Abstract

Oil and fat can be changed to become rancid. Rancidity of oils and fats may be caused by oxidative rancidity, enzymatic rancidity and hydrolytic rancidity. The most common rancidity o..f oils and fats are caused by atmosphere air oxidation. The damaged oils and fats which highly heat are caused by oxidation and polimerization process. Oxidation of oils and fats will result : aldehide compound, ketone, hydrocarbon, alcohol, lactone and aromatc compound which have rancid odor and bitter flavour. The factors which can accelerate the oxidation are radiation (heat and light), oxidizing agent, metal catalist andorganic catalist "Which is heat labile.

Abstract

In Indonesia, pesticide formulation mostly used is Emulsifiable Concentrate (EC). In order to get a suitable formulation in application, effective in use, stable in certain period of time and economically, stabilization of emulsion become an important thing. The stabilization is influenced specially by variety and optimum amount of emul­ sifier used. The Industry has been interested in emulsions stabilized by blends of anio­nic and nonionic emulsifier.

Abstract

Vanadium doped and bamboo activated carbon coated lithium iron phosphate (LiFePO4) used for lithium ion battery cathode has been successfully prepared. Lithium iron phosphate was prepared through a wet chemical method followed by a hydrothermal process from the starting materials of LiOH, NH4H2PO4, and FeSO4.7H2O. The dopant variations of 0 wt.%, 3 wt.%, 5 wt.%, and 7 wt.% of vanadium and a fixed 3 wt.% of bamboo activated carbon were carried out via a solid-state reaction process each by using NH4VO3 as a source of vanadium and carbon pyrolyzed from bamboo tree, respectively. The characterization was carried out using X-ray Diffraction (XRD) for the phase formed and its crystal structure, Scanning Electron Microscope (SEM) for the surface morphology, Electrochemical Impedance Spectroscopy (EIS) for the conductivity, and battery analyzer for the performance of lithium ion battery cathode. The XRD results show that the phase formed has an olivine based structure with an orthorhombic space group. Morphology examination revealed that the particle agglomeration decreased with the increasing level of vanadium concentrations. Conductivity test showed that the impedance of solid electrolyte interface decreased with the increase of vanadium concentration indicated by increasing conductivity of 1.25 x 10-5 S/cm, 2.02 x 10-5 S/cm, 4.37 x 10-5 S/cm, and 5.69 x 10-5 S/cm, each for 0 wt.%, 3 wt.%, 5 wt.%, and 7 wt.% vanadium, respectively. Vanadium doping and bamboo activated carbon coating are promising candidate for improving lithium ion battery cathode as the initial charge and discharge capacity at 0.5C for LiFePO4/C at 7 wt.% vanadium is in the range of 8.0 mAh/g.

Abstract

Limbah kulit durian merupakan salah satu bahan baku yang dapat diolah menjadi energi alternatif pengganti bahan bakar. Beberapa jenis limbah biomassa memiliki potensi yang cukup besar seperti limbah kayu, sekam padi, jerami, ampas tebu, cangkang sawit, dan sampah kota. Potensi lain yang belum tergarap adalah limbah kulit durian. Limbah-limbah tersebut apabila tidak dimanfaatkan akan menimbulkan bau yang tidak sedap dan dapat merusak ekosistem lingkungan. Penelitian ini bertujuan untuk melihat karakteristik pembakaran briket dari kulit durian berdasarkan nilai kalor dan uji nyala. Pembuatan briket ini menggunakan bahan perekat pati janeng sebanyak 1:2 dari berat briket, ukuran partikel briket adalah 80 mesh, bentuk briket lempeng dan silinder. Hasil penelitian menunjukkan bahwa briket yang dihasilkan telah memenuhi standar bahan bakar untuk rumah tangga. Nilai kalor yang dihasilkan oleh briket kulit durian adalah 5040 kal/gram, waktu yang dibutuhkan briket untuk menyala adalah 10 menit, dan lamanya nyala api pada briket adalah 55 menit tanpa menghasilkan asap diawal pembakaran. Briket yang paling baik dihasilkan adalah briket dengan ukuran 80 mesh berbentuk lempeng bulat dan nilai kalor 5040 kal/gram. Dapat disimpulkan bahwa briket yang dihasilkan dari limbah kulit durian dengan menggunakan pati janeng dapat digunakan sebagai bahan bakar alternatif yang ramah lingkungan.

Abstract

Saat ini nanopartikel magnetik dalam bentuk sistem core- shell banyak dikembangkan untuk mendapatkan nanopartikel dengan magnetisasi tinggi. Core berupa bahan logam transisi murni (Fe atau Co) dan shell berbentuk oksida maupun bahan anorganik/logam lain, diharapkan akan diperoleh nanopartikel yang tahan terhadap pengaruh oksidatif dengan permukaan yang siap untuk modifikasi lanjut. Pada penelitian ini, proses sintesis nanopartikel core-shell Fe/oksida Fe dilakukan dengan proses kimia presipitasi-reduksi maupun fisis dengan proses milling energi tinggi. Pada makalah ini dibahas struktur nanopartikel yang terbentuk dari kedua proses ini. Hasil pengamatan dengan Transmission Electron Microscope (TEM) menunjukkan struktur core- shell yang lebih jelas pada nanopartikel hasil proses kimia dibanding proses fisis.

Abstract

It's common that the waste water from electroplating industry contains heavy metals such as cyanide. Based on this research, reduction of cyanide content from electroplating waste water is conducted by CN and CNO oxidations with sodium hypochlorite as an oxidator. The result-of this research shown that the optimum condition for CN oxidations is on pH 10.5, reaction time 6 minutes which resulting CN reduction 98,6%, while the CNO oxidations is on pH 8. 0, reaction time 15 minutes. By process of oxidations, coagulations, sedimentations and filtrations the CN content from electroplating wastewater can be reduced from 3 0 mg!! to 0. 004 mg/! to fulfill waste water quality standard for electroplating industry maximum 0. 05 mg/!.
