Abstract

Cancer degenerative disease is a serious problem in Indonesia, caused by free radicals, and can be prevented by antioxidant compounds. Superoxide dismutase (SOD) is the strongest enzyme that acts as a protective organism against oxidative stress. The active compound of red betel can be studied in silico as an activator of the SOD enzyme. Molecular docking visualization, physicochemistry, toxicity of red betel active compounds were studied and continued with molecular docking. The studied parameters were Gibbs free energy (ΔG) and receptor-ligand chemical bonding analysis. The test results show that the active compounds of red betel 6-Amino-2-(3-aminopropylamino)-9-(cyclohexylmethyl)- 2,3,4,5,6,7-hexahydro-1H-purin-8-one was well-absorbed dan safe for consumption with Gibbs free energy value of -9.1490 kcal/mol. Hydrogen and hydrophobic interactions of these compounds were similar to the control ligand, namely β-amyrin and Trehalose. This study concluded that the active compound of red betel 6-Amino-2-(3-aminopropylamino)-9-(cyclohexylmethyl)- 2,3,4,5,6,7-hexahydro-1H-purin-8-one has the best potential to increase the work of Cu/Zn-SOD enzymes. This compound also meets the requirements of Lipinski regulations so that it can be well absorbed orally by the body and is not carcinogenic

Abstract

The Peasant Women's Group is a forum that provides opportunities for women to advance in the agricultural sector, one of which is the Pelangi Gunung Suling, located in Barengkok Village, Leuwiliang District, Bogor Regency. This group focuses on agribusiness-processed agricultural products. But in determining the cost of goods produced by processed products, they are still based on estimates only; for this reason, it needs to be studied in determining the cost of goods produced in processed agribusinesses based on Mangosteen peel flour. This study aims to determine the cost of goods produced to determine the selling price of processed cookies produced from mangosteen peel flour. The research method is used purposively or intentionally in the Gunung Suling farmer women's group through recording during the production and documentation process and analyzed by descriptive analysis with a quantitative approach and calculation analysis using the full costing method. The results showed that the calculation of the cost of goods produced by mangosteen peel pao cakes charges raw materials of IDR 89,771 per production per day. In contrast, direct labor costs of IDR 50,000 with overhead costs only consider baking paper, fuel gas, and packaging only Rp. 21,800, -. The total production cost to produce 80 pao cakes per day is IDR 151,671, so the cost of goods produced per piece is IDR 2,020. Using the full costing method, a reasonable selling price of IDR 2,121.86 is obtained; this method can cover all production costs of making pao cakes per piece per production. Determining the cost of goods can be used as a basis for determining the selling price of the production of pao cakes made from additional mangosteen skin flour

Abstract

The library is a place that provides a vast collection of books, which are financed and operated by a city or institution, and used by people who, on average, cannot afford to buy many books at their own expense. The research was carried out in a library in a Bogor City State Elementary School, which was closed. The library visitors consisted of teachers, staff, and public elementary school students. Borrowing books is usually on the instructions of teaching teachers to do school assignments concerning books that can be borrowed in the library. Library management is still done manually in processing library data, so they often experience difficulties in managing books and membership data, collecting data on the borrowing process, and returning and making reports. In addition, library operations have not yet run optimally.The research method used is Research and Development with several stages, namely Planning and Needs Analysis, Analysis by conducting Literature Studies, interviews and observations, Design, Implementation, Testing and Integration, and Maintenance. The study results are in the form of a computerized system that facilitates library activities to run well, especially in presenting fast, precise, accurate, and safe information that can overcome various existing problems.

Abstract

Malay is spoken in the archipelago and the Malay Peninsula, becoming the official language in Indonesia, Brunei, and Malaysia. It is the national language of Singapore and the working language of Timor Leste and several other ASEAN countries. The Malay language is valuable and should be preserved so that future generations, especially in Indonesia, recognize the diversity of languages ​​that the Indonesian people have. One way to keep it is to document the Malay language in an encyclopedia, usually a thick book. Because thick books are not practical to carry everywhere and are not friendly for quick searches, the author developed a mobile application using the Android platform to make it easier for users to access information about the Malay language. The method used in this paper is A Pattern Match, a pattern search on a text string. The pattern match method is developed using System Development Life Cycle (SDLC), a common approach to application development. In this paper, the application only focuses on the Indonesian-to-Malay and Malay-to-Indonesian translation dictionary features and the poem search feature based on the keywords entered. The development of this system implements a client-server application that must connect the device to the Internet to access the server's data. The keyword search uses a pattern match, which produces output based on keywords that have similar patterns. Ten respondents utilized usability testing and showed that 85.71% thought it was good, 6.12% thought it was neutral, and 8.16% thought it was poor

The respondents were one-person farmers, seven suppliers, and one-person distributors. Data analysis is carried out descriptively and quantitatively analyzes supply realization compared to supply chain operation reference (SCOR) standards to determine supply chain performance achievements. Research shows the marketing functions carried out: sales and purchase activities, exchanges, physical functions: Packaging, transportation, facility functions: financing, standardization, risk protection, and market information. The supply chain process is the activity of the flow of goods, the flow of money, and the flow of information. Supply chain performance analysis consists of planning, procurement, delivery, and returns. The achievement analysis results in each matrix show that the realization of the supply chain has been carried out beyond the standards recommended by SCOR. The research concludes that the exchange function, the physical part, and the facility function carry out the marketing function. The supply chain process includes the activity of the flow of goods, money, and information. Supply chain performance has met the standard by 67% and the non-standard by 33% of the number of metrics recommended by SCOR. The recommendation of this study is to recruit suppliers from locations in the West Java region so that the metric component can 100% meet the standards and apply digital systems to ensure the efficiency and effectiveness of supply through blockchain technology.

Abstract

Kemang fruit is a seasonal fruit that can only be enjoyed in certain seasons and has yet to be used optimally. Processing Kemang fruit into fruit leather is one of the efforts to optimize the consumption of Kemang fruit. This study aims to determine Kemang and machete gourd fruit leather's physical, chemical, and sensory qualities. It used a completely randomized design (CRD) in which the proportion of Kemang and machete gourd puree was the factor. It consisted of three treatment levels ( 2:3, 1:1, 3:2). Data analysis used ANOVA and DMRT as the further test with a 95% confidence level. The results showed the proportion of Kemang and machete gourd puree affected physical characteristics (strong), chemical characteristics (water content and crude fiber content), and sensory quality tests (taste, color, texture). The selected fruit leather was fruit leather with a ratio of Kemang and machete gourd A1 (2:3), which has an average value of physical and chemical characteristics, namely tensile strength of 0.06 N/mm2, elongation of 9.484%, moisture content of 26.48 %, water activity (Aw) 0.78, fiber content 4.34%, and crude level (pH) 4.2. The average value of the sensory quality test, namely taste 4,940, color 7,200, aroma 5.8, texture 4.5, and the hedonic test, namely taste 6.3, color 7.0, aroma 6.5, texture 6.6, and overall 7.2. It can be concluded that the less proportion of Kemang puree compared to the machete gourd puree (2:3) will give the best characteristics of fruit leather.

Abstract

The speed of access to digital information is essential in making decisions, and Google Development requires a data access limit of no more than three seconds. This study analyzes performance, security, and other measurements among three frameworks: CodeIgniter, Laravel, and Ktupad. This research methodology uses digital forensics as a framework for the collection of functions, classes, and rules. In contrast to libraries that are only for a specific purpose, the framework comprehensively regulates how we build applications. Frameworks allow us to build applications faster because we will focus more on the subject matter as developers. SDLC (System Development Life Cycle) consists of 3 stages: Framework Testing, Framework Analysis, and Framework Evaluation. The case study of this research is an Online Exam at Junior High School 242 Jakarta, which was built using CodeIgniter Web Framework, Boostrap, JQuery, Laravel, and Ktupad Web Framework and then compares the three using the Research and Development method with the Extreme Programming (XP) approach. Comparison tool using Web Dev, Apache JMeter, and ZAP OWASP. The results of this study show that the performance values are 1-100 from CodeIgniter 77, Laravel 75, and Ktupad 99, and security values from CodeIgniter Medium, Laravel Medium, and Ktupad Low.
