Abstract

Culture is people's reflection, hard work, and wisdom to navigate their world, namely a culture that allows people to see their environment in a meaningful way. Indonesia has diverse cultures, one of which is traditional Chinese culture. Over time, the Chinese culture in Indonesia has gradually faded to this day. This study aims to develop a 2D animated video to introduce Chinese tradition and culture as the identity of Chinese people in Indonesia, especially Gen Z children. Using a research and development approach and testing the EPIC model's effectiveness. The research conducted included interviews with several Mandarin teachers and students studying in China. The development phase uses the MDLC (Multimedia Development Life Cycle) model and continues with quantitative research using the EPIC model. These search results are 2D animated videos posted on YouTube that last 3 minutes and 35 seconds. The EPIC model's quantitative demonstrate how 2D animated videos effectively introduce culture to younger members of Generation Z. Empathy, persuasion, influence, and communication values all show this. The mean of the EPIC ratio is 4.16. The persuasion and communication dimension got the highest score compared to other dimensions at 4.26.

Abstract

The Trans Semarang application is built by “UPTD”, the Public Service Agency of Trans Semarang to provide information about bus routes, ticket price, the nearest bus, and tourism. Referring to Playstore, there are a lot of complaints from users especially in difficulting usage of the application. This becomes a reason to evaluate the usability to find problems on user interface which is conducted through heuristic evaluation method by using the ten principles usability indicator. The result of this research is there are several problems, with the average of low problem by the low priority recovery and 2 aspects of problems with high priority recovery recommendation namely Consistency and Standard aspects with savering rating about 3,4. In addition, the results of this study are expected to be used as a reference and recommendation for developing the Trans Semarang application to make it easier and more comfortable for users.

Abstract

This experimental research attempts to examine PLTMH on water reservoirs with 1/2" pipes with height variations of 1 meter, 2 meters and 3 meters and the use of several generators installed in series. The test aims to determine the height and number of generators that produce more optimal power.In conducting data analysis, the researchers also employed the descriptive method from Miles and Huberman. The results of the first experimental test were to determine the value of flowrate of 4,166 m3/s and the water pressure about 0.01 MPa at a height of 1 meter, 0.02 MPa at an altitude of 2 meters and 0.03 MPa at a height of 3 meters. The results of the flowrate and water pressure tests were used as a benchmark in testing the PLTMH with 5 types of DC generator test circuits with a load, namely the 12V 3W LED lamp. The result shows, the power is 2.675W and the voltage is 53.50V with a current of 0.050A. It is affected by the water level, the water pressure will increase, consequently, the hydrostatically water pressure hits the turbine blades which affects the rotation of the generator which produces high power.

Abstract

On Karawang utara has problems with groundwater and coconut waste. Groundwater in the area is crusty and yellowish in color. Coconut waste comes from sellers who only take coconut meat and water, leaving coconut husks and shells. To overcome these problems, conducted groundwater quality test and made water filters from coconut waste. The parameters tested were pH, TDS, manganese, and iron. According to Minister of Health Regulation Number 32 of 2017 and Regulation of Minister of Health Number 492 of 2010, groundwater quality testing showed that groundwater in all areas of Karawang utara can be used for sanitation purposes, but only Pedes and Tirta Jaya regions can be used as raw material for drinking water The design of the water filter from coconut waste is designed to solve this problem.. The results of groundwater testing after the filtration process have values below the threshold of PerMenKes Number 492 of 2010 which indicates that groundwater after the filtration process can be used as raw material for drinking water. The effectiveness of water filters from coconut waste reduces TDS 32.05%, manganese 82.01%, and iron 83.33%. The design of a water filter that has been made is proven to be able to solve groundwater problems and coconut waste problems in Karawang utara.

Abstract

Calcium carbonate (CaCO3) is known as an inexpensive inorganic mineral commercially. Currently, calcium carbonate is widely used as a carrier for animal probiotics. As a carrier material, the use of calcium carbonate must be free from bacterial contamination. This is so that the probiotics production also do not contain bacteria other than the probiotics themselves. The method used was descriptive quantitative method. This study focused on examining the effectiveness of the calcium carbonate sterilization process with the dry sterilization process using an oven and the wet sterilization process using an autoclave based on the total plate count of bacteria. Based on the research, the normal treatment or without sterilization, Total Plate Count (TPC) calcium carbonate results were < 2.2 x 103 cfu/mL, in the wet sterilization treatment using an autoclave the total plate count was < 1.1 x 103 cfu/mL and the results in the sterilization treatment dry using an oven the total plate count was 0 colonies. The dry sterilization method using an oven is more suitable for calcium carbonate sterilization than the wet sterilization method using an autoclave. In the water content test, the same results were obtained for the three calcium carbonate treatments. This indicates that the dry and wet sterilization methods for calcium carbonate did not affect the percentage of water content contained therein. In the pathogen test, negative results were obtained for Escherichia coli and Salmonella sp in all three treatments.

Abstract

Google Scholar is an online platform that provides access to scholarly literature such as articles, theses, books and conference proceedings from various scientific publishers. As educators or lecturers, they should have scientific research works that can be accessed by anyone at any time. To measure achievement and access to publication of scientific papers quickly and to profiling educators, lecturers or researchers, universities must have a centralized database that comes from a Google Scholar account and can be updated periodically or automatically based on a specified period. To solve this problem, the researcher implements a web scraping technique combined with a cron job as a command that will run a task on a scheduled basis. The method used is the RAD (Rapid Application Development) method which focuses on a fast system development process. This study succeeded in scraping data for 2983 documents, displaying document citation data globally and successfully carrying out an automatic scheduling synchronization process that is set with scheduling configurations every week, every month, every quarter, every semester and every year, and scripts on cron jobs are run every 5 minutes on the server to check if any scheduling is active.
