Abstract

The purpose of this study is to obtain a forecasting model for the number of train passengers using time series regression integrated with variations in the Islamic calendar and the effects of COVID 19. This study uses the number of train passengers in Jabodetabek, Java (Non-Jabodetabek), and Sumatra from January 2006 to December 2022 as the data source. Time series regression with variations of the Islamic calendar and the effects of COVID 19 for Jabodetabek, Java (non-Jabodetabek), and Sumatra has an RMSE value for each category of 7657,821; 2453.827 and 275.901. In general, the number of train passengers for all categories (Jabodetabek, Java, Sumatra) has a seasonality. In Jabodetabek and Sumatra, Eid al-Fitr has a big impact on the number of train passengers. Meanwhile, one month before Eid al-Fitr has a big impact on the number of train passengers in Java (Non Jabodetabek). In addition, the impact of COVID 19 significantly affected the number of train passengers for all categories.

Abstract

Background: Stock price forecasting assists investors to anticipate risks and opportunities in making prudent investments and maximizing returns. Objective: This study aims to identify the most accurate model for stock forecasting. Methods: This paper utilized the daily closing stock price of Unilever Indonesia, Tbk (UNVR) from January 1, 2018 to July 31, 202.  Double Seasonal Autoregressive Integrated Moving Average (DSARIMA), was utilized in this study. Mean Absolute Scaled Error (MASE) and Median Absolute Percentage Error (MdAPE) are used to compare forecasting accuracy. Results: Following conducting each model, we assessed that the best models are DSARIMAX (0,1,[4]) ([3],1,1)5(1,1,0)253, regarding MASE and MdAPE corresponding to approximately 1.423 and 0.111. The scope of this study has limitations to a test set for one-month forecast periods. Conclusion: As stock prices rise, investors require precise forecasts. Models of forecasting must perform well. This analysis shows how the DSARIMA generate forecasts stock prices more accurately. This investigation evaluated the closing stock price of UNVR. Both MASE and MdAPE assess prediction. After analyzing each model, DSARIMAX (0,1,[4])([3],1,1)5(1,1,0)253 has the lowest MASE and MdAPE values, 1.423 and 0.111, respectively. The procedure lasted one month. Research may combine forecasts and improve their accuracy.

Abstract

Kalkulus 2 adalah mata kuliah wajib bagi seluruh mahasiswa semester 2 di Institut Teknologi Kalimantan. Matakuliah ini memberikan konsep dasar berfikir matematis pada mahasiswa dalam menyelesaikan masalah-masalah real serta menjadi dasar kemampuan untuk mengikuti mata kuliah tingkat lanjut yang menerapkan konsep kalkulus di dalamnya. Metode assesment pada mata kuliah ini meliputi ujian tertulis berupa kuis, post test, ujian tengah dan akhir semester, tugas mandiri/kelompok, dan keaktifan. Sedangkan komposisi nilai evaluasi berdasarkan nilai Sub CMPK 1, Sub CMPK 2, Sub CMPK 3, Sub CMPK 4, Sub CMPK 5, Sub CMPK 6 dan Sub CMPK 7. Hasil kuesioner kinerja dosen adalah evaluasi yang selalu dilakukan oleh mahasiswa setelah proses belajar mengajar selama satu semester selesai. Hasil kuesioner kinerja dosen yang baik haruslah linier dengan hasil evaluasi mahasiswa yang baik pula. Oleh karena itu dilakukan analisis terkait hubungan antara kuesioner kinerja dosen sebagai variabel respon dengan nilai evaluasi sebagai variabel prediktor dengan analisis statistika deskriptif, uji ANOVA dan uji parsial t. Hasil analisis ini menunjukkan bahwa tidak ada variabel prediktor yang berpengaruh signifikan terhadap variabel respon. Hal ini juga dibuktikan dengan nilai R2 Adjusted sebesar 0,14%. Hal tersebut memiliki arti bahwa kemampuan variabel prediktor dalam penelitian ini mempengaruhi variabel respon sebesar 0,14%, sedangkan sisanya sebesar 99,86% dijelaskan oleh variabel lain selain variabel prediktor dalam penelitian ini. Berdasarkan komentar mahasiswa pada kuesioner kinerja dosen, diketahui bahwa mahasiswa sangat mengapresiasi kualitas mengajar dosen meskipun mahasiswa tidak mampu menyerap optimal apa yang diajarkan dosen tersebut karena mata kuliah Kalkulus 2 adalah mata kuliah yang berat.

Abstrak: Pembangunan desa memiliki tujuan untuk meningkatkan kesejahteraan masyarakat dan kualitas hidup manusia. Untuk mewujudkan Indonesia yang maju, desa-desa diharapkan memiliki kemampuan dalam memanfaatkan teknologi dan informasi. Kehadiran teknologi dan informasi, tidak hanya memberi kemudahan tetapi juga memunculkan aksi kejahatan. Kondisi ini akan menciptakan potensi risiko yang signifikan terkait ancaman kejahatan cyber. Selain itu, Adanya data yang akurat dan lengkap dalam mengelola suatu wilayah juga merupakan hal yang tidak dapat diabaikan. Dengan pendataan yang baik, suatu organisasi dapat membuat keputusan yang lebih tepat dan efektif. Untuk mengatasi permasalahan tersebut, dilakukan serangkaian kegiatan pengabdian masyarakat yang mencakup sosialisasi mengenai keamanan siber serta perancangan website untuk mendukung pengelolaan data desa. Kegiatan ini melibatkan kurang lebih 60 penduduk yang terdiri dari perangkat desa dan masyarakat umum. Selanjutnya, evaluasi dilakukan menggunakan kuisioner dan wawancara untuk mengukur efektivitas program. Hasil analisis evaluasi kegiatan-kegiatan yang telah dilakukan, diketahui bahwa 56% warga berpendapat bahwa kegiatan pengabdian yang telah dilakukan sudah sangat baik.Abstract: Village development aims to improve community welfare and the quality of human life. To realize an advanced Indonesia, villages are expected to have the ability to utilize technology and information. The presence of technology and information not only provides convenience but also gives rise to criminal acts. This condition will create significant potential risks related to the threat of cybercrime. In addition, the existence of accurate and complete data in managing an area is also something that cannot be ignored. With good data collection, an organization can make more precise and effective decisions. To overcome this problem, a series of community service activities were carried out which included socialization regarding cyber security and website design to support village data management. This activity involved approximately 60 residents consisting of village officials and the general public. Furthermore, an evaluation was carried out using questionnaires and interviews to measure the effectiveness of the program. The results of the evaluation analysis of the activities that had been carried out, it was found that 56% of residents thought that the community service activities that had been carried out were very good.

Abstract

The purpose of this community service is to improve the efficiency and transparency of waste management through the development of a web-based information system called SekarCycle at the Sekar Waste Bank in RT 18 Balikpapan. The background of this activity is the process of recording waste transactions that have been done manually, which tends to be inefficient, prone to errors, and difficult to track. Starting with field observations and determining partner needs, the activity continued with the creation of a digital system, user instructions, and the development of social media accounts as a means of education. The results of the activity showed the ability of the SekarCycle system to accelerate recording, improve data accuracy, and make transaction reports easier. Educational activities and ecoenzyme workshops also encouraged residents to use household waste management methods. This program shows that sustainable waste management at the community level can be achieved through the integration of appropriate technology and participatory methods.
