Abstract

Abstrak. Senyawa fenolik merupakan hasil metabolit sekunder tanaman dengan banyak manfaat seperti antioksidan, antiinflamasi, antidiabetik, imunoregulasi, antikanker, antimikrobia, dan sebagainya. Kelemahan dari senyawa ini adalah kestabilannya yang rendah terutama ketika proses pengolahan dan penyimpanan. Oleh karenanya diperlukan pengetahuan tentang efek pengolahan dan penyimpanan terhadap kadar senyawa fenolik dan aktivitas antioksidan untuk mengetahui pengolahan dan penyimpanan yang tepat. Pengolahan umumnya dilakukan dengan perebusan, fermentasi, iradiasi UV C, penambahan enzim, pasteurisasi, dan pengeringan dengan oven. Dalam pengolahan dan penyimpanan, senyawa fenolik dapat mengalami peningkatan maupun penurunan bergantung suhu, lama, tingkat oksigen, paparan cahaya dan enzim yang digunakan. Hasilnya, proses pengolahan yang disarankan untuk mempertahankan senyawa fenolik adalah steam, vakum, sonikasi, blanching, pasteurisasi, freezing, fermentasi, dan perkecambahan. Untuk proses penyimpanan yang disarankan adalah penyimpanan dengan suhu dan kadar oksigen yang rendah serta terhindar dari cahaya. Stabilitas senyawa fenolik juga tidak selalu berbanding lurus dengan aktivitas antioksidannya, penurunan senyawa fenolik tidak selalu menghasilkan penurunan nilai aktivitas antioksidan. Hal tersebut karena adanya kemungkinan senyawa antioksidan lain yang ikut terdeteksi sebagai nilai aktivitas antioksidan. Kata kunci : Senyawa fenolik, pengolahan, penyimpanan, aktivitas antioksidan Abstract. Phenolic compounds are the result of plant secondary metabolites with many benefits such as antioxidants, anti-inflammatory, antidiabetic, immunoregulatory, anticancer, antimicrobial, and so on. The weakness of this compound is its low stability, especially during processing and storage. Therefore, it is necessary to know about the effects of processing and storage on the levels of phenolic compounds and antioxidant activity to determine the proper processing and storage. Processing is generally carried out by boiling, fermentation, UV C irradiation, adding enzymes, pasteurization, and oven drying. In processing and storage, phenolic compounds can increase or decrease depending on temperature, duration, oxygen levels, light exposure and the enzymes used. As a result, the recommended treatment processes for maintaining phenolic compounds are steam, vacuum, sonication, blanching, pasteurization, freezing, fermentation, and germination. The recommended storage process is storage with low temperature and oxygen levels and avoiding light. The stability of phenolic compounds is also not always directly proportional to their antioxidant activity, a decrease in phenolic compounds does not always result in a decrease the value of antioxidant activity. This is due to the possibility of other antioxidant compounds being detected as a value of antioxidant activity. Key words: Phenolic compounds, processing, storage, antioxidant activity

Abstract

Abstract. Daun yakon mengandung senyawa fenolik seperti golongan asam organik, flavonoid, dan sesqueterpen lakton yang memiliki banyak efek farmakologis. Daun yakon sebagai antioksidan mengikat secara langsung gugus reaktif radikal serta menghambat pembentukan enzim penyebab terbentuknya radikal. Sebagai antidiabetes daun yakon menurunkan kadar glukosa darah dan meningkatkan pembentukan insulin serta menghambat proses glikogenolisis dan glukoneogenolisis. Daun yakon sebagai antikanker menginduksi nekrosis sel kanker secara kemopreventif melalui tahap primer, sekunder, dan tersier. Sesqueterpen lakton merupakan senyawa antimikroba daun yakon penghambat pertumbuhan bakteri dan jamur. Asam klorogenat dalam daun yakon mengganggu aktivitas dan metabolisme mikroba dengan merusak membran sel. Sebagai antiinflamasi daun yakon meredam terjadinya inflamasi melalui penghambatan dan pengikatan faktor DNA transkripsi NF-kB dengan mengatur transkripsi mediator pro inflamasi. Secara in vitro dan in vivo daun yakon terbukti aman dikonsumsi dalam jangka panjang sampai batas dosis efektif yang diteliti. Terdapat pula hasil bahwa efek menyembuhkan setelah pengobatan selama 30 hari bersifat reversibel, sehingga daun yakon tidak dapat dikonsumsi dalam jangka waktu panjang. Perbedaan tersebut disebabkan banyak faktor seperti spesies dan jumlah hewan uji, cara pemberian dan pemilihan dosis sampel serta efek samping yang terjadi, teknik dan prosedur pengujian termasuk cara penanganan hewan selama percobaan dan keadaan sampel harus diperhatikan dalam proses pengujian. Kata kunci : daun yakon, senyawa fenolik, efek farmakologis, efek toksik Abstract. Yacon leaves contain phenolic compounds such as organic acids, flavonoids, and lactone sesqueterpenes which have many pharmacological effects. As an antioxidant, yacon leaves bind directly to radical reactive groups and inhibit the formation of enzymes that cause radical formation. As an antidiabetic, yacon leaves reduce blood glucose levels and increase insulin formation and inhibit the processes of glycogenolysis and gluconeogenolysis. As an anti-cancer agent, yacon leaves induce chemopreventive cancer cell necrosis through primary, secondary, and tertiary stages. Sesqueterpen lactone is an antimicrobial compound of yacon leaves that inhibits the growth of bacteria and fungi. The chlorogenic acid in yacon leaves disrupts microbial activity and metabolism by damaging cell membranes. As an anti-inflammatory, yacon leaves reduce inflammation through inhibition and binding of the transcription DNA factor NF-kB by regulating the transcription of pro-inflammatory mediators. In vitro and in vivo yacon leaves are proven to be safe for consumption in the long term until the effective dosage limit studied. There is also the result that the healing effect after 30 days of treatment is reversible, so that the yakon leaves cannot be consumed in the long term. This difference is due to many factors such as species and number of tested animals, method of administration and selection of sample doses and side effects that occur, testing techniques and procedures including how to handle animals during the experiment and the state of the sample must be considered in the testing process. Key words: yavon leaves, fenolic compound, pharmacological effects, toxic effects

Abstract

Investigating Students’ Conception of Acid-Base Indicators Using Three Scientific Questions-Enhanced Conceptual Change Model. Objectives:The aims of this research is to obtain the results of the analysis process and changes in students' conceptions on acid base indicators concept from the implementation of the conceptual change model enriched with three scientific questions (CCM-EWTSQ). The stages of CCM-EWTSQ are verification of misconceptions, creation of cognitive conflict conditions, providing assistance for equilibration, and reconstruction of final understanding. Methods: The research is using mixed methods which immersed quantitative research into qualitative research. The research subjects were students of the Chemistry Education Study Program, which consisted of four test students on the concept of acid-base indicators.  The data obtained were analyzed descriptively qualitatively. Findings: The results of this study are as follows. Based on the results of two misconceptions verification, students found misconceptions about the concept of acid-base indicators (4 students).  Each individual (research target) has undergone a process of changing cognition or conception in each stage of the CCM-EWTSQ on concept that students learn. The roadmap of changes in conception from stage to stage of CCM-EWTSQ experienced by each individual cannot be equated. The implementation of CCM-EWTSQ has succeeded in reducing the misconception of prospective chemistry teacher students who have verified misconceptions. Conclusion: Not all individuals who were verified had misconceptions at first and then turned into concept-aware after proceeding with CCM-EWTSQ        Keywords: misconception, CCM-EWTSQ, CCMo, accommodation. DOI: http://dx.doi.org/10.23960/jpmipa/v25i1.pp341-350

Abstract

Higher education institutions face challenges in both academic and non-academic fields due to dynamic environmental and regulatory changes. Universities must be adaptive through effective implementation of risk management (RM) to achieve organizational goals. The community service (PKM) partner in this program is the Faculty of Teacher Training and Education (FKIP) at the Islamic University of Lamongan (UNISLA), which is in the early stage of implementing RM. Based on the experience of the Internal Quality Assurance Agency (BPI) of Universitas Negeri Surabaya, a *knowledge-sharing* activity was conducted to enhance RM maturity at UNISLA. The aim of this program is to improve the partner’s ability and skills in applying RM effectively. The PKM program began in March 2025 and was carried out in four stages: preparation, material presentation, training and mentoring on risk identification, and evaluation. The activities took place from May 15 to September 26, 2025, involving 12 members of UNISLA’s quality assurance team. The results showed a significant improvement in RM understanding (p<0.001), with the average score increasing from 45.70 to 69.60. Participants were also able to complete the risk register, develop an organizational structure, and draft RM guidelines. Participants responded positively to the mentoring activities. The PKM outputs include an activity video, online media publication, intellectual property rights (IPR), a memorandum of understanding (MoU), and an article submitted to an international reputable journal. Keywords: Risk Management, Mentoring, Islamic University of Lamongan
