Indonesia‘s Refining Developments: Future Prospects and Challenges
Authors: Rahman Maizar
Published: February 2022

Since 1994 Indonesia has not built any new refineries due to the economic crisis in1998, which was followed by political reform. Last year Indonesia had imported more than400 thousand bpd (barrel per day) of petroleum products. On the supply side, Pertamina’srefinery capacity of 1,050 thousand bpd produces only up to 750 thousand bpd of petroleumfuels or 68 % of domestic consumption.A study has been conducted on the refining development in Indonesia up to year 2030.According to a projection based on reference scenario, in year 2030 Indonesia will consume2.60 million bpd of petroleum fuels. If security of supply approach is taken intoconsideration, Indonesia will require 3 million bpd of total refinery capacity. New refineriesproducing additional 2 million bpd have to be constructed in order to fulfill domesticdemand for petroleum fuels. The additional new refineries would then be on-stream one byone with 300 thousand bpd of capacity starting from year 2015, and would be built nearconsumers’ area or close to the existing refineries.As the margin of new refinery is not high enough, appropriate strategies such as optimumconfiguration, synergy to utilize possible supporting resources should be taken intoconsideration, while Indonesian government should also offers better incentives in orderto make the project economically feasible.
SOME APPROACHES TO TEACHING LEXICAL COLLOCATIONS (illustrated by everyday and sport collocations)
Authors: Bazyliak Natalia , Matviyas Olha
Published: February 2022

The present article deals with the word combinability and the importance of word co-occurrence while learning the English language. The importance of a word comprehension not as a separate lexical unit but as a part of a phrasal item is recognized in many scientific articles written by Richards, J. and Schmidt, R., Willis D., Mackin, R., the latter being broadly cited in a great number of modern student books focused on the methods of English language teaching. While designing Students’ English Books and the authors, those who are not English native speakers, pay little attention to such an important point as word collocations. This leads to poor results when learners are to take the examination in English as a foreign language or write a test to obtain a certificate of a corresponding level. The authors have analyzed the available Pupil’s books designed for pupils of Ukrainian secondary schools and recommended by the Ministry of Education of Ukraine. Among them there are books issued by both national publishers and foreign ones. Some samples of tests were analyzed as well as the authentic texts taken from the Internet resources, newspapers and journals. The article contains some useful tips for teachers of English as a foreign language. For those who are going to study English independently, we offer some approaches to mastering the vocabulary using the available printed and  e-dictionaries.
CROSS-CULTURAL DIFFERENCES BETWEEN AMERICANS AND UKRAINIANS
Authors: Koliada Elina , Kalynovska Iryna
Published: February 2022

This article considers cross-cultural communication between Americans and Ukrainians. Its purpose is to stress how Americans and Ukrainians think and express their thoughts, how they act interpersonally, and how they follow the many hidden rules that govern conduct. In today’s world, it is both valuable and necessary to be aware of intercultural differences. Cross-cultural communication refers to the communication between people who have different cultural backgrounds. Misunderstandings and problems between them primarily occur because they assume that what is natural, appropriate, and acceptable for them must be natural, appropriate, and acceptable to others. Different cultural assumptions may underlie different views on what is “polite” or “rude.” The authors draw attention to the most apparent and fundamental areas of cultural understanding breakdowns, which exist at the everyday level of life between native speakers of American English and Ukrainian. They point out that it is not enough to learn the language’s vocabulary and grammar to understand and be understood by native speakers. The mentality and world view of native speakers is crucial in choosing to use a particular word and the cultural context. The article covers the most basic discourse areas where breakdowns often occur in intercultural communication. They are: addressing people, meeting someone new, meeting and parting etiquette, and receiving guests.

Published: February 2022

In this article, the process and results of a literature search using a new proposed scientific literature search tool (ToS: Tree of Science) aimed at partially overcoming the need to search in different databases was used. In its present form, ToS needs, as input, a previous search in the Web of Science (WoS), and by means of all references used in the articles found in the WoS search, it selects the more significant items, classifying them into three categories: root, trunk and leaves. In our example, from an initial total sum of 164 hits found in WoS, ToS provided 90 items. The following fields of these two results were put together in an Excel sheet for elimination of repetitions and further consideration: title, authors, source, year of publication and DOI (Digital Object Identifier). Then, the titles of the articles were read and graded by the three authors (a senior researcher, a junior researcher, and a PhD student) as 0 (of no interest for the topic), 1 (of possible interest) or 2 (of interest). The marks were added up and those with a score > 3 (56) were selected for the abstracts to be read by the PhD student to establish a final student’s own selection (SoS) of articles for initiating the review of the literature on her topic of interest.

Perkembangan tampilan gedung-gedung baru di lingkungan Universitas Mataram satu dekade terakhir menampakkan adanya pergeseran ke arah bentuk dan material kekinian yang menghasilkan fasad/tampilan sangat berbeda dengan gedung-gedung yang ada sebelumnya. Hal ini menghadirkan kekhawatiran bila dibiarkan berkelanjutan maka Universitas Mataram sebagai salah satu perguruan tinggi negeri di Nusa Tenggara Barat akan kehilangan jati diri atau identitasnya.  Penelitian ini bertujuan untuk mengkaji ciri atau kriteria arsitektur vernakular dan ramah lingkungan yang dapat diterapkan pada gedung kampus Universitas Mataram dan mengevaluasinya pada gedung lama dan gedung baru. Penelitian ini menggunakan metode kualitatif, dengan mengkaji literatur dan mengevaluasi bangunan berdasarkan kriteria yang didapatkan. Gedung perpustakaan mewakili gedung lama dan gedung Fisipol mewakili gedung baru sebagai gedung-gedung yang dikaji. Analisis data dilakukan secara deskriptif kualitatif. Hasil menunjukkan bahwa gedung perpustakaan dan Fisipol memenuhi kriteria atau ciri arsitektur vernakular yang sama walau secara visual keduanya tampak berbeda. Akan tetapi, gedung perpustakaan memenuhi kriteria arsitektur ramah lingkungan lebih banyak dibandingkan dengan gedung Fisipol yang merupakan bangunan baru. Kajian ini diharapkan dapat meningkatkan penelitian arsitektur vernakular sebagai identitas kampus-kampus baru di Indonesia. Penelitian ini masih banyak kekurangan sehingga membutuhkan lebih banyak kajian yang serupa.

The organization itself has a membership structure that functions to divide the tasks of each individual and each organization has a leader who functions to regulate the running of the organization. At XYZ University, there are various organizations that all students can participate in. The head of the organization is chosen from the election activities held every year to continue the baton of management. There are several obstacles experienced when conducting election activities, namely, election activities are carried out offline, due to pandemic conditions so that election activities cannot be carried out, there are many invalid ballots, and also the vote-counting process which takes quite a long time. In addition to obstacles during the election, election activities also cost quite a lot to print ballots and so on to launch elections. Therefore, this research was conducted by building an e-voting information system. The e-voting system itself has several advantages compared to elections conducted offline. It is hoped that the e-voting system can reduce errors made in offline elections. The system development uses the Personal Extreme Programming (PXP) method using the Laravel framework.

Phosphazene-containing oligomers (FEO) were synthesized by the one-pot method by reacting hexachlorocyclotriphosphazene, diphenylolpropane, and epichlorohydrin at 80 °C in the presence of solid KOH. In contrast to analogous oligomers previously obtained at a lower temperature, according to MALDI-TOF spectrometry data, they contain about 10% of compounds with two or three phosphazene rings linked by one or two oxyaryleneoxy radicals, while the total number of epoxy groups in the molecules of these compounds is from 4 to 8. FEO are cured with polyamine hardeners to form compositions with increased fire resistance, retaining at the same time the basic properties of conventional epoxy materials.
