Abstract

One of the methods of applying lean construction in the construction sector that shifts from traditional to lean, eliminating all activities that do not generate added value, is supply chain management. This research compares the supply chain in two projects to decide on added value projects. This stems from the efficiency of establishing a simple organizational structure and encouraging contractors to focus more on the dominant material work. Supply Chain is a systems approach to delivering products to end consumers by using information technology and coordinating with suppliers and manufacturers/producers. The supply chain comparison for the second project is more inclined to the project apartment because it has four patterns and does not have much organizational coordination. In the apartment project pattern, the main contractor focuses on the project's core and provides activities to support subcontractors, such as elevator work. MEP work on buildings is complex, especially in coordinating the procurement of equipment, materials, and human resources because it involves many people and organizations both from outside and in the implementation process. Supply chain management in the construction sector is an effort to improve performance. To be more effective and efficient in providing high competitiveness for other contractor companies.

Abstract

Construction projects frequently encounter supervision and control challenges, leading to delays and cost overruns, primarily due to inadequate information management. This study examines the impact of Information Management Systems (IMS) adoption on project supervision and control in Banda Aceh, with a focus on information quality, technological readiness, and user competency. Using a quantitative survey of 95 construction professionals and multiple linear regression analysis, the findings reveal that IMS enhances real-time data accessibility, transparency, and process integration. However, its effectiveness depends on technological infrastructure, user training, and management support. These insights offer strategic recommendations for optimizing IMS adoption to improve project performance.

Abstract

Asphalt concrete layer (laston) has a high degree of flexibility so that placing it directly on top of layers such as AC-WC (Asphalt Concrete – Wearing Course) makes this layer vulnerable to damage due to high temperatures and heavy traffic loads. The type of damage that often occurs in the laston is the release of granules and cracks. Styrofoam is a type of plastic polymer that is thermoplastic when heated it becomes soft and hardens when cold. When mixed with gasoline, styrofoam will soften and can function as an adhesive. This study was to determine the value of Marshall characteristics in the addition of styrofoam into the asphalt.variations used for styrofoam content are 1%, 1.5%, 2% with asphalt content of 4.5%, 5.0%, 5.5%, 6.0%. The results showed that the optimum asphalt value was obtained at 6% asphalt content. And the mixture that meets the requirements is the addition of 1% styrofoam. Higher content of styrofoam will reduce the value of the melt (flow) and will reduce the value of Marshall stability.

Abstract

Jolotundo is a village in the Mojokerto Regency area that is located on the slopes of Mount Penanggungan, close to the forest and Majapahit kingdom relics. In Indonesia, public awareness of the importance of health is declining, causing bad behavior and unhealthy environmental conditions in the community. As technology advances, health technology such as orgonite becomes an effective method of treatment or restoration for both physical and psychological health. Unfortunately, no facilities provide a place to support this method. Therefore, it is necessary to have a facility that provides a place of recovery within the orgonite method based on healing and negative energy elimination for physical, mental, environmental, and spiritual well-being. This research employed field studies and literature studies as well as several methods such as observation, documentary, and interview to obtain data, both primary data as a direct data source and secondary data as other supporting data sources. The design applies the theme of therapeutic architecture, the macro concept of tropical architecture, and the micro concept of adaptive land use. The design environment involves green open spaces and maximizes landscape arrangements.

Abstract

Aluminium foil waste increases every year in line with technology development, especially in the food and beverage industry. It will cause significant environmental problems because the packaging cannot be destroyed in the soil. Therefore, it is necessary to reprocess a large amount of aluminium waste into an alternative product such as alum which can be applied directly to the treatment of liquid tofu waste. In this study, uncoated aluminium foil waste was used, which was taken at random landfill sites and then washed and cut into small pieces. Dissolution of aluminium using KOH solution then the solution obtained is reacted with H2SO4 solution and the reaction is carried out at a temperature of 70oC. The experimental results got a maximum yield of 63.69% with Al2O3  content of 15.18% using 3 M KOH concentration and 5 M H2SO4 concentration. The obtained alum was then applied to the tofu industrial liquid waste. With the use of 800 ppm alum, there was a 60% decrease in the colour content of the Pt-Co unit, a 95.8% decrease in NTU and a 63.33% decrease in TDS. The quality of the liquid waste obtained met the technical requirements of raw water that can be treated by SNI 6773: 2008.

Abstract

One of the control problems that is a challenge for an engineer and the chemical industry itself is chemical processes which are closely related to nonlinear processes. The linear method is the choice for many researchers to overcome problems in nonlinear processes, namely the linearization technique. This causes uncertainty whether the controller is able to work on the actual nonlinear process. The purpose of this study is to integrate Aspen Plus Dynamics and Matlab Simulink to eliminate linearization in order to be able to control nonlinear processes optimally. The method used is to perform steady state and continued dynamics simulation in the case study of the deisobutanizer distillation. Then integration of Aspen Plus Dynamics with Matlab Simulink using AMSimulink. The results show that steady-state and dynamics simulations have been successfully carried out. Aspen Plus Dynamics and Matlab Simulink are integrated and able to run together. The controllers used include reflux drum level control, top column pressure control, and reboiler level control. The response results obtained in the co-simulation run well, the process response can perform setpoint tracking.

Abstract

AK-Tekstil Solo is a vocational campus with several workshops for lectures, one of which is the Spinning and Weaving Workshop. It has yarn and fabric manufacturing machines and holds the most significant electricity consumption for machine operations, lighting, and other instruments. Hence, a smart workshop room with electrical energy efficiency is crucial. This research aims to design and develop a smart workshop lighting system using an Arduino-based microcontroller circuit and photocell components. The light intensity setting system is performed by determining the measurement point of light intensity and measuring the natural and artificial light intensity as the input for photocell and relay. An automated lighting system for the smart workshop was then developed using a photocell censor based on the Arduino Mega microcontroller. Product testing shows that the automatic switches and relays based on programming successfully work the automated system.
