The study finds that youth employment in Jordan is influenced by gender, educational level, geographical location, and marital status. According to the youths covered by this study, male youth stand a better chance of being employed than the female counterpart. Therefore, special attention must be paid to integrating the youth and particularly females better into the labor market for increasing the prospect of their employment. Practical Implication: The results can be used to mitigate the problems of youth unemployment, especially female youth unemployment, in Jordan and other Arab countries. Policymakers must focus on certain constraints, such as mobility and cultural factors, as roadblocks that may cause relatively higher youth female unemployment. Originality/Value: This is one of the latest attempts to identify, investigate, and analyze the causes of youth unemployment in Jordan. The study adds to scholarly debate on youth unemployment's main determinants by giving evidence from a developing country. However, this study unveils a unique feature of youth unemployment in Jordan; this study will bridge the literature gap, especially for Jordan, and help improve overall youth unemployment.

Tujuan dari penelitian ini adalah untuk menguji pengaruh good corporate governance terhadap kinerja keuangan. Populasi pada penelitian ini adalah seluruh perusahaan Badan Usaha Milik Negara sektor keuangan yang terdaftar di Kementerian Badan Usaha Milik Negara Republik Indonesia periode 2017-2019 yakni sebanyak 19 perusahaan. Pemilihan sampel dilakukan dengan menggunakan metode purposive sampling dan didapatkan jumlah sampel sebanyak 10 perusahaan. Teknik analisis data yang digunakan untuk menguji hipotesis adalah analisis regresi berganda dengan menggunakan software SPSS 24. Pada penelitian ini menggunakan tiga proksi untuk mengukur good corporate governance yaitu dengan menggunakan ukuran dewan direksi, proporsi dewan komisaris independen, dan ukuran komite audit serta kinerja keuangan diukur dengan menggunakan proksi return on equity. Hasil dari penelitian ini menunjukkan bahwa variabel ukuran dewan direksi berpengaruh negatif signifikan terhadap kinerja keuangan, proporsi dewan komisaris independen tidak berpengaruh signifikan terhadap kinerja keuangan, dan ukuran komite audit tidak berpengaruh signifikan terhadap kinerja keuangan.

The reduced production of fossil energy, especially petroleum, has encouraged researchers to continuously increase the role of new and renewable energy as part of energy security and independence. A Tesla turbine is a device that can be used to recover wasted energy from exhaust gases, thereby increasing the overall energy use. The purpose of this study was to assess the performance of a Tesla turbine using various parameters such as engine speed, the gap between the disks, the diameter of the disks, and the number of disks. In this study, the performance of a Tesla turbine was simulated using computational fluid dynamics (CFD). The reference dimensions of this Tesla turbine are made with a slit diameter of 44 mm, a hole diameter of 10 mm, disc diameter of 140 mm, a disc width of 1.5 mm, a disc gap of 35 mm, a disc gap width of 4 mm, and a shaft length of 50 mm. The results of this study were in the form of torque and pressure drop values. In the variation of engine speed, the highest torque was at 1800 rpm with a torque value of 0.422 Nm, and the highest pressure drop was at 1800 rpm with a pressure drop value of 79161.5 Pa. In the disk gap variation, the highest torque is at a 7 mm disk gap with a torque value of 0.54 Nm and the highest pressure drop is at a 4 mm disk gap with a pressure drop value of 79161.5 Pa. In the variation of disk diameter, the highest torque was found on the disk with a diameter of 180 mm and a torque value of 0.831 Nm, and the highest pressure drop was on a disk with a diameter of 180 mm and a pressure drop value of 86753.5 Pa. In the variation of the number of disks, the highest torque was found at eight disks with a torque value of 0.765 Nm, and the highest pressure drop was found at eight disks with a pressure drop value of 82031.3 Pa. After performing this simulation, it can be concluded that at variations in engine speed, the higher the engine speed, the higher the value obtained and the variations in the disk gap, disk diameter, and number of disks. There are several values of torque that increase and decrease because the input value given cannot always increase the torque value in these variations.

Comparison of Antibacterial Activities of Agarwood (Gyrinops versteegii) Resin and Leaf Crude ExtractThis research aim is to compare antibacterial activities of leaves extract and resin extract of Gyrinops versteegii with different extraction solvent and concentration. Leaves and resin had been prepared by drying and grinding then were extracted by maceration method. Factorial experiment design was used for extract application to Staphylococcus aureus ATCC25923. First factor was extract ingredient, second factor was extraction solvent, third factor was extract concentration. Inhibition zone as main parameter for antibacterial assay were analysed by ANOVA, HSD test and standard error. The inhibition zone of resin was higher than inhibition zone of leaves. The extraction solvent and extract concentration were not significantly resulted in different inhibition zone diameter. However, there were unique interaction between extraction solvent and extraction concentration that affected inhibition zone diameter. It could be concluded that the inhibition zone of resin was higher than that of leaves while no significant result from extraction solvent and extract concentration factorsKeywords: antibacterial, agarwood, extract, leaves, resin ABSTRAKPenelitian ini bertujuan untuk membandingkan aktivitas antibakteri daun gaharu dan resin gaharu G. versteegii menggunakan beberapa pelarut pengekstrak dan konsentrasi ekstrak yang berbeda. Bahan daun dan resin gaharu dikeringkan dan dicacah, kemudian diekstrak menggunakan metode maserasi. Uji aplikasi ekstrak pada Staphylococcus aureus ATCC25923 dilakukan menggunakan rancangan faktorial, yaitu faktor pertama bahan ekstrak (resin, daun), faktor kedua pelarut pengekstrak (etanol, metanol), dan faktor ketiga konsentrasi ekstrak (0,25; 0,5; dan 1 g mL–1). Data zona hambat terhadap bakteri uji dianalisis menggunakan ANOVA, BNJ dan standard error. Rerata zona hambat ekstrak daun gaharu (7 mm) lebih besar secara signifikan dibandingkan dengan rerata zona hambat ekstrak resin (6,5 mm). Faktor pelarut pengekstrak dan konsentrasi ekstrak tidak berpengaruh signifikan terhadap zona hambat. Pelarut pengekstrak dan konsentrasi ekstrak memberikan pengaruh interaksi berbeda-beda terhadap zona hambat. Dapat disimpulkan bahwa bahan ekstrak daun gaharu memiliki aktivitas antibakteri lebih bagus dibandingkan dengan ekstrak resin gaharu dengan konsentrasi ekstrak efisien sebesar 0,25 g mL–1.
