O OPTIMALISASI PRODUKTIVITAS ALAT GALI MUAT TERHADAP PENGUPASAN OVERBURDEN DI PT XYZ
نویسندگان
چکیده
PT XYZ merupakan perusahaan yang bergerak di bidang pertambangan dan terletak Kabupaten Lahat Sumatwra Selatan. Target produktivitas fleet EXZ 5005 Mei 2021 sebesar 179,00 Bcm/jam. Dengan penambangan menggunakan alat gali muat excavator Caterpillar 345 GC. Pengupasan overburden dengan jenis material clay didapatkanlah pencapaian 173,97 Bcm/jam efisiensi kerja 72% cycle time 23,38 detik per siklus. Ketidaktercapaian ini dikarenakan faktor hambatan seperti terlambat datang kerja, terlalu lama istirahat, pulang lebih awal, engine problem, sliperry, hujan. Optimalisasi dilakukan cara memberikan toleransi keterlambatan 5 menit terhadap waktu hambat dapat dihindari sehingga meningkat 83% didapatkan peningkatan 200,55 Bcm/jam.

Analisis Keamanan Protokol Secure Socket Layer (SSL) Terhadap Proses Sniffing di Jaringan
Development of information technology, especially in the field of computer network allows the exchange of information faster and more complex and the data that is exchanged can vary. Security of data on communication in the network is a major thing. Secure socket layer (SSL) is the solution to the problem, but further research on the security of the SSL protocol transactions should be done to d...
متن کاملO,O′-Di-p-tolylpyrophosphoric bis(dimethylamide)
The title compound, C(18)H(26)N(2)O(5)P(2), was obtained accidently from the reaction between N,N-dimethyl-phospho-ramido-chloridic acid 4-methyl phenyl ester, NaNO(2) and 18-crown-6 in acetonitrile under reflux conditions. The asymmetric unit contains one half-mol-ecule, the complete mol-ecule being generated by crystallographic twofold symmetry, with the bridging O atom lying on the rotation ...

All the cyclo-hexane rings adopt chair conformations and the cyclo-pentane ring adopts a twisted envelo...
متن کاملXYZ Privacy
In this paper, we present the XYZ Privacy mechanism. XYZ Privacy maintains constant error from the ground truth while each data owner submits multiple contradictory responses, achieves scalable non-attributable (privatized) writes, and it protects the aggregate answer against malicious data owners attempts to corrupt (e.g., pollution attacks). We show an optimization of a square root reduction ...

In the title compound, {(C(10)H(11)N(3))[Zn(3)(C(8)H(4)O(4))(4)]·2H(2)O}(n), divalent Zn atoms are linked into trinuclear units featuring tetra-hedral, octa-hedral and distorted tetrahedral, octahedral and square-pyramidal coordination geometries. These trinuclear units are connected by isopthalate dianions into [Zn(3)(isophthalate)(4)](n) (2n-) anionic layers, which aggregate into the three-di...
