The Determination of Mycotoxins in the Composition of Walnut (Juglans Regia L.) Fruits Cultivated in Different Geographical Regions of Uzbekistan by High–Performance Liquid Chromatography Method and Their Comparative Analysis

/in /by

Mycotoxins are secondary metabolites produced by various fungi and are known to have significant adverse effects on human and animal health. If food products are contaminated with mycotoxins, their toxicity can cause various diseases. In this scientific research work, residual mycotoxins in nutrients were combined with liquid–liquid extraction (LLE) and analyzed through the use of reversed–phase high–performance liquid chromatography (RP–HPLC). These scientific studies were conducted in the experimental biology laboratory of Gulistan State University to determine the amount of aflatoxin (AFB2, AFG1, AFG2) in the samples of walnuts cultivated in six regions of Uzbekistan. The study revealed the detection of aflatoxins AFG1 type 0.003 in the designated region labeled as S20, AFB2 and AFG2 0.001 in J25, and AFG2 0.002 in S30. However, it is important to note that these levels did not above the maximum residue level standards established by the Republic of Uzbekistan. However, the aflatoxins produced by fungi are released based on the development of fungi at a temperature of 25–3000C, therefore it is recommended to store walnut fruits in dry conditions at a temperature of 1500C. All the methods used during scientific analysis can demonstrate high sensitivity and accuracy. All methods are successfully used to identify mycotoxins in the composition of walnut fruits, separate them from fungi and specify the amount of ingredients.

Predictive Analysis for Inventory Management of Coconut Warehouse (Case Study: Banio Lahewa)

/in /by

Inventory management plays a pivotal role in the coconut farming business, directly influencing sales and income. An essential component of this management is warehousing, which not only affect revenue but also involves suppliers in the coconut storage process. Warehousing management and technology are two elements that can help companies operate more effectively and efficiently. This research focuses on efforts to improve warehouse management efficiency in the agricultural sector, particularly at Banio Lahewa, a company that operates as a coconut supplier in a small village with limited resources. Currently, the company still records data manually and lacks a real-time system to monitor demand patterns, stock rotation, and restocking frequency in the warehouse. This situation is caused by uncertainty about the products entering the warehouse, leading to the company’s focus being more limited to daily operational issues rather than future planning. To address this challenge, this research uses future event prediction methods, specifically forecasting by applying two neural network models: the Feed Forward Neural Network and the Long Short Term Memory. The implementation of this system is expected to provide new insights to the company, enabling them to be more adaptive in efficiently managing warehouse systems. With an understanding of patterns and predictions of future events, it is expected that the company can be more prepared and responsive to changes in customer demand and able to expand products more quickly. The results of this research are expected to make a positive contribution to the company, helping them optimize warehouse management and become more adaptive to market dynamics.

Vertical Space Use and Vegetation Characteristics of Reintroduced Orangutan Activities in the Jantho Nature Reserve

/in /by

Orangutans are a wild animal species that is threatened with extinction, so the IUCN has designated its conservation status as Critical Endangered and Appendix I in CITES. The Indonesian government has also designated the Sumatran orangutan as a protected animal. Jantho Nature Reserve (JNR) is one of the conservation areas that is used as a place for orangutan reintroduction. This area is also an important habitat for seven other primate animals. On the other hand, reintroduced orangutans are arboreal animals that have become accustomed to the human environment. They do not know the types of trees that source their food, and the predators that endanger them. This will be a threat to the sustainability of reintroduced orangutans in the area. This research is important to carry out because there is still very little information regarding the use of vertical space in the daily movements of reintroduced orangutans, and there is no information about the daily movements of reintroduced orangutans in the JNR area. This research aims to obtain initial data on the daily movement patterns of reintroduced orangutans in utilizing vertical space to obtain food sources. The transect route is a method used to obtain data on the movement of reintroduced orangutans. A total of 5 line transects were used to collect data by following the reintroduced orangutans and recording each canopy height used by the orangutans for activities. The data obtained was made in tabulated form and analyzed descriptively. The research results showed that reintroduced orangutans used vertical space at a height of 1 – 29 m. This height level was different for the four reintroduced orangutans observed. molikha has higher activity at a height of 1 – 10 m. Poni activity is highest at a height of 10 – 19 m. Cut keke and asokha use higher vertical space at a height of 20 -30 m. A total of 34 trees were used as reintroduced orangutans as activity sites, with tree heights of 1 – 30 m and trunk diameters of 1 – 200 cm. Vegetation connectivity is still connected between vegetation.

Comparison of Energy Dissipation in Ogee and Stepped Spillway Using the Fluent Software

/in /by

One of the essential components of any dam is the spillway, which stands as one of the oldest man-made hydraulic structures. It serves as a device designed for the measurement and regulation of water flow, facilitating the controlled passage of excess water and sediment from the upstream to the downstream. This structure finds extensive application in dam construction. Given the critical nature of its function, a stepped spillway demands robust and reliable instruments to ensure high efficiency, ready for use at any moment. Providing crucial information about the behaviour of this significant structure, including flow characteristics such as the flow curve, water level profile, pressure, and velocity pattern at different points of the flow, is essential for its design, monitoring, and safety program. In this research, the Fluent software was employed, utilizing the RSM turbulence mode for simulating the flow on both Ogee and stepped spillways. The comparison of energy loss in these spillways was conducted, employing the VOF model to trace the free flow surface. The obtained results were validated using previous researchers’ studies.

/in /by

This research was conducted with the aim of gathering information on the motivations of female tourists to make repeat visits to Yogyakarta. Women were chosen as respondents because women are considered to have maturity and make better decisions in their families, as well in tourism activities. The research was conducted using a non-probability sampling model on 100 respondents who had finished their trip. The survey was carried out at tourist entry points such as at tourist attraction locations, railway stations and airports. There are three variables tested, namely Perceived Satisfaction of Cultural Attraction (CUL), Perceived Satisfaction of Natural Attraction (NAT), and Perceived Satisfaction of Shopping and Culinary Attraction (ShoC). Using the classic assumption test and multiple linear regression, the results show that female travellers have the intention of making a return visit (RI) because of the satisfaction factor on cultural tourist attraction (CUL) and the satisfaction factor on shopping and culinary attraction (ShoC). The attractiveness of Natural Attraction (NAT) does not significantly influence female travellers having intention to revisit.
