Abstract

MSMEs Heler Sari is one of the rice millers in Payakumbuh, West Sumatera. In running a rice milling business, the owner has never measured the standard time of workers, so the management cannot determine the optimal number of workers. This research aims to measure the standard time of workers in MSMEs as a consideration for owners in optimising productivity by paying attention to allowances and worker factor ratings. This research is quantitative with a time study approach using a stopwatch as the primary data source. The research results showed that the standard time for each work element for lifting grain was 6.023 minutes, drying grain 10.2 minutes, putting grain into sacks 7.264 minutes, putting grain into the mill 11.373 minutes, sewing rice sacks 1.928 minutes, putting rice into sacks 3.489 minutes, lifting rice to storage 3.89 minutes. 3.89 minutes. Measuring work is very important, especially knowing the standard times of work components. Increasing productivity can reduce time and costs and achieve production goals.

Abstract

The Katingan Hilir District of Katingan Regency, Central Kalimantan Province, is one of the areas experiencing the consequences of flood disasters. This research aims to analyse the flood-affected areas using the GIS method, integrating the Analytic Hierarchy Process (AHP) method in order to analyse the impact and influencing factors on flood events. This is one of the decision support system methods of Multiple Attribute Decision Making (MADM), which is included in the technical category. MCDM (Multi-criteria decision making) was developed by Thomas L. Saaty with the objective of identifying the most optimal and feasible problem-solving/alternative results through systematic evaluation procedures [1]. The parameters obtained based on the ranking of their influence on flood vulnerability are as follows: The following parameters were identified as influencing flood vulnerability: rainfall, distance from the river, slope, elevation, soil type and land cover. The results of the map overlay indicated that a total area of 403.11 km2 (67.1%) exhibited a low level of flood vulnerability, 146.93 km2 (24.5%) exhibited a medium level of flood vulnerability, and 50.34 km2 (8.4%) exhibited a high level of flood vulnerability. The area and percentage values indicate that the study location is a dominant area with a low level of flood vulnerability, yet it has a high category of flood-prone percentage approaching 10% of the total administrative area of the sub-district.

Abstract

The aim of this study was to create and evaluate the quality of organic fertilizer using Unripened coconut waste. The process involves chopping the waste into small pieces and placing it in a container or bucket. EM4 activator liquid is then sprayed onto the waste, followed by the addition of molasses. This process is repeated for the second and subsequent batches. The prepared Unripened coconut waste is covered withblack plastic to maintain anaerobic conditions and a temperature of no more than 60°C. The pile is turned multiple times to stabilize the temperature at ± 35-45°C. The first turning occurs after one week, followedby weekly turning for up to one month. The resulting fertilizer is dried through aeration, sieved, and tested for quality. The water content was determined using the distillation method, while total nitrogen wasmeasured using the Kjeldahl method. Phosphorus was quantified using a UV-Vis Spectrophotometer, and potassium was analysed using AAS. The results indicate that Unripened coconut waste can be utilised as an organic fertiliser. The fertiliser is brown in colour, soft in texture, has an earthy smell, and a temperature of 28°C. The organic fertiliser contains 22.8% water, 0.833% nitrogen, 0.118% phosphorus, and 5.616% potassium. The produced organic fertilizer meets the specifications for fertilizer from organic waste based on nitrogen, phosphorus, and potassium content according to SNI 19-7030-2004.

Abstract

Florpyrauxifen-benzyl, a synthetic auxin herbicide, has recently been introduced for weed control in rice cultivation in Indonesia. However, limited research has been conducted to investigate its environmental impacts, particularly in the Indonesian context. This review article aims to provide a comprehensive overview of the current understanding of florpyrauxifen-benzyl, based on scientific articles published by global scientists over the past six years. The article systematically reviews and categorises the development of studies on florpyrauxifen-benzyl into three main clusters: weed control efficacy, residue fate and environmental impact. The weed control cluster examines the efficacy, selectivity and potential resistance issues associated with the herbicide. The residue fate cluster focuses on method development, residue measurements in different matrices and degradation pathways. The environmental impact cluster will address the holistic ecological impact of florpyrauxifen-benzyl, including effects on environmental quality (water, sediment, soil), micro-organisms, non-target agricultural crops, fauna and humans. This compilation of current knowledge on florpyrauxifen-benzyl will serve to inform environmental mitigation strategies and identify knowledge gaps that require further investigation in the future to support sustainable agricultural practices in Indonesia.

Abstract

The production process is important to the success of a business, and inventory is a key factor in maintaining smooth production. Problems often arise with the inventory of raw materials in the production process,especially when long storage can affect their quality, or when ordering is too frequent, resulting in high inventory costs. Mom's Yogurt, a manufacturer of preservative-free products, uses milk and sugar as its main ingredients. The purpose of this study is to find the optimal amount of raw materials to order, the optimal frequency of ordering, and to reduce inventory costs by using EOQ and JIT methods. Based on the research results, the optimal order quantities of milk and sugar according to EOQ are 548 litres and 100 litres, with order frequency of 6 and 3 times per year, respectively. The total inventory costs are Rp 139,643.08 and Rp 81,649.73, respectively. Using the JIT method, the optimal order quantities of milk and sugar are 3,750 litres and 235 litres, with an order frequency of 1 and 2 times per year, respectively, with total inventory costs of Rp 20,396.60 and Rp 33,994.40. Looking at the results of the calculation of total inventory cost, the results of the calculations with EOQ and JIT resulted in a significant reduction in the cost of milk and sugar inventory compared to the company's policy method. EOQ decreased by 89.29% and 83.78% respectively, while JIT decreased by 98.44% and 93.25% respectively.

Abstract

Fire protection can increase occupational safety and security factors from fire hazards. Therefore, this research aims to design a fire protection system in an integrated laboratory building. The fire protection design is active fire protection, namely yard hydrants and fire extinguishers. This research uses engineering research methods. The standards used are NFPA 14, NFPA 24, Regulation of PER.04/MEN/1980 and SNI 03-1375-2000. Fire extinguishers are designed by determining the minimum number of extinguishers required and the type of extinguishers to be used. The yard hydrant design is carried out by determining the minimum number of yard hydrants required. Based on the research results, 22 fire extinguishers are required on the 1st floor, while 12 fire extinguishers are required on each of the 2nd and 3rd floors. Based on the fire class, the recommended APAR is dry chemical powder and CO2. The number of hydrants required is 9, the groundwater tank volume is 130 m3 and the obtained flow is 0.04 m3/s with a total head of 54,342 m. The appropriate pump specification is therefore the Ebara centrifugal pump type 150x125 FS4LA with a power of 54,342 kW.

Abstract

The control and monitoring of the water tank, located on the third floor of the building, continues to face problems related to the filling process and limited monitoring. Water continues to enter the tank unnoticed, resulting in energy wastage. This study aims to create a framework that can monitor the water level in the tank of a three-storey building using Internet of Things (IoT) technology. The tank's water level monitoring system uses a JSN-SR04T ultrasonic sensor to collect water level data, with a Node MCU serving as the microcontroller. The system can monitor water levels from 0% to 100%. A reading of 0% indicates that the water is at its minimum level, while 100% indicates that the water tank has reached its maximum capacity. The system created can monitor excessive water consumption at each level using a flow meter sensor. The Virtuino application can stop the water flow by pressing the ON button, which activates the relay in the design model and stops the water flow at any desired level. The water pump will start to fill the reservoir until it reaches the desired level set by the user based on their needs.
