  • Ekstraksi Minyak Atsiri dari Bunga Mawar (Rosa hybrda L.) dengan Metode
           Solvent Free Microwave Extraction

    • Authors: Yuyun Yuniati, Saras Nurani Putri, Pradipta Risang Ratna Sambawa, Donny Satria Bhuana, Mahfud Mahfud

      Abstract: To date, essential oils still play an important role in various aspects of human life. Flowers are essential oil-producing plants that still need to be further explored, of which rose petals (Rosa hybrda L.) are an option for types of flowers that have the potential to produce economical essential oils. In this study, solvent-free microwave extraction (SFME) was used as an essential oil extraction method, which is considered safe because it does not use heat energy and chemical solvents which can be considered to trigger a decrease in the quality of the oil extract. The optimum microwave power in this study is 560 Watt with a yield of 0.0124%. The difference in the value of the feed intake ratio to the volume of the distiller (F/D) influences yield, where the F/D value of 0.15 g/mL gives the highest yield value of 0.0145%. The result of the Gas Chromatography Mass Spectrometry (GCMS) analysis shows rose flower essential oil extract provided a profile of 12 compounds, of which three dominant compounds are β-phenylethyl acetate, 2-isopropyl-5-methyl-9-methylene-bicyclo-1-decene, and nonadecane. Keywords: Extraction, rose flower petals, solvent-free microwave extraction (SFME), essential oils Hingga saat ini, minyak atsiri masih memegang peranan penting untuk berbagai aspek kehidupan manusia. Bunga-bungaan merupakan tanaman penghasil minyak atsiri yang masih perlu dieksplorasi lebih lanjut, yang mana mahkota bunga mawar (Rosa hybrda L.) adalah satu opsi jenis bunga yang berpotensi sebagai penghasil minyak atsiri bernilai ekonomis. Pada penelitian ini digunakan solvent-free microwave extraction (SFME) sebagai metode ekstraksi minyak atsiri yang dinilai aman karena tidak menggunakan energi panas dan bahan pelarut kimia yang dapat dianggap memicu penurunan kualitas ekstrak minyak. Daya microwave optimum pada penelitian ini adalah 560 Watt dengan perolehan yield sebesar 0,0124%. Perbedaan nilai rasio feed masuk terhadap volume distiler (F/D) memberikan pengaruh terhadap hasil rendemen, yang mana nilai F/D 0,15 g/mL memberikan nilai rendemen tertinggi sebesar 0,0145%. Hasil analisis Gas Chromatography Mass Spectrometry (GCMS) menunjukkan bahwa ekstrak minyak atsiri bunga mawar memberikan profil 12 senyawa dengan tiga senyawa dominan yaitu β-phenylethyl acetate, 2-isopropyl-5-methyl-9-methylene-bicyclo-1-decene, dan nonadecane. Kata kunci: Ekstraksi, mahkota bunga mawar, solvent-free microwave extraction

  • Effect of Stirring Time on Sodium Silicate Synthesis From Mount Kelud
           Volcanic Ash

    • Authors: Isna Nurhidayati, Endang Tri Wahyuni, Nurul Hidayat Aprilita, Sarwendah Ratnawati Hermanto
      Pages: 48 - 53
      Abstract: This study performed the synthesis of sodium silicate from the volcanic ash of Mount Kelud with various stirring time in the sodium silicate synthesis process. Synthesis of sodium silicate was carried out using alkaline extraction at low temperature. This method is based on the solubility of silica under alkaline conditions and is proven to be more effective than the smelting method. The dissolution of silica contained in the volcanic ash of Mount Kelud was carried out using NaOH solution to form a Na2SiO3 solution. This process also studied the effect of stirring time on the amount of dissolved silica, with the stirring time of 0.5; 1; 1.5; 2; 2.5; 3 and 4 hours. The dissolved silica levels were tested using AAS. The amount of dissolved silica increased sharply with the longer length of stirring time, however for a stirring time of more than 2.5 hours, the dissolution was slow. The study revealed that the optimal result time was obtained from the stirring time of 2.5 hours with dissolved silica content of 19.82%. Keywords: volcanic ash, silica, sodium silicate, stirring time

  • Analisis Sidik Jari Kromatografi Lapis Tipis Tanaman Anting-Anting
           (Acalypha indica L.)

    • Authors: Muhammad Teguh Laksono, Elok Kamilah Hayati
      Pages: 54 - 62
      Abstract: Anting-anting plant (Acalypha indica L.) is a plant that the community has used as raw material for herbal medicine. Anting-anting plants contain chemical compounds, so it is difficult to ensure these plants' safety and quality control. The research objective was to validate the method by knowing the stability, specificity, precision, and rigidity of the chromatographic profile of alkaloid compounds in the TLC analysis of the anting-anting extract. Extraction was carried out using ethyl acetate solvent for 20 minutes with a frequency of 42 kHz. The eluent used is cyclohexane: toluene: diethylamine (75:15:10) with Dragendorff reagent. The method of validation was acceptable according to the criteria except for the stability test of the analyte during chromatography. The instability of the analyte is indicated that not all spots form a straight diagonal line. The specificity of the method was carried out by comparing the fingerprint patterns of the leaves of the anting-anting with ekor kucing (Acalypha hibsida Farm.) and teh-tehan plants (Acalypha siamensis). The fingerprint profile showed a yellow stain (Rf = 0.39) on the leaves of the anting-anting, which did not appear in the fingerprint profiles of the two comparison samples. Keywords: anting-anting, fingerprint analysis, thin layer chromatography, method validation Anting-anting (Acalypha indica L.) merupakan tanaman yang telah dimanfaatkan masyarakat sebagai bahan baku obat herbal. Anting-anting mengandung banyak senyawa kimia sehingga sulit menjamin keamanan dan pengendalian mutu dari tanaman tersebut. Penelitian ini dilakukan untuk validasi metode dengan mengetahui kestabilan, spesifitas, presisi, dan ketegaran profil kromatografi senyawa alkaloid pada analisis KLT ekstrak anting-anting. Ekstraksi dilakukan menggunakan pelarut etil asetat selama 20 menit dengan frekuensi 42 kHz. Eluen yang digunakan adalah sikloheksana : toluena : dietilamin (75:15:10) dengan reagen Dragendorff. Validasi metode dapat diterima sesuai kriteria kecuali uji stabilitas analit selama kromatografi. Ketidakstabilan analit ditunjukkan dengan seluruh noda yang dihasilkan tidak membentuk garis diagonal yang lurus. Spesifitas pada metode dilakukan dengan membandingkan pola sidik jari daun anting-anting dengan daun ekor kucing (Acalypha hibsida Farm) dan daun teh-tehan (Acalypha siamensis). Profil sidik jari menunjukkan bahwa terdapat noda berwarna kuning kehijauan (Rf = 0,39) pada daun anting-anting yang tidak muncul pada profil sidik jari kedua sampel pembanding tersebut. Kata kunci: anting-anting, analisis sidik jari, kromatografi lapis tipis, validasi metode

  • Antioxidant and Cytotoxicity Activities of the Fermentation Extract of the
           Endophytic Fungi from the Marine Biota of Colt Coral

    • Authors: Dede Sukandar, Nina Artanti, Ika Restu Purwanti, Tarso Rudiana, Fitriyanti Fitriyanti
      Pages: 63 - 72
      Abstract: Indonesia has the largest and most biodiverse coral reef in the world. Colt coral has not been studied and explored especially endophytic fungi associated with the coral. Endophytic fungi are highly potential for the production of antioxidant and anticancer compounds. This research aimed to study the antioxidant and cytotoxic activities of fermentation extract from endophytic fungi from colt coral. Filtrate and mycelium extracts were obtained from static and shake fermentations of isolate SKF 15. Antioxidant and cytotoxic assays were conducted by free radical scavenger 1,1-diphenyl-2-picrylhydrazyl (DPPH) and AlamarBlue methods, respectively. The result showed that FD extract provided the highest antioxidant activity with inhibition of 49.36% at 200 ppm of DPPH. Variation of fermentation time (3-21 days) demonstrated the highest activity with inhibition of 66.97% for antioxidant assay (7 days) and 81.13% for cytotoxic assay (3 days). FTIR analysis presented the existence of hydroxyl groups O-H (3452.58 cm-1), C=C groups (1668.43 cm-1); C-O hydroxyl group (1230.58 cm -1), and C-H sp3 groups (2941.44 cm-1). Based on LC-MS analysis, FD extract has a mass of m/z 305.63, [M+H]+, predicted as dihydroquercetin (C15H24O7). Keywords: Antioxidant assay, cytotoxic assay, endophytic fungi, colt coral, DPPH method, AlamarBlue method
