Abstract

Inventory is the process of procurement and inventory of goods owned by an office or company in carrying out operations, whether used in the future or a certain time period. An asset is an item that has economic value, economic value, use value, property value and special value that is owned individually or by a group that is focused on achieving organizational goals. Inventory is very important for the continuity of a company or agency, therefore a system is needed to manage office inventory data. STMIK Kreatindo Manokwari is one of the campuses in the city of Manokwari which has facilities and infrastructure that have not implemented technology-based inventory of goods, inputting data or assets is still done manually using Microsoft Excel, making asset data collection and archiving asset data less effective because it takes time old and unintegrated data collection which results in frequent duplicate data. Based on these problems, a website-based inventory information system was built using the waterfall method as a system development method which was carried out sequentially starting from analysis, design, coding, testing and supporting stages. The result of this research is a system that can make it easier to collect data on goods, check goods or move goods, which can be accessed anywhere and at any time if connected to the internet.

Abstract

Automated text summarization is a method for retrieving the essence of one or more text documents. Automatic Text Summarizer is needed for a faster and more efficient process of reading, searching, and understanding information. This study proposes the Maximum Marginal Relevance method to carry out the text summarization process automatically. The method was developed and tested on each of the 150 Indonesian article documents. The summary is generated from the similarity score between sentences calculated using cosine similarity. MMR's performance in producing summaries was evaluated using ROUGE (Recall-Oriented Understudy for Gisting Evaluation), which compares them to gold-generated summaries. Test results for a compression rate of 50% gave F1 scores on ROUGE-1, ROUGE-2, and ROUGE-L at 71.86%, 64.18%, and 71.56%, respectively. In comparison, the test results with a compression rate of 30% produced F1-scores for ROUGE-1, ROUGE-2, and ROUGE-L, respectively 62.95%, 53.61%, and 62.47%. Compared to previous studies, this study produced better scores.

Abstract

It is important to safeguard personal information captured by the device being used against theft or unauthorized use, which makes network design that is more resistant from hacking attempts. This includes personal information within the ecosystem of smart homes. A house that should be the most comfortable place should not be disturbed because of the wrong configuration of the smart home ecosystem. Several previous studies have discussed security configuration gaps in network infrastructure, but have not focused on the smart home ecosystem from the user's internal side. Therefore, in this research, a 2.4 GHz wireless network configuration testing model is proposed in a smart home ecosystem using an application developed specifically for checking misconfiguration security gaps, which is expected which is expected to expand research on network infrastructure security gaps based on the NIST 800-115 framework. The application's testing technique can reveal details about a wireless network ecosystem's safe and risky conditions. The results of these findings will provide recommendations to wireless network owners to take action to reconfigure their wireless networks to make them more secure.

Abstract

Augmented Reality is a system or form of technological progress and has been used in several things in life. The application of Augmented Reality as a media to support work and learning has been widely used. The use of Augmented Reality technology as a learning medium can support visualization in the field of elementary school education, especially in information and communication technology lessons or what is often known as ICT subjects. The application, called "Augmented Reality Information and Communication Technology" (ARTIK), was developed with the aim of attracting elementary school students' interest in supporting ICT learning, especially understanding computer hardware. This game application was created using the Unity 3D tool and using the Android operating system on a smartphone, as well as utilizing the Vuforia library as an Augmented Reality implementation module. The testing method used is the black box testing method, where the ARTIK application can display 3-dimensional objects on the smartphone well and clearly. Apart from that, ARTIK also has a learning feature with animation and a quiz module to assess how well the learning material is absorbed. The ARTIK learning educational application can be used by elementary school students as a support for learning ICT courses to better understand what hardware looks like using Augmented Reality technology.

Abstract

Cholesterol is a type of fat that circulates in the bloodstream and has an important role in body functions. However, excess cholesterol levels can cause various problems in the body that interfere with the heart, blood vessels, and brain systems. Simvastatin is a lipid-lowering drug in the blood that can reduce cholesterol. In this study, an adverse event was conducted which is an unwanted event in the world of health in the consumption of simvastatin drugs using the Equivalence Class Transformation (ECLAT) algorithm. The data used came from the Food and Drug Administration (FDA) which amounted to 22560 data. Data is managed by the Knowledge Discovery in Databases (KDD) process which goes through several stages, namely data selection, data processing, data transformation, and data mining. Test results are measured based on the lift ratio value which aims to measure the validity of the resulting rule. The test was conducted using a minimum support value of 0.001 and obtained the best lift ratio value of 886.00. In the combination of 2 items, the best rule is "if the duration of therapy is 98 months, it results in acute kidney injury" from 1451 rules with a processing time of 2.70 seconds. The combination of 3 items produces 39 rules with a processing time of 4.46 seconds with the best rule being "if the duration of therapy is 142 months and indicated ill-defined disorder then results in increased blood creatine". The combination of 4 items only produced 18 rules with the best rule being "if sex f, duration of therapy < 1 month and indicated abnormal coronary arteriogram then resulted in anaphylactic shock" in a processing time of 3.45 seconds.

Abstract

The stomach is one of the essential organs of the human digestive system. If the stomach organ cannot work typically, it will cause problems. This is a disease that occurs in the stomach organs. Gastric disease also occurs due to a lack of knowledge about stomach disease, so people ignore the symptoms that arise. Gastric disease is a disease that is considered very serious. If left alone, it can cause other diseases to occur. Generally, finding out the presence of stomach disease is still done manually, and several tests are carried out when stomach disease has recurred. Gastric disorders were classified using 360 iris images taken manually via a digital camera and a web database of iris images. The author used the Radial Basis Function Neural Network (RBFNN) method to classify iris images of patients with gastric disorders in this study. The results obtained from this research can organize the iris images of people with gastric disturbances. Classification of iris images of patients with gastric disorders achieved a training accuracy rate of 65.00%.

Abstract

2024 will be an important year in the history of democracy in Indonesia, as the general election will be held that year to determine the new face of the government. Therefore, this election activity involves many parties, including the General Election Commission (KPU). To carry out all of these tasks efficiently, the KPU requires the support of many supporting personnel. In preparation for this election, the KPU held a selection of the Election Committee (PPK) reception, especially the KPU of Sukabumi Regency. In determining the candidate employees who will be accepted as PPK in each previous event, they still use manual methods, which reduce the effectiveness in choosing candidate employees. One solution to overcome this problem is to require a personnel recruitment decision support system that can facilitate the Sukabumi Regency KPU in determining the candidate employees who will be accepted according to the predetermined criteria. Based on the explanation above, the results of this study are that the Sukabumi Regency KPU has a decision support system application for the selection of PPK reception using the weighted product method.
