Essential oil production in the market is very diverse with various brands labeled as antioxidants that have gained more attention in the society recently. The purpose of this study was to analyze limonene and other antioxidants content of the essential oils in the market compared to homemade virgin coconut oil. The method used was Gas Chromatography-Mass Spectrometry (GC-MS) and Fourier-transform infrared (FTIR) Spectroscopy. The infrared spectrogram showed the presence of alkanes and esters respectively at wave numbers of 3000-2850 and 1750-1730 cm-1. Chromatogram results showed the presence of limonenecompounds and some antioxidants with a fairly good separation in the several types of oils, which was not detected in the homemade virgin coconut oil.

Sabun merupakan sediaan yang paling banyak digunakan yang bersifat sebagai pembersih dan anti bakteri bagi tubuh. Penggunaan VCO sebagai basis sabun padat transparan karena VCO karena kandungan asam lemak  yang  menguntungkan  kulit Proses pembuatan sabun dengan metode panas, dengan basis VCO yang dibuat metode penggaraman. Evalusi standar mutu meliputi uji organoleptis, uji tinggi busa dan stabilitas busa Hasil uji standar mutu sifat fisik yaitu uji organoleptik, uji tinggi busa dan stabilitas busa memenuhi standar mutu sediaan sabun yang beredar dipasaran, tidak terjadi perbedaan mutu fisik yang bermakna antara sabun padat transparan minyak sereh wangi yang diformulasi  dengan sabun padat transparan yang beredar.

AbstrakPenelitian ini bertujuan untuk mentransformasi kitosan menjadi carboxymethyl chitosanyang selanjutnya diubah menjadi carboxymethyl chitosan urea glutarat (CMChi-UGLU) dan kemudian diaplikasikan sebagai katalis terfluidakan untuk sintesis biodiesel. Selain itu, penelitian ini juga bertujuan untuk menentukan aktivitas katalitik katalis CMChi-UGLU. CMChi-UGLU yang diperoleh dikarakterisasi dengan menggunakan Fourier Transform Infra Red(FTIR) sedangkan biodiesel yang diperoleh dikarakterisasi dengan menggunakan Gas Chromatography-Mass Spectrometry (GC-MS). Sintesis biodiesel dilakukan dengan menggunakan kolom fluidisasi yang diisi denganVirgin Coconut Oil dan metanol (1:60) serta katalis CMChi-UGLU sebanyak 10% b/b minyak selama 90 menit dan pada suhu 65-70°C. Hasil penelitian menunjukkan bahwa aktivitas katalitik katalis CMChi-UGLU adalah 80,046%, hasil ini lebih tinggi dibandingkan katalis chitosan yaitu 40,023%. Kata kunci: kitosan, CMChi-UGLU, fluidisasi, aktivitas katalitik  AbstractThis study aims to transforming chitosan into carboxymethyl chitosan which is converted into carboxymethyl chitosan urea glutaric acid (CMChi-UGLU) that will be used as a fluidized catalyst for synthesis biodiesel. In addition, this study aims to determining the catalytic activity of CMChi-UGLU. CMChi-UGLU is characterized by Fourier Transform Infra-Red(FTIR) while biodiesel is characterized by Gas Chromatography-Mass Spectrometry (GC-MS). Synthesis of biodiesel is performed using fluidization column which filled with virgin coconut oil and methanol (1:60) and also heterogeneous catalyst CMChi-UGLU as many as 10% of oil weight on condition within 90 minutes at temperature 65-70°C. The result of synthesis of biodiesel showed that the catalytic activity of CMChi-UGLU is 80,046%, this result is higher than uses chitosan which it’s catalytic activity is 40,023%. Keywords: chitosan, CMChi-UGLU, fluidization, catalytic activity

Preparation of mucoadhesive patch film containing Virgin Coconut Oil (VCO) has been made as a medium to inhibit the growth of Streptococcus mutans. This research was conducted to make patch film which meets the standard physical characteristic of patch mucoadhesive film. The physical characteristic is weight uniformity, thickness, folding endurance resistance, swelling index and pH of the patch solution. The presence of fatty acids which trapped in patch was analyzed with Gas Chromatography Mass Spectrometry (GC-MS). The result showed that the patch film has uniformity value of weights ranging from 0.04 to 0.17 g. The thickness of patch was 0.53 to 0.61 mm and have folding endurance resistance more than 300 times. Swelling index for each patch increase in the 5th minutes and decrease in the 10th minutes. The surface pH of the patch almost close to pH 7. GC-MS chromatogram showed that lauric acid (C8), meristic acid (C14), palmitic acid (C16) and linoleic acid (C18) were trapped in the patch. The patch film containing VCO can inhibit the growth of Streptococcus mutans with inhibition zone of 157.30 ±1.088 mm2.

Virgin Coconut Oil (VCO) adalah bahan alami yang memiliki sifat antimikroba (antivirus, antibakteri, dan antijamur). Sehingga VCO dapat memberikan efek pengawet pada bahan makanan, salah satunya adalah roti manis. Penelitian ini dilakukan untuk mengevaluasi pengaruh VCO terhadap karakteristik (fisik dan kimia) dan umur simpan roti manis. Roti manis dianalisis secara fisik (tekstur dan porositas) dan kimia (kadar air, kadar abu, kadar lemak, kadar protein, dan kandungan karbohidrat), dan analisis umur simpan dengan FFA, uji organoleptik dan jamur setiap dua hari selama delapan hari penyimpanan di suhu ruang. Variasi perlakuan roti manis adalah dari rasio konsentrasi VCO: margarin: mentega, K (0%: 8%: 8%); A (4%: 6%: 6%); B (8%: 4%: 4%), C (12%: 2%: 2%); D (16%: 0%: 0%). Hasil penelitian menunjukkan bahwa VCO tidak memiliki pengaruh yang signifikan terhadap karakteristik fisik dan karakteristik kimia roti manis. Namun, VCO berpengaruh signifikan terhadap kadar air roti manis yang dihasilkan, roti manis K memiliki kadar air tertinggi (22,36%) dan berbeda dengan sampel roti manis lainnya. VCO secara efektif menghambat pertumbuhan jamur di roti manis pada konsentrasi 8%, 12%, dan 16%. Roti manis K dan A memiliki masa simpan 4 hari, sedangkan roti manis B, C, dan D memiliki masa simpan 6 hari.Kata kunci: VCO, roti manis, karakteristik, umur simpanABSTRACTVirgin Coconut Oil (VCO) is a natural ingredient that has antimicrobial (antiviral, antibacterial, and antifungal) properties. So that VCO can provide a preservative effect on food ingredients, one of which is sweet bread. This research was conducted to evaluate the effect of VCO on characteristics (physical and chemical) and shelf life of sweet bread. Sweet bread was analyzed physically (texture and porosity) and chemistry (moisture content, ash content, fat content, protein content, and carbohydrate content), and shelf life analysis with FFA, organoleptic and mold tests every two days for eight days of storage at ambient temperature. Treatment variations of sweet breads is from the ratio of the concentration of VCO: margarine: butter, K (0%: 8%: 8%); A (4%: 6%: 6%); B (8%: 4%: 4%), C (12%: 2%: 2%); D (16%: 0%: 0%). The results showed that VCO did not have a significant effect on the physical characteristics and chemical characteristics of sweet bread. However, the VCO has a significant effect on the water content of the sweet bread produced, sweet bread K has the highest moisture content (22,36%) and it is different from other sweet bread samples. VCO effectively inhibits the growth of sweet bread mold at concentrations of 8%, 12%, and 16%. K and A sweet bread has a shelf life of 4 days, while sweet breads B, C, and D have a shelf life of 6 days.Keywords: VCO, sweet bread, characteristics, shelf life

Introduction: The role of virgin coconut oil in the treatment of allergic rhinitis is controversial. Thus, the aim of the present study is to determine the effects of virgin coconut oil ingestion, in addition to standard medications, on allergic rhinitis. We also studied the side effects of consumption of virgin coconut oil. Methods: Fifty two subjects were equally divided into test and control groups. All subjects received a daily dose of 10mg of loratadine for 28 days. The test group was given 10ml of virgin coconut oil three times a day in addition to loratadine. The symptoms of allergic rhinitis were scored at the beginning and end of the study. Results:, the symptom score were divided into nasal and non-nasal symptom scores. Sneezing score showed a significant difference, however the score was more in control group than test group, indicating that improvement in symptom was more in control group. The rest of the nasal symptom and non-nasal symptom score showed no significant difference between test and control groups. Approximately 58% of the test subjects developed side effects from consumption of virgin coconut oil, mainly gastrointestinal side effects. Conclusion: In the present study, ingestion of virgin coconut oil does not improve the overall and individual symptoms of allergic rhinitis, furthermore it has side effects.
