Abstract

Research in the field of bioenergy technology is currently being developed. One of bioenergy types that became the focus of development in Indonesia is biohydrogen. In producing biohydrogen from palm oil mill effluent (POME) using inoculum from cow dung, the production of biomethane gas causes biohydrogen productivity being decreased. The method used to increase the productivity of biohydrogen in this study is by suppressing methanogenic microbial treatment method which is conducted by heating cow dung inoculum at 95 °C for 120 min. Producing biohydrogen was done by fermented both POME and cow dung inoculum in vial bottle 120 mL at room temperature. Fermentation condition was adjusted at pH 5.5 by phosphoric buffer 1 M. The results obtained in this study consist with the increasing value of biohydrogen productivity, maximum of cummulative biohydrogen production rate and yield were 75.61 % and 0.43 mL H2/hr and 104.82 mL H2/g COD, respectively. This method was also perfectly suppressed biomethane gas production with percentage decreasing value is 100 %. The aim of this study is to investigate the effectiveness of suppressing method in optimizing biohydrogen production.

Abstract

ABSTRAK   Industri elektroplatting merupakan penghasil limbah logam berat berbahaya, salah satunya kromium heksavalen. Kromium heksavalen merupakan logam yang berbahaya, mempunyai kadar racun yang tinggi dan bersifat karsinogenik penyebab kanker. Sehingga dilakukanlah upaya meminimalisasi limbah cair kromium dengan cara adsorpsi. Penelitian ini difokuskan pada pembuatan adsorben dari campuran tanin dan bentonit dengan perbandingan massa 1:3. Sampel yang digunakan adalah limbah cair sintetis dimana komposisi dari logam kromium heksavalen sesuai dengan limbah industri elektroplatting yaitu K2Cr2O7. Variabel yang digunakan adalah ukuran packing 1,0 cm dan 1,5 cm, dengan laju alir sebesar 180 ml/menit dan 240ml/menit sedangkan waktu kontak 20 menit hingga 100 menit. Pada hasil penelitian ini menunjukkan penyerapan krom tertinggi terjadi pada ukuran packing 1,5 cm dengan laju alir 240 ml/menit dan waktu kontak 20 menit yaitu 80,37%.   Kata Kunci : Elektroplatting, adsorpsi, kromium heksavalen

Abstract

Zeolite is a hydrated alumino-silicate compound having a main element which consists of alkali and alkaline-earth cations, especially Ca, K and Na, with a general formula (LmAlx Sig O2nH2O) where L is a metal. Zeolite can be synthesized from a sample containing silica and alumina. The compounds contain alkali hydroxide or organic bases. Palm kernel shells are one of the industrial wastes containing many minerals such as SiO2 58.02%; Al2O3 8.7%. The source of silica and alumina in oil palm shells is used as a base for making zeolites using the hydrothermal method in a reactor. Fine samples of palm shells were melted with NaOH at 500 °nn C for 1 hour and diluted to produce sodium silicate reactants. Making sodium aluminate reactant is done by dissolving NaOH in distilled water and then heating and adding Al(OH)3 to NaOH solution with stirring. Making zeolite is done by mixing sodium silicate and sodium aluminate reactants and the zeolite crystallization process is carried out using a hydrothermal reactor heated in the oven by varying the hydroternal temperature of 1200C, 150 ° C and 1800C for 8 hours. The synthesized zeolite was characterized using XRF, FTIR and SEM EDX.

Abstract

Biodiesel is an alternative fuel that can be renewed and as a promising of diesel fuel in the future.  In this study, the production of biodiesel from used waste vegetable oil through the initial treatment reaction saponification and without saponification. The process of producing of biodiesel can used by the transesterification method. The yield of biodiesel were obtained then analysis for quantity by calculating of the percent yield on each yield for biodiesel with saponification successively is 61.68%. The biodiesel product without saponification successively is 81.93%. The quality test produced for biodiesel density test with and without saponification is 0.8871 g / mL and 0.8975 g / mL ,% FFA 0.3375 mg KOH / g and 0.6325 mg KOH / g, and flash point 184 ? and 182.6 ?.
