The danger of buckling and instability structures easily occurs on the steel beam structure, it will make the structure fails before it reaches the cross section ultimate capacity.In that case the strength of a beam is not only determined by cross-section ultimate capacity. The instability of the structure causes lateral torsional buckling eventhough there is no torque on the beam. There is one way to support the stability of the beam; by installing lateral support on its side. This research is intended to obtain information about flexural strength by comparing the theoretical results based on SNI 03-1729-2002 and (Indonesian National Standard Draft) RSNI 03-1729.1- 201x with the results of experimental testing and finite element analysis results (using the ABAQUS program). The flexural specimens which are studied are in the long-span with a length of 3.3 meters span test. The loading uses three-point load system. The results of the test show information that flexural strength for the long-span specimen from experimental test results has the smallest difference of 33.18% of the theoretical result. As for analysis with FEM also hasthe same difference of 33.18% with the experimental results. Failure that occurs for long-span specimen is due to lateral torsional buckling failures.

Konsumsi energi di Indonesia yang terus meningkat namun tidak berbanding lurus dengan ketersediaan sumber daya alam berupa minyak bumi dan batubara yang merupakan energi primer dalam pembangkitan listrik. Oleh karena itu, perlu dilakukan penghematan agar berimbang antara konsumsi dan persediaannya. Hal tersebut juga sesuai dengan Kebijakan Energi Nasional yangdikeluarkan pemerintah tentang penghematan energi yang salah satunya adalah penghematan bahan bakar. Proses start up unit Pembangkit Listrik Tenaga Uap (PLTU) Banten 3 Lontar dengan kapasitas 3 x 315 MW, menggunakan Big oil gun dengan bahan bakarnya yaitu HSD (High Speed Diesel) saja. Sejak 2014, Tiny oil gun muncul dengan konsep konsumsi bahan bakar yang jauh lebih hemat daripada Big oil gun . Start up dengan Tiny oil gun menggunakan sedikit solar + batubara. Start awal ini bertujuan agar tercapai temperatur dan tekanan di dalam ruang bakar (furnace). Perbedaan di antara keduanya jelas memiliki kelebihan serta kekurangan dari segi waktu, keandalan dan konsumsi bahan bakar. Penelitian ini menganalisa perbandingan penggunaan Big oil gun dan Tiny oil gun pada proses start up dan konsumsi bahan bakarnya yang kemudian dihubungkan dengan berapa besar biaya start up yang dikeluarkan setiap kali start up dilakukan selama penggunaan yang terus berjalan serta studi kelayakan investasi pada Tiny oil gun. Start up dengan Tiny oil gun berhasil menghemat konsumsi bahan bakar solar hingga 89,9% atau sebesar 54698 liter dan menghemat biaya Start up sebesar 61% atau sebesar Rp 263.836.213 per kali Start up serta hasil dari studi kelayakan investasi pada Tiny oil gun menyimpulkan investasi layak untuk diterima dan dijalankan.

The equivalence value and utilization by region in the focus of the Technology Strategy Analysis Photovoltaic solar power in Indonesia is a form of solar power energy potential optimization analysisbased on the results of the model output MARKAL by taking two cases: the base case (BASE CASE) and the case of investment costs vary PLTS (PVCOST). The base case is a case where all conditionsare taken based on the conditions from 2000 to 2016 when growth in electricity consumption is assumed to remain average, in 2030 Java is expected to require PLTS of 12.16 GW. But the use ofsolar power at 12.16 GW by-case basis and 46.65 GW in the case PVCOST in Java and 16.85 GW in the case PVCOST in Sumatra can be said to be irrational considering there are still local energysources that can be used like a mini/micro-hydro and geothermal has not been used optimally.

Corrosion is a common problem that often occurs in metals. Corrosion is the damage or degradation of metal due to the redox reaction between a metal with various substances in the environment that produce undesirable compounds. In the event of corrosion, the metal will experience oxidation while the air will experience reduction. Corrosion can be regarded as an electrochemical event between the metal and its environment. Simply, corrosion can occur if there are anodes, cathodes, electrolyte solutions, and metallic contacts between the cathode and the anode. In submarine pipelines, corrosion problems occur frequently for a corrosion-control measure. One of them is by using cathodic protection method using sacrificial anode system (sacrificial anode) and system impressed current (tilt current)

Tutorial method is a way of delivering learning materials that have been developed in the form of modules for students to learn independently. Students can consult about the problems and progress encountered periodically. Many limitations teacher, in choosing the right method of teaching cause lecturer difficult to realize the demands of the students in this teach. Acceleration we can see at universities around us, still very much a lecturer who uses teaching methods in a conventional way, such as lectures, notes, summarizes and etc. Research aims to determine the effectiveness of the use of the tutorial method of teaching in the department of mechanical engineering. This study uses research and development (Research and Development), the stage of preliminary studies carried out by applying a qualitative descriptive approach. The development phase is done by trial limited to the conventional model of teaching faculty by applying experimental methods (Single One Shot Case Study) After no improvement on the limited test then continued with a broader test of the experimental method in the form of groups (one group pretest-posttest). The latter is a tutorial teaching model validation methods eksprimen. The result of research shows that tutorial teaching methods more effective than the old teaching methods, both on the speed aspect of students' understanding of the lecture material, creativity, and student results.

Boiler is a heat exchanger that serves to evaporate boiler feed water to produce dry steam to drive the turbines in order to produce electricity. The fuels used in this study are dry wastes such as paper, plastic, and wood. The process of designing this boiler is carried out so that the use of diesel to generate steam on energy conversion practicum/experiment in STT-PLN is no longer needed. Instead, they can use dry waste as fuel to produce steam which later will drive the turbines. The residue of burning waste process in the form of ashes is approximately 0.053% of the weight or volume of dry waste before burnt. The calculation conducted on this works is to determine the design of evaporator and economizer pipe. The calculation is also adjusted to the generated steam needed in order to spin the turbines. The pressure produced from this boiler design should be 2.9 bar and for the amount of steam was 21 kg / hour. As a result, the calculation of evaporator surface area is 8,83 m2, result simulation HTRI 8.95m2 with 88 pipes and 1500 mm for each pipe, while the heated surface area for economizer is 0,46 m2 result simulation HTRI 0,45 m2 with 18 pipes and 400 mm long for each pipe.

One of the power plants in the labor system is hydropower, which is a power plant by utilizing water resources as its working fluid. In the operation of the hydropower requires high reliability sothat the energy production contuinitas to the load center or to the power system network can be more optimum. One of the components in the hydropower plant is penstock. Closed pipeline, whether it is laminar or turbulent, must have head losses. Head losses on penstock is a phenomenon of losses on the penstock so as to make the head value on the hydropower becomes reduced. At Penstock unit III PLTA Ir. H. Djuanda there are two phenomenon of head losses, namely: head losses major caused by friction penstock against water and minor head losses in the form of bend 900 with radius 4.375 m and 11.3 m from the axis penstock. Temperature changes affect the size of head losses, but they do not significantly affect penstock efficiency. At a temperature of 240C and a flow rate of 5m / s obtained a total head losses of 0606 m so as to make the potential of turbine inlet power down to 31,247 MW or 99.21%.
