Klasifikasi Online dan Google

The purpose of this paper is to examine challenges facing bibliographic classification at both the practical and theoretical levels. At the practical level, libraries are increasingly dispensing with classifying books. At the theoretical level, many researchers, managers, and users believe that the activity of “classification” is not worth the effort, as search engines can be improved without the heavy cost of providing metadata

Penggunaan Media, Bahan Stek, Dan Zat Pengatur Tumbuh Terhadap Keberhasilan Stek Masoyi (Cryptocarya Massoy (Oken) Kosterm)

Masoyi (Cryptocarya massoy) merupakan salah satu jenis tanaman penghasil hasil hutan bukan kayu (HHBK) endemik Papua bernilai ekonomi tinggi. Upaya pengembangan tanaman masoyi saat ini terkendala oleh sulitnya memenuhi kebutuhan bibit dalam jumlah banyak dan berkualitas. Untuk itu, perbanyakan secara vegetatif menjadi salah satu solusi permasalahan pemenuhan bibit. Penelitian bertujuan mendapatkan media tanam, bahan stek, dan dosis zat pengatur tumbuh NAA yang tepat untuk perbanyakan masoyi dengan cara stek. Penelitian menggunakan bibit berumur 1 tahun dengan Rancangan Acak Lengkap Faktorial. Faktor pertama adalah media tanam stek (tanah+pasir (2:1, v/v), serbuk sabut kelapa+ sekam (2:1, v/v), dan media pasir). Faktor kedua adalah bahan stek (bagian pucuk atas dan bagian pucuk bawah). Faktor ketiga adalah konsentrasi zat pengatur tumbuh (0 ppm, NAA 500 ppm, dan NAA 1.000 ppm). Hasil penelitian menunjukkan bahwa persen berakar dipengaruhi oleh faktor tunggal media tanam, bagian stek dan zat pengatur tumbuh NAA. Panjang akar dipengaruhi oleh faktor tunggal media tanam dan interaksi antara media dengan bagian stek. Jumlah daun dipengaruhi faktor media tanam, sedangkan jumlah akar tidak dipengaruhi masing-masing faktor tunggal dan interaksinya. Faktor media merupakan faktor penentu keberhasilan stek masoyi. Dengan demikian, kombinasi media tanah+pasir (2:1, v/v) dengan bagian pucuk atas merupakan perlakuan yang direkomendasikan untuk stek masoyi, dan kombinasi perlakuan tersebut tidak dipengaruhi oleh zat pengatur tumbuh NAA

Pengaruh Suhu dan Waktu Ekstraksi terhadap Kafein dalam Kopi

This study was conducted to determine the effect of temperature and time on the acquisition of caffeine content in coffee by UV-Vis Spectrophotometry method. The study was conducted in the AKAFARMA Laboratory of YHB Banda Aceh and the Chemical Laboratory of FMIPA Unsyiah. The sample in this study is Arabica coffee powder produced by Solong Ulee Kareng which was intentionally taken. The results showed that based on temperature, the lowest caffeine content was found at 50 °C immersion temperature, which was 0.0275 mg/g and the highest level was at 100 °C soaking temperature, which was 0.181 mg/g. Whereas, based on the time when the highest caffeine content is found at 1 hour immersion at 50 °C was about 0.0675 mg/g, at 1 hour immersion at 70 °C was about 0.0862 mg/g, and at 1 hour immersion at 100 °C was about 0.181 mg/g. The temperature and extraction time have influenced on caffeine levels in Arabica coffee. The longer the time and the higher the extraction temperature, the more extracted caffeine could be found

On an Average Goldbach Representation Formula of Fujii

Fujii obtained a formula for the average number of Goldbach representations with lower order terms expressed as a sum over the zeros of the Riemann zeta-function and a smaller error term. This assumed the Riemann Hypothesis. We obtain an unconditional version of this result, and obtain applications conditional on various conjectures on zeros of the Riemann zeta-function.Comment: 17 page
