Authors: Santoso Kahfi Ridho , Hidayat Irpan , Suangga Made 
Published: March 2020

Abstract
When an earthquake occurs, ductility will maintain strength and stiffness in the structure so that the building structure still works even though it is on the verge of collapse. To get a description of the structural behavior starting from the structure in linear elastic, the first yielding of the structural elements until the structure collapse due to earthquake load, it can be done with non-linear static analysis namely pushover analysis. In this study, the geometry of mid-rise reinforced concrete structure consists of four storey buildings. The dimensions of the column structure 400x400 mm and beam structure 250x500 mm, where the dimensions of the beams and columns are the same from the 1st floor to the 4th floor. To find out the behavior that affects the ductility value in mid-rise reinforced concrete structures, a variation material used in this study are the spacing of stirrup, ratio of longitudinal reinforcement, ratio of compressive and tensile longitudinal reinforcement, and compressive strength of concrete. Structural geometry modeling, structural loads, and modeling of material variations used the program SAP 2000. From the output of this program, an analysis of the value of curvature ductility and displacement ductility was performed. The result of this study are the higher the value of compressive strength of concrete and the ratio of longitudinal reinforcement in beam structure will increase the value of ductility. The smaller the value of the spacing of stirrup and the ratio of longitudinal reinforcement in column structure will increase the value of ductility.

Abstract
Stability is a parameter that reveals the extent of decomposition of biodegradable organic matter. Various methods are employed to measure the stability level of organic materials, including the static respiration index (SRI) and dynamic respiration index (DRI). In this study, the characteristics and stability of food waste, garden waste, municipal organic waste, fruit waste, tofu factory waste, and cow dung samples used in the study were identified and analyzed on the basis of the water content, volatile solids, C/N ratio, lignin content, and SRI and DRI values. In addition, an appropriate method for the further processing of unstable organic waste samples was determined. Organic waste samples were collected from nine places. Results revealed that the tofu factory waste samples exhibit the highest SRI and DRI values of 13.3995 mgO2g−1OM−1h−1 and 148.3747 mgO2g−1OM−1h−1 respectively. The composting results for tofu factory waste samples and cow dung with coconut shells as the bulking agent for 14 days revealed that the highest percentage of SRI decrease for tofu factory waste was 99.94% on the 3rd day of composting. On the other hand, the highest percentage of SRI decrease for the cow dung samples is 99.17% on the 7th day of composting.

Abstract
The collapse of the structural component of a building can cause physical and material losses, both to the building management and the building’s occupants. This can happen due to the absence of a standard operating procedure that is appropriate to the government’s regulation regarding the maintenance and care for structural components. In the current condition, the government’s building as the center of public services does not have a proper standard operating procedure regarding the maintenance and care for structural components. The aim of this research is to develop a procedure regarding the maintenance and care of a building’s structure based on risk. Risk in this context is defined as the risk that influences the duration of each work activity. The methods used in this research are archive analysis, survey, and case study. The result of this research is a standard operating procedure for maintenance works and care for structural components of a building based on risk. This can be utilized to increase the efficiency and effectiveness of the work process.

Abstract
One of the largest and busiest ports in Indonesia that handles more than 30% of Indonesia’s non-oil and gas commodities is located in Tanjung Priok. The purpose of this research is to analyze the noise level and compare it with the noise level standard by Ministry of Environmental regulations No. 48/11/1996 and analyze the noise levels from traffic activities in JICT I. The primary noise level data of Leq (Equivalent Noise Level) on sampling points number 9 at JICT I area was taken using the Sound Level Meter. Secondary data includes the schedule and type of incoming ships, as well as the JICT I Tanjung Priok Port layout. Sampling data was taken during 24 hours activities, which on daytime for 16 hours (06.00-22.00 WIB) and night time for 8 hours (22.00-06.00 WIB). The results showed a high level of noise almost occurred at all points, especially at night and the peak appeared on Saturdays which was with a noise range of 83-85 dB (A). The main noise source is caused by truck and container loading and unloading activities. Therefore, the conclusion is the noise level caused by JICT I Tanjung Priok activites has exceeded the noise level standard by Ministry of Environmental regulation No. 48/11/1996 and by Jakarta Governor’s Regulation No. 551/2001 which was 70 dB(A). The vehicle speed restriction and replacement of crane engine from diesel to electric has been implemented. However, it still have not been able to reduce the impact of the noise. An alternative that can be applied is to use a sound barrier or the construction of Onshore Power Supply (OPS).

Abstract
It is desirable to have pavement surfaces that last until its designed life. Ravelling, rutting, and potholes are one the pavement failures that are commonly found and those failures are related to the intrusion of moisture onto the asphaltic mixture. This research aims to study the usage of hydrated lime as an additive to improve the moisture susceptibility of the asphaltic mixture. There were two different natural aggregates used in this research project and the prepared specimens were tested by Marshall, Cantabro Loss, and Indirect Tensile Strength tests. From the research results, it was found that hydrated lime was effective in not only improving the moisture susceptibility of the asphaltic mixture, but also increasing the stability and making the asphalt specimens denser. It was also found that it is critical to choose the suitable aggregate to be used in the asphaltic mixture as it can significantly affect the quality of the asphalt specimens.

Abstract
There are a large number of people in the world who live without an adequate supply of clean water, and spend hours to get clean water. For this reason, access to water and water sources is one of the main keys to meeting the needs of the community’s clean water, specifically rural communities in the semi-arid regions of Indonesia. This study aims to analyze the extent to which access to clean water sources affects the patterns of water use and fulfillment of rural communities. The method used is a survey completed with a questionnaire and observation. The object of the research was the rural water user community in TTS Regency, East Nusa Tenggara Province with a total of 87 families, and water sources in the study area. Samples were divided into three areas which were categorized as dry, normal and wet. based on the analysis of rainfall data at 14 rain stations. The results showed an average water use level of 49 Lpcd (SD = 25) and the distance to the water source as far as 521 m (SD = 1100). There is a negative correlation between the distance of the water source and the amount of clean water used. Water availability factors affect water usage more than long distances but can be reached. This study also found that the use of clean water by the community is adaptive to the availability of water according to environmental conditions. This study recommends the importance of handling clean water issues according to the characteristics of each different region.

Published: March 2020

Abstract
This paper presents modelling of the progressive failure of steel moment frames subjected to localised fire. A finite element approach using the software ABAQUS has been developed to analyse the structure. An explicit-dynamic solution was adopted to solve the non-convergence problems caused by element buckling. A series of validation analyses were carried out to ensure that the results were within an acceptable level of accuracy. The analysis results are shown to match well with the previous experimental data and analysis. This modelling approach allows detailed insights to be obtained into the structural robustness of such frames in fire situations.

Published: March 2020

Abstract
Increasing the volume of cars passing through local roads in residential areas and the various dimensions of concrete speed bumps made by citizens for safety, makes it important to conduct research on the correlation of car speed and the variables that influence the presence of speed bumps. The variables used are speed variables, dimensions of concrete speed bumps and road shoulder width. The speed variable used is the speed of the car before crossing the speed bumps with the help of an artificial line on the video or vehicle recording results. From the analysis of car speed before passing concrete speed bumps, it was found that speed bumps can reduce speeds by 80.17%. The car speed reduction model is Y2 = 12,762-0181 X2 + 0.114X3. Y2 = speed at a distance of 16 meters before speed bumps, X2 has wide speed bumps (cm) and X3 is the average width of the shoulder (m), and R2 is 0.970. This model applies to the condition of the dimensions of the width of the speed bumps 32.6 - 57 cm and the shoulder width of the road 30 – 100 cm.

Authors: Aryo  , Suangga Made 
Published: March 2020

Abstract
Various structural systems have been developed to be able to accept the lateral force of the earthquake with an optimum and economical. One of these structural systems is the outrigger system. Outrigger is one of the structural stiffening systems that can be used on building structures, especially in high-rise buildings. Structural systems such as outriggers are used for earthquake-resistant buildings, so the performance of building structures can be increased by producing minimum displacement. This research will design the building as high as 40 and 50 floors, with the calculation of earthquake based on Indonesia Earthquake Design Code SNI 1726-2012. This study will be compared the calculation of seismic loads in the building structure with and without using outrigger, so that it can be seen the difference in the seismic loads and the performance of the structure. From this research, it is found that the outrigger system can reduce the seismic loads in the structure, and also is able to reduce the lateral displacement of the structure. The inter-story lateral displacement of 50 storey and 40 storey structure can be reduce up to 2.06% and 7.84% with one outrigger and 3.76% and 12, 49% with two outrigger.

Published: March 2020

Abstract
The Javan leopard is an apex predator with a key role in maintaining the stability of the ecosystem, in which it’s population are declining due to habitat loss, illegal wildlife trade, and human-animal conflict. Although efforts in rescuing Javan leopards are actively made, not all rescued Javan leopards can be released back to the wild. Some must go through rehabilitation process in captivity, due to physical injuries. One issue regarding leopards in captivity is the risk of them developing stereotypical pacing, a repetitive stereotypic behaviour due to stress in confinement as one of the sign of zoochosis. Zoochosis itself is a mental illness in animals. Zoochosis will definitely interfere with the success of rehabilitation process. Therefore, cases of zoochosis such as in zoos must not occur in rehabilitation facilities. A further understanding of animal’s needs and behaviour is needed and must be implemented in the design of the enclosure. Not only to prevent zoochosis, but also to improve and promote the natural behaviour of the Javan leopard. This study aims to analyse how the design of an enclosure correlates to Javan leopard’s behaviour. Through methods of observation and evaluation of rescued Javan leopards at a rescue center in Sukabumi, by studying the overall facility design and the behaviour of the leopards. Results shows that the rescue center enclosure provide more natural environment with live foliage, sunlight, minimal noise disturbance, hiding spots, and able to simulate hunting behaviour during feeding time. The leopards housed shows no significant sign of zoochosis.

Published: March 2020

Abstract
Humans have tendency to relate to nature. This is a human trait inherited from generation to generation. Where we can feel happy, interested or amazed by the beauty of nature. The rapid development and technological advances make our relationship with nature farther away. As a result, we become indifferent to the environment around us, the degeneration of ecosystems, and cause mental disorders and stress. Stress and stress disorders are problems that are often experienced by office workers in big cities like Jakarta. There are 60.8% of office workers experiencing depression and stress. One factor causing stress is the work environment, which is a dense urban area. Therefore, rebuilding our relationship with nature becomes more important in the field of conservation. The concept of biophilic design is a design approach based on biophilia aspects which aims to produce coworking spaces that can reduce stress and provide mental and physical healing to its users.

Published: March 2020

Abstract
The Central Jakarta area is the largest contributor to retribution for DKI Jakarta, and most of its population expenditure is in the food sector. The need for a new culinary center that can become a new communal space for urban communities requires a design approach that supports the creation of sustainable architectural designs in terms of social aspects. The application of the concept of threshold space is done through qualitative design methods in designing culinary centers in Palmerah - Central Jakarta that provide and sell food and drinks. The design of this culinary center is expected to become a new communal space that functions as a recreational space and a space for social interaction that functions well. Threshold space concept was chosen to be applied in the design because it functions as a transition space that connects one function to another, so that integration between spaces is also well created.
