Determinan Capaian Pembangunan Kabupaten/Kota Jawa Tengah Tahun 2019

In 2019, Badan Perencanaan Pembangunan Nasional (Bappenas) awarded Central Java as the province with the best Perencanaan dan Pembangunan Daerah (PPD). However, if it is reviewed at the district/city level, it shows that there are still many areas that have low development achievements. In accordance with the United Nations Development Programme (UNDP) proposal, the Human Development Index (HDI) is used as an indicator of the achievement of district/city development whose calculations are good enough to describe development from both a social and economic perspective. The large difference in HDI between districts/cities in Central Java and the distribution of development achievements are still centered around the provincial capital, namely Semarang City, this indicates the occurrence of inequality in development achievements at the district/city level in Central Java. Because the observations in this study are districts/cities in Central Java, the linkage between district/city causes spatial autocorrelation. Therefore, spatial regression model is used to determine the model that has spatial autocorrelation. This study aims to determine the achievements of development and its determinants in the districts/cities of Central Java in 2019 using the spatial regression analysis method. From the results of the study, it is known that there is a dependence on development achievements between districts/cities in Central Java which is influenced by the regional capacity factor is characterized by PAD and economic growth; operational resource factors characterized by DAU, DAK and technology; and the level of poverty.Pada tahun 2019, Badan Perencanaan Pembangunan Nasional (Bappenas) memberikan penghargaan kepada Jawa Tengah sebagai provinsi dengan Perencanaan dan Pembangunan Daerah (PPD) terbaik. Namun apabila ditinjau pada tingkat kabupaten/kota menunjukkan bahwa masih terdapat banyak daerah yang memiliki capaian pembangunan yang rendah. Sesuai usulan UNDP, Indeks Pembangunan Manusia (IPM) digunakan sebagai indikator capaian pembangunan kabupaten/kota yang penghitungannya sudah cukup baik menggambarkan pembangunan baik dari sisi sosial maupun ekonomi. Besarnya perbedaan IPM antar kabupaten/kota di Jawa Tengah dan sebaran capaian pembangunannya masih berpusat di sekitar ibu kota provinsi yaitu Kota Semarang, hal ini mengindikasi terjadinya ketidakmerataan capaian pembangunan pada level kabupaten/kota di Provinsi Jawa Tengah. Penelitian ini bertujuan untuk mengetahui capaian pembangunan dan determinannya di kabupaten/kota Jawa Tengah tahun 2019 dengan metode analisis regresi spasial. Dari hasil penelitian diketahui bahwa faktor kemampuan daerah yang dicirikan oleh PAD dan pertumbuhan ekonomi; faktor sumber daya operasional yang dicirikan oleh DAU, DAK dan teknologi; serta tingkat kemiskinan signifikan memengaruhi capaian pembangunan

PENGARUH PENGENCER KUNING TELUR AYAM DENGAN AIR KELAPA MUDA TERHADAP INTEGRITAS MEMBRAN PLASMA DAN ABNORMALITAS SPERMATOZOA DOMBA SAPUDI

This study aimed to determine the influence of mixture diluter of chicken egg yolk and young coconut water on the integrity of plasma membrane and abnormalities of Sapudi sheep spermatozoa. The experimental design used in this study was a complete random method. The data was analysed using ANOVA, and if there is a significant difference then proceed with Duncan’s Multiple Range Test( DMRT ) at significance level of 5%. Based on the result of the research, the influence of mixture diluter of chicken egg yolk and young coconut water was not significantly different ( p> 0,05 ) on the intact plasma membrane of spermatozoa on the first day until the fourth day. Interaction between treatment and storage duration had no effect on spermatozoa abnormality on the first day, second day and the fourth day. It can be concluded that mixture diluter of chicken egg yolk and young coconut water had a good effect on the plasma membrane and spermatozoa abnormalities up to the third day

Quorum Sensing as a long-range interaction for bacteria growth and bioluminescence

We study the role of Quorum Sensing (QS) in the growth of bacterial colonies and in the bioluminescence produced. These two phenomena are both regulated by QS and the experimental data show a non-trivial correlation between them. It is also known that the specific bacterial substrate potentially modifies the behavior of the colony. In the specific case of the bioluminescent gram-negative bacterium, Vibrio harveyi, we propose a three-autoinducer model in which QS is described in terms of long-range interaction between charged objects placed on a regular network and playing the role of bacteria. The charges spread in the network through fictitious non-linear electrostatic interactions. QS is monitored by analyzing the current flowing within the network. The model parameters are determined by comparing the simulations with the data present in the literature and related to liquid cultures. New colony growth measurements are then performed on Vibrio campbelli (a member of the clade Harveyi) grown on hydroxyapatite (HA) substrates relevant for biomedical applications. Growth on the substrate differs from growth in liquid culture, although the observed bioluminescence is similar. We exploit our model to understand the differences between colonies in liquid culture and on substrate in terms of the relative role and cooperation of the three autoinducers.Comment: 8 pages, 5 figure

Impurity-vacancy complexes and ferromagnetism in doped sesquioxides

Based on hybrid density-functional calculations, we propose that ferromagnetism in the prototypical bixbyite sesquioxide In$_2$O$_3$ doped with Cr is due to Cr-oxygen vacancy complexes, while isolated Cr cannot support carrier-mediated magnetic coupling. Our proposal is consistent with experimental facts such as the onset of ferromagnetism in O-lean conditions only, the low or vanishing net moment in unintentionally doped material, and its increase upon intentional doping.Comment: 4 pages, 2 figure

Desain Pembelajaran Geometri Berbasis Teori Van Hiele dan Realistic Mathematics Education (RME) pada Kemampuan Visualisasi, Analisis dan Abstraksi Peserta Didik Sekolah Menengah Pertama (SMP)

Hasil studi pendahuluan menunjukkan bahwa pada proses pembelajaran geometri khususnya materi bangun ruang sisi datar di sekolah menengah pertama cenderung menggunakan rumus secara langsung dan penyajian materi yang tidak berkaitan dengan pengalaman kehidupan sehari-hari sehingga belum mampu mengembangkan kemampuan berpikir geometri serta belum menumbuhkan motivasi peserta didik terhadap matematika. Hal tersebut mendasari untuk mendesain alur belajar dalam bentuk aktivitas berdasarkan pengalaman peserta didik (experience-based activities). Penelitian ini dilakukan guna menghasilkan desain pembelajaran geometri materi bangun ruang sisi datar berbasis Teori van Hiele dan Realistic Mathematics Education (RME) yang memenuhi kriteria valid, praktis dan efektif bagi peserta didik Sekolah Menengah Pertama (SMP). Secara operasional, desain pembelajaran terwujud dalam Hypothetical Learning Trajectory (HLT) pada buku pegangan guru dan buku pegangan peserta didik. Penelitian ini merupakan design research yang mengkombinasikan model Plomp dengan model Graveimeijer & Cobb dengan 3 tahap. Pada tahap pertama dilakukan penelitian pendahuluan (preliminary research) yang terdiri dari dari analisis kebutuhan, analisis kurikulum, analisis konsep, analisis karakteristik dan literature review. Pada fase kedua dilakukan tahap pembuatan prototipe (prototyping phase) dengan serangkaian formative evaluation: self evaluation, validasi ahli, one-to-one evaluation dan small group. Selanjutnya fase ketiga dilakukan tahap penilaian (assessment phase) melalui field test dan melakukan refleksi terhadap alur belajar peserta didik. Subjek penelitian adalah peserta didik kelas VIII SMP Negeri 1 Padang, SMP Negeri 7 Padang dan SMP Negeri 25 Padang. Teknik pengumpulan data yang digunakan adalah wawancara, observasi, angket dan tes. Teknik analisis data yang digunakan adalah teknik analisis deskriptif. Hasil penelitian menunjukkan bahwa desain pembelajaran geometri materi bangun ruang sisi datar berbasis Teori van Hiele dan RME sudah valid, praktis dan efektif. Valid dari segi isi, bahasa, penyajian dan tampilan. Praktis dari segi daya tarik, proses penggunaan, kemudahan penggunaan, alokasi waktu dan ekivalensi produk. Efektif dari segi dampak potensialnya terhadap kemampuan berpikir geometri peserta didik serta dapat meningkatkan motivasi peserta didik dalam pembelajaran geometri. The previous studies showed that in geometric learning process especially on polyhedra material in junior high schools tended to use direct formulas and its contents were not related to students’ experiences in their daily lives, so it could not be able to improve students’ geometric thinking, and did not make them motivated on mathematics yet. It became the very basic reason why a learning cycle based on students’ experience activities was design. This study aimed to produce Local Instructional Theory (LIT) geometric learning on polyhedra material based on Van Hiele’s theory and Realistic Mathematics Education (RME) which met valid, practice, and effective criteria for junior high school students. Optionally, the LIT design will be used as a handbook by teachers and students. This research is a combination of Plomp and Graveimeijer & Cobb model which consist of three phases. On the first phase, a preliminary research was conducted that consisted of needs, curriculum, concepts, characteristic analysis and literature review. On the second phase, a prototype was design with several formative evaluations: self-evaluation, expert validity, one-to-one evaluation, and small group. The third phase was assessment through a field test by doing reflection toward students’ learning cycle. Subjects of this research were students in Junior High School 1 Padang on eight grade, Junior High School number 7 and 25 Padang. The data collection techniques used in this study was interviews, observations, questionnaires, and tests. After that, the data were analyzed by using descriptive and statistics test. From the research done by using LIT based on Van Hiele’s theory and RME, it showed valid criteria with characteristics: activities in LIT facilitated the students to do vertical and horizontal mathematics process, interactive, students-based, and reflected their art of knowledge from RME. The research product also met the practice criteria which LIT could be applied in all levels of students, helped them to find the concepts, develop their geometric thinking, and the time provided was fair enough to reach the learning goals. LIT based on Van Hiele’s theory and RME met the affective criteria which gave positive effect toward students’ geometric thinking to motivate them in learning geometry
