Spray Coating

Penelitian ini menggunakan metode penelitian kuantitatif. Penelitian ini dilakukan di PT. Maspion I Divisi  Maxim Departemen Produksi Spray Coating. Data dikumpulkan dengan menggunakan alat bantu kuesioner terhadap 70 karyawan yang diambil secara sample random sampling. Analisis ini menggunakan analisis regresi linier berganda, dengan uji instrumen uji validitas, uji reliabilitas, uji asumsi klasik, dan determinasi menggunakan aplikasi komputer program SPSS 16.0. Dari hasil uji parsial (uji t) untuk Hasil uji t untuk variabel keselamatan dan kesehatan kerja (X1) mendapatkan Nilai signifikan sebesar 0,006 < 0,05 dan nilai Thitung 2.841 > Ttabel 1.667 sehingga dapat disimpulkan bahwa H1 ditolak Ha diterima, Hasil uji t untuk variabel lingkungan kerja (X2) mendapatkan Nilai signifikan sebesar 0,023 < 0,05 dan nilai Thitung 2.335 > Ttabel 1.667 sehingga dapat disimpulkan bahwa H2 ditolak Ha diterima, Hasil uji t untuk variabel semangat kerja (X3) mendapatkan Nilai signifikan sebesar 0,016 < 0,05 dan nilai Thitung 2.477 > Ttabel 1.667, sehingga dapat disimpulkan bahwa H3 ditolak Ha diterima, Hasil uji t untuk variabel stres kerja (X4) mendapatkan Nilai signifikan sebesar 0,021 < 0,05 dan nilai Thitung 2.365 > Ttabel 1.667, sehingga dapat disimpulkan bahwa H4 ditolak Ha diterima, jadi dapat disimpulkan bahwa semua variabel dari keselamatan kerja, lingkungan kerja, semangat kerja, dan stres kerja berpengaruh secara parsial terhadap kinerja karyawan PT. Maspion I Divisi Maxim Departemen Produksi Spray Coating. Dari hasil uji simultan (uji f) perhitungan yang diperoleh nilai F hitung sebesar 11.438 dengan tingkat signifikasi 0,000 < 0,05. Dengan demikian keputusan yang diambil Ho ditolak dan Ha diterima. Hal ini berarti bahwa semua variabel bebas secara bersama-sama mampu memengaruhi variabel terikat secara signifikan. Dari koefisien determinasi menjelaskan bahwa variabel bebas mampu menjelaskan sebesar 41.3% dan sebesar 58.7% dijelaskan oleh variabel lain yang tidak diteliti dalam penelitian ini.Kata Kunci : Keselamatan dan Kesehatan Kerja, Lingkungan Kerja, Semangat Kerja, Stres Kerja, dan Kinerja Karyawan.

Allergic Effect

Background: Sargassum polycystum C. Agardh has potent antioxidant and anti-inflammatory properties. However, its anti-allergic effect has not yet been reported. In this study, we investigated the anti-allergic effects of sulfated polysaccharide of S. polycystum (SPSP) in Dinitrofluorobenzene (DNFB)- induced allergic contact dermatitis animal model. Methods: SPSP was extracted through hot water extraction method and was subjected to compositional analyses. For the allergic contact dermatitis (ACD) model, symptoms were induced by the topical application of 0.5% DNFB on the shaved ventral skin of mice. SPSP (500, 1000, and 2000 mg/kg) and Prednisolone were orally administered for seven days after sensitization. Elicitation was performed seven days later with 0.2% DNFB. After this, ear thickness was measured at baseline and 24 hours post elicitation using a dial thickness gauge. Serum of mice was obtained 24 hours post elicitation, and the level of IFNγ and TNF Results: SPSP afforded 33.6% carbohydrates, 23.7% sulfate, 7.5% protein, and 1.5% uronic acid contents. SPSP inhibited the ear swelling and cytokines (IFNγ and TNF Conclusion: These findings showed that the sulfated polysaccharide from S. polycytum is a potential natural source to treat Allergic Contact Dermatitis. The effect is attributed to polysaccharide-protein complex present in the extract, but further studies are needed to establish the exact mechanism of action of SPSP in the treatment of the disease.
