Abstract

Chili peppers are fruits or plants of the genus Capsicum. Fruits can be classified as spices or vegetables. As a spice, chili peppers are very popular in Southeast Asia as a food flavor enhancer. Chilies have some nutritional content in 100 grams of it, which content: Water, energy, protein, fat, carbohydrates, fiber, calcium, etc. Chili also has several benefits, including: Relieve pain, maintain digestive health, maintain blood sugar levels, etc. In Malang, chili prices fluctuate, so the price of chili is difficult to predict. This makes the government worried in maintaining the stabilization of chili prices so that they remain affordable and the chili price inflation in Malang City will be good. In this research, several prediction processes were carried out, including, consisting of pre-processing, data normalization, training and prediction using the Long Short-Term Memory method, and error results using the Mean Square Error (MSE). Based on the tests that have been done using daily data on cayenne pepper prices from January 1 2021 to July 31 2022 in Malang City using the Long Short-Term Memory method, the smallest MSE result is 0.0155 with a proportion of training data and testing data of 70%; 30%, with 21 sequence data, 128 hidden units and 150 epochs.

Abstract

The shift in consumer spending to digital has also fueled the growth of online businesses, one of which is online resellers. It is clear from the Central Statistics Agency (BPS) that in 2020 there are 2.36 million companies engaged in e-commerce across the country. Of these, 1.77 million companies (75.15%) are located in Java. Evermos is a platform that connects brands and retailers to sell the best authentic Indonesian products. Therefore, the researchers evaluated the user experience aspects using the meCUE survey method on the Evermos app to identify which apps need improvement from a user experience perspective. The purpose of testing with the MeCUE questionnaire is to find out the advantages and disadvantages of the application under study. The MeCUE study is divided into 4 modules, each discussing product attributes (usefulness, usability, visual aesthetic, status, commitment), user sentiment (positive and negative), and consequences (product loyalty and intention to use), the last one concerns general evaluation product. The EVERMOS application evaluation results for all modules 1 to 4 of the EVERMOS application get the best usability rating or 80. The lowest test score is an indicator of negative emotions, which is 2.00. The results that can be used as a comparison when repairing applications are found in module IV, namely the Intention to Use indicator which gets a value of 3.00. This shows that this application is less attractive among users to use it every day.

Abstract

Plagiarism is an academic violation that is quite serious so that the process of examining plagiarism is one of the prerequisites that must be carried out by academics in making a scientific paper including thesis. Advances in information technology make manual plagiarism checks increasingly difficult. Therefore, technological assistance that uses artificial intelligence is needed to be able to get comprehensive plagiarism analysis results. Turnitin is a software that uses artificial intelligence to detect plagiarism which is very popular and widely used by various institutions around the world. In the Faculty of Computer Science, Universitas Brawijaya, there is a policy that regulates the use of Turnitin to examine student thesis where supervisors play an important role in this policy. Therefore, a study was conducted to analyze lecturers' perceptions of the policy of using turnitin to detect student thesis plagiarism using qualitative methods. In the data collection process, semi-structured interviews were conducted involving 7 thesis supervisors as resource persons. The qualitative data that has been obtained from the interview process is then processed using the thematic analysis method with the help of NVivo software. From the analysis process, two main themes were found, namely the theme of the lecturer's perception of the use of Turnitin with 5 categories and 15 codes and the theme of the lecturer's perception of the policy of using Turntin with 3 categories and 15 codes.

Abstract

Daphnia are a good natural food source for freshwater fish larvae or fry. Daphnia sp. had a protein content ranging from 42-54%, a fat content ranging from 6.5-8% of dry weight, and linoleic and linolenic fatty acids ranging from 7.5 and 6.7%, respectively. Testing the quality of the water where Daphnia lives is something that needs to be considered so that the Daphnia product is good. Water quality parameters that need to be monitored are, for example, temperature and pH. Therefore, research is needed that can facilitate testing the quality of Daphnia culture water. Namely the Daphnia culture water quality test system. The method used is fuzzy sugeno to determine the value of water quality based on the parameter values given by the ds18b20 temperature sensor and 4502c ph sensor. The test produced by the ds18b20 temperature sensor has an average error value of 0.88%. by comparing 9 samples, three of cold water, three of normal water, and three of hot water, to a digital thermometer. For testing the ph sensor has an average error result of 9.5%. By testing using 5 different types of water, namely: well water, pond water, pH buffer 4 water, pH buffer 7 water, and pH buffer 9 water compared to digital pH. Testing the fuzzy method produces an average error value of 2,89%.

Abstract

A wireless mesh network is a network,consisting of,a collection of wireless nodes that are connected to each other and then form a distributed network. Advantages of,wireless mesh network itself, namely in terms of flexibility, scalability and robustness, it is better than other conventional wireless networks. Characteristics Wireless mesh network It is also different from other ad hoc networks, which can be seen from the multi-hoop system, which can make connectivity capabilities in the network faster. In a plural environment, the connection is usually very constrained due to various factors such as trees, fog, and geographical conditions. In the research that has been done, the results show that the OLSR routing protocol has the best results for use on wireless mesh networks compared to other routing protocols on throughput and delay parameters. This research discusses the effect of constant and variable package delivery on a wireless mesh network using the OLSR routing protocol. The test scenario is carried out by changing the number of active nodes, namely 30, 25, 20, 15, 10, and 5, with QoS testing parameters including throughput, end-to-end delay, and packet loss. The best results of the throughput test were obtained from constant packet delivery in the scenario of 15 nodes with 206.43 kbps, which means it has a bad category, so there must be a limit on bandwidth to maintain the performance of the wireless mesh network. The best end-to-end delay test results were obtained for constant packet delivery in the five node scenario with 11867 ms, which means it has a bad category and will affect the performance of a wireless mesh network. The best test results for packet loss obtained from variable packet delivery in the scenario of 10 nodes were 63.466%, which means it has a bad category and affects the performance of the wireless mesh network because too much data is wasted.
