Corn is a superior agricultural product for the Giri Harjo I farmer group, Girikikis Village, Giriwoyo District, Wonogiri. However, farmers process and peel corn manually, so it takes a more time and inefficient. In order to overcome this problem, this community service designed and made a corn sheller machine that was used to simplify and increase the productivity in the corn harvesting process. This service activity begins with the delivery of the corn sheller machine to the farmer group, then exposure and training on the use of the machine. Corn shelling is accomplished by inserting the corn into the sheller shaft, after which the grinding knife separates the corn kernels from the cob. The shelling test results show that this machine works well, is practical to use, is highly portable, the production process is faster, the corncobs are not damaged, and the electric power consumption is low. This machine has a 0.5 HP motor and a production capacity of 183 kg/hour for shelling corn kernels.

Abstract. Subang Regency is one of the biggest corn producing regions in West Java besides Garut and Karawang. The average corn production in Subang Regency reached 1,318.4 tons or 1.2% (2008-2012) (Darmawan, Safei, & Hamdani, 2014). The quality and quantity of corn production is influenced by the process of handling the harvest and post-harvest. Post-harvest problems that are often experienced by farmers are the shrinking of the quantity and quality of maize yields due to the corn shelling process which is still done manually so that it is less efficient and low productivity. The purpose of this research is to produce a corn sheller machine that is simple, does not take up a large place in its placement, and is relatively inexpensive and easy to maintain. The method in this research is the study of literature, reading work drawings, making work preparations, preparing tools and materials, manufacturing processes, and testing the performance of tools. The results of this study are the corn sheller machine created with dimensions of length 500 cm, width 49 cm and height 100 cm, capacity of 2 kg / minute with 1400 rpm rotation. Based on the performance test results obtained that an increase in production capacity with a corn sheller machine that is 1 minute can produce 2.7 kg of shelled corn, while manually can only produce 1 ounce or 0.1 kg in 1 minute. So the comparison is obtained manually and machine that is 1: 27. In addition, the results of shelled corn has good quality or the seeds are not damaged. Keywords: Corn, Shelling Machine, Manufacture

During this time the process of making beberuk was still done traditionally using a mortar as a mixer, so that production is very limited, while the market demand is quite high. To increase productivity, it is necessary to design a machine that can increase the production capacity of the beberuk. The research method begins with the mixing machine design process, then continues with the assembly process and engine performance test. The design of the mixing machine is done with two approaches namely functional approach and structural approach. Test engine performance on 3 power variations namely 144, 168, and 192 watts and 3-time variations namely 30, 45, and 60 seconds. The results showed that the cylindrical mixing chamber has a diameter of 20 cm and a height of 50 cm. The mixing tube has a rectangular hopper with dimensions of 37 cm long and 9 cm wide. Engine performance test results showed the best results on 168 watts of power treatment and 30 seconds with the results of mixing not bubbly and still looks tomato chunks and is not too smooth according to the standard beberuk food.

This research is motivated by the low desire of students in writing travel reports. The lack of students' knowledge of the report concept, the lack of students' knowledge of the 5W + 1H report points of good and correct language, the lack of students' knowledge of the spatial, time and topic pattern and not yet reached KKM 75. The method used by the teacher has not been interesting, lecture method. The purpose of this study is to describe the skills of writing travel reports by using Round Club learning model which is viewed from the aspect of understanding the report concept, the use of 5W +1H report points, the spatial, time, and topic pattern.The population of this study is the students of class V Lessons Year 2017/2018 which amounted to 2 classes with the number 80. The sample of research as much as two classes taken by the sample of propotional.Class V.1 as experimental class and class V.2 as control class. The research instrument used is performance test. Provide an assessment by specifying the subject of the 5W + 1H report, as well as the spatial, time and topic pattern. Data were analyzed by 't' test by first testing normality, homogeneity, and hypothesis testing.The results showed that the average control class 68 with more than enough qualifications with standard deviation 16.96. 83 experimental class with good qualification and standard deviation of 15.42 and there is a significant influence on the result of writing skill of class V SDN 01 Nagari Bukik SikumpaSubdistrict, Lima Puluh Kota. This is evidenced by the average value of writing skills in the experiment class higher than the average value in the control class.

BACKGROUND: Few studies have investigated the variations in body composition and performance in Japanese collegiate American-football players. OBJECTIVE: To clarify what characterizes competitors at the highest levels – in the top division or on the starting lineup – we compared players’ body compositions and performance test results. METHODS: This study included 172 players. Each player’s body composition and performance (one-repetition maximum bench press, one-repetition maximum back squat, and vertical jump height) were measured; power was estimated from vertical jump height and body weight. Players were compared according to status (starter vs. non-starter), position (skill vs. linemen), and division (1 vs. 2). Regression analysis was performed to determine characteristics for being a starter. RESULTS: Players in higher divisions and who were starters were stronger and had more power, greater body size, and better performance test results. Players in skill positions were relatively stronger than those in linemen positions. Vertical jump height was a significant predictor of being a starter in Division 1. CONCLUSION: Power and vertical jump may be a deciding factor for playing as a starter or in a higher division.

Electric Power Steering System

Electric power steering is an advanced steering system that uses an electric motor to improve steering comfort of the car. As a result, the failures in the electric motor can lead to additional fault modes and cause damage of the electric power steering system performance. Hence, to ensure the stability of this latter, the present paper proposes a new method to reconfigure the fault control. A novelty approach of fast fault estimation based on adaptive observer is also proposed. Moreover, to guarantee optimal and fast control, a fault-tolerant control based on inverse bond graph modeling is designed to construct the behavior of the nominal system. The simulation and the experimental results on a real electric power steering system reveal the importance of the control strategy and show that the proposed approach works as intended.
