Abstract

The traditional method of making salted eggs usually using the salting, which is done well, its needs time about 14 days. This condition indicated to have a method that can speed up the process of salting the eggs. The process of salting eggs normally uses the usual soaking method where the eggs are coated with bricks and rubbing ash then left to stand. The diffusion of salt penetration in traditional salting takes place slowly. For this reason, the speed of salt penetration can be done by increasing the salt level in the soaking solution so that the penetration of salt into the eggs can take place faster. This methodology in this research study using of air pressure to speed up the process of salting the eggs. The method used is to use air pressure with the use of compressor air pressure at a pressure of 4 - 6 Bar with a salting test time of about 4 to 7 hours

Abstract

The depletion of fossil fuel reserves and natural gas makes people rethink to find alternative energy substitutes. Biomass is an alternative energy that is still abundant and has not been fully utilized. Gasification is one of alternative in gas making that change from solid fuel (wood powder) to thermochemical flammable gas. The research used downdraft gasification with experimental wood powder. The implementation of research was done in workshop of Indramayu State of Polytechnic, using batch system, it means once the import of biomass in the furnace from the beginning until the biomass out by 5 kg of wood powder biomass. Equivalence Ratio (ER) performed 4 variations namely: 1.01; 1.13; 1.34; 1.52. The recorded data are: temperature inside reactor, gasification operation time, air intake, syngas content, and flame visualization. The results obtained from the gasification process showed if the Equivalence Ratio (ER) is higher so the heating value of syngas decrease. LHV at ER 1.52 of 3980,306 Kj / m3 and the synthetis gas content decreased as much as 21,7806 %

Abstract

Collision test is needed in transportation area in order to anticipate injuries of passangers when the accident occurred. Therefore, this test must be done for achieving standar requirements which is known by crashworthiness. This paper discussed about development of crasworthiness test by using modelling impact transferability by numerical simulation. The goal is to know the error of maximum deformation when given axial dynamic loading between numerical simulation and real experiment. Furthermore, analitic was used to validate duration of stress wave propagation from result of numerical simulation. This simulation used explicit finite element method by using PAM-Crash. The component of this research was impactor and impact of transferability with 80 and 27 kg of mass. The square tube-thin walled structure with holes as crush initator 3 mm of diameter was used as specimen. The result shows maximum deformation and duration of stress propagation error which are 3.90 % and 14.89 %.

Abstract

The biomass gasification process is a way to obtain combustible syn-gas through combustion of biomass in a closed reactor with the help of air from a compressed blower. Without the help of air gas formation process is not possible, the combustion in the furnace must have air that can start a fire. The tool for supplying air is a pressure blower. The purpose of this study was to obtain a stoichiometric air and biomass mixture in the rice husk gasification process. With the stoichiometric air fuel ratio (AFR) in the rice husk gasification process, it will produce a perfect flammable syn-gas.The method used in this research is to change the rice husk solid through the gasification process. The gas released in the gasification process will be varied at the blower speed with or without using a dimmer. From the test results, it can be seen in the syn-gas output from the reactor. on dimmer 1 the inlet airspeed is 3.5 m / s, on dimmer 2 the airspeed is 4.0 m / s. In dimmer 3 the air velocity is 4.5 m / s and in dimmer 4 the air velocity produced is 5.0 m / s From the results of testing the air velocity of each variation that enters the reactor only air velocity 4.5 m / s and 5.0 m / s or in dimmers 3 and 4 which can produce flammable syn-gas.

Abstract

Valve (katup) sebagai salah satu produk industri, sangat dibutuhkan oleh perusahaan yang bergerak mengontrol aliran cairan untuk efisiensi. Kebutuhan tentang ini banyak digunakan oleh perusahaan makanan, obat-obatan, minuman, pembangkit listrik dan industri minyak dan gas. Tujuan penggunaan valve adalah untuk membatasi dan mengontrol cairan pada kondisi tekanan tinggi. Salah satu katup yang sering digunakan adalah ball valve, yaitu katup dengan tipe gerak memutar. Adanya permintaan ball valve ini, dibutuhkan produk dengan spesifikasi tertentu memiliki rancangan dengan tingkat kekuatan yang baik. Dengan kata lain, produk valve (katup) yang baik, harus memiliki kekuatan yang baik, aman dan sesuai dengan kebutuhan dilakukan pengujian. Penelitian ini bertujuan untuk melakukan analisis terhadap ball valve 4 inch ANSI 300 untuk memastikan katup yang diproduksi sesuai spesifikasi, kuat dan tahan terhadap tekanan fluida. Metode yang digunakan adalah Finite Element Analysis (FEA) dengan software Solidworks. Analisis dilakukan pada ball valve 4 inch ANSI 300 dengan keadaan full open, hall open dan full closed serta dengan pembebanan 725 psi dan 1087.5 psi hasil dari Computational Fluid Dynamics (CFD). Analisis dilakukan pada temperatur -29.50C, 250C dan 4250C. Berdasarkan hasil analisis dengan FEA, dinyatakan bahwa ball valve 4 inch ANSI 300 kuat dan aman untuk digunakan. Nilai faktor keamanan (safety factor), signifikan lebih tinggi dari nilai safety factor minimum yang diizinkan.

Abstract

Salah satu metode untuk pengawetan ikan adalah dengan proses pengeringan. Proses pengeringan ikan yang dilakukan oleh nelayan khususnya di Desa Eretan Wetan, Kecamatan Kandanghaur, Kabupaten Indramayu masih secara tradisional. Dari segi waktu dan kualitas, metode ini tidak efisien dan efektif, karena panas matahari tidak stabil. Sehingga kadar air untuk produk ikan kering yang dihasilkan masih jauh dari standar pangan yang telah ditentukan. Untuk itu, penelitian ini bertujuan untuk menganalisis alat pengering ikan dengan teknologi matahari dan biomassa. Pengeringan ikan dengan sumber tenaga surya dan ditambahkan dengan panas yang berasal dari pembakaran briket yang ditempatkan secara proposional. Rak pengeringan ikan di dalam ruang kaca, bergerakmemutar searah sumbu Y dengan kecepatan maksimum 20-25 rpm, agar pemanasan stabil ke segala arah. Penelitian ini, menganalisis kekuatan dan safety factor dua rangka utama alat pengering ikan, yaitu rangka bawah dan rangka atas karena menampung beban keseluruhan ± 30 kg. Metode analisis ini menggunakan Finite Element Analysis (FEA) dengan bantuan software Solidworks. Berdasarkan hasil analisis kekuatan dengan FEA, disimpulkan bahwa pengering dengan kapasitas daya tampung ikan ± 5 kg kuat dan relatif aman. Tegangan maksimum untuk rangka bawah dan rangka atas adalah 2,03e+007 N/mm2 dan 3,14e+006 N/mm2. Perubahan bentuk (displacement) dan regangan (strain) tidak signifikan dengan rata-rata 0,18 mm. Sedangkan nilai safety factor menunjukkan nilai 7,34 dan 1,5 dan masuk kategori aman.
