The method used is Research and Development (R&D) with prototype development method. This application is designed to facilitate project management in monitoring, reporting progress and bookkeeping of construction projects. Testing is done in two ways, namely blackbox …
ABSTRACT The dissemination of information related to mosque da’wah activities—such as religious lecture schedules, event registration, and general announcements—is often done manually through social media. This process typically takes about 2–3 minutes daily and may lead to delays or errors in communication. To address this issue, this study aims to design and develop a mosque da�…
ABSTRACT Leakage in water pipe systems is a critical issue that must not be underestimated in terms of its handling and resolution. If pipe leaks are not addressed promptly, they can lead to adverse effects such as decreased water flow efficiency and, in some cases, complete interruption of water distribution. Therefore, a water pipe leakage detection system is essential for residential applic…
ABSTRACT This study discusses the design of a Solar Power Plant (PLTS) to support the operation of fish ponds using a biofloc system in Kampung Pangan Madani. The system consists of five catfish ponds with a capacity of 1,000 fish each and one gourami pond with 250 fish, requiring a total daily energy consumption of 6.6 kWh. The analysis was conducted using PVSyst simulation software on three …
ABSTRACT Syafira Hospital Pekanbaru was originally established as Syafira Clinic in 2006, now handling an average of 3,200 patients per month with a total of 12 polyclinics. Limited land has led to the use of the road shoulder as a parking lot, long parking duration and ineffective management, which leads to traffic congestion. The methods used in this study include parking accumulation survey…
ABSTRACT Asphalt mixtures in Indonesia consist of three types, Asphalt Concrete (AC), Hot Rolled Sheet (HRS), and Stone Matrix Asphalt (SMA). The main difference among these mixtures lies in the aggregate gradation. Generally, asphalt roads are constructed using Hot Mix Asphalt (HMA), which produces relatively high CO₂ emissions during the heating process, contributing to ozone layer depleti…
ABSTRACT Propylene glycol is one of the organic compounds commonly used as a food preservatives, cosmetic raw materials, wetting agents for chewing gum, monomer in the synthesis of polyester, and anti-freeze liquids. The demand for propylene glycol is increasing along with the development of the industry, especially the cosmetics and textile industries. The market value of propylene glycol glo…
ABSTRACT Indonesia has exported ten shipments of acetophenone through three suppliers to several countries, including China, Japan, and Singapore. However, since domestic production is still insufficient to meet demand, Indonesia still needs to import acetophenone from several countries. This situation presents a significant opportunity to establish a plant to meet domestic demand while compet…
ABSTRAC Indonesia still imports from various countries due to domestic supply shortages. The global acetophenone market was valued at US$ 219 million in 2021 and is expected to grow rapidly from 2022 to 2032. This situation presents a significant opportunity to establish a factory to meet domestic demand and compete with international producers from China, India, and Germany. The demand for ac…
