A Potential and Characteristics Identification of Nanoemulsions Production from CPO using Sonication Methode
No full textEmulsions are colloidal dispersions of liquids/phases/droplets that do not mix with other liquids, which generally consist of an oil phase and an aqueous phase. Based on the dispersed phase particle size, stability, and appearance emulsions are divided into three categories: conventional emulsions, microemulsions, and nanoemulsions. Sonication is one of the most widely developed methods as it is proven to be more effective in producing nano-sized particles when compared to conventional methods. This research is a preliminary research to determine the best formulation for the preparation of emulsion from CPO using sonication method and to determine the characteristics of CPO emulsion as well as to develop the potential usefulness and economic value of CPO. The variations were 1, 3, 5, 7, 9% (v/v) CPO with distilled water and 5 ml of tween 80 as surfactant. The smallest particle size was obtained in the variation with the amount of CPO 1 ml, which was 188.4 nm and the PDI (Polydispersity Index) value was 0.663, indicating that the particles produced were heterogeneous. Thus, the emulsion produced had a pH between 4-5, a viscosity of about 1 cp, and had good stability during the 14 days of observation
Synthesis of Poly Lactic Acid from Lactic Acid Using Direct Polycondensation Method Using Al(DS)3 and AlCl3 Catalysts
No full textPoly Lactic Acid (PLA) is a type of polymer that is widely researched because it can meet the requirements for biodegradable polymers and can be used in several of applications. Making PLA using the direct polycondensation method is carried out in 3 process stages, namely dehydration, polycondensation and recrystallization. Dehydration was carried out at 130℃ for 1 hour. Polycondensation was carried out at varying temperatures of 160℃, 180℃ and 200℃ with a concentration of 0.15% for 6 hours. In the meantime, 50 ml of methanol was added, and vacuum conditions were used to carry out the recrystallization process. After that, the viscosity method was used to determine PLA\u27s molecular weight. The highest molecular weight and other properties of PLA, such as its functional groups and thermal behavior, are the aim of this study. The findings of the study indicate that PLA has its maximum molecular weight at 180°C, where it is 15576 gr/mol for PLA+Al(DS)3 and 10771 gr/mol for PLA+AlCl3. The PLA+Al(DS)3 and PLA+AlCl3 spectra display the same bands in the stretching and bending vibration modes, according to the FTIR test. Meanwhile, in the TGA analysis, the highest decomposition was shown by PLA+Al(DS)3 at a temperature of 365℃
Analisis Postur Kerja Menggunakan Metode Rapid Upper Limb Assessment (RULA) pada Bilik Las SMAW
No full textPoliteknik Perkapalan Negeri Surabaya (PPNS) is a vocational training institution that focuses on shipping and marine affairs. Through its education and training programs, PPNS provides in-depth knowledge of transportation engineering, including welding techniques. Welding plays an essential role in connecting and strengthening ship structures in the marine industry. However, welding can lead to the risk of occupational musculoskeletal disorders. This research describes the ergonomical hazards that may arise in PPNS welding operations. The causes of those are repetitive hand and arm movements and poor posture. Therefore, the purpose of this research is to identify occupational musculoskeletal hazards in the PPNS work environment and provide a basis for changes in workplace design to reduce these risks. The purpose of this study is to determine the possible risk of ergonomics by using GOTRAK and RULA for students who perform welding operations in the PPNS welding workshop through work practice. The research shown that the final score of RULA is 7 (high risk), which means it needs to be redesign
Pengaruh Ukuran Bahan terhadap Yield pada Proses Ekstraksi Minyak Kayu Putih dengan Metode Microwave Hydrodiffusion and Gravity
No full textTumbuhan kayu putih (Melaleuca leucadendra Linn.) termasuk dalam keluarga Myrtaceae. Minyak kayu putih biasanya dihasilkan dari penyulingan tradisional (konvensional) yang proses ekstraksinya memerlukan waktu dan energi yang cukup banyak. Bukan hanya itu penyulingan secara konvensional memerlukan pelarut kimia yang cukup banyak dengan harga yang mahal. Sehingga pada penelitian ini dilakukan pengembangan dari metode konvensional yaitu metode microwave hydrodiffusion gravity (MHG) yang tidak membutuhkan pelarut. Tujuan dari penelitian ini adalah menetapkan ukuran bahan yang paling optimal pada ekstraksi menggunakan metode MHG. Bahan yang digunakan pada penelitian ini adalah daun kayu putih pada kondisi bahan tanpa pengeringan dan dengan pengeringan. Variabel ukuran daun yang digunakan adalah 1 cm; 1,5 cm; dan 2 cm. Dari hasil penelitian diperoleh bahwa kondisi operasi yang optimal untuk ekstraksi minyak kayu putih menggunakan metode MHG pada bahan kering dengan ukuran 1 cm menghasilkan yield sebesar 2,96%. Pada bahan tanpa pengeringan dengan bentuk daun cacah menghasilkan yield sebesar 1,79%
