Abstract

The effect of chitosan  on micropropagation of Dendrobium lasianthera J.J.Sm was observed. The media used was Vacin and Went (VW) modified with the addition of coconut water and given chitosan with several concentrations. The study was conducted at the Plant Tissue Culture Laboratory of the Department of Biology, Faculty of Mathematics and Natural Sciences, Cenderawasih University for 6 months, from April to September 2019. Experiments using a Completely Randomized Design (CRD) of 8 treatments with 3 explants in each bottle for total 3 bottle as a replication. The total explants used in this experiment was 72 explants. The concentration of chitosan were 0% , 1%, 5%, 10%, 15%, 20%, 40% and 50% separately. Observation data were analyzed using ANOVA, if there were significant differences followed by DMRT at the 5% level. Observation variables included number and length of roots, number and length of leaves. The results showed that giving chitosan 10% had a maximum effect on the number of roots and number of leaves, 6.67 and 4.67. As for the highest leaf length of 17.43 mm  and the longest root length 19.21 mm were in the media with the addition of chitosan concentration of 15%. The observations showed that chitosan  had a positive influence on the growth and development of orchids D. lasianthera plantlet  in vitro.Keywords : Chitosan, orchid, Vacin and Went, plantlet.

Abstract

The effectiveness of the learning system for elementary school students is crucial in enhancing critical thinking skills, curiosity, and basic skills, including in science education. Microscopes, as learning tools in biology and science, are essential in enhancing students’ understanding of the subject matter. The objective of this activity is to improve elementary school students’ understanding and skills in using microscopes as a tool for learning biology. The methods used included training and hands-on practice with microscopes in the Basic Biology Laboratory of the Department of Biology at the Faculty of Mathematics and Natural Sciences, Cenderawasih University, Jayapura. The participants were 35 students from Papua Harapan Elementary School. The results of the activity showed that before the training, only 15% of students were able to use microscopes properly and correctly, whereas after the training, the level of proficiency in using microscopes increased to 83%. In addition, student interest in learning biology through observation using microscopes reached 85%. This activity successfully improved students’ understanding of the parts, functions, and proper use of microscopes and provided a learning experience that was more interactive and contextual. Thus, training in the use of microscopes can be an effective strategy in supporting practical-based science learning at the elementary school level.

Abstract

The dissemination of processed white oyster mushroom (Pleurotus ostreatus) products in support of the Free Nutritious Food Program (MBG) aims to enhance the knowledge and skills of students at Qurrota A'yun Integrated Islamic Senior High School (SMA IT) Qurrota A'yun Jayapura regarding the importance of consuming nutritious food through the utilization of white oyster mushrooms as a local food ingredient supporting the MBG program. This activity was motivated by the low level of students’ nutritional awareness and the limited variety of nutritious foods available in the school environment. The methods employed included socialization, demonstrations, and hands-on training in processing oyster mushrooms into three healthy food products crispy mushrooms, mushroom nuggets, and mushroom dimsum. The activity involved 20 students from grades X and XI. Evaluation was conducted using pre-test and post-test assessments to measure improvements in participants’ knowledge. The results indicated a significant increase in students’ understanding of the benefits and nutritional value of oyster mushrooms, rising from 55% to 100%. Furthermore, 70% of the participants expressed willingness to try and consume processed oyster mushroom products as an alternative MBG food option. Crispy mushrooms emerged as the most preferred product due to their savory flavor and crispy texture. Overall, this activity successfully enhanced nutritional awareness, developed healthy food processing skills, and created opportunities for the development of oyster mushroom based products as an innovative and sustainable food source to support the MBG program in schools in Jayapura.

Abstract

Oyster mushroom cultivation is an activity that can be introduced to school students as an effective learning tool. This activity introduces children to the growth process of oyster mushrooms and increases their awareness of environmental and sustainability issues. It is also an interesting teaching and learning process that motivates students to actively participate in learning through various techniques, such as an outing class. The outing class activity focused on enriching the knowledge of SDIT Qurrota A'yun students in oyster mushroom cultivation science at the greenhouse of the biology department at FMIPA UNCEN. The activity took place from February to May of 2025. Fifty fifth-grade students attended the Outing Class. The activity aimed to educate students about oyster mushrooms, teach them how to cultivate white oyster mushrooms, and inform them about the benefits of oyster mushrooms in everyday life. Methods included focus group discussions, participatory planning, and practice. The results showed that the outing class increased students' interest and enthusiasm in learning outside the school environment. Out of 100% of the total participants, approximately 67% knew about white oyster mushrooms. Questionnaires and the activity showed an increase in knowledge about identifying and cultivating oyster mushrooms. It is hoped that this activity will motivate students to participate
