Reiterating Indonesian National Identity in the Globalized World through a New Romantic Movement
Authors: Jatmiko Rahmawan
Published: June 2019

This article discusses the possibility of re-evoking and invigorating romantic spirits to reiterate Indonesian national identity. This commences from the fact that despite its comparatively young age, Indonesia has experienced a number of heroic and romantic struggles, notable in our national history; for instance, the “national awakening movement” Boedi Oetomo in 1908, which became the first modern symbol of national struggle in Indonesia, the Sumpah Pemuda in 1928, which instilled in the youth's mind the three factors in common as our national identity, which binds our multi-cultural existence and experiences i.e. the unity of territory, language, and nation; and the third is Indonesian Declaration of Independence, 17th of August 1945. This study starts from the assumption that those three symbols of struggle and identity are imprinted with romantic spirits, i.e. the sentimental feelings and emotions, which are no longer dealing with the worldly and materialistic considerations. In this discussion, one might question whether Indonesia has ever experienced any romantic movement as what European countries and America had in the end of the 18th century, yet that might not be so critical question in this case. Instead, what might be considered more important is another question such as, “do we need that kind of movement nowadays in order to clearly pronounce our identity?” By careful readings, observations and interpretations based on historiography and other references, this article sees that an attempt to give birth to our own Romanticism might be feasible as a good solution to rebuild our nationalism, since it also deals with recognizing and recalling our lost identity.
American Studies in Indonesia: Global or Local Content?
Authors: Inkiriwang Riani E. , Inkiriwang Alfred F.I
Published: June 2019

The curriculum of the American Studies Program at The School of Strategic and Global Studies of the University of Indonesia comprises among others conversations on American Philosophy, American Democracy, American Culture, American Politics, American Media and American Foreign Policy. An overall perspective of the discourse is to obtain the knowledge and the competence to critically analyze and abstract the role and influence of the United States in contemporary global as well as local affairs. However, in today’s multi-media culture, concerns arise whether the curriculum is still appropriate to fulfill the above goals. Our paper discusses these issues in looking at what to include in an American Studies curriculum that would address its local stakeholders needs and wants, including Indonesia’s vision of Higher Education, which is “to support the competitiveness of the nation.” (DIKTI,2015) In the American Studies context, a tension though might arise when the issues important to American Studies scholars in the USA, which we content are reflected in the themes of the American Studies Association’s 2017 and 2018 Annual Meetings, “Pedagogies of Dissent” and “State of Emergence” respectively, are blended into one local, i.e. Indonesian curriculum. We will explore the global, the main issues in the two above ASA conference themes reflecting “the contemporary theorization of American Studies scholars” and the local, American Studies curriculum’s stakeholders’ concerns. The results it is hoped will provide a discourse to be discussed among stakeholders of the American Studies curriculum in general, and this conference in particular.
Indonesian Intangible Cultural Heritage: Uniting Millennial Vernacular Literature and Global Awareness
Authors: Putri Widyarini Susilo
Published: June 2019

The millennial generation is said
as a threat as well as an opportunity to preserve the intangible cultural
heritage such as vernacular literature as national identity literature. To
unravel this problem, this paper use Theory of Generational Difference. This
theory is used to understand the existence of millennial generations more fully
and comprehensively. Because they are assets, not threats. Preserving the
Vernacular Literature as Indonesian intangible Cultural Heritage is not
properly enough to corner the millennial generation with a series of sentences polished
with theory and study. Tactical steps are needed to address this phenomenon.
Therefore, this research was conducted in several stages, namely; first,
outlining vernacular literature as intangible cultural heritage should be
preserved. Second, describing and analyzing the existence of the millennial generation
as prospective Indonesian literary relay holders using theory of generational
difference. The result then leads to a step of transformation to preserve
vernacular literature by increasing global awareness in in the praxis form.

Making global knowledge accessible to EFL speakers of an undergraduate leadership program through a flipped and ubiquitous learning environment
Authors: Tanaka-Ellis Nobue , Sekiguchi Sachiyo
Published: June 2019

This paper reports on how an undergraduate global leadership course was designed and implemented at a Japanese mid-sized private university to match the Japanese government’s initiative of fostering global individuals through education. By incorporating a flipped learning approach (Bergmann & Sam, 2012) and the content materials from a Massive Open Online Course (MOOC), the university was able to offer a global leadership program to Japanese students with some “hidden” English language assistance. The language support was provided by employing Content and Language Integrated Learning (CLIL), a pedagogical approach that is gaining global popularity (Coyle, Hood, & Marsh, 2010). Flipped learning was introduced to maximise the face-to-face class time for the activities to enhance active learning. Content learning was designed to be done online, before coming to every class. In order to support flipped learning and CLIL, ubiquitous learning was also incorporated to the program design. This paper also focuses on capturing the leadership program and develop the understanding of roles of each stakeholder by mapping human and nonhuman actors to see what resources were involved in manifesting this highly complex learning environment. The student perception on the leadership program was compared through interviews conducted in Weeks 4 and 14, to see if the program was successfully perceived as a leadership program, or perceived as just another English language program. Some implications of designing this type of multifunctional course are discussed to conclude the paper.
Insights from replication on the factors affecting task engagement in mobile-based learning activities
Authors: Stockwell Glenn
Published: June 2019

Despite the large amount of research that has taken place with mobile devices for language learning over the years, there are still limited conclusions that can be reached as to what contributes to sustained task engagement. A common problem that has long been seen in the CALL literature is that many tasks and activities that are reported are small scale studies taking place in a single environment with a limited number of subjects, often as a result of teachers investigating the outcomes of their own teaching (see Warschauer, 1997; Hubbard, 2005). Given the nature of the environments in which many teachers find themselves, it is in some way inevitable that studies tend to be of a smaller scale and often undertaken within a single class. It is possible to gain deeper insights into the tasks used through replication studies (Porte, 2012). This paper discusses the potential insights gained from replicating approximately the same basic language learning tasks in varied contexts. Research on vocabulary and listening tasks was carried out in Japan over an 8-year period from 2010 through 2017 for Japanese learners of English. In addition, the same tasks were adapted for Australian learners of Japanese in 2012 and Taiwanese learners of English in 2013, with a total of 420 participants. Data were collected through post-treatment surveys, semi-structured interviews and server logs recording the times spent on the tasks, the scores achieved, and the devices used to engage in the tasks. The same methods of data collection were used in each of the studies, using primarily the same tasks apart from adaptations made for developments in technology and for the different language learning contexts. Carrying out the same tasks in subsequent years with increasingly newer technologies and with teachers and learners from different cultural backgrounds provided insights into the effect of the context, the technology, and role of both teachers and learners in successfully implementing the tasks.

The Growth of Staphylococcus aureus in the blood agar plate media of sheep blood and human blood groups A, B, AB, and O
Authors: Turista Dora Dayu Rahma , Puspitasari Eka
Published: June 2019

BAP media is a medium used to distinguish pathogenic bacteria based on their hemolytic power on red blood cells. Staphyllococcus aureus is a bacterium that is able to emolate red blood cells with 3 types of hemolysis, namely α, β, γ, and δ. Usually BAP media is made by adding 5-10% sheep blood. Making BAP media using sheep blood has become a problem for several laboratories today, including health education laboratories. This is because the health education laboratory does not yet have a sheep farm, so it has not been able to procure sheep blood. The use of human blood as a substitute for sheep blood in making BAP media may be a solution, but it is not yet known whether there are differences in the growth and hemolysis of S. aureus bacteria on BAP media in sheep's blood and human blood. This research is an experimental study with a completely randomized design (CRD) of 3 replications which aims to determine whether there are differences in growth and hemolysis of bacteria S. aureus in BAP media of sheep blood and human blood groups A, B, AB, and O. The results showed that S. aureus bacteria could grow and show hemolysis in BAP media in sheep blood and human blood in groups A, B, AB, and O. The results of subsequent studies analyzed ANOVA using the software spss for windows with a significant level of 0.05. From the results of research and data analysis it can be concluded that S. aureus bacteria can grow and show hemolysis in BAP media of sheep blood and human blood groups A, B, AB and O, but there are significant differences in the number of S. aureus bacteria colonies grown in BAP media of sheep's blood and human blood groups A, B, AB and O.

La región del Totonacapan, entre los límites del norte de Puebla y Veracruz, produce 80% de la vainilla en México, y es considerada el centro de origen de la especie Vanilla planifolia Jacks. Sin embargo, la superficie sembrada ha disminuido, lo que afecta la competitividad del sector. En el presente trabajo se realizó una caracterización socioeconómica de los productores de Vanilla planifolia Jacks, durante 2017 y 2018 y se determinó el potencial productivo para el cultivo en la región del Totonacapan, mediante el empleo de sistemas de información geográfica (SIG) basado en factores edafoclimáticos y fisiográficos. resultados muestran que la producción es una actividad económica secundaria, entre productores de más de 55 años y en situación de minifundio. El potencial productivo más alto se localiza al noroeste de la región del Totonacapan y está condicionado por el incremento en las precipitaciones del mes más seco (abril: <60 mm año-1) y temperaturas no mayores a 30 °C en el trimestre más caluroso (junio-julio-agosto). Estas áreas están destinadas en su mayoría a la ganadería y agricultura de cultivos cíclicos más rentables, por lo que en la expansión del cultivo se deben considerar los aspectos socioeconómicos de los productores.

Se presentan los resultados del efecto del ácido salicílico (AS) en la absorción nutrimental de Capsicum chinense. Se asperjó 1 μM de AS, al dosel de plántulas de chile habanero y agua destilada como control. Los resultados obtenidos demuestran que aspersiones de 1μM de ácido salicílico(AS) incrementa significativamente la longitud, peso freso y peso seco de raíces, tallos, hojas y frutos de esta especie, al igual que los niveles de nitrógeno (N), fósforo (P) y potasio (K) en los diferentes órganos de las plantas al momento de la cosecha. La acumulación de N, P y K fue superior en frutos (116, 110 y 97%), hojas (45.5, 39.4 y 29.1%) raíz (52.6, 17 y 29.4%) y en tallo (5, 39.4 y 28.3%) sobre los valores de la planta control. Los niveles de cobre, zinc, manganeso, hierro, boro, calcio y magnesio también fueron incrementados en la mayoría de los tejidos por el efecto del AS. Se propone que el efecto positivo del AS de incrementar el tamaño de las raíces favorece la absorción y acumulación de macro y micronutrientes en los tejidos de la planta.

Published: June 2019

El uso de híbridos trilineales en los programas de mejoramiento genético de maíz (Zea mays L.) se ha incrementado en las últimas décadas, ya que cuenta con la ventaja de obtener mayor rendimiento de grano causado por la heterosis. El modelo AMMI (efectos principales aditivos e interacciones multiplicativas) ha evidenciado su capacidad para el análisis de la estabilidad, la adaptación y la interacción genotipo por ambiente (IG*A). El objetivo de esta investigación fue determinar la estabilidad y la IG*A del rendimiento de 25 híbridos de maíz amarillo evaluados en cinco ambientes de Perú, entre los años 2014-2015. Tres ambientes pertenecieron a la zona costera y dos a la selva baja caducifolia, utilizado un diseño latice 5x5 con cuatro repeticiones. El modelo AMMI fue útil para determinar la estabilidad y adaptación de los genotipos, ambas características fueron expresadas en las dos gráficas biplot del mismo modelo, tales gráficas explicaron 49.42% y 70.47% de la IG*A, respectivamente. Los dos genotipos con mayor rendimiento de grano fueron los híbridos trilineales CML226xHPM302 y POOL26xHPM302 con 8.153 y 8.08 t ha-1, respectivamente, con una buena estabilidad y adaptación aceptable ante la IG*A. En contra parte, el único híbrido simple HPM302 resultó estable, pero con el menor rendimiento (6.151 t ha-1). Por otro lado, las condiciones edafoclimáticas fueron determinantes para los ambientes de La Molina: LM-2015 fue el más estable de los cinco ambientes y LM-2014 resultó tener el mayor rendimiento (9.424 t ha-1) discriminando entre genotipos, con los componentes principales de la IG*A positivos.

Published: June 2019

Los problemas fitosanitarios son en gran medida la causa de pérdidas económicas a nivel mundial dentro de los cultivos agrícolas, los cuales son causados principalmente por hongos. En la República Mexicana, específicamente en el estado de Sonora, México, la superficie dirigida al cultivo de tomate, ha aumentado considerablemente en los recientes años. En los últimos ciclos de producción, se ha generado una problemática de control fitosanitario, donde los síntomas de patógenos conocidos, se confundan con aquellos de fitopatógenos ‘nuevos’ que están arribando a las áreas agrícolas, permitiendo que el técnico tenga incertidumbre de que patógeno se trata y por consiguiente no tenga éxito al aplicar un control en el cultivo. Acudiendo a servicios profesionales en laboratorios fitosanitarios, la demanda en demasía, suele ser una vía incosteable al productor. El objetivo de la investigación fue identificar los agentes causantes de enfermedades: Fusarium oxysporum f. sp. lycopersici (Raza 1), Alternaria solani y Botritys cinerea sobre los órganos muestreados para conocer el status fitosanitario actual del tomate en el estado de Sonora, a semilla, plántula, follaje y madurez fisiológica, aislándolos e identificándolos mediante la conjunción de técnicas de diagnóstico (producción de antisueros en conejos raza Nueva Zelanda, técnicas de uso de medios de cultivo, Elisa y pruebas de patogenicidad). El muestreo para la identificación de los hongos fitopatógenos se realizó de forma representativa en regiones productoras de tomate. Los resultados obtenidos muestran la identificación de tres hongos representativos y de importancia económica en el cultivo de tomate distribuido en el estado de Sonora. Se concluye que las pruebas de detección por separado no deben ser utilizadas como un método único de detección.

Michoacán es el principal estado productor de aguacate en el mundo; sin embargo, las enfermedades radiculares diezman y dañan los árboles ocasionando su muerte. El objetivo de la presente investigación fue evaluar el control orgánico del crecimiento in vitro de Phytophthora cinnamomi con aceites esenciales de orégano (Lippia berlandieri) y clavo (Syzygium aromaticum). En los meses de octubre y noviembre de 2016, se recolectaron muestras de raíces en árboles con síntomas de la enfermedad en aguacate (Persea americana Mill. var. Hass), en la huerta experimental del INIFAP ubicada en San Juan Nuevo Parangaricutiro, Michoacán. Los aislados se identificaron morfológica y molecularmente. Se evaluó el control de P. cinnamomi con aceites esenciales de orégano y clavo determinando la concentración media inhibitoria y sus límites fiduciales al 95% mediante una regresión Probit por el método de máximas verosimilitud. Los análisis se realizaron utilizando el programa estadístico R 3.4. De acuerdo con los resultados obtenidos, en relación con la inhibición del crecimiento hay una reducción en el crecimiento de P. cinnamomi. Los aceites esenciales de clavo (Syzygium aromaticum) y orégano (Lippia berlandieri) son una alternativa natural para el control del oomiceto P. cinnamomi por su actividad fungicida a bajas concentraciones y pueden incluirse en programas de manejo integrado de enfermedades.

Published: June 2019

Abstract. In this study, four different nanostructures precursors, pistachio wood, walnuts wood, forest wood and coal (Anthracite) were selected to produce activated carbon. The experiments were done in industrial scale using a rotary furnace with temperature between 850 and 920 ºC for 45 minutes followed by steam. The product was grounded and divided in three particle sizes, 8x30, 30x50, and 60x80 meshes. The physical properties and surface chemistry of the activated carbon samples were determined by imaging of BET-N2 adsorption. The results obtained from measurements of iodine and methylene blue numbers, surface area, pore volume and comparison of surface area and pore volume, show that by decreasing of particle sizes of each sample, increase the surface area and micro pore volumes significantly. The magnitude of changes in surface area with particle size is a significant factor in defining the effectiveness and suitability of an activated carbon for the production of carbon molecular sieve. Our results indicate that the highest pore volume belongs to pistachio wood, which was increased from 0.168 to 0.271 cm3/g from 8x30 to 60x80 mesh.                                        
Resumen. En este estudio, se seleccionaron cuatro precursores de nanoestructuras diferentes, madera de pistache, madera de nueces, madera de bosque y carbón (antracita) para producir carbón activado. Los experimentos se realizaron a escala industrial utilizando un horno rotatorio con una temperatura entre 850 y 920 ºC durante 45 minutos, seguido de vapor. El producto se molió y se dividió en tres tamaños de partículas, en mallas de 8x30, 30x50 y 60x80. Las propiedades físicas y la química de la superficie de las muestras de carbón activado se determinaron mediante imágenes de la adsorción de BET-N2. Los resultados obtenidos de las mediciones de los números de yodo y azul de metileno, área de superficie, volumen de poros y comparación de área de superficie y volumen de poros muestran que, al disminuir los tamaños de partícula de cada muestra, aumenta significativamente el área de superficie y los volúmenes de microporos. La magnitud de los cambios en el área de la superficie con el tamaño de partícula es un factor significativo en la definición de la efectividad y la idoneidad de un carbón activado para la producción de tamiz molecular de carbono. Nuestros resultados indican que el mayor volumen de poros pertenece a la madera de pistache, que aumentó de la malla de 0.168 a 0.271 cm3/g de 8x30 a 60x80.
Morphofunctional characteristics of leaves and fruits in Maloideae (Rosaceae): a. Microstructure of surface tissues
Authors: Kumachova T. Kh. , Voronkov A. S. , Babosha A. V. , Ryabchenko A. S.
Published: June 2019

Background. The formation of cover tissues (epidermis, cork), providing a connection with the environment, in the evolution of flowering plants was one of the main consequences of the transition to life on earth. The epidermis, which emerged as a device for protecting deeper underlying tissues from drying, subsequently acquired additional functions (participation in gas exchange and transpiration, absorption and isolation of certain substances as well as protection from the penetration of pathogens) and became a multifunctional tissue consisting of several types of cells (basic, stomatal, and trichomes). Features of the fine structure of the epidermis are of interest in representatives of the subfamily Maloideae Werber (Rosaceae Juss.), which grow, inter alia in mountain agrobiocenoses with their rather harsh conditions. They extended their area of distribution to various habitats due to the development of structural adaptations that play an important role in the formation of resistance to stressors of different etiologies.

Objective. Representatives of 4 genera were chosen as model objects from subfam. Maloideae for the study: Malus domestica Borkh., Pyrus communis L., Cydonia oblonga Mill., and Mespilus germanica L.

Materials and methods. Mature leaves and fruits were selected from the middle part of the crown of three model trees of each species. The samples were studied by scanning electron microscopy (SEM), with a freezing attachment.

Results. Leaves of Maloideae were found to be hypostomatic, while the abaxial (lower) epidermis is multifunctional: it performs a barrier function together with the cuticle. Formation of the cuticular nature can be attributed to the surface structures: peristomatic rings and ridges as well as radially extending folds, all forming a specific microrelief. The adaxial (upper) and abaxial surfaces clearly differ not only in the features of the structure, but also in the specificity of the microrelief’s arrangement. Species-specific traits were also found in the structure of the surface tissue of the pericarp. M. germanica, unlike the other species, does not have a continuous cuticular cover and wax deposits: most of a mature fruit’s surface is covered with a peeling cork layer. In the study of the surface of C. oblonga fruits, numerous rather large stomata with peristomatic rings and cuticular cushions were found similar to those in leaves.

Conclusion. Surface structures of leaves and fruits in subfam. Maloideae include formations of cuticular nature, with different specificities of microrelief shaping due to the functional load of the epidermal tissue and environmental conditions. They can also be involved in building resistance to biotic stressors. The obtained data on the features of the fine structure of surface tissues are of interest for applied and theoretical studies, especially environmental and botanical, relating to taxonomic issues.
Viability of pollen in sweet cherry (Cerasus avium) varieties of different ecogeographic origin in the Northwestern region of Russia
Authors: Orlova S. Yu. , Pavlov A. V. , Verzhuk V. G.
Published: June 2019

Background.Sweet cherry is an unconventional fruit crop for the Northwestern region of Russia. Identification of cultivars adapted to the conditions of the northwest requires a comprehensive study of cultivars of different ecogeographic origin and, specifically, morpho-physiological characteristics of pollen, which ensure the productivity of sweet cherries.

Materials and methods.The field sweet cherry collection maintained at Pushkin and Pavlovsk Laboratories of VIR served as the material for the study carried out in 2017 at the Plant Diversity Long-Term Storage Laboratory. Twenty-four sweet cherry accessions belonging to five different groups were studied: I – Northwestern (bred at VIR); II – Central; III – Central Black Soil (all three are regions in Russia); IV – Belarus; and V – Estonia. Viability of pollen was assessed by germinating on an artificial medium with 10% sucrose and 0.6% agar. Pollen viability results were statistically processed using StatSoft Statistica 13.0 and Microsoft Excel.

Results.The initial viability of pollen for almost all varieties in 2017 was low. High percentage of pollen germination was characteristic of cvs. ‘Krasnaya sladkaya’ (gr. I, 50.0%), ‘Leningradskaya rozovaya’ (gr. I, 61.8%), ‘Adelina’ (gr. III, 53.5%) and ‘Zarya Vostoka’ (gr. III, 60.3%). After storage in liquid nitrogen, the level of pollen germination increased in all cultivars of groups I and V as well as in a number of cultivars from group II (‘Raditza’, ‘Iput’, ‘Rechitsa’ and ‘Fatezh’), group III (‘Zarya Vostoka’, ‘Rondo’ and ‘Orlovskaya rozovaya’) and group IV (‘Severnaya’ and ‘Vityaz’). Pollen viability after cryopreservation significantly decreased by 8.7‑17.3% in cvs. ‘Bryanochka’ (gr. II), ‘Alebastrovaya’ (IV),’ Bryanskaya rozovaya’ (II) and ‘Adelina’ (III). Pollen viability parameters (length of pollen tubes and percentage of germinated pollen grains) positively correlated prior to immersion into liquid nitrogen from r = 0,54 (gr. III) to r = 0,76 (gr. II), while after cryopreservation, they showed weak correlation (r = 0,28) in gr. I, and strong one (r = 0,79) in group IV. In the length of pollen tubes and the level of viability, the parent cv. ‘Leningradskaya chernaya’ had practically no connection with cv. ‘Raditsa’ (r = 0.09), while with cv. ‘Meelika’ the correlation was medium negative (r = –0.49); correlations between the parent cv. ‘Krasnaya plotnaya’ and cvs. ‘Sopernitsa’, ‘Bryanochka’ and ‘Vityaz’ were medium (r = 0.57) and high (r = 0.78 and r = 0.83), respectively.

Conclusion.In their level of pollen viability, the introduced sweet cherry cultivars are similar to or even exceed the cultivars native to the northwest (bred at VIR).

Published: June 2019

The paper reports the study of peculiarities in the roughness formation of conjugate cylindrical and end surfaces of machinery at their simultaneous grind-ing with the disk periphery and the end.

The analytical dependences for the computation of altitude and step parameters of surface roughness at simultaneous grinding with disk periphery and butt are obtained the authenticity of which is confirmed in the course of experimental investigations. It is defined that altitude and step roughness parameters of cylindrical surfaces and end surfaces conjugate with them after their simultaneous grinding may differ up to 2-3 times. Lesser roughness is formed on end surfaces which is explained by the large number of disk grain tips contacting with given surfaces of a blank. The roughness step parameters of ground surfaces are influenced considerably by a rounding radius of abrasive grain tips at that the average step of unevenness along a middle line Sm is threefour times greater than the average step S on tips.

Published: June 2019

Catfish is one of the fish that has a high economical value. Catfish is accepted by society easily because of its advantages. These advantages include fast growing, good adaptive behavior, good taste, high nutrient, and cheap price. One of the factors that determine the success of aquaculture is the availability of adequate food, both quantity and quality. There are several alternative feed ingredients that can be used in the preparation of feed. One of these feed ingredients is azolla flour made from Azolla sp. plant. Azolla sp. plant contains large amount of protein up to 28,12% of its dried weight. Selection of the base material feed using Azolla sp. based on the research results Handajani (2000) which declare that the protein content Azolla sp. which is quite high, namely 28.12% dry weight. The addition of Azolla sp. in catfish feed formulation is expected to improve retention of energy and lower feed conversion ratio. The purpose of this study was to determine the addition of Azolla sp. in feed formulations affect the retention of energy and feed conversion ratio catfish. This research was conducted in July-August in the Faculty of Fisheries and Marine University Airlangga. Research method used in the study was an experimental method with complete random planning. It included five treatments and four repetitions. Treatments that were used included azolla flour inclusion 0%, 5%, 10%, 15% and 20% at the formulated feed. Data analysis that was used included statistic and descriptive. The result of the research shows that energy retention among treatments does not have significant difference. On the other hand, the feed conversion ratio also does not have significant difference. It can be concluded that Azolla sp. inclusion in the catfish feed formulation affects nothing to energy retention and feed conversion ratio.

This study aims to  analyze the  economic, technical and price efficiency of  milkfish farmers participating fish culture training at Center of Education and Fisheries Training Banyuwangi, analyzing covering factors affecting production efficiency. Analysis of data used in the form of production function analysis Cobb Douglas stochastic frontier which is estimated by Ordinary Least Square Method (OLS). Estimation of Cobb-Douglas production function model using OLS method to know the efficiency of the average performance of fish culture business. Estimates with the maximum likelihood (MLE) method to determining the level of technical efficiency, using the 4.7 frontier computing program developed by Coelli (1996). To know the efficiency of the price can be calculated by the value of marginal product (VMP) of production factor. The results show that the level of economic efficiency of milkfish culture business in Gresik East Java, based on the results of estimation using MLE method, the result of six factors of production is in rational area, but not yet efficient because the obtained coefficient value of each area of pond (X1) 0.318, fertilizer (X2) 0.079, lime (X3) 0.009, seeds (X4) 0.005, probiotics (X6) 0.066 and labor (X7) 1.311. While one feed production factor (X5) is in an irrational area because it has a coefficient value of -0.017. While the variables that influence inefficiency are experiential variables (Z1), age of farmers (Z2) and formal education (Z3) each have elasticity of -0.0711458; -0,6270106 and -0,1504381. The value of Marginal Product (NPM) of pond production area (X1) is 0.00059 (<1), Fertilizer (X2) is greater than 1 ie 3,01413, lime production factor (X3) 3,35338, the other NPM factor production such as Seed (X4) and Labor (X7), with value less than 1 (0.00075 and 0.03865), NPM Feed (X5), is smaller than one ie -0.00364 (<1 ). NPM probiotic (X6) is 95,1491 (> 1).
