Biji alpukat (Persea americana Mill.) telah diteliti mengandung senyawa-senyawa metabolit sekunder yang memiliki banyak manfaat misalnya antioksidan, antimikroba, dan antifungi. Penelitian ini bertujuan untuk memformulasikan dan mengevaluasi stabilitas fisik krim ekstrak biji alpukat dengan variasi asam stearat dan TEA sebagai agen pengemulsi. Biji alpukat diekstraksi dengan menggunakan pelarut aseton 70% kemudian diformulasikan menjadi krim M/A. Formulasi krim diuji stabilitasnya dengan uji penyimpanan pada suhu tinggi (40±2ºC), suhu kamar (25º±2C), dan pada suhu rendah (4±2ºC) selama 8 minggu. Krim juga diuji stabilitasnya menggunakan uji sentrifugasi dan cycling test. Hasilnya krim F1 dan F2 berhasil mempertahankan karakteristik fisiknya seperti penampilan, pH, daya sebar dan daya lekat selama penyimpanan dan memenuhi spesifikasi pada uji sentrifugasi dan cycling test.

The exposure of sunlight consisting UV radiation has been reported to be the main cause of skin cancer and contribute about 80% of the incidence of skin damage. In an attempt to overcome this problem, antioxidant agents have been used both orally and topically. Compared to oral administration, topical route has been found to be preferred due to the direct action to the desired site. Amongst topical preparation, gel possesses numerous because it provides a cool and fresh sensation. Here, we developed gel antioxidant containing cinnamon extract as active ingredient. Cinnamon was selected as it has a very strong antioxidant activity. This study aimed to obtain the penetration profile of the antioxidant gel of cinnamon extract prepared from two different hydrocolloid agents. The gels were made using various concentrations of Carbopol 940 and NaCMC. The prepared gels were further characterized for their antioxidant capacities using the DPPH free radical scavenging method and their total phenolic contents using the spectrophotometric method. The formulation possessing the strongest antioxidant capacity was continued for ex vivo penetration study using Franz diffusion cells. The results exhibited that the total phenolic value of the cinnamon extract obtained was 908.38 ± 6.54 mg GAE/g extract. The penetration percentages for the formula with Carbopol and NaCMC bases were 53.310 ± 1.217% and 27.969 ± 1.151%, respectively, and the retention percentages were 28.495 ± 0.031% and 18.356 ± 0.191%, respectively. Based on these findings, we concluded that cinnamon extract could potentially be formulated into antioxidant gel preparations and formulas based on Carbopol showed the best penetration profile.

Metode sonic bloom merupakan pengembangan ilmu pengetahuan dan teknologi di bidang pertanian yang memanfaatkan gelombang suara dengan frekuensi tinggi tanpa merusak lingkungan. Aplikasi sonic bloom berpotensi untuk meningkatkan pertumbuhan pada tanaman yang ditunjukkan dengan adanya peningkatan pembukaan stomata, perkecambahan, pertumbuhan (tinggi tanaman, tinggi dan diameter batang, panjang dan lebar daun, dan panjang akar) serta produktivitas. Metode sonic bloom yang efektif menggunakan bunyi dengan rata-rata intensitas bunyi 65-75 dB, frekuensi bunyi 3-5 kHz dan lama pemaparan 3 jam per hari serta variasi jenis musik. Gelombang bunyi ini menginduksi pembukaan stomata yang berdampak pada peningkatan penyerapan CO2, H2O dan unsur-unsur hara oleh tanamanThe sonic bloom method is the development of science and technology in agriculture that utilizes high-frequency sound waves without damaging the environment. Sonic bloom application was potential to increase plant growth as indicated by an increase in stomata opening, germination, growth (plant height, height and diameter of stem, length and width of leaf, and root length) and productivity. An effective sonic bloom method used sound with an average sound intensity of 65-75 dB, a sound frequency of 3-5 kHz and an exposure time of 3 hours per day as well as a variety of types of music. This sound wave induced the opening of stomata which had an impact on increasing the absorption of CO2, H2O and nutrients by plants.

Virgin Coconut Oil (VCO) yang merupakan salah satu produk olahan kelapa yang memiliki banyak manfaat kesehatan sulit dikonsumsi secara langsung karena rasanya yang berminyak (oily). Oleh karena itu, untuk membuatnya enak dikonsumsi, VCO dibuat dalam bentuk minuman emulsi. Pada penelitian ini, minuman emulsi VCO ditambahkan dengan jahe merah dan sereh yang bertujuan untuk menyelidiki pengaruh penambahan jahe merah dan sereh pada karakteristik fisik, kimia, aktivitas antioksidan, dan tingkat kesukaan panelis terhadap minuman emulsi VCO. Konsentrasi jahe merah dan sereh divariasikan: 100% jahe merah, 100% sereh, 50% jahe merah : 50% sereh, 75% jahe merah : 25% sereh, dan 25% jahe merah : 75% sereh. Hasil menunjukkan bahwa konsentrasi jahe merah dan sereh mempengaruhi warna minuman emulsi VCO yang dihasilkan. Penggunaan gum arab (7%) menghasilkan minuman emulsi VCO yang stabil selama waktu pengamatan 7 hari. Total gula (% sukrosa) berkisar pada 26,00%-28,67%. Total fenol dan bilangan peroksida minuman emulsi berkisar dari 20,92 – 28,61 mg GAE/ g sampel dan 0,08-0,79 mg ekuivalen O2/kg. Pada konsentrasi 15 ppm, aktivitas antioksidan minuman emulsi berkisar antara 58,58% - 71,20%. Minuman emulsi dengan penambahan 100% jahe merah paling disukai dalam aroma, warna, dan penampakannya, sedangkan minuman emulsi dengan penambahan 75% jahe merah dan 25% sereh yang paling disukai rasanyaVirgin Coconut Oil (VCO) as one of the coconut products with many health benefits hard to be consumed directly because of its oily taste. Therefore, to make it more tastier to consume, VCO will be made in form of emulsion drink. In this research, VCO emulsion drink will be added with red ginger and lemongrass to investigate the addition effect of these spices on the physical, chemical characteristic, antioxidant activity, and panelist preference rate of its emulsion drink. The concentrations of red ginger and lemongrass were varied : 100% red ginger, 100% lemongrass, 50% red ginger : 50% lemongrass, 75% red ginger : 25% lemongrass, and 25% red ginger : 75% lemongrass. The result shows that the concentration of red ginger and lemongrass affected the color of the emulsion drink. The addition of arabic gum (7%) produced a stable emulsion drink during the observation time of 7 days. The sucrose percentage of the emulsion drink is 26,00% to 28,67%. The average of total phenol and peroxide numbers in the emulsion drinks was 20,92 to 28,61 mg GAE /g sample and 0,08-0,79 mg equivalent O2 / kg. At a concentration of 15 ppm, the antioxidant activity of emulsion drinks ranged from 58,58% - 71,20%.

Tujuan dari penelitian ini mengukur indeks aterogenik plasma (IAP) dan indeks Castelli (IC) dari mencit model yang diinduksi minyak trans (MT). Sebanyak 16 ekor mencit galur DDY dibagi menjadi 4 kelompok yaitu mencit yang diinduksi 20% minyak trans (MT20), 40% minyak trans (MT40) dan 60% minyak trans (MT60) dan kontrol (K). Persentase minyak trans diberikan berdasarkan dari total energi konsumsi pakan harian. Minyak trans diberikan per oral sehari sekali selama 70 hari. Darah diambil pada hari ke-70 dari vena lateral ekor tikus untuk mengukur profil lipid plasma yaitu kolesterol total, trigliserida (TG), High Density Lippoprotein (HDL) dan Low Density Lipoprotein (LDL) plasma menggunakan alat uji cepat Lipid Pro®. Nilai Indeks Aterogenik Plasma (IAP) yaitu log (TG/HDL) dan Indeks Castelli (IC) yaitu LDL/HDL. Hasil pengkuran profil lipid plasma menunjukkan kolesterol total, trigliserida, HDL dan LDL plasma pada kelompok MT meningkat secara nyata dibandingkan kontrol (sig<0,05). Nilai IA pada mencit yang diberi minyak trans berbeda nyata dari kontrol (sig<0,05) dan memiliki risiko tinggi. Nilai IC pada mencit yang diberi minyak trans berbeda nyata dari kontrol (sig<0,05) dan memiliki risiko sedang-tinggi. Minyak trans meningkatkan nilai indeks aterosklerosis dan indeks resiko koroner mencit.Coronary Heart Disease (CHD) is a "silent killer" disease. Various studies were developed through an animal model approach to studying CHD. Cooking oil that is used repeatedly can increase levels of free fatty acids which have a negative impact on health, especially the heart and vessels. The aim of this study was to measure the plasma atherogenic index (IAP) and Castelli index (IC) of trans oil-induced model mice (MT). A total of 16 DDY mice were divided into 4 groups, namely mice induced with 20% trans oil (MT20), 40% trans oil (MT40) and 60% trans oil (MT60) and control (K). The percentage of trans oil is given based on the total energy consumption of the daily feed. Trans oil is given orally once a day for 70 days. Blood was taken on the 70th day from the lateral vein of the rat tail to measure the plasma lipid profile, namely total cholesterol, triglycerides (TG), High Density Lippoprotein (HDL) and plasma Low Density Lipoprotein (LDL) using the Lipid Pro® rapid test kit. The Plasma Atherogenic Index (IAP) values are log (TG / HDL) and the Castelli Index (IC) is LDL / HDL. The results of measuring the plasma lipid profile showed that plasma total cholesterol, triglycerides, HDL and LDL in the MT group increased significantly compared to the control (sig<0,05). The IA value in mice treated with trans oil was significantly different from the control (sig<0.05) and had a high risk. The IC value in mice treated with trans oil was sig
