Length-Weight Relation and Growth of Mangrove Crab
This study aims to determine the relation of length-weight and growth of mangrove crabs (Scylla serrata) in the Mootilango Village, Duhiadaa Sub-district, Pohuwato Regency. This research was conducted by observation for ± 6 months starting from September 2015 until February 2016. The sampling area covers all of Duhiadaa Sub-district mangrove forest with random sampling method. The result of the research shows that the relationship between carapace length and weight of mangrove crab (Scylla serrata) has the equation W = 6,026L2,444 with correlation (R2) = 0,850. Crab population consist of three age group (L1 = 61,66666667cm, L2 = 17,81981982, and L3 = 0,176691729 cm). While the maximum carapace length (Lâ) reach 17.204 cm with a growth rate coefficient of 0.2133 per year.

Pengaruh Disiplin Kerja, Pelatihan Kerja Dan Motivasi Terhadap Kinerja Karyawan
This Study aims to see relationship between work discipline, job training, and motivation towards employee performance at PT. Karya Indah Multiguna. The data used in this study are primary data obtained from 86 respondents who have filled out a questionnaire. This study uses multiple linear regression analysis, hypothesis testing with the t-test and f-test methodes and to see the determinant coefficien. The test result of multiple linear regreession analysis : X1 sig value (0,001<0,05), then HA is accepted which means that there is a significant effec of work discipline on employee performance, X2 (0,001<0,05) then HA is accpeted which means there is a significant effect on job traning performance, and X3(0,000<0,05) then HA is accepted which means that there is a significant effect of motivation on performance. The results of the research simultaneosly show that f count > f table with results (168,842>2,715) so simultaneously work discipline, job training and motivation have a simultaneous effec on perfomance

Early marriage or marriage at a young age is very prevalent among adolescents, where the occurrence of marriage is due to various factors of low access to education for children, quality of health services from reproduction, especially for girls who are lacking, there is no opportunity in the economic field , the existence of free association and also because of poverty, besides that marriage at this young age has a negative impact which can cause divorce, domestic violence, severe depression, the emergence of child labor, economic hardship and hampered education. Early marriage is a violation of children's rights, especially the right to live and grow and develop. This service activity provides an understanding of the impact of early marriage. Meanwhile, the aim is that students and students can understand the efforts to prevent early marriage in the aspects of marriage and child protection

Anesthetic Considerations in a Patient with Amiodarone-Induced Thyrotoxicosis
Amiodarone-induced thryrotoxicosis (AIT) is a rare but serious complication of amiodarone use, especially in patients with severe cardiac disease. We present a patient who developed AIT, following administration of amiodarone for life-threatening ventricular arrhythmias. We discuss the medical management of AIT and anesthetic considerations for management of patients with thyrotoxicosis and severe cardiac disease who require surgery including thyroidectomy
Modeling and simulation of permanent on-orbit servicing infrastructures dedicated to modularized earth-orbiting platforms
This research aims to quantify the responsiveness and cost-effectiveness of permanent on-orbit servicing (OOS) infrastructures providing services to multiple serviceable platforms in coplanar medium Earth orbit (MEO) and/or geostationary orbit (GEO). The customer satellites are assumed to be made of elementary units (EUs). EUs are small standardized structural units capable of aggregating with each other and gathering the key functions of a typical satellite within the size of a 6U cubesat. Two OOS infrastructures are modeled in this research. The first one, called âWithout depotâ (WoD), includes a launch vehicle and a robotic servicer. The second infrastructure, called âWith Depotâ (WD), includes a launch vehicle, a robotic servicer and an orbital depot of EUs. This research is divided in two parts. The first part quickly developed a Simulink-based event-driven simulation framework to compare the responsiveness of WoD and WD, and provide some insight into their respective cost-effectiveness. The metrics used to quantify responsiveness for this first study are the service completion rate and the average waiting time before an EU is replaced over a 10-year period of operation. It is shown that WD is more responsive thanWoD but is also likely to be more expensive to run. Based on this observation, the second part of this research developed a Python-based event-driven simulation framework capable of capturing a much larger trade space of the WD infrastructure than the Simulink framework does. The Python framework considers more accurate models and includes much more OOS design features, such as the number of servicers, more efficient service dispatch strategies and new space trajectories. For this second study, responsiveness is measured via the average working state of the population of customer satellites, which captures how well the satellites work based on three different failure severities and the number of failures. Cost-effectiveness is measured thanks to the average mass sent to orbit per year required to efficiently run the OOS infrastructures. It is first shown that there exist designs based on propellant optimal trajectories yielding similar levels of responsiveness as designs using Lambert-trajectory-based propellant-time-traded trajectories but at much lower costs. The second conclusion is that finding responsive and cost-effective OOS designs is not intuitive. This has to be done through an exhaustive exploration of the trade space of OOS, given the high number of design variables. This research si believed to be a critical milestone in the design of a responsive integrated space infrastructure dedicated to the development and prosperity of a new GEO/MEO economy
Multi-Fidelity Space Mission Planning and Infrastructure Design Framework for Space Resource Logistics
To build a sustainable and affordable space transportation system for human
space exploration, the design and deployment of space infrastructures are
critical; one attractive and promising infrastructure system is the in-situ
resource utilization (ISRU) system. The design analysis and trade studies for
ISRU systems require the consideration of not only the design of the ISRU plant
itself but also other infrastructure systems (e.g., storage, power) and various
ISRU architecture options (e.g., resource, location, technology). This paper
proposes a system-level space infrastructure and its logistics design
optimization framework to perform architecture trade studies. A new space
infrastructure logistics optimization problem formulation is proposed that
considers infrastructure subsystems' internal interactions and their external
synergistic effects with space logistics simultaneously. Since the full-size
version of this proposed problem formulation can be computationally
prohibitive, a new multi-fidelity optimization formulation is developed by
varying the granularity of the commodity type definition over the network
graph; this multi-fidelity formulation can find an approximation solution to
the full-size problem computationally efficiently with little sacrifice in the
solution quality. The proposed problem formulation and method are applied to a
multi-mission lunar exploration campaign to demonstrate their values.Comment: 34 pages, 3 figures, presented at the AIAA Propulsion and Energy

Objectives of the research are to examine and analyze the impact of the profitability, size dan liquidity to capital structure of the manufacturing firm listed in Indonesia Stock Exchamge. Samples are taken by using purposive sampling method and research has been done on 105 observations. The result show that profitability and size do not have significant impact on firm capital structure. On the other hand, liquidity has significant impact on capital structure. The next research is suggested to be done by different sectors of the firm and use more variable independent in a longer period of time to get a more comprehensive result.Keywords: capital structure, profitability, size, liquidit
