Penelitian yang bertujuan untuk mengetahui produksi dan karakteristik kacang pinto (Arachis pintoi) yang diberi pupuk kandang sapi dan mikoriza serta kombinasinya dilakukan di rumah kaca menggunakan Rancangan Acak Lengkap pola factorial dua faktor. Faktor pertama adalah dosis pupuk kandang sapi (tanpa,10 ton/ha, 20 ton/ha dan 30 ton/ha). Faktor kedua adalah dosis mikoriza yaitu (tanpa, 10 g/pot, 20 g/pot dan 30 g/pot), dengan tiga kali ulangan. Hasil penelitian menunjukkan bahwa terjadi pengaruh nyata (P<0,05) interaksi antara pupuk kandang sapi dan mikoriza pada peubah kolonisasi akar. Perlakuan pupuk kandang sapi berpengaruh nyata (P<0,05) pada peubah berat kering batang, berat kering daun, berat kering akar, berat kering tajuk, dan jumlah bintil akar. Perlakuan mikoriza berpengaruh nyata (P<0,05) pada peubah kolonisasi akar. Berdasarkan hasil penelitian dapat disimpulkan bahwa interaksi antara perlakuan pupuk hayati mikoriza dengan pupuk kandang sapi berpengaruh pada peubah kolonisasi akar, perlakuan pupuk kandang sapi dosis 20 ton/ha meningkatkan berat kering daun, batang, tajuk, akar dan jumlah bintil akar sama dengan dosis 30 ton/ha, dan perlakuan pupuk hayati mikoriza dosis 20 g/pot menghasilkan kolonisasi akar paling tinggi.

Published: December 2019

<p>Klasifikasi adalah salah satu metode penting dalam kajian data mining. Salah satu metode klasifikasi yang populer dan mendasar adalah k<em>-nearest neighbor</em> (kNN). Pada kNN, hubungan antar sampel diukur berdasarkan tingkat kesamaan yang direpresentasikan sebagai jarak. Pada kasus mayoritas terutama pada data berukuran besar, akan terdapat beberapa sampel yang memiliki jarak yang sama namun amat mungkin tidak terpilih menjadi tetangga, maka pemilihan parameter k akan sangat mempengaruhi hasil klasifikasi kNN. Selain itu, pengurutan pada kNN menjadi masalah komputasi ketika dilakukan pada data berukuran besar. Dalam usaha mengatasi klasifikasi data berukuran besar dibutuhkan metode yang lebih akurat dan efisien. <em>Dependent Nearest Neighbor</em> (dNN) sebagai metode yang diajukan dalam penelitian ini tidak menggunakan parameter k dan tidak ada proses pengurutan sampel. Hasil percobaan menunjukkan bahwa dNN dapat menghasilkan efisiensi waktu sebesar 3 kali lipat lebih cepat daripada kNN. Perbandingan akurasi dNN adalah 13% lebih baik daripada kNN.</p><p><em><strong>Abstract</strong></em></p><p class="Abstract"><em>Classification is one of the important methods of data mining. One of the most popular and basic classification methods is k-nearest neighbor (kNN). In kNN, the relationships between samples are measured by the degree of similarity represented as distance.

Sorting phase of kNN becomes a computation problem when it is done on big data. In the effort to overcome the classification of big data a more accurate and efficient method is required.

Bilateral Porokeratosis Ptychotropica on the Gluteal Cleft: A Case Report and Review of the Literature
Authors: Nazarian Roya S. , Vyas Nikki , Scheinfeld Noah , Phelps Robert G. 
Published: December 2019

Porokeratosis ptychotropica (PP) is a rare variant of porokoretosis that is distinctive based on its clinical presentation of pruritic, verrucous papules and plaques that often form a “butterfly” shape, commonly located on the perinatal cleft with extension to the buttocks. Similar to other variants of porokeratosis, it is histologically distinguished by the presence of cornoid lamellae. Proper diagnosis is necessary as some studies suggest that PP may predispose to squamous cell carcinoma. Furthermore, there are limited evidence-based treatment options.We report the case of a47 year-old-male who presented with a rash on the buttocks and legs for 3 years. Physical exam revealed erythematous, annular, and verrucous plaques on the bilateral periglueteal area and bilateral distal lower extremities. The patient felt that lesions on the legs were disfiguring but otherwise asymptomatic. Biopsy results demonstrated hyperkeratosis and parakeratosis suggestive of cornoid lamellae. Clinical and histologic findings were suggestive of PP. Lesions on the legs were treated with cryotherapy, which resulted in resolution at a 3-month follow-up.PP remains a diagnostic and therapeutic challenge due to its rarity. No standard of care has been established, though topical calcipotriol, topical imiquimod, topical tretonoin, and cryotherapy have been used with success in the literature. This case highlights unique characteristics of PP in order to aid in early detection and cancer prevention while also describing various treatment modalities.

Published: December 2019

Autoimmunity Related Neutrophilic Dermatoses (ARND) is a recently described entity characterized by urticarial papules and plaques with histology showing a neutrophilic perivascular and interstitial infiltrates with leukocytoclasis, along with variable vacuolar interface dermatitis. We report a 38 year old Caucasian female with a ten year history of lupus who presented with pruritic urticarial papules and plaques on the face, trunk, upper extremities and thighs. The onset occurred 10 days after she started a calcium channel blocker (CCB), diltiazem. Histopathology revealed scattered dyskeratotic keratinocytes, vacuolar interface dermatitis, and a sparse perivascular and interstitial mixed infiltrate of neutrophils within the dermis. There was focal leukocytoclasis, dermal edema, and rare eosinophils. The patient initially improved with prednisone taper, but flared again upon starting a different CCB, verapamil. Exposure to certain medications such as CCB in the setting of autoimmune connective tissue disorder may be the inciting trigger for a neutrophilic dermatoses. Future studies may provide further information on the pathogenesis of ARND and cutaneous drug eruption in the setting of SLE.

In this 21st century education, preparing learners to have high order thinking skills (HOTS) is important to make them ready face the global era. HOTS (analyze, evaluate, create) is the continuous phases of LOTS (remember, understand, apply). HOTS in a project based instruction is proposed to be able to promote the skills needed in the 4.0 era (critical thinking, communication, creativity, and collaboration). This research focused on a HOTS-based project in a mechanical engineering, Adisutjipto College of Technology. Based on the observation in the previous semester, the students needed to improve their HOTS that the research applied an action research study. The projects were allocated in two course objectives; identifying the tools in mechanical engineering and identifying the components of an airplane. They were chosen due to the supported authentic materials exist in the college workshop laboratory, hangar, and airplane museum near the college. The results were the learners enjoyed the learning and improved the engagement in a group work, the critical thinking in finding fruitful information, the creativity in creating presentation, and the speaking skill in presenting in front of other people.
KAJIAN KARAKTERISTIK ALIRAN TERHADAP BANGUNAN PELIMPAH PADA SALURAN TERBUKA
Authors: Saleh Syam Sunniati , Musa Ratna , As'ad Hanafi 
Published: December 2019

Pelimpah (Spillway) merupakan salah satu bangunan pelengkap dari bendungan yang berfungsi sebagai pengaman terhadap bahaya air banjir yang melimpas diatas bendungan (overtopping). Selain itu, bangunan pelimpah juga berfungsi agar debit hujan rancangan yang terjadi cepat mengalir sehingga debit air tidak sempat meluas. Karakteristik aliran yang melewati bangunan pelimpah akan tergantung kepada bentuk dan sifat pelimpah itu sendiri. Untuk kepentingan bangunan air seperti bendungan dan bangunan air lainnya maka perihal karakteristik aliran sangatlah penting untuk menentukan bangunan yang akan dipilih sesuai kebutuhannya. Pengkajian tentang hal ini dapat dilakukan melalui suatu penelitian terhadap aliran pada saluran terbuka berukuran kecil yang melewati pelimpah dengan model bangunan pelimpah type ogee. Adapun tujuan dari penelitian ini yaitu untuk mengetahui karakteristik aliran, pola aliran dan energy spesifik yang terjadi pada bangunan tersebut. Pada penelitian ini dapat disimpulkan bahwa aliran air dapat mengalami perubahan ketinggian karena adanya bangunan pelimpah dan berpengaruh pada karakteristik alirannya. Dimana semakin tinggi muka air maka semakin besar kecepatan yang terjadi.Pola aliran pada daerah hulu merupakan aliran sub kritis (FR1) kemudian menjadi kritis (FR = 1) pada saat melewati bangunan pelimpah. Setelah melewati bangunan pelimpah maka aliran menjadi super kritis (FR 1) dan berangsur-angsur menjadi normal kembali pada saat berada di daerah hilir.Energi spesifik yang dihasilkan pada bangunan pelimpah tipe Ogee juga bergantung pada jenis pelimpah yang diberikan.
Artifact Biography: A Variable Colour Mixer
Authors: Weidenhammer Erich 
Published: December 2019

Among the artifacts representing early research in experimental psychology at the University of Toronto is a precisely machined steel instrument of German manufacture. The provenance of this variable colour mixer opens onto a largely-forgotten history of research into colour perception that depended heavily on mechanical instruments of the spinning-wheel type. Like the broader practices and principles of experimental psychology, these instruments were widely disseminated during a period in which the German research-based model of university education was widely admired. For most of its early history at the University of Toronto, the experimental laboratory was run by a German, August Kirschmann (1860-1932), who led investigations into the psychological basis for aesthetic judgement, especially as it concerned colour perception. Kirschmann’s hostility to existing art criticism reflected his belief that experimental psychology could provide a coherent foundation to the language of aesthetics.

Вершины экономической мысли конца прошлого столетия. По мотивам книги Ю. П. Воронова «Нобелевские лауреаты по экономике (1997–2018)»
Authors: Клисторин В. И. 
Published: December 2019

<span>Эта статья не является в полном смысле рецензией на книгу Ю. П. Воронова. Скорее это размышления о современном состоянии и тенденциях развития экономической науки, ее лидерах и аутсайдерах, языке науки и способах представления результатов. Отталкиваясь от текстов упомянутой книги, хочется ответить на ряд вопросов. Прежде всего, в какой мере обоснованны и насколько субъективны решения Нобелевского комитета при присуждении премий? Сюда примыкает вопрос о степени идеологизации и политизации экономической науки вообще и научного истеблишмента в частности. Показано, что, несмотря на значительные усилия по формированию подлинно объективной экономической науки, лишенной ценностных и идеологических моментов, устранить их не удается. Экономисты пересматривают микроэкономические основы макроэкономической теории и уделяют большее внимание функционированию институтов и их влиянию на экономическую политику, экономический рост и дифференциацию благосостояния. Карьере ведущих ученых немало способствовало совмещение академической деятельности с практической работой и публицистикой.</span>
