Abstract

Distribusi panas horisontal seperti halnya perambatan panas pada pelat homogen merupakan rambatan panas yang merambat secara konduksi . Panas yang dialirkan pada bagian pelat homogen akan merambat dan terdistibusi dengan sendirinya sehingga temperatur dalam bagian pelat akan mencapai disribusi suhu yang konstan pada waktu t. Dalam penelitian ini telah dimodelkan distribusi panas horisontal pada waktu steadystate (keadaan tunak) semisal pada bahan berbentuk pelat homogen  dan mensimulasikan pendistribusian kesetimbangan temperatur dalam pelat homogen.Metode penelitian ini menggunakan metode purata diskrit dengan bahasa pemrograman Java. Hasil penelitian menunjukkan bahwa metode purata diskrit dapat dibuat sebagai pemodelan konduksi panas pada pelat homogen dengan hasil numerik yang sangat mendekati nilai eksaknya. Sedangkan hasil simulasi pendistribusian temperatur dengan 9, 16 dan 49 interior mest point (IMP) menunjukkan bahwa nilai temperatur yang terdapat di tengah-tengah merupakan nilai rata-rata dari titik temperatur yang ada di sekelilingnya. Kata kunci: Distribusi Temperatur, Metode Purata Diskrit, Interior Mest Point (IMP).

Abstract

A polymer matrix composite has been made to strengthen green mussel shell particles (Perna Viridis L.) as an effort to utilize the potential of green mussel waste for polymer composite filler material. The purpose of this study was to determine the effect of the volume fraction of the green mussel shell particles on the mechanical properties of polymer matrix composites. The mechanical properties tested are the tensile strength and impact strength of the Polymer Matrix Composite material. The matrix material used in this research is polyester Yucalak157 @ BQTN-EX with Methyl Ethyl Keton Peroxide as catalyst and filler material in the form of 100 mesh green mussel shell particles with a variation of the filler volume fraction of 10%, 20%, 30% and 40%. This composite manufacturing method is to use the hand lay up method. The results of this study, obtained tensile strength values between 32.81-39.77 MPa where the highest tensile strength was found in specimens with a filler volume fraction of 40% and the lowest in specimens with a filler volume fraction of 10%; and impact strength (ductility) between 0.190-0.317 J / mm2 where the highest impact value was found in the test sample with a filler volume fraction of 10% and the lowest was in the specimen with a filler volume fraction of 40%. The increase in tensile strength value is influenced by the addition of a larger filler composition. On the other hand, the durability / impact price decreases with the increase in filler given. Based on microstructural observations, the greater the filler composition added to the matrix can reduce the size of the voids formed in the composites that have been made, it can be interpreted that the distribution of fillers is more evenly distributed.

Abstract

The increasing number of traditional boats made from wood can cause the forest to be deforested. Besides, it also results in scarcity and an increase in the price of basic wood materials so that production costs are increasingly expensive—also, the factors of decay by mould, heating, weathering. One of the efforts that can be made in the traditional shipbuilding process is through making boats made from cheap and high-quality E-Glass fibre laminate composite boards. The purpose of this study was to determine the effect of volume composition of E-glass fibres and scallop shell particles on the tensile strength of hybrid composites. Making hybrid composites by mixing scallop shell filler, E-Glass fibre and matrix. Percentage volume fraction 0C: 0E, 10C: 20E, 15C: 15E and 20C: 10E. The results showed that the maximum tensile strength at the volume fraction of 10C: 20E was 34.15567 MPa, this result was higher than the maximum requirements set by BSN in 2006, namely 0.304 MPa. The existence of a strong bond between the fibres and the matrix can increase the tensile strength of the composite as well as the influence of the scallop shell particles which can help the matrix to accept external loads/stresses so that the composite strength increases.
