"ABSTRACTWarm-up is an essential part of preparation for rowing, especially in competitions. Respiratory muscle warm-up has been proposed to be the beneficial warm-up protocol for enhancing rowing performance. Therefore, the aim of this study is to determine the effect of inspiratory and expiratory muscle warm-up on rowing performance. The design of the study is a crossover study with controlled experiments. Fourteen youth rowers from the Rower and Canoeing Association of Thailand (six males, eight females) had to perform two warm-up protocols: specific rowing warm-up (SWU) and a combination of inspiratory and expiratory muscle warm-up with specific rowing warm-up (RWU+SWU). Afterwards, they had to perform a six minute all-out test. Mean power, distance, pre- and post-maximum inspiratory and expiratory muscle strength (MIP, MEP) of these results were compared. The results showed no significant differences in mean power (p=0.233) and distance (p=0.177) between SWU and RWU+SWU. Furthermore, pre-post MIP and MEP were not different in both warm-up protocols. However, mean power and distance in male rowers tend to increase under the RWU+SWU protocol, but both of parameters result in females conversely. In conclusion, the effect of RWU+SWU on rowing performance is not different from SWU, but if gender is considered, male and female rowers will react to the RWU+SWU protocol differently. Hence, this should be further investigated with a larger number of participants."

"Skripsi ini bertujuan untuk melihat pengaruh efek kekakuan struktur terhadap perbedaan penurunan yang terjadi. Idealnya, perhitungan penurunan pondasi harus memperhitungkan antara kekuatan tanah dan parameter struktur atasnya. Pembahasan utama skripsi ini adalah untuk memasukkan parameter struktur atas ke dalam analisis dan melihat pengaruhnya terhadap penurunan pondasi. Perubahan luas bangunan dan jumlah lantai dilakukan untuk menghasilkan pola penurunan yang terjadi pada pondasi. Respon yang diamati adalah hasil penurunan pondasi dan differential settlement. Hasil akhir dari penelitian mengenai pengaruh efek kekakuan struktur struktur pada differential settlement pondasi adalah bentuk persamaan yang menunjukkan hubungan antara faktor kekakuan struktur dengan tebal pondasi.

This thesis evaluates the effect of structural stiffness on the differential settlement of raft foundation. Ideally, a analysis settlement of raft foundation should consider both the stiffness of foundation and structure. The main objective of this thesis is to include structural parameters into the analysis and to identify the effect on foundation settlement. Some structural variations specifically on building area and number of floors were considered to represent behavior of the foundation. The primary observed effects is the foundation settlement and differential settlement. The outcome of the evaluation is an equation that shows the relationship between the structure- raft parameters and the raft thickness."

"Menyadari luasnya kegunaan timah untuk kebutuhan industri maupun kebutuhan sehari-hari, maka dapat dipastikan angka permintaan timah terhadap timah akan terus meningkat setiap tahunnya. Namun di sisi lain, jumlah cadangan bijih timah di dunia justru terus mengalami penurunan. Salah satu cara mengatasi situasi ini adalah dengan mengolah kembali produk terak secara efektif dan efisien sehingga produk yang tadinya tidak memiliki nilai ekonomis menjadi berguna dan memiliki nilai tambah sebagai umpan tambahan dalam proses peleburan. Hal tersebut merupakan fokus utama dari penelitian ini.Penelitan ini bertujuan untuk mencari tahu temperatur roasting optimum agar diperoleh hasil yield recovery maksimal yang ditandai dengan besarnya nilai % recovery. Metode yang dilakukan adalah dengan mencampurkan sampel terak II dengan KOH(s) , lalu memanggangnya dalam muffle furnace untuk selanjutnya di-leaching menggunakan air hangat. Pengujian karakterisasi sampel yang dilakukan adalah X-RD, STA, dan AAS. Hasil dari pengujian menyimpulkan bahwa temperatur roasting optimum dicapai pada 650OC dengan nilai % recovery 10,39 %.

Realizing how wide the use of tin for either the industrial or daily life needs are, it can be ascertained that the demand of tin will be increasing every single year. On the other side, the amount of tin ore’s stockpiles are on the contrary decreasing. One of many ways to solve this problem is by redressing slags effectively and efficiently, so that, the product which had no economic value turns to be something valuable and useful as the addition decoy for smelting process. It is the main focus on this research.

The aim of this researh is to find out the optimum of roasting temperature in order to obtain the maximum yield recovery process which is marked by the number of % recovery. The method used on this research is by mixing the slag with KOH(s), then roasting them in muffle furnace, and leaching by warm water as the last step. This research used some characteristic examinations which are X- RD, STA, and AAS. It concludes the optimum of roasting temperature is reached at 650oC with 10,39 % recovery."
