Model Simulasi Pertumbuhan dan Produksi Tanaman Tebu
Full text linkTo reduce the level of difficulty conducting research in complex systems, modeling is defined as simplification of system with mechanistic approach, can be an alternative approach for understanding and prediction ecophysiology process of growth, development and production plants. Modeling the growth of sugarcane crop is expected to be used as a tool to predict the production of sugarcane production as well as in a development area. Research purposes that make simulation model of sugarcane growth and development develop the tools in an effort to plan and optimize the productivity of sugarcane and sugar productivity predicts. The experiment was conducted in Kotabumi of Lampung regency. Began in June 2008 ended in July 2009. Research materials in the form of climate data for 2 years (2008 to 2009), soil data, the data accumulation, and agronomic data. Tool in this study the precipitation gauge type observatory, TL-1 Illuminance meter to measure the radiation coming, belgi drill, sample
ring, digital scales and oven. Research using analytical methods or simulation models of plant
systems are supported field trials. The model is built based on the variables and parameters
obtained from secondary data as well as from experiments. Construction of a simulation
model of sugarcane growth and development has been able to simulate and describe the
development and growth of sugarcane as shown by the results of field observations. The
simulation results for the production of sugarcane harvested biomass ± 100 ton/ha while the observation of ±85 ton/ha (the simulation results have to be in the range of values one standard deviation from the average). Phenological period and the prediction accuracy of the simulation results are relatively consistent with the observation field (simulated total biomass production 115 ton/ha while the observation of 101 ton/ha)

Efisiensi Penggunaan Cahaya Matahari oleh Tebu pada Berbagai Tingkat Pemupukan Nitrogen dan Fosfor
Full text linkLight use efficiency is a crucial parameter in plant growth associated with accumulation of energy interception. Nitrogen and phosphorus deficiency reduce leaf area index (LAI) and specific leaf nitrogen and phosphorus (SLN and SLP) content and reduce efficiency of light intercepted by plant canopy structure. This research was conducted in Kebun Bunga Mayang PTPN VII, North Lampung Regency, Lampung Province (04050’S, 104052’E, 38 m above sea level) from July 2008 to September 2009. Treatments were distributed in the field under a randomized complete block design factorial with three replications. The increase in nitrogen fertilizer (N) improved sugarcane light use efficiency. The light use efficiency of the sugarcane plants fertilized with 225 kg N ha-1 was 2.29 g MJ-1 at maximum stem phase. On the contrary, the increasing of phosphor (P) fertilizer did not affect light use efficiency but increased stem dry matter at maximum seedling phase or about 3 month after planting (3 MAP), at maximum stem phase (9 MAP), and at harvest (11 MAP); total dry matter at seedling phase (5 MAP) and at maximum stem phase (9 MAP). Nitrogen did not interact with P in affecting light use efficiency. Keywords: fertilization N and P, interception radiation, light use efficiency, sugarcan
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
Tingkat Frekuensi Penyiraman dan Waktu Aplikasi Pupuk Phonska Terhadap Pertumbuhan Dan Hasil Cabai (Capsicum annum L.)
Full text linkThis research aims to find out the frequency level of watering and application time of Phonska fertilizer as well as its interaction towards the growth and chili (Capsicum Annum L.) Yields. This research is conducted at Agry Green, department of agro technology, faculty of agriculture, State Universitas of Gorontalo form August to Desember 2019, applying factorial group randomized design consisting of 2 factors. The first factor is the level of watering frequenty comprising of 2 levels: one time of watering and twi times. The second factor is the application time of Phonska fertilizer comprising of 3 levels: one time of application on 1 MST (300kg/ha) = 2,25g/polybag, two times of application on 2 and 4 MST (150+150kg/ha)= 1,125g/polybag, three times of application on 2, 4 and 6 MST (100+100+100kg/ha)= 0,75g/polybag. The data are analyzed with analysis of variance and continued with the Least Significant Difference on the test level of 5%. The findings reveal that the frequency level of watering does not have significant influence towards the growth and chili yields. The different application time of Phonska fertilizer does not have significant influence towards the growth and chili yields. The best result is obtained on the frequency level of watering at 07.00 in the morning and one application time of Phonska fertilizer with a dose of 300kg/ha
