Abstract

Media salinity is a masking factor that plays an important role in controlling the process of shrimp molting and osmoregulation. Both of them are ecophysiological factors for shrimp life, so it is necessary to know the optimum level or range of media salinity for each phase of the molting phase changes in the stage and osmoregulation phase. This study was conducted to examine the molting frequency of adult L. vannamei which was ablated and cultivated at various levels of salinity. This research was carried out for 60 days. This study uses experimental laboratory methods with a systematic randomized design (RAS) with 4 treatments and 3 replications in each treatment. The treatments tested were salinity with S1 treatments (10 ppt, 289.20 mOsm / l postmolt H2O isosmotic), S2 (15 ppt, 432.80 mOsm / l H2O initial intermolt isosmotic), S3 (25 ± 1 ppt, 725, 15 mOsm / l H2O isosmotic final intermolt) and S4 (29 ± 1 ppt, 820.10 mOsm / l H2O isosmotic molt). Data were analyzed with ANOVA. Meanwhile, the difference in effect between treatments was obtained through Duncan's multiple area test. ANOVA results showed that various levels of isoosmotic media salinity at various molting phases had an influence (p <0.05) on molting frequency. The best value of molting frequency was in the S4 treatment (29 ± 1 ppt) (close to isoosmotic molt) 10 times. In the maintenance of L. vannamei which is affixed, it should pay attention to the needs of isoosmotic media, namely media with a salinity of 25 ± 1-29 ± 1 ppt (final intermolt isoosmotic range / premolt to molt). the difference in effect between treatments was obtained through Duncan's multiple region test. ANOVA results showed that various levels of isoosmotic media salinity at various molting phases had an influence (p <0.05) on molting frequency. The best value of molting frequency is in the treatment of S4 (29 ± 1 ppt) (close to isoosmotic molt) 10 times. In the maintenance of L. vannamei which is affixed, it is better to pay attention to the needs of isoosmotic media, ie media with a salinity of 25 ± 1-29 ± 1 ppt (final intermolt isoosmotic range / premolt to molt). the difference in effect between treatments was obtained through Duncan's multiple region test.

Abstract

The use of light wood combined with heavy wood can improve the quality of the combinationwood. Apart from being used as laminated beams, a combination of light wood and heavy wood can also be used as a laminated column given compressive loads. Based on SNI 7973-2013, the adhesive that was permitted on built up columns or laminated columns can be in the form of bolts and nails, so this study has also used adhesive nails and bolts. This study purpose to determine the compressive capacity of the laminated column which combines several types of wood. The specimens made were four variations of the laminate column. Furthermore, three layers of wood have been used on one laminated column with heavy wood types on the outermost layer. The results showed that all variations of the laminated column had a higher compressive capacity than the solid column. Keywords: compressive capacity, lamination column, light and heavy wood

Abstract

Project implementation is said to be optimal if good project management planning so that it can be done efficiently, qualified, safe, and economical. To produce an optimal project management is required with certain methods adjusted by the project. The purpose of this study is to determine the scheduling of project time to be done by using CPM network method (Critical Path Method) which will result in the length of time of completion of the project and determine the start and end time in each work. The first step is to conduct a field survey, collecting project data such as time schedule, and basic theory. After the data collection is considered enough, then the data is determined again with the method of CPM (Critical Path Method), followed by determining how much the cost to be incurred, and then made barchart and curve S. From the research results obtained, for project implementation can be completed with time work plan 282 days or 47 weeks. But with that time there are some critical work that will affect the duration, so special attention is required on the work. And costs incurred as much as Rp 223,363,901,783.98.Keywords : CPM (Critical Path Method), Duration of Work, Project Cost, Barchart, and Curve S

Abstract

PT. Cirebon Power Services is the first steam power plant (PLTU) in Indonesia that uses Supercritical Boiler technology. Combustion in a boiler using coal fuel produces hot gas which must be disposed of by utilizing a vacuum from the ID Fan and releasing it into the atmosphere. Gas Air Heater is a device that utilizes convection heat transfer from boiler exhaust heat to heat Primary Air and Secondary Air. The analysis was carried out by comparing the Gas Air Heater A and B through three parameters namely Air Leakage, X Ratio, and Efficiency. Data was collected from 31 December 2019 to 30 January 2020. The efficiency value of Gas Air Heater A was obtained 66% - 68% and Gas Air Heater B was 62% - 64%. The value of Air Leakage Gas Air Heater A is obtained 6% - 9% and Gas Air Heater B 10% - 12%. The value of X Ratio of Gas Air Heater A is 0.74 to 0.77, greater than Gas Air Heater B 0.68% to 0.71%.

Abstract

World Resources Institute data shows that there will be a fresh water crisis in 2040 including Indonesia. Responding to the above, many studies have been carried out using seawater, one of which is on concrete. Several studies have shown that seawater does not reduce the quality of concrete, but provides a corrosion effect on reinforcement.In this study, sea water concrete slabs have been made using bamboo as a reinforcement that will not corrode due to seawater. For concrete mix design refers to SNI SNI 03-2834-2000 and for slab flexural strength refers to 03-2847-2002. Slab specimens with sea water concrete that have been made consist of Slab concrete of steel reinforcement (SCS), Slab concrete of bamboo reinforcement V type notch (SCBV)  and Slab concrete of bamboo reinforcement  U type notch (SCBU).The result of the compressive strength of sea water concrete can reach the compressive strength of the plan. Tensile strength of bamboo reaches 223.5MPaand approaching the tensile strength of steel reinforcement. The maximum load of SCBV and SCBU were decrease than theoretical analysis of0.14% and 21.51% respectively. Otherwise, the maximum load of SCS greater than theoretical analysis with a difference of 14.67%. The flexural strength of the concrete slab was not affected by sea water as in compressive strength of cylinder.Keywords: Bamboo reinforcement slab, Flexural strength, Seawater concrete
