Abstract

One of the declining levels of corn production is caused by the presence of disease. In addition, the delay in handling due to the lack of experts in the Kutacane area itself, so that it can affect the decline in plant production levels. Therefore, an application is needed to diagnose diseases in corn plants using expert system rules in decision making. In making this web-based expert system application using the KNN (K-Nearest Neighbor) algorithm, where the K-Nearest Neighbor algorithm is an approach to finding cases by calculating between new cases and old cases, which is based on the leakage of weights from a number of existing features. which can provide convenience in conducting consultations like an expert. This application serves as a tool to identify types of diseases in corn plants and how to overcome them. Users can only input the symptoms experienced by the system, then the system will provide output in the form of types of corn plant diseases and provide solutions based on similarities in previous cases. From this task, the final result can be known the results of the diagnosis of diseases in corn plants through a consultation process quickly and efficiently.

Abstract

Stunting is still a serious public health problem in Indonesia, where the prevalence of this condition is 37.2%, up from 35.6% in 2019 and 36.8% in 2020. The length or height of a child who is short (dwarf) is below average for his age. Stunting has a negative impact on IQ deficiencies, infectious diseases, mental health problems, and child development. Toddlers with stunting cases are detected when their growth and development does not match their age, but currently there is no data grouping based on these criteria that is of concern to parents and posyandu cadres. Data can be grouped using the K-Means data mining technique. The K-Means algorithm is often used by researchers as a grouping procedure to ascertain whether children are stunted or not. 395 datasets are used in this research data. The Knowledge Discovery In Databases (KDD) approach, a comprehensive nontrivial procedure for detecting and recognizing patterns in data, underlies this research. Based on the variables of age, weight and height, this study aims to identify groups or clusters of stunting status in children under five. The best number of clusters with K = 2 was determined by the findings of this investigation. There are 392 children in cluster 0-Shanum, Rizka, Nurjanah, and others-and three toddlers in cluster 1-Ezra, M. Abidza, and Abd Mahmud. With a total of 287 stunted toddlers and 108 toddlers with normal development, the most ideal DBI value is 0.007 which is close to 0, this shows that the clusters under review provide quality clusters.

Abstract

In the process of administrative modernization, it is necessary to implement an information system that can support all administrative activities in an institution, institution or company. At the Tano Tombangan Angkola District sub-district office, South Tapanuli, there is still a conventional letter archive management method where archive recording is still done using books and stationery. This often causes many problems, such as lost documents, damage or unrecorded documents. In this research, the authors try to develop an application that can record all archives in the agency. Then it will be stored in the database and can be accessed anytime and anywhere. As a result, many benefits are provided to agencies, such as more structured and neat archival data collection. The management system created in this paper is Web-based using PHP.

Abstract

Untuk membangun table routing, setiap routing protocol menjalankan algorithma routing, algorithma routing inilah yang mengatur proses kerja dan karakteristik kerja dari sebuah routing protocol. Jika dikelompokkan berdasarkan algorithma routing yang digunakan maka  protokol routing terbagi menjadi 2 bagian kategori besar yaitu vector routing protocol dan link state routing protocol. Permasalahan terjadi ketika administrator jaringan seringkali kesulitan untuk menentukan jalur terpendek dari sebuah topologi jaringan, protokol routing link state menggunakan algorithma routing SPF (Shortest Path First) atau sering disebut djikstra, memungkinkan pencarian jalur terpendek dari sebuah topologi jaringan untuk mencapai remote network. Dalam mencapai path terpendek algorithma SPF tidak menggunakan jumlah lompatan (houp count) namun algorithma ini menggunakan cost kumulatif dari setiap link antar router untuk mencapai suatu remote network.

Abstract

Processed products of palm sap are cooked for a certain duration of time to produce brown sugar. In general, the community still uses coconut/aren sap water as a raw material for making brown sugar, but currently residents of Pasar Eight village in Air Putih sub-district have made brown sugar using waste palm stems to get the sap water and then mix it with white sugar. The purpose of community service is to increase online marketing and provide education on making brown sugar that is correct and good for health. Brown sugar has its own advantages, but improper processing can harm health in order to gain unilateral benefits. Based on the results of observations when visiting brown sugar craftsmen (partners), information was obtained that the marketing of palm sugar palm sap was carried out online through social media face book and product orders had reached the Pekanbaru area, although not routinely. Therefore community service is carried out by providing outreach to brown sugar craftsmen in order to expand the marketing network which will increase sales, production and profits so as to open jobs for the community. The service method is carried out by observing and interviewing and outreach. It is hoped that the results of PkM activities can increase the knowledge of brown sugar craftsmen about online brown sugar marketing and the quality of brown sugar production and hygiene.

Abstract

The HIV (Human Immunodeficiency Virus) is an infection-causing virus that targets the immune system, making it more vulnerable to illness and infection. East Java (33,043), Papua (25,586), West Java (24,650), and Central Java (18,038 persons) all had more HIV/AIDS infections in 2017 than DKI Jakarta (46,378), which was followed by East Java (33,043), West Java (24,650), and a smaller number—25,586—in Papua. Nationally, West Java is still among the four provinces with the highest HIV/AIDS cases. This shows that HIV/AIDS has become a threat to the wider community because in addition to threatening the lives of sufferers, this disease is at risk of transmission that will increase. The increase in HIV/AIDS cases can be a problem in the psychology of the sufferer, because this disease can have a negative impact in the form of physical, psychological, social and spiritual problems that cause PLWHA (People with HIV AIDS) to live a stressful life. In this study, calculations were carried out using the K-Means algorithm with the Optimize Parameters Grid on data on the spread of HIV / AIDS cases in 2019-2021 sourced from the West Java Provincial Health Office. K-Means is one of the algorithms in data mining that can be used for grouping / clustering of data. The data used in this study were 971 records. The purpose of this study was conducted to determine the cluster of t h e spread of HIV/ AIDS as an effort to assist the government in reducing the number of HIV / AIDS cases in West Java province. The results o f this study are comparing DBI with the K-Means method from k-2 to k-20 contained in the table above, it can be seen that the cluster that is close to 0 is k-2, with a DBI value of 0.414. Because the value of k-2 is the smallest value compared to other k, it can be concluded that k-2 with a value of 0.414 which is closest to 0 is the best cluster result.

Abstract

XOR cipher is a message randomization algorithm by performing XOR logical operations for plaintext and key so that it becomes a ciphertext. The problem lies in the predictable use of XOR. Therefore, it uses key security using the Three Pass Protocol. This protocol secures communication for each party. The key used for Three Pass Protocol communication is Base64. The Three Pass Protocol scheme for XOR Cipher key security using Base64 has a weakness because it is due to the Base64 encoding process which by default is easy for others to know. So that this research can be developed again to replace Base64 into a better algorithm in terms of security.
