Full text linkThe general objective of the research is to obtain sustainable land recovery technology as aresult of intensive use of artificial chemical fertilizers. The specific purpose of this research is: a). a). Get the optimal dose of biophosphate fertilizer for the growth and yield of several varieties of peanuts, b). Get peanut varieties that have high productivity, c). Look at the interaction between bio-phosphate doses and peanut varieties. The study was conducted at the Lampung State Polytechnic Practice Garden from July to December 2017. The study was a factorial experiment in a randomized block design consisting of 2 factors. As the first factor is the dose of biophosphate fertilizer, namely: P0 = 0 kg/ha, P1 = 50 kg/ha, P2 = 100 kg/ha and P3 = 150 kg/ha. While the second factor is peanut varieties, namely: V1 = Gajah, V2 = Kelinci, and V3 = Takar, so that 12 treatment combinations are obtained. If there is a difference in the middle value, it is followed by a test of honest difference (BNJ) at the level of 5%. Based on the results of the study some conclusions can be drawn; (a) The provision of bio-phosphate treatment at a dose of 50 kg / ha gives the highest plant height compared to other treatments, while the Takar variety has a higher plant height compared to Gajah and Kelinci. (b) The provision of bio-phosphate treatment of 150 kg / ha gave the lowest yield of pods compared to 100 kg / ha and 0 kg / ha of bio-phosphate, while the Takar variety gave a better number of filled pods compared to Gajah and Kelinci. (c) The content of pods per plant gives the same results as the number of filled pods. Keywords : bio-phosphate, peanut, organic

Pengaruh Perlakuan Pupuk Organik dan Varietas terhadap Pertumbuhan dan Hasil Kedelai (Glycine max, L. Merr.)
Full text linkPermasalahan yang dihadapi dalam upaya peningkatkan produksi kedelai saat ini adalah kurangnya daya dukung lahan yang produktif. Hal ini disebabkan terjadinya degradasi serta kerusakan lahan akibat pola pertanian konvensional saat ini yang lebih mengutamakan penggunaan input tinggi seperti pupuk an-organik dan pestisida. Oleh karena itu, peningkatan produktivitas dan kualitas kedelai harus diupayakan dengan cara-cara yang lebih baik, seperti menggunakan pupuk organik. Sumber pupuk organik dapat berasal dari berbagai biomas atau bahan organik, seperti sisa tanaman atau hewan. Setiap bahan organik memiliki kandungan atau komposisi unsur hara yang berbeda-beda. Tujuan dari penelitian ini adalah mengetahui pengaruh penggunaan pupuk organik terhadap pertumbuhan dan hasil kedelai. Penelitian ini merupakan percobaan faktorial dalam rancangan acak kelompok, dengan 2 faktordan 12 perlakuan. Jika terdapat perbedaan nilai tengah dilakukan dengan menggunakan Uji Nyata Jujur (BNJ) pada taraf 5 % dan 1 %. Hasil penelitian menunjukkkan bahwa perlakuan pupuk organik, serta interaksi antara pupuk organik dan varietas tidak menunjukkan perbedaan yang nyata terhadap jumlah polong isi, jumlah polong hampa, berat polong isi dan berat biji pertanaman. Sedangkan perlakukan varietas menunjukkan perbedaan yang nyata terhadap jumlah polong isi, jumlah polong hampa, berat polong isi dan berat biji pertanaman. Varietas Detam memberikan jumlah polong isi, jumlah polong hampa, berat polong isi dan berat biji pertanaman lebih tinggi dibandingkan dengan varietas Anjasmoro dan Edamami.

Pelatihan Penanggulangan Hama Tanaman dengan Pestisida Nabati pada Kelompok Tani Reka Daya Bagelen Pesawaran
Full text linkProblems faced by the Reka Daya farmer group in Bagelen Pesawarant include: high production costs, especially for the purchase of fertilizers and anorganic pesticides. Generally, the plants cultivated are vulnerable to attack by plant pests (OPT), therefore integrated pest control technology is needed in plant cultivation. A participatory approach and adapted to site-specific conditions so that there is no surge in OPT attacks. The results of PKM that have been done based on questionnaire data and interviews that have been conducted can be concluded that; (a) members of the Raka Daya farmer group in Bagelen Pesawaran generally trying to work in agriculture with the main commodity of paddy rice; (b) 100% of farmers interviewed using anorganic pesticides in pest control; (c) 37% of participating farmers were familiar with plant-based pesticides, but overall none had used them in pest control; (d) After counseling and training in making organic pesticides, farmers are interested to try and implement it in the field
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
