Batik merupakan salah satu pakaian tradisional yang menjadi ciri khas dan kebanggaan bagi bangsa Indonesia, dimana batik juga telah dikenal secara luas baik dalam skala nasional dan internasional. Peluang dalam kegiatan bisnis penjualan batik yang meningkat beberapa waktu ini dilihat oleh banyak pihak sebagai prospek yang menjanjikan. Penjualan batik secara umum di beberapa wilayah di Indonesia masih dilakukan dengan cara yang sederhana dan klasik. Untuk dapat menjangkau lebih banyak pelanggan serta memperluas area pemasaran sekaligus promosi batik, maka diperlukan media yang dapat menunjang kegiatan promosi, transaksi penjualan dan informasi batik dengan optimal. Salah satu media yang menjadi perhatian masyarakat sekarang ini adalah dengan menggunakan media website online. E-Commerce merupakan salah satu kegiatan transaksi bisnis baik barang dan jasa yang dilakukan secara elektronik dengan menggunakan jaringan internet CV Selaras Batik menyadari bahwa peranan media website dapat digunakan untuk meningkatkan omset penjualan dan juga sebagai media sarana dalam memasarkan produk batik yang mereka miliki untuk menjangkau pasar yang lebih luas lagi serta dapat meminimalkan biaya-biaya operasional seperti biaya iklan dan juga biaya sewa toko secara fisik. Penulisan paper ini bertujuan untuk menganalisa pengaruh dari penggunaan media website online dalam hal ini adalah e-commerce dengan menggunakan pendekatan B2C (Business-to- Customer) dalam upaya meningkatkan transaksi penjualan batik pada CV Selaras Batik dan juga media penyampaian informasi baik pada para pelanggan dan masyarakat umum dalam memperoleh informasi mengenai produk-produk batik yang dipasarkan oleh CV Selaras Batik.

Problem statement: Chitin, a common constituent of insect exoskeleton, could be hydrolyzed by chitinase. The research was conducted to screen chitinolytic rhizobacteria isolated from rhizosphere of chilli pepper and to determine their chitinase activity in degrading chitin of whitefly, Bemisia tabaci Genn. (Hemiptera: Aleyrodidae). Whitefly is recognized as an important pest on many crops including chilli pepper. Approach: Screening and molecular identification based on 16S rRNA sequence of chitinolytic isolates, chitinase productions, measurement of chitinase activity, characterization of chitinase and effect of the chitinase treatment on whitefly were studied. Results: A total of 25 isolates of rhizobacteria formed a clear zone on solid chitin media. Two isolates, i.e., I.5 and I.21 isolates had the highest chitinolytic index. Based on sequence of 16S rRNA gene, the isolates of I.5 and I.21 were identified as Bacillus sp. and Bacillus cereus, respectively. The highest chitinolytic index and specific activity of I.5 isolate was 0.94 and 0.11 U mg −1 proteins, respectively. Maximum production of I.5 chitinase was occured after 36 h cultivation at 30°C and pH 7.0. The highest chitinolytic index and specific activity of I.21isolate was 0.75 and 0.114 U mg −1 proteins, respectively. Maximum production of I.21 chitinase was occured after 36 h cultivation at 55°C and pH 7.0. Cell culture and crude enzyme of the isolates were tested on chitin of B. tabaci and the effect was observed using a microscope and sterile water was used as a negative control. Hydrolytic observation showed that crude enzyme of I.21 isolate could degrade chitin of B. tabaci exoskeleton and the activity was better than that of I.5 isolate. Conclusion: Chitinase produced by Bacillus cereus I.21 strain has potential application as biocontrol agents for B. tabaci.

The incidence of diapause in the polyphagous spider mite Tetranychus kanzawai was determined for 65 populations derived from deciduous and herbaceous hosts and for 33 populations from tea, at 3 temperatures under short-day conditions. Most populations on the four main islands of Japan, irrespective of the host species on which they occurred, expressed more than 90% diapause at 15°C, whereas populations on the Okinawa islands exhibited a very low incidence or no diapause. The incidence of diapause decreased when temperature was increased from 18 to 20°C in populations from warmer areas such as southern Kyushu and Honshu. This temperature-dependent decline in diapause incidence was most conspicuous in populations from Tanegashima and Yakushima Islands. The incidence of diapause at 20°C tended to be lower in populations derived from tea than those from deciduous hosts in the same, warmer areas, showing that the former have a lower capacity for diapause. The present results, together with previously published data for T. urticae, showed that the lower temperature threshold for diapause induction was higher in T. kanzawai than in T. urticae and thus the clinal decrease in diapause percentage occurred at much lower latitudes in the former at 20°C.

Within the world of gaming, there has been a move from diversions being utilized exclusively for excitement, to recreations being utilized as a medium to teach. For this matter, there are two strategies of making amusement which are gamification or game-based learning. The previous is the utilization of diversion components, such as wellbeing focuses or pioneer sheets, and they are connected to a non-gaming stage. The last mentioned, game-based learning, incorporates creating a full-fledged amusement where the means towards the conclusion, that's  to say triumph, are set in a world where the player needs to apply the lessons given to progress. Since typically an IT-related investigation, the subject chosen for this study is Blockchain, an ever-expanding division over the past decade. Diverse parts of Blockchain's makeup have been dismembered into little, comprehensible pieces of data within the applications made, which innovative understudy to the frame can take in at their claimed pace. Should this study transcend  this research, it might be beneficial for the experiments to possess two games designed and created by someone who has the  artistic and technical capabilities of making their own assets. This is able to leave a far better impression with the test subjects  and ideally receive a far better data set for examination.

Pujasera Melawai is one area in implementing the DKI Jakarta tourism office program. There are many traditional cuisine menus to choose from, one of which is Restaurant XYZ. This study determines the effect of the product, service quality, & customer satisfaction on customer loyalty in Restaurant XYZ. This study was based on quantitative methods with data collection using a questionnaire by accidental sampling and qualitative method by interviewing the owner of Restaurant XYZ. Quantitative data was taken by anyone who met the purchase requirements at least two times at Restaurant XYZ. The sample was 100 respondents that were analyzed by regression logistics. Based on the questionnaire result and interview with customers and key informants, the three indicators of product and service quality most influential to customer satisfaction and loyalty are response accuracy, product uniqueness, and employees' attention that makes customers happy and want to return restaurant. Based on the results, customer loyalty has a probability of 76.8 percent affected which product quality and customer satisfaction, service quality affects customer loyalty in Restaurant XYZ.
