Abstract

Lathe is a tool that rotates the work-piece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, or deformation, facing, turning, with tools that are applied to the work-piece to create an object with symmetry about that axis. There are several considerations that affect the lathe to work well, especially geometrical deviations that affect the quality degradation of the product in terms of shape and dimensions. One of the wear on the slide-way of the lathe can affect geometric aberrations. This paper discusses the design and manufacture of grinding tools to fix the lathes bed that can erode three slide-way planes in a single process to achieve flatness and square alignment with one another. The research method used is the experimental method by collecting the data needed to design the tool through literature study and direct observation to the lathe, then the data is processed to obtain the specification of the tool that will be designed by design method based on Verien Deutche Ingenieuer (VDI) 222 , the design result is then continued with the machining and fabrication process; before assembling, parts of the auxiliary equipment are tested in accordance with the design function indicator; the last stage is testing the tool as a whole to know the achievement of the tool against a predetermined goal. Based on the results of the grinding experiment on the three slideway planes with a feed depth of 0.03mm, the average flatness and alignment values ??are 0.02mm / 300mm and 0.07mm / 300mm, respectively. Based on the ISO 1708 standard on the tolerance of geometrical deviations, the grinding results have not allowed the tolerance. Still need more research about the influence of wear of grinding wheels to the grinding results.

Abstract

Green manufacturing adalah konsep sistem produksi berkelanjutan dalam menghasilkan sebuah produk, dengan meminimalkan limbah dan polusi di dalam prosesnya. Salah satu penilaian kinerja green manufacturing adalah program PROPER yaitu program peringkat kinerja perusahaan oleh kementrian lingkungan hidup. PT X adalah pabrik yang memproduksi brankas atau lemari besi dan filing cabinet tahan api. Limbah yang diolah di Instalasi Pengolahan Air Limbah berasal dari proses painting baik dari bahan kimia proses pembersihan pengkondisian metal sebelum dicat, maupun dari material cat itu sendiri. Limbah juga datang dari sisa campuran beton yang merupakan bahan utama sebagai pengisi lemari besi. Proses pengolahan limbah menggunakan metoda fisik dan kimia agar buangan limbah memenuhi baku mutu Kawasan Industri MM2100 Bekasi. Kajian ini dilakukan untuk merekayasa campuran beton dengan memanfaatkan limbah sludge dan rekayasa instalasi air untuk memanfaatkan air limbah menjadi air penunjang proses produksi. Kajian dilakukan dengan cara mengumpulkan data primer dan sekunder, pengamatan langsung ke lapangan, pengambilan dan pengujian sampel. Pembuatan sampel kubus beton dilakukan untuk subtitusi sludge 0%, 5%, 10%, 15% dan 20% masing-masing 3 sample untuk Uji Tekan 7 hari dan 3 sample untuk Uji Tekan 28 hari. Dari hasil pengujian di ketahui nilai kuat tekan subtitusi 10 % sebesar 310 (kN), lebih besar dari nilai minimum yaitu 300 (kN) sehingga bisa di gunakan sebagai campuran beton produk. Subtitusi 5% sampai dengan 20% bisa digunakan untuk ruko 5 lantai s/d jalan tol atau jalan negara.

Abstract

Penelitian ini bertujuan untuk mengetahui respon pertumbuhan kambing jantan yang diberikan ransum tanpa fermentasi dan ransum fermentasi dengan jamur P. chrysosporium. Penelitian telah dilaksanakan dikadang penelitian selama 2 bulan, sedangkan ternak yang digunakan yaitu ternak kambing sebanyak 12 ekor dengan bobot berkisar 10-16 kg dan umur 8-12 bulan. Penelitian di rancang dengan dua perlakuan dan enam ulang dimana peneliti berupaya membandingkan antara perlakuan penggunaan isi rumen sapi tanpa fermentasi dan perlakuan isi rumen sapi fermentasi (P. chrysosporium). Setiap kandang penelitian dilengkapi tempat pakan dan air minum. Rancangan yang digunakan dalam penelitian ini adalah menggunakan uji homogenititas serta uji lanjutnya adalah Uji-t untuk membandingkan antara perlakuan dengan kontrol, mana yang paling baik. Fermentasi isi rumen sapi dengan jamur P. chrysosporium dapat memperbaiki kandungan nutrisi isi rumen sapi dibandingkan dengan isi rumen yang tidak difermentasi, sehingga ransum fermentasi memberikan hasil lebih baik terhadap pertumbuhan ternak kambing jantan..Kata kunci: Kambing Jantan, Phanerochaete chrysosporium, Pertumbuhan

Abstract

Purpose of the study: The aim of this study was to effect the warm water foot soak to decrease blood pressure in elderly at PSTW Gau Mabaji Gowa Regency. Methods: The design of this study was pre-experimental with the type of one-group t-test design in which the objective was to determine the effect of warm water foot baths on the decrease of hypertension in elderly in PSTW Gau Mabaji Gowa District. The sample size in this study are 10 respondents who match the inclusion criteria. Data collection is done by observation. In this research use paired sample t-test. at significance level ? = 0.05. Results: The results of the study showed that there was a warm water foot effect on blood pressure drop in elderly people at PSTW Gau Mabaji Gowa District (p = 0.000). Discussion: Blood pressure is 120-140 mmHg systolic pressure and 80-90 mmHg diastolic pressure. Seseornag expressed hypertension when blood pressure> 140/90 mmHg. Conclusion: there is influence of warm water foot soak to decrease of hypertension in elderly in PSTW Gau Mabaji Gowa Regency. Suggestion: The results of this research can be used as input for all parties, especially nurses who work in PSTW Gau Mabaji Gowa Regency in applying the implementation of warm water foot therapy in patients with hypertensive disorders
