Abstract

Gardenia augusta, Merr is one of the family Rubiaceae species used as traditional medicine because it has medicinal properties, such as drug diabetes mellitus. These research have been done on this plant, among others, is the ability of the extract and the active fraction ethyl acetate extract of Gardenia augusta, Merr leaves to lowering blood sugar levels of rats. The purpose of this research was to purification of the active fraction of the ethyl acetate extract and identify the secondary metabolites of Gardenia augusta, Merr leaves as well as test that can be used antidiabetic. Purification was done by column chromatography which was eluted with n-hexane: ethyl acetate (7:1) and obtained four groups of fractions. The fractions of the TLC to obtain pure isolates F2 fraction with melting point 158-160 ° C. The antidiabetic activity of the isolate F2 fractions were tested into white rats by glucose tolerance methods. Isolate F2 fraction was identified by using UV and IR spectrophotometer. The results showed that isolate F2 fraction of ethyl acetate extract of Gardenia augusta, Merr leaves has a hypoglycemic effect of 21.05%. The secondary metabolites test showed a positive result for steroids. Analysis using UV spectrophotometer showed the electronic transition n → л * and transition л → л *. Analysis using IR spectrophotometric showed functional groups OH, C = O, CO, aliphatic C-H, C = C, C-C, CH3 symmetric and C-H outside the field. Key word: Gardenia augusta, Merr, diabetes mellitus, steroids

Abstract

Registering a trademark is very important for entrepreneurs today. Trademarks include company names and logos, names and symbols of certain products from companies and company slogans. As you know, there are still many digital startups that have not registered their trademarks. In fact, the existence of IPR certificates is considered quite important to protect its business from piracy, imitation or other problems and when there are investors who are interested in working together. Where IPR in general or trademark specifically is the foundation of a digital startup company Regulations related to brands are regulated in Law Number 20 Year 2016 Regarding Trademarks and Geographical Indications. Even though the various phenomena present show the enormous potential of the creative economy, it turns out that there are not many startups who consider IC to be an important issue, which is the problem at hand.The purpose of this thesis is; First, legal protection of trademark rights at digital startup companies that do not register trademarks in Bandung. Second, barriers faced against trademark rights in digital startup companies that do not register trademarks, Third, solutions or efforts made by the Creative Economy Agency. This type of research is sociological juridical research, which is research that emphasizes the legal aspects of the subject matter to be discussed, related to the reality in the field.From the results of research and discussion, there are three main things that can be concluded, First, legal protection of the rights to trademarks in digital startup companies that do not register trademarks can be done, based on the provisions of Article 21 paragraphs (1) letters b and c which contain the application refusal registration and be strengthened by Article 76 regarding the claim for cancellation of the mark. Second, the obstacles faced by digital startups in trademark registration are the lack of knowledge and understanding of the importance of IP protection, the lack of understanding of IP by the organizers and the Time Management related to trademark registration. Third, solutions or efforts made by Bekraf to increase awareness of digital startup companies on trademark registration by holding programs such as Facilitation of IPR registration, IPR protection seminars for ecraf products and IPR socialization etc.Keywords : Trademark, Startup Digital,Trademark Registrasion.

Abstract

This research is research into the development of a triangle area calculator application using Java which aims to collect programming group assignments. This testing was carried out using an application built with the Java programming language and the NetBeans IDE development tool, Java programming is an important skill in the field of information technology. Therefore, build a simple application to calculate the area of ​​a triangle using the Java programming language. This research is to introduce the basic concept of how to develop a triangle area calculator application using Java in the Java programming language to make it easier for students or beginners who aim to solve this problem for beginners, to teach the steps in creating Java applications, and to provide practical experience in implementing programming concepts in real project. Data was collected using techniques for creating flowcharts into Java code, testing, debugging, and evaluating results, this application meets the criteria for good software quality.

Abstract

Dalam rangka meningkatkan literasi teknologi di kalangan siswa sekolah menengah, mahasiswa Program Studi Teknik Informatika Universitas Pamulang (Unpam) melaksanakan kegiatan Pengabdian Kepada Masyarakat (PKM) di MTs Assa’adatain. Kegiatan ini berfokus pada pengenalan pemrograman menggunakan Scratch yang dipadukan dengan media Arduino. Dengan pendekatan yang interaktif dan edukatif, kegiatan ini bertujuan untuk mengembangkan keterampilan dasar pemrograman di kalangan siswa, sekaligus membuka wawasan mereka terhadap dunia teknologi. Perkembangan teknologi yang semakin pesat menuntut generasi muda untuk memiliki kemampuan literasi digital yang baik. Salah satu kompetensi yang penting adalah keterampilan pemrograman, yang menjadi dasar dari banyak inovasi di bidang teknologi. Namun, tidak semua sekolah memiliki akses atau fasilitas untuk memperkenalkan teknologi ini kepada siswanya. Melihat kebutuhan ini, mahasiswa Universitas Pamulang berinisiatif untuk memberikan pelatihan dasar pemrograman melalui media yang mudah dipahami dan menarik, yaitu Scratch dan Arduino. Scratch adalah platform pemrograman visual yang dirancang untuk pemula, terutama siswa sekolah. Dengan menggunakan Scratch, siswa dapat mempelajari logika pemrograman melalui blok-blok kode yang mudah dipahami. Ketika dikombinasikan dengan Arduino, sebuah platform perangkat keras open-source, siswa dapat langsung melihat hasil dari kode yang mereka buat dalam bentuk perangkat nyata, seperti lampu yang menyala atau motor yang bergerak. Kombinasi ini memberikan pengalaman belajar yang lebih menyenangkan dan aplikatif.

Abstract

Problems often encountered in the breeding of selincah fish are that the maturation period of the male and female parent fish sometimes does not occur simultaneously. Reproductive biotechnology can be used to store sperm (sperm cryopreservation). Cryopreservation is a storage technique using a low temperature of -196oC. Extenders and cryoprotectants play an important role in the cryopreservation process. One of the extender materials that can be used is honey. This study was conducted to determine the best dose of honey as an extender material in cryopreserving selincah fish sperm. This study used a completely randomized design with four treatments and three replications. The treatments given were (P0) 100% ringer lactate solution, (P1) 0.25% honey + 99.75% ringer lactate solution, (P2) 0.5% honey + 99.50% ringer lactate solution, and (P3) 0.75% honey + 99.25% ringer lactate solution. The results of the study showed that pre-cryopreservation of selincah fish sperm included a sperm volume of 0.5 mL, sperm pH of 7, moderate sperm consistency, sperm movement duration of 120 seconds with a percentage of motility score of 5 (100%), and sperm viability of 89.50%. The post-cryopreservation study of selincah fish sperm for 14 days of storage showed the best results at P3 (0.75% honey) with a sperm motility score of 4 (90%) and sperm viability of 79.50%. Water quality data during the maintenance of selincah fish broodstock in this study were pH 6.0-7.5 and temperature 25.5 - 28.5oC.
