The problem proposed in this research is about the amount rainy day per a month at Balikpapan city and discretetime markov chain. The purpose is finding the  probability of rainy day with the frequency rate of rainy at the next month if given the frequency rate of rainy at the prior month. The applied method in this research is classifying the amount of rainy day be three frequency levels, those are, high, medium, and low. If a month, the amount of rainy day is less than 11 then the frequency rate for the month is classified low, if a month, the amount of rainy day between 10 and 20, then it is classified medium and if it is more than 20, then it is classified high. The result is discrete-time markov chain represented with the transition probability matrix, and the transition diagram.

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.

This study aims to classify money market fund products listed and supervised by the Financial Services Authority (OJK) with minimal classification error. Mahalanobis distance and Manhattan distance were employed to classify these products. Data was sourced from the Indo Premier Online Technology (IPOT) application. Variables utilized in this research include percentage return, Sharpe ratio, unit growth, and Asset Under Management (AUM) . Additionally, Principal Component Analysis (PCA) was employed to reduce data dimensionality by linearly combining correlated original variables into new variables (principal components). PCA was used to visualize data with more than three dimensions. Based on the principal component analysis, the first two principal components captured 74.43% of the original data information, while the first three principal components captured 98.94%. Classification results using three principal components and standardized data showed the same error rates: 13.33% for Mahalanobis distance and 6.67% for Manhattan distance. For the two principal components, both Mahalanobis and Manhattan distances resulted in an error rate of 13.33%. Therefore, Manhattan distance is the most effective method for classification. Forecasting results indicate that mutual fund A is a good investment choice, while mutual fund B is a poor one. Keywords: Mahalanobis distance; Manhattan distance; Principal Component Analysis

Peningkatan usia harapan hidup di Indonesia berdampak pada bertambahnya jumlah penduduk lanjut usia (lansia), sehingga menuntut strategi pembangunan yang inklusif agar kelompok ini tetap dapat berkontribusi secara produktif. Salah satu pendekatan yang relevan adalah pemberdayaan ekonomi berbasis komunitas, khususnya melalui sektor usaha mikro, kecil, dan menengah (UMKM). Di tengah upaya transformasi regulasi UMKM, pemahaman terhadap bentuk badan usaha menjadi semakin penting. Namun demikian, rendahnya literasi hukum di kalangan pelaku UMKM lansia masih menjadi kendala utama dalam proses legalisasi usaha yang berkelanjutan. Untuk menjawab tantangan tersebut, kegiatan Pengabdian Kepada Masyarakat (PKM) ini diselenggarakan di Kampung Inspisari, Kota Bandung, dengan tujuan meningkatkan kapasitas dan literasi hukum para pelaku UMKM lansia. Metode pelaksanaan meliputi ceramah interaktif, simulasi peran, dan evaluasi partisipatif untuk memastikan pemahaman menyeluruh peserta. Hasil kegiatan menunjukkan metode Pendidikan hukum klinik efektif dalam peningkatan signifikan dalam pemahaman peserta mengenai karakteristik hukum dari masing-masing bentuk badan usaha serta urgensi legalitas dalam mendukung akses pembiayaan dan perlindungan hukum. Antusiasme peserta mencerminkan tingginya kebutuhan terhadap edukasi legalitas yang sesuai dengan konteks komunitas.
