Small and middle enterprises have been the important part of the economic of a nation or a local. Karang Write-Batik is one industrial center which is located at Karang Village, Semanding Subdistrict, Tuban District. Early observation shows that various processes within the production of Write-Batik are conducted without considering ergonomic aspects, such as work method and work facility. It may result in complaint and even muscle injury which is called Musculoskeletal Disorders (MSD’s) Many pronlem of pain perceived by workers are caused by less ergonomic work position or work posture. It may also be evident because the less correspondence between work equipment and workers’ anthropometry size. To measure workers’ musculoskeletal injured, the author uses Standard Nordic Questionnaire (SNQ) and to assess work posture, Quick Exposure Check (QEC) is used. The reduction of workers’ musculoskeletal injuredt can be realized by improving work facility based on workers’ anthropometry size. Result of early measurement of exposure level of several parts of body indicates that the exposure level of the back is 26, while that of the arm is 30, that of the hand wrist is 26, and that of the neck is 16. After the improvement of work facility, workers’ complaint is reduced and so is exposure level. The exposure level with the improved work facility is shown as follows: the exposure level of the back is 22, while that of the arm is 22, that of the hand wrist is 22 and that of the neck is 14.

Weapons Industy has the greatest asset in the production of klongsong with various varians meet the basic needs of military and public supplies, klongsong types 6 mm. Improving in quality does is not mean to increase the amount of labor or replace the old machine with a new one but rather to maximize the performance of the production system elements. This research is proposed to reduce the reject rate klongsong 6 mm process and to to determine the factors that influence the defective product. Six Sigma concept is used to discover and to reduce the factors that cause disability and error so as to improve the quality to wards zero failure rate. Six Sigma framework is known as Define, Measure, Analyse, Improve, and Control (DMAIC). In Define phase of DMAIC is to define CTQ (Critical-To-Quality) through interviews with company management. In the Measure phase of DMAIC level of product quality (products klongsong 6 mm casing) is measured. In Analysis phase of DMAIC the causes of defects is analyzed through Ishikawa diagram. In Improve phase of DMAIC the preparation of the proposed improvements is based on is based on prioritization using FMEA. The results of the analysis of the application of Six Sigma in production klongsong in average was 4.69 with DPMO 695.429.

Daya dan efisiensi merupakan parameter – parameter yang menjadi tolak ukur dari kinerja sebuah turbin kinetik. Penelitian sebelumnya menunjukan berbagai faktor seperti debit aliran, dimensi dan geometri dari turbin kinetik adalah varaibel – variabel yang mempengaruhi besarnya daya dan efisiensi. Dalam upaya meningkatkan kinerja turbin kinetik dibutuhkan pemahaman yang mendalam terhadap faktor – faktor yang mempengaruhinya. Oleh karena itu tujuan dari penelitian ini adalah untuk mengetahui pengaruh variasi lebar sudu mangkok terhadap kinerja turbin kinetik. Metode yang digunakan dalam penelitian ini adalah eksperimental nyata pada skala laboratorium. Pengujian dilakukan pada turbin kinetik poros vertikal dengan variasi lebar sudu 8 cm, 9 cm dan 10 cm. Setiap turbin diuji pada variasi debit air 45 m3/h, 50 m3/h, 55 m3/h, 60 m3/h dan 65 m3/h dan variasi putaran 20 rpm, 40 rpm, 60 rpm, 80 rpm dan 100 rpm. Hasil penelitian menunjukan bahwa lebar sudu mangkok mempengaruhi kinerja dari turbin kinetik dimana lebar sudu mangkok 10 cm memiliki kinerja lebih tinggi dari lebar sudu mangkok 8 cm dan 9 cm. Kinerja tertinggi turbin kinetik pada variasi lebar sudu mangkok 10 cm diperoleh pada kondisi putaran 80 rpm dan debit 65 m3/h. Pada kondisi tersebut daya yang dihasilkan oleh turbin kinetik adalah 12,98 Watt dan efisiensinya 35,72 %.

Abstractâ€” Processing of natural fibers as a support material for composite materials has been widely carried out. Some studies use chemicals as a medium for processing fiber while the treatment with natural ingredients has not been done much. This study discusses the ability of the matrix to penetrate the coconut fiber. Coconut fiber that has been cleaned soaked in a solution of limestone water. Immersion is done with a variation of the lime mass percentage of 0; 2.5; 5; 7.5; 10% with 8 hours soaking time. The matrix used is unsaturated polyester yucalac 157 BQTN-EX. Wettability testing by dripping a matrix on coconut fiber. Coconut coir fibers that have been dripped with a matrix in the photo to determine the contact angle. The results of measurements and observations that with variations in mass percentage of 5% limestone with an immersion time of 8 hours have a contact angle of 11OË‚Î¦Ë‚31O. Immersion with a percentage of 2.5% shows the surface of the fiber has not changed. Immersion of 7.5% and 10% of the surface of the fiber has been damaged, so the matrix can not absorb the coconut fiber to the maximum.Â Keywordsâ€”: coconut fiber; limestone water; contact angle; wettability; SEM.

Power and efficiency are parameters that show the performance of a kinetic turbine. Previous studies have shown various factors such as flowrate, dimensions and geometry of kinetic turbines are variables that affect the magnitude of power and efficiency. In an effort to improve the performance of kinetic turbines it takes a deep understanding of the factors that influence it. Therefore the purpose of this study was to determine the effect of width variations of bowl blades on kinetic turbine performance. The method used in this study was real experimental on a laboratory scale. Tests were carried out on vertical shaft kinetic turbines with blade width variations of 8 cm, 9 cm and 10 cm. Each turbine is tested on variations of water discharge 45 m3/h, 50 m3/h, 55 m3/h, 60 m3/h and 65 m3/h and in rotation of 80 rpm. The results showed that the width of the bowl affected the performance of the kinetic turbine where the width of the 10 cm bowl blade had a higher performance than the width of the bowl blade 8 cm and 9 cm. The highest performance of kinetic turbines in the variation of the width of the 10 cm bowl blade was obtained at discharge conditions of 65 m3/h. In these conditions the power produced by the kinetic turbine is 12.98 Watts and the efficiency is 35.72%.
