Nanlohyhynanlohy@gmail.com<em>The limited availability of diesel oil encourages efforts to find new energy sources as alternative diesel fuels. Biodiesel can be extracted from various agricultural products, for example, coconut oil. As a tropical country, Indonesia is a very effective and potential country as a coconut producer. Vegetable oil has a higher viscosity than diesel oil. Compose bio-oils with various fuels additive is the way to reduce viscosity values, among others, by combining nanocarbon and metal catalysts. This study goals to know the characteristics of burning coconut oil as an alternative fuel with the addition of eucalyptus oil; and how long the combustion process takes from the starting point to the end. The results showed that adding eucalyptus oil to coconut oil can reduce the weakening of the carbon chain and increase the combustion temperature. The combustion efficiency of this coconut oil mixture varies depending on the amount of eucalyptus oil added, resulting in faster fuel combustion and a more powerful explosion. The color of the fire is an essential factor in ensuring that this mixture can be used safely and efficiently.</em>2024-07-31T00:00:00+00:00Copyright (c) 2024 Jurnal Rekayasa Material, Manufaktur dan Energihttps://jurnal.umsu.ac.id/index.php/RMME/article/view/18607Karakteristik Sifat Fisis Keramik Berpori Menggunakan Bahan Dasar Cangkang Kepah2024-03-05T14:22:44+00:00Gita Aulia Safira Widarigitasafira89@gmail.comEty Jumiatigitasafira89@gmail.comMasthura .gitasafira89@gmail.com<p><em>Research has been carried out which aims to determine the characteristics of porous ceramics with a mixture of Kepah clam shell powder and clay that can be produced and to determine the influence of Kepah clam shells and clay on the characteristics of porous ceramics, as well as knowing the variations in the composition of mixing Kepah clam shell powder and clay to obtain porous ceramics with optimum characteristics. The kepah clam shell material used is kepah clam shell waste that is no longer used. Variations in the mixture of clay, kepah clam shell powder and kaolin include 6 g : 2 g : 2 g, 5.5 g : 2.5 g : 2 g, 5 g : 3 g : 2 g, 4 g : 4 g : 2 g . The test parameters used are density, porosity and absorbability. The test results showed that the density value of sample A was 0.94 g/cm3, sample B was 0.92 g/cm3, sample C was 0.82 g/cm3 and sample D was 0.81 g/cm3. The porosity value in sample A is 14.32%, sample B is 14.64%, sample C is 17.6%, and sample D is 17.95%. The water absorption value in sample A is 17.38%, sample B is 17.77%, sample C is 17.38%, and sample D is 19.16%, reaching the standard value set by SNI 8640:2018, namely the maximum value. 25%.</em></p>2024-03-05T14:22:43+00:00Copyright (c) 2024 Jurnal Rekayasa Material, Manufaktur dan Energi
