This paper discusses the comparison of the Saturation Height Function between the saturation calculation method based on log data using various equations such as Archie, Indonesia and Dual Water with the empirical method which is popularly used in the oil and gas industry, namely the Cuddy method. The advantages and disadvantages of each method will be discussed. Each method of calculating saturation with log data is compared with the Cuddy method to get an idea of which geological conditions are most suitable for the Cuddy method. This study was carried out by modeling the well oil saturation height profile from an Oligocene well from the North West Java Basin of Indonesia. This well was chosen because it did not have complete data, only a series of Electrical logs and no conventional core and SCAL data. Apart from comparing each method on the well, this paper also compares volumetric calculations based on the resulting oil saturation height profile model.By comparing the results of each volumetric calculation, we can find out which method gives better results so that without core data we can still make STOIIP predictions quite validly.

The head loss in water flowing through pipes often turns out to be different from what we assume, which is the occurrence of incompressible flow. However, this assumption is not always true because the flow pattern inside the pipe is not visible and can only be measured with precise equipment. The presence of water in the pipes can only be tested on a clear scale, especially when it is part of the network within a multi-story building. Determining the need for a pipe network within a building is not an easy calculation due to differences in length, diameter, and bends. Hydraulic experts often overlook these differences, which can become a problem when clogs occur during the flow process. To find a solution to this problem, it is necessary to conduct tests using a device called a Water Measurement Unit. This is rarely done in laboratories. Testing the water pressure with this device requires various instruments and a variety of valve openings supplied with pressurized water by a pump at a certain capacity. To analyze the flow rates resulting from the tests with different valve openings, researchers test and measure the flow rate capacity for each opening, starting with openings of 0.5, 0.75, 1.00, and so on. They read the instrument, move the copper from one height to another, and create a graph of the test results in the form of a pair of connectors. The researchers test the device and its openings three times for each opening, recording and mapping the pressure values and the time it takes on the measuring instrument. Subsequently, the results of the pressure test (Head Loss) are recommended to provide information to water pipe installation planners that the test results with various valve openings under certain conditions have different pressure values and travel times. It turns out that in the placement of hose or copper number 2, stability is observed with pressure, and there is no significant differential pressure increase. In the experiment with hose or copper number 2, it can be said that everything is stable enough to conclude that there is no head loss, and it is recommended to be safe for modeling.

This research aims to develop an e-commerce service application model for Micro, Small, and Medium Enterprises (MSMEs) that facilitates the sale of MSME products online. The application model allows MSMEs to expand market reach and sell products more efficiently through the internet. In this application, data about customer locations, product locations, and information about available road networks are collected and entered into the system. Furthermore, using Dijkstra's method, the shortest route from the initial location or distribution point to the customer can be calculated automatically by considering factors such as distance, time, and transportation that may affect the speed of delivery. The MSMEs e-commerce service application model can optimize distribution and delivery with the aim of increasing the competitiveness and growth of MSMEs in the digital era. The results obtained in this study provide guidance and contributions in the development of a sustainable e-commerce system for MSMEs.

The types of hydraulic flow patterns in laboratory testing through the use of physical modeling tools often encounter several challenges when confronted with the use of empirical model scales, namely, the issue of scale. Water structures in the horizontal dimension do not experience highly complex issues because there are many measuring instruments available, whether self-made, home industry-produced, or industrial-grade. The presence of water volume in storage can only be tested at a clear scale, especially when it is already within a water tower (reservoir) installation with a specific height. Determining the need for water storage in a water tower is not an easy task to calculate due to differences in height, diameter, and storage capacity. Hydraulic experts often overlook these differences, which can become a problem when there is a demand for the volume of water during peak flow conditions. The solution to this issue needs to be verified by conducting model tests using a device known as the Centrifugal Pump, which has not been previously explored for laboratory research. GPM LPM model tests on this device make use of instruments and numerous pressure measuring tools supplied with pressurized water by a pump at specific, measurable volumes. To analyze the flow rate, flow coefficients, flow velocity, Reynolds number, Froude number, and test results with various speeds (speed meter), researchers test and measure the capacity of GPM LPM for each valve opening, starting with openings of 0.5, 0.75, 1.00, reading the instruments, shifting the speed from 1, 2, 3, 4, up to the highest speed, which is 12. A graph is created to display the test results of the GPM LPM speed booster device, which contains an electric motor. The test is conducted with three repetitions for each valve opening, and the speed and travel time values from the instruments on the test device are recorded and mapped. Subsequently, the analysis results of the GPM LPM test are recommended to provide information to construction planners of water structures. These results show that, under specific conditions of different speeds and valve openings, there are variations in the volume and travel time values. This information can be applied to determine the required storage capacity for each water tower building with a hydraulic flow pattern based on Reynolds number (Re) and Froude number (Fr).

Autonomous vehicles are around us and are finding trillions of recent developed applications, starting from driverless cars to automatically observation in critical areas. Continual progress in these technologies within the earlier decades makes these inventions possible. However, the planning of these technologies which must be surmounted, to apply efficient, useful supremely important and safe tasks of those independent units are daunting as well as numerous. Over the past decade, many researches are published within the domain of autonomous vehicles. Yet, most of them concentrate only on a selected technological area, such as vehicle control, visual environment perception ... etc. During this paper we present a brief yet comprehensive overview on the most significant key ingredients of autonomous cars, it covers almost all bases, from available models and types, their functions, importance, in addition to the most important related work.

The intelligent egg incubator is designed to improve existing egg incubators to transform the traditional breeding method into a modern and advanced breeding method. To reduce the chore that traditional breeding methods can cause, the use of an automatic incubator is therefore recommended to ensure the best possible hatching rate. Automatic incubators also allow you to control heat and humidity levels to reproduce ideal brooding conditions. The main objective of this work is to design an egg incubation system that performs better than manual incubation. The proposed system is an innovation that makes it possible to monitor the temperature, humidity and movement of the egg inside the incubator thanks to a data acquisition system taking into account the physiological conditions of the eggs. The proposed system is equipped with a Wi-Fi module via the ESP32, allowing the system to be manipulated remotely.
