Abstract

Tempeh is a typical Indonesian food that is consumed by almost all people. In the industrial world, companies are required to increase productivity because many competitors are increasingly competitive. The increase in raw material prices makes companies reluctant to buy materials in large quantities, so companies tend to maintain stock or supply of materials in order to meet increasing demand. This research aims to estimate the amount of tempe production using the Mamdani fuzzy logic approach with consideration factors in the form of supply and consumer demand. The research method uses literature reviews, testing with Matlab, and manual calculations to analyze demand and supply of tempeh in the industry. The test results using Matlab and manual calculations on tempe demand and supply obtained data that is in accordance with existing history, where if there is a demand for 6006 units of tempeh with a raw material supply of 6945, then it is predicted that the company will produce 6569 units of tempeh. It is hoped that this research can help the tempe industry in preparing production plans.

Abstract

Mango (Mangifera indica) quality assessment poses challenges in traditional grading methods, primarily relying on visual inspection, which can be subjective. This research aims to develop a Fuzzy Inference System (FIS) for evaluating mango quality based on parameters such as color, size, and spots. A qualitative data collection approach was employed through literature review and expert opinions, followed by the application of fuzzy logic using MATLAB to analyze the parameters affecting quality. The results demonstrate that mangoes classified as "Good" are characterized by larger size, a high or medium distribution of red color, and small spots. Defuzzification was performed using the Centroid Method to derive a crisp output, which indicated a quality leaning towards the "Well" category with a value of approximately 0.5584. This study highlights the efficacy of fuzzy logic in transforming qualitative assessments into quantitative measures, enhancing the reliability of agricultural evaluations.

Abstract

This study investigates the application of fuzzy logic to optimize yeast concentration and fermentation time in tempeh production. Tempeh, a traditional Indonesian food made by fermenting soybeans, requires precise conditions to ensure high quality, including optimal yeast concentration and incubation duration. Fuzzy logic provides a flexible approach by allowing variable inputs within ranges, rather than fixed values, making it ideal for controlling uncertain factors in fermentation. The study used MATLAB software for fuzzy logic modeling, incorporating yeast concentration and fermentation time as input variables and tempeh quality as the output. Key parameters for each input were defined, and fuzzy rules were applied to predict tempeh quality under varying conditions. Results indicate that a yeast concentration of 30% and a fermentation time of 53 hours yield a quality rating of 6.9, indicating satisfactory tempeh. The fuzzy model proved accurate, with close alignment between predicted and actual results, underscoring fuzzy logic's effectiveness in refining fermentation processes.

Abstract

This research aims to develop a fuzzy logic control system for optimizing temperature and humidity during cocoa bean fermentation. The study employs a literature review method and data analysis using MATLAB. A Mamdani-type fuzzy inference system is designed to control the temperature and humidity of a cocoa bean dryer. Input variables include temperature (0-65°C) and humidity (0-100%), while output variables are heater and fan settings. The system's performance is evaluated using a case study, demonstrating its ability to adjust heater and fan operations based on environmental conditions. Results show that for an input of 65°C temperature and 50% humidity, the system recommends turning off the heater (membership value 79.8) and running the fan at high speed (membership value 84.7). This fuzzy logic approach offers a promising solution for maintaining optimal conditions during cocoa bean fermentation, potentially improving the quality and consistency of the final product. Keywords: cocoa fermentation, fuzzy logic control, temperature regulation

Abstract

This research focuses on determining the amount of tofu production based on the amount of consumer demand and the amount of raw material inventory. Optimization of daily tofu production is a difficult problem due to uncertainty of supply an demand for tofu. The method used in this research is the fuzzy logic method which is one of the effective rule-based approach methods to determine the volume of tofu production. In this research, the data used is taked based on the results of previous research. The final results obtained in this study, namely the determination of the volume of tofu production based on the amount of consumer demand and the amount of raw material inventory is still less effective. This is because the amount of consumer demand received and the amount of raw material inventory available with the volume of tofu production produced is still not appropriate

Abstract

The abundance of packaged milk products in the market requires consumers to consider several factors to obtain high-quality packaged milk at an affordable price. Milk demand in Indonesia showed a slight increase from 2019 to 2020, rising from 16.23 in 2019 to 16.27 in 2020. However, the average milk demand in Indonesia has remained fluctuating, largely due to the increasing prices of milk products on the market. This study aims to determine the recommendation level for packaged milk by considering both price and nutritional content. The method used in this research involves a mathematical assessment of milk products using fuzzy logic. The data for this study is derived from previous research on packaged milk samples as the observation objects. The results indicate that sample 16 is highly recommended due to its low price and very high nutritional content.

Abstract

Fuzzy logic is widely used in various fields to formalize human behavior by considering inaccurate or partial reasoning. This study implements the Tsukamoto fuzzy logic method to analyze tempe production based on demand and inventory data. The research utilizes library research methods and data analysis using MATLAB (Matrix Laboratory). The Tsukamoto method was chosen for its high tolerance for data and flexibility. The system uses two input variables: demand and inventory, with output being production quantity. The fuzzy sets for demand are categorized as "Decrease" and "Increase" with a domain of [1000; 2000], inventory as "Few" and "Many" with a domain of [100; 600], and production as "Decrease" and "Increase" with a domain of [1520; 2100]. Using four fuzzy rules and the defuzzification process, the system can predict optimal production quantities. For example, with a demand of 1500 and inventory of 400, the system calculates a production quantity of 1823 units. This implementation demonstrates the effectiveness of the Tsukamoto method in automating production decisions based on demand and inventory variables.

Abstract

Milk is a highly nutritious food obtained from milking animals. One way to process milk so that it lasts a long time is by pasteurization. This study aims to develop a pasteurized milk damage level assessment system based on fuzzy logic based by considering factors such as temperature, storage time, pH, and the number of social cells. The method used in this study is a qualitative descriptive method with a literature study approach to collect secondary data from various relevant sources. The milk damage assessment system is designed using Fuzzy Inference System Mamdani, where each input variable is regulated by a trainee membership function. The results show that the system can provide a more accurate and adaptive assessment in determining the risk of milk damage, specified through the fuzzy rule evaluation designed for each combination of input conditions. This system is expected to support better decision making in maintaining the quality of pasteurization.

Abstract

Catfish (Clarias sp.) larvae are highly sensitive to environmental changes, particularly in water quality parameters such as temperature, pH, and dissolved oxygen (DO), which significantly affect their survival rate (SR). This study aims to design a real-time prediction system for catfish larval survival using Mamdani fuzzy logic to support more accurate and adaptive water quality management. The research was conducted from April to May 2025 at the Hatchery, IPB Vocational School. The methodology involves constructing a Mamdani fuzzy inference system in MATLAB based on secondary data (SNI 6484:3:2014 and previous studies) and field observations. Three main input parameters temperature, pH, and DO. Were categorized into fuzzy sets using triangular membership functions. A total of 84 fuzzy rules were developed to infer SR, which was also divided into three categories: low, moderate, and high. Simulation results using the Rule Viewer and Surface Viewer showed that DO had the strongest influence on SR followed by temperature, while pH had a relatively minor effect. Under low DO conditions (<3 mg/L), SR predictions were consistently low regardless of other variables. In conclusion, the Mamdani fuzzy logic system proves effective in predicting catfish larval SR and can be a valuable tool for optimizing aquaculture practices.
