Abstract

Monkeypox is a zoonotic infectious disease caused by the monkeypox virus which belongs to the Orthopoxvirus group. This virus was originally transmitted from animals who innfected with the monkeypox virus to humans, especially rodents and primates. In addition, it can also be transmitted between humans. To make it easier to describe the process of the spread of monkeypox, a mathematical model was created. The mathematical model was made by taking several assumptions based on the nature of charateristics of monkeypox, especially on the pattern of the spread of monkeypox. Based on the assumptions made, this model has two parts to the population, namely the human population is divided into four subpopulations and the animal population is divided in two subpopulations. The model produces a system of non-linear equations that is solved using the Runge-Kutta method of orde 4. The result obtained in this study is a simulation in graphical form. Two simulations were carried out using different parameter values. The parameter is the rate of human infection from animals. The simulation results show that when the value of the human infection rate from animals is reduced, the disease will disappear within a certain time. So that, one of the factor that can be suppressed so that the spread of monkeypox is controlled is the rate of human infection from animals.

Abstract

The Province of East Nusa Tenggara (NTT) is categorized as a lagging region based on the value of Gross Regional Domestic Product (GRDP) and belongs to the lowest group at the national level. This underdevelopment has become a special concern for the government in every work program. This condition is an appropriate reference for periodic analysis in a certain time series. The analysis is carried out in various aspects that are dynamic by paying attention to spatial conditions, because each region has different characteristics. One of the main concerns is the value of GRDP, which is a measure of the welfare of a region. The estimation of the regency / city GRDP value model in NTT Province has been carried out, so the existing model is then used for prediction analysis based on updated real time data which is then mapped to see the distribution of GRDP values as a description of actual conditions. The prediction process is carried out using a method that is able to accommodate the characteristics of spatial data and a combination of time series and cross section data, so the appropriate method is dynamic panel spatial. The prediction results obtained the accuracy value of the Mean Absolute Percentage Error (MAPE) criterion of 7.47%, which means less than 20%, so it can be concluded that the dynamic panel spatial models is the right method to be used to forecasting the value of district/city GRDP in NTT Province for the next period of time. The prediction results obtained by the distribution of GRDP values are divided into four categories, namely low, medium, high and very high, which are marked by different colors on the mapping.

Abstract

East Nusa Tenggara Province has the lowest Gross Regional Domestic Product (GRDP) value in Indonesia. The local governments try to increase the value of GRDP by providing capital for productive businesses, increasing human resources, and managing the economic sector in each district/city. The GRDP value is influenced by dynamic economic factors. In a functional region, GRDP values in a region are correlated with neighboring regions. Regions that have homogeneous characteristics will tend to have the same economic condition, therefore indicating there is spatial dependence. Therefore, to know the pattern of GRDP value should be doing periode observed use panel data. Model panel data that can accommodate the effect of each factor on GRDP value has dynamic and dependence spatial, the model can be more useful to capture them. This study will apply the model to the cast of GRDP value in the district/city of East Nusa Tenggara Province with economic factors affecting GRDP value is labor (L), population (P), investment (Inv), and locally generated revenue (LGR). The results of variable estimated the found that significantly affect the GRDP values are investment (Inv) and locally generated revenue (LGR), furthermore GRDP value affect by GRDP value in the previous period and GRDP value by neighbor regions.

Abstract

The inflation rate in the city of Batam from January 2023 to April 2024 continues to fluctuate, so an accurate prediction model is needed so that inflation control can be carried out optimally. In this study, we conducted a comparative analysis between the Radial Basis Function Neural Network (RBFNN) method and the Autoregressive Moving Average (ARMA) model in predicting the inflation rate. The data used is historical data on the inflation rate of Batam City from January 2009 to April 2024. The results of the analysis show that the RBFN method with an MSE value of 0.239 is able to provide a more accurate prediction compared to the ARMA model (2.3) with an MSE value of 0.246 in predicting the inflation rate in Batam City. This is due to the RBFN's ability to capture complex and non-linear patterns contained in inflation data. In addition, the performance of RBFNN is also affected by the number of neurons and the basis function used. Thus, the results of this study show that the RBFN method can be an effective and efficient alternative in predicting the inflation rate in Batam City.

Abstract

Background: Kegiatan pengabdian ini dilaksanakan bersama mitra kelompok Tani Nunuh Naek yang berlokasi di Desa Napan Kab.TTU, dengan jumlah anggota sebanyak dua puluh orang. Wilayah pertanian Kelompok Tani Nunuh Naek Desa Napan, memiliki sumber daya alam melimpah yang belum dikelola secara optimal, sehingga sering terbuang percuma dan menjadi limbah pertanian akibat keterbatasan wawasan dan ketrampilan petani. Kondisi agroekosistem lahan kering dengan solum dangkal, dan tingginya frekuensi serangan hama sering menyebabkan gagal panen. Sementara itu, ketergantungan petani pada penggunaan pupuk dan pestisida kimia meningkatkan biaya produksi, dan merusak lingkungan. Permasalahan ini menjadi dasar pelaksanaan kegiatan pengabdian yang bertujuan untuk meningkatkan pengetahuan dan ketrampilan petani mengolah limbah pertanian menjadi pupuk organik dan eco-enzyme. Metode: PkM ini menerapkan metode penyuluhan (edukasi) dan demonstrasi langsung (learning by doing) dengan pendekatan particypatory action research. Peningkatan pengetahuan dan ketrampilan mitra diukur berdasarkan instrumen kueioner. Hasil: PkM membuktikan adanya peningkatan wawasan dan ketrampilan petani mitra, serta perubahan perilaku dalam mengolah limbah pertanian menjadi pupuk organik dan eco-enzyme berkualitas, yang siap mewujudkan kemadirian pupuk dan biopestisida. Kesimpulan: Pengaplikasian pupuk organik dan eco-enzyme pada tanaman hortikultura telah berhasil meningkatkan produktivitas serta efektif menekan biaya produksi kelompok mitra. Selain itu, kondisi fisik, biologi dan kimia tanah juga mengalami perbaikan, menjadikan menjadi subur.

Abstract

Classical quantile regression is global generalized parameter estimation results, spatial heterogeneity conditions cannot be captured by this model. The use of local models with spatial attribute can accommodate the characteristics between observation locations. The local quantile regression model is called the Geographically Weighted Quantile Regression (GWQR) model. Further testing of the effectiveness of this model is required by utilizing simulation data. This study uses simulated data generated with sample sizes uniformly distributed with intervals (0,1) contaminated with 5%, 10%, 15% outliers, with predictor variables (x=4) (β1,β2,β3,β4), and quantile sizes of 0.05, 0.25, 0.50, 0.75 and 0.95. Model effectiveness is measured based on Root Mean Square Error (RMSE). From the test, GWQR model can overcome the problem of outliers in simulated data up to the amount of outlier contamination of 15%, and spatial heterogeneity. The RMSE value is getting closer to 0 as the sample size and outliers increase. The test results explain that the 0.95 quantile produces the best parameter estimates compared to other quantiles.
