Abstract

A safety instrumented system (SIS) is specifically designed to protect personnel, pieces of equipment, and the environment by reducing the likelihood or severity of the impact of identified emergency events. This review has five objectives, i.e., (i) to find the layers of protection, (ii) to figure out and implement the SIS through life cycle step design, (iii) to find the Safety Integrity Level (SIL), (iv) to find the Safety Requirement Specification (SRS), and (v) to figure out and think about the SIS design that will be used. The study's methods are algorithms that a researcher uses to carry out research in stages of achievement and accordance with research objectives. Referring to the review proposed, five results have been achieved, which are guided by the process stages. The SIS design has been implemented and can be used as a reference for understanding the basic concepts and instrumentation of process control systems. The second is figuring out and implementing the SIS, which is an essential stage in the life-cycle step process. The third, the SIL determination, can be done using qualitative or quantitative methods that involve evaluating two risk components, e.g., probability and severity, and lies in the risk levels and the weighting structure. Furthermore, a matrix shows many of the factors that are used to determine the SIL levels. Fourth, the SRS consists of two parts, i.e., requirement specification of the functional and the integrity. Fifth, one of the considerations in designing the SIS is the separation between the SIS and the BPCS, thereby reducing the possibility of both systems failing simultaneously. Finally, the consequences range from minor injury to high death, and the main conclusion in this article is that the concept system will make it easier to find references or get predictions for determining instrumentations and creating a process control system.

Abstract

The raw salt should be reduced the size to convert it into consumption salt. Salt crushing machine generally was designed to reduce salt grain size using rollers for crushing. The small-capacity salt-crushing machine should be designed to meet the needs of small businesses. This study aims to design a salt-crushing machine in a small capacity with a proper power transmission system that will be applied to a roller-type salt crusher. The transmission system is designed to upgrade the performance of roller-type salt crushers through V-belt and pulley transmission mechanisms and obtain the appropriate size or type of V-belt and pulley based on the capacity of the drive motor. The results show power required to crush salt by this system is 299.46 W. The motor used is a single-phase AC motor that has a power size of 1/2 HP, and the corresponding v belt is type A with a size of 51 inches, the rpm needed is 360 rpm, and the distance between rollers is 0,7 mm. Then the pulley needed is with a ratio of 1: 4. The pulleys used are type A1 which has a diameter of 3 inches and 12 inches. The average salt weight loss after the crushing process was 14.27%.

Abstract

BaP (Benzo[a]pyrene) is one of the Polycyclic Aromatic Hydrocarbon (PAH) compounds produced from the combustion process of organic materials such as wood husks. This study aims to utilize the MQ 3 sensor integrated with RobotDyn Uno R3 WiFi microcontroller to measure BaP concentration in gas emissions from wood husk combustion. The MQ 3 sensor was chosen for its sensitivity to BaP compounds. In this experiment, the MQ-3 sensor achieved an accuracy of 85% with a BaP measurement range from 0 to 26 ppm. Measurements were conducted on wood husks with BaP concentrations varying from 0 to 4 ppm. The results indicate that this method is effective for real-time monitoring of BaP levels in wood husk combustion processes, with potential applications in controlling toxic gas emissions from such processes

Abstract

The refining process of sugar cane juice includes a crucial stage termed carbonation, which is pivotal for achieving pH balance through the utilization of carbon dioxide (). The need for is fulfilled by burning biomass, including rice husks and sugarcane bagasse. However, this process can generate hazardous compounds, notably Formaldehyde (), posing significant health risks. To address elevated Formaldehyde concentration, a monitoring system is implemented, employing an MS1100 sensor for real-time monitoring within the carbonation tank. The data is transmitted to a web-based platform via Robotdyn Uno Wi-Fi R3, with direct data storage on a micro SD card to ensure persistence even during Wi-Fi disruptions. The system confirms the efficacy of monitoring the formaldehyde concentrations both indoors and outdoors, maintaining levels within the safe thresholds. The system demonstrates high accuracy, making it a viable solution for monitoring and regulating Formaldehyde emissions during biomass burning in the sugar industry.

Abstract

Benzo[a]pyrene is one of the compounds from the Polycyclic Aromatic Hydrocarbons (PAHs) group that is found in various places as a by-product of combustion. In addition, this compound also has carcinogenic properties so it has a bad impact on human health. Therefore, research is needed to detect the presence of benzo[a]pyrene compounds by designing a measurement system for this detection, especially in burning tobacco. The measurement system that has been designed uses a RobotDyn Mega WiFi 2560 microcontroller and an MQ-6 gas sensor that has been calibrated with benzo[a]pyrene compounds. The results showed that the concentration of benzo[a]pyrene detected when burning tobacco at a mass of 0.33 gram was 4.86 ppb, 7.38 ppb for 0.436 grams mass burning, and was 8.81 ppb for burning at a mass of 0.52 grams. Therefore, this measurement system has been able to detect benzo[a]pyrene compounds

Abstract

Energy Audit follows ISO 50002 standard had been done on one of gold mining industry in North Maluku, Indonesia that has operations involving two underground mining. As part of the energy audit report, this paper present energy sources and energy consumption, specific energy consumption cum energy intensity of the plant.  Energy audit methods include energy audit planning, opening meeting, data collection, measurement plant, siti visit, data analysis, energy audit reporting and closing audit. Most electricity data were collected from the SCADA system which the company use to monitor and control maximum electricity demand. Arithmetic mean, energy intensity equation and visual graphic methods had been employed to investigate energy profile and energy performance indicator of this gold mining. As the site located far away from the national grid then four Diesel powerhouses generates the electricity. Fuel consumption for four unit mainly electricity generation, transportation, heavy duty and supporting are investigated thoroughly. Since Diesel powerhouse occupy more than 80 % fuel consumption then the Diesel power houses is the Significant energy users (SEU). Further study SEC and on heat rate of the powerhouse is carried out and benchmarked with the IEA. It shows that the powerhouses have excellent performance as SEC and heat rate is lower than typical powerhouses. The powerhouse distributed electricity to four different unit, Kencana Underground Mining, Toguraci underground mining, Mill and Merril Crowe Processes and Supporting Unit. Among these units, Togurachi under gound mining with its uniqueness become the highest electricity end user as expected. It covers more than 40 % electricity consumption resulting quite high total energy intensity by ore milled which is approximately 475 kWh/ton (1710 MJ/ton) and energy intensity by Dore bullion is 1,420 kWh/ounce (5108 MJ/oz).
