Diet Digestibility and Growth Performance of Giant Gouramy Juvenile, Osphronemus Goramy Fed on Diet Supplemented Using Glutamine

Ikan gurami Osphronemus goramy sebagai komoditas unggulan ikan air tawar mempunyai pertumbuhan yang lambat. Oleh sebab itu, penelitian ini dilakukan dengan tujuan mengevaluasi penambahan glutamin dengan dosis berbeda dalam pakan terhadap kecernaan pakan dan kinerja pertumbuhan benih ikan gurami. Penelitian ini terdiri atas dua tahap yaitu uji kecernaan pakan dan uji pertumbuhan. Glutamin dengan dosis 0, 1, 2 dan 3% dicampurkan ke dalam pakan uji isoprotein dan isoenergi. Chromium oxide (Cr2O3) ditambahkan dalam pakan uji sebanyak 0,6% sebagai indikator kecernaan. Ikan uji yang digunakan adalah benih ikan gurami dengan bobot awal 2,07±0,00 g, dipelihara dalam akuarium berukuran 50x40x35 cm3 dengan padat tebar 25 ekor per akuarium. Ikan diberi pakan uji dengan frekuensi tiga kali dalam sehari yaitu pada pukul 07.00, 12.00, dan 17.00 WIB secara at satiation. Uji kecernaan pakan dilakukan selama 20 hari menggunakan metode pengumpulan feses yang dilakukan pada hari ketujuh setelah ikan diberi pakan uji. Uji pertumbuhan dilakukan selama 60 hari dan selama pemeliharaan dilakukan pergantian air sebanyak 30% dari volume media pemeliharaan pada pagi hari sebelum pemberian pakan. Hasil penelitian menunjukkan bahwa penambahan glutamin 3% meningkatkan kecernaan total (73,66±0,18%), kecernaan energi (64,79±0,22%), kecernaan protein (90,57±0,01%), aktivitas enzim protease (6,13±0,02 U g-1 protein) dan lipase (0,86±0,01 U g-1 protein) serta kadar glikogen hati (6,86±0,17mg g-1 sampel). Penambahan glutamin 2% meningkatkan efisiensi pakan (88,75±2,54%), laju pertumbuhan harian (4,25±0,07%) dan retensi protein (47,19±0,77%). Disimpulkan bahwa penambahan glutamin dosis 2-3% dalam pakan dapat meningkatkan kecernaan pakan dan kinerja pertumbuhan benih ikan gurami

Hambatan Pelaksanaan Kriteria Ketuntasan Minimal Mata Pelajaran Produktif Tata Busana SMKN 1 Lembah Gumanti

This study aims to describe the implementation of Productive KKM dressmaking courses in SMKN 1 Gumanti Valley, in terms of the criteria for determining the KKM intake (student ability), complexity (difficulty level indicator), and carrying capacity. This research is qualitative research. Subject and informant research is Professor Earning dressmaking, amounting to 5 (five) people. Data collection techniques are observation, interviews, documentation, and triangulation. Data processing techniques are data collection, data reduction, data display, and conclusion. The results of this study indicate the general implementation of the Productive subjects KKM dressmaking, where teachers are still having difficulty, namely the intake criteria (student ability), On the criteria of complexity where teachers are difficult to adjust the complexity of the material with the ability of students. As well as carrying on the criteria, lack of educational infrastructure that supports the learning process, and the number of teachers earning dressmaking that do not meet the ideal standards

Black parent involvement: An untold story

For over four decades, research has unequivocally proven academic achievement and parent involvement are directly linked. Much of the literature on parent involvement suggests it should be at the forefront of social concern if one hopes to advance towards academic excellence in America. According to researchers (Cole-Henderson, 2000; Sheridan & Gutkin, 2000) children whose parents are involved have higher education attainment rates, perform better on high stakes testing and in school achievement. However, absent from the literature are the voices of marginalized parents who bear the brunt of the blame for the achievement gap that currently exists between Black students and their White counterparts. This exploratory study examines the roles low-income Black parents construct for themselves in their children’s academic and social emotional success at home and in school. In this study, parent involvement refers to school-sanctioned, and school-authored activities in which parents participate. Ecologies of Parent Engagement (EPE) and Social Stratification were the theoretical frameworks used to situate the study. Ecology of Parent Engagement considers the how and whys of parent engagement, and how parents’ experiences with educators determine the way they engage in their children’s education in and out of the school community. Social Stratification was utilized to display how people are stratified into groups determined by their social status and social position in society. Qualitative research methods, specifically Critical Race Methodology (CRM), a counter storytelling method, and Portraiture methodology were used to provide a detailed picture of parent involvement based on the participant stories and experiences with school personnel and in their respective communities. In this study the findings unearthed race, social class, and educator perception as mitigating factors in how and why parents engaged or disconnect from their children’s school environment

Intelligent Information Loss: The Coding of Facial Identity, Head Pose, and Non-Face Information in the Macaque Face Patch System

Faces are a behaviorally important class of visual stimuli for primates. Recent work in macaque monkeys has identified six discrete face areas where most neurons have higher firing rates to images of faces compared with other objects (Tsao et al., 2006). While neurons in these areas appear to have different tuning (Freiwald and Tsao, 2010; Issa and DiCarlo, 2012), exactly what types of information and, consequently, which visual behaviors neural populations within each face area can support, is unknown. Here we use population decoding to better characterize three of these face patches (ML/MF, AL, and AM). We show that neural activity in all patches contains information that discriminates between the broad categories of face and nonface objects, individual faces, and nonface stimuli. Information is present in both high and lower firing rate regimes. However, there were significant differences between the patches, with the most anterior patch showing relatively weaker representation of nonface stimuli. Additionally, we find that pose-invariant face identity information increases as one moves to more anterior patches, while information about the orientation of the head decreases. Finally, we show that all the information we can extract from the population is present in patterns of activity across neurons, and there is relatively little information in the total activity of the population. These findings give new insight into the representations constructed by the face patch system and how they are successively transformed

Can holography reproduce the QCD Wilson line?

Recently a remarkable agreement was found between lattice simulations of long Wilson lines and behavior of the Nambu Goto string in flat space-time. However, the latter fails to fit the short distance behavior since it admits a tachyonic mode for a string shorter than a critical length. In this paper we examine the question of whether a classical holographic Wilson line can reproduce the lattice results for Wilson lines of any length. We determine the condition on the the gravitational background to admit a Coulombic potential at short distances. We analyze the system using three different renormalization schemes. We perform an explicit best fit comparison of the lattice results with the holographic models based on near extremal D3 and D4 branes, non-critical near extremal AdS6 model and the Klebanov Strassler model. We find that all the holographic models examined admit after renormalization a constant term in the potential. We argue that the curves of the lattice simulation also have such a constant term and we discuss its physical interpretation
