Dalam rangka meningkatkan kinerja program pengabdian kepada masyarakat di lingkungan kecamatan Cimanggis Depok, dalam memberikan pelayanan pelatihan pembuatan larutan pembersih lantai, maka Fakultas Teknologi Industri Universitas Jayabaya melaksanakan pengukuran “Kepuasan Masyarakat”. Survei Kepuasan Masyarakat bertujuan untuk mendapatkan feedback/ umpan balik atas kinerja/ kualitas pelayanan yang diberikan kepada masyarakat guna perbaikan/ peningkatan kinerja/ kualitas pengabdian secara berkesinambungan. Program Pelatihan Pembuatan Pembersih Lantai Kepada Penduduk Pada Usia Produktif (Belum Bekerja) di Kecamatan Cimanggis Depok, perlu dilakukan survei kepuasaan pelanggan agar dapat diketahui tingkat kualitas materi pelatihan dan pelayanan program pengabdian kepada masyarakat sebagai bahan untuk menetapkan kebijakan dalam rangka meningkatkan kualitas pelayanan selanjutnya.Dari survei yang dilakukan diperoleh rata-rata nilai indeks 3,85 dari 7 variabel yang berada dalam nilai interval 3,26 – 4,00 atau nilai interval konversi sebesar nilai indeks x nilai dasar = 3,85 x 25 = 96,23% yang berada dalam nilai interval konversi antara 81,26 – 100,00. Angka ini menunjukkan bahwa Mutu Pelayanan program Pengabdian Kepada Masyarakat mendapatkan nilai A yang berarti Kinerja Unit Pelayanan PKM “Sangat Baik/Sesuai”. Namun perlu adanya perbaikan di keandalan (reliability) para narasumber dalam menyiapkan dan menyampaikan materi pelatihan karena nilai indeks yang lebih rendah dari variabel lainnya yaitu 3,61 atau 90,28%.
Trimethylolpropane esters were synthesized by transesterification of calophyllum methyl esters and trimethylolpropane using a calcium oxide as the catalyst. The results showed that the optimal reaction conditions (temperature: 130 0 C, reaction time: 5 h, reactant molar ratio: 3.9:1, catalyst amount 3%w/w, and formed trimethylolpropane ester of 79.0% were obtained. The basic physicochemical properties of the trimethylolpropane esters were the following : kinematic viscosities of 56.40 cSt and 8.8 cSt at 40 0 C and 100 0 C, viscosity index 193, flash point 218 0 C and pour point -3 0 C. So Methyl esters of fatty acids of would callophylum methyl ester is good raw material for the synthesis of lubricating oils.
Isoeugenyl acetate is an eugenol derivative product in the form of white crystalline powder, it smells like vanilla, and has a spicy, hot and slightly sweet taste. Isoeugenyl acetate used in various industries, such as pharmaceuticals, cosmetics, food and beverages, cigarettes, pesticides, fishery, mining, packaging and other chemical industries. However, there is a problem in the product specification that is unacceptable to the consumer that is the acid number is high, it;s make of smell of acids in the product. Standart product of isoeugenyl acetate has an acid number of 0.5 mgKOH/g. The research method used to decrease the acid number in isoeugenyl acetate is washing process. The aim of of this research are to obtain temperature, stirring time and the concentration of sodium bicarbonate. The condition of washing process of isoeugenyl acetate were obtained at temperature 35oC, stirring time 100 minutes, and concentration sodium bicarbonate 3,5%. In these conditions acid number of 0.4594 mgKOH/g and the drying time of the isoeugenyl acetate product of 7 hours.
Keywords: Isoeugenyl acetate, sodium bicarbonate, Acid number
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
