Use Potential of Local Propolis Extracta as Halal Biocoating on Storage of Domestic Chicken Eggs Biocoating at Room Temperature
Get PDFEggs are livestock products which contribute significantly to the fullfil nutrition need of community, because of one egg contains nutrients is complete and easy to digest. However, eggs have a short shelf life and only lasted 10-14 days at room temperature. This research aims to develop a preservation method of egg which efficient and halal. In this research, egg of domestic chicken (Gallus sp.) was coated with propolis extract of Trigona sp. Propolis extracted with two methods which were ethanolic extraction followed with aquadest extraction prior to application. Propolis extract applied by immersed egg inside propolis extract for 15 seconds, 30 seconds 45 seconds and 60 seconds with eggs without any coating designated as control. Eggs were kept in room temperature and change in egg quality (e.g. shape index, shell thickness, height of air cell) measured at 0, 7, 14, 21 and 35 days after the immersion. In the same time, alcohol content were tested with ester formation and Iodoform test. The results showed that propolis coating did not effect shape index, however maintained good shell thickness and height of air cell. Furthermore alcohol test did not showed sign of alcohol all treatment groups. Based on this study, it could be concluded that application of propolis extract as egg coating may increase egg shelf life while comply with halal regulation
UPAYA PENINGKATAN PENDAPATAN PETANI YANG MAKSIMAL MELALUI PENGATURAN POLA PEMILIHAN KOMODITAS MODEL SINERGI: Studi Kasus di Kecamatan Cibiru Kota Bandung
Get PDFPenelitian untuk mengetahui mengetahui seberapa besar pendapatan
petani dapat ditingkatkan dengan mengoptimalkan pola tanam komoditas melalui
model konfigurasi usaha tani sinergi yang sesuai dengan posisi lahan, kemampuan
daya dukung dan daya tampung lahan telah dilaksanakan pada petani anggota
Koperasi Mahesa Biru, Kecamatan Cibiru Kota Bandung dari bulan Juli hingga
November 2005. Penelitian menggunakan metode survey deskriptif dengan teknik
analisis sebab akibat dan analisis manfaat biaya. Analisis dilakukan untuk
mendapatkan gambaran akar masalah yang dihadapi petani dan menghitung
kelayakan ekonomi komoditas yang potensial untuk dioptimalkan sehingga
memberikan nilai ekonomi yang lebih baik. Hasil analisis menunjukkan bahwa
petani masih menghadapi masalah dalam permodalan, harga jual komoditas yang
ditanam tidak sesuai dengan biaya pokok produksi dan akses pemasaran yang
terbatas sehingga tergantung pada bandar. Sehingga keuntungan atas hasil usaha
taninya terbatas. Dengan menggunakan pendekatan pemodelan usaha tani
dengan Pola Konfigurasi Spesifik (PKS), pendapatan petani diprediksikan dapat
meningkat hingga hampir 6 kali lipat dari kondisi awal.
Kata Kunci : usaha tani pola konfigurasi spesifi

The study on Work Load Calibration by using Step Test and Ergometer test was carried out in order to find the best way 10 calibrate the data measurement and to predict human work load by using heart rate data. This study was conducted on four male subjects. but the data analysis has just been done to three subjects due one of the subject was insufficient performance. The sport tester PE3000 heart rate monitor is used for measuring the heart rate data which will be useful for predicting the work load on each activity. The linear regression method is also used to predict the work load based on the heart rate data, so that the best alternative scenario data input will be able to determined by comparing the correlation coefficient or coefficient of determination.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Get PDFPenelitian untuk mengidentifikasi umur kematangan buah manggis telah dilakukan dengan menggunakan pendekatan identifikasi melalui pengolahan citra (image processing) berdasarkan fitur warna RGB (red, Green, Blue). Dari hasil penelitian yang telah dilakukan di laboratorium Sistem dan Manajemen Keteknikan Pertanian UNPAD diketahui adanya kendala dalam pengklasifikasian berdasarkan fitur RGB terutama dalam menyusun kisaran kelas kematangan. Untuk mendapatkan gambaran efektifitas dalam menentukan kelas kematangan buah manggis tersebut dilakukan penelitian lanjutan dengan menggunakan beberapa metode klasifikasi, antara lain metode crisp, metode fuzzy dibandingkan dengan metode pengklasifikasian cara manual. Penelitian dimaksudkan untuk melihat efektifitas pengklasifikasian kematangan buah manggis berdasarkan analisis kinerja perangkat lunak pengolah citra fitur RGB yang ada dengan membandingkan ketiga metode pengklasifikasian tersebut. Berdasarkan hasil uji keragaman data diketahui bahwa metode crisp dan metode fuzzy keduanya layak untuk digunakan namun metode crisp memiliki hasil yang lebih baik karena mendekati standar pengujian dengan cara manual. Kapasitas pengklasifikasian buah manggis dengan menggunakan metode crisp adalah 1,092 detik/buah, metode fuzzy 1,144 detik/buah, dan manual 2 detik/buah. Sehingga dari ketiga metode tersebut, metode crisp memiliki hasil yang terbaik untuk digunakan dalam klasifikasi buah manggis dengan perangkat lunak yang ada.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
