This study aimed to explain the valence of Malay verbs in the Akit dialect of Padang island, Regency of Kepulauan Meranti. The method used was qualitative descriptive. The data was collected using the equivalent method and the observation method. The data used were oral and collected using interviews, observation, and intuition methods. The data analysis was used to split, deletion, substitution, and expansion techniques. The results of the data analysis were explained using the informal method. The results showed that Malay people on this island used the Malay language daily. Accordingly, the valence of the verbs found in the conversations of the Malay people on the island of Padang was one valence of verbs, two valences of verbs, and three valences of verbs. Through the passivation process, the three kinds of valence of the verbs could be derived from two valences of verbs became one and from three valences of verbs became two. One-valence verbs were bound by only one argument. Verbs with two valences were bound by two arguments at once, while verbs with three valences were bound by three arguments, while the process of decreasing valence could be done by passivation.

Library is an important part of the public cultural service system. Library policy is a major force that can not be ignored. As the carrier of cultural inheritance, library plays an important role in cultivating and practicing core values and promoting civilized practice in the new era. Excavating the theme of the library is the basis for determining the development and service direction of the library. The library policy is facing difficulties such as unclear construction direction and inadequate guidance. Under this background, the research on China’s library policy is carried out. With the library as an example, the topic mining and quantitative analysis of library policies in the eastern, central, and western regions of my country from 2011 to 2020 were conducted using the LDA topic model. Meanwhile, the differences between the three regions were investigated. The results demonstrate that: (1) In terms of quantity, policy texts in the eastern region account for more than half of them; (2) Regarding keywords, high-frequency words mainly include culture, openness, and information in the eastern region, numbers, resources, and reading in the central region, and students, teaching, and learning in the western region; (3) The hot topics in the eastern region involve library government affairs, library digital resources, and library service mode, that is, strengthening the construction of library digital resources and improving service level with an open attitude; (4) The hot topics in the central region contain library management, library student training, and library security, suggesting that the aspects of internal management and system security are emphasized to train students and guide the modernization of the library; (5) The hot topic in the western region includes the construction of two libraries in one station for library evaluation management and library procurement, implying to promote library reform from the bottom up and make crucial arrangements for creating a new situation for grass-roots libraries. On this basis, the policy support of government departments for library development in the future should focus on formulating regulations and rules under the Library Law, establishing a dynamic balance between supply and demand, and enhancing exchanges and cooperation between libraries in the east, middle, and west.

<p>Turbin gas merupakan salah satu penggerak mula siklus terbuka dengan bahan bakar berupa minyak bumi, gas alam ataupun campuran antara minyak bumi dan gas. Dalam perkembangannya turbin gas dapat dibuat dalam skala mikro dengan membalik prinsip <em>turbocharger</em> menjadi turbin gas mikro. Penelitian ini meliputi pengujian turbin gas mikro atau <em>micro gas turbine</em> (<em>MGT</em>)<em> </em>yaitu menggunakan 2 <em>turbocharger </em>yaitu 1 sebagai turbin gas penggerak kompresor (<em>high pressure turbine</em>) dan 1 turbine gas penggerak generator arus searah (<em>low pressure turbine</em>). Dalam penelitian ini menggunakan 1 ruang bakar dengan desain tertentu. Tujuan dari penelitian ini adalah membandingkan dan meneliti hasil pengujian langsung pada mesin dan simulasi penggunaan perangkat lunak untuk memberikan gambaran fundamental tentang permodelan kinerja turbin gas mikro. Metode penelitian yang digunakan adalah menggunakan metode kuantitatif berupa pengambilan data besaran fisik temperatur dan tekanan dengan pengujian langsung pada mesin menggunakan <em>turbocharger</em> DH 300-7 untuk turbin kesatu dan PC 200-8 untuk turbin kedua. Karena tumpuan poros menggunakan bantalan luncur (<em>journal bearing</em>) maka <em>MGT</em> dapat dilakukan dengan pengujian putaran turbin kesatu sebesar 16.000 rpm, pengujian kedua menggunakan putaran 20.000 rpm dan terakhir 25.000 rpm. Dalam penelitian ini hasil uji performa <em>MGT</em> dimasukkan dalam perangkat lunak <em>Thermoflow</em><em>, </em>untuk memberikan gambaran fundamental tentang permodelan kinerja <em>MGT</em> lebih lanjut. Ditarik kesimpulan bahwa semakin tinggi putaran akan menghasilkan daya yang meningkat, tekanan dan temperatur pada sisi keluar kompresor semakin meningkat, tekanan dan temperatur pada sisi keluar dari ruang bakar semakin meningkat serta tekanan dan temperatur keluar dari turbin 1 meningkat juga temperatur keluar dari turbin 2 meningkat. Berlaku tren peningkatan tekanan pada lokasi pengamatan pada setelah keluar kompresor dan pada ruang bakar serta sedikit menurun akibat kehilangan tekanan (<em>pressure drop</em>) di tengah ruang bakar dan menurun setelah keluar turbin 1 dan keluar turbin 2. Tren temperatur secara umum meningkat dari keluar kompresor, ruang bakar, turbin ke 1 dan menurun sebelum masuk dan keluar turbin 2. Terjadi perbedaan antara hasil pengukururan langsung dan simulasi menggunaan perangkat lunak yaitu karena pengukuran langsung hanya mengukur kondisi fisik diluar (<em>casing</em>) mesin secara manual dan kondisi lingkungan yang berubah-ubah, berupa angin, kelembaban. Kondisi mesin berbeda saat pengujian 16.000 rpm mesin cenderung lebih dingin dibanding 20.000 rpm dan 25.000 rpm, kehadiran oli pendingin mesin serta desain ruang bakar. Untuk simulasi perangkat lunak menggunakan perhitungan berulang berupa iterasi menggunakan persamaan matematika secara ideal dan bersifat numerik serta kemungkinan adanya asumsi yang tidak pasti.</p>

The relevance of integrating massive open online courses (MOOCs) into foreign language teaching in higher education is explained not only by the modern approach to the digitalization of the educational environment, but is also a necessary measure in the light of the unfavorable epidemiological situation in Russia associated with the spread of a new coronavirus infection (COVID-19).The classification of MOOCs by purpose, principle of construction and format of training is given. The advantages and the disadvantages of MOOCs from the point of view of teachers are considered. The results of the integration of MOOCs into foreign language teaching to students of a range of engineering specialities are presented.Experimental work has identified the advantages of MOOCs associated with an unlimited resource base, a variety of tasks and access to authentic information.The disadvantages of MOOCs in teaching a foreign language concern the difficulties caused by the pedagogical imperfection of the format for evaluating the work of students on the course. A number of problems are associated with the lack of the necessary competencies of teachers, resource consumption when choosing a MOOC, corresponding to the level of language training of students.The authors propose ways to solve the problems that arise in the implementation of a mixed model of teaching a foreign language at universities, including the combination of traditional and online forms of monitoring learning outcomes.
