    ABSTRACT The purpose of this study was to determine the effect of applying vermicompost fertilizer and POC Nasa on the growth and production of shallots (Allium ascalonicum L.). This research has been carried out in the Experimental Garden of the Faculty of Agriculture, Riau Islamic University for 4 months, starting from July to October 2018. The design used in this study was a factorial Completely Randomized Design consisting of 2 factors. The first factor is vermicompost fertilizer (K) which consists of 4 levels namely 0, 200, 400, 600 g / plot and the second factor is POC Nasa (P) consisting of 4 levels namely 0, 2, 4, 6 cc / l water. The parameters observed in this study were plant height, harvest age, number of tubers per clump, wet tuber weight per sample, dry tuber weight per sample, tuber weight loss. The last observation data were statistically analyzed and continued with a BNJ follow-up test at the 5% level. The results showed that the application of vermicompost fertilizer and poc nasa interaction significantly affected the parameters of plant height, age of harvest, the number of tubers per clump, dry tuber weight per sample, shrinkage of tuber weight, and the application of vermicompost fertilizer and poc nasa interactively had no significant effect on wet tuber weight parameters per sample with the best treatment is a concentration of 600 g / plot (K3) and 6 cc / water (P3) is a dose of 44.80 grams/plot.

    Cognitive Bias Modification (CBM) can yield clinically relevant results. Only few studies have directly manipulated memory bias, which is prominent in depression. In a new approach to CBM, we sought to simulate or oppose ruminative processes by training the retrieval of negative or positive words. Participants studied positive and negative word pairs (Swahili cues with Dutch translations). In the positive and negative conditions, each of the three study trials was followed by a cued-recall test of training-congruent translations; a no-practice condition merely studied the pairs. Recall of the translations was tested after the training and after 1 week. Both recall tests revealed evidence of training-congruent bias and bias was associated with emotional autobiographical memory. Positive retrieval practice yielded stable positive mood, in contrast to the other conditions. The results indicate that memory bias can be established through retrieval practice and that the bias transfers to mood and autobiographical memory

    Indonesia issued a policy through Presidential Regulation Number 21 Year 2016 Concerning Free Visit Visa. However, the policy turned out to be not as expected in empirical practice. Therefore this study takes the formulation of the problem of how the supervision of Foreigners before and after the enactment of Presidential Regulation Number 21 Year 2016 Concerning Free Visit Visa tentang Bebas Visa Kunjungan at the Regional Office of the Ministry of Law and Human Rights of the Special Region of Yogyakarta and how to optimize the supervision of Foreigners at the Regional Office of the Ministry of Law and Rights Human Rights Special Region of Yogyakarta in the future. As a normative legal research, secondary data collection is done by studying documents or library materials. The results of data collection through the study of documents or literature are then combined by examining, analyzing, and understanding relevant information which is then taken to be limited to relevant matters and in accordance with the topic being raised. In addition, this study uses several approaches as a guiding direction so that it can facilitate data collection, namely the statute approach and conceptual approach. Based upon the research questions above, it could be proposed some primary conclusions, i.e.: in carrying out the supervision of the absence of standard operating procedure on the Alien supervision team and the limited number of human resources especially PPNS Immigration. In addition, the amount of the supervision budget is not proportional to the increasing number of foreigners who enter after the enactment of Presidential Regulation Number 21 Year 2016 Concerning Free Visit Visa

    Watas Hutan Lake is one of the oxbow lakes in the Kampar Regency. In the areas around the lake, there are activities such as oil palm, rubber and banana plantations. To understand the water quality in general, a research was conducted from April to May 2015. This research aims to determine the water quality of the lake based on physical and chemical characteristics and makrozoobenthos community structure. There were three stations, 3 sampling points/ station. Water samples were taken 3 times, once/ week. Parameters measured were abundance, uniformity and dominancy index of the macrozoobenthos and several water quality parameters such as temperature, turbidity, depth, total suspended solid, pH, dissolved oxygen, BOD5, nitrate, phosphate, substrate type, and organic materials. Results shown that there were 12 species (4 classes) of macrozoobenthos, with abundance 353 organisms /m2. There were Oligochaeta (4 species), Insects (3 species), Gastropods (3 species), and Bivalves (2 species). In general, the H' was 2.62-2.82; C was 0.17-0.19 and E was 0.79-0.85. Water quality parameters are as follows : temperature 29-300C, turbidity 4.00-6.30 NTU, depths 1.29-4.03 cm, TSS 4.00-5.30 mg/L, pH 5, dissolved oxygen 2.00-2.73 mg/L, BOD5 5.20-5.50 mg/L, nitrate 0.04-0.06 mg/L and phosphate 0.75-1.14 mg/L. The value of WQI-NSF index of the Watas Hutan Lake was 22.21-24.83, indicates that this river is badly polluted. There was muddy substrate with 39.03-42.20% organic materials content in each area. Based on the values of H', C and E in the macrozoobenthos community, it can be concluded that the aquatic ecosystem in the Watas Hutan Lake is balance

    DEMO: Using TwitterTrails.com to Investigate Rumor Propagation

    Get PDF
    Social media have become part of modern news reporting, used by journalists to spread information and find sources, or as a news source by individuals. The quest for prominence and recognition on social media sites like Twitter can sometimes eclipse accuracy and lead to the spread of false information. As a way to study and react to this trend, we demo TWITTERTRAILS, an interactive, webbased tool (twittertrails.com) that allows users to investigate the origin and propagation characteristics of a rumor and its refutation, if any, on Twitter. Visualizations of burst activity, propagation timeline, retweet and co-retweeted networks help its users trace the spread of a story. Within minutes TWITTERTRAILS will collect relevant tweets and automatically answer several important questions regarding a rumor: its originator, burst characteristics, propagators and main actors according to the audience. In addition, it will compute and report the rumor’s level of visibility and, as an example of the power of crowdsourcing, the audience’s skepticism towards it which correlates with the rumor’s credibility. We envision TWITTERTRAILS as valuable tool for individual use, and especially for amateur and professional journalists investigating recent and breaking stories

    Hydrolysis of goat milk protein by bromelain generates fractions 10 kDa which act as antimicrobe. The fractions contain some peptides that not all were biologically active. Sequence analysis and modeling of the peptides sequences are important to predict their potential bioactivities. The aims of this study were to obtain physicochemical and structure prediction of peptides and their relation with antimicrobial activity. The study was conducted by sequencing of selected fraction in the electrophoresis gel, analyzing and modeling. Analysis of the peptide showed that peptide VLVLDTDYK that predicted from β-lactoglobulin sequence had similar sequence with antimicrobial peptide indolicidin which active to Gram positive bacteria. Peptide LVNELTEFAK was potent to be antimicrobial peptide with therapeutic index 28.69. Modeling of the peptide showed that peptide LVNELTEFAK was able to form helix which important for interaction with microbial membrane. Replacing 2nd amino acid Valine (V) to Alanine (A) and 4th amino acid Glutamic acid (E) to Serine (S) might able to increase the therapeutic index to 94.91. Based on the result, peptide LVNELTEFAK potent to be antimicrobial peptide and replacing certain amino acid was able to increase therapeutic index and its antimicrobial activity
