Authors: Yusuf Yusnidar , Fitriani Fitriani , Yuniarti Fitri
Published: December 2019

Proses sintesis kimia dari industri farmasi menghasilkan air limbah yang memiliki  karakter bervariasi. Pembuangan bahan limbah seperti obat yang tidak digunakan lagi, fasilitas untuk produksi farmasi, limbah rumah sakit,ini  merupakan sumber polutan. Lakase (EC.1.10.3.2) merupakan enzim oksidoreduktase, termasuk dalam kelompok enzim yang disebut protein tembaga biru (blue copper protein), protein enzim ini mengandung logam tembaga katalitik, yang dapat mengikat oksigen molekuler dan dapat mengoksidasi substrat kaya elektron yang berasal dari fenolik dan non-fenolik dengan air dengan mekanisme reaksi katalis-radikal. Lakase terdapat pada  tanaman tingkat  tinggi yang sudah lapuk, seperti halnya jamur, bakteri dan serangga, dan kelompok yang paling banyak ditemukan dari enzim hingga saat ini berasal dari jamur, memiliki fungsi lakase yang beragam. Model kimia yang dipilih untuk penelitian ini adalah diklofenak dan ibuprofen, karena merupakan obat yang muncul dengan frekuensi terbanyak dalam analisis air limbah akibat konsumsi yang digunakan sebagai anti-inflamasi dan analgesik. Isolasi parsial enzim lakase menggunakan garam amunium sulfat, aktivitas enzim lakase diuji potensinya sebagai katalis  reaksi biodegradasi limbah farmasi. Sampel sebagai bahan aktif secara umum dievaluasi dengan secara eksperimental untuk melihat degradasi biologis  sederhana, yaitu menggunakan lakase mentah dari spesies Trametes. Hasil optimal dicapai sebagai enzim mentah dengan cara diendapkan menggunakan aseton dengan kadar 60%; aktivitas spesifik ditemukan menjadi 0,67 (unit / mg), dan menunjukkan dapat dimanfaatkan untuk menangani pengurangan bahan limbah farmasi berbahaya. Biomodifikasi sangat diharapkan untuk dilakukan pada penelitian selanjutnya  karena memiliki efek positif yang dapat menurunkan tingkat toksisitas dari obat-obatan yang terdapat sebagai limbah.

Authors: Abramovic Biljana , Uzelac Maria , Fincur Nina
Published: December 2019

In this work, the efficiency of direct photolytic and photocatalytic
degradation of thiotriazinone, stable hydrolysis product of antibiotic
ceftriaxone, was examined. The efficiency of photocatalytic degradation of
0.05 mmol/dm3 thiotriazinone solution was investigated using commercially
available TiO2 Hombikat catalyst under simulated solar irradiation, as well
as in the absence/presence of ammonium persulfate ((NH4)2S2O8) as electron
acceptor. It was found that the optimal conditions for photocatalytic
degradation of thiotriazinone were: catalyst loading 1.0 mg/cm3 of TiO2
Hombikat, electron acceptor 3 mmol/dm3 of (NH4)2S2O8 solution, and pH 7.6.
Under the stated conditions 76.0% of thiotriazinone was degradated after 60
min of irradiation. The kinetics of degradation was followed by UFLC-DAD
technique.

Authors: Milinkovic-Budincic Jelena , Petrovic Lidija , Fraj Jadranka , Bucko Sandra , Katona Jaroslav , Spasojevic Ljiljana
Published: December 2019

Chitosan is a cationic biopolymer, which attracts more and more attention in
recent years, due to its exceptional physical and chemical properties,
expressive biocompatibility and possibilities of obtaining from renewable
sources. Formed polymer/surfactant complexes affect changes in the
rheological properties and the final result is the formation of coacervates.
The purpose of this study was to investigate the rheological properties of
aqueous solutions of cationic polyelectrolyte, chitosan and sodium lauryl
ether sulfate (SLES), an anionic surfactant, widely used in the cosmetics
industry. Using the Thermo Haake RS600 rheometer, changes in the rheological
and elastic properties of chitosan and SLES mixtures have been identified,
gained as a result of the interaction of the components. In all examined
samples coefficient of thixotropy was increasing with increase SLES
concentration and achieves a maximum value at the mass ratio chitosan:SLES
1:2, after which it reduces. The oscillatory measurements in mixtures,
performed by amplitude sweep method at low oscillating frequency 1 Hz, show
that the linear viscoelastic region increases with increasing SLES
concentration up to the same chitosan:SLES mass ratio. By monitoring the
changes in the rheological parameters of the mixtures over five days, it was
observed that the viscosity, the coefficient of thixotropy and elasticity
were increasing, indicating that changes in the system occur over a longer
period of time. In that manner, obtained results indicate the possibility of
using rheological methods for a more detailed description of the interaction
in the chitosan/SLES mixtures, important for their application in cosmetics
and pharmaceutical industries.

Published: December 2019

This study was conducted to investigate the effect of the addition of
buckwheat flour, as well as the influence of buckwheat grain pretreatment,
on betaine content in wholegrain wheat pasta. The buckwheat is traditionally
used in the human diet for centuries due to its nutritional benefits and
positive effect on health such as plasma cholesterol level reduction,
anticancer and anti-inflammatory activity. On the other side, betaine is a
bioactive compound naturally present in cereals and pseudocereals, important
for demethylation of homocysteine to methionine which mainly occurs in the
liver. The single screw extruder was used for the production of wholegrain
wheat pasta as a control sample and pasta in which wholegrain wheat flour
was substituted with one of two types of wholegrain buckwheat flour
(autoclaved wholegrain buckwheat flour and flour without treatment), with a
level of substitution from 10 to 30%. High-performance liquid chromatography
with evaporative light scattering detector (ELSD) was used to analyze
betaine content in different pasta samples. Betaine content in wholegrain
wheat pasta was 30.07 mg/100 g f.w. (i.e. 34.92 mg/100 g d.w.) and the
highest content of betaine in pasta enriched with wholegrain buckwheat flour
was detected in a sample with 10% flour substitution (21.63 mg/100 g,
apropos 24.22 mg/100 g d.w.) compared to other levels of substitution.
Following the presented results, autoclaving pretreatment of buckwheat grain
prior to buckwheat flour production did not show important differences in
betaine content when pasta made with this type of flour was compared with
pasta made with untreated buckwheat flour.
Electrobaromembrane apparatuses: Classification and particular application for wastewater treatment
Authors: Lazarev Sergey , Kovalev Sergey , Shestakov Konstantin
Published: December 2019

The aims of this work are developing the electrobaromembrane apparatus
classification and study of the particular case of electrobaromembrane
process application for wastewater treatment in engineering industries. The
multilevel classification of electrobaromembrane processes, which takes into
account several factors at once, is proposed. A particular case of
electrobaromembrane process application for treatment of the galvanic
solution produced by JSC "Zavod Tambovpolimermash" is studied in this work.
The research was carried out on the experimental electrobaromembrane plant
with flat chambers. In addition, some approximation functions and their
numerical values of empirical coefficients were obtained for experimental
data of the specific flow and the retention factor of membranes OPMN-P and
AMN-P. The result comparison of nanofiltration and electronanofiltration
processes shows that the permeability of the solution through the membrane
pores increases when a constant electric current density is applied to the
test system. During nanofiltration, process membranes are compacted due to
the overpressure increase. This directly affects the driving force of the
membrane separation process for a particular type of solution, thereby the
retention factor of porous membranes increases. Retention factor values do
not differ a lot for certain types of ions. In contrast,
electronanofiltration process is characterized by the selectivity of
membranes with respect to a certain type of ions. The near-cathode OPMN-P
membrane mainly passes thought itself the Zn2+ cations and holds the Cl- and
SO4 2- anions, while the near-anode AMN-P membrane mainly passes thought
itself the Cl- and SO4 2- anions and holds the Zn2+ cations.
Packed bed absorption column: Hydrodynamics and mass transfer
Authors: Sovilj Milan , Nikolovski Branislava , Spasojevic Momcilo , Mauhar Sinisa
Published: December 2019

This paper presents the results of the determination of the hydrodynamic
characteristics and mass transfer in the pilot plate absorption column. The
experimental values of the pressure drop in the countercurrent flow of air
and water through the column were obtained. The graphic dependence of the
pressure drop of air per unit height of the layer of packing (?P/h) on the
apparent air velocity (Ug) through the dry charge was shown to be in the
form of a quadratic function. From the graphical function which shows the
dependence of the pressure drop per unit height of the layer of filling
(?P/m) on the apparent air velocity during the countercurrent flow of the
phases (water and air), three fields of the interaction of the phases were
observed: a) the area of low load, at low apparent air velocities, b) the
area of high load, at higher air velocities, and c) the flooding area, when
the liquid completely fills the cavities and the working gas in them starts
bubbling. The overall mass transfer coefficient (Kg) of the air-CO2-water
system depends on the flow rate of the gaseous phase and the composition of
the starting gas mixture (air-CO2). With the increase in the total gas flow
rate, with a constant composition of the starting gas mixture and constant
fluid flow, the overall mass transfer coefficient increases. Increasing the
amount of CO2 in the starting gas mixture at a constant flow rate of fluid
and a constant ratio of the molar flow of the inert in the liquid and the
gas-phase (L'/G') decreases the overall mass transfer coefficient.
Cloud point extraction procedure for preconcentration and determination of lead(II) ions using triton X-100 at room temperature
Authors: Suljkanovic Mersiha , Suljagic Jasmin , Hasic Nusreta , Hodzic Selmina
Published: December 2019

A Cloud point extraction (CPE) procedure was presented for preconcentration
of lead(II) ions, after complexation by 18-crown-6 (18C6) and extraction
with Triton X-100 at proposed experimental conditions. After separation of
surfactant - rich phase, content of Pb(II) ions in remaining solution was
measured by Flame Atomic Absorption Spectrometry (FAAS). The experimental
conditions such as pH, temperature, concentration of Triton X-100,
concentration of 18C6, incubation time, type and concentration of added
electrolyte, were evaluated. Results showed that among investigated
electrolytes (NaCl, Na2SO4 and Na2CO3) the amount of 0.9 mol/L Na2CO3 lowers
cloud point temperature of Triton X-100 to 22?C (room temperature during the
experiment), thus simplifying the extraction procedure. After an incubation
time of 5 minutes and using the concentration of 1.2?10-3 mol/L Triton X-100
and 1.5?10-4 mol/L 18C6 (1:1 stoichiometric ratio for 18C6:Pb), 60% of lead
(II) ions were efficiently removed from investigated solution.

Published: December 2019

In this study, the effects of kombucha inoculum as non-conventional starter
culture on fatty acids composition of fermented milk, compared to a
commercial probiotic (ABT-7) and yoghurt (YF-L812) starter cultures, during
21 days of storage was investigated. Fatty acids composition was determined
by gas chromatography-mass spectrometry after the previous extraction of
lipids and derivatization. The atherogenic (AI) and thrombogenic (TI)
indices determined on the basis of fatty acids composition have been used
for evaluation of the nutritive lipid quality of the fermented dairy
products. The most significant levels of fatty acids in fermented milk
products were palmitic, followed by oleic, stearic and myristic fatty acids.
Fermented milk products were characterized by low atherogenic (2.14-2.39)
and thrombogenic (2.91-3.18) indices, suggesting their consumption could
have a favorable effect on human health. The AI and TI were comparable
during the storage of fermented milk samples. Starter culture did not affect
the health-related fatty acid composition of fermented milk products during
storage.

The paper is devoted to further study of a certain type of infinitesimal
transformations of twodimensional (pseudo-) Riemannian spaces, which are
called rotary. Aninfinitesimal transformation is called rotary if it maps
any geodesic on (pseudo-) Riemannian space onto an isoperimetric extremal of
rotation in their principal parts on (pseudo-) Riemannian space. We study
basic equations of the infinitesimal rotary transformations in detail and
obtain the simpler fundamental equations of these transformations.

Large choledochal cyst initially interpreted as Mirizzi syndrome - case report and literature review
Authors: Milosavljevic Vladimir , Tadic Boris , Grubor Nikola , Knezevic Djordje , Matic Slavko
Published: December 2019

Introduction. Choledochal cysts are congenital anomalies manifested as focal or diffuse cystic dilatation of the bile ducts. They are mostly diagnosed in childhood. The magnetic resonance and surgical management are the gold standard diagnostic and treatment modality. Case outline. We present a male patient who was presumed to have Mirizzi syndrome. This presumption was discarded by additional imaging procedures and by later surgical treatment. It was confirmed that it was a large choledochal cyst filled with stones. Considering the diagnosis and good patient?s general condition, we opted for surgical treatment. Conclusion. There are several surgical techniques that can be used in the treatment of choledochal cysts, wherein each is intended as a complete resection of the cyst with histological confirmation. Operative techniques do not affect the outcome of the treatment, but the time and extent of surgical resection, as well as any metaplasia of the epithelium, do.

Published: December 2019

This study aims to investigate the improvement of students' mathematical concepts understanding through the application of Guided, Explained, Collaborated & Evoked (GECE) Learning Strategy. The GECE Learning Strategy originates from the integration of the Auditory Intellectually Repetition (AIR) learning model and Guided Discovery learning model. The quasi-experimental with nonequivalent control group design was employed in this study. The instruments used were a test in the form of a description based on real-world concepts and a questionnaire to determine students' responses in the process of learning mathematics. Based on the results of hypothesis testing using the Mann-Whitney test, it was obtained that p <α (0.001 <0.005) which shows that the application of the GECE learning model affects students' mathematical concept understanding with n-gain of 0.62 (medium category). The effectiveness of the learning model applied was measured using Cohen's formula and a value of 1.88 (high category) was obtained. The results were also supported by positive students' responses of 3.45 which means that the integration of the Auditory Intellectually Repetition (AIR) learning model and Guided Discovery learning model could effectively improve students' mathematical concepts understanding.

The aim of this research was to describe the representation of mathematics of RME based on student's personality type, the conceptual understanding in RME based on student's personality type. In this research, 8 PGSD students from artisan, idealist, guardian, and rational personality types were selected as subjects. The methods used in this research were tests, interviews, and documentation of personality type questionnaires of the students according to (Keirsey, 1984)). The tests and interviews were analyzed to describe the conceptual understanding and representation abilities of the students. The results of this research were that the students with the rational personality type were very good at identifying and making examples, traits and conditions. Students with the idealist personality type were very good at identifying verbally and in written form. All four personality types’ conceptual understanding when identifying and distinguishing concepts was still poor. Meanwhile, for the mathematical representation aspect, all four personality types were very good at visual mathematical representation in the form of figures and tables.
Importance of Modern Communication Technologies in Monitoring Compliance of Patients with Chronic Myeloid Leukemia
Authors: Matić Nikolina , Matić Ivica
Published: December 2019

Compliance
is a term that applies to the patient’s ability to correctly follow
advice and instructions regarding medications, diet, and activity. The
nurse, as an important factor in the multidisciplinary team, has a
special responsibility in monitoring the patient’s compliance. It is
essential for patients with chronic malignancies, such as chronic
myeloid leukemia, which is nowadays mostly treated successfully by
continuous and regular monitoring and application of therapy. The aim
of the present study was to determine whether the nurse’s communication
with patients, which implies the use of information and communications
technology, affects compliance. The study was conducted on a sample of
50 outpatients at the Department of Haematology of the University
Hospital Centre Zagreb. The respondents used some form of modern
communication for three weeks and were re-interviewed for compliance.
The use of modern information technology enhances patient compliance.
Those who were reminded significantly improved the regularity of their
check-ups. After the intervention, the respondents considered reminders
useful in encouraging them to take medicines more regularly and to
attend check-ups.

Introduction. Palliative care has evolved to identify the specific needs of
patients with severe and incurable diseases. An estimated 46,000 patients in the
Republic of Croatia require some form of palliative care. The aim of this study
is to examine nurses’ knowledge of palliative care.

Methods. A cross-sectional study included 198 nurses. The survey was
conducted during March and April of 2017. As a survey instrument, a 2-part
questionnaire was used. The first part dealt with sociodemographic data and the
second part consisted of a standardized palliative care quiz for nursing (PCQN)
questionnaire.

Results. Respondents gave the most correct answers in the area of pain
and other symptoms control. It was found that there was no significant
difference in gender, age, or seniority in knowledge of palliative care.
Respondents who received informal education showed better knowledge.

Conclusion. From the study conducted, we can conclude that nurses have
insufficient knowledge of palliative care.

Published: December 2019

For most foreign language learners, understanding texts written in a foreign language is not an easy thing to do. To help learners in coping with this problem, when teaching reading teachers should provide them with a number of structured tasks that not only focus on students’ reading purpose, but also allow them to confront and reflect upon reading difficulties in socially interactive ways and one of the activities which is appropriate with these tasks is Directed Reading Activity (DRTA). The objective of the research is to compare the behavior of the English reading class students before and after the implementation of DRTA. The subjects of this research were 3 students of LBB Teladan Kudus. The conclusion is that the behavior of the students is better than that before the implementation of DRTA. The students become motivated, active, enthusiastic, paid attention to the teaching learning process, and got involved in the teaching learning process. Considering that DRTA has many benefits for learners especially dealing with learners’ behaviors, it is suggested that this activity should be used by the teacher when teaching reading.

Sukabumi merupakan salah satu kota rawan bencana. Masyarakat yang tinggal di sekitar kota Sukabumi memerlukan informasi kebencanaan untuk membantu masyarakat menghadapi bencana. Salah satunya ialah lingkungan masyarakat di Rumah Sakit Umum Daerah (RSUD) R. Syamsudin yang menggunakan informasi seputar bencana dari siaran program Radio Bunut. Radio ini memiliki program kebencanaan bagi pasien dan staf rumah sakit. Artikel ini bertujuan untuk menyajikan hasil analisis terhadap program kebencanaan bagi pasien dan staf RSUD R. Syamsudin di Radio Bunut yang terbagi menjadi tiga tahap; tahap pra bencana, saat bencana dan tahap pasca bencana. Penelitian ini dilakukan menggunakan metode studi kasus. Adapun teknik pengumpulan data melalui wawancara mendalam, observasi dan tinjauan literatur. Berdasarkan hasil penelitian, Radio Bunut melakukan tiga tahap kegiatan kebencanaan yaitu, pra bencana (pre-event), saat bencana (event), dan tahap pasca bencana (post-event). Pada tahap pra bencana, radio melakukan edukasi, sosialisasi dan simulasi bencana. Kegiatan edukasi berupa pengenalan potensi bencana, sedangkan sosialisasi yaitu informasi pra bencana, dan simulasi bencana berupa pelatihan langsung menghadapi bencana. Dalam kegiatan saat bencana, Radio Bunut melakukan tanggap darurat berupa pengarahan dan praktik Standar Operasional Prosedur (SOP) siaga bencana, dan pengenalan informasi jalur evakuasi. Kegiatan pasca bencana, radio melakukan pemulihan kembali (recovery) dan evaluasi. Program pemulihan kembali dalam bentuk kegiatan siaran on air dan off air untuk menghibur korban bencana. Pada kegiatan evaluasi, radio menganalisis tujuan, target, dan keberhasilan program pasca bencana dan saat bencana yang dilakukan. Radio Bunut sebagai media komunikasi kebencanaan telah konsisten menyiarkan informasi bencana pada pasien dan staf rumah sakit.
Komunikasi sosial pemerintah dalam penyebaran informasi perbatasan Negara Indonesia dan Timor Leste

Published: December 2019

Tindakan pelanggaran perjanjian bilateral tahun 2005 oleh masyarakat Timor Leste memasuki lahan Naktuka sebagai area netral di antara perbatasan kedua negara, menimbulkan kecemasan dan mendorong masyarakat Netemnanu Utara (Indonesia) untuk mengambil tindakan anarkis. Sebagai antisipasi, diperlukan peran pemerintah Indonesia untuk menjalin komunikasi dengan masyarakat perbatasan melalui lembaga terkait, khususnya Badan Pengelola Perbatasan (BPP) Kabupaten Kupang yang bertanggung jawab mengurus wilayah perbatasan negara di wilayah Kabupaten Kupang. Penelitian ini bertujuan untuk mengetahui komunikasi sosial antara pihak BPP Kabupaten Kupang dengan masyarakat Netemnanu Utara berdasarkan jenis, proses, tahapan penerimaan informasi oleh masyarakat, dan karakteristik masyarakat Netemnanu Utara dalam mengadopsi informasi mengenai persoalan tersebut. Metode penelitian menggunakan kualitatif dengan pendekatan studi kasus. Hasil penelitian menunjukkan bahwa komunikasi sosial antara masyarakat dan pihak pemerintah daerah dengan pendekatan sosial budaya, selain itu adanya keputusan pemerintah pusat sebelumnya yang menyetujui penerapan perjanjian traktat 1904 bersama pihak Timor Leste menjadikan komunikasi sosial pemerintah gagal dan menimbulkan penolakan masyarakat karena dianggap tidak sesuai dengan sejarah hidup masyarakat Netemnanu Utara. Penelitian ini menyimpulkan, pemerintah menggunakan beragam jenis dan proses komunikasi sesuai situasi dan karakter masyarakat Netemnanu Utara. Penerimaan masyarakat atas inovasi atau kebaruan informasi terjadi dalam 3 tahap yaitu pengetahuan, persuasi dan tahap pengambilan keputusan. Tahap implementasi dan konfirmasi tidak berlanjut, karena masyarakat menilai minimnya pengetahuan pemerintah, tidak pernah dilibatkan, dan kesepakatan tersebut bertentangan dengan unsur budaya masyarakat perbatasan. Saran, pemerintah pusat maupun daerah sebaiknya selalu melibatkan masyarakat dalam setiap pengambilan keputusan berkaitan dengan batas wilayah antara kedua negara, sebelum melakukan kesepakatan untuk menghindari kegagalan komunikasi dan meminimalisir konflik.

Proper classes generated by τ- closed submodules
Authors: Durğun Yılmaz , Çobankaya Ayşe
Published: December 2019

The main object of this paper is to study relative homological aspects as well as further properties of τ -closed submodules. A submodule N of a module M is said to be τ -closed (or τ -pure) provided that M/N is τ -torsion-free, where τ stands for an idempotent radical. Whereas the well-known proper class 𝒞losed (𝒫ure) of closed (pure) short exact sequences, the class τ −𝒞losed of τ -closed short exact sequences need not be a proper class. We describe the smallest proper class 〈τ − 𝒞losed〉 containing τ − 𝒞losed, through τ -closed submodules. We show that the smallest proper class 〈τ − 𝒞losed〉 is the proper classes projectively generated by the class of τ -torsion modules and coprojectively generated by the class of τ -torsion-free modules. Also, we consider the relations between the proper class 〈τ − 𝒞losed〉 and some of well-known proper classes, such as 𝒞losed, 𝒫ure.

Published: December 2019

In this paper, we study the split common fixed point problem in Hilbert spaces. We find a common solution of the split common fixed point problem for two demicontractive operators without a priori knowledge of operator norms. A strong convergence theorem is obtained under some additional conditions and numerical examples are included to illustrate the applications in signal compressed sensing and image restoration.
Irrigation with treated wastewaters and the protection of Hennaya groundwater – Tlemcen, Algeria
Authors: Bemmoussat Abdelkader , Adjim Mohammed , Bensaoula Fouzia
Published: December 2019

The Henaya Irrigated Perimeter (HIP) is an agricultural area irrigated by treated wastewater (TWW) of Ain El Hout treatment plant. Various analyses have shown that i) this water has low concentration of heavy metals and toxic elements, ii) the average values of the physicochemical parameters for 136 samples are satisfactory (29.2 mg O2∙dm−3 for chemical oxygen demands – COD, 13.14 mg O2∙dm−3 for biological oxygen demands – BOD, 14.2 mg∙dm−3 of suspended matter – SM, 1.82 mg∙dm−3 of N-NO3, 7.7 for pH and 927.74 μS∙cm−1 for electric conductivity – EC). Thirdly, it contains a high number of bacteria and nematodes (7200 CFU∙(100 dm3)−1 for faecal coliforms and 30 eggs∙dm−3 for intestinal Nematodes) which makes it dangerous for groundwater contamination.

The objective in this work is to characterize the TWW and evaluate the impact of it use for irrigation on the quality of Hennaya groundwater. Before this, one has to prove that there is an amount of TWW that feeds the water table to show that there is a risk of pollution. We then estimated the aquifer minimum recharge value by TWW using the Thormthwaite method. The estimation has given 92 mm which is an important quantity. The results of the groundwater microbiological analyses reveal no sign of contamination. The cause is the efficiency of the degradation of pollutants of the Vadose zone. The soil purifying power Md of the HIP was evaluated by the Rehse method and gave values ranging from 2.1 to 12.7 which indicated a complete purification.
