<![CDATA[One of the causes of the large number of forest and land fires in Riau Province is human intent to divert forest functions, so that hotspots appear in areas that have the potential for forest and land fires. The purpose of this study was to simulate forest and land fires that occurred in Riau Province using Cellular Automata by utilizing satellite imagery. Land in Riau Province is divided into 5 states, namely: dry land, wet land, land that is being burned, land that has been burned, and land of water. The method used for simulating forest fires is the Cellular Automata to simulate the movement of fire during a fire. This method is able to explain the pattern of fire spread of the main cell fire from neighboring cells. At the end of the study, the simulation results and the movement of fire from where the hotspots appear on satellite images of Riau Province will be shown according to the state of the land cover. The results of this study are a description of the real situation of fires that occurred in Riau Province based on the emergence of hotspots and their movement patterns.]]>

<![CDATA[Student work readiness is quite influential on the existence of a university. The waiting time required by students to get a job can affect the mentality of students and the value of higher education from the assumptions of society. This will greatly affect the interest of parents or prospective students to continue their education at universities that have a bad image. Therefore, predictions of student work readiness before graduation are needed for consideration by higher education institutions to overcome the problem of waiting time for student work after graduation. The source of this research data is obtained from the Surakarta University database by utilizing alumni data from tracer studies as train data and 6-semester active student data as test data. The initial step taken is preprocessing to eliminate noise that can interfere with or affect the final result. The research method that will be used is to implement the K-Means and C4.5 algorithms for grouping and prediction processes. The data train used is 150 data and the testing data is 59 data. The results obtained by the K-Means algorithm can cluster 143 data correctly by comparing with the original data. The best cluster value obtained is K = 3. ]]>

<![CDATA[Bell’s Palsy is paralysis of the facial muscles that causes one side of the face which causes one side of the face to sag. In Indonesia, there are many cases of bell's palsy but it is definitely difficult to determine. In this case, there was a case of bell's palsy in Indonesia of 19.55%, from all the most frequent cases of neuropathy that were found in the age of 20-50 years, and the incidence increased with increasing age after 60 years. About 60-85% of sufferers can recover completely within 3 weeks and only 15% require 3 months. But there are 30% of those who have a lifetime disability due to the patient not getting better for 4 months. Therefore an expert system was designed to diagnose bells palsy. The method used in the expert system is the Tsukamoto Method. The Tsukamoto method is a development of the Mamdani and Sugeno methods which use control and are also used by humans instead of machines. Fuzzy Tsukamoto is one method that is very flexible and has a tolerance for existing data. This expert system can provide solutions and ways to prevent bell's palsy with the diagnosis process carried out efficiently and save time in helping the general public in the prevention that occurs. This web-based expert system application was built with the PHP programming language and MySQL data storage]]>

<![CDATA[Infrastructure development is one of the fundamental elements to accelerating regional and national growth. The government is in charge of infrastructure development as a way to give the residents of Dumai City the best services possible. Infrastructure like transportation, telecommunications, sanitation, and energy availability cannot be isolated from a country's or region's rate of economic growth and investment. It also has a significant impact as one of the forces driving economic expansion, which is the cornerstone of long-term economic prosperity. This study aims to gauge community satisfaction with the current road infrastructure in Dumai City in addition to bringing the Dumai City Government's attention to damaged road infrastructure. Data was gathered using a Google form-based smartphone application, and IBM SPSS Statistics version 26 was used for analysis. For the research sample in this study, 100 samples of respondents were chosen. Due to the Dumai City Government's lack of attempts to repair damaged roads, the community is dissatisfied with the road infrastructure, according to the study's findings.]]>

<![CDATA[The Joint Selection for State University Entrance (SBMPTN) is a very important moment for prospective students to enter the world of lectures. This selection path is the biggest and most attractive opportunity for prospective students to be able to enter State Universities (PTN). SBMPTN is a selection route that is held openly and uses a written test-based selection. Prospective students need to prepare everything carefully to take part in the SBMPTN selection. When the SBMPTN registration was opened, the burden on the guidance and counseling teacher at SMA 1 Lubuk Alung became heavy because many students consulted the counseling teacher to provide input for students manually, namely comparing student grades with the majors of interest. For this reason, a Decision Support System (SPK) is needed to assist schools and BK teachers in determining the priority of majors on the SNMPTN pathway. DSS is used as an alternative in decision making, DSS utilizes data and models to solve unstructured problems, one of the models used in DSS is the Simple Multi Attribute Rating Technique (SMART). This method was chosen because of its simplicity in the calculation process so as to facilitate system development. This system is web-based so that students can access the web so they can choose their major. With this system, students are expected to be able to choose majors according to their wishes and abilities.]]>

<![CDATA[The human development index is an indicator that can measure the success of a region in developing human quality. The success of human development can be measured by how fundamental problems in society can be overcome, such as poverty, unemployment, and lack of access to public facilities. The increase in HDI in an area can be determined by several factors, including life expectancy (UHH) and the unemployment rate. One of the models that can be used to determine the factors that significantly affect the human development index is logistic regression, where logistic regression is an approach to making a predictive model in the form of the probability of a variable.The data used in this study are HDI, UHH, and unemployment rates in West Sumatra Province in 2019–2021. Based on the multicollinearity test, there is no relationship between UHH and the unemployment rate. This study was conducted to determine the factors that significantly affect the human development index of districts/cities in West Sumatra Province. Based on the results obtained, UHH has dramatically affected the HDI of districts/cities in West Sumatra Province over the last three years.]]>

<![CDATA[In time series data research, it is often encountered the problem of lack of available time and budget. So often found the presence of censored data. Censored data can be analyzed using the partial likelihood method. However, other obstacles will arise if the processed data contains ties. So it is necessary to use other methods that can overcome the co-occurrence. In this study, the Breslow method is used to estimate the censored data due to joint events. This method is applied to the case of patients with burns. The variables used are the method of treatment, gender, race and type of burn. The results of the analysis showed that race did not give a significant difference to the incidence of cutting burned organs. While the other three variables showed significant differences at the 95% confidence level. The results of the analysis using the Cox proportional hazard method showed that patients treated with the body cleansing method had 17% greater risk of cutting than those treated with the body routhine bathing. ]]>

<![CDATA[The problem The with development projects is to determine the project schedule so that it can be completed in an optimal (minimum) time. Scheduling with Network, among others, uses the CPM (Critical Path Method). The network diagram representation of the method is in the form of a directed graph (digraph) which is presented in two models, namely AOA (Activity On Arc) and AON (Activity On Node. Activities in the AON model are placed on nodes. This study aims to determine the application of network analysis using the CPM method. The AON model on the scheduling of the library development project at UIN Malang The methods used are forward pass, backward pass, and total slack so that it can be known the fastest or late time an activity can be started or ended and the amount the allowable delay time for an activity and its critical activities.Previous research only used the PERT (Program Evaluation and Review Technique) method and the Gantt Chart method, so in this study the author will use another method, namely the CPM Model AON method. pen time the construction project schedule is 293 days starting from 01-07-2022 to 27-05-2023. From the results of the analysis using the CPM method, it was obtained that from 298 project preparation activities, 17 activities were critical activities so that their implementation could not be delayed because it would result in a delay in project completion time.]]>
