Authors: Putra Andi Bayu 
Published: March 2020

Abstract
Construction Services Laws are legislation used to govern all manners of construction services. This research was taken in Jakarta, Indonesia. Laws used in this research are Law Number 18 of 1999 about Construction Services and Law Number 2 of 2017 about Construction Services. With the shift of Construction Services Law, of course there are several differences, changes, revision, and inclusion and exclusion of past laws. This changes and differences were analysed to improve the current running Construction Services Law for the future. This research uses two methods, which are literature study and study using questionnaire through observations and interviews. Variables and questions for the questionnaire were formed from study of literature, past researches and Construction Services Laws discussed in this paper. Results from the questionnaire was analysed using a computer program, IBM SPSS Statistics 23. Using that program, the data from the results were tested for its validity and reliability. And it was analysed using correlation analysis and factor analysis. From the analysis it was concluded that there are two factors that needs to be improved, the two factors are: regulation about building failure is not explained well enough, and the lack of regulation about Expert Assessor. Through these results, the construction services law can be improved and prevent environmental health damage caused by building failure that was caused by problems in construction services. These environmental health damage caused by building failure have negative impact to environmental health and safety of the surrounding area, whether from emission or toxic pollutants.

Published: March 2020

Abstract
Adaptation to the concept of sustainability is a problem in developing countries, especially in terms of the level of knowledge, economic capability, environmental conditions, and regional policies. These four aspects become exogenous variables in this study to examine the role of green building concepts in sustainable concepts in building construction. Qualitative and quantitative methods become a way to prove the hypothesis of this study by using SEM-PLS as an analysis tool. The sample in this study limits the building developers and owners to assess aspects that affect the sustainability of the green building concept and obtain an overview of the incentive models they expect. The results of this study indicate the level of knowledge of building developers and building owners affects the ability of building management to achieve a sustainable concept. Besides, the aspect of sustainability has an impact on the acquisition of both internal and external incentives for developers and building owners. Specific incentive models that developers and owners expect are accelerating licensing and building certification and reducing property tax. The government also supports the provision of property tax compared to value-added tax because it is a controlling tool in implementing green building concepts.

Published: March 2020

Abstract
The developers of residential areas generally promote a theme in marketing their residential units. Likewise, one of many developers in West Jakarta markets its residential area with the Green theme. The purpose of this study is to identify the application of the green architectural design concept in building design and neighborhood at residential area. This research uses descriptive method through survey and field observation. The results showed that almost all criteria of the green concepts have been applied on building design and neighborhood with classical modern style related with theme of the cluster. The criteria are Appropriate Site Development, Energy Efficiency and Conservation, Water Conservation, Indoor Health and Comfort, and Building Environment Management. The use of renewable local materials (bamboo and wood) is not widely applied in home design. But the selection of modern materials follows the green standard, which is material that is already eco-material certified. The supply of building materials also comes from the area around the housing, so it does not use a lot of fossil energy.

Abstract
Collaborative arm robot is a robot that can work alongside humans. By using force limiting (FL) feature, where the force of the arm robot is limited and controlled, the robot can sense collision and stop its movement when it occurs. The idea is to apply the mentioned concept for service purposes. In this research a 6-axis arm robot with collision detection is developed. The design of the arm robot adopted the design of Universal Robot’s UR3 with each joint capable of 360° rotation. The design approach is chosen for its flexibility to work in tight space with a maximum reach of half meter, as it is intended to work closely with human. This initial version robot is not intended to carry heavy load or move at high precision. With a maximum load of one Kg, this arm robot targets numerous applications that help human to do complex repetitive tasks, extend the reach of human operators, and help humans on many daily chores that usually does not involve heavy loads. The whole frame, which also serve as the cover of the robot, was made by 3D printing with multiple materials that fit to the strength and temperature requirement at each part of the robot. In order to detect collision, the arm robot employed smart servos at each joint with the ability to detect overcurrent and overvoltage, which allow the implementation of force limiting (FL) feature that will stop the robot in case of collision. The resulting arm robot managed to lift1 kg load and able stop its movement in the event of collision. Future research to improve the movement precision of the arm robot by adaptive methods is promising.

Abstract
With the increasing global demands of coffee, Indonesia need to increase their coffee beans supply and improve the quality to maintain its position in the international coffee industry. One of the most important coffeepre-processing, coffee bean roasting, is under developed in Indonesia. Indonesia coffee farmers prefer to use the traditional cauldron to roast their coffee beans. Roasting coffee beans using traditional cauldron is inefficient and resulting unequal roasted level for the coffee beans. In this study, we proposed atemperature control system based on fuzzy logic for coffee roaster machine. The system controls the temperature in accordance with the demanded roasting level. A thermal camera is attached inside the roasting chamber to monitor the heaton the roasted coffee beans. The thermal camera is integrated with a stirring mechanism to equalise the heat among the beans.

Abstract
This project presents the implementation of green productivity methodology for furniture industry. The main issue in furniture industry is reducing environment pollution and industry waste. The objective of this study is ti apply and implement the green productivity methodology in furniture industry to carry out the environment and waste problems. The green productivity utilizes three tools, specifically material balance, eco-mapping and plant layout. Through the analysis results of material balance, the majority of production wastes were sawdust and a small piece of woods that cannot be exploited again. Instead of being burned, it will be preferable to be accumulated and sold it at the market. With eco-mapping analysis, it can be recognized about which area that produced the most substantial amount of wasted pieces. Hence, the remaining of sawdust will also be collected to be sold. After that, the proposal of the plant layout has been established with the consideration of production scheme and also the distance between all stations will be closer than before. The plant layout chosen is the first of proposed plant layout because it has the shortest production flow distance, which is 49,5m, which can intensify the efficiency of 160% from the original layout. Besides of the reduction industrial waste of this workshop, the company productivity is increased and obtained the additional income as a consequence of invaluable waste at first, to be processed to gain value-added.
