Abstract

The main problem with the availability of ground water is generally due to the relatively deep wells of residents (information from residents of more than 50 m), so that it requires very expensive production well excavation costs, especially for villagers. Many people in Tegalweru Village, Dau District, Malang Regency still have not utilized the potential of groundwater in the area. The use of clean water is still sourced from other than ground water. This is because there is no information related to the presence of groundwater. The purpose of the study was to determine the soil layer that has groundwater potential (aquifer) based on the distribution of resistivity values and can be used as a basis for consideration in making boreholes. Based on geoelectrical data processing and analysis, it can be concluded that the groundwater potential in the garden area has good groundwater potential by identifying several aquifer layers up to a depth of 145 meters. The geoelectric point rock lithology no. 01, 02 and 03 consists of top soil, tuff and breccia layers.

Abstract

Graduates as the end product of educational institutions are the quality objective and benchmark for the success of educational institutions. One strategy for obtaining feedback from graduates is using Tracer Study. This study aims to find and then analyze associative patterns can be found in the IBI-Kosgoro 1957 tracer study data. The search for association rules is carried out using the apriori algorithm. These patterns will be used to evaluate the characteristics of IBI-Kosgoro 1957 graduate students. Implementation of data mining is done using the Python programming language and executed using Google Colabs. The dominant characteristics of the IBI Kosgoro 1957 graduates are there are more non-entrepreneurial office workers, less active in organizations, moderate GPA scores, but can speak at least one foreign language and the most language is English. There are more who work not according to their educational background than work according to their scientific field, the proportion is almost the same. The GPA value itself does not affect success in getting a job that earns above UMP. Even so, 30% of them earn above UMP. With a minimum support of 10% and confidence above 50%, graduates will work according to their field of knowledge and earn an income above the UMP if they are bilingual, not actively organized and quickly looking for work.

Abstract

Overhaul activities, especially plate disassembly and installation (replacement expansion joint No.6) involve a lot of labor, have a high working intensity, and use diverse work equipment. In this work process, it is carried out manually handled by a total of 9-13 daily workers and there is a process of lifting expansion joint plates with a length and width of at least 5 meters with a plate weight of 1500 kg so that with a heavy and diverse workload it is necessary to ensure occupational safety and health (K3) of the workers. This work has the possibility of a risk of work accidents from mild to severe scale if a good K3 Management System (SMK3) is not carried out. SMK3 has a role in reducing the level of risk using appropriate risk control as well as being implemented so that workers can work safely and comfortably. Hazard Identification Risk Assessment and Determining Control (HIRADC) is one of the methods in the risk management system regulated in OHSAS 18001:2007 in clause 4.3.1 and hazard control based on a hierarchy of risk control measures is based on ISO 45001:2018. The results of this study were from 11 activities with 32 job descriptions after identification of hazards in terms of the work environment, labor, and tools used as well as risk assessment there was an initial risk level to an extreme scale. Thus, it is necessary to handle and recommend in the form of qualitatively descriptive hazard/risk control from K3 management in the workplace to create a safe and comfortable work environment and can reduce the level of risk that exists.

Abstract

The media used by educators in the teaching and learning process is an important factor that influences the level of understanding of students. Innovations in learning media in the current era of technological development, can provide opportunities for educators to always strive to provide learning media that are easily accessible, understood in depth, and can function effectively. The use of appropriate learning strategies becomes a method that can be used by educators in the process of strengthening cognitive, affective, and also motoric aspects. An initial study conducted by researchers on 50 Industrial Engineering students at the Yogyakarta Technological University, showed that 32% of students had difficulty understanding the material in the Ergonomics course related to Anthropometry (measurement of human dimensions) due to the limitations of the media in the learning process of the material. This study aims to produce a design of learning media that can provide convenience for students in understanding Anthropometry material. This research and development method uses the Lee & Owens model by carrying out 4 stages, namely Assessment/analysis, Design, Development and implementation, and Evaluation stage. The result of this research is an Augmented Reality-based application called AR Anthropometry. This application provides 3-dimensional visualization using augmented reality technology equipped with materials and quizzes as a benchmark for achieving student convenience in understanding anthropometric material.

Abstract

The agricultural sector is a promising sector in the future, but in Indonesia the agricultural sector has not developed properly due to many factors such as individual land ownership which tends to be narrow, young people who do not want to continue their parents' business in farming, then 60% of farmers in Indonesia still relies on traditional farming systems, regardless of water needs, seasons, climate, sales prices, types of plants and others. Traditional farming systems also require high costs, so the income is less than optimal. According to BPS, in the second quarter of 2022 the highest economic sector was found in the business fields of agriculture, forestry and fisheries at 13.15%. This potential should be developed in the industrial era 4.0, as an example of technology that can be applied in the agricultural sector, namely the Internet of Think, a system is needed to control water demand, temperature and light intensity needed to help plant photosynthesis. The proposed system will use four sensors including a light sensor (LDR), a temperature sensor (dht-11), an ultrasonic sensor, and a soil moisture sensor. In this proposed system monitoring can also be carried out using the Blynk application which can be monitored via a smartphone. The system development process uses the Rnd method, because the Rnd method is suitable for making products that can be applied to support agriculture.

Abstract

Humback Grouper (Cromileptes altiveles) is a type of grouper fish that has high economic value. Currently the problem faced in grouper farming is the low survival rate due to cannibalism. This study aims to determine the effect of stocking density on the growth and survival of  Humback    Grouper (Cromileptes altiveles) seeds from stages D60–D120. This study used a completely randomized design with four treatments at densities of 2 individuals/10 liters, 4 individuals/10 liters, 6 individuals/10 liters, and 8 fish/10 liters repeated for each treatment three times. The feed was given in the form of chopped trash fish with a frequency of twice a day in the morning and evening. Growth data (absolute growth data, daily growth data) and survival data were analyzed using analysis of variance (ANOVA) to show that the treatment had an effect on growth and Humback  Grouper (Cromileptes altiveles) survival rate and Duncan's  test to find out the difference in mean values between treatments. The results showed that stocking density had a very significant effect on absolute growth and daily growth rate, and had a significant effect on survival. Treatment A (2 fish/10 liters) produced the best absolute growth, daily growth rate, and survival with values of 20.047 g, 3.303%/day, 100%, respectively.
