<p>Marker assisted back crossing (MABC) is a molecular tool that can help breeders in reducing backcrossed generation. However, effectiveness of this method still needs further approval using actual phenotypic performances. The International Rice Research Institute had developed Ciherang near isogenic line (NIL) of submergence tolerance, Sub1. The study aimed to evaluate phenotypic performances of Ciherang Sub1 NIL in the greenhouse and field conditions. The study was conducted in ten locations using five submergence-tolerant varieties and a control treatment under normal conditions. The results showed that the average grain yields and some agronomic traits of Ciherang Sub1 were not significantly different compared with those of Ciherang (recurrent parent). However, under 10- and 15-days of submergence. Ciherang Sub1 was significantly different to Ciherang. The survival rate of Ciherang Sub1 was higher than Ciherang after 14-days submerged in the greenhouse tank experiment. Response of Ciherang Sub1 to brown planthopper biotype 1, 2 and 3, Xanthomonas oryzae pathotype III, IV and VIII, and rice tungro virus inocula from Subang, Magelang and Lanrang were also comparable with its recurrent parent. Quality and physico-chemical properties of rice (milled rice) of Ciherang Sub1 were not different with those of Ciherang. Similarity level of phenotypic traits of Ciherang Sub1 compared to Ciherang was more than 87.5%. This finding proved that a single backcross method can produce progeny identic with its parent. This MABC line can be recommended to farmers in flood-prone area where the Ciherang is preferred. </p>
Development of mobile learning application-based media.

Social studies learning in the revolutionary era 4.0 should use digital maps to visualize the conditions of the earth's surface so that students interpret social studies subject matter more clearly. This study aims to develop a map media product based on the android application "ethnic and cultural diversity". This type of research is research and development using the Borg and Gall model. The stages are (1) research and information gathering, (2) planning, (3) initial product development, and (4) preliminary testing. Collecting data in this study using a validation questionnaire of the feasibility of map media products based on android applications. Data analysis in this research is the feasibility analysis of map media products based on android applications. The result of this research is the development of map media based on android application material on ethnic and cultural diversity that is suitable for use in social studies subjects has been validated by experts and declared "feasible" to be used. The author suggests teachers use android-based map media development products for ethnic and cultural diversity in social studies subject for class VII SMP / MTs in order to answer the challenges of technology-based 21st century learning in the current era of industrial revolution 4.0
Building character was the educational function that must be achieved through the learning process both offline and online. Cooperation and good communication were needed between students, teachers and parents to overcome the kinds of obstacles. The competent teachers in providing learning experiences and methods were needed to make students enjoy learning. Parents' companionship and support were expected to have an impact on the development of independent and responsible character for their children. Various efforts in building independence and responsibility of students in online learning had answered in qualitative research conducted at SMAN 1 Tumijajar. The data was obtained by distributing questionnaires to parents, students and teachers through the WhatsApp group. Online interviews were conducted with students. The result showed that students' independence and responsibility had been developed trough the online learning.
Museum merupakan pustaka yang berfungsi sebagai tempat penyimpanan, pengamanan dan pemanfaatan benda-benda bukti material hasil budaya manusia, alam dan lingkungannya guna menunjang upaya perlindungan dan pelestarian kekayaan budaya bangsa, dan sebagai tempat sumber studi ataupun penelitian. Salah satu museum yang bersifat kedaerahan adalah Museum Kekhatuan Semaka yang berada di Kabupaten Tanggamus. Fakta Museum Kekhatuan Semaka dilapangan menunjukan bahwa bahwa benda-benda peninggalan sejarah masyarakat yang berada di museum belum terdokumentasikan dengan baik. Padahal di dalam museum tersebut telah terkoleksi ratusan benda warisan budaya dan sejarah peninggalan masa lalu. Informasi tentang koleksi benda Museum Kekhatuan Semaka hanya diperoleh secara oral dari pemiliknya atau pengelola, hal inilah menjadi kekhawatiran akan kelestarian koleksi di masa depan. Karena itu pelatihan tentang pembuatan naskah dokumentasi koleksi dan informasi benda-benda yang terdapat di museum Semakha menjadi sangat penting. Diharapakan melalui pendokumentasian yang baik, Museum Kekhatuan Semaka dapat menjadi sumber sejarah lokal dan destinasi objek wisata sejarah.
Soft skills in the teachers' professional development perspective. Objectives: This study aims to determine the role of soft skills in teacher professional development. Methods: This study used a survey method for a number of Social Sciences Education teachers in junior high schools. Data was collected using a questionnaire regarding teacher identity and soft skill instruments as a result of development that had been expertly tested and small group tests according to the Borg and Galls design. Findings: There was a significant relationship between age and the quality of soft skills scores (r =-0.292, p < 0.05.). In line with that, a negative correlation was also obtained between age and personal attributes (r =-0.287, p < 0.05. Conclusions: Soft skills tended to decrease for teachers as they grew older, the soft skills the teachers had differed in terms of rank and class and Soft skills were closely related to teacher professional development.
The capital market has a big role in the economy, some of these functions are as a means for companies to seek capital and also as an investment instrument for the community. In college, materials are usually taught about the capital market and other financial institutions. Therefore, students are considered to have sufficient financial literacy so that students can invest. However, the number of FEB students recorded in 2020 was 2038 people, while students who had RDN were only 49 people or 2.40% of the total FEB students. The analysis technique used in this research is multiple regression analysis, the sampling technique used is purposive sampling. with the desired respondent criteria in this study, including: 1. Active students of FEB UBPK; 2. Class of 2018, 2019, and 2020 students; and 3. Students who already have personal income. Based on the results of research conducted that the significance value of the influencer variable is 0.000 < 0.05 and the financial literacy variable has a significant value of 0.000 < 0.005. it can be concluded that the two variables have a significant positive effect on investment interest. Then simultaneously financial literacy variables and influencers have a significant effect on student investment interest.
