Transdermal patch was chosen to manage the delivery system of the antibacterial compound in cassava leaves, which is rutin, that is hydrophilic. Plasticizer is one of the additional ingredients of transdermal patches that can maintain the bioavailability of a drug. Transdermal patch formulation with active cassava leaf ethyl acetate fraction ingredients and 3 variations of PEG-400 concentration…
This research aimed to determine the effect of method and duration of fermentation on the physicochemical and sensory characteristics of cassava (Manihot esculenta) tape. This research used a Factorial Completely Randomized Design (CRD) with two treatment factors. The first factor was the fermentation method consisting of three levels (A1 = aerobic fermentation, A2 = facultative anaerobic ferme…
Cassava leaves (Manihot Esculenta Crantz.) is proven to contain secondary metabolites, including flavonoids such as rutin, which demonstrated antibacterial capabilities. The deformability and elasticity of transethosomes penetrated the stratum corneum and increased the transfer of active substances in skin permeability. This research aimed to determine the optimum transethosome formula from var…
Daun singkong (Manihot Esculenta Crantz.) mengandung senyawa metabolit yang dihasilkan salah satunya flavonoid terdapat rutin dikenal sebagai quercetin-3-rutinoside yang berpotensi sebagai anti acne. Etosom memiliki kemampuan sebagai pengantar untuk meningkatkan transfer bahan aktif melalui kulit dengan lebih efisien dalam hal permeabilitas kulit. Tujuan dari penelitian ini adalah mengetahui fo…
Cassava leaves contain rutin compounds which are flavonoid derivatives that have antibacterial properties. Transdermal patch preparation was chosen for the ethyl acetate fraction of cassava leaves because it can produce effective preparations to deliver active compounds through the skin to reach the systemic. This study aims to obtain the best formula with plasticizer concentration in transderm…
Fraksi etil asetat daun singkong mengandung senyawa rutin yang efektif menghambat pertumbuhan bakteri Staphylococcus aureus. Penelitian ini bertujuan mengetahui variasi konsentrasi kalsium klorida sebagai crosslinker terhadap transdermal patch yang dihasilkan dan mengetahui aktivitas antibakteri sediaan transdermal patch. Polimer yang digunakan pada penelitian ini adalah kitosan dan natrium alg…
One of the main problems on cassava production decline is mealybug pests (Ferrisia virgata Cockerell) that can damage parts of plant such as shriveled leaves and stunted shoots to resemble flowers or called bunchy tops. Presence of mealybugs in the early life period is a treat that cassava plant death causing. This study aims to determine the population dynamics of mealybugs on cassava plants a…
This research aims to modify the material intake funnel so that the cassava to be cut does not leave residue and operator safety when operating the cassava chopper machine. This research was conducted from March 2020 to October 2020. This research used a cassava chopper using a blade plate rotation speed of 795.5 rpm which was measured using a tachometer. The materials used were cassava (Maniho…
Tujuan penelitian ini adalah mengetahui waktu pengeringan yang tepat dan mempelajari pengaruh penyimpanan terhadap karakteristik sayur daun singkong tumbuk kering. Penelitian ini dilaksanakan di Laboratorium Kimia Hasil Pertanian dan Laboratorium Mikrobiologi Hasil Pertanian Jurusan Teknologi Pertanian, Fakultas Pertanian, Universitas Sriwijaya, Indralaya pada Bulan September 2011 hingga Maret …
The cassava chopper machine is a tool used to facilitate the process of slicing cassava in order to obtain good quality cassava chips. Many factors affect the performance of the cassava chopper machine, one of which is the number of blades used and the rotational speed of the disc. This study aims to determine the effect of number of kinives and the disk rotation speedon ther performance of the…
This research was aimed to find out the efficiency of the performance of oil spinner machine to improve the quality of cassava chips. This research has been conducted from January 2021 to March 2021 at the Laboratory of Agricultural Machinery and workshop, Faculty of Agriculture, Sriwijaya University, Indralaya, South Sumatra. The method used was Factorial Randomized Block Design (RAKF) with th…
The purpose of this study was to determine the effect of cassava size and heating on physical, chemical and sensory properties. This research was conducted in October 2019 until July 2020 at the Laboratory of Agricultural Product Chemistry, Laboratory of Agricultural Product Microbiology and Sensory Laboratory of the Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya Unive…
Bertambahnya jumlah kendaraan bermotor diikuti semakin meningkatnya jumlah konsumsi bahan bakar. Kenyataannya, ketersediaan bahan bakar minyak bumi semakin mengalami penurunan. Bahan bakar yang berasal dari minyak bumi tidak bisa diperbaharui. Untuk itu perlu adanya bahan bakar alternatif yaitu bahan bakar nabati atau bioetanol. Bioetanol diperoleh dari bahan baku singkong dengan memfermentasi …
