ABSTRACT Micro, Small, and Medium Enterprises (UMKM) in the culinary sector face challenges in production efficiency due to the limitations of the equipment they use. Many business owners still rely on manual methods or simple machines that are unhygienic, inefficient, and difficult to clean. To address these issues, this final project aims to modify a manual meat grinder into a motorized syst…
ABSTRACT Hydrological analysis requires input from various data to be able to perform a good analysis. One of the most important data to be used in hydrological analysis is rainfall data. Rainfall is an important parameter to estimate the water available for plants and also to determine the hydrological quantities to be used. Rainfall data in a watershed can be used in various fields. In this …
ABSTRACT Prof. M.Yamin, S.H. Bangkinang Road is a national road that connects Riau province and West Sumatra province. This road is the main access connecting the Bangkinang Kota District with Pekanbaru City before the construction of the Trans Sumatra toll road in section XIII Koto Kampar - Bangkinang - Pekanbaru. This is marked by the presence of heavy vehicles t…
ABSTRACT The use of natural fibers as an alternative textile material is growing along with the increasing need for environmentally friendly and sustainable materials. One of the potential natural fibers is pineapple leaf fiber (Ananas comosus), which has a fairly high tensile strength. This study aims to examine the effect of variations in alkalization treatment using sodium hydroxide (NaOH) …
ABSTRACT Pipes are widely used for the transportation of liquids from one place to another, commonly found in domestic and industrial areas. Piping systems are becoming increasingly important for energy supply, economic activities, industry, the social sector, and other aspects of life in most countries because they are widely used for the distribution of water, oil, gas, and others. Pipeline …
ABSTRACT The attendance system is a crucial component in the administrative activities of educational institutions. SMA Negeri 6 Tualang still uses a manual attendance system, which presents several drawbacks such as the potential for fraud, inefficiency, and vulnerability to data loss. This research aims to implement a student attendance system based on face recognition and geofence technolog…
ABSTRACT Fire disasters cannot be predicted in terms of time and location, therefore an early warning and response system technology is needed. This study aims to design a prototype system based on the Internet of Things (IoT) in the event of a fire in a room. There are several features in the system design consisting of a microcontroller (ESP32) connected to three sensors: flame sensor (5…
ABSTRACT Pedestrian Overpasses (JPO) are essential facilities designed to ensure pedestrian safety when crossing roads, particularly on sections with heavy traffic flow. However, in the city of Pekanbaru, the utilization rate of pedestrian overpasses remains relatively low. This study aims to evaluate the performance and utilization level of pedestrian overpasses based on the 1995 Bina Mar…
ABSTRACT Piping systems are an important element in the distribution of fluids in various industries, such as drinking water, oil, and gas. However, pipes often suffer damage due to natural disasters, corrosion, mechanical failure, or other external factors. This damage can take the form of leaks, blockages, or pipe ruptures, which can cause injury, damage to facilities, environmental pollutio…
ABSTRACT Energy at this time has a very important role in human life. So far, the main support for energy needs still relies on petroleum, while it is inevitable that petroleum is increasingly scarce and expensive. With the depletion of fossil energy sources, in today's world there is a shift from the use of non-renewable energy sources to renewable energy sources. Of the many renewable energy…
ABSTRACT This study demonstrates that the Artificial Neural Network (ANN) algorithm can effectively adapt to varying operating conditions, both under Standard Test Condition (STC) and under dynamic irradiation and temperature scenarios. The simulation was conducted using MATLAB/Simulink, modeling a PV power system comprising a Trina Solar TSM-250PA05A.08 solar panel, a boost converter, and a l…
ABSTRACT Regional development in a region will cause the need for air to continue to increase along with population growth. Understanding future clean water needs is crucial, including the availability of raw water sources and clean water service facilities to ensure the community's clean water needs are met. This study analyzes and predicts the future demand for and availability of clean wate…
ABSTRACT Environmental conditions such as temperature and humidity significantly affect the growth and health of broiler chicks. Inappropriate environmental parameters can lead to stress and higher mortality rates. Therefore, a system that can monitor the poultry house conditions in real time is essential. This study aims to design and develop a temperature and humidity monitoring system for b…
ABSTRACT Ammonia is a raw material in fertilizer production. Ammonia is produced by reacting synthesis gas containing H2 and N2 with a ratio of 3: 1. Synthesis gas contains inert gases that do not react such as Argon, in addition to H2 and N2. H2 gas comes from hydrocarbons found in natural gas and N2 gas from free air. Natural gas used as raw material for production before being processed int…
ABSTRACT Fatty alcohol is a high alcohol compound (aliphatic class) that has a chain length between C8 and C32 that can be produced from animal fat or vegetable oil. Fatty alcohol is generally used in emulsion and micro-emulsion products, for example in cosmetic products, detergents, and personal care products. Indonesia has continued to import fatty alcohol for the past five years with an ave…
