Tamarind (Tamarindus indica) is a versatile plant, findable in Indonesia (Java, Bali, North Sumatra, West Kalimantan, and South Sulawesi). The leaves are green to brown, round, 1-2.5 cm long and 4-8 mm wide, rounded tips, rounded base of blades, and flat edges. The content contained in tamarind leaves such as flavonoids, tannins, saponins, and alkaloids is believed to inhibit Propionibacterium acnes activity. This study aims to determine the effect of tamarind leaf extract ointment in controlling the growth of the bacteria Propionibacterium acnes that triggers acne. This study applied a Completely Randomized Design with 96% ethanol maceration method. Propionibacterium acnes was evidenced by the inhibition zone formed. The diameter of the inhibition zone of the 25% ointment was 1.235 cm, the 30% concentration was 1.385 cm, the 35% concentration was 1,680 cm, and the ointment base was 0 cm. The ANOVA test showed a significant value of 0.000<0.05, so there was a significant difference between the inhibition zone and the 95% confidence level. The results of Post Hoc test were P<0.05, meaning that there was a significant difference between the bases with formulas 1, 2, and 3. Thus, tamarind leaf extract ointment had a strong inhibitory effect on Propionibacterium acnes.

Banyak sektor yang terkena dampak era pandemi Covid-19, salah satunya adalah pendidikan. Menyikapi hal tersebut, Kementerian Pendidikan dan Kebudayaan mengeluarkan kebijakan untuk melakukan pembelajaran jarak jauh guna mencegah penyebaran virus corona. Pembelajaran Jarak Jauh dirancang bagi siswa untuk mengikuti diskusi yang telah diberikan oleh guru atau mengerjakan tugas dengan perangkatnya sehingga siswa akan terlatih untuk bekerja dan belajar secara mandiri dalam membangun pengetahuan. Namun terdapat permasalahan yang terjadi, seperti ketika dalam kegiatan belajar mengajar siswa cenderung aktif dalam kegiatan absensi dan aktif menjawab pertanyaan dengan jawaban ya dan tidak dan siswa kurang aktif jika diberikan diskusi oleh guru. Beberapa masalah tersebut dapat berdampak pada motivasi siswa. Salah satu solusi yang peneliti lakukan adalah menggunakan Whatsapp untuk berkomunikasi dengan siswa. Hal inilah yang melatarbelakangi penelitian untuk mengetahui pengaruh Whatsapp sebagai basis e-learning terhadap motivasi belajar siswa pada mata pelajaran biologi. Sampel penelitian adalah 167 siswa dengan teknik stratified random sampling. Teknik pengumpulan data menggunakan kuesioner dengan menggunakan skala diferensial semantik. Teknik analisis data menggunakan analisis data kuantitatif untuk mengetahui tingkat motivasi belajar siswa dengan uji prasyarat uji normalitas dan uji homogenitas. Hasil penelitian menunjukkan bahwa semua kelas memiliki tingkat motivasi belajar yang sangat tinggi, sehingga aplikasi Whatsapp memberikan pengaruh yang baik terhadap pembelajaran jarak jauh. The effect of whatsapp as the base of e-learning on student motivation in biology subjects in high school. Many sectors affected by Covid-19 pandemic era, one of them is education. In response to this, the Ministry of Education and Culture issued a policy to carry out distance learning to prevent the spread of the coronavirus. Distance Learning is designed for students to take part in discussions that have been provided by the teacher or do assignments with their devices so that students will be trained to work and learn independently in building knowledge. However, there are problems that occur, such as when in teaching and learning activities students tend to be active in attendance activities and actively answer questions with yes and no answers and students are less active if given discussions by the teacher. Some of these problems can have an impact on student motivation. One of the solutions the researcher did was using Whatsapp to communicate with students. This is the basis of the research to determine the effect of Whatsapp as a basis for e-learning on student motivation in biology subject. The samples were 167 students with a stratified random sampling technique. The data collection technique used a questionnaire using a semantic differential scale. The data analysis technique used quantitative data analysis to determine the level of student motivation with the prerequisite test for normality and homogeneity tests. The results showed that all class had a very high level of motivation to learn, so that the Whatsapp application had a good influence on distance learning.

AbstractThis research aims to identify the types of phytoplankton, identify the abundance of phytoplankton, and study the relationship between environmental factors and the abundance of phytoplankton. This research was carried out on January 10, 2023, at the Jenes River, Surakarta. Sampling was carried out at 3 observation stations to identify environmental factors (pH, DO, CO2, salinity, BOD, light intensity, temperature, and brightness). Observations were carried out at three stations, namely upstream, middle and downstream, namely, in the morning (06.00–07.00 WIB) and during the day (12.00–14.00 WIB). Measurements of environmental factors were carried out at the integrated laboratory at Sebelas Maret University, Surakarta. The results of the research showed that the phytoplankton found were 9 families consisting of 11 species with an average abundance of 6,834 individuals/L in the morning day and an average abundance of 13,088 individuals/L during the day. The most abundant phytoplankton in the morning observations was Ulothrix sp. Meanwhile, the most abundant phytoplankton in the afternoon observations was Chroococcus sp. This abundance is also influenced by environmental factors such as pH, DO, Salinity, BOD, CO2, and temperature. The research found that the middle station had the highest phytoplankton diversity index during the day (1.6), possibly because it was indicated to be lightly polluted, allowing the life of many phytoplankton such as Closterium sp. and Quadrigula sp. The highest abundance of phytoplankton in the morning is Ulothrix sp., in the afternoon, it is Chroococcus sp.AbstrakPenelitian ini bertujuan untuk mengidentifikasikan jenis fitoplankton, kelimpahan fitoplankton, dan analisis hubungan faktor lingkungan dengan kelimpahan fitoplankton di Sungai Jenes Surakarta. Penelitian ini dilaksanakan pada 10 Januari 2023 di Sungai Jenes, Surakarta. Pengambilan sampel dilakukan di 3 stasiun pengamatan untuk mengukur faktor lingkungan (pH, DO, CO2, salinitas, BOD, intensitas cahaya, suhu, dan kecerahan). Pengamatan dilakukan di tiga stasiun yaitu hulu, tengah dan hilir sebanyak 2 yaitu, pagi hari (06.00–07.00 WIB) dan siang hari (12.00–14.00 WIB). Pengujian faktor lingkungan dilakukan di laboratorium terpadu Universitas Sebelas Maret, Surakarta. Hasil penelitian menunjukkan bahwa fitoplankton ditemukan berjumlah 9 famili terdiri dari 11 spesies dengan rata-rata kelimpahan 6.834 individu/L pagi hari dan rata rata kelimpahan 13.088 individu/L pada siang hari. Fitoplankton yang paling melimpah pada pengamatan pagi hari adalah Ulothrix sp., sedangkan siang hari adalah Chroococcus sp. Kelimpahan ini juga dipengaruhi oleh faktor lingkungan seperti pH, DO, Salinitas, BOD, CO2 , dan suhu. Penelitian menemukan bahwa stasiun tengah memiliki indeks keanekaragaman fitoplankton tertinggi pada siang hari (1,6), kemungkinan karena terindikasi tercemar ringan, memungkinkan hidupnya banyak fitoplankton seperti Closterium sp. dan Quadrigula sp. Kelimpahan fitoplankton tertinggi pada pagi hari adalah Ulothrix sp., sementara pada sore hari adalah Chroococcus sp.

AbstractFive isolates of endophytic bacteria from the roots of klutuk and ambon banana plants produce indole acetic acid (IAA) hormone. However, the evidence of its potential as Plant Growth Promoting Bacteria (PGPB) has not been observed. Therefore, this study aims to determine the effect of bacterial isolate to increase the growth of rice and maize plants. The growth rates of bacterial isolates were measured before the inoculation into the plant root. The root inoculation was performed following a complete randomized design. Root inoculation was carried out using 5 isolates of endophytic bacteria in rice and maize plant seedlings, and the process was repeated 15 times (n=15). The growth of rice and maize plants was monitored from 1st day after planting (dap) to the 14th dap. The collected data were analyzed by student t-test with a significant level of 5% (a= 0.05). The results showed that the logarithmic phase of all isolates was reached at 4 to 16 hours and K10, K25, K35, K111, and A41 isolates increased the height of plants while the K111 isolate can significantly increase the plant height compared to the control. This experiment revealed that the endophytic bacteria from banana plants increase the rice and maize plant’s growth.AbstrakLima isolat bakteri menghasilkan hormon indole acetic acid (IAA) yang berpotensi memacu pertumbuhan tanaman. Namun, bukti empiris potensinya sebagai Plant Growth Promoter Bacteria (PGPB) belum didapatkan. Penelitian ini bertujuan untuk mengetahui pengaruh isolat bakteri terhadap peningkatan pertumbuhan padi dan jagung. Penelitian ini menggunakan metode eksperimen dengan desain rancangan acak lengkap dan setiap perlakuan diulang 15 kali (n= 15). Hasil pertumbuhan tanaman yang diinokulasi dengan isolat bakteri masing-masing dibandingkan dengan perlakuan kontrol. Sebelum perlakuan, tingkat pertumbuhan bakteri endofit diukur sehingga didapatkan fase logaritmik yang cocok untuk dilakukan inokulasi ke akar tanaman. Setelah perlakuan, pertumbuhan tanaman padi dan jagung dipantau dari hari ke-1 setelah tanam (hat) sampai dengan ke-14 hat. Data dianalisis dengan uji t dengan taraf signifikan 5% (α= 0,05). Hasil penelitian menunjukkan bahwa 5 isolat yang berasal dari tanaman pisang mengalami fase logaritmik pada masa inkubasi 4 hingga 16 jam dan semua isolat bakteri meningkatkan tinggi tanaman serta isolat K111 dapat meningkatkan tinggi tanaman secara signifikan dibandingkan dengan kontrol. Penelitian ini mengungkapkan kemampuan bakteri endofit dari tanaman pisang untuk meningkatkan pertumbuhan tanaman.
