PENGEMBANGAN PROTOTIPE ALAT UJI PERMEABILITAS BETON BERPORI UNTUK MENENTUKAN KOEFISIEN PERMEABILITAS
Full text linkThe increasing growth of infrastructure and building development has led to a reduction in land surface cover. The lack of surface cover significantly impacts the environment, such as causing severe flooding. To address water-related issues, one approach is to manage runoff at its source through Low Impact Development (LID) strategies, such as permeable pavements. One method used to infiltrate water is porous concrete. Key parameters of porous concrete include strength, water-cement ratio, porosity, and permeability coefficient. The permeability coefficient of porous concrete is obtained through permeability testing. Laboratory permeability tests are more commonly used than field-testing. Therefore, it is important to have a dedicated tool for testing the permeability of porous concrete.
The first stage involves the development and testing of a prototype, which includes prototype design, material survey, material procurement, equipment preparation, prototype construction, and testing. The prototype development refers to the ACI 522R-10 standard. The results of the prototype testing are analyzed using Darcy’s law to determine the permeability coefficient and analyze the flow characteristics.
Based on the research findings, the permeability test prototype for porous concrete can be used as a testing tool for porous concrete permeability both in laboratory and field settings. The prototype exhibits laminar flow, thus allowing Darcy’s law to be applied for evaluating hydraulic conductivity

Full text linkMetode HIRA (Hazard Identification and Risk Assessment) adalah sebuah metode atau teknik untuk mengidentifikasi potensi bahaya kerja dengan mengklasifikasikan karakterisitik bahaya yang dapat terjadi dan mengevaluasi risiko yang terjadi melalui penilaian risiko dengan menggunakan matriks penilaian risiko. Pekerjaan kolom beton merupakan salah satu pekerjaan yang memiliki risiko tinggi terhadap kecelakaan kerja yang meliputi pekerjaan pembesian, pekerjaan bekisting, pekerjaan pengecoran, dan pekerjaan pelepasan bekisting. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan pendekatan studi literatur tanpa observasi langsung ke lapangan. Berdasarkan analisis risiko kecelakaan kerja pada pekerjaan kolom beton di Proyek X hasil rekapitulasi menunjukkan bahwa rata-rata nilai risiko pekerjaan kolom beton secara keseluruhan berada pada angka 9,8, angka tersebut menunjukkan bahwa sebagian besar risiko berada pada kategori sedang hingga tinggi
Prototype of Electrical Power Breaker Automation ON PHB-TR Using Microcontroller-Based IOT For Flood-Prone Areas
Full text linkThe flood disaster caused losses for PT PLN consumers whose areas were flooded. To prevent electric shock accidents due to flooding, PT PLN took steps to extinguish distribution substations whose areas were affected by flooding. This step was taken to maintain the safety of the flood-affected community from being electrocuted, but this resulted in a loss for PT PLN, namely the selling kWh that was not distributed. In this study, the method used is research and development, where the author makes an idea to overcome the problem of the length of power outage due to flooding by making a PHB-TR Control Prototype for Distribution Substations. Where this prototype is an innovation to replace the main switch on the PHB-TR with MCCB and MCB which are applied in the box panel. With this prototype, PT PLN officers can speed up the process of blackout areas experiencing flooding quickly by controlling the MCCB and MCB at the PHB-TR distribution substation from the PLN office, but still maintaining the reliability of the 20 kV Medium Voltage Network. This prototype is based on the Internet of Things that can be controlled remotely using the Blynk application that can be operated from smartphones and computers. This prototype design is expected to help PLN officers to cut off the PHB-TR load from the PLN office or remotely, as well as some of the benefits that PT PLN can receive from this tool innovation, namely saving kWh that is not channeled and a positive image for PT PLN will be maintained by maintain the reliability of the electrical distribution system

Optimisation of Energy Consumption Balance in Multi-Hop Topology Wireless Sensor Networks for Environmental Monitoring Systems along Railway Tracks
Full text linkThe implementation of IoT requires careful planning so that the system can function optimally. This study describes the planning of WSN development as a network in an IoT system with a long, straight topology, such as that found on railway tracks. The planning includes the use of appropriate technology with minimal power consumption. Three simulation scenarios were conducted using LPSAN, LPWAN, and a combination of both to compare their performance on a straight-line topology. The profile of each technology in LPSAN and LPWAN in terms of their performance in transmitting sensor data in the IoT system will be determined. The network lifetime performance is also determined to demonstrate the energy efficiency of each technology. Thus, the most optimal scenario in terms of configuration and topology in a straight-line network will be selected. From the experiments conducted, it is concluded that multihop topology is generally recommended for use in straight-line networks compared to star topology, except in conditions where nodes are very close to the gatewa
