Every household produces waste cooking oil that was discharged into the environment without any environmental control. This situation is exacerbated by the lack of public knowledge about the impact of it on health and the environment. Because of that, that was necessary to have an innovation in the use it into products of economic value as solid soap products. This activity was carried out with the PKK Karang Anyar partner, Sawah Besar, Central Jakarta which was conducted by online due to the Covid-19 Pandemic period. This activity was able to encourage the independence economic of partner eco-based. The partners agreed that the training provided could increase the added value of waste cooking oil waste, prevent environmental damage, and increase community entrepreneurship. In addition, it could reduce household expenditure in terms of reducing spending on washing agent related to the economy that was felt heavy when Pandemic Covid-19.

This study aims to analyze the achievement of each indicator that measures students' mathematical understanding abilities in basic physics courses on particle dynamics material. This research is a qualitative descriptive study that seeks to describe the analysis of students' mathematical understanding abilities. The research subjects were 6 class 3 semester students of biology education consisting of 198 students. The data collection method used includes tests of students' mathematical understanding abilities in basic physics courses which include particle dynamics material. Based on the results of the study, it was concluded that the level of ability of biology education students in basic physics courses was as follows: (1) Students already had the ability to solve problems was good enough on particle dynamics material from questions 1 to 5 had an average percentage of 56.2% , (2) Students have reasoning abilities (reasoning on particle dynamics material from questions 1 to 5 have an average percentage of 14.4%, (3) Students have communication skills (communication) on particle dynamics material from questions 1 to 5 have The average percentage is 12.2%, (4) students have the ability to make connections to the dynamic material of particles from questions 1 to 5, have an average percentage of 12.4%; (5) students have representation ability ) on the particle dynamics material from questions 1 to 5 has an average percentage of 4.8%.

Shifts in lifestyle and food consumption patterns of the community have an influence on the nutritional status of the community. Along with the development of science and technology, people are faced with an unhealthy lifestyle, people tend to prefer and like the types of practical and fast food, soft drinks that are widely circulated in the market or contemporary drinks that are trending in society, lack of exercise, unbalanced diet, and much more. Based on the results of observations made, it shows that in the Jl. Budi Mulia RT 04 RW 07, Pademangan, North Jakarta that teenagers in this area consume high levels of fast food. One way for optimal health is to regulate the food consumed by paying attention to good nutritional intake. then our community service team will provide training on making "Nugget Processed Creations from Banana Hearts as an Alternative for Healthy Snacks" and obtained data that: 1. As many as 17 people or 85% answered that they had never made nuggets from banana hearts before, 2. as many as 19 people or 95% answered that they would make nuggets from banana hearts after receiving training, 3. as many as 15 people or 75% answered that they would make nuggets from banana hearts after receiving training as a business opportunity.

Analisis Pembelajaran DaringWabah penyakit pandemi akibat COVID-19 telah berdampak pada dunia pendidikan tinggi di Indonesia, salah satunya adalah pembelajaran mata kuliah filsafat MIPA bagi mahasiswa Program Studi Pendidikan Biologi Universitas Indraprasta, PGRI. Namun, mahasiswa harus melaksanakan perkuliahan berbasis daring untuk menekan rantai penyebaran COVID -19. Tujuan penelitian ini adalah untuk memperoleh gambaran umum dan menganalisis pembelajaran mata kuliah filsafat MIPA berbasis daring pada masa pandemi. Metode penelitian yang digunakan adalah metode deskriptif kualitatif dengan pengumpulan data dilakukan melalui survei dengan menyebarkan kuesioner melalui link yang disebarkan melalui grup WhatsApp sebanyak 198 mahasiswa pada semester III Prodi Pendidikan Biologi. Berdasarkan hasil kuesioner melalui WhatsApp, 38% responden menyatakan memahami materi yang disajikan secara daring. Persepsi mahasiswa terkait penyelenggaraan mata kuliah MIPA berbasis daring terkadang menyenangkan, sebesar 74,7% atau 148 tanggapan. Aplikasi mata kuliah Filsafat MIPA berbasis daring yang paling disukai mahasiswa adalah WhatsApp group (49,5%), sebesar 98 responden. Mengenai mata kuliah Filsafat berbasis daring Program MIPA, 103 mahasiswa-responden (52.1%) berpendapat bahwa lebih menyenangkan daripada kuliah langsung tatap muka. Pada aspek pemahaman mahasiswa dalam pembelajaran daring mata kuliah filsafat MIPA berbasis MIPA di Prodi Pendidikan Biologi, 103 siswa (52%) merasa mampu memahaminya. Kendala yang paling sering terjadi selama pelaksanaan pembelajaran mata kuliah filsafat MIPA berbasis daring adalah kuota internet yang mana membutuhkan cepat boros dengan 73 respon siswa atau 36,9%.
