Persepsi Masyarakat Terhadap Kesetaraan Gender Pada Wanita dalam Olahraga

Penelitian ini dilatarbelakangi dari pengalaman pribadi yang mana lingkungan sekitar beranggapan bahwa wanita tidak boleh melakukan aktivitas berat karena akan membahayakan tubuhnya dan hal tersebut dikaitkan dengan mitos-mitos. Metode yang digunakan dalam penelitian ini adalah deskiptif Kualitatif dengan pendekatan studi kasus (CaseStudy). Subjek dan tempat penelitian yaitu pada masyarakat Kampung Cijerokaso Rw 10 sebanyak 4 orang. Pada penelitian ini, peneliti menggunakan instrument berupa wawancara dan observasi. Teknik pengolahan data yang digunakan adalah Kategorisasi Data, Penyajian Data, Verifikasi. Adapun hasil penelitian menunjukkan bahwa persepsi masyarakat mengarah kepada positif atau masyarakat setuju serta mendukung adanya kesetaraan pada wanita dalam olahraga. Disisi lain meskipun masyarakat mendukung adanya kesetaraan gender pada wanita tetapi masyarakat berharap adanya perbedaan antara laki-laki dan wanita misalnya dari segi waktu, intensitas, bobot berat dan lain sebagainya atau dapat dilakukan sesuai kebutuhan dan porsinya. Masalah mitos-mitos, masyarakat menerima adanya hal-hal tersebut tetapi bukan untuk meyakini karena bagaimana pun mitos-mitos tidak akan hilang walaupun zaman sudah semakin canggih karena negara Indonesia adalah negara yang kaya akan kearifan lokal yang berbeda-beda. penelitian ini terbatas dalam data yang cangkupanya besar, karena bahwasannya peneliti hanya meneliti lingkungan tingkat RW, perlu kiranya kedepan penelitian dapat dilakukan dengan data yang besar dan menggunakan metode lainnya seperti kuantitatif dan kominasi agar semakin dapat diketahui persepsi masyarakat terhadap kesetaraan gender pada wanita dalam olahrag

Calcium carbonate fouling on double-pipe heat exchanger with different heat exchanging surfaces

An experimental setup of double pipe heat exchanger fouling test rig was built to investigate the mineral scale deposition on different heat exchanger pipe surfaces. Progressive fouling deposition on different material surfaces under the similar solution conditions were observed and analyzed. Measurable data on the progressive build-up of scale deposits, deposition rate, as well as the composition and crystal morphology of the deposits were studied after each experimental run by analyzing the deposited scale on the test pipes. In this research the artificial calcium carbonate deposit on different material surfaces is considered as it is one of the major constituents of the most scales found in heat exchanging equipment. Fouling on different smooth test pipes were investigated in the centrally located larger concentric pipe heat exchanger. Uniform flow condition near the pipe surface was maintained by constant flow rate throughout the system. The calcium carbonate deposition rates on five different metal surfaces (Stainless steel 316, brass, copper, aluminium and carbon steel) were investigated. The results illustrated an upward trend for fouling rate with time on the tested specimens. The deposition on the surfaces showed a linear growth with the enhancement of thermal conductivity of the metals. However, deposition on carbon steel metal surfaces did not follow the typical linear trend of thermal conductivity over deposition as its surface was altered by corrosion effects. In addition, temperature, velocity, and concentration effects on fouling deposition were investigated on the SS316 metal surface. It is noted that the fouling deposition increases with the increase of temperature and concentration due to enhanced deposition potential whereas reduces due to the increase of velocity which enhances shear stress. © 2017 Elsevier B.V

EXPERIMENTAL INVESTIGATION OF THE TOOL-CHIP INTERFACE TMPERATURES ON UNCOATED CEMENTIDE CARBIDE CUTTING TOOLS

It is known that the temperature as the result of the heat developed during machining at the tool-chip interface has an influence on the tool life and workpiece surface guality and the methods for measuring this temperature are constantly under investigation. In this study, the measurement of tool-chip interface temperature using toolworkpiece termocouple method was investigated. The test were carried out on a AISI 1040 steel and the toolchip interface temperature variation was examined depending on the cutting speed and feed rate. The obtained groups show that cutting speed has more influence on the temperature than feedrate has

In this study, the effect of TiN coating by physical vapour deposition method on wear behaviour of austempered ductile iron was studied. For this purpose, austenitising at 900°C for 60 min and later austempering at 360 °C for 30 and 90 min was applied to the specimens. After heat treatment, the surfaces of these samples were coated TiN by PVD method. Wear tests were performed on pin-on-disc device under loads of 20 N, 40 N and 60 N, at linear sliding speed of 1m/sec and sliding distance of 1800 m. The experimental results show that pearlitic microstructure of ductile iron turned into ausferritic structure depending on heat treatment conditions. The wear of specimen was reduced 3-4 times by the effect of TiN coating
