Salah satu caranya adalah dengan memberikan perhatian khusus terhadap pendidikan di Indonesia. Ujian berstandar nasional merupakan kebijakan pemerintah dalam bidang pendidikan untuk menentukan standar mutu pendidikan. Matematika merupakan salah satu mata pelajaran yang nilai kelulusannya paling sedikit dibandingkan dengan mata pelajaran lainnya. Hal tersebut dibuktikan dengan menurunnya nilai UN matematika di SMK Perdana selama dua tahun terakhir. Menurunnya nilai UN salah satunya disebabkan karena kurangnya pendalaman konsep, berupa uji coba (tryout) yang diberikan oleh pihak sekolah. Padahal mata pelajaran matematika mengharuskan siswa untuk sering berlatih dalam mengerjakan soal.Aplikasi Mobile merupakan salah satu alternatif yang sangat potensial untuk dikembangkan saat ini. Dengan media aplikasi mobile ini di harapkan para siswa mampu melakukan tryout ujian nasional untuk mata pelajaran matematika kapan pun dan dimana pun. Dan aplikasi menyediakan menu pembahasan soal. Sehingga siswa dapat memperdalam serta semakin memahami soal-soal matematika. Hal tersebut akan berdampak pada kesiapan siswa dalam mengerjakan ujian nasional khususnya mata pelajaran matematika.","PeriodicalId":31937,"journal":{"name":"Jurnal Pengembangan Rekayasa dan Teknologi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47937949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Milk is a consumable ingredient that must be given to babies to support their growth and development. In general, milk is used more for ingredients of beverage products, but with culinary creativity, we can also use milk ingredients for processed food products that are non-sweetness. . One that will be tried is the making of milk crackers. Dairy products in the form of crackers have a savory and crispy taste and as food ingredients they are quite unique and interesting, so research needs to be done. This study aims to determine the physicochemical and organoleptic characteristics of milk crackers derived from liquid milk substitute and tapioca flour with liquid methodThe experimental design used was a completely randomized design (CRD) of one factor namely liquid milk substitution and tapioca flour with a liquid method with 4 treatments and 5 replications. treatment as follows: P1: Milk 25 g: Tapioca flour: 75 g, P2: Milk 30 g: tapioca flour 70 g, P3: Milk 35 g: tapioca flour: 65 g, P4: milk 40 g: tapioca flour 60 g, If there is a real effect, then a further test with an Honestly Real Difference Test is carried out with a test level of 5%.The results showed that substitution of liquid milk and tapioca flour, in the manufacture of milk crackers with liquid method had a significant effect (p <0.05) on chemical properties (water content, protein content, reducing sugar content, calcium, vitamin A), physical properties ( baking power and texture), and organoleptic (color, taste, crispness, and preference). And after further testing with a HRD test at level of 5% all treatments were significantly different.Based on the analysis results obtained the best treatment is P4 with a substituted amount of 60 gram of tapioca flour and 40 grams of liquid milk which produces a value of chemical properties namely water content 6.42%: protein content: 5.62% and calcium levels: 148.38 mg / 100g , Vitamin A 13.42 IU, the value of physical properties of baking power 83.41% and texture 1259.25g / mm and color organoleptic, taste 3.8 (flavor of milk - very taste of milk), crispness 3.82: crunchy - very crunchy, and preference 3.82.

Network Downtime can occur for many reasons, the most common is cable damage and network configuration. This condition requires a more reliable network that is not susceptible to network interference. One of the most important aspects of ensuring that network is redundancy. The method to get high is to build a backup system that will still work if it happens on the main system. Redundancy with failover can be a solution when downtime occurs on nodes in the network. Failover is a process of transferring connections to an alternative path caused by a system or hardware or network interruption or abnormality. The implementation method used is the PPDIOO method which has the stages Prepare, Plan, Design, Implement, Operate and Optimize. System implementation simulations are made using GNS3 software. This design will result in the merging of two networks from different ISP, using MikroTik routers and The Dude monitoring applications that are very useful for troubleshooting network problems in CV.
