Abstract

The study evaluated the variety and digestibility of forages fed to sacrificial-goats in Mataram. The study was carried out by direct observation method. A total of 20 points vendors selling sacrificial goats were used as sampling locations. From all stall selling point, all types of forage as feed were collected. The collected feed samples were identified and tested for digestibility. The results showed that Turi (Sesbania glandiflora) leaves had the highest Dry Matter Digestibility (DMD), which was 65.54%, compared to the DMD of other forage samples, while the lowest DMD was obtained of Gayam (Inocarpus fagifer) leaves, which was 24.86% (P<0.05). As with the DMD value, the highest organic matter digestibility (OMD) was by Turi (61.08%) and the lowest OMD obtain by Gayam which had an OMD value of 11.85% (P<0.05). The OMD of Waru leaves (48.68%) was not different but does not show any difference of Ketapang (Terminalia catappa) leaves (44.73%). It was concluded that among the ten forages offered by vendor to sacrificial-goats; by order of their digestibility, Turi (Sesbania glandiflora), Waru, (Hibiscus tiliaceus), and Ketapang (Terminalia catappa) leaves produced the highest DMD and OMD.

Abstract

This study aims to determine the effect of different lemon marinates on Polycyclic Aromatic Hydrocarbons (PAHs) and quality of chicken satay. The percentages of lemon used 0%, 5 %, 10 % and 15 %. Chicken meat was marinated for 10 minutes in a homogeneous. The study used a Nested Completely Randomized Design. Parameters used were physical quality (pH, cooking loss and WHC), chemical quality (moisture, fat and protein content) and Polycyclic Aromatic Hydrocarbons (PAHs). Data were analyzed using Analysis of Variance (ANOVA), if the results of statistical analysis significant or very significant differences were obtained Duncan's test (UJBD) and descriptive PAH. The results of statistical analysis showed that the use of lemons marinates with different proportions had a very significant effect (P<0,01) on pH, cooking loss, WHC and moisture, fat content had a significant effect (P<0,05) but had no significant effect (P>0,05) on protein content. Chicken satay with 15% lemon marinates showed non-detectable results PAH.  The study concluded that lemon marinates can reduce the content of PAH carcinogens and affect the quality of chicken satay. The lowest levels of PAHs were found in the chicken satay that was marinated with a 15% lemon marinates.

Abstract

In the industrial revolution era, many jobs that humans could initially do turned out to be done by computers and machines. Learning in elementary schools should be carried out by integrating various disciplines, for example, through project-based STEAM learning. STEAM learning incorporates the contents of Science, Technology, Engineering, Art, and Mathematics. The STEAM project chosen for implementation is Robotis (Robot Tisu/Tissue Robot). This study aims to describe the STEAM learning design of the Robotis project and determine the effectiveness of project-based STEAM learning in improving science literacy skills. This research includes a quasi-experiment with a one-group pretest-posttest design. The study was conducted at SD A (one of the private schools in Surabaya) with an experimental class subject of 15 students and a control class subject of 13 students. The instruments used are validation sheets of teaching modules and science literacy tests. Data were analyzed using the n-gain test and the Mann Whitney U-Test. The results showed that STEAM learning design must integrate several disciplines (science, technology, engineering, art, mathematics) in one learning and be associated with real-world problems. The significance value is 0.00 < 0.05 so that it is interpreted that there is a difference between the two groups (H1 accepted) which means that STEAM learning in the experimental class provides different results between pre-test and post-test. So, it can be stated that STEAM learning is effective for improving students' science literacy skills.
