Abstract This study discusses the forecasting of 3 kg LPG gas sales at the Carica House Grocery Store. This shop as one of the LPG gas agents in the Kaliwiro area who sells 3 kg LPG Gas either retail or reseller, the number of requests for LPG gas in stores is very high , thus causing the sale of LPG gas in the shop is always uncontrolled between incoming goods and outgoing goods. Therefore, it is necessary to forecast sales. Sales forecasting has the meaning as an activity to predict product sales by using previous data as a reference in making decisions. The development of this forecasting model aims to get better forecasting results, especially regarding the accuracy of forecasting results. The Fuzzy Time Series method is used to predict the demand for 3 kg gas cylinders for the next month based on the pattern from the previous data. In data forecasting using this method, there are two forecasting techniques, namely qualitative analysis and quantitative analysis. Then for the calculation of the error value from the forecasting results, this study using MAPE produces an error value of 0,3% because it states the percentage of error results more accurately.

Padi merupakan salah satu sumber makanan pokok yang dikonsumsi masyarakat Indonesia. Namun kebutuhan beras masyarakat yang semakin meningkat tidak diimbangi dengan pertumbuhan area pertanian. Luas panen kota/kabupaten di provinsi Jawa Tengah di tahun 2020 mengalami penurunan dibandingkan tahun sebelumnya. Selain itu produksi padi juga mengalami penurunan. Oleh karena itu provinsi Jawa Tengah perlu mengelompokkan kota/kabupaten penghasil padi untuk mengetahui daerah yang memiliki potensi dalam memproduksi padi. Metode yang dapat digunakan dalam mengelompokkan kota/kabupaten penghasil padi adalah clustering. Clustering dapat mengelompokkan data tersebut berdasarkan kesamaan jenis data ke dalam cluster. Pada penelitian ini dilakukan pengelompokkan kota/kabupaten penghasil padi di Jawa Tengah dengan metode clustering. Clustering yang digunakan adalah dengan menggunakan algoritma K-Means. Hasil yang didapatkan dari metode ini yaitu 3 cluster antara lain C0 menggambarkan daerah yang hasil produktivitas padinya sedang terdiri dari 12 daerah. C1 menggambarkan daerah yang hasil produktivitas padinya rendah terdiri dari 18 daerah. Serta C2 menggambarkan daerah yang hasil produktivitas padinya tinggi terdiri dari 12 daerah.

Word embedding vectorization is more efficient than Bag-of-Word in word vector size. Word embedding also overcomes the loss of information related to sentence context, word order, and semantic relationships between words in sentences. Several kinds of Word Embedding are often considered for sentiment analysis, such as Word2Vec and FastText. Fast Text works on N-Gram, while Word2Vec is based on the word. This research aims to compare the accuracy of the sentiment analysis model using Word2Vec and FastText. Both models are tested in the sentiment analysis of Indonesian hotel reviews using the dataset from TripAdvisor.Word2Vec and FastText use the Skip-gram model. Both methods use the same parameters: number of features, minimum word count, number of parallel threads, and the context window size. Those vectorizers are combined by ensemble learning: Random Forest, Extra Tree, and AdaBoost. The Decision Tree is used as a baseline for measuring the performance of both models. The results showed that both FastText and Word2Vec well-to-do increase accuracy on Random Forest and Extra Tree. FastText reached higher accuracy than Word2Vec when using Extra Tree and Random Forest as classifiers. FastText leverage accuracy 8% (baseline: Decision Tree 85%), it is proofed by the accuracy of 93%, with 100 estimators.

Paguyuban Turah Runtah merupakan sebuah komunitas masyarakat yang bergerak di bidang sosial terutama dalam pembenahan lingkungan. Salah satu aktivitas utama dari paguyuban ini adalah melakukan sosialisasi kepada masyarakat agar tidak membuang sampah sembarangan serta menjaga lingkungan agar tetap bersih. Selama menjalankan aktivitas sosialisasi tersebut, Turah Runtah menggunakan media poster yang ditempel di tempat-tempat yang rawan dijadikan tempat untuk membuang sampah secara sembarangan. Poster-poster tersebut didesain dan dihasilkan oleh desainer grafis dari percetakan yang secara otomatis membutuhkan biaya yang cukup besar.
