Abstract

Along with advances in technology, the use of human labor in managing agricultural products is decreasing because it has been replaced by robots. Robots perform better than human workers who have emotions and need time to rest. This can cause errors when sorting fruit due to lack of concentration caused by fatigue. The large harvest of oranges takes a long time to sort them, starting from color, size, weight, and price, before they are marketed. To make it easier for farmers to sort their harvest from orange fruit, this research was created titled "Citrus Fruit Sorting System Based on Size and Color Based on Fuzzy Logic." The sorting system based on color and size that will be made has the advantage that the fruit being sorted is more varied because it is equipped with fuzzy logic. Fuzzy logic allows membership values between 0 and 1, levels of gray as well as black and white, and in linguistic form, uncertain concepts such as "a little," "fairly," and "very." Apart from that, the system is made more human-friendly because the rule base is created by humans. The sorting tool that was made to be controlled using an Arduino UNO board with the help of Arduino IDE software managed to obtain a success rate of 62.5% for the low and medium-quality classes and a success rate of 87.5% for the high-quality class with an overall average success rate of 70.8 %.

Abstract

The recurring problem among Genshin Impact players in choosing characters, especially for new players, is a common issue. Therefore, this study aims to develop a decision support system to assist players in selecting characters using the weighted product method. The study was conducted by collecting data on the available characters in Genshin Impact and evaluating relevant criteria such as character rarity, role, weapon, and element. There are 52 characters or alternatives used in this study. The weighted product method was used to determine the relative weights of each criterion and then used to calculate the value of each character. In conclusion, the implementation of the weighted product method has been successfully carried out based on the three main steps, which are determining the weight of criteria, normalizing alternatives, and determining the preference of each alternative. From the results of the system testing that has been conducted by 25 users, a percentage of 84% was obtained based on user satisfaction with the decision support system for character selection in the Genshin Impact game. 9 respondents chose the option "strongly agree" and the remaining 16 chose the option "agree", indicating that the system is satisfactory for what the users want.

Abstract

Chili is a vegetable commodity that has high economic value so that its production always increases every year. Several types of chilies are cultivated in Indonesia, namely cayenne pepper (Capsicum frutescens), curly red chili (Capsicum annuum L. var. longum), large red chili (Capsicum annuum L.) and paprika (Capsicum annuum var. grossum). Indonesia is a country that continues to develop innovation to produce many superior varieties, especially chilli plants. The problem arises that variations of other superior chili varieties can only be accessed through the official website of the ministry of agriculture, however, the data that can be accessed is limited (in the form of descriptions of chili varieties without physical appearance such as photos) so that it is quite difficult for the community and farmers to cultivate or utilize these varieties. This made researchers develop a digital encyclopedia of chili types using computer vision. This study uses a combination of digital image processing and intelligent systems. The image processing used is preprocessing such as cropping and splitting of RGB components, image segmentation and shape feature extraction. The features used are area, perimeter, major axis length, minor axis length and eccentricity. This feature is the input of the Naïve Bayes method which produces a system accuracy rate of 92%.

Abstract

There are more than 70 small tofu factories in the Jogoroto District, which generate a large amount of liquid waste from tofu processing that has not been treated optimally. This certainly creates a potential for the waste to contaminate groundwater in the Jogoroto District. The assessment of groundwater vulnerability to contamination can be conducted using the DRASTIC method, which involves 7 parameters.In this study, there are 24 dug well points spread across the entire Jogoroto District, which were monitored periodically over a 5-month period, from July 2023 to November 2023. Based on the resulting groundwater vulnerability distribution map, laboratory tests on groundwater quality were carried out, using parameters from the Minister of Health Regulation No. 2 of 2023 concerning clean water and the Minister of Environment Regulation No. 5 of 2014 on effluent quality standards.The study found that the DRASTIC index value during the research period ranged from 140 to 212, with three levels of vulnerability: moderate, high, and very high. The high vulnerability level dominated the study area. However, based on the validation results, it was found that the groundwater quality in the Jogoroto District, Jombang Regency, is not contaminated.

Abstract

This simulation aims to determine the effect of the percentage of potential resistance on the waves produced from a dc motor circuit using IC 555 as a wave generator. The simulation results show that the smaller the percentage of potential resistance, the faster the RPM on the motor with the greater the voltage and amperage on the motor. The resulting wave has a very strong influence on the potential resistance, the smaller the resistance, the longer the wave produced by the IC 555 will be and will have a relatively short density. Analysis shows that changes in resistance percentage affect the voltage, amperes, RPM and waves on the motor

Abstract

Automatic lights with light sensors are lights that can turn on and off automatically without using a switch. The light sensor in automatic lights works by converting light quantities into electrical quantities. The working principle is that when the sensor detects the presence of light, the light will turn off, and vice versa. Here are some of the benefits of using automatic lights with light sensors: Save energy and reduce electricity bills, Increase comfort, Reduce the need to adjust lighting manually, Save labor and time. Light sensors work by utilizing the principles of electric current and resistance. When light hits the sensor, the resistance will increase or decrease according to its position, thereby regulating the current

Abstract

Activities in the Beji River area such as bathing, washing, toilets, industry, and agriculture greatly affect the declinein the quality of the river's. Poor river surface water quality will affect the quality of groundwater in the area around the river.Groundwater and river surface water have a close relationship with each other, especially in areas around riverbanks. Therefore,this study was conducted to identify the interaction between ground air and river surface air at the research location. Based onthe description of the flow pattern identified as a whole, the type of interaction at the research location is in the form of gainstream. The relationship between the two causes similar characteristics as evidenced by the occurrence of similar patterns in thetime series analysis. These similarity characteristics are divided into 2 clusters, namely cluster 1 is influenced by pH and airtemperature while cluster 2 is influenced by TDS and DHL water with correlation values ranging from -0.074 to 0.972. Based onthe PCA analysis, the eigenvalue values obtained range from 1.042 to 1.482 with a cumulative contribution of variables of 79.58%.The hydrochemistry of air in groundwater and river surface water also shows that there are similarities in the chemical propertiesof air, namely that it has non-dominant types of cations and anions.

Abstract

This research utilizes Gas Metal Arc Welding (GMAW), a process whose performance characteristics significantly influence weld strength, particularly tensile capacity and flexibility. Higher electrical control contributes to increased tensile strength in welds, sometimes exceeding the base metal's tensile strength. However, during bend testing, lower electrical settings typically result in defects or cracks. Critical GMAW parameters power, voltage, and welding speed require precise adjustment to enhance weld quality. This study evaluates the impact strength of GMAW-welded steel using Charpy testing with 70° V-joints at currents of 90, 110, and 130 Amperes. The highest impact strength occurred at 110 Amperes, indicating optimal toughness, while 90 Amperes yielded low toughness. Fracture analysis revealed ductile fractures in 90-Amp specimens and mixed-mode fractures at 110/130 Amperes.

Abstract

The use of composite materials in the automotive industry has become a critical topic over the past decade, driven by increasing demands for lightweight, fuel-efficient, and environmentally friendly vehicles. This review examines the development and application of composite materials—particularly Carbon Fiber Reinforced Polymer (CFRP) and Glass Fiber Reinforced Polymer (GFRP)—in automotive structural components. The study employs a systematic literature review of 15 scholarly sources from databases such as Scopus, Google Scholar, and ScienceDirect, with inclusion criteria focusing on peer-reviewed publications (2014–2024) relevant to mechanical engineering and automotive applications. The findings indicate that CFRP and GFRP can reduce vehicle weight by 30–40%, significantly improving fuel efficiency and reducing carbon emissions. However, challenges such as high production costs, complex manufacturing processes, and recycling limitations hinder widespread adoption. Recent trends highlight growing interest in bio-based and hybrid composites, alongside advancements in manufacturing technologies like resin transfer molding (RTM) and automated fiber placement (AFP) as potential solutions. In conclusion, composite materials hold immense potential for automotive innovation, but further research is needed to integrate material science, manufacturing scalability, cost-effectiveness, and environmental sustainability to ensure long-term viability
