As a tropical country, Indonesia has riches of biomass. Cassava is one of biomass which contains plenty of carbohydrate. Carbohydrate then is utilized as a source for producing bioethanol. In producing of bioethanol, the process also yield side product named vinasse.Â Vinasse is produced from distillation process of solution containing ethanol which has concentration between 7 and 10%. Vinasse contents very high organic substances with COD and BOD concentration amounting of 30,000 mg/L and 27,000 mg/L respectively. Vinasse was then treated in an anaerobic process by using fixed bed digester. Anaerobic fixed bed digester volume was 225 L. The digester was provided with support materialsmade from cutted PVC pipe. The support materials has void volume of 93%. Therefore, the effective volume of the digester was 209 liters. The digester was operated by upflow mode. Research result from this experiment will be utilized as basic design for producing biogas at a bioethanol plant located in Lampung Tengah. Capacity of the plant is 8,000 litres of bioethanol per day. Whereas the vinasse produced is 100,000 litres per day.Keywords: bioethanol, vinasse,fixed bed digester, biogas, casava waste water

Isolate I-5 was isolated from Ciseeng hot spring, West Java and was identified as Bacillus licheniformis I-5. The isolate produces extracellular xylanolytic enzymes on Oatspelt containing Luria broth agar medium. Optimal activity of the crude enzyme was Â observed at 50ÂºC and pH 7. The effect of sodium dodecyl sulphate, b-mercaptoethanol and Triton-X100 were observed. Incubating the crude enzyme in 1.5% SDS and 1.5% b-mercaptoethanol at 50oC for 90 minutes then adding Triton-X100 at final concentration of 3.5% for 45 minutes only reduced 5.75% of the initial enzyme activity. SDS/PAGE and zymogram analysis showed that at least two xylanolytic enzymes presence in the crude enzyme. The molecular weight of the enzyme was estimated about 127 and 20kD. The enzyme hydrolysed xylan into xylobiose, xylotriose and other longer xylooligosaccharides. Thermal stability of the crude enzyme was observed at 50, 60, and 70oC and pH 7 and 8. The results showed that the half time of the crude enzyme incubated at 50, 60, and 70oC pH 7 was 2 hours 55 minutes; 2 hours 33 minutes and 1 hour 15 minutes respectively. The half time at 50, 60 and 70oC, pH 8 was 2 hours 48 minutes; 1 hour 22 minutes and 1 hour 9 minutes respectively.keywords: Xilanase, Bacillus licheniformis I-5, thermal stability

Published: August 2020

Thin films whose compositions can be expressed by (GeS2)100-xGax (x=0, 6,12,18) formula were obtained by thermal evaporation technique of bulk material at a base pressure of ~10-5 torr. Optical transmission spectra of the films were taken in the range of 300-1100 nm then the optical band gap, tail width of localized states, refractive index, extinction coefficient were calculated. The optical constants were found to increase at low concentration of Ga (0 to12%) while they decreases with further addition of Ga. The optical band gap was found to change in opposite manner to that of optical constants. The variation in the optical parameters are explained in terms of average bond energy of the system.

Different methods for characterizing surface roughness using laser speckle technique
Authors: Al-Quzweny Mayada B. 
Published: August 2020

In this work, results from an optical technique (laser speckle technique) for measuring surface roughness was done by using statistical properties of speckle pattern from the point of view of computer image texture analysis. Four calibration relationships were used to cover wide range of measurement with the same laser speckle technique. The first one is based on intensity contrast of the speckle, the second is based on analysis of speckle binary image, the third is on size of speckle pattern spot, and the latest one is based on characterization of the energy feature of the gray level co-occurrence matrices for the speckle pattern. By these calibration relationships surface roughness of an object surface can be evaluated within these relations ranges from single speckle pattern image which was taken from the surface.

Authors: Hameed B. S. 
Published: August 2020

The elastic transverse electron scattering form factors have been studied for the 11Li nucleus using the Two- Frequency Shell Model (TFSM) approach. The single-particle wave functions of harmonic-oscillator (HO) potential are used with two different oscillator parameters bcore and bhalo. According to this model, the core nucleons of 9Li nucleus are assumed to move in the model space of spsdpf. The outer halo (2-neutron) in 11Li is assumed to move in the pure 1p1/2, 1d5/2, 2s1/2 orbit. The shell model calculations are carried out for core nucleons using the spsdpf-interaction. The elastic magnetic electron scattering of the stable 7Li and exotic 11Li nuclei are also investigated through Plane Wave Born Approximation (PWBA). It is found that the difference between the total form factors of unstable isotope (11Li halo) and stable isotope 7Li is in magnitude. The measured value of the magnetic moment is also reproduced.
Nucleon momentum distributions and elastic electron scattering form factors for 58Ni, 60Ni, 62Ni, and 64Ni isotopes using the framework of coherent fluctuation model
Authors: Ojaimi Hasan F. 
Published: August 2020

The nucleon momentum distributions (NMD) and elastic electron scattering form factors of the ground state for some 1f-2p-shell nuclei, such as 58Ni, 60Ni, 62Ni, and 64Niisotopes have been calculated in the framework of the coherent fluctuation model (CFM) and expressed in terms of the weight function lf(x)l2 . The weight function (fluctuation function) has been related to the nucleon density distribution (NDD) of the nuclei and determined from the theory and experiment. The NDD is derived from a simple method based on the use of the single particle wave functions of the harmonic oscillator potential and the occupation numbers of the states. The feature of the long-tail behavior at high momentum region of the NMD’s has been obtained by both the theoretical and experimental weight functions. The calculated elastic electron scattering form factors for considered isotopes are in reasonable agreement with those of experimental data throughout all values of momentum transfer q.

Published: August 2020

This paper displays the effect of uncoated and coated chopped carbon fibers with alumina Al2O3 or Tri calcium phosphate (TCP) on the impact strength of acrylic poly methyl methacrylate (PMMA) denture base resin. To improve bonding between carbon fibers and coating materials powders, the surface of carbon fibers has been treated with Para amino benzoic acid (C9H10N2O3) and poly vinyl alcohol (PVA) was also used. The morphology of the coating layers has been examined by field emission scanning electron microscope (FE-SEM). From the results, PMMA reinforced with uncoated chopped carbon fiber has high impact strength value but still have bad aesthetic. Samples prepared by coated carbon fiber with Al2O3 or TCP have high impact strength values when compared to control group with good aesthetic. Impact strength was increased in samples when PVA increased and fibers amount decreased.

Sistem Perendaman Sesaat (SPS) merupakan salah satu teknologi pada kultur jaringan tumbuhan dimana jaringan tumbuhan direndam secara berkala. Pada saat perendaman, media cair dialirkan dari wadah media cair ke wadah jaringan. Setelah proses perendaman selesai, media cair akan mengalir dengan sendirinya dari wadah jaringan ke wadahnya karena wadah media cair ditempatkan lebih rendah dibandingkan wadah jaringan. Sistem perendaman ini terdiri dari lima wadah media cair dan lima wadah jaringan yang dilengkapi dengan sensor level. Data waktu dan lama perendaman disimpan pada micro SD untuk melihat apakah SPS ini berjalan sesuai dengan waktu yang telah ditentukan. Pada saat proses perendaman, udara yang dialirkan menuju wadah media cair divariasikan 1 bar dan 1,5 bar untuk memindahkan air 254,5 ml yang ada dalam wadah media cair. Tekanan 1 bar sudah dapat mengalirkan media cair dari wadahnya ke wadah jaringan dan menimbulkan gelembung-gelembung air yang lebih sedikit dibandingkan tekanan 1,5 bar. Dari hasil data rekaman pada micro SD didapatkan bahwa waktu perendaman pada SPS ini sesuai dengan waktu yang telah ditentukan.
