Bolting machine is a machine which is designed to conduct the making process of outside thread without rotating the handlebar of workpiece using hand manually, Therefore, the machine can help the processing in some industries which do not have qualified operators. The purpose of the designing and calculating of machine elements on senai machineis to create a design and make it in real product that can create outside thread with the maximum size of M11, to calculate parts of machine elements, i.e. axis diameter and sprocket chain and to create the real machine product. The designing method used follows these steps, i.e. problem identification, initial idea, improvement of the idea, analysis of design, decision making, and implementation. The result of the evaluation on concept design was the cutter holder on the chuck variable and themover shaft handle. The result of machine elements calculation showed that the electric motor power was 40 watt, shaft diameter was 25 mm with inside diameter of 16 mm, the bearing used was 6205 Ball Bearing, and the thread capacity was M11 metric thread.

Diesel engines are widely used as driving forces in vehicles and industry due to fuel efficiency and high output power. The wide use of diesel engines triggers an increase in fuel consumption and exhaust emissions that are harmful to health. Jatropha is a renewable fuel as a solution to increase fuel consumption. However, the high viscosity and low calorific value result in reduced performance and increased exhaust emissions. Butanol has a high oxygen content and cetane number and low viscosity compared to diesel and jatropha. Addition of butanol is possible to reduce the decrease in performance and exhaust emissions of diesel engines. this study evaluates the effect of butanol on reducing Isuzu 4JB1 diesel engine direct injection emissions. Percentage of blend used 70/30/0, 65/30/5, 60/30/10, and 55/40/15 based on volume. Tests are carried out at 2500 constant turns with a loading of 25% to 100% using the EGR system. The experimental results showed the presence of butanol caused a decrease in soot emissions produced by diesel engines

Information about UMKM is very much needed by the Cooperative Office of UMKM in determining the direction of MSME development. Accurate data will have the right impact in determining development programs and services for SMEs. The problem that often occurs in managing UMKM data and Consultation is that management is still done manually using a book, so the risk for data loss, double data, and data retrieval are difficult when data is needed quickly. So based on these problems it is necessary to have an Information System to manage MSME data. The method used is the waterfall software development method. The results of this study are systems that can facilitate datamanagement, speed up the data search process, classify according to criteria so that it can be used as a reference in the development and service of MSMEs and assist cooperative service consultants in the business consultation process.

The confession of professionalism can be stated in the form of sertificate awarding to lecturer bycompetent institutions. The best effort that needed for comitting certified lecturer until it is tried to be able to increase the quality of state polytechnic of Cilacap because of lecturer is the most important component to determine learning activity process. The lack of preparation will cause the lecturer who recommended on certified lecturer can not pass well. The simulation of intern score calculation of certified lecturer will be conducted by institution through committee of certified lecturer. This research focuses on the simulation of intern score calculation of certified lecturer which recommended. The method that used was software development method, i.e., prototyping. The finding of this research is this system can help to simulate the data of score evaluation. The committee of certified lecturer will be easy to make decision in committing certified lecturer and the calculation of automatic simulation score will decrease errors in calculating total score of certified lecturer.
