Abstract

The website is one of the information service systems needed by the community to carry out various public service activities. It's just that it is necessary to do a word-checking process on the website to avoid swear words, especially on government service websites. Checking swear words on the website takes a long time, done by reading every website content that the admin will add. So we need a system that can check swear words on the website. The purpose of the research is to simplify detecting swear words on the SKPD website. In this study, a system was designed and built that can detect swear words when the admin adds and changes website content and validates criticism and suggestions that visitors have added by implementing text mining. This study uses the Nazief and Adriani algorithms for the stemming process and the Term Frequency algorithm for the weighting process. The test method used is accuracy measure. From the test results, the accuracy value is 88%, precision of 78.57%; recall of 100%; and f measure by 88%. The results obtained have not been maximized because the system has not been able to read the sentence structure, so that a word that should not be used as a swear word in a document/text becomes detected by the system as a swear word, for example, the word dog detected in the text of the news about rabid dogs.

Abstract

Breastfeeding is a special and joyful event that most mothers and their babies experience. Exclusive breastfeeding (breastfeeding only for babies until they are six months old) is an activity that is very beneficial for both mother and baby. The low achievement of exclusive breastfeeding often begins with giving prelacteal intake in the first days of the baby's life because of the low understanding of the baby's mother about the importance of breastfeeding. This study links the relationship between breastfeeding self-efficacy and prelacteal feeding in the first week of birth. This type of research is correlational with a cross-sectional approach. The population in this study were breastfeeding mothers in the first week of the baby's birth; the number of samples was 50 people with purposive sampling technique. The data was collected using the BSE-SF questionnaire and observation—data analysis with univariate and bivariate chi-square tests to determine the relationship between the two variables. The study results with a p-value of 0.000 0.05, so it was concluded that there was a relationship between breastfeeding self-efficacy and the provision of prelacteal nutrition in the first week of birth. This research can then be used to reference further breastfeeding guidance strategies.

Abstract

The Covid-19 outbreak has changed the learning system in Indonesia into distance learning, better known as online learning. In determining student learning outcomes on student learning satisfaction with distance learning during the Covid-19 pandemic, a study was carried out using the Simple Additive Weighting (SAW) method. This study aims to determine student learning outcomes during the Covid-19 pandemic. The type of research used in this research is applied research, in which this research is directed to obtain information that can be used to solve problems. The method used is Simple Additive Weighting (SAW) by comparing the results of the decision of the SAW method between the weighting based on the Fuzzy Logic method and the weighting based on the ROC method. The subjects involved in this study were 36 students of Vocational High School (SMK). Data collection in the study was carried out using direct observation, interviews, and questionnaires. The criteria contained in the questionnaire are factors that affect the process of student learning outcomes on learning satisfaction during the Covid-19 pandemic. The criteria used are device ownership, accessibility, ease of obtaining materials, method accuracy, monitoring ability, interactivity, and independent learning. From the seven criteria, the priority scale is determined. The results showed that the analysis of the search for weight scores using the Simple Additive Weighting (SAW) method using Fuzzy Logic and Simple Additive Weighting (SAW) using the Rank Order Centroid (ROC) method resulted in different sub-criteria weighting scores, so it can be said that the combination of SAW- ROC provides a more accurate and more selective selection of the number of students.

Abstract

The low level of public awareness of environmental cleanliness has led to the spread of dengue hemorrhagic fever (DHF). This study aims to identify and analyze the factors that cause dengue hemorrhagic fever (DHF) using the Chi-Square Automatic Interaction Detection (CHAID) method. This type of research is applied research, namely research conducted to apply, test, and evaluate the ability of a theory that is applied in solving practical problems. This research was conducted at the University of Kaltara by taking quantitative data on dengue hemorrhagic fever (DHF) patients recorded at the Bulungan District Health Office. The analytical method used is the Chi-Square Automatic Interaction Detection (CHAID) tree-structured classification method with the Statistical Package for the Social Sciences (SPSS) program. Based on the study results, it was found that five factors caused the occurrence of dengue hemorrhagic fever (DHF) in Bulungan Regency. They are Gender, Age, Work Status, Environment, and Household Income. Based on the CHAID analysis using the IBM SPSS Statistics computer program, a decision tree is formed, which consists of 5 nodes consisting of 1 main node (node 0), one decision node (node 1), and 3 terminal nodes (node 2, 3 and 4). The predictor variables that affect the formation of the decision tree are Age and Household Income. DHF patients can be classified into three different segments from the segmentation decision tree with an estimated risk of 0.273, which means the risk of the wrong classification for DHF status is 27.3%.

Abstract

Fish drying by using additional salt as a preservative and adding flavor to the fish. This study aims to determine the effect of various doses of salt on the quality of tilapia, motan, dried salted lemongrass and the difference that does not use salt on the quality of fish. This type of research is quantitative research with experimental methods. The independent variable in this study was the concentration of NaCl salt as a treatment, namely 10%, 20%, 30% of the total fish weight. The controlled variables of this study were the type of fish, weather conditions, and materials used. The research process begins with weeding motan, tilapia, and lemongrass fish, namely motan fish, tilapia, and lemongrass fish, weighing 100 grams. Then the fish are weeded with running water, removed all the contents of the fish's stomach, and drained until the fish does not contain too much water. Then the addition of salt to the motan fish, tilapia, and lemongrass fish has been given, namely, 27%, 34%, and 41%. The duration of soaking or salting is 24 hours. After the salting time has been completed, the fish drying process is continued. The fish dried at a temperature of 30C to 35C for 2 to 3 days to obtain the desired characteristics of salted fish. Data was collected by testing the salt content in fish with different concentrations. The results showed a difference between salted fish and unsalted fish. Salted fish has a harder texture, taste better, and have a longer shelf life.

Abstract

Drying fish is one way of preserving fish by reducing the water content so that the activity of microorganisms can be reduced. Preservation by drying is intended to extend the shelf life of fish. The method used in this research is using the experimental method. The data used in this study include data regarding the process, what materials will be carried out in this research. In this study, there were several problems in the drying time of fish. The data collection technique was the implementation of experiments and documentation. The conclusion of this research is sunlight, fish thickness, and drying time affect the drying rate of fish. Fish that get enough sunlight and have a small and thin shape will dry faster than fish with thick meat, such as catfish and catfish. Fish dried without salt and get enough sunlight will usually dry faster than fish given salt. Except for fish that have thick and oily meat usually dry longer. The drying time of fish varies depending on the thickness of the fish and the sunlight it gets.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan evaluasi serta perkembangan yang terjadi atas pelaksanaan kebijakan pelaksanaan program Pemberdayaan Ekonomi Masyarakat Pesisir (PEMP) di Dusun Taman Desa Taman Ayu Kecamatan Gerung Kabupaten Lombok Barat Tahun 2015. Metode yang digunakan adalah metode penelitian deskriptif dengan pendekatan kualitatif, pengumpulan data menggunakan wawancara, pengamatan yang sudah dituliskan dalam catatan lapangan, dokumen pribadi, dokumen resmi, gambar, foto dan sebagainya. Sedangkan analisis data menggunakan metode model alir (flow model) yang meliputi tahap: (a) reduksi data, (b) penyajian data, dan (c) penarikan kesimpulan serta verifikasi. Berdasarkan hasil penelitian dan pembahasan terhadap fokus permasalahan dalam penelitian ini, maka dapat diambil beberapa kesimpulan sebagai berikut: (a) Pelaksanaan kebijakan PEMP  dalam pemberdayaan masyarakat miskin di Kecamatan Gerung terdiri dari empat tahap, antara lain yaitu tahap persiapan; tahap pelaksanaan; tahap pengendalian; dan tahap pelestarian. Pemanfaatan dana bantuan telah sesuai dengan tiga komponen kegiatan yang menjadi sasaran tujuan program PEMP, yaitu ekonomi produktif; pelatihan dan pembangunan sarana dan prasarana dasar lingkungan. Namun masih ada sejumlah anggota KSM yang memanfaatkan bantuan tersebut untuk kegiatan konsumtif. Pembentukan BKM dan KSM dilaksanakan secara demokratis, transparansi, dan jujur, karena kedua lembaga lokal inilah yang berinteraksi dalam pelaksanaan PEMP.
