EVALUASI HIDROLOGI DAERAH ALIRAN SUNGAI WOSI DALAM MENGHADAPI CURAH HUJAN EKSTRIM
Authors: Pamuji Khristian Enggar , Hardianti Hardianti 
Published: May 2021

Daerah Aliran Sungai Wosi merupakan DAS yang berada di Distrik Manokwari Barat, Kabupaten Manokwari, Papua Barat. Dalam dekade terakhir, DAS Wosi telah menjadi sumber bencana bagi sebagian penduduk yang tinggal di sekitar atau di daerah hilir sungai Wosi. Ketika curah hujan tinggi, Sungai Wosi tidak dapat menampung debit aliran air, sehingga bencana banjir tidak dapat dihindarkan. Penelitian ini bertujuan untuk mengetahui karakteristik DAS Wosi, menentukan kapasitas tampung maksimum sungai dan mengevaluasi peranan atau fungsi hidrologis DAS Wosi dalam mencegah banjir.
Daerah penelitian berada di Daerah Aliran Sungai Wosi Kabupaten Manokwari. Penelitian ini dimulai dengan pengumpulan data serta analisis data primer dan data sekunder. Data yang dikumpulkan berupa data curah hujan Manowkari, dimensi sungai dan data spatial tutupan lahan di DAS Wosi. Data-data tersebut kemudian digunakan untuk mengetahui karakteristik hidrologi sungai, debit puncak aliran dan kapasitas tapung maksimum sungai.
Hasil yang diperoleh menunjukan bahwa pada beberapa titik pengamatan, kapasitas tampung maksimum sungai lebih kecil dari debit puncak aliran permukaan. Debit puncak ini didominasi oleh aliran permukaan yang berasal dari daerah yang tertutup semak belukar/alang-alang. Meskipun tutupannya hanya 41 % dari total luasan DAS, namum semak belukar/alang-alang telah menyumbang 48 % dari total debit air yang masuk kedalam Sungai Wosi. Hasil evaluasi menunjukan bahwa fungsi hidrologis DAS Wosi sebagai penyangga kejadian puncak hujan dan pengendali banjir saat curah hujan lebat atau ekstrim kurang berfungsi dengan baik.

The linear transformation is a function relating the vector ke . If , then the transformation is called a linear operator. Several examples of linear operators have been introduced since SMA such as reflexive, rotation, compression and expansion and shear. Apart from being introduced in SMA, these linear operators were also introduced to the linear algebra course. Linear transformations studied at the university level include linear transformation in finite dimension vector spaces . The discussion includes how to determine the standard matrix for reflexive linear transformations, rotation, compression and expansion and given shear. Through the column vectors of reflexive, rotation, compression and expansion and shear, a standard matrix of 2x2 size is formed for the corresponding linear transformation. however, in this study, the authors studied linear transformations in dimensioned vector spaces . The results of this study are if known is a vector space with finite and the standard matrix for reflexivity, rotation, expansion, compression and shear is obtained. Each of these linear transformations is performed on x-axis, y-axis and z-axis on to get column vectors. The column vectors as a result of the linear transformation at form the standard matrix for the corresponding linear transformation in the vector space. The standard matrix for linear transformations in the vector space is obtained by determining reflexivity, rotation, expansion, compression and shear. The process of obtaining a standard matrix for linear transformation is carried out by rewriting the standard basis, determining the column vectors, and rearranging them as the standard matrix for each linear transformation in the vector space

At present the laundry business is one of the promising businesses with targeted consumers from the upper middle class who do not have much time to wash clothes at home. Like other industries, laundry also produces wastewater that can have a negative impact on the environment if it is not managed properly. This study characterizes laundry wastewater and looks at its effect on the quality to the groundwater/wells close to the laundry business. Water samples include TSS, TDS, Turbidity, pH , COD, BOD, Phosphate, and Detergent parameters analyzed according to SNI and/or the HACH method (DR3900). Characterization of the laundry wastewater samples show a high level of detergent and phosphate parameters ranging from 27,7-39,4 mg/L and 6,1-27,1 mg/L, respectively with the highest levels corresponds to Laundry wastewater samples at Jalan Baru. The detergent and phosphate contents in all well water samples are still below the required quality standard. Although the concentrations of parameters analysed in the laundry wastewater are very high and above the guidance, it is obvious from the well water samples results that there is no effect of laundry waste waters to the quality of ground waters.

Manokwari Regrency has a tropical climate. This results in significant rainfall. One factor that stimulates rain is humidity. By using binary logistic regression, the model an chance of rainfall based on humidity can be determined. Logistic regression analysis is used to determine the relationship between categorical scale response variables and numeric or categoric scale explanatory variables. If response variable used is nominal scale with two possoble value (0 and 1), then it is called binary logistic regression. Estimation of the model is done by logit transformation. The model produce in this study is g(x) = -23.443 + 0.289 humidity. The accuracy of the model is 70.4 percent and the probability of rain for humidity lowering one unit will be reduced to 0.74.

Published: May 2021

According to the demographic forecast of the development of Russia until 2035, the population of Russia will continue to decline, the trend of low fertility and high mortality will continue, the rate of the Russian leadership on attracting migrants, which will not only save, but also increase the population of Russia [1].
But with an increase in the flow of migrants from the CIS, interethnic and interfaith conflicts are aggravated, growing into serious conflicts like France, Germany, and the United States. In order to reduce tensions and prevent acute conflicts between the host population and migrants, it is necessary to build two-way work to reduce tensions. One of the forms of identifying tensions is to interview the host population.
The purpose of this survey is to identify the characteristics of the attitude of the host population towards migrants from the CIS countries in dynamics, using the example of the city of Chelyabinsk.

OBJECTIVE
Due to the proximity of craniopharyngioma to the optic apparatus, one of the most common complications after surgery is visual deterioration. Intraoperative visual evoked potential (VEP), as a means of real-time visual function monitoring, has been integrated into transsphenoidal surgery for pituitary adenoma to predict postoperative visual outcome. Compared with pituitary tumor, craniopharyngioma often adheres to optic nerves, with increased risk of postoperative visual impairment. Furthermore, extended endoscopic endonasal surgery (EEES) can provide direct visualization of the surgical plane between the craniopharyngioma and the optic nerves, which contributes to analysis of the mechanism of real-time VEP changes during surgery. Therefore, VEP monitoring applied during EEES for craniopharyngioma may have more clinical value. However, only 9 patients who underwent EEES with VEP monitoring for craniopharyngioma have been sporadically reported to date. In this paper, the authors present the largest series to date analyzing the clinical value of VEP to predict postoperative visual outcome in adult patients with craniopharyngioma.

METHODS
Sixty-five adult patients who underwent EEES with intraoperative VEP monitoring for primary craniopharyngioma were retrospectively reviewed. The association between changes in VEP amplitude and postoperative visual outcome was determined. In addition, other potential prognostic factors with regard to postoperative visual outcomes were included in the analysis.

RESULTS
Gross-total resection was achieved in 59 patients (90.8%). Reproducible and stable VEP was recorded in 128 of 130 eyes (98.5%). During surgery, VEP remained stable in 108 eyes, 10 (9.3%) of which had new visual acuity (VA) and/or visual field (VF) defects after surgery. Transient VEP decrease was recorded in 15 eyes, 4 (26.7%) of which had visual deterioration. Of the 5 eyes with permanent VEP decrease, 3 (60%) experienced postoperative visual impairment. Permanent VEP decrease (OR 19.868, p = 0.007) and tight adhesion (OR 6.104, p = 0.040) were independent adverse factors for postoperative VA deterioration. Tight adhesion (OR 7.150, p = 0.002) and larger tumor volume (OR 1.066, p = 0.001) were significant risk factors for postoperative VF defects.

CONCLUSIONS
Intraoperative VEP monitoring can serve as a real-time warning to guide surgeons to avoid postoperative visual impairment. It effectively predicted VA changes in adult patients with craniopharyngioma after EEES. Tight adhesion and larger tumor volume were also strong predictors of postoperative visual impairment.

OBJECTIVE
Craniocervical junction (CCJ) chordomas are a neurosurgical challenge because of their deep localization, lateral extension, bone destruction, and tight relationship with the vertebral artery and lower cranial nerves. In this study, the authors present their surgical experience with the endoscope-assisted far-lateral transcondylar approach (EA-FLTA) for the treatment of CCJ chordomas, highlighting the advantages of this corridor and the integration of the endoscope to reach the anterior aspect and contralateral side of the CCJ and the possibility of performing occipitocervical fusion (OCF) during the same stage of surgery.

METHODS
Nine consecutive cases of CCJ chordomas treated with the EA-FLTA between 2013 and 2020 were retrospectively reviewed. Preoperative characteristics, surgical technique, postoperative results, and clinical outcome were analyzed. A cadaveric dissection was also performed to clarify the anatomical landmarks.

RESULTS
The male/female ratio was 1.25, and the median age was 36 years (range 14–53 years). In 6 patients (66.7%), the lesion showed a bilateral extension, and 7 patients (77.8%) had an intradural extension. The vertebral artery was encased in 5 patients. Gross-total resection was achieved in 5 patients (55.6%), near-total resection in 3 (33.3%), and subtotal resection 1 (11.1%). In 5 cases, the OCF was performed in the same stage after tumor removal. Neither approach-related complications nor complications related to tumor resection occurred. During follow-up (median 18 months, range 5–48 months), 1 patient, who had already undergone treatment and radiotherapy at another institution and had an aggressive tumor (Ki-67 index of 20%), showed tumor recurrence at 12 months.

CONCLUSIONS
The EA-FLTA provides a safe and effective corridor to resect extensive and complex CCJ chordomas, allowing the surgeon to reach the anterior, lateral, and posterior portions of the tumor, and to treat CCJ instability in a single stage.

Experimental researches of a two-level air-jet protection of an open surface of industrial baths of the big sizes
Authors: Korbut V. , Rybachov S.G. 
Published: May 2021

The developed two-level air-jet screen of an industrial bath is experimentally investigated. The principle of its operation is the supply of air by a shielding jet at the upper level and the suction of polluted air at the lower level symmetrically from opposite sides. At this stage of experimental research, the velocity fields and the nature of the interaction of inflow jets and suction flares have been studied. When determining the geometric dimensions of the air-jet screen structure, the location of key components and system elements, it is important to know, ensure and not exceed the allowable values of air flow velocity above the surface of the liquid mirror. During the observations of the aerodynamic properties of two-level air-jet screens, questions arose about the need to use flat rotational flows and control the velocity field in their interaction. Minimization of the interaction of inflow jets and flares of suction is the basis of the concept of designing a sсreen of this type. The shielding conditions have been experimentally confirmed due to the stabilization of the velocity field above the bath surface. The corresponding dependencies of change of formation of the protective air screen from the basic parameters as that a ratio of velocity "inflow-removal" and geometrical characteristics of a design are defined. For the developed air-jet screen of galvanic baths experimentally determined conditions of effective shielding are as follows: the ratio of the width of the slot for ejection of air from the working area to the width of the gas-tight wall is 0.75, and the ratio of screening jet velocity to air removal rate is within 0.3-2.45. This achieves a capture efficiency of up to 90 %. The expediency of arranging an ejection slot under the air supply slot to increase the flow rate and range of the jet has been confirmed.
