Abstract

Floods are among the most common and dangerous natural disasters worldwide, leading to loss of life and economic instability. In Indonesia, floods have been the most frequently occurring natural disaster since 2009. The high frequency underscores the urgency of predicting the number of natural disaster events to assist the government and the public in taking appropriate mitigation measures, as well as contributing to the achievement of Sustainable Development Goal 15 regarding Terrestrial Ecosystems. The method used to predict the monthly occurrence of floods in Indonesia is Long Short Term Memory (LSTM). LSTM was chosen for its ability to process sequential data over a long period of time. Upon analysis, highly accurate forecasting results were obtained, with a Mean Absolute Percentage Error (MAPE) of 8.04%, a Root Mean Square Error (RMSE) of 5.991. The model is also proficient at estimating training data, with an value of 95.71%.

Abstract

The well-being of society, involving the fulfilment of basic needs and opportunities for education and employment, can be measured through the happiness index. This research aims to assist the Indonesian government in achieving Sustainable Development Goal 3 related to Health and Well-being. It is hoped that by comprehending these factors, the government can improve the health and well-being of the Indonesian population. The happiness index varies across different geographical regions due to factors such as culture, social dynamics, and the environment, which can have different impacts from one region to another. Given the randomness in data patterns stemming from the diverse provinces in Indonesia, this study employs the Mixed Geographically Weighted Regression (MGWR) method. Results reveal that the MGWR model, utilizing a fixed Gaussian kernel weight, yields the lowest Akaike’s Information Criterion Corrected and the highest at 87.2%, underscoring its precision in modeling the happiness index in Indonesia.

Abstract

Kabupaten Sidoarjo merupakan kawasan industri dengan potensi besar pada sektor UMKM, termasuk Desa Tambaksawah yang telah mengembangkan berbagai produk makanan dan kerajinan tangan. Namun, pelaku UMKM masih menghadapi kendala dalam perizinan usaha, pemasaran terbatas, serta kurangnya pemahaman mengenai legalitas usaha. Kegiatan Pengabdian Masyarakat yang dilaksanakan pada Maret – September 2023 bertujuan memperluas jangkauan pemasaran melalui digital marketing dan meningkatkan pemahaman terkait legalitas usaha. Kegiatan meliputi tahap persiapan, pelatihan, pendampingan, monitoring, dan evaluasi. Sebanyak 9 UMKM berhasil membuat akun TikTok dan 30 video promosi diproduksi sebagai strategi branding digital. Selain itu, UMKM mulai beralih dari pemasaran berbasis WhatsApp menuju penggunaan media sosial yang lebih luas, sehingga meningkatkan visibilitas produk dan peluang perluasan pasar. Secara umum, kegiatan berjalan baik, ditunjukkan oleh hasil kuesioner yang mayoritas menyatakan pelaksanaan sangat baik. Meski demikian, penerapan informasi perizinan masih perlu ditingkatkan, karena baru sekitar 50% pelaku UMKM yang telah mendaftarkan usahanya.
