DAMPAK IMPLEMENTASI PEMBELAJARAN DARING PADA MASA PANDEMI COVID-19

At current, the Covid-19 pandemic is a global health threat with confirmed cases and high mortality. WHO declared this outbreak a global pandemic because the transmission of this virus was very fast and most countries in the world also exposed to it. Recent data updating the number of confirmed patients worldwide is 23,491,520 positive cases. Indonesia is one of the countries that has been exposed to this virus the beginning of March until now on 25 August 2020, there were 157,859 confirmed cases spread across 34 provinces and 415 districts / cities. The purpose of this study was to identify the impact the teachers, students and parents felt during the Covid 19 pandemic during the implementation of online learning. This study used a method descriptive analysis content. This method is used to describe some information about the impact of the Covid-19 pandemic on implementing online learning. The results of this study are the impact on teacher performance, that is, the loss of teacher motivation in teaching and there are teachers who do not understand use of electronic devices, the impact on the learning process is that students are not familiar with the distance learning process,Impact on parents as student guardians is issue between students and teachers and economic conditions can affect the learning process of the students. In the midst of this pandemic, parents are very influential in children's development, such as trying to create a supportive environment to motivate children in learning with these different situations, and the government is expected to participate in embracing the complaints and needs of children in learning, for example internet quotas. Hopefully with joint efforts, the pandemic will end quickly and we can return to building a pleasant situation better than before.

BUKU PENUNTUN PRAKTIKUM JARINGAN HEWAN MENGGUNAKAN VIRTUAL LABORATORY

The most problem occurs in the praticum in the real laboratory, so it's not going well. It can affect the depth of concepts, principles, laws and theories that must be understood by the biology teacher candidates. One of the alternatives that can be done is practicum to use a virtual laboratory. The purpose of research is to develop a practical guidebook for animal tissue materials in practicum activities using virtual laboratories for teacher candidates. This research was conducted at the Laboratory of PMIPA FKIP Riau University in December 2020–May 2021. It used a Research and Development (R&D) approach with ADDIE model. The instruments used are validation expert and response questionnaires. The results showed that the guide books is good quality and suitable to be used as independent learning resources to increase content knowledge for teacher candidates.

ANALISIS MUTU IKAN PATIN (Pangasius sp.) SALAI DENGAN PEMBERIAN KITOSAN DAN LAMA PENGASAPAN SEBAGAI RANCANGAN LKPD BIOLOGI SMA

The aims to determine the effect of chitosan concentration and smoking time on the quality of smoked catfish (Pangasius sp.) and produce Student Worksheet design. This research was divided into two step, there is experimental step and the Student Worksheet design. At the experimental step, used a factorial Completely Randomized Design (CRD). Factor I is the concentration of chitosan, and factor II is duration of smoking time. This study consisted of 12 treatments with 3 replications so that there were 36 experimental units. Parameters observed were protein content, fat content, water content and organoleptic on appearance, scent, taste and texture. The results showed that the effect of chitosan concentration and smoking time had an effect on treated with 3% chitosan and 3 days of smoking showed the best results, with the total protein content was 35.89%, fat content was 29.72% and water content was 15.27%. Meanwhile, the organoleptic test results of smoked catfish on the aspects of appearance, scent, taste and texture, the best treatment was also found in smoked catfish with 3% chitosan treatment and 3 days of smoking time. The results can be used as a student worksheet design on Food Additives material for class XI high school.

KARAKTER MORFOLOGIS DAN PERKEMBANGAN ANATOMIS BIJI MELINJO (Gnetum gnemon L.)

Melinjo seeds (Gnetum gnemon L.) have many benefits, that it is necessary to know its morphological and anatomical characters. This study aimed to determine differences in morphological characters and anatomical development of melinjo seeds at four seed maturity stages. The morphological observation was carried out based on the quantitative and organoleptic characteristics of the melinjo seeds: outer envelope, size, and the color of the middle envelope. Seed development was anatomically observed in slides prepared with a non-embedding method using a sliding microtome then observed through a microscope. The outer seed envelope has a green to blackish-red color in the final stage, while the seed middle envelope has a light-brown to dark-brown in the final stage. The inner seed envelope is thin, non-rigid, and attached on the outside of the endosperm. The seeds' length ranges from ±1,5 cm until ±2,25 cm at the end-stage; seeds width are 1 cm – 1,18 cm; seeds diameter are 1 cm – 1,16 cm. The anatomical development showed tissue thickening and differentiation. The middle envelope is getting thicker: 318,84 μm to 397,29 μm. Endosperm tissue cells undergo cell compaction as the seeds ripen. At the same time, embryonic tissue differentiation forms hypocotyl, epicotyl, and cotyledon.
