Previously, commercial collagen are obtained from mammals and poultry. However, there is a huge concern about Bovine Spongiform Encephalopathy (BSE, “mad cow disease”) and avian influenza from the consumers, that is why many researcher are trying to explore the utilization of marine animals as source of collagen. The aim of this study is to gathering information about extraction collagen from Tuna (Thunnus sp.) using 1% and 3% Chloride Acid. The result indicated that the rendement was 1,42 % and 5,65 %, moisture contents 7 % and 12 %, and acidity (pH) 4,30 % and 5,19 %. These results suggested that the using 3% chloride acid in the extraction process produced higher collagen. Sebelumnya, kolagen komersial diperoleh dari mamalia dan unggas. Namun demikian, terdapat kekhawatiran yang sangat besar terhadap Bovine Spongiform Encephalopathy (BSE, “penyakit sapi gila”) dan flu burung dari konsumen, oleh karena itu banyak peneliti yang mencoba untuk mengeksplorasi pemanfaatan hewan laut sebagai sumber kolagen. Tujuan dari penelitian ini adalah untuk memperoleh informasi tentang ekstraksi kolagen dari ikan tuna (Thunnus sp.) Menggunakan Asam Klorida 1% dan 3%. Hasil penelitian menunjukkan bahwa rendemen 1,42% dan 5,65%, kadar air 7% dan 12%, serta keasaman (pH) 4,30% dan 5,19%.

Abstract
The Compton camera technique is a well-known method of visualizing the distribution of radiation sources that emit gamma rays with energies of approximately 1 MeV. One major disadvantage of this technique is that the reconstructed image is degraded owing to the appearance of artificial uneven structures caused by accumulating rings estimated from each event. In this study, we demonstrated that we can easily achieve shift-invariant gamma-ray imaging with a drastic reduction in these artificial uneven structures by rotating the Compton camera during the measurement while also applying image sharpening techniques based on the filtered back-projection algorithm used in computed tomography.

Abstract
A linewidth reduction of a distributed feedback quantum cascade laser (DFB-QCL) based on optical feedback for a mid-infrared (MIR) cavity ring down spectroscopy (CRDS) 14C spectrometer is presented. A cat-eye reflector as well as a path-length enhancement by a Herriott cell were employed for a compact optical setup. The laser linewidth was evaluated by monitoring the beat frequency between the DFB-QCL and a MIR optical frequency comb (OFC). The linewidth reduction by optical feedback was clearly observed although slow frequency drifts caused by environmental changes were still visible. A low-bandwidth beat-note lock to the OFC was conducted for long-term stabilization as well as for precise frequency scanning and thereby 14C measurement by MIR CRDS with optical feedback was demonstrated successfully.

Published: August 2020

This article aims to promote and support the physical education teacher's community in the use of playful practices with pupils with mild intellectual disabilities (MID), as a didactic medium, and a substantial educational resource of quality physical education. Firstly, it will be reviewed definitions and emergent themes on the subject shaping the theoretical framework on which this study has been built. Later, it will be presented didactic advice and guidelines for the application of playful practices, extracted from the most effective observable practices in the author's teaching experiences in specialized education institutions with pupils with MID and supported by the scientific literature. This article reinforces the notion that playful practices provide variety to meaningful learning, have great potential as a facilitator in pedagogical processes, and provide an appropriate educational response to pupils with intellectual disabilities. It also shows that teachers should reflect positive and reflective disposition to modifications and adaptations of the different elements involved in the playful practices according to educational objectives and the personal needs and interests of the children with MID. Considerations such as the instructions have to be modified to meet students’ needs, play according to children's biological age and systematic registration and monitoring in the teaching-learning process are essential. It is recommended that teachers share their experiences in pedagogical practice to learn from our differences and strengthen our coincidences, to contribute to the still insufficient bibliography in the pedagogical practices in special education.

Discomfort due to riding a motorcycle is an issue that need to be addressed as it has long-term effects of musculoskeletal disorders on motorcyclists especially among occupational motorcyclist. Thus, this study was conducted to analyse the rating of muscle discomfort and correlation with the risk factors among traffic police riders. A cross-sectional study was carried out among 137 male traffic police riders (high-powered motorcycle) with the age between 20 to 39 years old. The 100-mm visual analogue scale questionnaire included ratings of perceived discomfort scales for 20 specific body regions was used in the study. The results indicate that the lower back (left and right) were the highest mean of discomfort which were 56.6 mm and 55.9 mm respectively. This followed with right (48.5±36.2 mm) and left (48.4±30.3 mm) upper back, and right hand (47.0±33.0 mm). The mean of overall discomfort ratings for all regions were more than 20 mm. Besides, there is a strong positive significant correlation between duration of ridings (hours) and overall discomfort ratings (p<0.01, r=0.785) and moderate positive correlation between year of traffic police motorcycle riding experience and overall discomfort ratings (p<0.01, r=0.410). As a conclusion, cumulative riding hours, riding experience and no support of the back area of the body in motorcycle seat, are the most concern in this study as this are the contributing factors to the muscle discomfort among traffic police riders while riding high-powered motorcycle. Thus, this study suggested an additional feature is needed in current motorcycle design in order to enhance comforts of traffic police riders. Also, it will improve the condition of traffic police riders’ discomfort and indirectly also improve their work and health performance as well as productivity.

The effect of shared distinctiveness on source memory: An event-related potential study

Published: August 2020

AbstractAn illusory correlation (IC) is the erroneous perception that two actually uncorrelated categories are correlated. The Shared Distinctiveness Approach (SDA) explains ICs with heightened accessibility of distinctive category combinations in episodic memory. However, empirical evidence for this approach is heterogeneous. In the present event-related potential (ERP) study, we exploited the fact that more distinctive items elicit larger P300 responses than less distinctive items, which potentially predict subsequent memory performance differences for such items. Distinctiveness at encoding was created by presenting words that differed from frequently presented, positive words in valence, font color, or both. We hypothesized that shared distinctiveness (deviation in both color and valence) would lead to an enhanced P300 subsequent memory effect (SME), better source memory performance, and an overestimation of the frequency of shared distinctive items. Behavioral results indicated the presence of shared distinctiveness effects on source memory and frequency estimation. Unexpectedly, memory also was enhanced for positive items in the frequent color. This pattern also was reflected in the P300 for highly positive and negative items. However, shared distinctiveness did not modulate the P300 SME, indicating that the processing of distinctive features might only indirectly contribute to better encoding. This study shows that shared distinctiveness indeed is associated with better source memory and ICs. Because effects were observed for the most frequent and the least frequent category combination, our results imply that the processing of distinctiveness might involve attention allocation to diametrical category combinations, thereby accentuating the differences between the categories.

This study aims to determine the effect of the concentration of AB Mix nutrients on the growth and yield of pakcoy plants. This research has been carried out at the agronet house of the Faculty of Agriculture, Panji Sakti University at an altitude of 39 m above sea level (above sea level), in March-May 2019. The experimental design used a single randomized block design (RCBD), namely the concentration of the AB Mix nutrition treatment ( K). Statistical analysis showed that AB Mix nutrient concentration had a very significant effect (p <0.01) on plant height at 14 days after planting, 21 days after planting, 28 days after planting, total wet weight per plant, leaf area per plant, and economic fresh weight per plant. The nutrient concentration of AB Mix 1.2% provides the best growth and yield of pakcoy plants. The higher concentration of AB Mix nutrition given causes the total wet weight per plant to change quadratically Ŷ = -137.83x2 + 325.54x - 88.997 with the coefficient of determination (R2) = 1 so that the optimum concentration = 1.18% and wet weight is obtained maximum total planting = 103,226 grams.Keywords: hydroponics, AB Mix nutrition, pakcoy Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi nutrisi AB Mix terhadap pertumbuhan dan hasil tanaman pakcoy.
