Abstract

The process of managing incoming and outgoing letters in government agencies is still using a manual system, recording is still using an agenda book which has several problems, such as the difficulty of administrative staff in finding old data due to the accumulation of letter data and the letter archiving process. In this study, a web-based mail archive system & SMS gateway mail archival system was created. This system can assist the process of filing letters. Testing this system using BlackBox testing. The research method uses the waterfall system development technique, consisting of several stages, namely the stages of needs analysis, system design, writing program code, conducting testing, and program implementation and maintenance. The data collection technique used is through the interview, observation, and literature study. The test results of the correspondence information system with features to manage officer data, manage incoming mail data, manage outgoing mail data, manage letter type data, manage travel letter data outside the region, and reports. This shows that the system created can function as expected.

Abstract

Hydroponics is a method of cultivating plants by utilizing water as a growth medium by emphasizing on meeting the nutritional needs of hydroponic plants. Hydroponics requires special treatment such as maintaining nutrient levels within the range so that the use of a control system is used. The implementation of the automatic nutrition control system aims to make it easier for farmers to regulate the mixing of AB mix + POC nutrients with water at the PPM value of lettuce plants automatically based on the age of plant growth, so that farmers can produce plants with optimal growth and maximum yields. The hydroponic nutrition control system uses the Fuzzy method. The system will also be integrated with the Arduino Uno microcontroller which is equipped with a Total Dissolved Solids (TDS) sensor. The results of this study can be seen that the success of the system can work well in detecting nutrients in the reservoir and can control pumps and water pumps in low, normal, and high conditions. The sensor used can also work well, where the TDS sensor has an error value of 4.81% and then calibration is carried out so that it gets the equation for the TDS value

Abstract

Information about consumer spending patterns is needed by retail companies in determining promotion strategies, placing merchandise on shelves, and inventory management. Most applications in retail companies only produce information from the company side. Applications owned by the company have not been able to generate transaction activity information from the customer side. The transaction activity information from the customer side is knowing consumer spending patterns in terms of buying goods. This information can overcome problems that are often faced by companies, namely customer complaints when there is a vacancy in inventory of pairs of goods that are often purchased by customers. This article describes the application of association data mining with the Apriori TID algorithm. Apriori-TID is a development of the Apriori algorithm. Apriori-TID plays a role in finding frequent itemsets based on minimum support. The application can generate goods association rules based on the minimum support and confidence values entered by the user. The association data mining application features dataset import, dataset analysis, and print analysis result reports. The association rules generated by the application are evaluated using the lift ratio method. The number of transactions, minimum support, and minimum confidence affect the number of rules generated by the application.

Abstract

The need for raw water for various reasons, particularly clean water for households, public areas, and industry, will continue to rise as the world's population grows and the pace of growth in various fields accelerates. However, because the existing supply of clean water infrastructure is still limited, it has not been able to cover all of the country's water needs. Residents in Latambaga District, Kolaka Regency, are likewise concerned about the lack of safe water. Although the area has adequate water sources (river water) and a distribution network that distributes clean water to the population, the issue is getting water from these water sources to areas where there isn't an optimal clean water distribution network so that it can be used by the community population. As a result, it is required to assess PDAM Kolaka's clean water distribution network by employing the EPANET program application in its analysis. The findings of the pipeline network evaluation using the EPANET 2.0 application, the diameter of the pipes used in the evaluation, pipes with a diameter of 1" to 4", and the demand for 1,003 rods of PVC pipes

Abstract

There are so many studies that use the Multi-Attribute Decision Making (MADM) method as a solution in Decision Support Systems. In addition, there are also many studies that use additional fuzzy which is implemented in the MADM method which is commonly referred to as Fuzzy MADM. For example, using Simple Additive Weighting (SAW), which one is closer to the best solution, whether to use MADM SAW or FMADM SAW, which one is better to use. Based on these problems, in this study analysis will be carried out regarding which method is closer to the best solution to be implemented in the case of Decision Support System between MADM and FMADM, in this case using the case of selecting the best graduates in the study program and the SAW method. Based on the results of the discussion in this study, it can be concluded that the implementation of MADM uses SAW, with 2 approaches, namely: Likert and fuzzy scales. The results obtained from the comparison of assessment ranges using the Likert and fuzzy scales obtained suitability of 100%. While the results of testing using RSD on Likert and fuzzy scales obtained the same results, namely 12.24%. The use of a Likert scale or fuzzy numbers has no effect, what affects the results is the range of the rating scale.

Abstract

CentOS 8 is a popular operating system for servers, but will discontinue. The Oracle Linux 8 operating system was chosen as a replacement because this operating system has many similarities with CentOS 8 and is distributed by the same party, namely RHEL (Red Hat Enterprise Linux). This study aims to compare the stability of the two server operating systems, as well as provide a reference for operating system users to choose a server operating system. CPU and memory tests were performed using SysBench software with the same number of threads, which were then recorded and compared. Cacti software is also used to compare CPU and memory performance in real time. The results showed that Oracle Linux 8 and CentOS 8 are two operating systems with different variances, although the kernels used by both operating systems are the same. Oracle Linux 8 can serve clients faster than CentOS 8 with a difference of 0.26 seconds.

Abstract

Today's increasingly rapid use of digital technology has created many new opportunities for organizations in all industrial fields. Digital transformation has a positive impact on innovation and company performance based on the theory of the resource-based view. The growth of Small and Medium Enterprises (SMEs) and their relatively high role in the community's economy, is also accompanied by several problems that arise in the face of the current digitalization era. The main challenges in the digitization process for SMEs are limited financial resources, limited knowledge resources, and limited technology awareness. An ecosystem-based digital platform enables SMEs to integrate strategic knowledge sources while configuring internal and external resources to better respond to a dynamic and volatile environment.
