Abstract : Today, the application of technology to agriculture has become popular, and there are many applications for high-tech agriculture, from IoT systems to monitor the environment to agricultural robots. In this paper, the authors share the application of robots and computer vision in monitoring and serving production in cow farms. We build a group of moving robots to observe the living environment status of livestock, count the amount, divide the feed, and regulate the corresponding mode; this replaces human resources limited by time, response and continuous operation 24/7, reducing the burden of observation from fixed cameras when hidden corners cannot be observed. For the robot to move in the farm environment, the authors propose combining Lidar, a 3D camera, IMU for building digital maps and Utra-WideBand to update positioning values. The combination and integration of sensors on different map layers will evaluate the positioning efficiency..

Abstract : The article mentions the trend of management by cameras and robots, As cattle farms in Vietnam are increasingly growing in size, as well as the trend of integrating AIoT technology, controlling the living environment, physical condition, and the number of cattle... This is important because the epidemic and the disease spread in large herds, well controlled by technology to increase economic productivity and reduce risks. In this paper, the authors use AI training sets and tracking algorithms to help managers save time and statistics on animal behaviour and emotions, an area that other countries have studied. Development, however, there are still many limitations in the country..

Abstract : Today, with the strong field of AI, identification technologies have developed diverse applications. In this paper, the authors refer to bird identification by Yolo technology, thereby providing statistics on birds in agricultural areas and warning and repelling pests by laser. Different from radar, operating at high and long distances, it detects only flying objects; The camera system uses object detection algorithm that can flexibly detect close-range objects, and 3D camera technology combines the motion angle of the turntable system, which can accurately know the object in space..

Abstract : Mackerel is one type of seawater fish belonging to the pelagic group which has a distinctive delicious taste so that it is favored by the community. Mackerel fish can be found in Indonesian waters, especially in West Papua. Mackerel can be preserved through drying or fermentation processes, including Bekasam. The Bekasam is a fermented fish product that has a sour taste. During the fermentation process, there is the growth of lactic acid bacteria (LAB), and it is potential to be used as a probiotic candidate. The objective of this study was to determine the characteristics of LAB as probiotic candidates, and to determine the inhibition activity of LAB against pathogenic bacteria. This study is a descriptive study, which describes the characteristics of LAB cells as candidates for probiotic bacteria and also describes the ability of LAB to inhibit the growth of pathogenic bacteria. The results showed that of the six samples investigated, there were 3 samples of LAB that were potential as probiotic candidates, namely samples FST 1, FST 2, and FNT2. Furthermore, sample FST 2 showed the highest inhibition activity against Escherichia coli, while sample FNT 3 was not able to inhibit E. coli at all. Meanwhile, sample FNT 1 had the highest inhibition activity in inhibiting the growth of Salmonella typhimurium, while sample FST 2 was unable to inhibit S. typhimurium. Furthermore, sample FST 1 had the highest inhibition activity in inhibiting the growth of Staphylococcus aureus..

Abstract : Cultivation practices are considered as the main factors which affect the product quantity and quality of all plants. The aim of this paper is to present how the cluster thinning contribute on yield features and wine quality of the autochthonous Black Shesh red wine grapevine cultivar. The study was conducted during three consecutive years, 2019-2021. A RCBD with three replications and three variants with a plot size of 10 vines for variant was used. Three cluster thinning (CT) treatments were applied: control (no CT), 25% CT, and 50% CT. Cluster thinning was applied at berries pea-size (stage 75), consisting on removing the upper clusters on shoots. Leaf area per vine, number of clusters per vine, yield per plant, cluster weight, berry weight, TSS, TA, pH of must and wine, alcohol fraction for volume, wine color intensity, total phenolics, total and individual anthocyanin content, were recorded for a 3-year period. There was observed that two CT treatments significantly accelerated grape ripening by 5 and 9 days, reduced grape production per plant, raised cluster weight and berry weight, raised TSS content in must, while TA was reduced. Wine produced form CT treatments showed higher color intensity, higher alcohol content per volume, lower acidity, higher total and individual anthocyanin content. The highest quality wine, considering alcohol content per volume, total phenolics content, total and individual anthocyanin content, was achieved by 50% CT..
