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.

Explosive Reaction

Three syngases were selected from customer sites and the engine performance test was conducted on a single cylinder test engine (SCTE) to explore the engine operating limits and investigate the combustion characteristics for the simulation model development. Syngas has a wide range of lambda between the misfire and the detonation compared to conventional natural gas. Combustion of syngas 1 having no CH4 showed unique characteristics which are different from syngas 3. It appears that even a small amount of CH4 in the fuel would be important to lower the rate of the main branching reaction of hydrogen and mitigate the explosive reaction of the hydrogen. Lean operating limit of the tested syngas was observed when LFS (Laminar Flame Speed) and AFT (Adiabatic Flame Temperature) become around 5∼7 cm/s and 1660 ∼ 1720°C.

Main Engine

Early stage of engine valvetrain noise improvement involves the implementation of Design of Experiment (DOE) specifically the Taguchi methodology to identify the optimum valvetrain parameters which resulted in significant noise improvement. The parameters are consist of seven controlled factors such as cylinder head tappet bore diameter, mechanical tappet diameter, valve spring load, camshaft exhaust and intake waviness together with tappet exhaust and intake clearance. The confirmation run which was previously completed yields the valvetrain noise level at 67.07db SPL by 1 meter distance in completed vehicle during idling condition. In order to satisfy the final quality of the optimal valvetrain, a test is carried out to validate the performance curve on a dynamometer according to benchmark specification. The objective of the test is to validate the optimal valvetrain based on the experimental result which minimum manufacturing target shall be achieved to indicate that the engine is operated within its intended design. The performance test was conducted at the manufacturing plant on an eddy current dynamometer which runs for 11 hours. As results, the performance are within the standard with approximate increased by 6.9% as compared with baseline valvetrain and confirmed by several follow-up tests made on the improved valvetrain. In order to verify and address the main engine output of the optimal valvetrain, brake specific fuel consumption (BSFC) and emissions test results are then presented at the end of this paper.

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
