Judul: Parameter Dinamika Populasi Ikan Cakalang (Katsuwonus pelamis Linnaeus, 1758) yang Didaratkan di PPS Cilacap, Provinsi Jawa Tengah.
Abstrak: Skipjack tuna (Katsuwonus pelamis) is a large pelagic fish that have important economic value in the Indian Ocean and also as a dominant fish landed in PPS Cilacap, Central Java. The aim of this research is to determine the population dynamics parameter of skipjack tuna in the Indian Ocean. This research was in December 2014 until March 2015. The data analysis conducted are sex ratios, gonad maturity, first lenght maturity, length frequency distribution and age, lenght and weight relationship, growth parameters, exploitation rate, and the surplus production model. The results shown growth of skipjack tuna move slow (K = 0,3). Lenght infinity (L∞) of skipjack tuna is 992,6303 mm, the exploitation rate is 0,93 and called as overexploited. Maximum sutainable yield (MSY) is about 3354,3 ton per year and optimum effort amount is 1700 trip per year. Management efforts to control fishing effort and restrictions of the fishing season.

Judul: Analisis Bioekonomi Sumber Daya Ikan Cakalang (Katsuwonus pelamis Linnaeus, 1758) di PPN Palabuhanratu, Provinsi Jawa Barat.
Abstrak: Bioeconomic analysis of skipjack tuna (Katsuwonus pelamis) was conducted to determine appropriate and sustainable fisheries resources management. This research was located in PPN Palabuhanratu, ProvinsiJawa Barat. In this research sampling was conducted four times during from December 2014 to March 2015. Data that was collected such as skipjack tuna’s length and weight, interview data, and statistical catch data of skipjack tuna. The aim of this research is to study skipjack tuna bioeconomic and sustainable yield. Exploitation rate with Ford Walford method is 0,6 per year. Surplus production model and bioconomic optimal effort of skipjack tuna is 317 trip per year with maximum sustainable yield 821 ton per year. Skipjack tuna fisheries resources utilization in this year can be estimated experience underfishing caused by some year before the utilization was overfishing. The appropriate policy that can be implied is limiting fish catch corresponding to Total Allowable Catch as big as 656 ton per year.

Judul: Synthesis of Molybdenum Trioxide (MoO3) by Electrochemical Method for Electrochromics Application
Abstrak: Molybdenum trioxide (MoO3) thin films have been deposited on glass substrates by electrochemical method using ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O244H2O). The films were deposited onto glass substrates as the control temperature at 25○C and annealing treatment at 350○C for 30 mins. The MoO3 thin films were investigated by UV-Vis, X-ray diffraction techniques (XRD), Scanning Electron Microscopy (SEM). The JCPDS card show that orthorhombic MoO3 (α- phase) has been formed. Molybdenum trioxide MoO3 formation was also confirmed by JCPDS card no. 35-0609. The SEM photographs revealed that the spherical and rod-like morphology and their grains size increased with increasing of heating temperatures. The measurement results show that the MoO3 thin film prepared at 350°C transmited about 80% of the visible spectrum. The effect of different heat treatments on surface morphology, thickness and optical properties of the films are discussed in this thesis.
