Authors: Oemiati Nurnilam , Revisdah Revisdah , Rahmawati Rahmawati
Published: March 2021

Salah satu kegiatan pertambangan batubara adalah pengupasan lapisan tanah penutup (overburden) yang diawali dengan penggalian dan pengangkutan menuju area penimbunan (disposal). Lapisan tanah penutup dipindahkan dari lokasi penggaliam (front) menuju disposal memerlukan alat mekanis berupa alat muat Excavator dan alat angkut Heavy Duty. PT. Satria Bahana Sarana memiliki target produksi yang diberikan kepada subkontraktor, sehingga perlu dilakukan analisa produktivitas alat muat dan alat angkut pada pengupasan lapisan tanah penutup lokasi PIT I utara Banko Barat.Persentase ketercapaian target produktivitas berdasarkan rencana pengupasan lapisan tanah penutup (Overburden) sebesar 600 Bcm / Jam. Sedangkan berdasarkan hasil perhitungan kombinasi kerja alat muat dan alat angkut didapat, pada alat muat Excavator sebesar 90% (540,205 Bcm / Jam) sedangkan alat angkut HD sebesar 48,95% (293,727 Bcm / Jam) dari target Hasil produksi berdasarkan perhitungan kurang dari target produksi yang direncanakan. Penyebab tidak tercapainya target produksi adalah mekanisme penyiapan lokasi, pengaruh penyiapan lokasi dan pengaruh keserasian jumlah alat.Dari hasil pengamatan di lapangan dan hasil perhitungan faktor keserasian antara excavator dan heavy duty didapat bahwa hasil MF sebesar 0,642 < 1, artinya alat muat excavator bekerja kurang dari 100% sedangkan alat angkut heavy duty bekerja 100%, sehingga terdapat waktu tunggu bagi alat muat. Dengan demikian jika dilakukan optimasi terhadap kerja efektif alat tersebut, evaluasi jam kerja dan penambahan jumlah excavator dan heavy duty dapat meningkatkan hasil produksi sehingga target dapat terpenuhi.

ПЕРЕДУМОВИ ТА ЕВОЛЮЦІЯ ВПРОВАДЖЕННЯ ПОЛІТИКИ РЕВІТАЛІЗАЦІЇ МІСТ У НІМЕЧЧИНІ
Authors: Горблюк Сергій
Published: March 2021

Стаття присвячена встановленню передумов та основних етапів еволюції політики ревіталізації міст у Німеччині. Акцентовано увагу, що в цьому процесі важливе значення відграє належне та стабільне правове регулювання, а також інституційна пам’ять федеральних урядів, які кардинально не змінювали основні засади політики ревіталізації, а їх удосконалювали.

Розглянуто розширення у процесі еволюції німецької політики комплексу інструментів ревіталізації міст від вирішення переважно житлових проблем (знесення, будівництво, модернізація житлового фонду) до забезпечення різноманітної функціональності та максимальної корисності міського простору, проведення “обережної” ревіталізації, зокрема шляхом розвитку унікальної ідентичності здеградованих територій з акцентом на їхній історичній та культурній спадщині.

Визначено, що відповідальними за проведення ревіталізації та її економічні й соціальні наслідки в Німеччині є місцеві органи публічної влади, втім на ефективність розроблених і впроваджених програм вплинуло широке застосування інструментів громадської партисипації (налагодження тісної комунікації, реалізація “м’яких” проєктів тощо).

Виділено новітні тенденції у сфері ревіталізації міст, які стосуються інтегрованих комплексних дій, спрямованих на реструктуризацію здеградованих територій та їх переорієнтацію відповідно до сучасних вимог (програми перебудови міст). При цьому стають все більш важливими питання сталого розвитку, зокрема ресурсоощадність.

Запропоновано при розробленні політики ревіталізації міст в Україні врахувати питання державної підтримки й залучення приватного сектора до відповідних заходів, правового регулювання діяльності (насамперед, закріплення відповідальності органів місцевого самоврядування та інструментів партисипації), впровадження комплексу інтегрованих дій, орієнтованих на сталий розвитку здеградованих міських територій тощо.

Having to stay at home and disconnected from their social world during the Covid-19 lockdown is stressful for many people, including students. The current paper reports the application of a deep breathing relaxation technique among students from the Faculty of Psychology Universitas Sumatera Utara, to regulate their stress levels at home. Twenty-five students participated in this intervention program. We trained them in a deep breathing relaxation technique and asked them to practice the technique twice a day, in the morning and the evening. We followed their progress for five consecutive days, in which participants filled a stress diary twice a day, in the morning and the evening. Based on the diary, a feedback by a psychologist was sent to each individual participant the next day. We assessed the effectiveness of the intervention program by comparing the students' perceived stress at the pre-intervention phase compared to their stress level at the post-intervention phase. The results showed a significant and meaningful impact of the intervention program, in which students reported lower perceived stress at the post-intervention compared to the pre-intervention phase.

The teaching and learning process has turned from face-to-face into an online method. However, there are several obstacles experienced by schools that implement an online learning system, one of them was the ability of teachers who do not understand various learning application platforms. In addition, the material provided by the teacher is not maximally acceptable to students because most teachers provide learning material from the pages of textbooks or teacher writings (scans, photos, or presentation files). For this reason, it is necessary to have variations in the provision of teaching materials to students by making interesting and creative learning videos using the Movavi Education Set. With learning videos, students can do lessons at home, repeat it, and can ask the teacher some points from it if they don't understand. By using Movavi Education Set, teachers are also free to be creative in making learning videos that can be shared through commonly used communication applications such as e-mail, WhatsApp, line, google classroom and other applications.

Published: March 2021

Straw Mushroom (Volvariella volvaceae) as well asmushrooms edible otherhave been developed in Indonesia, including North Sumatra as a substitute for animal protein. Mushrooms or also known as button mushrooms are vegetables that are recognized to have high nutritional value, and are even believed to have medicinal properties for various types of diseases so that they have a fairly high selling value. Some studies report that in 100 grams of mushroom, only 0.17% fat is contained and even better, this fat is not bad fat. Seeing the high demand because of its nutritional value, and its rich content, its taste that is liked by many people, mushroom cultivation has a very promising market value. Basically until now the demand for mushroom continues to increase, but farmers have not been able to meet market needs. good quality start to be limited. Some farmers have started to switch to alternative planting media which is currently mostly practiced, namely oil palm pulp or empty palm oil bunches (TKKS). EFB is a waste that is very easy and is found mostly around palm oil processing factories, whose use has been limited so far as heating materials for boilers and particle wood, many empty bunches have not been utilized. This service aims to provide training in the form of mushroom cultivation using TKKS, as well as provide training in the form of post-harvest handling which is important given the lack of understanding of farmers in production and marketing activities.

Unbeabsichtigte Exposition gegenüber scharfen Instrumenten sind die häufigsten Arbeitsunfälle, an denen Fachkräfte und Studenten in einem Krankenhausumfeld beteiligt sind. Biologisches Material (MB) entsteht durch direkten Kontakt zwischen Blut und genitalen oder serösen organischen Flüssigkeiten mit ungesunder Haut, Schleimhäuten oder durch direkte perkutane Inokulation durch scharfe Gegenstände.Ziel dieser Arbeit war es, das epidemiologische Profil von Unfällen mit Exposition gegenüber biologischem Material zu charakterisieren, die bei Arbeitnehmern im brasilianischen Bundesstaat Amapá, Amazonas, im Zeitraum von 2015 bis 2019 aufgetreten sind, und die Anzahl, Art der Vorkommen, den Beruf und die Umstände zu analysieren des Unfalls. Eine retrospektive, deskriptive epidemiologische Querschnittsstudie wurde mit einem quantitativen Ansatz durchgeführt. So wurde die Datenbank des Informationssystems für meldepflichtige Krankheiten (SINAN) nach Aufzeichnungen durchsucht, die sich auf Meldungen von Unfällen mit biologischem Material beziehen, die im Bundesstaat Amapá im Zeitraum von 2015 bis 2019 aufgetreten sind und vom Arbeitsmedizinischen Überwachungszentrum registriert wurden ( NVST) / Referenzzentrum für Arbeitsmedizin (CEREST / AP). Die berufliche Exposition gegenüber biologischem Material birgt ein potenzielles Risiko für die Übertragung von Krankheiten. Die Anweisung der Arbeitnehmer, Unfälle unverzüglich zu melden, ist für die Bereitstellung des Benachrichtigungssystems von wesentlicher Bedeutung. In Bezug auf die Umstände waren die beiden am häufigsten festgestellten Ursachen nahe beieinander liegende Werte, die Verabreichung von Medikamenten (21,6%) und die unzureichende Entsorgung des Materials (20%). Diese falsche Entsorgung zeigt den mangelnden Eifer der Fachkräfte für ihre eigene Gesundheit.
Homeownership Rate and Other House Price Determinants
Impacts on New House Prices in Colombia
Authors: Botello-Peñaloza Hector
Published: March 2021

Homeownership remains a preferred form of tenancy in different parts of the world. The
attractions of security, stability, investment potential and a sense of pride outweigh the fear of
price instability. For this reason, the Colombian government has encouraged in recent years,
various demand policies that have sought to promote the increase in the number of homeowners.
However, these ideas could have a severe impact on prices in the real estate market. Therefore,
this study seeks to examine the effect of homeownership rate on new house prices in an emerging
country with low real estate ownership, credit restrictions and average per capita income. The
study uses panel data model to examine the influence of housing tenancy and other variables on
the variation of housing prices in Colombia. Data were obtained from various sources including
the Central Bank of Colombia, Financial Superintendence of Colombia, and National
Administrative Department of Statistics of Colombia. The results show that homeownership rates
have a positive effect on the price of new homes, which supports the hypothesis of the research.
The population growth of the cities is the factor that is most relevant when explaining the price
variations.
Examination of Social Justice Behaviors: Testing an Integrated Model
Authors: Hoang Tuyet Mai Ha , Neville Helen A. , Poteat V. Paul , Spanierman Lisa B.
Published: March 2021

In this study, we tested an integrated model of social justice behaviors among a community sample of 179 Asian American and White American adults. The integrated model builds on the theory of planned behavior (TPB) and sociopolitical development theory (SPD). Findings from path analyses provided partial support for the integrated model. Specifically, social justice awareness, subjective norms, and perceived behavioral control were uniquely and positively related to participants’ social justice intention. Intention to act, however, did not predict self-reported social justice behaviors. Multiple group comparison analyses suggested that the aspects of the integrated model consistent with the TPB were better supported in the White American sample, whereas the aspects of the model consistent with SPD were a better fit for the Asian American sample. Particularly, social justice attitudes were related to self-reported actions for Asian Americans in the sample, but not White Americans.

Розроблено модель життєвого циклу проєкту екологістичної системи, в якій відбито зв’язки між часовими інтерва- лами й притоками й відтоками грошових коштів, що відповідають етапам фаз життєвого циклу проєкту. Запропоновано математичну формулу для розрахунку дисконтованого строку окупності проєкту, яка враховує специфічні особливості формування потоків грошових коштів окремих фаз життєвого циклу проєкту екологістичної системи. Застосування формули можливе в разі виконання умови сталості потоків етапів експлуатаційної та регенеративної фаз, що відповідає умовам невизначеності під час прогнозування потоків грошових коштів на почат- ку проєкту. Висновки. Екологістична система має специфічні характеристики, що відрізняють її від логістичної системи. Зокрема, життєвий цикл проєкту екологістичної системи містить екологоорієнтовані фази, протягом яких здій- снюються заходи, спрямовані на збереження та відновлення екосистеми. Модель життєвого циклу проєкту екологістичної системи містить п’ять фаз: передін- вестиційну, інвестиційну, експлуатаційну, регенеративну й ревіталізаційну, що протікають упродовж шести часових інтервалів. Кожному часовому інтервалу відповідають потоки грошових коштів певних фаз. Представлено модель жит- тєвого циклу, яка враховує притоки й відтоки грошових коштів протягом часових інтервалів. Оцінка ефективності проєкту здійснюється за допомогою показ- ника дисконтованого строку окупності з урахуванням специфічних особливостей потоків грошових коштів упродовж життєвого циклу екологістичної системи.

Вступ. Натепер річкові інформаційні системи стали невіддільною частиною державної системи забезпечення безпеки судноплавства. Такі системи створю- ються на акваторіях морських портів і на підходах до них, а також на всій про- тяжності внутрішніх вод. Метою статті є аналіз стану й перспектив розвитку річкових інформаційних систем. Визначено сучасний стан і перспективи розвитку інфраструктури внутрішніх водних шляхів, що складаються з багатьох взаємо- пов’язаних факторів. Більшу частину чинників об’єднує необхідність підвищення безпеки судноплавства, яка своєю чергою виділяє ряд напрямів розвитку, з-поміж яких підвищення ефективності використання інфраструктури внутрішніх вод- них шляхів і вдосконалення системи управління судноплавством у цілому. Резуль- тати. Визначено систему обробки інформації про навігаційну обстановку, що є основою ключової концепції програмного модуля системи річкової інформаційної системи. Сформована основа для створення програмної компоненти інформацій- ної системи судноводія. У результаті проведених досліджень виявлено значення застосування річкових інформаційних служб на українських річках для інтенсив- ного розвитку ринку транспортних і логістичних послуг як України в цілому, так і окремих її регіонів. У статті визначено актуальність використання цифро- вого коносамента, що дасть можливість у реаліях, які склалися, відповідно до чинних обмежень, спричинених заходами щодо запобігання поширенню гострої респіраторної хвороби COVID-19, спричиненої коронавірусом SARS-CoV-2, змен- шити контакт та убезпечити членів екіпажу й приймальної сторони. Ство- рена автоматична система та її застосування на внутрішніх водних шляхах України дозволить полегшити роботу судноводія, зменшити кількість помилок. Характеризуючи обладнання, ми пропонуємо принцип такої структуризації, яка полегшить роботу такої системи в автономному режимі. Тобто визначено концепцію сукупної структури річкової інформаційної системи, що дасть мож- ливість безпечного проходження суден на внутрішніх водних шляхах і дозволить знизити вплив людського фактора на виконання навігаційних операцій. Висновки. Застосування річкової інформаційної системи спрямоване на убезпечення навіга- ційних операцій і підвищення ефективності вантажоперевезень завдяки постій- ному інформаційному контролю положення судна, місцеперебування стаціонар- ного й рухомого об’єктів.

Published: March 2021

Eleven rice hybrids including two check varieties were evaluated to approximate their genetic variability, heritability and genetic advance for ten quantitative traits. The analysis of variance illustrated that all the quantitative traits differed significantly indicating that enough variation is presenting the studied materials. Among the desirable quantitative traits number of filled spikelet’s per panicle was found to have highest both phenotypic and genotypic variance followed by total number of spikelet’s per panicle. Almost all the characters showed a little variation between PCV and GCV revealing little influence of the environment on the expression of traits. High phenotypic and genotypic variance coupled with high heritability and high genetic advance was observed for number of filled spikelet’s per panicle, total number of spikelet’s per panicle, plant height and number of unfilled spikelet’s per panicle. Such findings stipulated that these traits were governed by additive gene actions which are fixable and these traits may be accounted for reliable index of selection. The genotypes G3 (IR79156A × EL108R) and G6 (IR79156A × EL253R) were selected as high response superior promising rice hybrids for achievable yield advantage 49% and 23%, respectively over best check varieties. Therefore, the G3 and G6 are proposed to be extensively evaluated for further trial of variety release.

Authors: Akter S , Hossain MB , Akter S , Hasan T , Mahmud AU
Published: March 2021

Tomato Yellow Leaf Curl caused by Tomato Yellow Leaf Curl Virus (TYLCV) is one of the most important diseases of tomato causing heavy losses in yield and quality of fruits. Damage caused through phloem feeding and transmission of TYLCV by the insect vectors whitefly (Bemisiatabaci). In this study the competence of silver metallic plastic mulch, botanicals and insecticides were assessed to manage the Tomato Yellow Leaf Curl Virus (TYLCV) by controlling the insect vectors. In total 7 treatments including control were considered viz. T1=Imidacloprid, T2= ACmix, T3= Subicron, T4= Neemax, T5= Multineem, T6 = Silver metallic plastic mulch and T7= Control. All the treatments showed significant influence on different assayed parameters in the test crop tomato. The lowest disease incidence, disease severity and whitefly association was found in T6 treatment (silver metallic plastic mulch) that was 2.87%, 1.72% and 2.0% at 60 days after transplanting (DAT) respectively. While the highest disease incidence, disease severity and whitefly association were found in T7 treatment (control treatment) that was 14.71%, 46.22% and 18, respectively, at 60 DAT. From the relationship study between disease incidence and disease severity with whitefly association, it was revealed that disease incidence and severity of TYLCV was increased with increasing of whitefly population and vice-versa. Among the treatments, growth parameters, yield and yield attributers were also found better in T6treatment (silver metallic plastic mulch). Silver metallic plastic mulch is the best option to manage the TYLCV by controlling the insect vectors, whitefly instead of insecticides.

This paper has focused on seasonal variations of price and trend of the price escalation of paddy in Bangladesh using monthly average wholesale price of Boro paddy over a period from 2001 to 2019. Secondary data were used in this study and collected from different secondary sources. The multiplicative model was exercised in this study; the least square method was applied to find out the long-term changes occurring in the price of paddy and the ratio to moving average method was used to measure seasonal fluctuations in price of paddy. It was evidently observed from the study that seasonal fluctuations in price of paddy prevail in Bangladesh as seasonal indices were deviated from hundred in different months. April to August, the price of paddy was lower compare to other months’ price because April and Mayare the harvesting period of Boro paddy and resulted in more supply to the market. From August, it was increasing gradually and reached to the highest position on March with 112.15. Long-term trend analysis showed that prices of paddy will increase Tk. 72.80 per quintal higher annually compare to the country’s average price.

Published: March 2021

Population dynamics and infestation of fruit fly, Bactrocera cucurbitae Coquillett (Diptera: Tephritidae) was monitored on cucumber, Cucumis sativus using methyl eugenol trap during summer and autumn in 2017 at Gazipur, Bangladesh. Relationship between the abundance of fruit fly and meteorological factors was also studied. The fruit fly showed significantly higher abundance in summer compared to autumn. The larval population per fruit was found higher in summer (24.9 fruit-1) than that in autumn (1.5 fruit-1). The daily mean temperature had significant positive, light intensity had insignificant positive, relative humidity had insignificant negative and rainfall had insignificant negative correlation with fruit fly abundance. The temperature, light intensity, relative humidity and rainfall individually contributed to fruit fly abundance of 14.1 %, 24.0 %, 0.8 % and 1.8 %, respectively. The combined effect of the weather parameters on fruit fly abundance was 40.7 % and the equations were insignificant. The fruit fly showed significantly lower level of infestation in methyl eugenol treated plots as compared to controls in both summer and autumn.

Authors: Hendra Hendra
Published: March 2021

Leukemia Limfoblastik Akut (LLA) adalah penyakit keganasan yang diakibatkan oleh adanya mutasi somatik yang multistep  pada sel progenitor limfoid. Meskipun cukup jarang terjadi pada orang dewasa, namun risiko meningkat seiring usia. Sebanyak 20% kasus dari LLA adalah dewasa. Sebagian kasus muncul pada anak, namun kematian terjadi lebih banyak pada dewasa. Prognosis LLA pada dewasa tergantung dari subtipe nya dan dapat memburuk dengan cepat tanpa tatalaksana yang tepat. Dibutuhkan update pengetahuan baru tentang tatalaksana LLA yang relaps ataupun refrakter. Pada tahun 2017, US Food and Drug Administration menyetujui Inotuzumab Ozogamicin sebagai terapi baru untuk kasus LLA relaps atau refrakter pada dewasa.
