Irrigation in Tanoh Abee is used for agricultural activities especially during the second planting season during dry season. However, the availability of irrigation water is controlled by total rainfall received. An accurate prediction of rainfall, which traditionally used “keneunong” local wisdom, is urgently required. The objective of the study is to obtain the best predictor of seasonal rainfall based on the Pacific sea surface temperature (SST) anomaly and the monthly lead time of prediction. We employed monthly rainfall from six stations surrounding the study area and combined with principal component analysis to eliminate rainfall autocorrelation. Seasonal rainfall (quarterly average) was calculated from monthly data. The results showed that 1-month lead time strongly correlated to seasonal rainfall in Tanoh Abee (r<-0.7, α=5%) for the second planting period. On other hand, the 2-month and 3-month lead time were useful to predict seasonal rainfall in March-April-May (MAM) only. For April-May-June (AMJ) and May-June-July (MJJ), the correlation between SST anomaly and seasonal rainfall was weak. This finding indicated that the accuracy of prediction decreases with the longer lead time. Based on our analysis, coordinates of 170° E – 175° E; 5° N - 5° S in Niño 4 region have strongly correlated with seasonal rainfall in MAM, AMJ, and MJJ periods. Moreover, further research is necessary to combine any approaches that will improve our prediction skill for another 2- or 3-month lead time.

This study aims to determine the relationship between motivation and self-regulated learning through blended learning in the covid-19 era. This study is a quantitative study with correlation study type. Samples were taken using random sampling techniques from all 1st-semester students who took basic physics courses and obtained 67 students consisting of 3 classes. The data was collected using the instrument of motivation and self-regulated learning in the form of a questionnaire which was filled in by the students after participating in basic physics courses using blended learning. The data that has been collected is then analyzed for normality and linearity. The data shows the results are normally distributed and linear so that data analysis can be continued with hypothesis testing using the Pearson product-moment correlation test and the value of R = 0.897 is obtained which is then compared with the R table at a significant level of 0.05, namely 0.244. Because R (0.897)> R table (0.244), it can be concluded that there is a positive relationship between motivation and self-regulated learning with the correlation coefficient value is 0.897 which is classified as very strong. Therefore, students' motivation and self-regulated learning through blended learning in the covid-19 era have a very strong relationship. This could be of concern to teachers and lecturers as facilitators in learning in this Covid-19 era. It is hoped that interesting learning using a blended learning approach can be applied so that student learning motivation increases and has a direct effect on students' desire to manage their own learning.

The boat propellers are needed for fishing boats in Aceh Province, considering that most Acehnese people geographically live along the coastline. Their income apart from farmers is fishermen. Currently, the metal ship propellers are imported from outside Aceh Province, so metal casting technology is needed to produce these ship propellers. There is already a small-scale industrial for metal casting, and the location is in Baet Lampuot - Aceh Besar District. The metal casting industry is currently producing rencong souvenirs to support tourism. However, when the Covid-19 Pandemic hit Aceh in particular and Indonesia in general, there are needed an alternative metal production business with other types of product variants, one of which was a ship cast-propeller. Based on this, Mechanical Engineering and FKIP Physics Department of Universitas Syiah Kuala improve the rencong metal casting industry to develop its products, to produce ship propellers through the Higher Education Leading Community Empowerment Program (PPMUPT) funded by the Ministry of Research and Technology /National Research and Innovation Agency of the Republic of Indonesia (RISTEK/ BRIN). The ship propeller product developed from waste metal, it recycled through metal casting technology. So the program and technology developed, is very useful not only for growing the regional economy but also in terms of handling the environment by recycling waste metal. Therefore, the community service program carried out by Mechanical Engineering and FKIP Physics Department of Universitas Syiah Kuala is right on target and in line with expectations.
