Karakterisasi Kapsul Keras Berbahan Gelatin dan Karaginan Hasil Hidrolisis Rumput Laut dengan Kapang
No full textKapsul komersial umumnya diproduksi dari gelatin babi atau sapi, namun
memiliki kendala berkaitan dengan aspek keamanan dan kehalalan. Karaginan
dapat digunakan sebagai bahan substitusi dalam pembuatan kapsul. Karaginan
komersial dihasilkan dengan ekstraksi secara kimiawi dan enzimatis, namun hasil
yang diperoleh belum efisien sehingga dapat dilakukan ekstraksi secara biologis
menggunakan kapang. Oleh karena itu, perlu dilakukan karakterisasi karaginan
hasil ekstraksi secara biologis menggunakan kapang serta mengkaji pengaruh
substitusi karaginan pada gelatin terhadap karakteristik kapsul yang dihasilkan.
Karaginan pretreatment perebusan memiliki karakteristik yang telah memenuhi
standar FAO dan BSN kecuali kadar air dan kadar sulfat sehingga dapat
digunakan sebagai bahan substitusi dalam pembuatan kapsul. Level substitusi
karaginan 0%, 5% dan 10% merupakan formula terpilih dalam pembuatan kapsul.
Karakteristik kapsul yang dihasilkan diantaranya panjang body 16.99±0.15 mm,
17.35±0.07 mm, 17.88±0.02 mm, panjang cap 6.30±1.12 mm, 8.10±0.90 mm,
6.37±0.80 mm, bobot 0.96±0.12 g, 0.99±0.12 g, 1.01±0.07 g, waktu hancur
kurang dari 30 menit, sedangkan kadar air kapsul 2 dan 7 belum sesuai standar
yang ditetapkan
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
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
Pemberdayaan Ibu-Ibu untuk Mengoptimalisasikan Lahan Pekarangan Rumah Desa Banjaran
Get PDFThe yard optimization program can have two benefits at the same time, namely increasing the economic value and the value of food security. The purpose of this activity is to socialize to the community the importance of optimizing the plot of land to increase economic value and food security on a family scale. The method used in this activity is a lecture followed by a question and answer session, in the last session there was a distribution of vegetable seeds such as tapai that can be planted in the family yard. The results of this day\u27s activity the community, especially housewives, understood the importance of optimizing the family yard by growing it with various kinds of family needs such as vegetables and family medicinal plants. .

Coastal Clean Up dalam Upaya Meningkatkan Kesadaran Masyarakat untuk Menjaga Lingkungan di Wilayah Pesisir Desa Sangrawayang, Sukabumi
Get PDFKabupaten Sukabumi is one of the regencies in West Java which is directly bordered by the Indian Ocean in the south. Simpenan District, especially Sangrawayang village has many natural attractions, one of which is Loji beach. The existence of tourism triggers a lot of garbage, especially plastic. The Coastal cleanup program is expected to be a means to provide education to surrounding communities to maintain the cleanliness of the environment, especially the coastal environment. This program consists of two programs, namely beach cleaning and waste identification. The waste identification program was carried out on July 2 and July 8, 2019, in Cibutun Hamlet. The waste identification activity was carried out in 2 replications and spread in 10 stations. The results of identification on the first and second tests show that the sequence of waste from the highest to lowest amounts are wood, plastic, fabric, rubber, glass, and metal.

Pengembangan Usaha Mikro Kecil Menengah Berbasis Agribisnis di Desa Paseh Kidul, Kecamatan Paseh, Kabupaten Sumedang
Get PDFThe Community Service program is a form of concern from institutions, especially the Bogor Agriculture Institute, for the people of Indonesia. The concentration of IPB in general is in the development of the agricultural sector especially Agribusiness for Sumedang Regency. Therefore, in 2019 one of the community service programs was carried out in the Paseh Kidul Village, which was expected to show the contribution of students in empowering local resources in increasing the potential of agriculture, the economy, animal husbandry, and existing human resources. This activity aims to optimize the economic potential, human resources, and natural resources, especially in the development of agribusiness-based Micro Small and Medium Enterprises. The products that have been produced will later be able to develop into MSMEs, so that hopes for the future can create jobs and can improve people\u27s welfare.
