The performance of hydrate was shown by the hydrate formation rate, the hydrate stability, and the storage capacity. In the study, we investigated the hydrate performance by influencing the rotation of crystallizer that predicted to increase the agitation of the hydrate performance. The hydrate represent the bond of water molecules and gas absorbed by the water molecules. In the experiment, we used the 50% propane and 50% butane as the gas absorbed. The gas was injected in a crystallizer at 3 bar pressure, then the crystallizer was rotated by 100, 200, and 300 rpm. The results shows that the best performances of hydrate when the crystallizer was rotated at 300 rpm. The crystallizer rotation speed of 300 rpm had the highest the formation rate and the decomposition rate. The highest decomposition rate indicated the highest stability. Meanwhile, the highest hydrate storage capacity was also occured at the rotation of 300 rpm as 2809 V / V.

Pengaruh Prosentase Minyak Goreng Bekas Terhadap Karakteristik Pembakaran Droplet Biodiesel Mega Nur Sasongko

Minyak goreng bekas merupakan kandidat yang baik sebagai bahan bakar pengganti mesin diesel. Ketersediannya yang melimpah karena merupakan sampah yang tidak terpakai dan sifat fisiknya yang mirip dengan minyak solar menjadikan minyak goreng bekas lebih dipilih sebagai biodiesel pengganti solar dibandingkan dengan jenis minyak nabati lainnya. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh prosentase campuran minyak goreng bekas dalam bahan bakar biodiesel terhadap karakteristik pembakaran droplet biodiesel yang meliputi visualisasi api, ignition delay dan burning rate pembakaran. dalam penelitian ini, campuran minyak goreng bekas yang telah diesterifikasi divariasikan dalam 0% sampai 100%. Hasil penelitian menunjukkan bahwa pada campuran biodiesel minyak goreng bekas dibawah 50%, semakin tinggi kandungan biodiesel dalam campuran solar semakin tinggi juga temperatur maksimum pembakaran droplet Sedangkan pada kandungan biodiesel minyak goreng diatas 50% sampai 100% menunjukkan temperatur yang cenderung konstan. Selain itu kecepatan pembakaran droplet akan semakin rendah seiring dengan peningkatan kandungan minyak goreng bekas dalam biodiesel. Semakin besar kandungan minyak goreng bekas dalam biodiesel menyebabkan tinggi api droplet menjadi lebih tinggi. Kandungan air dalam biodiesel minyak goreng bekas menyebabkan terjadinya microexplotion pada pembakaran droplet campuran biodiesel minyak goreng bekas dan solar

Thermoelectric technology works by converting thermal energy into electricity directly or preferably. Thermoelectric technology works by converting thermal energy into electricity directly or preferably. Theuse of thermoelectric as a cooler in cool box systems has been extensively studied. The thermoelectric cool ability can be achieved depending on the design of a good system. Therefore, this study aims to determine the performance of thermoelectric cooler cool box based on single and multi stage. Tests carried out using cool boxes of dimensions of 31 cm x 19 cm x 24 cm witha thickness of 3 cm and with the TEC1 12706 module. The voltage used in each configuration is 12 Volts. Temperature data readings on laptops using DAQNavi_SDK data logger connected to type K thermocouples. The result showed the multi stage configuration reached a room temperature of around 19.3 oC and 21.8 oC for single stage. Meanwhile, the multi stage configuration COP value is 1.36 and with a single stage configuration is0.88. It can be concluded that the thermoelectric configuration has an influence on the performance of the cool box system. Keywords: Cool box, Thermoelectric module, Multi stage, single stage, COP

Natural Surfactant from Fatty Acid of Morinda citrifolia L. for Deinking Flotation Trismawati Trismawati; I.N.G. Wardana; Nurkholis Hamidi; Mega Nur Sasongko

Natural surfactant is developed as fatty acid derivate from natural resources such as palm oil, sunflower oil, and safflower oil. In South East Asia countries, the palm oil is used as the main resources of fatty acid derivate. Seed oil of Morinda citrifolia L. contains unsaturated fatty acid. It is extracted and concentrated. The concentrated fatty acid of Morinda citrifolia L. (CFAMC) is used as deinking surfactant. The CFAMC is analyzed by GCMS for its constituent and its deinking flotation performance is evaluated for yield, brightness, and ERIC of deinked pulp. Based on the old newspaper (ONP) pulp with brightness of 35.84 °ISO, and ERIC of 1982.4 ppm, the deinking flotation performance of CFAMC is approaching the natural surfactant. The brightness increase is 11.36% and 16.35%, and the ERIC reduction is 37.40% and 47.73% for CFAMC and natural surfactant respectively. SEM analysis is provided to see the residual Nanoink particles on the fibers.
