Abstract

Since the pandemic entered Indonesia, many people have switched to the online buying and selling transaction process.The Covid-19 pandemic has had a very significant impact on the transaction process which was previously carriedout traditionally, especially for the sale and purchase of sacrificial animals. The process of selling sacrificial animalsis still done traditionally by ordering directly by phone and coming directly to the cattle pen for the sacrificial animalsdesired by consumers. To deal with these problems, an alternative solution is needed that can create a informationsystem solution as a medium for selling livestock online. This online sacrificial animals buying and selling applicationwill be developed using the SCRUM method. When conditions change like this during the Covid-19 pandemic, SCRUMis suitable for developing applications. This is because Scrum is an iterative method that is included in the Agilemethod in how to manage and run an application development project. The features or menus that will be built in thisapplication including Master Data Management, and get Reports on all Transactions periodically, Shipping / DeliveryTransactions, notifications for Animal Husbandry Services. However, due to the conditions of the Covid-19 pandemic,there are several features that will be added, namely the Results of Routine Examination of the Condition of SacrificialAnimals for the last 1 month which will continue to be updated by livestock owners, and Description of PhysicalCondition of Sacrificial Animals which includes Species, Skin Color, Weight (Kg ), Height (cm).

Abstract

A common problem faced by four-legged robots is when they encounter obstacles that have structures that force the robot to lift its legs higher than the robot's ability limit and can disrupt the robot's balance, so it is necessary to add a gait control method. This research has resulted in controlling the movement of a four-legged robot using the wave gait control method to pass obstacles in the form of stairs and uneven floors, where the movement of the robot by lifting one leg at a time makes the balance of the robot very awake. So that the robot can make decisions if the robot encounters obstacles in the form of stairs and uneven floors, the role of the ultrasonic sensor is very decisive in reading the environment. The way for the robot to climb stairs and not fall backwards is to slide the robot's hind legs back so that each robotic footstep will form a triangle. When the robot detects the presence of a stairs, the robot will lift its legs by 50o, while when it detects an uneven floor, the robot's legs will lift its legs by 40o. Based on the results of research conducted with 4 experiments, namely the success of the robot in passing through the trajectory without obstacles by 100%, the success of the robot in crossing the uneven floor by 60%, the success of the robot in passing the stairs by 50%, while the success of the robot in passing the stairs and the uneven floor by 70%.

Abstract

Batteries have an important role in the development of energy needs. Good battery performance will support the devices it supports. The energy that can be stored in a battery is limited, so the battery will experience a cycle of charging and discharging. Improper charge and discharge processes can cause battery performance to decrease. Therefore, it is necessary to monitor battery performance in order to determine maximum battery performance. One of the aspects needed to monitor the state of charge and Depth of Discharge is to monitor the voltage, current and temperature on the types of lithium ion and lithium polymer batteries as energy storage for solar panels by using Arduino Atmega as a controller to determine the percentage of lithium ion and lithium polymer batteries and displayed on the LCD as HMI. From the results of comparing the performance of lithium ion and lithium polymer batteries, the results of SoC and DoD are measured and displayed on the LCD accurately, it can be seen which one is faster in charging time and lasts longer in use so that performance can be known of the two types of batteries.
