透過相轉移催化劑合成Chromeno[4,3-b]pyrrolidine之衍生物
本研究之反應產物Chromeno[4,3-b]pyrrolidine之衍生物含有吡咯烷及二氫苯并哌喃的骨架,而此二者存在於許多藥物及天然物中,例如:尼古丁及蛋白質中的脯胺酸皆為吡咯烷的衍生物,含有二氫苯并哌喃骨架的藥物則通常被應用於消炎藥物中。本研究主要反應是以對甲基苯醌衍生物與亞胺葉立德前驅物在相轉移催化劑及無機鹼的催化下進行(3+2)環加成反應與oxa-1,6-加成反應,合成出Chromeno[4,3-b]pyrrolidine之衍生物。利用改變不同的相轉移催化劑、溶劑和無機鹼的種類及各反應物的當量數,篩選出進行本反應的最佳反應條件。在此優化條件下,進一步使用不同的掌性相轉移催化劑,以探討本反應之光學活性。並利用無機鹼的篩選,以排除背景反應發生的可能性。希望最後能於起始物上替換不同種類的取代基,以探討本反應之反應活性,並增加其未來應用的多樣性。
HOPE WASTE (House Processor Waste) with IoT (Internet of Things) as a Laundry Liquid Waste Treatment Household Environment
Washing is one of the things that must be done by every household. Rural and urban communities have to wash clothes every day, to get clean clothes so they can be reused. But it turns out that with many households doing this activity, it will cause side effects that are not good. The impact will worsen the quality of the surrounding water because this activity is not equipped with a waste treatment process, but instead is dumped directly into the nearest ditch or river. As a result, this waste causes water pollution. The chemical compositions contained in detergents are grouped into 3, namely surface active substances ranging from 20-30%, reinforcing agents are the largest detergent components ranging from 70-80% and other ingredients around 2-8%, where surfactants are the main ingredients. cleaning agent in detergent. If not managed properly, it will cause environmental problems in the future. This research was carried out for 4 months at MAN Sidoarjo and Brawijaya University. The research method used was research and development and experiment methods, and data collection techniques using the observation method. From these problems, we offer a solution by making an internet of things-based device which we call HOPE WASTE (House Processor Waste) with IoT (Internet of Things) as the processing of household laundry liquid waste. HOPE Waste is a house-shaped device that functions to treat Laundry Liquid Waste which combines electrocoagulation methods and utilizes Biosorbents, namely Barringtonia Asiatica and Activated Charcoal which are made into powder. Where the Biosorbent content can bind chemicals in laundry liquid waste so that we can combine them using environmentally friendly IoT-based electrocoagulation methods.
Introduction of Omed-Omedan Tradition Through Augmented Reality-Based Card Games To Increase The Love of Local Culture
This research is motivated by the differences in the people's perceptions, mainly youth about the omed-omedan tradition. The difference is that many people think that the omed-omedan tradition violates the norms of decency and is also called the pornography tradition. The purpose of this study is to, 1) describe the mechanism of applying omed-omedan tradition recognition attitudes through augmented reality-based card games, 2) analyz the impact resulting from the application of omed-omedan tradition recognition attitudes through augmented reality-based card games, and 3) analyze about the feasibility of application resulting from the application of omed-omedan tradition recognition attitudes through augmented reality-based card games. This research is a type of R&D research conducted at Bali Mandara State High School from July 1-September 6, 2021. The subjects of this study were the teenagers of Kaja Sesetan Indigenous Village and the object of this study was the omed-omedan tradition through augmented reality-based card games. The data collection method used is the literature studies, questionnaires, interviews, and validation questionnaires. Data is processed based on qualitative descriptive approach and quantitative descriptive approach. The results showed that the mechanism of implementing the omed-omedan tradition originated from the download of assistive devices, namely android studios and applications from AR, the impact of augmented reality-based card games was seen as very helpful in the introduction of the omed-omedan tradition and was seen as able to help increase the love of local culture, besides that the media used was also very popular by players because it was seen as interesting and very helpful. Based on the feasibility tests that have been calculated, this game is considered very feasible to implement and researchers hope that the innovations that have been created can effectively provide understanding to help out the local community about omed-omedan tradition.
