A census of eddies in the tropical eastern boundary of the Indian Ocean
The Indo-Australian Basin (IAB) constitutes a crucial water route for the global ocean's circulation between the Pacific and Indian Oceans. Locally generated eddies contribute to the continued westward transport of water away from the IAB. In this paper, results from the first comprehensive regional ocean eddy census are discussed. A hybrid eddy census and tracking algorithm is used to analyze satellite altimetry data from 1993 to 2018. A total of 2,792 eddies were identified and tracked. Cyclonic eddies and anticyclonic eddies exhibit geographical segregation in terms of their dynamic characteristics. Larger amplitudes, radii, and absolute vorticities are associated with high eddy kinetic energy regions located in the vicinity of the South Java Current, South Equatorial Current, and Indonesian Throughflow. The eddies are grouped into three duration-based classifications providing the first systematic insight into understanding their physical characteristics, formation, and distribution in the IAB

Young Children’s Drawings of Plant Life: A Study Concerning the Use of Colours and its Relationship with Age
Processing Mchine, Refrigerator and Milk Packaging System with 3-in-1 Integrated Process
The purpose The purpose of this study is to provide solutions to problems that exist in SMEs Cow Milk Momoo, especially the problem of production processes that the process is still using the traditional way and the tool is still relatively simple.
Method The method used is to utilize Temperature Controller on Processing Machine, cooling, and packing Cow Milk that serves to regulate the cooking temperature so that the heat generated can be more evenly distributed. Processing, refrigeration and packing machines Cow Milk is also equipped with a Wiper Motor instead of stirring which is still manual so that the stirring process can run automatically. In addition to this machine also uses Heat Exchangers technology soaked in water so as to be able to overcome the problem of cooling process is still simple.
Results The expected result is the increased productivity and efficiency of the production process so that the productivity of SMEs of Cow Milk Momoo can increase 2-fold which initially yields an average of 150 liters of Cow Milk / day can produce up to 300 liters of Cow Milk / day.
The Findings The findings of this research are the use of Temperature Controller, Wiper Motor, and Heat Exchanger as solution of SMEs Cow Milk Production Process Problem.

Identifikasi Borneo Vortex terhadap Dinamika Suhu Permukaan Laut di Laut Jawa
The event of Borneo Vortex is a disruption of the synoptic scale that occurs when the Asian monsoon is active. Borneo Vortex occurs because of the interaction of the Asian monsoon winds with the wind from the southeast in the northwest region of Borneo so that the vortex is formed which can increase rainfall. Related with rainfall, Sea Surface Temperature (SST) becomes one of the factors that influence it. The purpose of this study is to examine the effect of Borneo Vortex on the dynamics of Sea Surface Temperatures in the Java Sea. The impact of Borneo Vortex, SST parameter becomes dynamic and very important to influence the condition of waters in Java Sea. Data used in this research is ERA Interim ECMWF (European Center for Medium-Range Weather Forecast) Reanalysis data in the form of wind component u and v, vortisitas relative, divergence, and specific humidity. Rainfall analysis is done using daily rainfall data of 3B42RT TRMM (Tropical Rainfall Measuring Mission), while SST data uses the data of Visualize NOAA (National Oceanic and Atmospheric Administration) High Resolution Blended Analysis Data. The Sea Surface Temperature analysis was performed using Remote Sensing data from the period of December until February (DJF) 2004/05 to 2014/15. The method used is to find the composite value of each parameter at the time of Borneo Vortex event during the time of research. The results identify that the largest event of Borneo Vortex was in December. With the presence of Borneo Vortex, there is a significant change in vorticity, divergence, moisture transport, rainfall, and SST. The impact of Borneo Vortex can increase rainfall and increase SST in the Java Sea. Borneo Vortex occurred in December January February at the time of an active Asian monsoon in northwest Borneo where there is a synoptic scale disorder in the form of a massive air vortex causing an increase in rainfall and the dynamics of SST tend to rise as well
