Abstract

Preparation of methyl salicylate use the acid catalyst by without solvents method has been done. Preparation of methyl salicylate was carried out by reacting salicylic acid with methanol and use sulfonic acid as a catalyst. The raeaction was use reflux method at 60-70 oC for 3 hours. The result of preparation of methyl salicylate were it has a yellow clear solution (like oil) and has a distinctive smell (like gandapura oil). From the result of FT-IR analysis showed the functional groups O-H phenol, C-H sp2, C-H sp3, C=O ester, C=C aromatic, C-O-C ester and C-OH phenol. Based on these results it is known that the methyl salicylate has been formed.

Abstract

The Library is one of the most important media for students. But this time the library The access often encounter obstacles in the process of borrowing books. The access constraint is to wait their turn to borrow books if the number of borrowers more than the number of operators and operators often can not find the book to be borrowed, but the book is available at the library. From the results of these interviews is known that in the process of borrowing constraints caused by the ability to book the service and the current library system, library system is closed. From the initial interview is also known that the university also has plans to improve the service system of the closed library systems (closed system) into an open library system (opened system). Activity Relationship Chart (ARC) is a working relationship map used to plan the inter-group relations in terms of relations activities is method being used in this research. ARC is an ideal technique in planning for linkages between each group of related activities.Keywords: Service Evaluation, Quality Function Deployment

Abstract

Ornamental plants are one of the resources that have the potential to be developed on a large scale due to high public interest. The dollar leaf plant is one of the most common ornamental plants. The leaves of the dollar plant are commonly used in traditional medicine. The objective of this research was to determine the antioxidant properties by means of the 2,2 diphenyl -1-picryhidrazil (DPPH) method from the methanolic extract of dollar leaf (Ficus pumila L.). Based on the results of phytochemical tests, the methanol extract is known to contain alkaloids and steroids. The dollar leaf methanolic extract showed antioxidant activity with an IC50 value of 387.753 mg/mL. From the antioxidant activity test results, dollar leaf methanol extract has relatively weak antioxidant power. Keywords: dollar leaf, antioxidant, 2,2 diphenyl -1-picryhydrazyl (DPPH) method, extract

Abstract

Salah satu masalah yang dihadapi pada saat ini dimana wabah corona virus disease 2019 (Covid-19) yang telah melanda 215 negara di dunia, memberikan tantangan tersendiri bagi lembaga pendidikan. Salah satu kebijakan yang dibuat oleh pemerintah yaitu kebijakan pembelajaran masih akan terus dilakukan dari rumah masing-masing (study from home). Masalah atau kendala baru mulai dialami orang tua, seperti kurangnya pemahaman materi oleh orang tua, tidak memiliki cukup waktu untuk mendampingi anak karena harus bekerja, kesulitan dalam mengoperasikan gadget, dan kendala jangkauan layanan internet, oleh karena itu perubahan membutuhkan waktu untuk bisa berjalan optimal. Sehingga sudah seharusnya keluarga atau orang tua memikirkan cara bagaimana anak-anaknya dapat belajar dengan baik dan lebih giat lagi di rumah. Dalam hal ini, diperlukan solusi yang lebih efektif dalam menjalankan peran keluarga untuk melaksanakan proses pembelajaran di rumah bagi anak sebagai upaya mendukung program pemerintah yaitu study from home. Dalam hal ini, upaya yang dilakukan supaya anak lebih giat belajar di rumah diantaranya yaitu menjadikan perasaan anak bahwa keluarga telah memahami keadaannya, mengerti keadaannya, bersahabat dengannya, berteman, berdiskusi apapun dibicarakan bersama sehingga anak merasa nyaman sekali berada di rumah serta perlu ditumbuhkan sikap apresiasi dari keluarga kepada anak atas capaian yang telah diperolehnya

Abstract

Tomato (Solanum lycopersicum L.) is a fruit-shaped vegetable that has the characteristics of being easily damaged. Tomato plants before, during and after harvest can be damaged quickly if the handling is not done properly, resulting in a decrease in quality. It is necessary to improve the quality and storage time of tomatoes, by using one type of coating, namely edible coating which has a function to improve the quality and storage time of tomatoes. Edible coating is a type of thin layer that is environmentally friendly and safe for consumption, which functions to maintain the quality of tomatoes from decay for a certain time. The study was conducted on edible coating research based on chitosan, pectin, starch, and carrageenan. The purpose of this article review is to compare the results of edible coatings from chitosan, pectin, starch, and carrageenan on the quality and storage time of tomatoes. The method used is the literature review method. The results showed that edible coating from cassava starch where tomatoes coated with edible coating with starch made from cassava was able to maintain the quality of tomatoes when stored until the 15th day. Chitosan showed chitosan coating with a concentration of 50 ppm was the best level for storage of tomatoes for 7 days of observation. Grapefruit peel pectin showed the best treatment was found in 3% pectin which was effective for 14 days with a weight of 0.063%. Carrageenan shows that 1.5% carrageenan edible coating stored at room temperature can extend the shelf life of tomatoes from 6 days to 10 days. Keywords: edible coating, carrageenan, chitosan, starch, pectin, tomato
