Abstract

Dalam menanggulangi pandemi COVID-19, upaya vaksinasi dilakukan tidak hanya menjadi satu-satunya upaya untuk melindungi masyarakat dari penularan COVID-19. Selama belum mencapai kekebalan kelompok (herd immunity), maka pencegahan yang efektif saat ini adalah pola hidup bersih sehat. Adapun tujuan dari pengabdian masyarakat yang dilaksanakan di Desa Kota Padang Kecamatan Manna Kabupaten Bengkulu Selatan adalah agar masyarakat setempat dapat mengetahui pentingnya vaksinasi dan mengedukasi diri bagaimana cara untuk melaksanakan pola hidup bersih sehat di masa pandemi COVID-19. Hasil yang diperoleh dari kegiatan ini yaitu dengan adanya kegiatan ini telah mengedukasi dan membantu masyarakat untuk memahami apa itu vaksinasi dan pentingnya vaksinasi, serta bagaimana menerapkan perilaku hidup bersih sehat di masa pandemic Covid-19 di lingkungan masyarakat Desa Kota Padang Kecamatan Manna Kabupaten Bengkulu Selatan. Dilihat dari evaluasi, masyarakat Desa Kota Padang 94% telah melaksanakan vaksinasi Covid-19, dan 50% telah mengetahui bagaimana perilaku hidup bersih sehat, serta 94% juga yang telah menerapkan protocol kesehatan di kehidupan sehari-hari.

Abstract

An earthquake is a natural disaster that occurs suddenly resulting in numerous casualties, such as loss of life and property. Bengkulu Province is among the provinces affected by severe earthquakes. Studies on probability models for the frequency of earthquake events in Bengkulu Province are still scarce, as outlined in the 2017 book “Map of Sources and Hazards of Indonesian Earthquakes.” This research uses Poisson mixture models to build a probability model for the frequency of earthquake events in the Enggano segment, located in the coastal area of Bengkulu Province.   ..   The phases of model building are the model diagnosis phase, testing the dispersion state relative to the Poisson distribution, testing the dependence of research data on time variables using the Ljung-Box test, and testing the criteria for selecting the best model using the Bayesian Tests Measures of Information Criterion (BIC) and Akaike Information Criterion (AIC). Annual earthquake frequency data from January 1, 1971, to December 31, 2022, were retrieved from the USGS catalog of data on the frequency of major earthquakes with a magnitude of Mw ≥ 4.40, which occurred a total of 633 times. After completing the model building phase, the AIC and BIC values for each model were determined by determining the number of unobserved groups. Both Poisson mixture models and Poisson hidden Markov models produced the same number of unobserved groups of 3 groups with AIC=302.91 and BIC=324.38.

Abstract

The waste problem is one of the serious problems faced by every city in Indonesia, including Bengkulu City. To overcome the problem of waste production which continues to increase every day, the government's role is needed in efforts to transport waste with various facilities and support from the surrounding community. One effort to solve the problem of waste piling up in Temporary Disposal Sites (TPS) is to schedule effective transportation to Final Disposal Sites (TPA). To do the scheduling, one possible approach is a mathematical approach. The purpose of this research is to build a Vehicle Routing Problem (VRP) model using Ant Colony Optimization (ACO), and determine the solution of this model to determine the optimal solution to the problem of transporting waste from all TPS to TPA. This research involved 29 TPS in Bengkulu City. This model is solved using Python 2.7 programming language and PuLP modeller and CPLEX Solver. With 2000 iterations, solutions were found in a relatively short time, which is less than 10 minutes. There are 6 garbage transportation routes in Bengkulu City which are considered as a VRP problem by using ACO which can transport garbage and considering the capacity of garbage trucks. From this route, a total distance of 128 km is obtained.
