The use of data processing skills is something that is very important in various fields. The data processing process can use various applications, one of which is the number/data processing application which is commonly known as the Ms. Excel application.

Abstract

The Indonesian capital market is one of the investment destinations for investors from developed countries. The development of Indonesia's economic conditions is considered good for investors in investing their funds. Financial sector shares are one of the sectors that has experienced development throughout this year. One of the seven stocks showing good growth is PT Lippo General Insurance Tbk (LPGI). The important thing that is the main concern of investors is the level of yield or return from a stock. Based on this, stock return forecasting analysis can be important information for investors. This research uses the GARCH method to forecast LPGI stock returns. The analysis results show that the best model for LPGI stock returns is ARIMA (2,0,0) GARCH (1,1) with a very small return value and a negative sign. Thus, these results provide information that the forecasting period is not the right time for investors to buy LPGI shares. However, investors who have bought LPGI shares and made a profit are advised to sell LPGI shares before the forecast period. The empirical evidence from this study demonstrates that the GARCH model can effectively capture the volatility pattern of LPGI stock returns in n financial market. This finding supports the application of GARCH in modeling return fluctuations in emerging markets.

Abstract

Hingga saat ini terdapat sekitar 15 Usaha Mikro, Kecil, dan Menengah yang ada di Desa Badran Sari. Kegiatan usaha yang dilakukan oleh UMKM tidak terlepas dari transaksi keuangan baik transaksi masuk maupun keluar. Apabila transaksi tersebut diolah dengan baik maka dapat menghasilkan laporan keuangan yang tepat untuk berbagai periode waktu. Dengan adanya laporan keuangan yang tepat, maka bisa didapatkan informasi yang tepat mengenai kondisi keuangan dari suatu usaha sehingga bisa membuat keputusan yang tepat untuk masa yang akan datang. Dengan rendahnya kemampuan masyarakat desa dalam mengolah informasi sehingga menjadikan para pelaku UMKM tidak dapat memanfaat informasi keuangan yang mereka miliki sebagai dasar dalam pengambilan keputusan dan pengembangan usahanya. Oleh karena itu perlu diadakannnya suatu pelatihan terkait pembuatan laporan keuangan untuk meningkatkan kemampuan masyarakat Desa Badran Sari yang memiliki UMKM sehingga tercapainya masyarakat informasi dan berbasi pengetahuan. Hal ini diharapkan dapat meningkatkan ukuran usaha UMKM dan meningkatkan kegiatan perekonomian di Desa Badran Sari, Kecamatan Punggur, Kabupaten Lampung Tengah. Setelah dilaksanakannya pelatihan mengenai penyusunan laporan keuangan, jumlah peserta yang memiliki tingkat pemahaman rendah mengalami penurunan dari semula 68,18% menjadi 36,36% dan jumlah responden dengan tingkat pemahaman sedang mengalami peningkatan lebih dari dua kali lipat dari semula 27,27% menjadi 59,09%

This Community Service (PkM) program aims to enhance students’ competencies in data analysis and statistical dashboard management through the utilization of the Looker Studio application. The training was conducted at SMKS Nurul Huda Pringsewu, involving students as participants. The training methods included lectures, demonstrations, and hands-on practice in processing data and presenting it in the form of interactive dashboards. The results of the program showed that students were able to understand the basic concepts of data exploration, the purpose of data visualization, and the use of key features in Looker Studio. In addition, students’ skills in selecting appropriate chart types according to analytical needs improved significantly. Based on the satisfaction survey, most participants rated the activity as very satisfactory (63%) and satisfactory (16%), although a small proportion expressed dissatisfaction (16%) or were not satisfied (5%). Overall, this PkM activity successfully contributed to improving students’ data literacy and digital skills, which are expected to support them in facing both academic challenges and the demands of a data-driven workforce
