Abstract

Bengkulu Province ranks second in the category of the highest percentage of poor people in the Sumatra region, at 14.62% in March 2022, and sixth in Indonesia, which is undoubtedly one of the fundamental problems that requires mutual attention. The phenomenon of high poverty in Bengkulu Province is inseparable from the lives of people whose main livelihood is in the agricultural sector, especially tenant farmers. Therefore, in this study, the Copula and Gaussian Copula Marginal Regression (GCMR) methods are applied to determine how the agricultural sector affects poverty in Bengkulu Province using secondary data obtained from the Bengkulu Provincial Statistics Agency (Susenas 2022). The results show that the Copula model can identify various types of dependency between the number of poor households in each district/city in Bengkulu Province in 2022 and each of the variables, namely the Number of Agricultural Business Households , the Growth Rate of the Agricultural Sector , the Human Development Index , and the Open Unemployment Rate ( ) by considering the different characteristics of dependency such as top-tail, bottom-tail, or negative dependency. Meanwhile, the GCMR model can provide the direction of influence of the independent variables on the dependent variable Y, where it can be seen that the variables , , and have a negative influence on the variable , whie the variable has a positive impact on the variable . Therefore, in general, it can be concluded that either positive or negative dependencies identified by the Copula model can influence the resulting GCMR model by providing more profound complexity regarding the relationship between the variables analyzed.

Abstract

Nubamado Village, Lembata Regency has the potential for kepok bananas (Musa acuminata balbisiana Colla) which are still processed and utilized traditionally so this potential has little economic value. This training aims to provide knowledge and skills to residents to process this potential into functional food. The activity method is training. Activity results: partners are enthusiastic about participating in the training.  Ingredients: 5 kg of fresh bananas, peeled, sliced, dried in the sun, then blended until smooth and filtered. Obtained 2.3 kg of flour. Young Moringa leaves are also dried and blended until they become a fine white powder. Add 200 grams of banana flour, one chicken egg, 50 grams of margarine, 10 grams of sugar and 5 grams of Moringa leaf powder. The dough is formed into semi-circular cookies with a diameter of 5cm and baked in the oven until dry. There were 62 cookies obtained. The training participants tasted the cookies produced and expressed their liking and joy because they had gained knowledge, skills and experience in making banana cookies.

Abstract

Earthquakes are natural events whose time and place cannot be predicted. Ambon is the largest city in the Maluku Islands region and is the center of development and the capital of Maluku Province. This research will group earthquake events, analyze the characteristics of earthquake events, create earthquake zones and map them using CLARA cluster analysis, and create modeling that will look at the risk of earthquake events in a location based on distance to faults and subduction zones using the Inhomogeneous Neyman-Scott Cox Process. The data used is data on earthquake events in the Ambon region obtained from the United States Geological Survey (USGS) catalog from January 1926 to December 2022, with a depth of ≤360.1 Km and a magnitude of ≥4 Mw. Grouping earthquake events in the Ambon area using CLARA cluster analysis obtained 2 groups of earthquake clusters with an optimal silhouette score of 0.7430. The model obtained in this earthquake research is not good because it is based on the K-function value plot of the original data which is far from the modeling K-function value plot.

Abstract

Penelitian ini menyoroti rendahnya pemahaman dalam pengolahan data di kelas 12 jurusan PPLG SMKN 1 Kota Bengkulu, yang menjadi hambatan dalam pengembangan perangkat lunak dan gim. Dengan tujuan meningkatkan keseimbangan dalam pengembangan tersebut, penelitian dilakukan melalui pengenalan statistika menggunakan program R. Metode Penelitian Tindakan Kelas diterapkan dalam satu hari pada 12 September 2023, dengan pengumpulan data menggunakan kuisioner dan tes. Hasil menunjukkan bahwa 97,1% siswa menganggap program R mudah dimengerti, 100% merasa mudah digunakan untuk perhitungan statistik, 94,3% menyatakan output mudah dipahami, dan 100% siswa mampu memahami materi. Analisis data menggunakan teknik kuantitatif, dengan uji t berpasangan menunjukkan peningkatan yang signifikan (). Dengan demikian, Upaya Pemanfaatan Teknologi (Program R) dalam Pengenalan Statistika di SMK Negeri 1 Kota Bengkulu memberikan manfaat dan peningkatan pengetahuan pada taraf signifikansi 0,05.
