2. Madakaripura Waterfall (Enchanting with cliffs that surround it)





Madakaripura waterfall located in District Lumbang . This waterfall is still included in the Bromo Tengger Semeru National Park . Madakaripura waterfall -shaped niche with the surrounding hills , the entire field ridge tears . Niagara Mandakaripura can go from Probolinggo or from Malang . Madakaripura can be reached from Probolinggo by bus toward Tongas . 


3. Umbulan waterfall




Madakaripura arguably the most beautiful waterfalls in Probolinggo, even named as one of the most beautiful waterfalls in Indonesia. But who would have thought if in Probolinggo there are also waterfalls are no less beautiful than Madakaripura, even the location was not far from Madakaripura. The waterfall is named Niagara Umbulan, so local people call it. Administratively waterfall located in the village Umbulan Sukapura, Probolinggo. Umbulan location of the waterfall is not far to the District Office Sukapura, just half a kilometer.

4. Ranu Agung



Lake or can be called Ranu Supreme Court, is a lake formed from Lamongan volcano which is still active. Great Lakes has tourism potential is very beautiful, and worthy as a natural tourist destination with the atmosphere soothing view and surrounded by green trees. Grand Lake is located in the village of Ranu Court, district Tiris, Probolinggo district, to get to this area visitors can travel 40 Km Kota Probolinggo.


5. River Rafting Pekalen



Pekalen river is only 25 kilometers from Probolinggo. This river has a beautiful view, in the river Pekalen you can play rafting. This Pekalen river flows in three districts, namely Tiris, Maron and Ivory districts. Usually the location rafting rafting sports arena is extending as far as 29 km and is divided into three zones: the Upper Pekalen river as far as 12 km, Central Pekalen river as far as 7 km, and river Pekalen Down as far as 10 km. Every each zone has its own privileges. Down in Pekalen has 32 rapids were quite challenging, while Pekalen SMA has 10 waterfalls that drain adrenaline. Here too there are bat caves and wildlife along the way.

In contrast to the Tourism Mount Bromo, which has an extension BJBR Beejay Mangrove Resort was inaugurated in 2013 ago and became the center of attention of the tourists quickly. Towards this Mangrove tour is easy because it is situated not far from the square of the town of Probolinggo is precisely the north side of the square.

Pengaruh Feed Motion dan Kecepatan Pemotongan Terhadap Permukaan


A) Pengaruh Feed Motion (kecepatan pemakanan) Terhadap Kekasaran Permukaan Hasil Pembubutan
Feed motion memiliki peranan terhadap kekasaran permukaan dikarenakan feed motion adalah jarak yang ditempuh pahat perputaran. Artinya semakin besar feed motion semakin besar jarak yang disayat pahat setiap satu keliling benda kerja, sehingga antar puncak tiap sayatan semakin jauh yang menyebabkan kekasaran permukaan semakin besar. 
Feed motion berpengaruh terhadap kekasaran permukaan hasil pembubutan dapat dilihat pada gambar 5, dimana pada dimana pada feed motion 0,045 mm/rev menghasilkan nilai kekasaran permukaan rata-rata sebesar 5,47 mm, pada feed motion 0,09 mm/rev menghasilkan nilai kekasaran permukaan rata-rata sebesar 6,32 mm, pada feed motion 0,14 mm/rev menghasilkan nilai kekasaran permukaan rata-rata sebesar 6,87 mm, dan pada feed motion 0,18 mm/rev menghasilkan nilai kekasaran permukaan rata-rata sebesar 7,63 mm.


Gambar  Grafik hubungan antara feed motion dengan amplitudo dan kekasaran permukaan rata-rata hasil pembubutan

Kenaikan nilai kekasaran permukaan rata-rata disebabkan oleh meningkatnya variasi dari feed motion yang juga meningkat. Feed motion memiliki peranan terhadap kekasaran permukaan dikarenakan feed motion adalah jarak yang ditempuh pahat perputaran. Artinya semakin besar feed motion semakin besar jarak yang disayat pahat setiap satu keliling benda kerja, sehingga antar puncak tiap sayatan semakin jauh yang menyebabkan kekasaran permukaan semakin besar.
Hubungan antara feed motion dengan kekasaran permukaan dapat dilihat pada rumus :

Kenaikan nilai kekasaran permukaan rata-rata disebabkan oleh meningkatnya variasi dari feed motion yang juga meningkat. Feed motion memiliki peranan terhadap kekasaran permukaan dikarenakan feed motion adalah jarak yang ditempuh pahat perputaran. Artinya semakin besar feed motion semakin besar jarak yang disayat pahat setiap satu keliling benda kerja, sehingga antar puncak tiap sayatan semakin jauh yang menyebabkan kekasaran permukaan semakin besar.
Hubungan antara feed motion dengan kekasaran permukaan dapat dilihat pada rumus :

Keterangan :
Ra        = Harga kekasaran rata-rata  (mm)
f           = Feed motion (mm/rev)
re          = Tool nose radius (mm)
Dari rumus di atas dapat dilihat bahwa feed motion berbanding lurus dengan kekasaran rata-rata. Semakin besar feed motion maka kekasaran rata-rata yang dihasilkan juga akan semakin besar.




B) Pengaruh Kecepatan Pemotongan Terhadap Kekasaran Permukaan Hasil Pembubutan

Kecepatan pemotongan tidak berpengaruh terhadap kekasaran permukaan karena kecepatan potong adalah panjang pahat melakukan proses penyayatan per persatuan waktu . dalam hal ini diukur dengan satuan m/min. artinya kecepatan potong hanya berpengaruh pada panas yang timbul. Selama pahat potong masih bias menhan panas yan timbul mak maka hal tersebut tidak berpengaruh pada kekasaran permuakan.










Berdasarkan grafik (kanan) tidak pengaruh kecepatan pemotongan dengan terhadap kekasaran permukaan berupa garis mendatar yang menunjukkan bahwa tidak ada pengaruh kecepatan potong terhadap kekasaran permukaan.
