Abstract

Education Of The Hazards Of Cholesterol And The Benefits Of Avocado Seed Coffee That ContradictKnowledge about the dangers of cholesterol that is too high in the human body is needed by the community, because high cholesterol levels will cause hypertension, blockage of blood vessels in the brain and heart. In overcoming this, people generally use treatment to reduce total cholesterol levels in the body with drugs available in the market. However, these drugs have side effects that are quite dangerous for the body, causing damage to other organs/complications with other diseases. Therefore it is necessary to hold an education about the dangers of cholesterol and cholesterol prevention from herbs which in the future are expected to have a similar effect as drugs on the market to lower cholesterol but have low side effects. One of the selected herbal ingredients is avocado seeds which are usually thrown away by the general public. In this counseling, avocado seeds are first processed into coffee and made into pudding for easy and comfortable consumption by anyone. Extension activities were carried out to 24 residents in the Kupang Krajan area of Surabaya. From counseling about the dangers of cholesterol disease which includes definitions, causative factors, clinical symptoms and methods of prevention as well as material about making avocado seed coffee and avocado seed pudding, questionnaires were filled out before and after the delivery of the material. The result of this counseling had a significant effect on the understanding of the counseling participants with an increase in the level of understanding by 26% after being tested statistically using the SPSS paired t-test method with a significant value of 0.000 <0.05. This means that this outreach activity is very useful for participants.Pengetahuan tentang bahaya kolesterol yang terlalu tinggi pada tubuh manusia sangat diperlukan masyarakat, karena kadar kolesterol tinggi akan menyebabkan hipertensi, penyumbatan pembuluh darah otak dan jantung. Dalam mengatasi hal tersebut, umumnya masyarakat menggunakan pengobatan untuk menurunkan kadar kolesterol total di tubuh dengan obat yang tersedia di pasaran. Namun obat-obat tersebut memiliki efek samping yang cukup berbahaya juga bagi tubuh sehingga menyebabkan adanya kerusakan pada organ lain/komplikasi dengan penyakit lainnya. Maka dari itu perlu diadakannya suatu penyuluhan tentang bahaya kolesterol dan pencegahan kolesterol dari herbal yang dikemudian hari diharapkan dapat memiliki efek yang serupa seperti obat yang ada pada pasaran untuk menurunkan kolesterol tetapi memiliki efek samping yang rendah. Salah satu bahan herbal yang dipilih adalah biji alpukat yang biasanya dibuang begitu saja oleh masyarakat umum. Pada penyuluhan ini biji alpukat diolah terlebih dahulu menjadi kopi dan dibuat menjadi puding agar mudah dan nyaman dikonsumsi oleh siapa pun. Kegiatan penyuluhan dilakukan kepada 24 warga di daerah Kupang Krajan Surabaya. Dari penyuluhan mengenai bahaya penyakit kolesterol yang meliputi definisi, faktor-faktor penyebab, gejala klinis dan cara pencegahannya serta materi tentang pembuatan kopi biji alpukat dan puding biji alpukat, dilakukan pengisian kuesioner sebelum dan sesudah penyampaian materi. Hasilnya penyuluhan ini berpengaruh secara signifikan terhadap pemahaman peserta penyuluhan dengan kenaikan tingkat pemahaman sebesar 26% setelah diuji secara statistik menggunakan SPSS metode paired t-test dengan nilai signifikan 0.000 <0.05. Hal ini berarti kegiatan penyuluhan ini sangat bermanfaat untuk para peserta.   Kata kunci : Biji Alpukat, Kolesterol, Kopi, Surabaya

Abstract

Diabetes mellitus type 2 is the most common degenerative disease in Indonesia, so that the regulation of food intake is important. Food sources of carbohydrates with a low glycemic index (GI) can control blood sugar levels. GI is the rate at which food is absorbed into blood glucose. Purple sweet potato has a low GI so it is suitable as an alternative source of carbohydrates. Different cooking processes can affect the GI of the purple sweet potato, the frying technique produces the lowest GI compared to the boiling or baking technique. The manufacture of hybrid purple sweet potato flour is able to replace the use of wheat flour for processed food products. Hybrid purple sweet potato flour can increase the antioxidant content.

Abstract

The direct compression method is one of the most popular tablet manufacturing methods because of its efficiency. However, direct compression requires excipients with good flow and compressibility properties. The requisite for materials with these properties can be overcome by using co-processed excipients. The co-processed excipient combines two or more types of excipients that aim to improve flow properties and compressibility. This study aims to determine the effect of differences in Avicel PH-102 (F1=10%; F2=15%) and Primogel (F3=4%; F4=8%) variations as disintegrants on the characteristics of co-processed excipients. The excipients include lactose as filler, Avicel PH-102 or primogel as a disintegrant, and PVP K-30 as a binder. The method of preparation co-processed excipient used was wet granulation. The results showed that the granule flow rate was F1=14.62 g/second, F2=11.30 g/second, F3=19.31 g/second, and F4=11.57 g/second. The angle of repose of the granules was F1=11.30˚, F2=19.24˚, F3=13.97˚, and F4=20.78˚. Compressibility and Hausner granule ratio F1=12% and 1.13; F2=17.81% and 1.21; F3= 7.12% and 1.07; and F4 = 16.51% and 1.19. Percentage of moisture content of granules F1=4%, F2=3.67%, F3=3%, and F4=3.67%. Percentage of fines granule F1 = 18.42%, F2 = 9.14%, F3 = 4.06%, and F4 = 2.65%. The evaluation results were statistically tested using the SPSS one-way ANOVA or Kruskall Wallis. All formulas in this study were able to produce co-processed excipients that met the requirements, and there were significant differences except for the water content parameter.

Abstract

Whiteleg shrimp (Litopenaeus vannamei) on the market are processed or sold only to take part in the meat. The head, shell, and tail are thrown away without any prior processing. Underutilized waste causes environmental problems. An alternative to overcome this environmental disturbance phenomenon is to utilize shrimp shells containing chitin and subsequently transformed into chitosan that can be applied in various fields. Chitosan has poor solubility in water but high permeability; thus, improve bioavailability is accomplished by making solid dispersions. This study aims to formulate and evaluate the solid dispersion tablet using chitosan extract from L. vannamei as an active agent with PVP K-30 as a carrier. The formulation divided into three groups, that was F1 (chitosan : PVP K-30 = 1 : 1 solid dispersion), F2 (chitosan : PVP K-30 = 1 : 3 solid dispersion), and F3 (pure chitosan). The result of chitosan solid dispersion was molded into tablets by the direct compression method. The tablets were evaluated by weight and size uniformity, hardness, friability, and disintegration time. All the formulas by weight and size uniformity as well as disintegration time fulfill the requirements. The hardness of the tablets from F3 with 4,275 kg was the best from F1 and F2. By statistic analytical from weight uniformity, hardness and disintegration time give significant difference with sig. <0.05.

Abstract

Climate change has negative impacts throughout the countries in the world, especially Indonesia, which has a tropical climate. Successful aging can be achieved by building individual self-confidence through prevention and skin aging. Indonesia is a producer of milkfish waste, reaching 5.4 tons/year, which is in line with the increasing center of "Otak-otak" milkfish souvenirs found in Gresik. The waste, especially fishbones, can be synthesized into collagen. The characteristic fishbone collagen waste are in the form of large porous sheets, while particle size is an essential factor in the absorption effectiveness of cosmetics. Therefore, Nanoemulgel is able to overcome this problem. This research aims to produce best collagen nanoemulgel from milkfish bone by physical evaluation with varying ratios of surfactant: cosurfactant in collagen nanoemulgel. The research method was done experimentally by comparing the components Tween 80: PEG 400 F1 (30:30), F2 (40:20), and F3 (35:15) through qualitative and quantitative physical characteristics using one-way anova. Evaluations whose results differ significantly are pH on the 7th day, spreadability, and viscosity. Research results show F2 is the best formula and meets physical stability specifications : particle size 3.89 nm, PDI 0.1906, zeta potential -0.2 mV, pH 4.7±0.04, viscosity 890.1± 4.26 cps, spreading 5.93±0.23 cm.
