Abstract

This research aims to develop a prototype IoT-based water flow sensor to monitor water flow in real-time. This prototype uses micro-scale water flow sensor technology that is sensitive and efficient in energy use. It combines it with an IoT-based wireless communication module to send water flow data to the server. The data obtained from these sensors can then be accessed and analyzed via the web or mobile application. This prototype also incorporates a monitoring element, where users can monitor water flow remotely via a mobile or web application.

Abstract

PKS PT. Torus Ganda Tambusai Timur, located in Tambusai Village, Tambusai District, Rokan Hulu Regency, is a palm oil factory that produces Crude Palm Oil (CPO) with a production capacity of 60 tons of FFB per hour. The processing processes at this PKS include weighing, boiling, pressing, pulverizing, refining, and extracting the core at PKS PT. East Tambusai Double Torus, the Sterilizer used is a Horizontal Sterilizer, which has an elongated cylinder shape and is positioned horizontally using lorry transportation to transport fresh fruit bunches. The boiling process uses saturated steam with a three-peak boiling system. This research aims to determine the efficiency of the hydraulic pump needed to move the actuator on the Sterilizer door at PT. East Tambusai Double Torus. The object of this research is the Horizontal Sterilizer at PKS PT. East Tambusai Double Torus focuses on determining the efficiency of the hydraulic pump needed to drive the actuator on the Sterilizer door and maintaining the hydraulic pump. The conclusion of this research shows that maintenance is essential in a factory because it helps manage company expenses. After observations and discussions, the efficiency of the hydraulic pump in moving the actuator on the sterilizer door was obtained at 86%.

Abstract

This study aimed to calculate the volume of air required by a blower to transfer tapioca flour from the dryer unit to the shifter unit in a factory with a production capacity of 35 tons per day. The flour transfer process utilizes a blower to generate sufficient airflow. Still, it often experiences instability caused by factors such as blower speed fluctuations, material load variations, and pipe blockages. The research was conducted over one month using data collection methods that included interviews and direct observation. Analysis results showed that the cross-sectional area of the blower pipe was 0.6358 m², the airflow velocity was 1.517 m/s, and the airflow rate reached 0.965 m³/s. The total air volume required by the blower to move the flour was calculated to be 27,792 m³ per day. The findings highlight the importance of properly regulating and maintaining the blower system to ensure efficiency in tapioca flour production.
