<![CDATA[Proses pemancangan seringkali mengalami kendala dalam mengantisipasi keberadaan rongga ataupun gua dalam tanah yang akan mempengaruhi kegagalan daya dukung friksi atau bahkan kegagalan daya dukung ujung pada tiang pancang. Komposisi batuan yang berada pada pondasi tiang bor dan tiang pancang yang memiliki karakteristik batuan gamping terumbu yang cenderung porous dan berongga perlu mendapat perhatian khusus. Penyelidikan dengan menggunakan geolistrik membantu proses identifikasi secara cepat untuk mengetahui kondisi tanah dan batuan yang berada pada lintasan-lintasan tertentu ada posisi pier dan abutmen yang ditengarai menembus lapisan tanah dan batuan berongga dan dikhawatirkan akan berada di lapisan yang berongga atau goa kapur. Pengujian geolistrik dilakukan dengan menggunakan 3 lintasan pengukuran yang masing-masing berada pada lajur centre line, sisi kiri dan sisi kanan grup tiang. Hasil pengukuran disandingkan dengan hasil pengeboran menunjukkan bahwa posisi rencana tiang pancang berdiri pada lapisan tanah dan batuan yang masif dengan komposisi batuan gamping terumbu berselang-seling dengan rekahan dan rongga, clayshell dan marmer atau batuan intrusi yang keras. Sementara rongga dengan diameter yang lebih besar dan terindikasi sebagai goa juga ditemukan pada beberapa tempat di sekitar rencana penempatan tiang bor/tiang pancang.]]>

<![CDATA[Abstrak Perkembangan peraturan konstruksi tidak lagi mengatur jarak gading. Sehingga para perancang kapal merencanakan jarak gading yang optimal dengan batasan resiko tekuk pada pelat menurut peraturan klasifikasi, momen batas struktur kapal harus sama dengan atau lebih besar dari 1.2 kali momen lentur vertikal (sagging dan hogging). Momen lentur vertikal dihitung dengan menggunakan formulasi yang telah diberikan oleh BKI. Penelitian ini bertujuan untuk mengetahui kekuatan batas pada struktur kapal ferry Ro-Ro yang membandingkan hasil dari dua metode yaitu Metode Smith dan NLFEA. Ro-Ro adalah kapal yang menangani muatannya dengan cara rolling it on and off di atas single or series ramps. Ramps yang dapat bekerja baik saat di kapal dan dermaga. Pada penelitian ini menunjukkan perbandingan nilai hasil dari metode NLFEA lebih besar daripada metode Smith. Hal ini dikarenakan metode NLFEA dapat menghitung redistribusi beban dan interaksi antara kegagalan lokal dan global secara kompleks sehingga keakuratan hasil perhitungan metode NLFEA lebih baik daripada metode Smith. Semakin jauh jarak gading maka semakin kecil beban batas agar pelat mengalami tekuk. Kata Kunci: Kapal Ro-Ro, Penampang Melintang, Jarak Gading, Tekuk, Kekuatan Batas Abstract The development of construction's regulation is no longer determining the distance of the frame. Hence, the designers make the optimal frame distance plan with the ultimate risk of bending on the plate. According to the classification rules, the structure's ultimate moment must be equal to or greater than 1.2 times vertical bending moment (sagging and hogging). This study aims to determine the ultimate strength on the structure of a Ro-Ro ferry which comparing two methods between the Smith and NLFEA Methods. Ro-Ro is a ship that handles its cargo by rolling it on and off over a single or ramp series. Ramps that can work well on board and dock. The use of ANSYS application that applied NLFEA method in this study shows the comparison of result value of NLFEA method is greater than Smith method. This is because the NLFEA method can calculate load redistribution and the interaction between local and global failures in a complex way so that the accuracy of the NLFEA method is better than the Smith method. The further the ivory distance the smaller the load limit for the plate to buckling.]]>

<![CDATA[Tourism objects in the district of Nabire relatively not developed much and has not been handled optimally due to lack of promotion. E-Tourism which is an electronic application for the tourism sector that can facilitate the user to visit a tourist site at a location. The currently available apps can not make real-time data changes regarding the position of the app's user coordinates to find out where to find the sights. This study aims to provide information to application users about the position of the location of the tour and the position of users who can change in real-time using firebase. This research uses experimental method, that is pinned firebase platform on E-Tourism so that application can utilize various real-time database feature in firebase. The system is tested by moving the user's position of the app to see changes in position data in real-time and will be shown on the application map. The next test by showing the location of tourism as well as the path traveled by the user to reach the sights. The results of this study show the position of the user that can change in real-time when the user to switch position without having to refresh the data manually (refresh). Applications can also display a list of tourist sites and the path taken to get to the tourist sites located in Nabire district.]]>

<![CDATA[Load scheduling is essential for optimizing power transmission on the system. The way to produce a stable electrical energy transmission system is to minimize transmission losses using between the moment of inertia and power on the generator. The generation noise is a description of the power losses on the transmission line generated when the power plant sends the load power. Transferring power from a high losses plant to a low losses plant. Rescheduling System can minimize transmission system losses. In this research, the scheduling result of this method is compared with the realization of scheduling of thermal generators from PT PLN (Persero) Sulselbar Central Disbursement and Control Center (P3B). This comparison aims to prove this method better than scheduling realized PLN, so that found also advantages and disadvantages method. After the research, this method produces a generation power that is close to stability, because the amount of power generated close to the power generation of PLN in fulfilling the same load demand remains with smaller transmission losses and cheaper fuel costs. The result of stable loading results in the efficiency of the electricity company so that it can reduce the operational cost of the generation and of course indirectly impact on the low cost of electricity production.]]>
