Starch is known as a biodegradable raw material that can be degraded by bacteria and microorganisms in the soil. Starch has cellulose which is kind of plant cellulose. This study shows the biodegradation rates of plastic made from Ganyong Canna (Canna edulis Kerr) as a cellulose source which is added with nata de coco as a filler. The biodegradable plastic functional group was confirmed by using FITR. The results show that the O-H group of Ganyong Canna (Canna edulis Kerr) biodegradable plastic is located at wave number 3298.03 cm-1 and shifted to 3290.32 cm-1 after addition of nata de coco. The C-H bonds functional groups in Canna biodegradable plastics and nata de coco plastics are at wave numbers 2920.01 cm-1 and 2916.16 cm-1. While the C-O bonds functional groups in biodegradable starch plastics and nata de coco is shown at wave numbers 995.05 cm-1. The mechanical properties of biodegradable plastics testing are thickness, tensile strength, and elongation based on the ASTM method. The thickness is about 0.1005 mm, the tensile strength of biodegradable plastic is 4,3244 MPa and the elongation value range about 13.9639% while the WVTR range about 14.20 g/m² hours. The results show that the increase of the plastic degradation made from nata de coco occurs between 5% - 38% per days. It is faster than the plastic made from pure Ganyong Canna (Canna edulis Kerr) starch. These results indicate that nata de coco could be added in biodegradable plastic on packaging materials for better degradation.

Kelelawar merupakan satu–satunya mamalia yang memiliki kemampuan untuk terbang. Kelelawar dapat dibedakan berdasarkan ukuran tubuh dan jenis pakannya. Megachiroptera merupakan pemakan buah dan nektar umumnya memiliki ukuran tubuh yang besar, bola mata besar dan memiliki moncong seperti anjing. Sedangkan Microchiroptera merupakan pemakan serangga, dan memiliki ukuran tubuh yang lebih kecil, bola mata yang lebih kecil dan memiliki bentuk wajah yang beragam. Kelelawar umumnya ditemukan bertengger di gua. Namun tidak menutup kemungkinan terjadi peralihan tempat bertengger seperti yang ditemukan di PPKA Bodogol. Penelitian ini bertujuan untuk memberikan gambaran mengenai Microchiroptera di PPKA Bodogol melalui studi morfometri dan deskripsi bangunan bertengger pada kelelawar yang ditemukan di PPKA Bodogol.

The purpose of this study was to determine whether or not the social studies learning through e-learning based on google form on the learning outcomes of fifth graders at SDN 01 Kebondalem Pemalang. The research method used is quantitative research with research design using Pre-Experimental Design. The type of design used is a one group pretest-posttest design. The population of this research is the fifth grade students of SDN 01 Kebondalem Pemalang. Samples were taken by 36 students, with 11 male students and 25 female students using a non-probability sampling technique with saturated sampling type. Data collection techniques in this study were obtained through interviews, observations, tests and documentation. From the pretest value, it shows that the average value is 53.33 while the posttest value shows that the average value is 82.91 and based on the t-test analysis, it is obtained that tcount is 9.227 with t of 2.028. The learning outcomes of students before and after being treated are not the same. The analysis of learning mastery before being given treatment was 19%, while after being given treatment it was 83%.

Abstract. The Covid-19 pandemic has had an impact on Umrah travel agencies which are threatened with losses and bankruptcy due to the policy of canceling Hajj and Umrah departures. PT. Manajemen Mihrab Qolbi Bandung needs to get around this policy in the form of an adjustment strategy in order to survive and attract public interest even though there have been no pilgrims departing due to covid-19 pandemic. Based on these phenomena, the problems in this study are formulated as follows: (1) What are the obstacles experienced by PT. Managemen Mihrab Qolbi Bandung during the Covid-19 pandemic? (2) How is the adjustment strategy of PT. Managemen Mihrab Qolbi Bandung during the covid-19 pandemic?. The purpose of the study was to find out the constraints and determine the strategy for adjusting Mihrab Qolbi Bandung during covid-19 pandemic. This study uses a qualitative method with a case study approach. Data collection techniques were obtained from observation, documentation, and interviews. Based on the results of the study, it can be concluded that the problems of Mihrab Qolbi Bandung during the pandemic are the decrease in the number of registrants, delays in departure schedules, increase in the price of Umrah packages, reduction in salaries and employees, and limited company operations. The strategy used is an adaptive strategy of defenders strategy, prospectors strategy, reactor strategy and sharia marketing strategy through a marketing mix (Product, Price, Place, Promotion) which has a good impact, because it can minimize losses and attract public interest during the COVID-19 pandemic. Abstrak. Pandemi Covid-19 memberikan dampak terhadap biro perjalanan umrah yang terancam mengalami kerugian dan kebangkrutan karena kebijakan pembatalan keberangkatan haji dan umrah. PT. Manajemen Mihrab Qolbi Bandung perlu menyiasati kebijakan tersebut dengan bentuk strategi yang tepat agar dapat bertahan dan menarik minat masyarakat untuk Umrah meski belum ada keberangkatan jamaah akibat pandemi covid-19. Berdasarkan fenomena-fenomena tersebut, maka permasalahan dalam penelitian ini dirumuskan sebagai berikut: (1) Bagaimana kendala yang dialami PT. Manajemen Mihrab Qolbi Bandung pada masa pandemi Covid-19? (2) Bagaimana strategi penyesuaian PT. Manajemen Mihrab Qolbi Bandung pada masa pandemi covid-19?. Tujuan penelitian untuk mengetahui kendala dan menentukan strategi yang tepat oleh PT. Manajemen Mihrab Qolbi Bandung dalam menghadapi pandemi covid-19. Penelitian ini menggunakan metode kualitatif dengan pendekatan studi kasus. teknik pengumpulan data diperoleh dari observasi, dokumentasi, dan wawancara. Berdasarkan hasil penelitian dapat disimpulkan bahwa kendala Mihrab Qolbi Bandung pada masa pandemi yaitu penurunan jumlah pendaftar, penundaan jadwal keberangkatan, kenaikan harga paket umrah, pengurangan gaji dan karyawan, serta operasional perusahaan terbatas. Strategi yang digunakan adalah strategi adaptif jenis defenders strategy, prospectors strategy, reactor strategy dan strategi pemasaran syariah melalui marketing mix (Product, Price, Place, Promotion) yang berdampak baik, karena dapat meminimalisir kerugian dan menarik minat masyarakat pada masa pandemi covid-19.

Penelitian ini merupakan penelitian pengembangan (R&D) menggunakan model 4D, yaitu Define, Design Develope, dan Disseminate. Namun, pengembangan ini hanya pada sampai tahap Develope. Penelitian ini bertujuan untuk mengetahui karakteristik produk buku bacaan berjenjang dan mengetahui kualitas produk yang dikembangkan. Penilaian dilakukan melalui ahli materi, ahli media, dan guru IPA SD yang meliputi 9 aspek penilaian dengan menggunakan instrumen lembar penilaian skala 4. Hasil penilaian berupa data kuantitatif dan kualitatif yang kemudian dianalisis dengan pedoman kriteria penilaian ideal untuk menentukan kualitas buku bacaan berjenjang. Produk yang dikembangkan direkomendasikan untuk kelas IV tema 2 pokok bahasan energi dan kelas V tema 3 pokok bahasan sistem pencernaan manusia yang diberi judul “Yuk, Cari Tahu”. Karakteristik produk terdiri dari 20 halaman yang dikemas dalam bentuk cerita dan terdiri dari satu gambar tiap halaman. Berdasarkan penilaian ahli materi menunjukkan bahwa kualitas buku Baik (SB) dengan skor 2 dari total skor 2, penilaian ahli media menunjukkan bahwa kualitas buku Sangat Baik (SB) dengan skor 6 dari total skor 6 dan  penilaian guru IPA SD menunjukan bahwa kualitas buku Sangat Baik (SB) dengan skor 31,2 dari total skor 36 dengan persentase keidealan sebesar 87%.
