Over the past few decades, cities have experienced severe social and economic pressures, which have a disproportionate impact on the urban environment. As a result, the quality environment has decreased, which is characterized by increased CO2 emissions and energy operating costs. Sustainable city development is considered as a step to create a pleasant environment for the community. Therefore, this research is essential to do to regenerate settlements in improving urban quality. This study aims to find a model for developing sustainable hybrid settlements in densely populated areas. The research method with the simulation method uses the Urban Modeling Interface device with three parameters. The modeling results obtained a Floor Area Ratio (FAR) value of 0.43 with a total land area of ± 427,233 m2. The FAR value produces an operational energy value of 3,983kwh / m2 / year and an embodied energy value of 216 kWh / m2 / year. This value is very high from 240 kWh / m2 / year as a standard for energy use. The amount of mobility in the aspect of walkability is 21-68, and 21-69 for the value of Bikeability. The results of this simulation indicate that the residential area in Jatinegara is not yet sustainable.

The expansion of land development for settlement and other infrastructure has impact for lessen of green open space that serves to absorb rainwater. Accordingly to that, there is a need of effort to increase the absorbtion rate of rainwater into the ground; one of the methods is using biopori holes. The area that uses as a sample to observe the infiltration rate using biopori holes is Kopelma Darussalam, Banda Aceh. The aim of this study is to measure the infiltration rate before and after the application of biopori holes, find out the amount of holes that required, discover the differences of ground water level every 2, 5, and 10 years return period and find out the amount of water that absorbed to ground water. The data which uses to calculate the water level is the annual maximum daily rainfall, land area under forest cover and texture, and infiltration rate. Meanwhile, the data which uses in order to calculate the volume of water infiltrated into the soil in each month is monthly rainfall data, land area which classified by the cover and texture and infiltration rate. Inundation height at annual maximum rainfalll plan for 2, 5, and 10 years return period with using 100, 160 and 400 holes for each 100 m2 is lower from 9.01% to 77.43% compared to not using biopori holes. In addition, the amount of water that infiltrated after using biopori holes is increasing up to 4120 m3 for each month.

作者： Ratih Widiastuti Chely N. Bramiana I.R.H Bangun Bintang N. Prabowo Mirza Ramandhika Architectural Study Program Vocational School Diponegoro University Semarang Indonesia Department of Architecture Faculty of Engineering Diponegoro University Semarang Indonesia

During the last decade, greenery aspect in the building envelope starts to increase their presence in the building design. Vertical greenery system became the one of alternatives that potential to energy-saving in the building. However, in tropical area, researches related to vertical greenery system are enigmatic since reducing heat in tropical area are crutial for maintaining space in comfort condition. In this study, a comparative thermal analysis between green facade and green wall will present. A model called house miniature set up with climbing plans as model of green facade. While for green wall, data measurement was conducted in the office building with green wall as building envelope. The results showed a high potential for energy savings during peak time in the afternoon for green wall (1.5%) and green facade (1.3%) in comparison to the bare wall. While for interior facade are 2.6% for green wall and 2.2% for green facade. Effect of vertical greenery also found in the outdoor air temperature around greenery system. Results show at the hottest time of the day, the green wall and green facade reduced outdoor temperatures by 3.0°C and 1.2°C, respectively. Based on the analysis, compared to green facade, the cooling effect produced by green wall is faster. Possibility, the substrate properties in the green wall also help to decrease temperature. The reduction can be due to the foliage density as the leaves of green wall is denser than leaves in green facade.

Human-wildlife conflict has been one of the most trouble-causing issues in many areas of Nepal including Eastern Nepal. This study assessed the human-wildlife conflict status in Paschim Kusaha Village of Koshi Tappu Wildlife Reserve(KTWR), Sunsari District, Nepal. Data were collected from 47 respondents of different households through questionnaire surveys and formal and informal interviews. Results revealed that the most destructive wild animals were wild elephants, wild boar,and wild water buffalo and the most raided crops were paddy(63.83 %), maize(19.15%), and potato(17.02%). Most of the encounters between humans and wildlife were recorded at night(after dusk and before dawn)(78.72%). Local people were suffering from damage of physical properties, human harassment or nuisance, and depredation of cropland due to wild animals.A total of 70% of respondents had a positive attitude towards conservation despite disturbing human mortality records(22deaths in the last five years) from the reserve area and surrounding. Awareness of wildlife behavior together with conservation and easy access to compensation schemes were suggested to minimize conflicts in the area.

Recent studies have shown the potential of zinc oxide as an additive in diesel engines because of its favorable properties. Goethite, as a metal additive, exhibits good thermodynamic stability and acts as a catalyst carrier to reduce environmental pollution. Incorporating zinc oxide microparticles and goethite nanoparticles into pure palm oil (PPaO) has great potential to improve the fuel properties. Therefore, in this study, the effects of adding zinc oxide microparticles and goethite nanoparticles into PPaO on the engine performance, spray characteristics, and smoke opacity of a diesel engine were investigated. A high-speed camera was used for the spray experiments. The results showed that the use of PPaO significantly increased the smoke opacity by similar to 127.89 % compared with diesel fuel (DF). However, the use of PPaO with zinc oxide microparticles (PPaOZnO) and PPaO with goethite nanoparticles (PPaOGOE) significantly reduced the smoke opacity. The reduction in smoke opacity was most pronounced for the PPaOGOE fuel blend, with a value of 60 %, relative to the smoke opacity for DF. The PPaOZnO fuel blend significantly increased the specific fuel consumption by 37.1 %, with an average increase of similar to 24.21 %, compared with DF at an engine load of 40 %. Moreover, the use of PPaOZnO and PPaOGOE fuel blends improved spray penetration 2 times compared to PPaO, although the relative viscosity and spray angle were similar to those for PPaO. These findings suggest that zinc oxide and goethite have great potential as additives for PPaO fuel, thereby enhancing the efficiency and performance of diesel engines.

We report the nanoconfinement-mediated graphitic nanoporous carbon nitride (gNPCN) adsorbents with a high content of inbuilt basic nitrogen (N) (48%) by X-ray photoelectron spectroscopy (XPS) for efficient CO2 adsorption. The gNPCNs (gNPCN-150 and gNPCN-130) are synthesized using the mesoporous SBA-15 silica template and a single carbon-nitrogen (C-N) precursor (guanidine hydrochloride). The various adsorbents were utilized for investigating the influence of pore size (PS), surface area (SA), and type of adsorbent for CO2 adsorption performance. The capacity for CO2 capturing of gNPCN-150 reached 23.1 mmol/g at 0 degrees C under 30 bar pressure. This CO2 capturing capacity value was higher than the capacity gNPCN-130, SBA15, activated carbon (AC), and multiwalled carbon nanotube (MWCN) under identical conditions. The gNPCN materials exhibited superior CO2 adsorption ability that is ascribed to the presence of the highly organized mesoporosity, inbuilt high content of basic N site for adsorbing more CO2 through acid-base interaction, and tunable surface-structural properties. Moreover, the synthesis strategy is remarkably flexible in selecting C-N sources. This study features graphitic high-ordered nanoporous CN materials as a resourceful platform towards the efficient CO2 capture.
