Some inclined boreholes have to be drilled in directional wells, but the track of inclined borehole is impossible to be a ideal straight line, there are always some geometric defects such as bending, thus the drilling string in it is bound to have initial bending due to the constraints of borehole, hence the drilling string in inclined borehole is usually a curved compressed rod. Its buckling nature is quite different from straight compressed rod, it is necessary to analyze it specially. In this paper the buckling problem of drill string in inclined borehole with a concave curved geometric defect is studied by energy method, the computing formula of buckling load for it was obtained. And the influence of initial concave bending on buckling load was discussed. The research indicates that when drilling string in inclined well bore has a initial concave bending, the greater the degree of initial bending of drill string, the greater its buckling load.

“…[3], [4] menjelaskan bahwa da-lam penyelenggaraan angkutan umum tarif dapat mempengaruhi jumlah penumpang dan pendapatan sehingga perencanaan tarif merupakan faktor yang sangat penting. Perencanaan kebijakan tarif yang efektif dan terstruktur akan dapat terealisasi apabila mengkombinasikan antara kesejahter-aan dan keuntungan [4], [5]. Kebijakan tarif dapat dipandang sebagai kebijakan multisisi, di satu sisi dapat dipandang sebagai alat pengendali lalu lintas, di sisi yang lain dapat berarti alat untuk mendorong masyarakat mengunakan kendaraan umum dan mengurangi pengunaan kendaraan pribadi, dan sisi yang lainnya lagi dapat digunakan untuk mengarahkan perkem-bangan wilayah dan kota [6].…”

Pandemi Covid 19 memberikan dampak terhadap sector transportasi, dimana Pemerintah melakukan pembatasan terhadap pergerakan masyarakat. Hal tersebut berdampak terhadap melemahnya industri angkutan penumpang akibat dari menurunnya jumlah penumpang selama masa pandemi hingga post-pandemic. Penelitian ini bertujuan untuk mengetahui kinerja tarif angkutan perkotaan di Kota Cirebon, khususnya trayek D6 dengan pendekatan Biaya Operasi Kendaraan (BOK) berdasarkan data load factor actual di lapangan. Metode yang digunakan pada penelitian ini adalah survey primer yang meliputi survey headway serta survey naik turun penumpang. Data yang diperoleh kemudian dianalisis menggunakan pendekatan Biaya Operasi Kendaraan dalam menghitung tarif angkutan untuk mengetahui kesesuaian antara kondisi actual dengan biaya operasi yang harus dikeluarkan. Hasil penelitian menunjukan bahwa dengan kondisi actual (load factor rata-rata tertinggi adalah 45%) tarif yang berlaku saat ini sebesar Rp.6.000,-/pnp berada di bawah tarif berdasarkan biaya operasional kendaraan yang menghasilkan tarif sebesar Rp.8.707,-/pnp. Untuk menjamin kebertahanan operasional angkutan perkotaan di Kota Cirebon, maka perlu meningkatkan jumlah penumpang angkutan sesuai standar minimum load factor 70% atau menerapkan subsidi dari Pemerintah dalam penyelelenggaraan angkutan perkotaan.

“…In Groningen, the Netherlands, Cheung (2004) evaluated the effectiveness of the Tripperpas smart card and pointed out that technical reliability was relevant in winning user confidence and that check-in-check-out was a drawback for users. In Beijing, Chen et al (2005) evaluated an integrated fare initiative and concluded that reasonable pricing of PT was a challenge. Shon (1989) investigated PT fare integration in London and concluded that although there was some revenue lost to the service provider, it was beneficial to both users and society.…”
