“…Data yang akan diperoleh setelah sampel krim pemutih wajah melalui proses eksperimen laboratorium, dan kandungan kadar hidrokuinon akan diidentifikasi lalu ditentukan dengan spektrofotometri UV-Vis. Data yang diperoleh secara spektrofotometri menggunakan spektrofotometer UV-Vis akan menampilkan hasil berdasarkan analisis kurva kalibrasi dan persamaan regresi y = a + bx Absorbansi yang dihasilkan masih memasuki rentang absorbansi yang baik yaitu jika memasuki rentang 0,2-0,8 karena pada rentang tersebut hukum Lambert-Beer berlaku dan tingkat kesalahan pembacaan oleh alat adalah yang terkecil (Nofita et al, 2016). Jika nilai absorbansinya yang dihasilkan kurang dari 0,2 maka konsentrasi pembuatan baku seri perlu ditingkatkan.…”

Whitening cream is a cosmetic product containing organic chemicals or other substances which are used to whiten the face or remove black spots on the skin. Whitening cream has many benefits for sufferers of skin disorders, namely being able to whiten and remove black marks. Meanwhile, the concept of beauty circulating in society is having white skin. This stigma makes people, especially teenagers, justify any means to get white skin. One way to beautify your skin is to use skin whitening and lightening products. The aim of this research was to determine hydroquinone levels in whitening cream in X City using UV–vis spectrophotometry. The method used in this research is quantitative using the UV–vis spectrophotometric method. The research results showed that all of the 15 samples tested were positive for containing hydroquinone with the highest percentage of hydroquinone found in S1, S5, and S10 with a percentage of 0.0581%; 0.062%; and 0.0501%. Meanwhile, samples with low percentages were in S4, S6, S7, and S12 with a percentage gain of 0.011%; 0.0134; 0.0103%; and 0.0105%. It can be concluded that the hydroquinone levels of the 15 whitening cream samples do not meet the requirements permitted by BPOM No. 23 of 2019, namely 0%.

“…Rentang nilai absorbansi pada sampel ini berada diantara 0,5 -0,8. Absorbansi maksimum pada sampel jika menggunakan spektrofotometer uv-vis yang baik yaitu berkisar diantara rentang 0,2 -0,8 karena pada rentang tersebut hukum lambert-beer berlaku dan tingkat kesalahan instrumen paling rendah (Nofita, et, al, 2016).…”

Air pollution from toxic substances is one of the world's health problems and causes environmental damage. Transportation contributes to the emission process that causes air pollution from motor vehicle exhaust gases. One of them is carbon monoxide which is a toxic, invisible, colorless, odorless, and non-irritating compound that can be toxic to humans in high concentrations. Carboxyhemoglobin (COHb) is formed when carbon monoxide and oxygen enter the body and compete to bind to hemoglobin. The purpose of this study was to determine the level of carboxyhemoglobin in traffic officers of Tangerang City transportation department. The method used in this research is Hinsberg-lang and the sample used is blood. The results showed that carboxyhemoglobin levels in the blood of traffic officers of the Tangerang City transportation department as many as 18 respondents (100%) were still within normal limits, namely with a range of levels of 0.061 - 0.064. Carboxyhemoglobin levels in traffic officers are below the COHb threshold value according to the Regulation of the Minister of Health of the Republic of Indonesia Number 70 of 2016 concerning Industrial Work Environment Health Standards and Requirements which is 3.5% of Hb.

“…The most visible antibiotic residues were in chickens because antibiotics were used as a treatment method, infection in chickens without controlling the dose and use of antibiotics, and antibiotics as feed additives in feed. Research showed excessive doses of antibiotic residues in chicken farms and markets were easily found [8,11,12]. The common reasons for tetracycline usage were easy to use and cheap.…”

Antibiotic usage in chickens can help to prevent disease and increase their growth rate. However, many farmers ignore the doses and the withdrawal time of antibiotics usage for chickens so that it can cause antibiotic residue in chicken meat. This antibiotic residue can cause health problems, so it is necessary to take action to reduce or find other alternatives for antibiotic usage in chickens. Therefore, our research objective was to summarize the records of tetracycline residue in broiler chickens. In addition, this research also identifies the effect of Lactobacillus usage as an antibiotic replacement. This research was a systematic review. The systematic review intended to synthesize in detail the information about natural ingredients for antibiotic substitutes and their effect on chicken’s growth from Google scholar, Science Direct, and Pub Med with the keywords “Tetracycline effect,” “Probiotics antibiotic,” “Lactobacillus antibiotics,” “Chicken antibiotics,” “Tetracycline residue” and “Chicken growth.” The results obtained from this systematic literature review were that the residual levels found in chicken samples from Indonesia and Egypt ranged from 0.7 to 61.05 mg/kg. In addition, the addition of Lactobacillus had a positive effect on the weight of chickens, namely the addition of 23.3 to 1421.67 g. This study concluded that the residual levels of tetracycline in chickens exceed the safe consumption limits set by the Standard Nasional Indonesia (SNI). The usage of Lactobacillus was common as feed additives.
