Published: November 2019

Furfural adalah salah satu bahan kimia penting yang dapat diubah menjadi berbagai bahan kimia seperti furfuryl alkohol dan asam levulinat. Furfural dapat diproduksi dari biomassa lignoselulosa dalam kondisi asam dengan mengkonversikan fraksi hemiselulosa dalam biomassa menjadi gula pentosa dan selanjutnya menjadi furfural. Reaksi degradasi furfural tidak diinginkan karena dapat mengurangi hasil furfural yang telah dihasilkan. Tujuan dari penelitian ini adalah untuk menghitung parameter kinetika dari reaksi degradasi furfural menggunakan metode numerik dan integral. Hasil penelitian menunjukkan bahwa nilai konstanta laju reaksi dan energi aktivasi dari perhitungan metode numerik dan integral berbeda karena perbedaan dalam metode perhitungan. Pada metode integral, reaksi degradasi furfural pada suhu yang lebih tinggi (170oC) sesuai dengan model orde nol karena sebagian besar furfural telah terdegradasi dalam reaksi, akan tetapi reaksi degradasi furfural pada suhu yang lebih rendah (150oC dan 160oC) sesuai dengan model non-second order.

Furfural is one of the important building block chemicals that can be converted into various chemicals such as furfuryl alcohol and levulinic acid. Furfural can be produced from lignocellulosic biomass in acidic condition which hemicellulose fraction in biomass can be converted into pentose sugar and subsequently became furfural. Furfural degradation reaction is not desirable because it can reduce the yield of furfural that had been produced. The purpose of this study was to calculated kinetic parameters of furfural degradation reaction using numerical and integral methods. The results showed that the value of reaction rate constants and activation energies from numerical and integral methods calculation were different due to the differences in calculation methods. Using integral method, reaction order of furfural degradation at higher temperature (170oC) follows zero order because most of the furfural had been degraded in the reaction, but reaction order of furfural degradation at lower temperature (150oC and 160oC) follows non-second order.

Published: November 2019

Sabut kelapa adalah salah satu limbah lignoselulosa yang dapat dikonversikan menjadi bioetanol. Konversi bioetanol pada penelitian ini dilakukan melalui beberapa tahapan yaitu proses pre-treatment, proses Saccharification and Simultaneous Fermentation (SSF), dan proses pemurnian. Proses pre-treatment sebagai proses pemecahan ikatan lignoselulosa menjadi poin utama dalam proses konversi biomassa lignoselulosa. Penelitian ini dilakukan untuk mengetahui pengaruh iradiasi gamma terhadap pemecahan ikatan lignoselulosa pada proses pre-treatment tersebut. Proses iradiasi gamma divariasikan pada dosis sebesar 0 kGy, 100 kGy, 150 kGy, 200 kGy, 250 kGy dan dilanjutkan pre-treatment secara kimia menggunakan NaOH 4%. Kemudian dilanjutkan proses pemurnian setelah proses SSF selama 72 jam. Kadar bioetanol yang diperoleh setelah proses pemurnian diukur menggunakan metode refraktometri dan piknometri. Pada penelitian ini diperoleh kadar bioetanol tertinggi pada dosis iradiasi gamma 200 kGy, yaitu 35,15% untuk metode refraktometri, dan 36,77% untuk metode piknometri. Hasil tersebut jauh lebih tinggi bila dibandingkan dengan kadar bioetanol tanpa iradiasi gamma yaitu 2,45% untuk metode refraktometri, dan 6,92% untuk metode piknometri. Penelitian ini menunjukkan bahwa metode pre-treatment dengan iradiasi gamma dapat menghasilkan kadar bioetanol yang lebih tinggi dibandingkan tanpa menggunakan iradiasi gamma.
Coconut husk is one of lignocellulosic wastes that can be converted into bioethanol. Bioethanol conversion in this study was carried out through several stages, namely the pre-treatment process, the Saccharification and Simultaneous Fermentation (SSF) process, and the purification process. The pre-treatment process as the process of breaking lignocellulosic bonds becomes the main point in the process of lignocellulosic biomass conversion. This research was conducted to determine the effect of gamma irradiation to breaking lignocellulosic bonds on the pre-treatment process. Gamma irradiation process was varied in doses of 0 kGy, 100 kGy, 150 kGy, 200 kGy, 250 kGy and continued with chemical pre-treatment using 4% NaOH. Then the purification process was continued after the SSF process for 6 days. Bioethanol levels obtained after the purification process were measured using refractometry and picnometry methods. In this study, the highest levels of bioethanol were obtained at a gamma irradiation dose of 200 kGy, namely 34.93% for the refractometry method, and 26.67% for the picnometry method, respectively. These results are much higher when compared to bioethanol levels without gamma irradiation, which is 2.25% for the refractometry method, and 5.49% for the picnometry method, respectively. This study shows that the pre-treatment method with gamma irradiation can produce higher levels of bioethanol than without using gamma irradiation.

Published: November 2019

Parameter interaksi biner kesetimbangan uap-cair campuran yang melibatkan alkohol rantai bercabang atau aseton telah ditentukan pada penelitian ini. Data kesetimbangan uap-cair kondisi isobarik pada tekanan atmosferik telah dipilih total sebanyak 14 sistem. Data kesetimbangan tersebut kemudian dikorelasikan dengan model koefisien aktifitas Wilson, Non Random Two-Liquid (NRTL) dan Universal Quasi-Chemical (UNIQUAC) untuk diperoleh parameter interaksi binernya. Parameter tersebut ditentukan sebagai fungsi suhu pada penelitian ini untuk meningkatkan kemampuannya dalam aplikasi pada kisaran suhu yang panjang. Korelasi menunjukkan hasil yang baik dikarenakan root mean square deviation (RMSD) antara data eksperimental dengan hasil perhitungan relatif kecil. Sebagai tambahan, perilaku masing-masing sistem biner tersebut juga diamati pada kesempatan ini. Parameter yang diperoleh dapat digunakan untuk optimasi desain kolom distilasi pada proses pemurnian produksi bioetanol.

The binary interaction parameters of vapor-liquid equilibrium for the mixtures involving branched-chain higher alcohols or acetone have been determined in this study. Isobaric vapor-liquid equilibrium data at atmospheric pressure have been selected for a total of 14 systems. The VLE data were then correlated with the Wilson, NonRandom Two-Liquid (NRTL) and Universal Quasi Chemical (UNIQUAC) activity coefficient models to obtain its binary interaction parameters. The parameters were determined as the temperature-dependent in this study to increase its ability in wide temperature range applications. The correlations showed good results because the root mean square deviation (RMSD) between the experimental data and calculation values were relatively low. In addition, the behavior of each binary systems were also observed in this study. The obtained parameters could be used to optimize the distillation column design in the purification process of bioethanol production.
Données expérimentales préliminaires sur la stabilité de la rhönite à 1 atmosphère. Application aux gisements naturels
Authors: Boivin Pierre 
Published: November 2019

An experimental study under 1 bar pressure with ƒO₂ monitoring has been performed on rhönite-bearing basanitoïde, hawaiite and pure kaersutite from the alkalibasalt series of the Devès (French Massif Central). The following assemblages are recorded to lower temperatures :
-NNO buffer
(1) Kaersutite ol + (sp) + plag + rhönite + cpx + mt + liq
(2) Basanitoïde ol + (sp) + cpx + mt + plag + rhönite + liq
(3) Hawaiite ol + (sp) + plag + cpx + mt + liq
-IW buffer
(4) Kaersutite ol + (sp) + cpx + plag + rhönite + liq
(5) Basanitoïde ol + cpx + plag + rhönite + liq
(6) Hawaiite ol + cpx + plag + liq
Spinel reacts with liquid to give plagioclase (cases 1, 3 and 4) and magnetite (cases 2 and 3).
The liquidus temperatures of the kaersutite (1310 °C) and the basanitoïde (1 300 °C) do not vary significantly with ƒO₂ contrary to the liquidus temperature of the hawaïte : 1 195 °C for NNO and 1 255 °C for IW.
The crystallization course for the basanitoïde shows spinel and clinopyroxene may coexist (at equilibrium) under 1 bar. The temperature of crystallization of rhönite is independent of the ƒO₂ between NNO and IW buffers and it seems rather controlled by the bulk composition of the sample : 1 170 °C for the kaersutite versus 1 100 °C for the basanitoïde.
This petrographic study and experimental results together with available and petrographic data dealing with rhönite-bearing and melilite-free lavas suggest that the crystallization of rhönite and its coexistence with plagioclase is controlled by the rock bulk composition (chiefly Ti and Ca) and by early crystallization and Ti content of clinopyroxene depending on pressure.

Authors: Williams Sydney A. , Duggan Marjorie 
Published: November 2019

This mineral was recently found on already ancient dioptase specimens (about 1940) from Tiger, Arizona ; it could very well have been mistaken for mimetite. The color is orange cadmium (RHS 23 A) and the powder pale orange ; hardness (Mohs) 3.5 ; measured density 5.49, calculated density 5.58 g/cm3. Crystals can reach 1 mm long in size with a good cleavage on {100}. Optically biaxial negative with 2V = 85°, α = 2.28, β = 2.31 and γ = 2.34 ; γ is along the b axis and the extinction angle is : cΛX = + 36°.
Wet chemical analysis gave : PbO 67.6, CuO 7.8, CrO₃ 10.5, SiO₂ 4.9, H₂O 7.3, sum 98.1 % ; this corresponds to the formula Pb₃Cu(CrO₄)SiO₃(OH)₄•2 H₂O.
Macquartite is monoclinic, probably C2/m, with a = 20.81, b = 5.84, c = 9.26 Å and P = 91°48' ;Z = 4. The strongest lines in the X-ray powder pattern are : 4.822 (9), 4.629 (9), 3.156 (10), 3.090 (6), 2.925 (5), 2.768 (5), 2.320 (4) and 2.235 (4).
This mineral is named in honour of the French chemist L. C. H. Macquart. The species and name have been approved by the Commission on New Minerals and Mineral Names, IMA.
The structure of ferrarisite, Ca5(HAsO4)2(AsO4)2 . 9 H2O, disorder, hydrogen bonding and polymorphism with guerinite
Authors: Catti Michele , Chiari Giacomo , Ferraris Giovanni 
Published: November 2019

By an automatic diffractometer (MoKα radiation) 2 810 observed reflections were measured on a single crystal of ferrarisite from Sainte-Marie-aux-Mines (Alsace), with the following unit-cell parameters : a = 8.294(4), b = 6.722(3), c = 11.198(5) Å, α = 106.16(4), β = 92.94(4), γ = 99.20(4)° ; Z = 1, space group P[-1]. The structure was solved by direct methods and refined by least-squares to R = 0.033. One water molecule is disordered over two centrosymmetric positions, and presumably that also implies disorder of hydrogen atoms of other water molecules. Two out of the three independent Ca atoms coordinate, in a very irregular way, seven oxygen atoms. These polyhedra, together with the As tetrahedra, build up (001) layers by sharing edges and vertices. The third Ca atom, which is in special position, has nearly regular octahedral coordination and is sandwiched between the layers, with the formation of very large [010] (and smaller [100]) channels at the border of which the water molecules lie. Possible further occupation of sites in the channels is pointed out. Polymorphism with guerinite, relationships with picropharmacolite and dehydration are discussed.

A transmission electron microscope study of naturally deformed orthopyroxene. II : mechanics of kinking
Authors: McLaren Alexandre C. , Etheridge M. A. 
Published: November 2019

Kink bands (KBs) and kink band boundaries (KBBs) in naturally deformed orthopyroxene have been studied by optical and transmission electron microscopy. The KBs are in general not simple and symmetrical and have features characteristic of both ideal kink bands (as defined by Orowan, 1942) and deformation bands (as defined by Mott, 1952). Two closely-related mechanisms (which involve the pile-up of dislocations belonging to a single slip system) are proposed for the development of the observed KBs. The KBBs are also complex structures up to 4 µm wide consisting of a very fine-grained (essentially amorphous) alteration product and discrete grains of orthopyroxene. However, there is evidence that originally the KBBs consisted of a high local density (of the order of 10¹¹ cm⁻²) of piled-up dislocations. The KBBs are, therefore, likely sites for alteration and recrystallization.

Published: November 2019

Les études thermiques et thermogravimétriques différentielles indiquent que les minéraux argileux de l'âge Landénien « Esna Shales » exposés au pied de Gebel Gurnah sont essentiellement formés d'un mélange de kaolinite et de montmorillonite. D'autre part, la pierre à chaux, les lits de marne et de « shales » des formations de Thèbes (Yprésien) les recouvrant immédiatement comprennent un assemblage d'argile formée essentiellement de montmorillonite contrairement aux lits mentionnés ci-dessus.
On discute, du point de vue paléoenvironnement, cette différence quant à la minéralogie des argiles dans la séquence continue de l'âge Landénien˗Yprésien. L'existence de formations rocheus est en outre confirmée par des analyses chimiques.
La société et la terre à Koto Gadang (Indonésie). Éléments pour l'étude d'un «nagari» minangkabau
Authors: Cordonnier Jean-Claude 
Published: November 2019

Land and Society at Koto Gadang (Indonesia). Material for the Study of a «Nagari » Minangkabau.
The Minangkabau are unique in Indonesia, not only because of their matrilineal organization but also because of the exceptional fervor with which they practice meranlau (temporary or permanent emigration). Koto Gadang was chosen for this study because, according to Professor P. E. de Josselin de Jong, "it is known as the nagari which shows the traits and problems typical of Minangkabau society in their most characteristic and extreme form. "As a matter of fact, it is here that the dissensions, conflicts and contradictions of Minangkabau life have reached a point of drastic exacerbation. Although the population has remained stable for the last forty-five years (2,500 inhabitants), its composition has radically changed, full-fledged members of the nagari, in overhelming numbers, permanently abandoning their ancestor's land and being replaced by immigrants. Under these conditions, how can it remain a nagari or territorial community, when community and territory have been dissociated, and how can the ruling diaspora maintain its political and economic domination ? Since the beginning of Dutch rule, the "citizens" of Koto Gadang repudiated agricultural labor and, by means of Western education and professional activities, strove for modern economic success. Koto Gadang adat (common law) defines two groups : a vertical, political, land-holding group (pajung) and a true or biological lineage (paruik). Village society, however, is actually organized along horizontal class lines : batali darah who control land and political power, batali bodi (recent immigrants), settlers of Subarang. Two fundamental aspects of nagarian autonomy have disappeared : the batali darah's monopoly on land and village endogamy. Moreover, adat regulations preserving the inalienability of pusako (ancestral lands belonging to pajung /paruik) have been insidiously ignored or violated. Therefore, far from being an integrated community in full control of its territory, the Koto Gadang nagari is strife-ridden, convulsed by deep-rooted dissensions and no longer able to present a facade of unity to the outside world. Village territory is divided into sawah (rice-fields), inhabited areas with gardens, open fields of permanent or semi-permanent horticulture, ladang (outlying, hilly zones with long fallows), small holdings, samak (previously cultivated forest zones with a large number of clearings) and hutan (forest).
Les Pear, cultivateurs-cueilleurs du Massif des Cardamomes (Cambodge)
Authors: Martin Marie Alexandrine

The Pear , Cultivators-Gatherers in the Cardamom Mountains (Cambodia).
The Pear who belong to the Môn-Khmer family were the inhabitants of the western part of the old Khmer country. Nowadays they are scattered in a few places, in Cambodia and Thailand. According to the oral tradition, together with written documents, it is possible to suggest that, formerly, they were wandering tribes hunting and gathering plants in the forest. Under Khmer sovereignty, they were slaves charged with collecting cardamom ; they then began to lead a semi-sedentary life and probably started to grow plants. We do not know at which period they settled in villages. Referring to the etymology of the word sâmré, it may be that, before wandering in the forest, the Pear were sedentary cultivators as well as gatherers, a condition which is theirs today.

Objetivo: Evaluar la ocurrencia de complicaciones del procedimiento y su tratamiento.
Métodos: Este trabajo tuvo un componente descriptivo sobre las complicaciones del uso de prótesis y su tratamiento y un componente de asociación respecto a la administración del tratamiento oncológico con intención paliativa y su resultado respecto a la supervivencia global. Se revisaron 150 pacientes desde enero de 2011 hasta julio de 2017 que requirieron este procedimiento en el Instituto Nacional de Cancerología (INC).
Resultados: La etiología que más frecuentemente causó obstrucción del tracto de salida gástrico fue el cáncer de estómago, seguido del cáncer pancreatoduodenal, tumores malignos de la vía biliar y otros, incluso fuera del sistema digestivo. Se documentó un porcentaje de éxito técnico del 98,6% (148/150) y éxito clínico del 96% (146/150). Se identificó un 64% (N=96) de pacientes con enfermedad maligna en estadio IV y que tuvieron una incidencia de complicaciones tempranas del 11,33% (N=17) y tardías del 29,33% (N=44). La mayor parte de las complicaciones fueron tratadas por vía endoscópica y el 2,66% (N=4) de los pacientes necesitaron tratamiento quirúrgico.
Conclusiones: Las complicaciones de la colocación de prótesis duodenales pueden ser manejadas en forma exitosa por vía endoscópica en la mayoría de los casos. Los pacientes que además de la colocación de prótesis recibieron tratamiento oncológico presentaron una mayor supervivencia estadísticamente significativa.
