities development, including the mixed-use development project since nature and human are holistically created to complement each other. This is where the United Nation (UN) under its sustainable development programme has established 17 development goals that amongst all cover both sustainable cities and communities. This shows the urgency of having cities that best fit human nature. However, although many mixed-use development projects were constructed with senses of nature, many of these projects are harmful to environment as they are unable to sustain the natural habitat as well as human needs. Hence, there are many attempts to connect human with nature in Malaysia via sustainable cities and green cities concepts although no specific guidelines on these have been established. Recently, emerged the term biophilic cities, a new concept combining sustainable and resilient cities, which are also seen as the panacea to these mixed-use development project issues despite the efforts done via the former concepts of sustainable and green cities alone. Generally, biophilic cities resemble green cities with a few enhanced greener criteria that affiliate human to nature as opposed to green and sustainable cities that merely bring nature to human. Therefore, this paper aims at investigating the elements of biophilic cities that can be adopted for mixed-use development project in Malaysia. Via systematic literature review, this paper listed the criteria of biophilic cities from previous studies, which are then used in designing the questionnaires distributed to 173 construction players in the mixed-use development projects in Malaysia. It is found that biophilic cities encompass four main criteria that are important to be adopted in mixed-use development project in Malaysia, namely “building”, “block”, “street” and “neighbourhood”, with a total of eight design elements. As biophilic cities are closer to human needs and environment whilst able to manage the rapid urbanisation and increased world population that is meant to be tackled by the mixed-use development project, construction players should start to consider adopting the biophilic cities concept in their mixed-use development project in Malaysia.
Space Compatibility Based on Spatial Behavior of Street Vendors in Urban Public Space in Chinatown, Semarang
Authors: Widjajanti R , Damayanti M 
Published: January 2020

Abstract
Street vendors grow rapidly in Asian developing countries, including in Indonesia. They grow massive and uncontrolled in the urban public spaces, causing loses on the public spaces’ main function. Furthermore, waste from the street vendors’ activities causes environmental degradation and urban aesthetic reduction. Eviction and relocation are usually done by the government to overcome the problems. The government evicted and moved the street vendors to another place as planned. Street vendors’ relocation often did not succeed because they always return to their original places. The indication is the street vendors felt uncomfortable in the new location or the new location was incompatible with their activities. Until now, the government has not been able to provide the proper location for the street vendors. The study of compatible space for the street vendors is an urgent matter because the study of the street vendors which have been done so far was more focused on aspects of social, economic and political/policies. This study aims to identify space compatibility based on the spatial behavior of street vendors at their activity's location. This research used the descriptive quantitative method with questionnaires and Geographic Information System (GIS) as a tool to map the street vendors’ location. The results showed the compatibility space of street vendors based on the type of neighborhood activity, type of activity around public spaces, neighborhood activity time, numbers of visitors, visitor movement patterns (flow of visitors and visitor activities) and spatial patterns.

Abstract
Characteristics of granitic igneous rocks as a source of tin mineralization in the study area are generally ilmenite granite series or commonly called Granitic S type. The occurrence of rare earth elements is relatively common in the earth’s crust. Based on its chemical properties, the occurrence of REEs (Rare Earth Element) is rarely scattered and not concentrated in one place, so it is often stated that it is not economical to be mined. However some rare earth mineral deposits such as monazite can be processed economically. Rare earth element like monazite is discovered as by-product from mining process and extracting tin mineral. The purpose of this study is to examine the separation process of tin ore that could affect the grades of tin ore produced. The highest grade of pure tin obtained rare earth element and will be optimal to the ore extraction. The methods of concentrating monazite use wet processing followed by dry concentration techniques, then extraction and refining are required. This method was observed during the study. The result showed that extraction involved sulphuric acid routes and the acidic route is the most common, dominating at least 90% of the current extraction methods.

Abstract
Hydrogeological conditions can provide information on movement and groundwater conditions, which have a significant influence on mining activities, especially underground mining. Research using geo-electric has been applied in various fields. This study aims to analyze the distribution of aquifers in the Sekotong area and provide basic planning tools to regulate underground mining in NTB Province. This study uses a geo-electric survey to assess hydrogeological conditions in underground mining by using the specific vertical electric sounding (VES) of Schlumberger array method, with 3 points (BP 01, 02, and 03). The output from the geo-electric survey shows that the apparent resistivity curve is being checked using IP2Win software. The results of this study indicate the value of the resistive type is between 3 - 25 Ωm; it can be concluded that the aquifer layer is at a depth of 1.5 m to 60 m. However, from data analysis, it was shown that the study area was formed by half of the tuff layer and cracked breccias. Therefore, below 60 m depth, it is indicated that permeable layers formed by volcanic breccia and lava are present.

Abstract
The development of concrete technology in infrastructure also triggers the progressive cement manufacture, where cement production also contributes significantly to the emission of CO2. To minimize the use of cement and increase mortar quality, the addition of additive substance material is needed with a quality control method. The purpose of this research is to establish the proportions of the materials with the optimum partial replacement of cement by silica fume to the compressive strength and physical properties of the 56 days old mortar using Taguchi Method design of experiment. This research uses 3 factors, which are silica fume proportion, sand proportion, and cement proportion. Each factor consists of 3 levels, with silica fume content is ±20% from the total weight of the cement. The mortar is based on 9 combinations of materials on the orthogonal matrix L9(34) created with dimensions of 50 x 50 x 50 mm cube. The results show that the optimum proportion is 150 gr of silica fume, 660 gr of cement and 1400 gr of sand which is equivalent to replacing 18.52 % cement with silica fume, which gains 54.00 MPa compressive strength, pH 9.75 and 5.369 % water absorption.

Authors: Rahmawati D , Adiansyah J S 
Published: January 2020

Abstract
The gold mining sector in Indonesia consists of large-scale gold mining, medium-scale gold mining, and small scale gold mining. Small scale miners generally use mercury amalgamation method to extract gold as it is considered as the most efficient method and requires only a small investment. The utilization of mercury might affect environmental quality and human health. This study is aimed to evaluate the possible remediation technology for mercury-contaminated sediment. A case study from Sekotong Sub District was carried out due to the operation of small scale mining in this area. The qualitative method was used by using a literature review approach. Various technologies of mercury remediation were explored and compared. The results indicated that there were 12 available technologies associated with mercury sediment handling. Those technologies include dredging, in-situ thermal desorption, capping, activated carbon, solidification, and nanotechnology. The appropriate technology is determined by some aspects, including mercury intensity, technology effectivity, and cost. In addition, the application of those technologies requires a social license to operate not only from the community but also from the government as a regulator.

Published: January 2020

Abstract
Central Lombok Regency has a potential for non-metallic mineral and rock mining. This study aims to map the distribution of non-metallic mineral and rock mining locations and analyze the suitability of the location distribution with space allocation neighborhood and community unit in Central Lombok Regency. The research uses descriptive analysis method and map overlay. The results show that the location of non-metallic minerals and rock mining is spreading in seven sub-districts in Central Lombok Regency, namely Pujut, West Praya, Southwest Praya, Kopang, East Praya, North Batukliang, and Pringgarata. The distribution of mine sites reaches 49 points. Based on the results of the overlay of the mine location map with the spatial planning map, there are several mines located in the watershed (river border area) and the distance is close to residential areas. Thus the government needs to formulate a policy to provide limits to the development of a mining area. The southern part of Central Lombok Regency is developed as a special area of national tourism. The government must consider this situation to make sure the development of the mining area does not interfere with tourism development.

Published: January 2020

Abstract
One of the artisanal mining locations in West Nusa Tenggara Province is Pelangan Village, Sekotong Sub-district, West Lombok District. There are two main activities in the artisanal mine site, namely mining operations and material processing, that commonly use logs and mercury (Hg). This study aims to determine the effect of differences in log spacing from mercury content in well water at Pelangan Village, Sekotong Sub-district. This study uses the Cross-Sectional research method to obtain an overview of mercury levels in the Pelangan Village of Sekotong Sub-district based on distance and to determine the differences in variables using Chi-Square statistical test. The results showed that 46 water wells had mercury levels less than 0.001 mg/l and 8 water wells had mercury levels more than 0.001 mg/l. From the results of chi-square analysis, the Pearson Chi-Square value was 6.541 with df = 1 and a significant value less than 0.05. The Chi-Square value concluded that there is an effect between the distance of the log and the mercury content of the community water well. To avoid the mercury pollution, three strategies should be applied including distance of water well from the pollution source should bigger than 95 meters, the best distance, and replacing mercury with something that more environmentally friendly.

Published: January 2020

Abstract
Frequent mining activities cause environmental damage. Pumice mining at Ijobalit village left holes from the previous mining activities. These holes become barren land that ruined the scenery, however, this problem can be solved by reclaiming the former mine ares. Reclamation transforms the areas into a tourism area. The transformation of the former mine area into tourism object, however, did not last long as the Lembah Hijau tourism attraction no longer has activitiesand seems to be not taken good care of. This research aims to determine the development strategy of the Lembah Hijau Tourism object that exists in the former mine area. The research method used is a qualitative descriptive using SWOT analysis by viewing from external and internal instruments. The results showed that the tourism area in the former mine area has good natural potentials, the lakes formed from the former mine have theirown appeal. The weaknesses lie on the accessibility, lack of cooperation among private sector, the government and the community, and also lack of promotion and innovation of attractions.

Published: January 2020

Abstract
The existence of mining activities is aimed at improving the welfare of society, especially the mine circle society. Mining activities have been changed based on the three parameters of sustainable development, i.e. economic, social, and environmental. On the economic and social parameters, they have interactions that have a potential impact on influencing the change of mine circumference behavior which is closely related to the existence of the mine circle society itself. The methodology used in this study is the literature review based on existing studies and a brief observation around the mine. The observation technique is carried out by a random selection of respondents (random sampling) with a confidence number of 95%. The analysis results show that there are three types of behavioral changes that occur, namely natural change, planned change, and willingness to change. The factors influencing the behavioral change in the community around the mine areas, especially external factors, are education, religion, culture, environment, and socio-economic. The behavioral changes and factors affecting these changes can be used as a foundation for a mining company to develop community empowerment programs as part of good mining practices. The good mining practices will facilitate the mining company to get a social license to operate.

Abstract
Mining material of quarry (class-C) as one of the activities that utilize natural resources should be able to bringgood impacts to the community economy, but with the understanding of the community that is still said to be low. Some factors such as economic impetus, ignorance aspect, personal interests, political elements, the usage, the quarry brings more negative impact. This is due to the fact thatthere are no clear rules and no boundaries in operatingthe mining process. Reclamation is very difficult to do. The purpose of this research is to explain to the community ofthe dangers posed byquarry to the environment of thecommunity forest at Karang Sidemen Village North Batukliang District, Central Lombok. This research uses qualitative method of research and uses three methods of data collection, namely observation method, interviews, and documentation conducted in the village. This research uses four stages of data analysis, namely data collection, data reduction, display or presentation, and data verification. Theresults show that the understanding of the people about the dangers of class-C mining to the environment of the community forest in the village of Karang Sidemen is still low, due to low education level and based on economic drive factor.
