Taxonomy of Crustose Lichens in The Forest of Tahura R. Soeryo, Batu, East Java

Lichen is a symbiotic organism consisting of a photobiont (green algae or cyanobacterium) and a mycobiont (fungal). A taxonomic study of the crustose lichens in the forest of TAHURA R. Soeryohad been conducted based on morphological, anatomical, and chemical characters. In this research, we used the method of descriptive exploration to identify the crustose lichens and to study the distribution of the species in the forest of TAHURA R. Soeryo. Twenty species of crustose lichens with one unidentified species and one specimen identified to the group of family are reported. They are Graphina, Graphis, Phaeographis, Pertusaria, Pachyphiale, Phlyctis, Lepraria, Lecanora, Lecania, Cyphellium, and Megalospora. This research also found the new record species of Megalospora kalbii in Java. Crustose lichens are found in the areas with high light intensity of ≥ 1000 lux, average humidity of ≤ 90%, average temperature of18-190C, and at altitudes of ±1640 dpl. Graphina ruiziana could only be found at the altitude of ± 1780 dpl. The identification key to its species and distributions of other species are presented also in the article

The Development of a Physics Module Based on the SETS Learning Model to Improve Students' Conceptual Understanding

This study aims to produce a learning device in the form of a physics module based on SETS that is valid and practical to improve students' conceptual understanding. The type used in this research is Research and Development (R&D). Subjects of this study were teacher and students of class XI MIA 1 with a total of 31 subjects. The research procedure  is the 4-D model, namely define, design, develop, and disseminate. Due to time and cost limitations, this  research is limited to the develop stage. The research instrument used was a validity questionnaire, practicality, and a description of the conceptual understanding. Furthermore, data obtained were analyzed to see the validity and practicality of the module as well as an assessment of students' conceptual understanding of dynamic fluid material. The level of understanding of students' concepts is seen from the aspects of interpretation, exemplifying, explaining, and comparing. The results showed that the physics module based on the SETS developed was categorized as very valid with an average of 82.16 and in the very practical category with a percentage of 84.29. Then for understanding the concept of students obtained a score of 94.67 in the interpretation  aspect,  86.98 in the exemplary aspect, then 81.10 and 86.61 respectively for the aspects of explaining and comparing. Learning using a physics module based on SETS is very good to be applied in order to improve students' conceptual understanding of dynamic fluid material. This was proven by the increase in students' understanding of concepts in every physics learning meeting on dynamic fluid material

PREDIKSI JUMLAH PENUMPANG PESAWAT PADA MASA COVID-19 DENGAN METODE EXPONENTIAL SMOOTHING

Forecasting is a study that is still interesting today. With the forecasting method, a person can make predictions about something based on previously available data. In this study, will be carried out on the prediction of the number of airplane passengers on domestic during the COVID-19 period. The data taken is data on domestic airplane passengers at Minangkabau International Airport Padang city. Data by month for the period 2016 to 2020. The method that will be applied to the data is the exponential smoothing type forecasting method, especially the Single Exponential Smoothing (SES) and Double Exponential Smoothing (DES) methods. The results of the study concluded that if analyzed from the MAPE value, the DES method was better with a MAPE value of 77. However, if analyzed from the MAD and MSD values, the SES method was better with a value of 32609 and 2044501652, respectively. Furthermore, analyzing the prediction results of the two methods, it was obtained that for the first four months the DES method showed better results than the SES method. But two months later the SES method was much better

Penelitian ini dilaksanakan bulan Oktober 2015. Populasinya adalah seluruh siswa kelas VII MTs Baitul Kiromyang berjumlah 121 siswa terbagi menjadi 3 Kelas yakni satu kelas untuk melakukan uji coba validitas dan reliabilitas instrumen, dan dua kelas lainnya untuk melaksanakan metode yang telah ditentukan. Data yang diperoleh, dilakukan uji asumsi dasar menggunakan uji validitas dan reabilitas, setelah itu diuji normalitas dan homogenitas. Setelah diketahui bahwa data yang diperoleh berdistribusi normal dan homogen, selanjutnya dilakukan uji kesamaan dua rata-rata dengan hasil t = -1,762 di mana ttabel= 1,991. Kemudian dilakukan uji pihak kiri pada taraf signifikan 0,05 menunjukkan bahwa t hit>-ttabel= -1,762 > -1,991, berarti terima H0, dengan kata lain terdapat kesamaan rata-rata hasil belajar yang diajar menggunakan metode konvensional (ceramah) dan diajar menggunakan metode Team Accelerated Instruction (TAI) pada materi pokok bilangan bulat siswa kelas VII MTs Baitu Kirom Kecamatan Seputih Mataram Kabupaten Lampung Tengah Tahun Pelajaran 2015/2016
