Abstract

In the process of admitting new students, each school has a different strategy to increase the number of applicants and the number of students accepted. The publication strategy is structured to achieve the expected goals or to get the number of students according to the quota. The publication strategy will work well if the school has predictive data on the number of students that will come. Therefore, researchers do research with the purpose to predict the number of new students at SMA Ya Bakii 1 Kesugihan using the Trend Linear model with the Least Square to the number of new students from 2002/2003 to 2022/2023. The results of the analysis show that the Least Square Method prediction model in the form of y =49.424+4.463x gives accurate or good results with a MAPE value of 11.996%. While the prediction results for the next five years, namely 2023/2024, 2024/2025, 2025/2026, 2027/2028, and 2029/2030 are 148 students, 152 students, 157 students, 161 students, and 165 students.

Abstract

This research aims to predict daily maximum and minimum air temperatures in Cilacap Regency using ARIMA and Exponential Smoothing. Data was obtained from recordings carried out by BMKG Cilacap using maximum and minimum thermometers taken from January 1, 2016, to December 31, 2021. The results show that the best forecasting model uses the ARIMA (2,1,2) model for maximum temperature and the ARIMA (1,1,1) model for minimum temperature, with the MAPE value of 2.09% for the maximum temperature and 2.44% for the minimum temperature, while the RMSE value obtained is 0.9177 for the maximum temperature and 0.8001 for the minimum temperature. Based on the ARIMA model, Cilacap's daily maximum temperature in 2022 was predicted to be around 30.6ᵒC, with a 95% confidence interval between 28ᵒC - 35ᵒC, while the minimum temperature was predicted to be around 25.1ᵒC, with a 95% confidence interval between 23ᵒC - 28ᵒC.

Abstract

Distribution of election logistics requires a large budget. Therefore, distribution planning is needed to streamline the budget. One form of planning is in the form of planning the shortest distribution route. This research aims to determine the shortest route for distribution of election logistics in Cilacap Regency using the Branch and Bound Algorithm. Determining the distance between sub-districts in Cilacap Regency using the help of GoogleMaps. Based on the results of this research, the shortest route for distribution of election logistics in Cilacap Regency is 149.1 km for the first route and 335 km for the second route.

Abstract

Abstract. Statistics is a field of science that can be used as a theory to assist in making research decisions, especially quantitative research. Appropriate statistical tests are needed to analyze research data based on the formulated hypotheses. For this reason, a good ability in analyzing data is needed. The process of data analysis in quantitative research can be assisted using the SPSS statistical program. Most of the students in Cilacap who have an interest in quantitative research still need additional knowledge about the statistical tests used such as the T-test, Analysis of Variance and Regression, and Linear Correlation. In addition, many students have difficulty analyzing data using the SPSS program. Misunderstanding in reading SPSS output results caused many errors to occur. On the other hand, many students do not understand the prerequisites for hypothesis analysis and do not know the procedures or steps for data processing using SPSS. For this reason, a deeper understanding and training are needed to process data using SPSS. The SPSS training was conducted using lectures, question and answer methods, and practicals. In the process, they were very active in asking questions and actively following all the material given by the resource persons. The instrument is given as evaluation material for further service. it was obtained that the achievement of all aspects was classified as good with details on the suitability aspect of statistical tests with problems of 83%, the achievement of variable research aspects of 81%, the achievement of data processing aspects using SPSS of 86%, the achievement of SPSS output interpretation of 89%. Abstrak. Statistika merupakan bidang ilmu yang dapat menjadi teori untuk membantu dalam pengambilan keputusan suatu penelitian khususnya penelitian kuantitatif. Dalam menganalisis data penelitian dibutuhkan uji statistik yang sesuai berdasarkan hipotesis yang dirumuskan. Untuk itu, diperlukan kemampuan yang baik dalam menganalisis data. Proses analisis data dalam penelitian kuantitatif dapat dibantu menggunakan program statistika SPSS. Mahasiswa di Cilacap yang memiliki minat dalam penelitian kuantitatif sebagian besar masih membutuhkan tambahan pengetahuan mengenai uji statistik yang digunakan seperti uji T, Analisis Variansi serta Regresi dan Korelasi linear. Selain itu, banyak mahasiswa yang kesulitan dalam analisis data menggunakan program SPSS. Ketidakpahaman dalam membaca hasil output SPSS menyebabkan tidak sedikit kekeliruan terjadi. Di sisi lain, banyak mahasiswa yang tidak paham akan prasyarat analisis hipotesis, serta ketidaktahuan prosedur atau langkah pengolahan data menggunakan SPSS. Untuk itu, tujuan kegiatan ini dilakukan ialah untuk memberikan tambahan pengetahuan, pemahaman dan keterampilan dalam mengolah data menggunakan SPSS. Pelatihan SPSS ini dilakukan dengan metode ceramah, tanya jawab serta praktikkum. Dalam prosesnya mereka sangat aktif bertanya dan aktif mengikuti semua materi yang diberikan oleh narasumber. Instrumen diberikan sebagai bahan evaluasi untuk pengabdian selanjutnya. Diperoleh bahwa ketercapaian seluruh aspek tergolong kategori baik dengan rincian pada aspek kesuaian uji statistik dengan permasalahan penelitian sebesar 83%, ketercapaian aspek identifikasi variabel penelitian sebesar 81%, ketercapaian aspek pengolahan data menggunakan SPSS sebesar 86%, serta ketercapaian intepertasi output SPSS sebesar 89%.

Abstract

Pembangunan ekonomi berkelanjutan dan pemberdayaan masyarakat merupakan aspek penting dalam pengembangan desa. Salah satu cara untuk mencapai tujuan tersebut adalah dengan memanfaatkan sumber daya lokal secara optimal. Penelitian ini mengkaji pelatihan dan pemanfaatan limbah batok kelapa menjadi briket di Desa Mangunweni, Kebumen, sebagai alternatif energi terbarukan dan peluang usaha. Metode pelaksanaan meliputi survei lokasi, analisis kebutuhan, sosialisasi, praktik pembuatan briket, dan evaluasi akhir. Hasil kegiatan menunjukkan bahwa masyarakat belum mengenal briket dan pemanfaatan limbah batok kelapa sebelumnya. Pelatihan ini berhasil memperkenalkan teknik pembuatan briket, memungkinkan masyarakat untuk membuat briket sendiri, dan membuka peluang usaha baru. Selain itu, kegiatan ini mengurangi limbah batok kelapa serta meningkatkan pemahaman masyarakat tentang penggunaan sumber daya lokal dan pengembangan ekonomi kreatif. Kesimpulannya, pelatihan ini tidak hanya memberikan solusi alternatif untuk kebutuhan energi, tetapi juga mendorong kewirausahaan dan menjaga kelestarian lingkungan di Desa Mangunweni.

Abstract

This study discusses about optimal control for spread of Covid-19 disease with the assumptionthat there is a subpopulation of individuals infected with the new variant of Covid-19. Transmission canoccur between individuals in susceptible subpopulations and individuals in subpopulations infected withCovid-19. SIVRS model is used by assumes that there is control variable in the form of the vaccinationstrategy given to susceptible individuals. This study aims to minimize the number of individuals in thesubpopulation infected and infected with the new variant. An analysis of the optimal control solution wascarried out using the Hamiltonian function and then solving it using the Sweep Forward and Back methodin Matlab. The results show that the vaccination strategy implemented can minimize the number ofindividuals in the subpopulation infected and infected with the new variant.
