Abstract

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.

Abstract

One of the Basic Competencies (KD) in Biology for Indonesian Senior High School is KD 4.12 which reads "Presents observations of the process of mitosis in the onion root and determines the phases it finds". Based on the basic competency test, students are required to have skills in making and observing mitotic preparations of plant tissue with at least using onion. Observation of mitotic division in plant tissues requires skill in making preparations. Making preparations in observing cells and tissues of plants or animals needs staining. Dyes often used in lab work are synthetic dyes. One of the synthetic dyes commonly used is safranin. However, safranin is quite expensive. This limitation requires teachers to look for alternatives to synthetic dyes that are easily found at a more affordable price, namely with natural dyes. One of the plants that has the potential to overcome this issue is beetroot (Beta vulgaris). The purpose of this study was to determine the quality of plant tissue preparations (Allium cepa) stained with beetroot skin (Beta vulgaris) as a natural coloring agent. The research method used was an experimental method with a Completely Randomized Design consisting of two factors, namely the staining time (1 hour, 2 hours, and 3 hours) and the type of solvent (aquades and citric acid 10%). The results of the study were analyzed with qualitative descriptive methods which included contrast and clarity of the preparations. Based on the results of the study, the quality of Allium cepa root preparations using beetroot (Beta vulgaris) skin extract with variations in the type of solvent and duration of staining showed good results on the staining time of 1 hour and 2 hours. The staining time of the preparations can affect the contrast and clarity of the preparations.

Abstract

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.

Abstract

Samin is one of watersheds located in the districts of Karanganyar and Sukoharjo, Central Java, Indonesia. Samin is a part of Bengawan Solo watershed that is classified into one of 282 Indonesian watersheds which are in critical condition. Research about vegetation analysis of Samin watershed as conservation efforts have been done before and resulted in structure of lower crop community (LCC) and tree vegetation. The purpose of this study was to analyze potential plants, both LCC and trees, in Samin watershed that could be developed as a vegetative water and soil conservation. The list of plants that were potentially developed as a vegetative conservation obtained from the research before about analysis structure and composition of vegetation in Samin watershed and literature review. The result of this research showed that there were several plants with the highest Important Value Index (IVI) and that can be developed for vegetative soil and water conservation. In tree vegetation, there are Tectona grandis, Delonix regia, Switenia mahagoni, Cassia siamea, and Samanea saman. These tree plants have a big canopy that can retain rain water through several mechanismssuch as interception, reducing direct flow, and producing litter layer. In LCC vegetation, there were Mimosa pudica, Ageratum conyzoides, Tridax procumbens, Oplismenus burmanii, Chloris barbata, and Axonopus compressus. Grass vegetation could withstand runoff and increase infiltration.
