Jengok River has a high value for the Kutaliman community. The community utilizes the ecosystem services of the Jengok River and is inseparable from the presence of riparian vegetation, which controls water quality. This study aimed to determine riparian vegetation structure on the Jengok River, Kutaliman, Kedungbanteng district, and Banyumas Regency. The research was conducted in October-November 2022 in the Jengok riparian zone using a quadrat transect with sizes 20x20 m2 for trees dan 2x2 m2 for understoreys. Data were analyzed using the Shannon-Wiener Diversity Index (H'), the Modified Hill's Ratio Evenness Index (e'), the Margalef Richness Index (DMg), and the Important Value Index (IVI). The results show that the diversity of riparian vegetation based on the Shannon-Wiener Diversity Index (H') is a moderate category, and the Evenness Index (e') is the distribution of individuals per species evenly. Furthermore, the Margalef Richness Index (DMg) shows 4.51 for trees and 4.34 for understorey. The highest IVI in the tree stratum was Lansium domesticum Corrêa. In contrast, in the understorey stratum was Musa paradisiacal L. This indicates both species have an essential role in their community

The purpose of the research in this article is to develop a student self-assessment instrument in learning biology. In addition, to determine the correlation of the results of the assessment conducted by the teacher and self-assessment by students. The method used is Research and Development (R & D) with a trial class, namely XI MIPA 2 SMA N 103 Jakarta. The Self-Assessment Instrument for Measuring Student Attitudes and Activities consists of (A) Cover, (B) Introduction Page, Table of Contents, and Guide Information, (C) Introduction, (D) Questions and Answer Sheets, (E) Score Calculations, (F) Closing and Bibliography. The questions consist of 19 questions using a rating scale with indicators: Spiritual Attitude, Honesty, Discipline, Responsibility, Tolerance, Environmental Care, Curiosity Attitude, Critical Thinking Attitude, Perseverance, Thoroughness, Cooperation, Creativity, Observing, Interpreting and Associating, Asking a question, Formulating tentative hypotheses or conjectures, Using tools and materials/performing scientific activities, Applying concepts, and Communicating. Based on the Spearman Rank Correlation Test, there is no match (correlation) between raters X (students) and raters Y (teachers). However, students stated that it was effective as a form of self-reflection.

Porridge is one of the processed foods made from rice, which varies relatively from one region to another. The Batak Phakpak ethnic group in North Sumatra has wisdom in making traditional porridge known as ginaru. This research aims to explain the ethnobotanical study of ginaru as a traditional porridge. The research method was carried out using an ethnobotanical approach using interviews and observations. Data analysis was carried out qualitatively by explaining the role of plants in making ginaru. Ginaru is a traditional Batak Phakpak porridge that can be made with the main ingredients of groats (a by-product of the rice milling process) or rice and cassava (Manihot esculenta). The pulp is brownish yellow in color, has a distinctive aroma, and is rich in nutrients. A total of 15 species from 11 families and 13 genera of plants are used to make ginaru. As many as 40% of the plants used as spices in making ginaru are rich in essential oils and have anti-microbial activity. Andaliman (Zanthoxylum acanthopodium) and galugur acid (Garcinia atroviridis) are typical Sumatrean spices that have great potential to be developed as natural food preservatives.

Pendekatan pengetahuan lokal pada produk terfermentasi (etnomikrobiologi) bertujuan menggabungkan kaijan produk lokal terfermentasi dengan hasil refleksi pengetahuan lokal. Etnomikrobiologi dapat menunjang keterampilan para siswa untuk mengolah produk lokal yang melibatkan aktivitas, salah satunya tempe koro benguk (Mucuna pruriens) yang memiliki nilai nutrisi tidak kalah dari tempe pada umumnya. Oleh karena itu, urgensi edukasi dan sosialisasi proses pembuatan perlu dilaksanakan untuk menunjang pengetahuan produk-produk bagi para siswa, serta dapat meningkatkan keterampilan mereka setelah memahami teori produk lokal terfermentasi. Tujuan kegiatan pengabdian ini yaitu mentransfer pengetahuan melalui sosialisasi teori dan praktik pembuatan tempe koro benguk kepada para siswa dan Guru di SMA Yadika 8 Jatimulya. Pelatihan ini dilaksanakan di SMA Yadika 8 Jatimulya, Kota Bekasi, Jawa Barat. Kegiatan terlaksana pada bulan Juli 2024. Pelaksanaan pengabdian kepada masyarakat (PKM) dilaksanakan dengan dua bagian utama. Bagian pertama yaitu sosialisasi dalam bentuk pemaparan materi kegiatan PKM. Bagian kedua yaitu pelatihan langsung pembuatan tempe berbahan dasar kacang koro benguk. Kegiatan PKM yang dilaksanakan di SMA Yadika 8 Jatimulya pada para siswa dapat memberikan pengetahuan dan pemahaman tentang integrasi kearifan lokal kacang koro benguk dan pemanfaatannya sebagai produk pangan tempe koro benguk. Hasil evaluasinya 64% siswa menyatakan kegiatan PKM sangat bermanfaat, sebanyak 70% siswa tertarik untuk membuat tempe koro benguk dan sebanyak 76% siswa berpendapat bahwa kegiatan PKM pembuatan tempe koro benguk sesuai dengan kebutuhan siswa dalam menunjang pembelajaran materi bioteknologi disekolah. Praktik pembuatan tempe koro benguk menjadi bagian penting pada pengembangan pengetahuan dan keterampilan siswa yang terintegrasi langsung dengan kearifan lokal serta memberikan pemahaman siswa pentingnya menjaga lingkungan untuk keberlangsungan hidup keanekaragaman hayati sebagai penunjang pembelajaran siswa

Crinum asiaticum is a type of Amarallydaceae has been long used as a traditional medicine. The purpose of this article is to explain the relationship between the use of C. asiaticum as a traditional medicine and its bioactivity. The method used in writing the article is a literature review on some research published online using the keyword C. asiaticum, uses of C. asiaticum and bioactivities of C. asiaticum. The results obtained were then synthesized to explain the utilization and bioactivity of C. asiaticum. The traditional medicine of C. asiaticum is used to treat fever, treat fractures, sprains, inflammation and treat back pain. C. asiaticum has bioactivity as an antioxidant, antidiabetic mellitus, antimicrobial, anti-cancer, anti-inflammatory, analgesic and anti-urolytic. Licorin, crinamin and 6-hydroxycrinamine are compounds that are responsible for anti-cancer, so it is potential to be developed as an alternative anti-cancer because they are easily found in the environment.

This study aims to explain the use (biofuel) and toxicity of J. curcas. This study is based on an online literature study on Google Scholar using the keywords J. Curcas and toxicity of J. curcas. Inedible vegetable oil (biodiesel), such as castor oil, is considered a future raw material because it is a non-edible oil and does not cause food versus fuel conflicts. The potential of J. curcas as a biofuel is related to the oil content consisting of saturated fatty acids, palmitic acid, stearic acid and unsaturated fatty acids, oleic acid, and linoleic acid. Poisoning due to side effects of J. curcas seeds occurs in humans, especially children and also in the environment. Symptoms of poisoning caused by J. curcas can be analyzed through clinical signs, and the effects vary greatly, depending on the concentration, frequency, part eaten and the processing process. Accidentally ingested J. curcas seeds cause clinical syndromes such as restlessness, severe vomiting, and dehydration. Curcacycline A and curcin compound have been successfully identified from J. curcas with antitumor activity. The potential of J. curcas as an antitumor needs to be studied further to find alternative treatments for cancer and tumours.

The study revealed as many as 6 species from 3 families used in the preparation of betimun herb, Zingiberaceae was the family with the highest number of species (4 species). The used part of all plant species was leaves, while the acquisition source was from homegarden. The betimun herb was made by boiling the plants leaves. The usage way by confining the user with a sarong then the herb placed between his/her legs. Biological activities contained in the secondary metabolite compound composition of betimun herb were anti-fungal, anti-bacterial, antioxidant, aromatherapy, anti-oxidant, anti-glycation, sedative, anti-hypertensive, and astringent. This study proved that the betimun concoction has roles in eliminating body odor, fatigue, and aches; preventing and treating vaginal discharge; recovering the postpartum women's condition; slowing down the aging process, and accelerating the metabolic process. Betimun concoction potentially to be developed as a ready-use product such as phyto-simplicia.
