Construction of a hull generally requires several plates and profile material. Early indications for shipbuilding indicate that in manner, the linear function approach for installed material was 75% to 90%, and waste material was 10% to 25%. This study is conducting an assessment of the area of installed material and waste material on small vessels made of aluminum with variations in ship length and the method of approach trend lines both linear and nonlinear. Secondary data retrieval in the form of an aluminum cutting plan for plate material and profile from the AutoCAD application, which is then reprocessed through the FastCAM application to obtain results in the form of identification of installed material and waste material area. Based on variations in ship length and material area results, a scatter plot process was carried out through the Excel application to obtain results in the form of trend line functions with an R-squared determination coefficient of more than 0.9 and the results of the calculation of the intersection between the function of installed material and waste material, and the waste material function with the x-axis uses the balance method. The final result showed that the linear function gives an indication of the effectiveness of the material located in the range of 6 to 23 meters in length of the boat and polynomial function of order 2 in the range of 6 to 18 meters in length, while the waste material area in the two functions maximum 22%.

Ambon City is a region consisting of hilly areas and steep slopes with diverse river characteristics. Research has been carried out in the Wae Ruhu watershed in Ambon City which starts from upstream (water catchment) to downstream. This study aims to determine the magnitude of river discharge and sediment discharge in the Wae Ruhu watershed. This research was conducted in several stages including, secondary data collection, research location survey, preparation of research tools and materials as well as field data retrieval processes which included tracking coordinates at each station point and entire watershed, calculation of river flow velocity, river geometry measurements, and sampling sediment. The results showed that the average river discharge in the Wae watershed in the year 2018 was 1.24 m3 / s, and the average sediment discharge was 6.27 kg / s. From the results of this study and the field observations proposed for flood prevention and the rate of sediment movement are the construction of cliffs with sheet pile and gabions.

Simulation Results

An asymmetric Prandtl–Ishlinskii (API) hysteresis model for a giant magnetostrictive actuator (GMA) is proposed in this paper. The classical Prandtl–Ishlinskii (PI) model is analyzed and divided into two parts: linear function and operator summation. To enhance model asymmetry, a polynomial function is used in the API model as the center curve of the hysteresis instead of the linear function. The remaining curve of the hysteresis is modeled by a new operator that provides some basic asymmetric hysteresis. In this manner, the proposed API model requires relatively less operators and fewer parameters to describe the asymmetric hysteresis behavior of the GMA. All parameters of the API model are identified by a standard least square method. Simulation results show that the API model is very successful in formulating an asymmetric hysteresis of the GMA. In addition, it provides better identification results compared with the classical PI model.

This study aims to determine whether there is influence over land tenure status to the income of rice farmers. Data retrieval is done with primary data and secondary data. Primary data were obtained from the farmers through a list of questions that had been prepared, while secondary data obtained from the office of the village or the head of the village. The way of taking samples, to look at the total population of each of the existing land tenure status, then divided by the population over land ownership and divided by 60 as a sample to be taken. The data collection method used is descriptive analysis and ANOVA (analysis of variance) in one direction. The concepts of measuring variables used are over land ownership, production, farming costs, revenue and income. The results of this study indicate that there are significant land ownership to farmers' income, the highest income is income tenants. Different income is the income of farmers own property with tenant farmers' income.

The research aimed at finding out speaking ability of second grade elementary students by using Think Talk Write learning model. The data retrieval was carried out for four days. The problem was lack of teachers’ innovation in improving students’ speaking ability so the researcher decided to carry out this model. The research method was descriptive qualitative. Primary data was taken from this research result and secondary data was taken from published journals. Data analysis techniques were triangulation and data reduction from interview, observations, students’ activities, and students’ presentation results. The result of this study showed that on the first day of observation the students were still in low category, while on the second day to the fourth day, 25 students were in fast category and only 2 students were in medium category. Based on this result, it can be concluded that Think Talk Write learning model can improve speaking ability of second grade elementary students.
