Abstract

Puslatdiksarmil is a military training and basic education center. To support the trainer in securing the grenadeduring the grenade throwing exercise, the author made "Design of Prototype Unmanned Grenade Tamer withWireless Control. This tool is used to assist the trainers in the implementation of handling unexploded grenades,by placing a detonator on the grenade then blasting. In the robot control application is very necessary ineveryday life and is very helpful in human activities that are dangerous and difficult to do by humans andtherefore we need an application that can control the robot remotely. In this Final Project, a robot has beendesigned that can be controlled remotely by air or wireless media as an application of a grenade tamer robot.Where the design of this robot will use an integrated robot with an actuator to drive the robot, a camera tomonitor the location of objects and its surroundings, and a wireless module that has been connected with the2.4 Ghz Tranciever so the robot can now be monitored remotely to perform operations.Keywords: Unmanned, Wireless, 2.4Ghz Frequency

Abstract

Low safety factor in the Standard Operating Procedure (SOP) in handling grenades that fail to explode at the training location can be fatal for personnel and instructors. In a previous study, a stick manipulator was designed. However, this tool has disadvantages because the operator is too close to explosives. By considering the security of personnel, the authors make "Design Robot Manipulator Build on Unmanned Grenade Tamer (UGT)". This tool is used to assist trainers and instructors in the implementation of laying explosives as a procedure for handling grenades that do not explode properly in position. The mechanism of this tool is made to complement the base tank that is driven by a robot remote control system that moves using a servo motor as an actuator. The total length of the horizontal arm stretch is 780 mm and 795 mm for the vertical stretch. Arm foundation is designed capable of rotating as far as 120⁰. Link 1 moves 150 °, link 2 150 °, Link 3 1801, and wrist roll 90 °. The force acting on link 1 is 16.758N in the direction of the y-axis parallel force, torque is 5.5 Nm and with an angular acceleration of 142rad / s². On the link 2 force of 16.66N, the direction of the force is parallel to the y axis, torque of 9.4 Nm and angular acceleration of 496rad / s². And on the 3 link force of 14.7N of torque of 3.3 Nm and angular acceleration of 293rad / s². The gripper gripping force is 1,158 kgf which is driven by a servo motor with a minimum torque of 5.42 Nm. Keywords: Robot arm, Torque, Gripper

Abstract

Lombok Strait is one of 9 chokepoints (narrow point) of the world. Lombok Strait is also one of the 3 lanes of the Indonesian Archipelagic Sea Lanes (IASL) contained in the IASL II which consists of the Makassar Strait and Lombok Strait. Lombok Strait has a depth of more than 150 meters and is a liaison between the Pacific Ocean and the Indian Ocean is very strategic for the submarine trajectory. So it is very important information about the water column in the Lombok Strait for military war operations needs. Therefore, the validity of accurate data is very important, by way of filtering CTD data. The goal is to know the thermocline characteristics and sound speed in the Lombok Strait. One of the methods used for CTD data filtering is by using Analysis Toolpak. Results from CTD data processing using Analysis Toolpak show that there is a difference between data profiles before and after filtering. It also can be seen that the characteristics of the thermocline of the Lombok Strait from North to South are increasingly tight or thin with a thickness of 146.094 meters to 87.694 meters. While the sound speed characteristics in the Lombok Strait from North to South direction also increasingly tight or thin with the difference in the value of sound speed from 34.547 m/s to 27.538 m/s. The seawater mass in the thermocline layer is thought to have originated from the North Pacific Intermediate Water (NPIW) which enters the Lombok Strait through the northern part of the Lombok Strait with an average salinity of 34,415 psu at an average depth of 42.504 meters. Based on the above data it is very important to filter the CTD data to produce valid and accurate data before further processing. Keywords: Filtering, Lombok Strait, Sound Speed, Thermocline.

Abstract

Several types of zinc anodes have been produced with a variety of different compositions. The variations in the composition of the zinc anode provide different corrosion protection performance. In this study, tested the characteristics of several zinc anode products and their performance in steel corrosion protection. The tests carried out included the composition test using the dry method and the wet method on KRI Zinc, Pure Zinc, and Commercial Zinc. The standard used is the US Military Specification (MIL - A - 18001 - H) standard. In addition to composition testing, the potential difference of each zinc anode is also taken, to determine the potential value of each zinc anode for protection potential, and also for cathodic protection. From the results of the dry composition test, a value that is easy to evaluate is obtained. For testing with the wet method, the value that comes out still needs to be converted to weight percent units. Of the three Zinc, which does not meet the US Mlitary Specification (MIL - A - 18001 - H) standard, namely commercial zinc, because there is an impurity in the form of Fe whose value is greater than the allowable amount of 0.005% according to the US Mlitary Specification (MIL - A - 18001 - H), which can interfere with the performance of the Zinc Anode itself. For the results of the potential difference test, the three Zinc can be used as a sacrificial anode in cathodic protection because there are impurities in the form of Fe whose value is greater than the allowable amount of 0.005% according to the US Military Specification (MIL - A - 18001 - H) standard, which can interfere with the performance of the Zinc Anode itself. For the results of the potential difference test, the three Zinc can be used as a sacrificial anode in cathodic protection because there are impurities in the form of Fe whose value is greater than the allowable amount of 0.005% according to the US Military Specification (MIL - A - 18001 - H) standard, which can interfere with the performance of the Zinc Anode itself. For the results of the potential difference test, the three Zinc can be used as a sacrificial anode in cathodic protection. Keywords: zinc anode, offering anode, protection potential.

Abstract

The ability to carry out the maintenance and repair of Warships of the Republic of Indonesia / naval vessels is a concept used in assessing the achievement of work with time parameters and measures of success. Budget, infrastructure and human resources have an important role in the task of maintenance and repair facilities surabaya. Every maintenance and repair always expects the implementation of the work to be completed on time, and the maximum results, so that the ability to maintain and repair needs to be maintained and improved on the implementation of the work. There are several alternative factors that can lead to improved maintenance and repair capabilities of warships of the Republic of Indonesia / Naval vessels including budget allocation, supporting infrastructure directly or indirectly as well as the readiness of human resources that include willingness, experience and expertise. These factors have an interconnected pattern. This study aims to find out the main factors that affect the improvement of the ability to maintain and repair KRI / KAL in mako koarmada II. In this study used a measuring instrument called dynamic system method with stella software. Factors that affect the improvement of capabilities in the literature can be from the literature whereas, the determination of the main factors that affect is done by modeling dynamic systems. This dynamic system modeling is done by creating a dynamic relationship between the factors that affect productivity. The data collection in this study uses secondary data from the process of maintenance and repair of fasharkan in Surabaya. The scale of the data used to determine the factors that influence the improvement of the ability is modeled in qualitative form. The result of modeling dynamic system factors that affect the improvement of capability is budget, infrastructure facilities and human resources factors that dominate are human resource factors. Keywords: Proficiency, Dynamic System, Stella Software
