The Green movement in schools so far has produced quite a lot of plant waste, both from perennials, ornamental plants and shrubs. Waste recycling solutions have not been fully implemented, so many useful potential was wasted away. The facts in the field showed that many forage wastes of school plants thrown away or stacked in temporary landfills. That community service aimed to introduce methods of waste decomposition for vocational high school students, namely SMK N 1, SMK N 2, SMK Diponegoro, SMK YPKK 3 and SMK Karya Rini. The methods: (1). Earthworms (Lumbricus rubellus) and bioactive starter was used and hopefully would produce organic fertilizer; and (2). Demonstrations and simulations that include practice vermicomposting with bioactive starter followed by treatment on organic waste. This activity was conducted in the Laboratory of Organic Waste Treatment -Department of Biology Education, Yogyakarta State University. The results: (1). The enthusiasm of the participants in the implementation of the community service was quite high, as evident from the many curious questions about processing organic waste with vermicomposting and bioactive starter for producing the high quality of organic fertilizer; (2). Followed-up activities were expected each participant could become a pioneer of organic waste processing at their respective schools, or even in the surrounding community.The activities of students could be monitored by communication through mobile phones numbers and whatsapp accounts.
This community service aims to increase the effectiveness of learning for science SMP/MTs teachers in Yogyakarta by selecting, designing, implementing online learning media to utilize information technology and technology (ICT) in line with the development of the Industrial Revolution 4.0 due to the Covid 19 pandemic. The training is carried out in the form of workshops conducted online which were attended by science teachers at SMP/MTs in Yogyakarta from May 1 to 8, 2021. The training materials included an overview of inshot and screencast-O-Matic (SOM), the introduction of features on the Inshot and SOM applications, training make videos using inshot and SOM applications, then practical guidance. According to the pretest and posttest analysis, there was an increase in participants' knowledge regarding knowledge of using Inshot and SOM, the introduction of features in inshot, and SOM and how to apply them in the practice of making videos. This program is thought to be appropriate for the participants' needs. This is determined by a questionnaire given out after the course. 90% of attendees hoped to learn how to use the inshot programs to create short videos for online learning. Meanwhile, 10% of participants stated that they wished to learn more about the Inshot and SOM applications so they could add alternative media to their online learning. Through this training, we believe that teachers can be creative and innovative when creating online learning media; so that learning competencies can be achieved well even when they are not learning in person.
This community project seeks to strengthen Senior High School teachers' knowledge and abilities regarding the immune system, environmental cleanliness, and the practice of creating sanitizer and how to use it effectively. On Thursday, July 30, 2020, the training was conducted in the form of material explanations and face-to-face instruction in accordance with covid-19 guidelines in the PPG 1 and 2 FMIPA Rooms of Yogyakarta State University. The training materials include immunological and environmental hygiene, as well as how to make hand sanitizers according to the WHO formula. Participants' replies indicated that they expected to be able to produce hand sanitizers during the training, and the training material might assist in overcoming obstacles that may emerge in class. All participants reported that hand washing was the next training item they wished to hold, and all participants expressed an interest in using the training material while teaching. According to the test score analysis, the average post-test score of the participants was greater than the pre-test, with a 58.7% improvement. It was believed that with this training, instructors would have improved understanding and abilities regarding the immune system, environmental cleanliness, and creating hand sanitizers, which would help to prevent the spread of the virus during a pandemic.
The Black Soldiers Fly (Hermetia illucens) life cycle is unique. The uniqueness lies in the life of the larvae until the pupae and metamorphosis become relatively clean flies, do not like smelly media and tend to be in a moist to dry medium. Unlike some other types of flies, the BSF life cycle brings more advantages than disadvantages. There are various problems related to the ability of BSF larvae to decompose organic waste. An investigation was needed to determine the ability of leaf waste decomposition in the environment which is quite abundant and its potential has not been calculated. Four types of leaf waste that will be tested, namely categories A, B, C, D including A (Ketapang / Ficus Lyrata, FF), B (Markisa / Passion fruit / Passiflora edulis, FM), C (Kelengkeng / Longan / Dimocarpus longan, FK), D (Glodhogan pecut / Polyalthia longifolia, Sonn., FG). Meanwhile, E as control was an exclusive basic feed. The composition of the ratio of [medium: basic feed] BSF in each category A, B, C, and D as a medium for larval rearing, consists of: (80:20), (60:40), (50:50), (40:60) and (20:80) %. Each treatment had 4 replications. The place of maintenance is a plastic tub covered with a plastic net and the initial weight of the media composition is 500 grams. Each tub was maintained by larvae with an average weight of 20 grams/tub until they reached the pupal period. The basic feed was fermented soft bran. The parameters observed were: the bioconversion ability of BSF larvae based on the Feed Conversion Ratio (FCR). Data analysis using a completely randomized design with a nested design on 2 independent variables was carried out using SPSS version 19 software. The results showed that the type of leaf waste and the basic feed ratio had a very significant effect (P <0.01) on the ability of bioconversion based on the Feed Conversion Ratio (FCR) of BSF larvae, and the highest was in the treatment of Passion fruit waste with ratio 50: 50%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
