Abstract

Surfactant is a molecule which has hydrophilic group and a lipophilic group which can unify a mixture consisting of water and oil. Stearamide is one kind of surfactant non-ionic which has used on any aplication. This study aims to know about optimum of temperature and time on synthesis of stearamide from stearic acid and urea with zirconium (IV) chloride in mixed solvent. This study will be observed the effect of temperature and reaction time on the synthesis of stearamide surfactant from stearic acid and urea with zirconium (IV) chloride as catalyst in mixed solvent. This research was conducted at temperature of 45°C, 55°C, 65°C, 75°C, 85°C and 95°C, reaction time of 1 hr, 2 hr, 3 hr, 4 hr, 5 hr, 6 hr, 7 hr and 8 hr, substrate molar ratio at 1:6 (w/w), solvent ratio at 2:1 (v/v), weight of catalyst 3% (%w), and stirring speed at 250 rpm. Based on this research, the optimum condition to synthesis stearamide surfactant was obtained at 85 oC and reaction time at 3 hours.

Abstract

Oil palm trunks can produce quite a lot of sap water, which is approximately 10 per day for 1 month for 1 oil palm tree that is uprooted, currently, there is not much optimal processing of palm oil with an economical selling price, for this reason, it is necessary to develop functional foods. This study aims to determine whether palm sap can be used in the manufacture of symbiotic beverage products with optimum chemical, microbiological and organoleptic qualities. The study was arranged using a non-factorial Completely Randomized Design (CRD) method with 3 treatments of incubation time, namely 12 hours, 24 hours, and 36 hours with each treatment using 6 replications so that 18 experiments were carried out. The best treatment by SNI 2981:2009 was obtained at an incubation time of 24 hours, namely with a pH of 5.2, water content is 82.50%, total dissolved solids is 17.33%, the lactic acid content is 0.81%, a total lactic acid bacteria of 2.8 x 108 and produces a minimum dense texture with sufficient acidity. The organoleptic aspect of taste and aroma at 24 hours of incubation time was favored or acceptable to consumers with a taste score of 3.3b and aroma of 3.3ab (scale 1-5) in the hedonic rating test. Meanwhile, at 36 hours of incubation, consumers did not like it with a taste score of 2.2a and aroma of 2.1a. This is because the longer the fermentation time can increase the acidity of the product which causes the distinctive taste and aroma of palm sap to increase.

Abstract

Getah lontar ini dapat diolah menjadi nata dengan bantuan Acetobacter xylinum. Waktu penelitian selama 3 bulan yaitu dari bulan Mei 2021 – Juli 2021. Metode yang digunakan dalam penelitian ini adalah metode Rancangan Acak Lengkap (RAL) non faktorial dan terdiri dari 4 taraf perlakuan yaitu perlakuan A tanpa penambahan ekstrak tauge. , perlakuan B dengan penambahan ekstrak tauge. 2%, perlakuan C dengan penambahan ekstrak tauge 4%, dan perlakuan D dengan penambahan ekstrak tauge 6%. Perlakuan pembuatan nata berbahan dasar nira nira menghasilkan hasil pada perlakuan A sebesar 67,64%, perlakuan B sebesar 68,26%, perlakuan C sebesar 68,39%, dan perlakuan D sebesar 68,51%. Perlakuan pembuatan nata berbahan dasar nira nira menghasilkan kadar air pada perlakuan A sebesar 84,37%, perlakuan B sebesar 83,26%, perlakuan C sebesar 82,63%, dan perlakuan D sebesar 80,98%. Perlakuan pembuatan nata berbahan dasar nira aren menghasilkan serat kasar pada perlakuan A sebesar 7,05% dan perlakuan D sebesar 6,45%. Perlakuan pembuatan nata berbahan dasar nira aren menghasilkan kadar abu pada perlakuan A sebesar 0,615% dan perlakuan D sebesar 0,81%. Perlakuan terbaik terdapat pada perlakuan D dengan rendemen 68,51%, kadar air 80,98%, serat kasar 6,45%, dan kadar abu 0,81%. Hasil uji organoleptik menunjukkan aroma dan rasa tidak normal, sedangkan warna dan tekstur normal.

Abstract

Palm Oil Mill (POM) is a plantation company that specializes in palm oil commodities with outputs in the form of CPO (Crude Palm Oil) and PK (Palm Kernel). 12 processing stations at XYZ POM have high levels of noise, one of which is the sterilizer station which can cause hearing impairment to operators. This study aims to determine the level of noise at the sterilizer station, diagnose hearing impairment due to noise based on audiometry results, and assess the effectiveness of the implementation of the occupational health and safety management system at XYZ POM. The research method used in this study is a quantitative descriptive method using primary and secondary data. From the results of this study, it was found that the calculation of the noise level for 24 hours reached 94.9 dB. This value exceeds the threshold value for noise based on the Regulation of the Minister of Labor and Transmigration No. PER.13/MEN/X/2011 regarding the Threshold Value of Physical and Chemical Factors in the Workplace. To improve the safety and health of employees, XYZ POM implements an Occupational Health and Safety Management System (OHSMS) using the HIRARC (Hazard Identification Risk Assessment and Risk Control) method to identify potential hazards, assess risks and control them, one of which is noise by conducting regular audiometry examinations. The results of the audiometry examination on the sterilizer operator showed normal results. The implementation of the OHSMS at XYZ POM is effective, especially in controlling noise by Government Regulation No. 5 of 2012 regarding the Implementation of the Occupational Health and Safety Management System.
