Abstract

Minyak atsiri merupakan minyak yang bersifat volatil, tersusun dari senyawa golongan terpenoid (monoterpen dan seskuiterpen). Salah satu tumbuhan yang berpotensi dijadikan minyak atsiri adalah tumbuhan sapu-sapu (Baeckea frutescens L.) Kepulauan Bangka Belitung. Tujuan dari penelitian ini untuk mengetahui perbandingan rendemen, karakteristik, dan komponen senyawa kimia dalam minyak atsiri daun sapu-sapu merunduk dan tidak merunduk pada umur panen di atas dan kurang dari 2 tahun. Metode yang digunakan dalam penelitian ini adalah destilasi uap air. Rendemen minyak atsiri yang dihasilkan dari tumbuhan sapu-sapu daun merunduk di atas 2 tahun (DM+2), daun tidak merunduk di atas 2 tahun (DTM+2), daun merunduk kurang dari 2 tahun (DM-2) dan daun tidak merunduk kurang dari 2 tahun (DTM-2) berturut-turut adalah 0,598%, 0,595%, 0,505% dan 0,544%. Minyak atsiri dari daun sapu-sapu merunduk di atas 2 tahun memiliki aroma dan warna lebih dominan dibandingkan dengan yang lainnya. Komponen senyawa kimia yang dihasilkan dari empat variasi minyak atsiri ini berbeda-beda. Minyak atsiri daun sapu-sapu jenis merunduk di atas 2 tahun memiliki total persentase komponen senyawa kimia area sebesar 97,49% dan merunduk kurang dari 2 tahun sebesar 97,74%. Sedangkan komponen senyawa kimia minyak atsiri daun sapu-sapu jenis tidak merunduk di atas 2 tahun sebesar 98,54% dan tidak merunduk kurang dari 2 tahun sebesar 98,38%.   Essential oil is a volatile oil, composed of terpenoid group compounds (monoterpenes and sesquiterpenes). One of the plants that has the potential to be used as an essential oil is the Bangka Belitung Islands sapu-sapu plant (Baeckea frutescens L.). The purpose of this study was to determine the comparison of yield, characteristics, and components of chemical compounds in the essential oil of sapu-sapu leaves, ducking and not ducking at harvest ages above and below 2 years. The method used in this research is the water vapor distillation method.

Abstract

Penambahan aktivator kimia dimaksudkan untuk meningkatkan luas permukaan karbon dan membuka pori-pori yang tertutup, sehingga meningkatkan kapasitas adsorpsi karbon aktif. Penelitian yang menggunakan tiga aktivator kimia yang berbeda - HCl, NaOH, dan Na?CO? - bersama dengan aktivasi fisik pada suhu 750°C menunjukkan peningkatan kualitas dibandingkan dengan proses tanpa aktivasi. Ketika memproduksi karbon aktif dari tebon jagung, hasil yang tinggi sebesar 80-82% dapat dicapai. Uji evaluasi terhadap karbon aktif menunjukkan parameter berikut: kadar air berkisar antara 6% hingga 8,79%, kadar abu antara 2,89% hingga 4,49%, dan bilangan iodin bervariasi dari 751,11 hingga 812,16. Hasil ini memenuhi standar yang ditetapkan oleh SNI 06-3730-1995. Temuan ini mengindikasikan bahwa HCl merupakan aktivator kimia yang paling efektif untuk mensintesis karbon aktif dari tongkol jagung. Kesimpulan ini didukung oleh karakterisasi FTIR dan XRD. Analisis FTIR menunjukkan adanya gugus fungsi yang khas dari arang aktif, seperti O-H, C=O, dan C-C. Selain itu, analisis XRD menunjukkan adanya SiO? amorf, yang merupakan sifat yang menguntungkan untuk adsorben yang terdefinisi dengan baik, yang diamati pada sudut 2? 20-30 derajat.   The addition of chemical activators is intended to increase the surface area of carbon and open closed pores, thereby enhancing the adsorption capacity of activated carbon. Research utilizing three different chemical activators—HCl, NaOH, and Na?CO?—along with physical activation at 750 °C demonstrated improved quality compared to processes without activation. When producing activated carbon from corn stover, a high yield of 80-82% was achieved. Evaluation tests on the activated carbon revealed the following parameters: the moisture content ranged from 6% to 8.79%, the ash content was between 2.89% and 4.49%, and the iodine number varied from 751.11 to 812.16. These results meet the standards set by SNI 06-3730-1995. The findings indicated that HCl is the most effective chemical activator for synthesizing activated carbon from corn cob. This conclusion is further supported by FTIR and XRD characterization. FTIR analysis revealed the presence of functional groups typical of activated charcoal, such as O-H, C=O, and C-C. Additionally, XRD analysis revealed the presence of amorphous SiO?, a favorable property for a well-defined adsorbent, observed at 2? angles of 20-30 degrees.

Abstract

Penelitian ini mengevaluasi efektivitas bubuk bambu yang diolah menjadi karbon aktif untuk meregenerasi minyak jelantah menggunakan tiga metode: tanpa perlakuan panas tinggi, aktivasi konvensional, dan aktivasi furnace. Aktivasi dengan KOH meningkatkan porositas dan luas permukaan. Parameter utama yang dianalisis meliputi kadar air, asam lemak bebas (FFA), dan bilangan peroksida (PV). Hasil penelitian menunjukkan bahwa arang aktif metode furnace memiliki kinerja terbaik, menghasilkan kadar air 0,05%, memenuhi SNI 7709:2019 (< 0,1 %). Sebaliknya metode konvensional dan serbuk bambu menghasilkan kadar air masing-masing sebesar 0,12% dan 0,66%. Kandungan FFA terendah sebesar 0,23 % juga terdapat pada arang aktif tungku memenuhi SNI 01-3741 2002 (<0,3%). Selain itu, bilangan peroksida yang dihasilkan arang aktif dengan metode furnace adalah 6,3 mek O2/kg, lebih baik dibandingkan metode konvensional (9,7 mek O2/kg) dan bubuk bambu (13,3 mek O2/kg), keduanya memenuhi SNI No. 01-3741-2013 (< mek 10 O2/kg). Kinerja arang aktif dengan metode furnace unggul disebabkan oleh porositasnya yang optimal, peningkatan kandungan karbon aktif, sifat hidrofobik, dan kemampuan interaksi dengan pengotor. Oleh karena itu, arang bambu yang diaktifkan dengan metode furnace menunjukkan potensi sebagai adsorben yang efektif untuk meregenerasi minyak jelantah.   This research evaluates the effectiveness of bamboo powder processed into activated carbon for regenerating used cooking oil using three methods: no high heat treatment, conventional activation, and furnace activation. The activation with KOH enhances porosity and surface area. Key parameters analyzed included water content, free fatty acids (FFA), and peroxide value (PV). The results indicated that furnace-activated charcoal performed best, yielding an oil content of 0.05%, which is compliant with SNI 7709:2019 (<0.1%). In contrast, conventional and bamboo powder methods produced water contents of 0.12% and 0.66%, respectively. The lowest FFA content of 0.23% was found in the furnace-activated charcoal, which meets the SNI 01-3741-2002 standard (<0.3%). Additionally, the peroxide value was 6.3 meq O2/kg, which is lower than the conventional method (9.7 meq O2/kg) and bamboo powder (13.3 meq O2/kg), both of which meet SNI No. 01-3741-2013 (<10 meq O2/kg). The furnace-activated charcoal's superior performance is attributed to its optimal porosity, increased active carbon content, hydrophobic properties, and interaction capabilities with impurities. Thus, furnace-activated bamboo charcoal shows promise as an effective adsorbent for regenerating used cooking oil.

Abstract

This study aims to design teaching materials that can optimize the implementation of non-routine learning strategies in the classroom. Non-routine learning focuses on the development of critical, creative, and adaptive thinking skills, so flexible, contextual devices are needed that can encourage active participation of students. The research method used is Research and Development (R&D) with an iterative design approach. The teaching materials that were designed were then validated by three experts, revised based on input, and limited trials in the classroom. The results of the study showed that non-routine-based teaching materials to support the implementation of non-routine learning strategies were very significant. The average difference in the increase in the abilities of UIN Sultan Syarif Kasim Riau students was 7.83 and UIN Ar-Raniry Banda Aceh was 7.9. Therefore, it is recommended to continue to develop and expand the use of this non-routine learning strategy in other universities to improve the quality of education in chemistry.
