Abstract

Industry 4.0 era materials used by entrepreneurs should be recycled, environmentally friendly, renewable with less chemical content. Indonesia as a tropical country has a large land area with the potential to produce the largest natural fiber in the world. One opportunity that can be applied to the utilization of natural fibers in air filters that currently use dominant materials is synthetic fibers. natural fiber has the advantage because it does not contain toxic chemicals, local raw materials, and is easily produced. This research will analyze the mechanical and morphological characteristics of biological fibers that have great potential as pre-filter raw material. Analysis of mechanical properties through tensile strength testing for single fibers and morphological analysis through scanning electron microscopy (SEM). Tensile testing was the results are; palm oil has a tensile strength of 620 MPa; 998 MPa and 213 MPa flax coconut fiber. For the morphological test results from SEM analysis for ramie fiber, it looks solid without fiber holes; The fibers appear to be many small fibers bound to one another while coir fibers have many pore holes in one observed fiber.

Abstract

Abstrak Terkait perkembangan energi dunia saat ini, tidak lepas dari peran pembangkit listrik, baik itu pembangkit konvensional maupun terbarukan. Pada dunia industri yang semakin maju dan mengarah ke persaingan global, maka perusahaan secara berkelanjutan perlu diminimalisir kerusakan pada mesin selama kegiatan produksi, melalui perbaikan dan perawatan. Turbin uap termasuk mesin penggerak, dengan energi fluida kerja dipergunakan langsung untuk memutar sudu turbin. Pada aliran fluida memberikan pengaruh pada daya dan efisiensi turbin uap. Pemanfaatan turbin uap banyak digunakan dalam berbagai industri. Penelitian ini bertujuan untuk mengetahui pengaruh dari laju uap terhadap efisiensi turbin berdasarkan data aktual maupun data desain. Pengambilan data dilakukan menggunakan metode observasi di PT. XXX pada pembangkit listrik tenaga uap. Analisis nilai efisiensi turbin berdasarkan nilai laju uap dan beberapa variable uap lain yang masuk dan keluar turbin terkait daya generator serta daya kerja turbin. Efisiensi dapat juga dihitung dengan membandingkan daya output dan input yang dihasilkan turbin. Berdasarkan analisis diperoleh bahwa data dari laju uap, daya aktual, kerja, dan heat rate turbin diperoleh hasil nilai efisiensi tertinggi sebesar 90,5% dan terendah 56,1%. Berdasarkan hasil analisa data penelitian yang telah dilakukan bahwa kenaikan dan penurunan efisiensi turbin uap dipengaruhi aliran massa uap selain itu juga oleh faktor : tekanan, temperatur dan entalpi.

Abstract

Ceramics are widely used by people in industries for various purposes, for example to make cups and tiles. Currently ceramics are widely used in various industrial raw materials. Ceramics are used as materials for making spark plugs, electrical insulators, and raw materials for printing tools. The ceramics industry is energy intensive in utilizing electrical energy. The amount of energy absorption affects the amount of costs that must be incurred by companies for energy consumption. To reduce costs used by ceramic companies during production, the use of energy is a way to increase the efficiency of the tunnel kiln. Therefore, based on these problems, research was carried out to analyze the data resulting from measurements of the large flow rate of heat transfer by conduction in the thickness of the wall, the amount of heat loss lost by convection on the outside of the wall, and the amount of loss in production costs incurred due to heat loss. This aims to obtain a solution that saves electrical energy used in the production of ceramics. So it was obtained that the highest conduction was in the top firing zone of the core from burning red bricks with heat dissipation reaching 829.73 Watts. Meanwhile, the heat lost at a distance of 50 cm and at a distance of 100 cm is the top firing zone which has the greatest heat loss of up to 0.1 MW compared to the other zones. The preheating zone reaches 5 kW and the cooling zone reaches 16 kW.
