Abstract

Introduction: This research presents the relationship between the schools which implemented full day school and which did not apply the full day school to the level of stress students in junior high schools. This was influenced by the existence of regional autonomy as part of government policy and orientation toward quality education institutions.Methods: This research used a quantitative correlational approach to obtain the significance of the relationship between the variables examined.  The sampling technique used  purposive sampling, with samples of 37 students for a group of cases and 37 students to control groups. Data analysis was conducted using the Kolmogorov Smirnov test.Results: The results showed that in the case group there were 83.78 experiencing mild stress and 16.22 experiencing moderate stress, while in the control group there were 89.19 experiencing mild stress, and 10.81 experiencing moderate stress with P- value 0.000 (<0.05).Conclusion: The conclusion of this study is that more moderate stress levels are found in students who apply the Full Day School System in Junior High School.

Abstract

The purpose of this study wasto determine the marketing strategy, the effectiveness of the marketing strategy, the obstacles in carrying out the marketing strategy, and how to overcome the obstacles in carrying out the marketing strategy of health services during the JKN (National Health Insurance) era at the hospital. Lung Surabaya. This study uses a qualitative approach and the researcher as the key instrument. This technique of determining key informants is carried out before or when conducting field research. The technique used before the field research is the judgment of the researcher. Meanwhile, the technique of determining key informants during field research is snowball or snowball technique. The judgment technique is carried out using certain criteria that have been previously determined by the researcher in this study, namely the director, then using the snowballing method totaling 5 key informants. The validity of the data using the triangulation method. Analysis of the data from this study using data reduction, data collection, data display, conclusions

Abstract

ABSTRAK Industri tahu menghasilkan air limbah pekat atau whey (dadih), yang memiliki pH rendah dan bahan organik yang tinggi, sehingga dapat menyebabkan pencemaran lingkungan jika tidak diolah dengan baik. Di sisi lain, salah satu kandungan limbah tahu pekat yaitu protein dapat dimanfaatkan kembali untuk mengurangi potensi pencemaran lingkungan dan diolah lebih lanjut menjadi produk yang bernilai ekonomis. Penelitian ini bertujuan untuk mendapatkan data awal untuk menilai kelayakan penggunaan metode fraksinasi busa untuk pemulihan protein dari limbah tahu pekat. Limbah tahu pekat dalam penelitian kami memiliki konsentrasi protein awal 3.115 mg/l. Percobaan dilakukan dengan menggunakan reaktor fraksinasi busa berbentuk kolom dalam mode semi-curah. Kombinasi tiga laju alir udara (10, 30, dan 60 l/jam) dan tiga konsentrasi limbah tahu pekat (10, 50, dan 100%) diuji. Hasil percobaan menunjukkan bahwa konsentrasi protein awal mempengaruhi pemulihan protein, sehingga diperlukan konsentrasi protein awal sekitar 3.000 mg/l. Rasio pengayaan tertinggi 1,0 ± 0,5, setara dengan pemulihan protein 6 ± 4%, dicapai pada laju alir 10 l/jam dan konsentrasi limbah tahu pekat 100%. Peningkatan laju alir hingga 30 l/jam tidak mengubah rasio pengayaan (0,9 ± 0,2), tetapi meningkatkan pemulihan protein hingga 71 ± 14%. Penelitian lebih lanjut diperlukan untuk parameter-parameter lain seperti konsentrasi protein awal, komposisi limbah tahu pekat, laju aliran udara, ukuran gelembung, holdup cairan, dan desain reaktor. ABSTRACT The tofu industry generates highly-polluted wastewater called whey, which has a low pH and high organic matter, and therefore can cause environmental pollution when not treated properly. On the other hand, one of the whey constituents namely protein can be recovered from the wastewater to reduce its environmental potency and to be further processed as a product that has an economic value. This study aimed to obtain preliminary data to assess the feasibility of using the foam fractionation method for the recovery of protein from tofu whey wastewater. Tofu whey in our study had an initial protein concentration of 3115 mg.L-1. The experiment was performed using a column foam fractionation reactor in a semi-batch mode. Combinations of three air flow rates (10, 30, and 60 L.h-1) and three tofu whey concentrations (10, 50, and 100%) were tested. Our results show that initial protein concentration influenced protein recovery, with a protein concentration of approximately 3000 mg.L-1 required. The highest enrichment ratio of 1.0 ± 0.5, which corresponded to 6 ± 4% protein recovery, was achieved at 10 L.h-1 flow rate and 100% whey concentration. Increasing the flow rate to 30 L.h-1 did not change the enrichment ratio (0.9 ± 0.2), but increased the protein recovery to 71 ± 14%. Further investigation is needed for parameters such as initial protein concentration, whey composition, air flow rate, bubble size, holdup time, and reactor design.
