Abstract

Rancabali district in Bandung Regency Spatial Plan is included in the fourth hierarchical area chosen as a tourist center. Rancabali District has natural beauty, Sundanese traditional culture, and public education tours. The development of tourism in the Rancabali District has been apparent for five years between 2013 and 2018. This study aims to identify tourism developments based on the development of facilities for each tourist object, management of tourism objects, and visitor growth rate in the Rancabali District. The research method uses descriptive qualitative and interviews with tourism object managers. The development observed is the condition of tourist attractions for five years in the Rancabali District. Within five years, there were three new tourist attractions from 13 attractions in Rancabali District; there were developments in facilities in each tourist attraction, including 18 new inns, five new bathing pools, three cafes, and one outbound. The management of tourist objects in the Rancabali District varies the length of time they are managed. The longest is in the Situ Patenggang tourist attraction, which has rented the land area for 42 years. The growth rate of visitors illustrates tourism development in the Rancabali District; the most significant growth rate is in new tourist objects Glamping Lakeside which has an average growth of 47% over three years. The identification of tourism development in the Rancabali shows four forms of development, i.e., the existence of three new tourist objects, increasing the number of facilities in each tourist attraction, managing each different tourist attraction, and the number of visitor growth rates. Key Words : Rancabali District, tourism facilities, tourism management, tourism object

Abstract

High-quality turning is achieved through optimal cutting conditions. One of the variables affecting cutting conditions is surface roughness. The aim of this research is to examine the influence of feed rate and main cutting angle on the surface roughness of flat turning results on ST 37 steel material. The turning process was carried out with a cutting depth of 0.5 mm during the finishing process by varying the feed rate and main cutting angle. The feed rates used were 0.070 mm/rev, 0.281 mm/rev, and 0.450 mm/rev on ST 37 workpieces with a diameter of 24 mm and a length of 44 mm, which were turned down to a diameter of 23 mm along the same 44 mm length using a High Speed Steel (HSS) cutting tool. After the turning process, the surface roughness of the workpieces was measured using a Mitutoyo SJ-201P Surface Tester. The results of this study show that at main cutting angles of 80° and 90° and feed rates of 0.070 mm/rev, 0.281 mm/rev, and 0.450 mm/rev, the smallest surface roughness value achieved was Ra = 2.88 µm, corresponding to surface roughness grade N7, which occurred at a main cutting angle of 80° and a feed rate of 0.070 mm/rev. Meanwhile, the highest surface roughness value was Ra = 8.85 µm, corresponding to surface roughness grade N9, which occurred at a main cutting angle of 90° and a feed rate of 0.450 mm/rev.
