Abstract

The purpose of this study is to improve theproduction process of brick craftsmen. Brick production processconsists of four stages: printing, drying, burning, and cooling. Ofthe four stages, which will be completed in this research is theprocess of printing bricks. The printing process still uses simpleequipment that is a rectangular wooden beam with a size of 20cm x 10 cm x 5 cm. The printing process includes: preparation ofraw materials by hoeing the soil, making the dough by tramplingto the shape of a paste, printing using a printing tool. For thismethod, for 4 people craftsmen can print bricks as much as 2,000pieces / day (8 hours work / day). The number of bricks is idealfor once combustion of 40,000 pieces. For reach that amount ittakes 20 days. The method applied in improving the productionprocess of brick craftsmen is the application of brick machine.The operation of the brick printing machine requires 4 personswith their respective functions: 1 person to insert the soil into theprinting machine, 1 person to cut the brick bar, 1 person to movethe bricks from the printing machine, 1 person to bring thebricks to the drying place. Based on the result of the test, it isconcluded that by using the brick machine, the dough making iseasier and shorter, the production capacity increased to 6,780bricks / day, the time required for the production of 40,000 piecesof bricks is 6 days.

Abstract

The general goal of this research is to help provide a means to train the muscles of the sufferers Cerebral Palsy (CP). In especially, the objectives are: (1) Make a seat that has a function like easy stand, (2) Provide easy stand chair at a price affordable by people suffering from CP. Problems to be solved through applied product research activities are (1) how to make a chair that has functions such as easy stand, (2) how to provide easy chair seat with low price that can be reached by CP sufferer. To achieve these goals be done designing and making a chair similar to chair easy stand for people with CP. Stages of activities include designing, manufacturing components, assembling, testing and repair. Based on the test results, it is concluded that the celebral palsi chairs function well, including the components such as knee retention, peut holder, and table. The price of one CP chair is Rp 10 million.

Abstract

Tujuan Penelitian ini ialah mengetahui pengaruh perlakuan serat sabut kelapa terhadap kekuatan tarik komposit serat sabut kelapa. Untuk mengetahui hal tersebut, maka komposit dibuat (1) dengan serat sabut kelapa tanpa perlakuan NaOH tanpa pemanasan, dan dengan serat sabut kelapa dengan perlakuan NaOH dan pemanasan dalam oven. Konsentrasi NaOH yang digunakan ialah 5%, 10%, dan 15% v/v dengan lama perendaman 45 menit. Serat sabut kelapa yang telah direndam NaOH tersebut kemudian dipanaskan dalam tungku pada temperatur 70oC selama 5 jam. Bahan-bahan yang digunakan dalam penelitian ini yaitu serat sabut kelapa, NaOH, aquades, resin poliester, katalis MEKPO, gemuk, dan seperangkat alat cetak yang terbuat dari kaca dengan ketebalan 5 mm. Metoda yang digunakan dalam pembutan komposit ialah metode hand lay up yaitu cetakan diolesi gemuk, kemudian resin dituang ke dalam cetakan, kemudian serat sabut kelapa dimasukkan dan disusun secara acak, selanjutnya resin dituang lagi kedalam cetakan, kemudian ditutup dengan kaca sambil ditekan untuk mendapatkan permukaan yang rata. Sedangkan untuk mengetahui kekuatan komposit dilakukan pengujian tarik. Hasil yang diperoleh yaitu nilai kekuatan tarik komposit yang diperkuat serat sabut kelapa meningkat menjadi 24,51.106 N/mm2 dibandingkan dengan komposit tanpa serat sabut kelapa yaitu 12,98.106 N/mm2. Sama halnya komposit dengan komposit serat sabut kelapa yang diberi perlakuan NaOH, kekuatan tariknya juga meningkat sebanding dengan peningkatan kadar NaOH. Kekuatan tarik tertinggi diperoleh pada konsentrasi NaOH 15% v/v yaitu 15,41.106 N/mm2. Hal ini juga terjadi pada komposit dengan perlakuan serat sabut kelapa NaOH dan pemanasan. Kekuatan tarik tertinggi diperoleh pada konsentrasi NaOH 15% sebesar masing-masing 26,76.106 N/mm2. Kesimpulan yang diperoleh bahwa serat sabut kelapa,dan perlakuan serat sabut kelapa berpengaruh terhadap kekuatan tarik komposit serat sabut kelapa.
