PEMANFAATAN BERBAGAI JENIS KULIT PISANG SEBAGAI BAHAN PEMBUATAN BIOETANOL MENGGUNAKAN RAGI TAPE
No full textAbstrak- Pisang merupakan salah satu kebutuhan pokok masyarakat Indonesia yang diproduksi dengan
berlimpah. Kulit pisang memiliki nilai ekonomis yang rendah karena tidak digunakan dan dibuang begitu
saja sehingga menjadi limbah. Kandungan yang terdapat dalam kulit pisang diantaranya vitamin (B dan
C), air, protein, karbohidrat, lemak, kalium, zat besi dan lignoselulosa yang cukup tinggi dan dapat
didegradasi menjadi bentuk yang lebih sederhana yaitu glukosa yang bisa dimanfaatkan sebagai bahan
dasar bioetanol. Penelitian ini bertujuan untuk mengetahui pengaruh jenis kulit pisang, konsentrasi
NaOH dan massa kulit pisang terhadap produk bioetanol yang menggunakan ragi tape. Kulit pisang
yang digunakan adalah kulit pisang ambon, awa, kapas, mauli, talas dan susu. Metode yang digunakan
pada penelitian adalah pretreatment menggunakan H2SO4 1% dan NaOH (4-14%), hidrolisis enzimatik
menggunakan enzim selulase serta larutan buffer dan fermentasi menggunakan ragi tape dan nutrient.
Larutan bioetanol hasil fermentasi disaring dan diambil cairannya yang kemudian dianalisa dengan alat
Gas Chromatograph. Dari hasil penelitian dapat disimpulkan kadar bioetanol tertinggi yang dihasilkan
pada jenis kulit pisang yaitu kulit pisang mauli sebesar 0,053% dan yang terendah pada pisang ambon
sebesar 0,00021%. Kadar bioetanol tertinggi dihasilkan pada pisang talas dengan konsentrasi NaOH
14% sebesar 0,133% dan yang terendah pada NaOH 4% sebesar 0,029%. Kadar bioetanol tertinggi
dihasilkan pada pisang talas dengan massa kulit pisang 30 g sebesar 0,305% dan yang terendah pada
massa kulit pisang 2 gr sebesar 0,029%. Dapat dilihat bahwa semakin tinggi kadar karbohidrat yang
terdapat pada kulit pisang maka semakin tinggi juga kadar bioetanol yang didapat.

Abstrack- Banana is the one of main consumption that produced so much in Indonesia. Banana’s peel
has a low economic value because it is not used and usually just thrown away and then its can becomes to
waste. Compositions of banana’s peel are B & C vitamins, water, protein, carbohydrates, fat, potassium,
iron and lignocellulose is high and can be degraded into simpler forms that is glucose can be used as the
basic material of bioethanol. Purpose of this experiment are to understanding the influence of the
banana’s peel, the mass concentration of NaOH and then mass of banana’s peel toward bioethanol
products with used yeast. Banana’s peel which used in the experiment were ambon, awa, kapas, mauli,
talas and susu. The methods were used in this experiment was pretreatment 1% of H2SO4 and NaOH (4-
14%), hydrolysis of enzimatic used a cellulase enzyme and buffer solution and also fermented used yeast
and nutrient. Then bioethanol was filtered and taken to analyzed by Gas Chromatograph. The results of
this experiment can concluded that the highest levels of bioethanol produced in banana’s peel is mauli
which produced bioethanol at a concentration of 0.053% and the lowest in ambon at a concentration of
0.00021%. The highest levels of bioethanol produced in talas at treatment with NaOH 14% was 0.133%
and the lowest at NaOH 4 % at 0.029%. The highest levels of bioethanol produced on 30 gram of mass of
talas’s peel was 0.305% and the lowest on 2 gram of mass of talas’s peel was 0.029%. It can be seen that
the higher concentrations or levels of bioethanol also toward the carbohydrate concentrations of
banana’s peel.

Heavy metal contents and magnetic properties of surface sediments in volcanic and tropical environment from Brantas River, Jawa Timur Province, Indonesia
No full textBrantas river is a largest urban river upplying raw water and drainage in Jawa Timur Province,
Indonesia. Dense population along the river is a threat of pollution due to anthropogenic pollutants.
In this study, we characterize the magnetic properties and heavy metal contents of surface sediments
in various locations along the Brantas river. This study aims to enhance our understanding of the
relationship between magnetic parameters and heavy metal contents in surface sediments from
river. Surface sediment samples were taken and measured by a series of magnetic measurements,
mineralogical analysis and heavy metal contents. The results show that magnetic minerals in surface
sediments of Brantas river are dominated by PSD magnetite mineral. This relatively coarser grain
size can be caused by magnetic particles produced by erosion around the river. Surface sediments
have very high mass-specific magnetic susceptibility varying from 844.0 to 7231.4 × 10-8 m3kg-1
(on average of 3022.9 × 10-8 m3kg-1) because influenced by the surrounding volcanic
environment. Based on the pearson correlation analysis, magnetic susceptibility has strong positive
correlation with the heavy metal contents of ferromagnetic elements such as Fe and Co so that it can
potentially be used as an indicator of pollution of both these heavy metals in the Brantas river. This
present work shows the novelty of the relationship between magnetic susceptibility and heavy metal
contents in surface sediments from river in volcanic and tropical environment.

BIO-CYCLE FARMING SYSTEMS ON SUB-OPTIMUM LANDS: OPTIMIZING INTERNAL NUTRIENT FLOWS IN AGRICULTURAL-ECOLOGICAL SYSTEMS ON THE TIDAL LOWLAND
No full textThe strategy of sub-optimum land uses including tidal swamp lands through a commodity based approach is difficult to be implemented instead of an agricultural-ecosystem based approach. In line with that is a strategy of fertilization also has to refer to the agricultural ecosystem based approach. To formulate the strategy of fertilization in the tidal swamp land it is necessary to carry out an observation of nutrient flow potentials in the agricultural ecosystem. This preliminary study was limited to the observation of N flows at a farm scale agroaquaculture system in the tidal swamp land during rainy season at November 2011 - January 2012. The total N capacity of the system reached 167 kg ha-1. In the amount of 84 kg ha-1 of the total capacity was available for biomass production in the system, coming from river water,fishpond muds, and rainwater successively 55, 16, and 13 kg N ha-1. Optimizing N flows of the system related to the fertilization strategy could be reached through the development of farm lands into an agro-aquaculture system. With the ratio of land area of raised beds and fishpond of 3:7, the system supplies 31.5 and 36.7 kg N ha-1 in order to produce biomass on raised beds and fishpond respectively
One-pot Selective Conversion of Biomass-derived Furfural into Cyclopentanone/Cyclopentanol over TiO2 supported bimetallic Ni-M (M = Co, Fe) Catalysts
No full textOne-pot selective conversion of biomass-derived furfural (FFald) into cyclopentanone (CPO) or cyclopentanol (CPL) using bimetallic nickel-based supported on TiO2 (denoted as Ni-M(3.0)/TiO2; M = Co and Fe; 3.0 is Ni/M molar ratio) have been investigated. Catalysts were synthesized via a hydrothermal method at 150⁰C for 24 h, followed by H2 reduction at 450⁰C for 1.5 h. X-ray diffraction analysis (XRD) showed that the formation of Ni-Co alloy phase at 2θ = 44.2⁰ for Ni-Co(3.0)/TiO2 and Ni-Fe alloy at 2θ = 44.1⁰ for Ni-Fe(3.0)/TiO2. The amount of acid sites was measured by using ammonia-temperature programmed desorption (NH3-TPD). Ni-Co(3.0)/TiO2 has three NH3 desorption peaks at 180⁰C, 353⁰C, and 569⁰C with acid site amounts of 1.30 μmolg1, 1.0 μmolg1, and 2.0 μmolg1, respectively. On the other hand, Ni-Fe(3.0)/TiO2 consisted of NH3 desorption peaks at 214⁰C and 626⁰C with acid site amounts of 3.3 μmolg1 and 2.0 μmolg1, respectively. Both Ni-Co(3.0)/TiO2 and Ni-Fe(3.0)/TiO2 catalysts were found to be active for the selective hydrogenation of FFald to furfuryl alcohol (FFalc) at low temperature of 110⁰C, H2 3.0 MPa, 3 h with FFalc selectivity of 81.1% and 82.9%, respectively. High yields of CPO (27.2%) and CPL (41.0%) were achieved upon Ni-Fe(3.0)/TiO2 when the reaction temperature was increased to 170⁰C, 3.0 MPa of H2, and a reaction time of 6 h. The yield of CPO+CPL on the reused catalyst decreased slightly after the second reaction run, but the activity was maintained for at least three consecutive runs.
