<![CDATA[Measles is an infectious disease that often occurs in children and is caused by the measles virus (morbillivirus) which can cause death. Thus, it is important to identify the factors that cause measles. The number of measles cases is used as response variable in the form discrete data so that Poisson Regression is commonly used. However, some assumptions are sometimes not met, such as overdispersion and excess zero so that can use Zero Inflated Poisson Regression to meet these assumptions. Because the model can overcome two common characteristics that are often found in count data, which are excess zero and overdispersion. The purpose of this study was to determine the factors that influence the number of measles cases in East Java. The data in the study used secondary data obtained from the Central Statistics Agency (BPS). The predictor variables used were the number of population, percentage of vaccination, percentage of poor people, and percentage of adequate sanitation. The results showed that the data is overdispersed because the variance is greater than the mean. There were four predictor variables, The -value of the total population variable is <0.01, the percentage of vaccinations is 0.914, the percentage of poor people <0.01 and the percentage of proper sanitation is 0.014 so it can be concluded that the percentage of vaccinations has no effect on the number of measles cases and the other three variables affect the number of measles cases in East Java. The best model of affect the number of measles cases in East Java is Zero Inflated Poisson with AIC value 326.24. The ZIP model for measles case in East Java is .]]>

<![CDATA[Logistic path analysis is used to analyze direct and indirect causal relationships between exogenous-endogenous variables with categorical data types. This study aims to apply logistic path analysis to ordinal categorical data and model the relationship between exogenous variables that affect nutritional status and physical status (stunting) in toddlers in Sumberputih Village, Wajak District. The data used is secondary data obtained from the results of filling out questionnaires in Sumberputih Village at the time of data collection in 2022-2023. The sample used in the study was 100 housewives who had toddlers. The sampling technique used was judgment sampling. However, the study only selected the variables of Birth Weight, Dietary Habits, Nutritional Status, and Physical Status (Stunting). The result of this study is that the variable of Birth Weight has a significant direct effect on Nutritional Status. The variable of Birth Weight has an indirect effect, and the total effect on Physical Status (Stunting) mediated by Nutritional Status is not significant. Meanwhile, the Diet variable has a significant direct effect on Physical Status. In addition, the Socioeconomic Condition variable can moderate the relationship between the Birth Weight variable and Physical Status. The diversity of data that can be explained by the model is 80.36%, while the rest is explained by other variables outside the model by 19.64%.]]>

<![CDATA[Background Many students struggle to understand complex academic material, which negatively impacts their academic performance Purpose This study aims to examine the influence of psychomotor and cognitive aspects on the academic achievement of management students at Muhammadiyah University of East Kalimantan. Design/method/approach This study uses a quantitative research design. Data were collected through structured questionnaires distributed directly to the selected students, as well as documentation of their academic records. The sample of 180 students was determined using the Slovin formula and selected by random sampling from a total population of 328 students. The collected data were analyzed statistically using SPSS 27 software, employing classical assumption tests, multiple linear regression, and hypothesis testing to assess the relationship between cognitive factors and academic achievement. Results The analysis revealed that cognitive aspects have a significant positive influence on the academic achievement of eighth-semester management students at Universitas Muhammadiyah Kalimantan Timur. Students who demonstrated stronger cognitive skills—such as critical thinking, understanding, and the ability to analyze material—tended to achieve higher academic performance, as reflected in their GPA and other academic indicators. The statistical results from multiple linear regression showed that the cognitive variable contributed meaningfully to variations in students’ academic success. These findings suggest that efforts to enhance cognitive abilities among students can lead to improved academic outcomes in higher education settings. Contribution/value This study provides valuable insight into the specific role of cognitive aspects in shaping academic achievement among eighth-semester management students at Universitas Muhammadiyah Kalimantan Timur.

<![CDATA[Peramalan adalah teknik penting untuk mengestimasi nilai masa depan berdasarkan data historis. Namun, metode peramalan sering menghadapi tantangan dalam memilih model dengan tingkat akurasi terbaik. Penelitian ini bertujuan membandingkan kinerja metode Jaringan Syaraf Tiruan (JST) dan Fuzzy Metode Sugeno serta gabungan kedua metode yang disebut Adaptive Neuro Fuzzy Inference System (ANFIS). Ketiga metode digunakan untuk meramalkan inflasi bulanan Indonesia. Penerapan ketiga metode membutuhkan penentuan input yang berdasarkan stasioner dan PACF. Data tidak stasioner lag 2 sehingga Differencing lag 2 kemudian tidak ada lag yang keluar pada PACF. Berdasarkan kedua hal tersebut ditentukan inputnya ialah dan . Hasil menunjukkan bahwa metode JST dengan 3 lapisan tersembunyi dengan banyak neuron (2,1,1) memberikan kinerja terbaik (nilai RMSE terkecil sebesar 1,16127 pada data testing). Metode terbaik tersebut digunakan untuk meramalkan Inflasi bulan September 2023 hingga Desember 2024 cenderung konstan antara 2,68879% hingga 2,68887%. Kontribusi riset ini adalah metode advance (ANFIS) dengan menggabungankan dua metode (JST dan Fuzzy) belum tentu lebih baik daripada metode tanpa penggabungan (JST atau Fuzzy). Abstract Forecasting is an important technique for estimating future values based on historical data. However, forecasting methods often face challenges in choosing a model with the best level of accuracy. This study aims to compare the performance of the Artificial Neural Network (ANN) and Fuzzy Sugeno Method methods and a combination of the two methods called the Adaptive Neuro Fuzzy Inference System (ANFIS). The third method is used to predict Indonesia's monthly inflation. The application of the third method requires input determination based on stationary and PACF. The data is not stationary lag 2 so that Differencing lag 2 then there is no lag that comes out in PACF. Based on these two things, the input is determined to be Y_(t-1) and Y_(t-2). The results show that the ANN method with 3 hidden layers with many neurons (2,1,1) gives the best performance (the smallest RMSE value is 1.16127 on the test data). The best method used to predict inflation from September 2023 to December 2024 tends to be constant between 2.68879% to 2.68887%. The contribution of this research is that the advanced method (ANFIS) by combining two methods (ANN and Fuzzy) is not necessarily better than the method without combining (ANN or Fuzzy).]]>

<![CDATA[The main problem in this study lies in the imbalance of workload, especially in the distribution of tasks in the work environment. This imbalance causes some employees to experience fatigue due to excessive workload, while others lack responsibility. In addition, problems also arise in aspects of the work environment, especially related to the instability of working time caused by the limited number of workers. This condition hinders work flexibility and reduces opportunities for interaction between teams, which in turn has the potential to reduce overall organizational effectiveness. This study aims to analyze the effect of workload and work environment on employee performance at the Regional Inspectorate of East Kalimantan Province. The research method used is a quantitative approach with multiple linear regression analysis techniques, using the help of SPSS software version 29. This analysis is complemented by validity, reliability, and classical assumption tests, which include normality, multicollinearity, and heteroscedasticity tests. To measure the influence on variables, a partial test (t test), simultaneous test (F test), and calculation of the coefficient of determination (R²) are used. The results of the study stated that: (1) Workload has a positive and significant effect on employee performance. (2) The work environment has a positive and significant effect on employee performance. (3) Workload and environment together have a positive and significant effect on employee performance at the Regional Inspectorate of East Kalimantan Province.]]>
