Abstract

Fish is a type of food that is perishable. High production and perishable characteristics cause fish commodities to be immediately given storage or processing treatment so that they do not decrease in quality. The processing of fishery commodities has focused on producing foods with health effects for humans, such as functional foods, functional ingredients, and nutraceuticals. The health effects are caused by the content of bioactive compounds, one of which is bioactive peptides. Bioactive peptides are fragments from hydrolysis and have several biological functionalities such as antioxidant, anti-inflammatory, antihypertensive, anti-obesity, antimicrobial, and immunomodulatory properties. Generally, bioactive peptides can be produced from substrates such as foods with high protein content using enzymatic hydrolysis, chemical hydrolysis, and microbial fermentation technologies. However, these methods result in low peptide yields. Several emerging technologies have been applied in producing bioactive peptides, such as Ultrasound-Assisted Processing, Microwave-Assisted Processing, High Hydrostatic Pressure Processing, and Pulsed-Electric Field Processing. The application of emerging technologies is expected to produce peptides with high yield, fast, and low cost.

Abstract

Aluminum is an inorganic material that cannot be decomposed naturally in nature, while its presence in our lives is very abundant and quite crucial. One of its uses is as a raw material for food or drink cans. In the United States alone in 2012 around 38.2 billion cans of food or drink were produced. Therefore, efforts are needed to reduce aluminum waste. One use that can be made is by extracting the aluminum content in it to be used as raw material for alum coagulants and PAC. The aluminum that has been successfully extracted is then added with solutions that can cause polymerization and form alum and PAC coagulants. Next, the resulting synthetic coagulant was tested for its ability to reduce turbidity in laundry waste. Laundry waste itself was chosen because the waste processing is still simple, and generally, this type of waste contains suspended solids which can come from dirt attached to clothes or chemicals used in detergents. In this study, coagulation and flocculation were carried out with 500 mL of laundry waste sample taken and a synthetic coagulant dose of 100 PPM. After the coagulation-flocculation process was carried out, the sample was deposited with varying settling times of 30 minutes, 60 minutes, and 90 minutes. From the results of this research, it was found that synthetic PAC coagulant was more effective than alum in reducing turbidity in laundry waste. At the most effective deposition time, namely a deposition time variation of 30 minutes, the removal percentage was 57%.

Abstract

A bank can be considered good when it can satisfy its customers by providing excellent service and comfort. One of the banks facing challenges in this regard is PT. ABC Sidoarjo branch. This branch has only three teller services. In the queue, customers often feel uncomfortable, and bored, and their time is wasted waiting. This research aims to minimize waste to optimize the teller service queue. The research starts with data collection, distributing questionnaires, and analyzing data using Lean Service methodology. To visualize the value stream of business processes at PT. ABC, Value Stream Mapping (VSM) is used. Cash deposit activities contribute significantly to waste. Within the cash deposit service process, it was found that value-added activities account for 64%, necessary non-value-added activities for 29%, and non-value-added activities for 7%. The critical types of waste are waiting and unnecessary movement, each with a percentage of 24% and 22%, respectively. After the research and proposed improvements were implemented, After the improvement, the non-value-added activity decreased from the initial 900 seconds to 300 seconds, which represents a 66.7% reduction. As a result, customers no longer need to wait in line for an extended period.

Abstract

Maternal parenting stress can occur because mothers are the main caregivers who will face daily problems, especially those who have children with disruptive behavior. The purpose of this study was to determine the relationship between a hardiness personality and a husband's social support with a mother's parenting stress in dealing with children's disruptive behavior simultaneously or partially. Using a quantitative approach with the number of participants as many as 61 mothers who have preschool-age children (3-5 years old), have gone to PAUD (KB or TK) in Semarang City, and the child has disruptive behavior. Participants were selected through the accidental sampling method and data analysis using multiple regression analysis. The results showed that there was a very significant simultaneous relationship between hardiness personality and husband's social support with mothers' parenting stress in dealing with children's disruptive behavior, with an effect of 32.0%. There is a negative and very significant relationship between hardiness personality and parenting stress of mothers in dealing with children's disruptive behavior with an effect of 19.4%. When dealing with children's destructive behavior, there was a positive and significant relationship between the husband's social support and the mother's parenting stress, with an effect of 12.6%. This study aims to demonstrate that maternal resilience is an important factor in reducing or suppressing maternal parenting stress when dealing with children's disruptive behavior. A limitation of this study is that the scale is extended using Google Forms, so researchers cannot see participants' reactions when they provide information to complete the scale in Google Forms. A suggestion for future researchers is to conduct a broader study on mothers' parenting stress in different cases, such as children's use of gadgets and devices.

Abstract

The effectiveness of the system of public education in a country is one of the most important aspects of its development. The COVID-19 initiative affected the educational system previously. The education system in Indonesia, however, is utilizing the offline or non-network learning approach now that the COVID-19 pandemic conditions, particularly in Indonesia, have abated. The teaching and learning process that takes place in schools exposes pupils to issues that develop in the educational setting and are frequently experienced by students. The frequent occurrence of saturation and exhaustion during school activities is one example. The objective of this final project is to determine the level of saturation and fatigue in offline learning among students at ABC Elementary School and to propose improvements to minimize the levels of saturation and fatigue. The methods used for research are MBI-SS (Maslach Burnout Inventory-Student Survey) for the level of saturation and SOFI (Swedish Occupational Fatigue Inventory) for the level of fatigue. The research results from 75 students show that for the level of saturation, there are 49 students (65%) in the low category, 25 students (34%) in the moderate category, and 1 student (1%) in the high category. For the level of fatigue, there are 56 students (75%) in the moderate category, 19 students (25%) in the moderate category, and 0% in the high category. To saturation and fatigue, the school can engage in ice-breaking activities, inject humor during learning sessions, and provide additional nutrition such as pudding or similar items in the morning.

Abstract

XYZ is a company operating in the manufacturing and rubber roll service industry located in Indonesia. The frequent issue within the company is the occurrence of product rejects, leading to inefficient production processes. The research is conducted using the Fault Tree Analysis (FTA) method with recommendations for improvement from the Failure Mode and Effect Analysis. This method is employed to identify the causes of product rejection and provide preventive solutions to avoid such rejections. There are three types of rejects at PT. XYZ, namely blisters rejection with a probability of 1.137%, material impurities rejection with a probability of 1.18%, and PU rejection with a probability of 1.152%. The root causes of these rejections include operators rushing, operator fatigue, machines in need of maintenance, very short production deadlines, operator laziness, incomplete environmental cleanliness facilities, and operators joking around while working. As for recommendations to reduce and prevent the recurrence of these three types of rejections, they include regular machine maintenance, providing customers with longer estimated completion times than the actual estimates, and offering rewards to operators who meet targets without making errors.
