UJI STABILITAS FISIK FORMULASI SEDIAAN HAIR TONIC HERBAL BUAH MENTIMUN (Cucumis Sativus L) SEBAGAI PERAWATAN RAMBUT

Hair is an essential part of the body that often experiences various problems, one of which is hair loss. Fortunately, hair loss problems can be prevented by applying a hair tonic. Many hair tonic preparations are on the market, both made from herbal and synthetic ingredients. Efforts have been made to formulate cucumber into hair tonics. This study aims to utilize herbal plants, particularly cucumber, as a remedy for hair loss. Cucumber was developed into several hair tonic formulations, and their physical stability was subsequently tested. The cucumber was extracted using the infusion method. The yielded infusion was later made into three formulas of hair tonics with three times replications for each procedure. Following the formulations, physical stability tests of the preparations were carried out, such as organoleptic, homogeneity, pH, and viscosity tests. Results of the tests showed that the trials were physically stable with a homogenous physical appearance indicating an even distribution of cucumber extract in the preparations. Further results showed average pH of 5.87, 6.12, and 6.49 with viscosity values of 0.0082, 0.0083, and 0.0085 N.S/m2, respectively. In conclusion, all the ingredients in the formulation of herbal hair tonics provided stable color and pH range that still met the requirements. Hence, this study suggested the administration of cucumber hair tonic as one of many remedies for hair ailments, specifically hair loss

The Development of Germicidal Air Purifier by Employing Ultraviolet System in Controlling Airborne Bacteria

The nosocomial infection could be acquired through airborne disease in the hospital. However, only a particular health center in Indonesia carried out a complete, cautious prevention procedure by utilizing air purifiers due to cost problems. Thus, to minimize the number of nosocomial infections related to bacterial air pollutants, excellent tools with low cost are required to address this problem. We developed an ultraviolet light system within the air purifier at a low cost and the best way to eradicate pathogenic microorganisms in the healthcare center. The study was conducted at the Faculty of Medicine, Universitas Padjadjaran, Bandung in 2009–2010. The room prototype was built from a transparent glass material with two holes at the upper corner as an inlet and outlet pipeline canal. In the middle of the pipeline circulation, a vacuum pump, ultraviolet system, and a cooler were installed so the air will initially flow through those devices before being re-circulated into the room through the pipeline's inlet hole. A fan was set on the room floor, and several ten-centimeter apart, Petri dishes containing microbial growth medium were placed. The microbial colonies from the room with and without the installed ultraviolet system in the air purifier were then compared for analysis. The result showed that an air purifier equipped with an ultraviolet system killed microorganisms 73% more effective than the air purifier without an ultraviolet system (p<0.05). In conclusion, employing an ultraviolet system within the air purifier might be effectively killed microorganisms and ultimately reduce nosocomial infection.   PENGEMBANGAN AIR PURIFIER RUANGAN DENGAN PEMANFAATAN SINAR ULTRAVIOLET UNTUK MEMBUNUH MIKROB BAWAAN UDARA Infeksi nosokomial dapat ditularkan melalui penyakit yang ditularkan melalui udara di rumah sakit. Namun, hanya rumah sakit atau pelayanan kesehatan tertentu di Indonesia yang melakukan prosedur pencegahan infeksi nosokomial secara optimal dengan memanfaatkan air purifier karena kendala biaya. Oleh sebab itu, untuk meminimalkan jumlah infeksi nosokomial yang terkait dengan bakteri pencemar udara diperlukan pengembangan air purifier yang baik dengan biaya yang murah. Kami telah mengembangkan sistem pembersih udara yang terintegrasi sinar ultraviolet dengan biaya rendah untuk mengurangi mikroorganisme patogen di ruang pelayanan kesehatan. Penelitian dilaksanakan di Fakultas Kedokteran, Universitas Padjadjaran, Bandung pada tahun 2009–2010. Prototipe ruangan dibuat dari bahan kaca transparan dengan dua lubang di sudut atas sebagai ruang instalasi pipa saluran masuk dan keluar. Pada bagian tengah sirkulasi pipa dipasang pompa vakum, sistem ultraviolet, dan pendingin sehingga udara akan mengalir melewati alat-alat tersebut sebelum disirkulasikan kembali ke dalam ruangan melalui lubang masuk pipa. Sebuah kipas dipasang pada prototipe ruangan dan setiap jarak sepuluh sentimeter ditempatkan cawan Petri yang berisi media pertumbuhan mikrob. Koloni mikrob dari ruangan model dengan dan tanpa sistem ultraviolet yang terpasang di air purifier, kemudian dibandingkan untuk dianalisis. Hasil penelitian menunjukkan bahwa air purifier yang dilengkapi sistem ultraviolet membunuh mikroorganisme 73% lebih efektif daripada air purifier tanpa sistem ultraviolet (p<0,05). Simpulan, penggunaan sistem ultraviolet dalam air purifier efektif membunuh mikroorganisme dan pada akhirnya dapat mengurangi infeksi nosokomial

The Evaluation of Loose Powder Formulation of Manihot Starch and Maydis Starch with Natural Orange Sweet Potato

Introduction: Starch is an inert additive and can be mixed with almost all drugs without causing a reaction. The use of natural dyes has a better level of safety compared to synthetic dyes. Objective: Comparing the physical evaluation of loose powder preparations made from maydis starch with manihot starch and the use of a natural dyes in the form of orange sweet potato. Method: Making orange sweet potato tuber extract using meseration and the solvent ethanol (95%): acetone (98%) (5:5). Then the powder preparation is made and a physical evaluation is carried out in the form of organoleptics, particle size distribution, homogeneity, humidity and flow rate. Results: The results show that the organoleptic test for each formula is good, the distribution of F2 particles is the best, the homogeneity test for each formula is good, the humidity test is that F1 is higher than F2 by 1.05 ± 0.01%, the flow speed test for F2 is better than F1 namely 23.53 ± 0.35 g/sec. Conclusion: Powder preparations made from Manihot starch are better than powder preparations made from Maydis starch.Latar belakang: Amilum merupakan bahan tambahan yang bersifat inert dan dapat dicampur dengan hampir semua obat tanpa menimbulkan reaksi. Penggunaan pewarna alami memiliki tingkat keamanan yang lebih baik dibandingkan dengan sintetik. Tujuan: membandingkan evaluasi fisik dari sediaan bedak tabur berbahan dasar amilum maydis dengan amilum manihot serta penggunaan pelarut alami berupa umbi jalar jingga. Metode: Pembuatan ekstrak umbi jalar jingga dengan menggunakan meserasi dan pelarut etanol (95%) : aseton (98%) (5:5). Kemudian dilakukan pembuatan sediaan bedak dan dilakukan evaluasi fisik berupa organoleptik, distribusi ukuran partikel, homogenitas, kelembapan, dan kecepatan alir. Hasil: Hasil yang diperoleh adalah uji organoleptik pada tiap formula baik, distribusi partikel F2 paling baik, uji homogenitas tiap formula baik, uji kelembapan yaitu F1 lebih tinggi dibandingkan F2 sebesar 1,05 ± 0,01%, uji kecepatan alir pada F2 lebih baik dibandingkan F1 yaitu sebesar 23,53 ± 0,35 g/detik. Kesimpulan: sediaan bedak berbahan dasar amilum manihot lebih baik dibandingkan dengan sediaan bedak berbahan dasar amilum maydis
