Abstract

Desa Jati, Kecamatan Masaran, Kabupaten Sragen, Provinsi Jawa Tengah merupakan sebuah desa yang terletak dipinggiran kabupaten yakni terletak di Sragen bagian barat yang berbatasan dengan Kabupaten Karanganyar. Meskipun terletak dipinggir kabupaten, namun akses dalam menuju ke kota sudah cukup mudah sehingga teknologi mampu masuk dengan mudah ke desa ini. Desa Jati sudah mulai terdampak dari adanya globalisasi ini, yakni anak-anak muda sekarang mulai kehilangan rasa kepedulian mereka terhadap nilai kebudayaan mereka salah satunya yaitu batik. Dalam mengolah atau mengelola tumbuhan di Indonesia masih belum mampu digunakan secara optimal. Masyarakat Indonesia dalam memanfaatkan tumbuhan mungkin hanya sebatas penggunaan seperti daun tumbuhan digunakan sebagai pembungkus makanan dan bunga digunakan untuk nyekar dan upacara adat saja dan hal itu belum mampu membuat nilai jual dari bagian tumbuhan tersebut menjadi optimal. Namun kini seiring perkembangan zaman bagian tumbuhan mampu digunakan untuk berbagai hal salah satunya yaitu digunakan sebagai pewarna alami dalam proses pembuatan batik dengan teknik Ecoprint. Hasil Kegiatan pengabdian kepada masyarakat yakni kegiatan Kuliah Kerja Nyata atau biasa disingkat KKN khususnya pada kelompok 192 memiliki tujuan yaitu untuk meningkatkan pengetahuan dan keterampilan kepada masyarakat tentang pemanfaatan bagian dari tumbuhan dan kain menjadi batik menggunakan teknik Ecoprint agar mampu menambah nilai jual dari tumbuhan dan kain khususnya masyarakat sejak usia dini. Pada kegiatan edukasi ini sasaran yang dituju yaitu anak-anak Sekolah dasar pada SD Negeri Jati 1 dan SD Negeri Jati 2 di Desa Jati, Kecamatan Masaran, Kabupaten Sragen, Provinsi Jawa Tengah. Kegiatan edukasi Ecoprint di kedua Sekolah Dasar ini dilakukan secara langsung kepada siswa dengan metode demonstrasi secara langsung pembuatan batik Ecoprint dengan menggunakan media totebag sebagai canvasnya oleh kelompok mahasiswa KKN. Dampak dari kegiatan edukasi ini adalah siswa memiliki pengetahuan serta keterampilan akan proses pembuatan batik dengan menggunakan teknik Ecoprint.

Abstract

  This study investigates the effects of rice straw pretreatment using sodium hydroxide and the addition of molasses as a co-substrate on biogas production through anaerobic fermentation. The pretreatment process involved immersing rice straw in sodium hydroxide solutions at three different concentrations for twenty-four hours, while molasses was added at varying levels to evaluate its effect on the fermentation process. Compositional changes in the lignocellulosic biomass were analyzed using the Chesson–Datta method, which revealed significant alterations in cellulose, hemicellulose, and lignin contents. The lowest sodium hydroxide concentration produced moderate delignification while retaining a relatively high cellulose content, indicating its potential as the optimal pretreatment condition. Molasses addition consistently increased biogas production as dosage levels rose, with the highest yield observed at the maximum molasses concentration. The combined application of the lowest sodium hydroxide concentration and the highest molasses level resulted in the maximum biogas yield, demonstrating improved substrate biodegradability and fermentation efficiency. These findings highlight the practical potential of integrating NaOH pretreatment with molasses co-substrate addition to enhance the conversion efficiency of lignocellulosic agricultural waste into renewable energy through anaerobic fermentation.

Abstract

Online distance learning during the COVID-19 outbreak presents new challenges and opportunities for teachers and students. The Blended Learning method is reported to be one of the promising alternatives. However, no specific study revealed the proper blended learning model for chemistry learning that require chemistry representation and can improve critical thinking and problem solving skills at high school level. Qualitative research using phenomenological methods was used in this study. The data collection technique used is using questionnaires, interviews, and documentation. A total of 22 respondents from master students of chemistry education, lecturers and teachers of chemistry education participated in this study. The blended learning model analyzed in this study are Rotational blended learning models (station class, Lab/Whole Group class, flipped class, and Individual), Flex, Self-Blend, and Enriched-Virtual classes. The study results indicate that the blended learning model that the respondents chose the most suitable for multiple representation-based chemistry learning was the Flipped Class model (50%), while the one that was not selected was the Individual Rotation model.

Abstract

This study aims to explore the need for virtual laboratory media (V-Lab) that integrates differentiated learning using the STEAM approach for electroplating and electropolishing. The research method used is qualitative-descriptive, with the research subjects comprising 3 teachers and 75 students from two public senior high schools and one vocational high school in Metro City, Lampung. Data collection used questionnaires, learning observations, and interviews. The results of the observations show that chemistry learning is still dominated by lectures and exercises (40%), while limited equipment, materials, and costs, as well as the risk of hazardous waste, continue to limit practical activities. Students experience significant difficulties in visualizing sub-microscopic phenomena, especially in determining ion flow (74%) and reactions at the anode-cathode (62%), resulting in a low ability to calculate Faraday's Law (60%). Cognitive data analysis shows a diversity of student abilities, with the majority being at the "need guidance" level (41%). These findings underscore the need for innovative learning media, with 100% of teachers and 77% of students agreeing with the development of V-Lab integrated with differentiated learning and the STEAM approach. V-Labs are expected to transform abstract concepts into concrete ones, increase motivation, and accelerate the learning pace of diverse students without the physical risks of a laboratory setting.

Abstract

The challenge of developing environmentally friendly synthesis methods for biologically active compounds remains a significant focus in green chemistry. This study aimed to synthesize 4'-hydroxy-4-nitro chalcone from 4-hydroxyacetophenone and 4-nitrobenzaldehyde using a grinding technique and then characterize the synthesized compounds. The 4'-hydroxy-4-nitro chalcone was synthesized via the Claisen-Schmidt grinding method for 45 minutes at room temperature. The grinding results were extracted with chloroform. The formed crystals were tested for purity by thin-layer chromatography (TLC), and further purification was carried out by recrystallization. The synthesized chalcone was characterized using FTIR, 1H-NMR, and 13C-NMR  spectroscopy. The chalcone was also tested for antibacterial activity using the disc diffusion method against Staphylococcus aureus and Escherichia coli. The results showed that 4'-hydroxy-4-nitro chalcone could be successfully synthesized from 4-hydroxyacetophenone and 4-nitrobenzaldehyde using the grinding technique, yielding orangish-white crystals with a 70.63% yield and a melting point of 173°C. Purity was confirmed by TLC, and structural characterization was achieved through FTIR, 1H-NMR and 13C-NMR spectroscopy. Antibacterial testing revealed that the synthesized chalcone produced a clear zone diameter of 9.27 mm against S. aureus and 27.88 mm against E. coli. These results indicate that the compound has relatively strong antibacterial activity against E. coli and relatively weak activity against S. aureus. This study demonstrates the effectiveness of the green synthesis method and provides valuable insights into the antibacterial properties of 4'-hydroxy-4-nitro chalcone

Abstract

Recently, research on the chemistry of natural products as medicinal has been increasingly developed; this is because natural products have many chemical components, have the potential biological activities without side effects, and are easy to obtain. One of these natural products is Lempuyang Emprit (Zingiber amaricans BL.) essential oil. The researchers guided UKM Suti Sehati to develop a new product: a hand sanitizer containing Lempuyang Emprit essential oil (LEEO). This study aims to make ten hand sanitizer formulas by varying LEEO concentrations and determine the best formula based on the physical properties and antibacterial activities. The best formulation obtained was then optimized with variations in fragrance concentration. The best product was selected by a hedonic test using 30 untrained panelists based on the parameters of color, scent, texture, pH, homogeneity, speed of drying, causing no red skin, causing no pain, and causing no dry skin. The antibacterial activity tests were performed against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 using the disk method. The LEEO isolation was carried out using steam and water distillation methods, and the chemical components of the best product was identified using the GC-MS method. Based on the hedonic test, the best hand sanitizer product contains 1.5% LEEO and 3% fragrance. This product has a strong antibacterial activity value against S. aureus ATCC 25923, with an inhibition zone of 15.95 mm, and a moderate value against E. coli ATCC 25922, with an inhibition zone of 9.42 mm. The hand sanitizer product contains 21.35% of Zerumbone and exhibits antibacterial and antioxidant capabilities.

Abstract

The primary objective of this study was to evaluate the capacity of C-4-methoxyphenyl-calix[4]resorcinarene in impeding the development of CaCO3 crust at varying concentrations of the inhibitor and different durations of contact. The research employed a seeded experimental approach using a 0.1 M CaCO3 growth solution maintained at 80 °C. The concentrations of C-4-methoxyphenyl-calix[4]resorcinarene introduced into the CaCO3 growth solution were 0, 5, 10, 20, and 40 ppm. The experimental procedure commenced with preparing crystal seeds, which is pivotal for gauging crystal growth rates. Results obtained from crystal weighing and morphological analysis through Scanning Electron Microscopy (SEM) indicated that C-4-methoxyphenyl-calix[4]resorcinarene effectively impeded the pace of CaCO3 scaling. The inhibitory efficacy of C-4-methoxyphenyl-calix[4]resorcinarene as a CaCO3 scaling inhibitor was contingent on well-regulated temperature during the heating phase. The inhibition effectiveness was positively correlated with the inhibitor's concentration; higher concentrations yielded superior suppression of CaCO3 scaling. Optimal scale reduction was observed at an inhibitor concentration of 10 ppm during a 20-minute contact period. These findings underscore the promising potential of C-4-methoxyphenyl-calix[4]resorcinarene as a viable inhibitor for mitigating scaling growth rates in various industrial fluid systems and related contexts.
