Sales forecasting is a critical aspect of the automotive business as it influences marketing strategies, production, and inventory management. This study examines a comparison of Toyota car sales forecasts using the Single Moving Average (SMA) and Single Exponential Smoothing (SES) methods. The primary objective is to evaluate the accuracy of the SES method in predicting Toyota car sales and compare it with actual sales data. Historical sales data serve as the basis for forecasting, with the smoothing parameter α tested to obtain the best results. Forecasting with SMA demonstrates improved accuracy as the number of average periods increases. The 2-period SMA produces forecasts that are more responsive to sales trends, while the 3-period SMA provides more stable predictions without compromising accuracy. Meanwhile, the SES method with α = 0.3 delivers reasonably accurate forecasts. By applying this method, companies can make better decisions regarding Toyota car production and inventory management, ultimately enhancing operational efficiency and customer satisfaction.

Biological assessment is an option in determining river quality, in this case related to river health. The biological assessment indicators used aquatic macroinvertebrates with research sites in the Pusur River which are located in Boyolali and Klaten Regencies, Central Java Province, Indonesia. The use of macroinvetebrata as an indicator because they are very sensitive to changes in water quality, one of which is the EPT group (Ephemeroptera, Plecoptera, and Trichoptera). Sources of river pollution will affect the existence of EPT and there are macroinvertebrates that are adaptive to contamination. This study was conducted at three monitoring stations located in the Pusur River, namely in the upstream, middle and downstream sections where each station had 6 repetitions in sampling followed by calculating the macroinvertebrate assessment index value. The results of the study show that the upstream station has an index value of 2.11 which means it is moderately polluted, the middle station has an index value of 2.40 which means it is moderately polluted and the downstream station has a value of 2.35 which means it is moderately polluted. From these results it is indicated that contamination into the river has started from the upstream area where the contamination originates from the disposal of unprocessed cow manure into river bodies, while in the middle and downstream areas the contamination that occurs is caused by dumping garbage, household waste and the use of pesticides and chemical fertilizers in agricultural ecosystem.

Indonesia is one of the world's largest producers and exporters of coal. Approximately 60 percent of Indonesia's total coal reserves consist of low-quality coal, which is cheaper and has a calorific value of less than 6,100 kcal/gram. In addition to the combustion of low-quality coal waste, there are also Fly Ash and Bottom Ash (FABA). The circular economy has become an important part of the economic model approach, aiming to drive economic growth while minimizing social and environmental damage. Innovations related to coal waste utilization and post-mining reclamation solutions are key aspects of this approach. This study aims to utilize coal waste as a medium for land reclamation using the circular economy concept. Coal Ball Seed (CBS) is an innovation that packages coal into balls containing seeds, growing media, and nutrients, providing the necessary nourishment for seed growth. The best binder found in this study was soil. Coefficient tests showed that the significance level for the composition was below the 0.05 threshold. The test results indicated aSig. value of 0.00, confirming that Coal Ball Seed (CBS) significantly affects the growth of sengon seeds (Falcataria moluccana. The R-square summary test revealed a value of 38.1%, meaning that the growth of Falcataria moluccana seeds is influenced by the composition of CBS itself, while the remaining 61.9% is influenced by other factors. Thus, the optimal CBS composition uses a ratio of Bottom Ash: Clay: Antracol: Liquid Nutrient. The average nutrient content of CBS was measured at N 9 mg/kg, P 2.6 mg/kg, and K 4.3 mg/kg. The utilization of coal waste into CBS plays a role in the circular economy, and its spherical shape makes it highly feasible for distribution via drones in large-scale reclamation efforts

Pengabdian Masyarakat ini dilaksanakan untuk meningkatkan pemahaman petani terhadap teknik pemupukan tanaman kopi yang lebih efektif di Desa Purwosari, Kecamatan Girimulyo, Kabupaten Kulon Progo. Berdasarkan hasil observasi awal diketahui bahwa praktik pemupukan yang dilakukan oleh petani masih belum terukur dan umumnya hanya menggunakan pupuk kandang tanpa proses pengolahan atau fermentasi. Kondisi tersebut menyebabkan pertumbuhan dan produktivitas tanaman kopi belum optimal. Tujuan dari kegiatan ini adalah untuk meningkatkan pemahaman petani tentang pengelolaan pemupukan kopi yang tepat.. Metode kegiatan yang digunakan meliputi observasi lapangan, penyuluhan materi pemupukan kopi, serta diskusi melalui Focus Group Discussion (FGD) bersama petani. Hasil kegiatan menunjukkan terdapat pengembangan pengetahuan awal petani mengenai pentingnya pemupukan yang tepat serta munculnya kesadaran petani terhadap kebutuhan pengelolaan pupuk yang lebih baik. Selain itu, melalui FGD juga diperoleh informasi mengenai permasalahan yang dihadapi petani dalam praktik pemupukan serta kebutuhan pendampingan teknologi pemupukan yang lebih efektif. Kegiatan ini diharapkan menjadi langkah awal dalam penerapan teknologi pemupukan yang lebih tepat melalui kegiatan pelatihan dan demonstrasi plot pada tahap kegiatan berikutnya.
