Abstract

Fleas (Pediculus humanus capitis) is one of the little parasites that live by sucking blood from a human head. While sucking blood, the flea secretes a secretion that irritate the skin tissues it causes a massive itch. Fleas can be treated by chemical drugs like 1 % permethrin, but it did have side effect of itching, rusting, swelling in the skin and massive burning sensation. Citronella oil (Cymbopogon nardus) have a chemical content which are insecticidal among them is citronellal which can be used as a natural pediculosid. This research aims to formulate lotion preparations that are stable and effective as anti-fleas and increase the time of death of fleas compared to permethrin. The concentrations of citronella oil used for F1, F2 and F3 were 5%; 7.5%; and 10%. The three formulas were evaluated including organoleptic examination, homogeneity, pH, emulsion type, dispersibility, viscosity, skin irritation, cycling test, and anti-lice activity test. Data analysis used the Kruskal Wallis statistical test. Based on the results of the evaluation of the preparations, it was found that the organoleptic examination of the preparation of lotions FI, FII, FIII had a consistency of thick to liquid form, white to pale yellow, had a distinctive smell of citronella oil, FI test pH = 7.31-6.51, FII = 7 03-6,38 and FIII = 6,98-6,35, FI spread ability test = 6,15-7,75 cm, FII = 6,55-8,25 cm and FIII = 8,55-10,05 cm, emulsion type test FI, FII, FIII have emulsion type M / A, FI viscosity test = 2956-3107 cPs, FII = 2360-2677 cPs, FIII = 764-980 cPs, homogeneity test on FI, FII, FIII homogeneous, freeze and thaw test on FI, FII is stable while FIII is unstable, skin irritation test on FI, FII, FIII is not irritation, FI anti-flea activity test = 122-167 seconds, FII = 117-128 seconds, FIII = 69-90 seconds.

Abstract

Kenaikan jabatan merupakan suatu faktor yang sangat penting bagi perencanaan karir karyawan, dan juga menjadi dorongan untuk seseorang untuk maju menjadi lebih baik. Seringkali proses kenaikan jabatan dilakukan secara manual, atau secara objektif yang mengakibatkan kecemburuan atau kesenjangan sosial antar karyawan, dan dalam mengambil keputusan kenaikan jabatan banyak melibatkan aspek-aspek yang berupa himpunan samar (alamiah), sementara data hasil penilain masih berupa nilai pasti. Hal ini tentunya memakan banyak waktu untuk mengkonversi dari nilai pasti tersebut kedalam himpunan samar apabila dilakukan secara manual. Untuk itu dalam membatu mengambil kepututsan di PT Prioritas Outlet Bukittinggi dapat menggunakan Logika Fuzzy dengan Metode Tahani agar mendapatkan hasil yang akurat. Promotion is a very important factor for employee career planning, and is also an encouragement for someone to progress to become better. Often the process of promotion is carried out manually, or objectively, which results in jealousy or social inequality between employees, and in making decisions about promotion involves many aspects that are in the form of a vague (natural) set, while the assessment result data is still in the form of definite values. This of course takes a lot of time to convert the exact values ​​into a vague set if done manually. For this reason, to help make decisions at PT Prioritas Outlet Bukittinggi, you can use Fuzzy Logic with the Tahani Method to get accurate results.

Abstract

Based on Ratyanake's research (2018), it shows that blue light hitting the eyes for a long period of time can trigger photoreceptor (light-sensitive) cells to produce toxic molecules that are harmful to the eyes. Based on the Jhonson survey in Indonesia in 2019 in Raharjo (2019), there are 97% of Indonesian people who feel disturbed when they get excessive and blinding light in their eyes in their daily activities. In this study, researchers used secondary and primary data as research data, secondary data was taken from optical sales data and primary data was taken by giving questionnaires to consumers of Optik X mobile area, the sample used in this study amounted to 30 people, for data processing the author uses SPSS 25 software. The results of this study indicate that there is an influence between the blue cut lens and the response that has a positive and significant effect on the comfort of gadget users in the Optik X mobile area, this is based on a hypothesis test (partial t test) with the results of the t value of 6.254 > t table 2,051. This means that H1 is proven correct, so it can be concluded that there is an influence between the use of blue cut lenses on the comfort of gadget users in the Optical Melawai mobile area of West Jakarta.

Abstract

This study aims to determine the characteristics of tanned leather using alternative vegetable tanning agents from bark extracts and Acacia auriculiformis and Acacia mangium at pH 4 and 8. The research method uses the standard tanning method using salt preserved goat skin. Chemical analysis and physical testing of tanned leather refers to SNI-06-0463-1989-A and SNI 0234:2009. Based on the chemical analysis of tanned leather for both tanner extracts at pH 4, the tanned leather was produced imperfectly with low bound tannins and low wrinkle temperature. Tanned leather at pH 8 using A. auriculiformis and A. mangium extracts through single tanning has met the SNI standard.
