Abstract

Many of the environmental pollution caused by the use of chemical pesticides. According to WHO, the pesticides used in the world as much as 3.5 million tons per year with the kind of high toxicity from developing countries such as Indonesia. The number of registered pesticides formula in Indonesia keeps increasing from year 1996 as much as 520 formula until 2015 as much 3,459 formula (Perveen,2011). The impact of pesticide contamination can be seen by measuring levels of the enzyme cholinesterase in the blood farmers. The purpose of the study to gauge the level of toxicity from pesticide usage by farmers by measuring levels of cholinesterase in the blood farmers and long usage of pesticides used by farmers. The benefits of this research to be able to provide information for farmers from the impact of the use of pesticides which do not use APD. This type of research is a descriptive experimental.This research was conducted on farmers in the area of Solok of West Sumatra with a simple random method of as many as 10 people. Data collection with the interview questionnaire and the wear measurement of levels of Cholinesterase in blood Cholinesterase Test Kit Livibond with AF267. The results showed that of the 10 samples examined 50% experiencing mild poisoning with levels of 62.5% Cholinesterase with a working period of 20 to 30 years, while the remaining >75% Cholinesterase levels are normal (default values are categorized decrease in AChE in Indonesia) and 10-15 year working period. Acute severe pesticide poisoning causes sufferers tounconscious, seizures, even death. chronic toxicity is more difficult to detect because it is not immediately felt, but in the long run can cause health problems.

Abstract

While the leaves of C. hystrix are commonly traded as cooking spices, their fruit cannot be consumed and is still a waste from the harvest. Scholars strive to take benefit of this fruit, especially after discovering that the C. hystrix fruit peel extract has better sunscreen and skin-lightening activity than their leaf and pulp extract. Therefore, this study aims to examine the sunscreen and skin-lightening activity of this fruit peel extract fraction, which was formulated as a face serum. The fractionation process began by separating ethanol extract and ethyl acetate extract of peel using column chromatography. The separation of extract fractions was based on Retardation factor (Rf) values. Extract fractions and peel extracts were then tested to observe the sunscreen and skin-lightening activity by calculating the Sun Protecting Factor (SPF), Protection grade UVA (PA), DPPH, and tyrosinase inhibition using the spectrophotometric method. Following that, face serum was formulated as gel and emulgel using chitosan and Carbopol-940 as gelling agents. The results showed that the best extract fraction was presented by fraction-6 of fruit peel ethanol extract (FEEP-6) with an SPF value of 26.790 ± 0.028 and fraction-1 of fruit peel ethyl acetate extract (FEAEP-1) with a PA value of 0.609 ± 0.021. Good extract fraction was also shown in fraction-5 of fruit peel ethanol extract (FEEP-5) with an IC50 value against DPPH and tyrosinase of 159.770 ug/mL and 214.156 ug/mL. FEEP-5 was used in the face serum dosage form with a concentration of 0.05%. All face serum dosages met the physical evaluation requirements. The best SPF and antioxidant values of face serum were presented by F4 of 26.505 ± 0.762 and 61.905 ± 0.571%, while the best tyrosinase inhibitor was formulated by F3 of 64.926 ± 0.090%. This study concludes that FEEP-5 and F4 are the best extract fractions and face serum formulas to be used as sunscreen and skin lighteners. In particular, FEEP-5 can be made into a face serum, such as emulgel, sunscreen, and skin lighteners.

Abstract

Antibiotic resistance to pathogenic bacteria has developed in a short period of time and is faster than has been thought. Therefore, it is necessary to find new antibiotic alternatives that are sourced from natural materials such as endophytic molds of dahlia tubers. This study was conducted to test the antibacterial activity of endophytic molds isolated from dahlia bulbs against Staphylococcus aureus and Stenotrophomonasmaltophilia strain W1-2. The results of the selection of antimicrobial activity of endophytic mold isolated from the dahlia tuber were fermented using the shaking method on Potato Dextrose Broth medium. The results of fermentation are tested for antibacterial activity using the disc diffusion method. Of the 10 isolated endophytic molds, two isolates with antibacterial activity were obtained, namely A-1 and A-7 isolates. The results of the antibacterial activity test of A-1 isolate against Staphylococcus aureus bacteria had the highest inhibition zone of 32.75 mm and Stenotrophomonasmaltophilia strain W1-2 had the highest inhibition zone of 19.25 mm. In A-7 isolate against Staphylococcus aureus bacteria had the highest inhibition zone of 29.5 mm and against Stenotrophomonasmaltophilia strain W1-2 had the highest inhibition zone of 15.25 mm. Based on the results of the antibacterial activity test carried out by the isolate, the isolate mold isolates with codes A-1 and A-7 have the highest antibacterial activity against Staphylococcus aureus and have a strong inhibitory power against Stenotrophomonasmaltophilia strain W1-2. The results showed that molds A-1 and A-7 had the potential to be antibacterial agents and GC-MS analysis of antibiotic compounds detected by hexanorlabdane. Molecular identification using the ITS gene observed that the A-1 mold isolate was 100% similar to the genomic2011f6MT558940.1 strain of Aspergillus Fumigatus

Abstract

Penerapan (SMKK) masih dianggap masih perlu dilaksanakan di Indonesia disebabkan masih tingginya angka kecelakaan kerja dibidang kontruksi. Hal ini disebabkan perilaku para pekerja yang sering mengabaikan Keselamatan dan Kesehatan Kerja (K3). Berdasarkan hasil observasi lapangan, masih dijumpai pekerja yang tangannya terluka karena tidak menggunakan sarung tangan, pekerja yang terpeleset dan tertusuk paku karena tidak menggunakan sepatu, dan penyedia jasa harus terlebih dahulu menyusun RKK karena dalam pengelolaan SMKK secara sistematis dan komprehensif wajib dilakukan sebagai upaya pencegahan kecelakaan kerja menjadi zero accident. Penelitian ini bertujuan untuk mengetahui dan mengevaluasi penerapan SMKK pada Proyek Pasar Raya Fase VII, apakah sudah sesuai dengan Peraturan menteri Pekerjaan Umum dan Perumahan Rakyat No. 10 Tahun 2021 tentang Pedoman SMKK, dan melihat kinerja para pekerja terhadap penerapan lima elemen SMKK dalam pembangunan Proyek Pembangunan Pasar Raya Fase VII sebagai upaya pencegahan kecelakaan kerja menjadi zero accident. Kinerja para pekerja dilihat dengan memberikan kuesioner terhadap 106 responden yang terdiri atas beberapa pimpinan terkait serta para pekerja proyek. Data yang didapatkan ditabulasikan dan diolah sesuai dengan ketentuan penetapan tingkat kekerapan berdasarkan SOP IBPRP yang dihubungkan dengan lima elemen SMKK yang harus dipenuhi. Berdasarkan data yang didapatkan dan setelah diolah dapat ditarik kesimpulan bahwa pekerjaan Proyek Pembangunan Pasar Raya Fase VII telah memenuhi kelima elemen SMKK dengan kategori hampir tidak pernah terjadi kecelakaan dengan rata-rata total sebesar 91,20%.
