Abstract

Prambanan Biodiversity Park (TKP), Klaten, Central Java, is an important natural reserve for preservation of local biodiversity and environmental protection by PT.Sarihusada Generasi Mahardhika. This research investigates the park's potential in providing food resources and supporting agricultural practices for nearby communities through plant species identification including ecological relationships between species and plants that contribute to pest control in agricultural systems. The collected data provides an overview of the park's biodiversity and serves as a baseline for further analysis. The research finds several potential benefits of utilizing TKP for food resources and agriculture. The diverse flora of the park offers a variety of edible plants, such as Moringa oleifera and fruit-based species, which can enhance local diets and provide nutritional diversity. Furthermore, traditional plants like mojo hold potential as natural pesticides, contributing to pest control in agricultural fields. The research recommends the development of conservation strategies and policies focused on sustainable practices, community participation, and educational initiatives to maximize the potential benefits. TKP emerges as an invaluable resource capable of supplying essential food provisions and supporting eco-friendly agricultural practices for neighboring communities, thereby emphasizing the criticality of interweaving biodiversity preservation within the framework of local food systems.

Abstract

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.

Abstract

Pemberian unsur nitrogen sangat penting untuk meningkatkan pertumbuhan dan hasil rendemen tanaman tebu. Untuk mengetahui waktu yang tepat agar dapat melakukan pemupukan, maka diperlukan kurva serapan tanaman selama masa pertumbuhan tanaman tersebut. Penelitian ini bertujuan untuk mengetahui efektivitas, penyerapan, dan hubungan serapan unsur hara nitrogen terhadap pertumbuhan bibit tanaman tebu. Percobaan dilakukan di Lahan KP 2 INSTIPER Yogyakarta Desa Wedomartani, Depok, Sleman, Yogyakarta pada bulan Mei 2022 – Juli 2022. Penelitian ini menggunakan metode rancangan faktorial satu faktor yang disusun dalam Rancangan Acak Lengkap (RAL). Faktor yang diuji adalah umur bibit tebu yang terbagi menjadi umur 8 minggu hingga 12 minggu dengan 3 kali ulangan. Media tanam yang digunakan dalam percobaan adalah tanah Latosol yang diberikan pupuk urea 14 g pada umur 9 minggu. Data diperoleh dari hasil pengamatan langsung dan uji laboratorium. Data yang diperoleh dari hasil penelitian dianalisis dengan menggunakan sidik ragam, perlakuan yang berpengaruh nyata diuji lanjut menggunakan uji duncan (DMRT) pada jenjang nyata 5%. Hasil penelitian menunjukkan terdapat pengaruh nyata antara lama waktu serapan hara nitrogen terhadap parameter pH tanah. Serapan unsur hara nitrogen meningkat seiring dengan penurunan pH tanah jika dibandingkan sebelum penambahan pupuk urea. Nitrogen providing is very important to increase the growth and yield of sugar cane plants. To find out the right time to fertilize, a plant uptake curve is needed during the plant's growth period. This research aims to determine the effectiveness, absorption and relationship between nitrogen nutrient absorption and the growth of sugarcane seedlings. The experiment was carried out on the KP 2 INSTIPER Yogyakarta Farm, Wedomartani Village, Depok, Sleman, Yogyakarta in May 2022 – July 2022. This research used a one-factor factorial design method arranged in a Completely Randomized Design (RAL). The factor tested was the age of the sugarcane seedlings which was divided into ages 8 weeks to 12 weeks with 3 repetitions. The planting medium used in the experiment was Latosol soil which was given 14 g urea fertilizer at 9 weeks of age. Data was obtained from direct observations and laboratory tests. Data obtained from the research results were analyzed using variance, treatments that had a significant effect were further tested using the Duncan test (DMRT) at a real level of 5%. The results of the research show that there is a real influence between the length of time for nitrogen nutrient uptake on soil pH parameters. Nitrogen nutrient uptake increased along with decreasing soil pH when compared to before the addition of urea fertilizer.

Abstract

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.

Abstract

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
