Heading control of Autonomous Underwater Vehicle (AUV) using Model Predictive Control (MPC) gives a good performance. Varying the length of the horizon provides a variety of performance. This paper ...is made in order to find out how many optimal horizons are needed to obtain the highest efficiency of energy use in AUV. Test results show a positive correlation between the length of the horizon and the amount of energy used. The optimal horizon obtained is then tested on several different trajectories.
This study describes servant leadership in improving teacher performance and building student character at SMPN 7 Mataram. The research approach used is qualitative with the case study method. ...Interview techniques, observation, and documentation studies were used for data collection. Checking the validity of the data is done by testing credibility, transferability, dependability, and confirmability. The study results show that the servant leadership of school principals can improve teacher performance, especially in discipline, with several efforts, namely supervising, providing motivation and increasing specialisation, activating school MGMP activities, and holding workshops.
The psychological approach in Islamic studies has a significant role in explaining the external symptoms of religious people. Armed with psychological theories, it will be easy to know the level of ...religion a person understands, lives and practices. This paper aims to explain and analyze Islamic psychology based on a historical approach and analyze western psychology schools using an Islamic psychological approach. This study refers to the history of Islamic psychology from the 19th century to the modern era at this time, and also how the development of religious psychology. The results in this article are that humans have the potential to do good from the aspects of will, freedom, feelings, and thoughts to reveal the meaning of life based on monotheistic values ??so that humans are able to develop the potential and quality of Islamic life, namely by integrating the pyramid relationship between lust, intellect, and heart into the human psychological context based on the teachings of revelation that will give birth to a creative life as ordered by God in the Koran.
Using remote sensing of sea surface temperature (SST), sea surface height anomaly (SSHA) and chlorophyll-a (Chl-a) together with catch data, we investigated the detection and persistence of important ...pelagic habitat hotspots for skipjack tuna in the Gulf of Bone-Flores Sea, Indonesia. We analyzed the data for the period between the northwest and southeast monsoon 2007-2011. A pelagic hotspot index was constructed from a model of multi-spectrum satellite-based oceanographic data in relation to skipjack fishing performance. Results showed that skipjack catch per unit efforts (CPUEs) increased significantly in areas of highest pelagic hotspot indices. The distribution and dynamics of habitat hotspots were detected by the synoptic measurements of SST, SSHA and Chl-a ranging from 29.5° to 31.5°C, from 2.5 to 12.5 cm and from 0.15 to 0.35 mg m-3, respectively. Total area of hotspots consistently peaked in May. Validation of skipjack CPUE predicted by our model against observed data from 2012 was highly significant. The key pelagic habitat corresponded with the Chl-a front, which could be related to the areas of relatively high prey abundance (enhanced feeding opportunity) for skipjack. We found that the area and persistence of the potential skipjack habitat hotspots for the 5 years were clearly identified by the 0.2 mg m-3 Chl-a isopleth, suggesting that the Chl-a front provides a key oceanographic indicator for global understanding on skipjack tuna habitat hotspots in the western tropical Pacific Ocean, especially within Coral Triangle tuna.
When local wisdom is not preserved for the Millennials concerned, identity will disappear, therefore suffocating to determine the extent to which the millennial generation in Sidenreng Rappang ...Regency knows about the values of Nene Mallomo pappaseng. This research is qualitative with an ethnographic design. The research location focused on three Sidenreng Rappang Regency sub—districts— data collected through observations, semi-structured interviews, and documentation. The object of the study was millennia. Object selection uses purposive techniques and snowball sampling. The results showed that the millennial generation in Sidenreng Rappang Regency knows well the values of Nene Mallomo's pappaseng, which consists of lempu (honest), acca (bright), warani (brave), and getteng (opinionated). Parents, family, teachers, and the community around their home are essential in socializing these values to millennials. The school is one of the media that emphasizes their knowledge about the values of Nene Mallomo's pappaseng because it is integrated into the subject matter of local content. The condition suggests that the preservation of local wisdom needs to be strengthened in the surrounding environment so that foreign cultures do not corrupt the identity of a region.
