Authors: Kinasih Norma Arisanti , Cifriadi Adi 
Published: December 2020

Hasil penelitian pendahulan diketahui bahwa penggunaaan minyak jarak pagar epoksi memiliki kompatiblitas yang baik dengan vulkanisat karet NBR dan mampu menggantikan pelunak dioktil flalat (DOP). Kompatibilitas yang baik, serta besarnya peluang pasar minyak nabati epoksi yang mencapai 50 ribu ton per tahun maka perlu dilakukan upaya untuk memproduksi minyak jarak pagar epoksi dalam skala lebih besar. Pada penelitian ini akan digunakan hasil percobaan laboratorium sebagai acuan peningkatan skala produksi minyak jarak pagar epoksi. Proses produksi peningkatan skala dilakukan dengan sistem batch. Penelitian ini mendeskripsikan mengenai kondisi dan karakteristik produksi tahap peningkatan skala (rendemen produksi), kualitas produk yang dihasilkan serta stabilitas kualitas produk selama masa penyimpanan 1 bulan di suhu ruang. Peningkatan skala menghasilkan rendemen minyak jarak pagar epoksi murni sebesar 65,11% dan nilai oksiran sebesar 1,43%. Kestabilan mutu produk epoksi selama 1 bulan penyimpanan cenderung tidak stabil. Hasil analisa statistik menunjukkan bahwa proses produksi sistem batch dan penyimpanan selama 1 bulan berpengaruh signifikan terhadap mutu produk epoksi.

Tingginya keragaman ditingkat progeni membuat para pemulia karet dituntut lebih teliti dalam melakukan seleksi awal calon genotipe baru. Beberapa parameter seperti karakter pertumbuhan tanaman, anatomi dan fisiologi lateks mempengaruhi produksi karet. Penelitian ini bertujuan untuk mengetahui keragamaan ditingkat progeni dan mengetahui karakter yang berpengaruh langsung terhadap daya hasil karet pada populasi hasil persilangan antara PB 260 dan RRIC 100. Hasil penelitian menunjukkan bahwa progeni hasil persilangan antara PB 260 dan RRIC 100 mempunyai tingkat keragaman tinggi pada daya hasil, kadar sukrosa, kadar fosfat anorganik, dan jumlah pembuluh lateks, sedangkan lilit batang, tebal kulit, dan kadar tiol mempunyai keragaman yang rendah. Lilit batang dan tebal kulit batang berkorelasi nyata terhadap daya hasil. Namun berdasarkan analisis regresi bertatar, hanya lilit batang yang mempunyai pengaruh langsung terbesar terhadap daya hasil pada progeni hasil persilangan PB 260 x RRIC 100, sedangkan parameter lilit batang dan kadar tiol mempunyai pengaruh langsung terbesar terhadap daya hasil pada progeni hasil persilangan RRIC 100 x PB 260.

Salah satu alternatif untuk meningkatkan pendapatan petani karet adalah adanya komoditas pendukung yang diusahakan secara mix-cropping dengan tanaman karet. Pola usahatani berbasis karet telah diusahakan petani di Sumatera Selatan selama bertahun-tahun. Salah satu lokasi di Provinsi Sumatera Selatan yang mengusahakan tanaman sela sebagai sumber pendapatan tambahan adalah Desa Pangkul di Kota Prabumulih. Penelitian ini bertujuan menampilkan gambaran mengenai usahatani karet dengan tanaman sela dan pendapatan yang diperoleh dari pengusahaan pola usahatani ini. Metode yang digunakan dalam pengambilan data melalui diskusi langsung dengan kelompok tani yang beranggotakan 23 orang dengan didampingi oleh perangkat desa dan petugas Penyuluh Pertanian Lapangan (PPL). Hasil penelitian menunjukkan bahwa petani di Desa Pangkul pada umumnya telah mempunyai minat dan motivasi yang kuat untuk menerapkan teknologi anjuran. Hal ini terlihat dari produksi tanaman karet yang cukup tinggi serta input yang diberikan pada tanaman karet dan tanaman sela sudah sesuai dengan anjuran. Tanaman sela yang umum diusahakan petani meliputi tanaman sayur-sayuran dan bibit karet. Tanaman sayur-sayuran dapat dipanen dalam waktu singkat sehingga pengusahaannya dapat dilakukan secara intensif. Pada umumnya tanaman sela diusahakan selama tiga tahun masa tanaman belum menghasilkan (TBM). Rata-rata pendapatan usahatani dari tanaman sela adalah Rp 7 juta per bulan. Pendapatan yang diperoleh dari tanaman sela cukup tinggi terutama dari tanaman tomat kecil yaitu sekitar 67% dari total pendapatan usahatani.

Published: December 2020

Stimulan merupakan salah satu upaya meningkatkan produksi lateks pada tanaman karet. Penggunaan stimulan tanpa memperhatikan karakteristik klon menyebabkan kelelahan fisiologi. Penelitian ini bertujuan mengetahui pengaruh konsentrasi stimulan terhadap fisiologi lateks pada beberapa klon. Penelitian ini dilakukan di Kebun Percobaan Balai Penelitian Sungei Putih di areal plot promosi (PP/07/03) Tahun Tanam 2004. Rancangan Petak Tersarang digunakan dalam penelitian ini dengan perlakuan pertama adalah jenis klon (IRR 412, IRR 417, IRR 420, IRR 406, PB 260 dan BPM 24). Perlakuan kedua adalah konsentrasi stimulan terdiri dari tiga taraf yaitu S0 (tanpa stimulan), S1 (ethepon 2,5%), dan S2 (ethepon 5%). Hasil penelitian menunjukkan peningkatan konsentrasi stimulan dapat meningkatkan produksi, kadar thiol dan kadar fosfat anorganik, tetapi menurunkan kadar karet kering, dan kadar sukrosa. Indeks penyumbatan sangat nyata dipengaruhi oleh konsentrasi stimulan dan interaksi antara klon dan stimulan. Dari keenam klon yang diuji, klon IRR 412, IRR 406, dan BPM 24 tergolong responsif terhadap stimulan, sementara klon IRR 417, IRR 420 dan PB 260 kurang responsif.

Published: December 2020

Tujuan dari penelitian ini adalah menganalisa linkages dan dampak industri karet alam terhadap perekonomian daerah Jambi. Jenis penelitian ini adalah penelitian kuantitatif. Data yang digunakan dalam penelitian ini adalah data Sistem Neraca Sosial Ekonomi (SNSE) Provinsi Jambi tahun 2015. Metode penelitian ini adalah dengan mendisagregasi matriks SNSE dari ordo 52x52 menjadi 55x55 dengan mendisagregasi sektor perkebunan menjadi 4 sektor, yaitu industri ban; industri karet remah dan karet asap; industri barang-barang lainnya dari karet; dan industri kayu, barang dari kayu, dan lain lain. Hasil temuan menunjukkan bahwa industri karet primer maupun hilir berperan signifikan terhadap perekonomian Provinsi Jambi, yaitu sebesar IDR 29,86 Trilliun atau 69,17% dari nilai tambah faktor produksi di Provinsi Jambi dan penyerapan tenaga kerja sebesar 630 ribu orang atau 40,2% dari jumlah tenaga kerja di Provinsi Jambi. Hasil temuan menunjukkan bahwa forward dan backward linkage dari semua industri karet primer dan dua jenis industri karet hilir (industri karet remah dan karet asap; dan industri kayu, barang dari kayu dan lain lain) memiliki forward linkage < 1 dan backward linkage >1 sehingga hanya efektif sebagai leading sector saja. Perubahan yang terjadi di sektor lain atau menggunakan pembangunan sektor lain tidak akan efektif untuk mendorong pertumbuhan keempat subsektor industri karet tersebut. Sektor industri karet primer dan dua jenis industri karet hilir tersebut akan tumbuh jika sektor itu sendiri yang ditumbuhkan. Dari aspek penggandaan pendapatan secara total, subsector perkebunan karet memiliki penggandaan pendapatan total yang tertinggi. Dengan demikian, untuk meningkatkan pendapatan pada agisbisnis karet secara keseluruhan, maka pemilihan pembangunan fokus di subsector perkebunan karet merupakan kebijakan yang strategis dan prioritas karena penggandaan pendapatan totalnya yang tertinggi (1,35) disusul oleh perkebunan selain karet (1,28); industri kayu, barang dari kayu (1,17) dan industri karet remah dan karet asap (1,09). Kebaruan penelitian ini adalah secara spesifik mendisagregasi sektor perkebunan karet menjadi subsubsektor perkebunan karet yang lebih rinci.
Glycemic Control and Risk of Cellulitis
Authors: Zacay Galia , Hershkowitz Sikron Fabienne , Heymann Anthony D. 
Published: December 2020

OBJECTIVE
We know that diabetes predisposes to common infections, such as cellulitis and pneumonia. However, the correlation between the level of glycemic control and the rate of infection is unknown.

RESEARCH DESIGN AND METHODS
We examined the association between glycemic control in patients with diabetes and the incidence of infection in the entire population of patients with diabetes in a large HMO. During the study period, we first selected an HbA1c test for each patient and then searched for an infection diagnosis in the 60 days that followed the test. A multivariate logistic regression analysis was performed to determine the independent effect of HbA1c on the likelihood of being diagnosed with an infection. We were able to control for many confounders, such as other chronic illness, time since the diagnosis of diabetes, and use of steroids before the infection.

RESULTS
We identified 407 cases of cellulitis. Multivariate logistic regressions for cellulitis showed a 1.4-fold increased risk among patients with HbA1c &gt;7.5% (58 mmol/mol). Factors such as obesity, Parkinson’s disease, peripheral vascular disease, and prior treatment with prednisone predisposed to cellulitis. There was an increase of 12% in the odds of cellulitis for every 1% (11 mmol/mol) elevation in HbA1c (odds ratio [OR] 1.12; CI 1.05–1.19). A similar analysis showed a trend toward an increased risk of pneumonia in patients with HbA1c &gt;7.5% (58 mmol/mol) (OR 1.1; CI 0.9–1.4).

CONCLUSIONS
Poor glycemic control was associated in this study with the development of cellulitis. The study also suggests that exposure to oral prednisolone increases the risk of cellulitis, pneumonia, and upper respiratory infection.
The Institution and Practice of Zemsky Sobors: the Experience of Political and Romantic Construction in the Political History of Russi
Authors: Chernyakhovsky Sergey F. , Chernyakhovskaya Julia S. 
Published: December 2020

The article is devoted to the overview and understanding of the phenomenon of Zemsky Sobor in the Russian state, – the representative body of power in the 16-17 centuries, -that became the first Russian parliament and determined the history of Russian parliamentarism for nearly 500 years. The authors assess the scope of their authority form the point of view of the political science, and show their functional significance and role in Russian history in the process of transformation of Russian national state during the reign of Ivan the Third into the multinational Empire of Peter the Great. The importance of this research is dictated by the tasks of modern Russian parliamentarism that needs to ensure adequate representation of political, social and socio-cultural groups of Russian society, on the one hand, and by the nearly coinciding in dates two anniversaries: the 25th anniversary of the state Duma of the Russian Federation and the 470th anniversary of the opening of the first Zemsky Sobor (February 27–28, 1549), on the other hand.
The Year of 1905 and Zemsky Sobor
Authors: Lukoianov Igor V. 
Published: December 2020

The article is devoted to the discussion of the plans for convening the Zemsky Sobor (representative body of the Estates of the Empire) in the first half of 1905 in Russia. Despite the fact that for the beginning of the twentieth century, this form of class representative body was deeply archaic, there were heated debates in the society and among the top leaders about the possibility of returning to the Zemsky Sobor to solve many acute problems, and above all, – whether to pursue the war against Japan. However, after intensive discussions by the summer of 1905 the autocracy rejected the idea of the Sobor, preferring the State Duma to it. It seems that as regards to the Sobor, the imperial power, not accepting the uncompromising position of the ultra-right, did not have the chance to gain the support and sympathy of the liberals in the case of the convening of the Zemsky Sobor.
Russian Conservatism and Popular Representation
Authors: Ulyanova Lyubov V. , Mezhuev Boris V. 
Published: December 2020

The article is devoted to the issue of Russian conservatism and popular representation and analyzes the new historiography of social thought in the end of the 19th and beginning of the 20th centuries on the basis of a number of monographs and materials of well-known specialists in late Slavophilism published by the “Russian Idea” internet site over the period of several years. The authors differentiate the protective conservatism (in the spirit of K.P. Pobedonostsev and his work “The Great Lie of Our Time”) that denied the positive role of any representation, and the social conservatism that saw the popular representation in the form of Zemsky Sobor as an integral part of political life and panacea against revolution. The authors prove the thesis that moderate conservative and Slavophiles’ recipes of social and political system modernization, based on the principles of power and society mutual trust, much better suited the goals of Russian state system evolutionary modernization than the reactionary protective conservatism on the one hand, and western liberal parliamentarism, on the other hand.
Sovietism. Who Defends the Rightness of the Cannibal
Authors: Yuriev Dmitry A. 
Published: December 2020

Sovietism means the betrayal of the memory of the Immortal regiment, the substitution of the trench truth with the osobist’s lie, the revenge of the osobists over trench fighters. Legalization of ignorance. Legalization of evil. This is the shameless attempt to justify Stalin by Hitler, mass terror – by the Holocaust. This is a direct threat to everything that we have in life and to everything that can still come true. A threat to the preservation of people, a threat to the revival of Russia.
Two Fates: “Russkaya Beseda” and “Russky Vestnik” (to the Question of the Reasons for the Failure of the Slavophil Publishing Project)
Authors: Perevalova Elena V. 
Published: December 2020

The article provides a comparative analysis of two Moscow literary and political magazines of the second half of the 1850s: “Russkaya Beseda”, the publication of which was initiated in 1856 by members of the Moscow Slavophile circle A.I. Koshelev, Yu.F. Samarin, Aksakovs, I.V. and P.V. Kireevsky and others, and the “Russky Vestnik”, which arose in the same year as an organ of a pro-Western liberal university professors. It was revealed that in a very favorable socio-political situation (liberalization of the government course, the rapid development of public thought, the weakening of censorship), both publications were able to successfully implement their programs and gain recognition from an educated audience. However, while “Russky Vestnik” quickly became one of the leaders in Russian periodicals, the publication of “Russkaya Beseda” was discontinued by 1860 due to the small number of subscribers. We consider the factors that led to the success of the publication of Westerners and became the cause of the failures of the Slavophile magazine: frequency, efficiency, informational and thematic diversity, especially the relationship with censorship bodies, etc.
Admiral A.S. Shishkov: the Forerunner of the Slavophiles
Authors: Grebenshchikov Alexander E. 
Published: December 2020

The Slavophile trend of Russian socio-political thought was formed in the middle of the 19th century. The Slavophiles A. Khomiakov, brothers Kireevsky and Aksakovy, Ju. F. Samarin believed that Russia had differed fundamentally from the West, so the European path of development was disastrous for it. Admiral A.S. Shishkov was among those who anticipated these ideas. In the article the author examines the similarities and differences in the views of the admiral and the Slavophiles and reviews the main events of A.S. Shishkov’s life.
“I Don’t See Any Reason for Changing My Opinion”: F.D. Samarin About Zemsky Sobor and the Concept of Representation
Authors: Marey Maria D. 
Published: December 2020

The present article is devoted to the study of political views of one of the representatives of late Slavophilism – F.D. Samarin. The author mainly focuses on Samarin’s attitude to the idea of Zemsky Sobor that was very popular in Russian public circles in the beginning of the 20th century, and on his views on the possibility of the introduction in Russia of a representative body, even if only of deliberative nature. That issue was very important for Samarin as Slavophile, as he’d accumulated great experience of practical work in Zemstva. The author shows the sources of Samarin’s skepticism regarding the concept of representation and turns to the analysis of his own reformative ideas that he offered as alternatives to constitutional reforms and introduction of a new law-making deliberative body. The author pays special attention to Samarin’s attitude to the autocratic monarchy and his belief that the monarch could grant various freedoms to his subjects (freedom of religion, freedom of press, freedom form administrative and police despotism) while still remaining autocratic and not restricting his power by adopting constitution and formation of the Parliament.
Yu.F. Samarin, M.P. Pogodin, S.P. Shevyryov and the Ideas of Nationality
Authors: Logvinova Irina V. 
Published: December 2020

. In the article the author analyzes the contribution of the three prominent representatives of Slavophilism, – Yu. F. Samarin, M.P. Pogodin and S.P. Shevyryov, – to the development of the concept of “narodnost” (nationality). Special attention is paid to the development of the nationality concept in science and the role of this factor in the historic development of Russia. Reflecting upon the idea of popular principles, the Slavophils arrived at the conclusion that nationality (“narodnost”) was not only the condition of successful development of the state, but also the condition of the successful progress of the science.
A Synopsis of Online Testing Integrity in a General Education Math Course: A Correlational Study
Authors: Howard Daris William 
Published: December 2020

Online education is expected to grow, bringing new challenges. One of the biggest challenges concerns the validity of online assessments. Questions arise about cheating, including whether or not the person taking the assessments is the student registered for the course. Studies have tried to determine the amount of cheating in online assessments using student self-reporting. Concern about the validity of these studies has led to quantitative studies attempting to determine the level of cheating in online classes by comparing unproctored online classes against proctored classes. This quantitative quasi-experimental study uses such an approach, comparing test scores and the amount of time online unproctored students spend on exams against test scores and the amount of time spent on exams by students proctored in a testing center and by students proctored online using software. The data for each of the three groups, online-unproctored, testing-center-proctored, and software-proctored, were collected for each of the three unit exams, with data samples over 1,000 for each group on each test. The means of the exam scores of the unproctored online students were similar to the means of the exam scores of the other two groups, but the means for the amount of time the unproctored online students spent on the exams were significantly greater than were the means of the time spent by students in the either of the other two groups. The increased amount of time spent by the unproctored students likely indicated students looked up answers during the tests.
IMPLEMENTASI THEORY OF PLANNED BEHAVIOR (TPB) PADA PENGUKURAN PERSEPSI PENDAPATAN BUNGA BANK KONVENSIONAL
Authors: Dewi Liana , Lestari Puji 
Published: December 2020

Pengetahuan mengenai haramnya riba tengah berkembang pesat di masyarakat. Berdasarkan pada pengetahuan tersebut masyarakat terdorong untuk melakukan berbagai usaha dalam menghindari riba salah satunya adalah dengan menghindari penerimaan bunga bank dari simpanan dananya di bank. Penelitian ini bertujuan untuk mempelajari faktor-faktor yang mempengaruhi niat serta tindakan masyarakat dalam menghindari pendapatan bunga bank dengan menggunakan Theory of Planned Behavior (TPB) sebagai dasar teori. Sampel dalam penelitian ini berjumlah 55 responden yang berasal dari komunitas bebas-riba. Data dikumpulkan melalui kuisioner yang terdiri dari 20 pernyataan dan dianalisis dengan Structural Equation Model (SEM). Hasil pengujian menyatakan bahwa sikap berpengaruh negatif terhadap niat individu untuk menghindari pendapatan bunga bank sementara norma subjektif berpengaruh sebaliknya, persamaan dari keduanya adalah pengaruhnya yang kurang kuat. Kontrol keperilakuan yang dipersepsikan memiliki pengaruh positif dan kuat terhadap niat, sama halnya dengan niat yang mempengaruhi tindakan penghindaran individu terhadap pendapatan bunga bank.
