Abstract

Billygoat weed (Ageratum conyzoides) is mainly used to treat wounds and fever. People also do not understand the use of these leaves in the treatment to increase the platelet counts. The objectives of this research Objectives were to test whether the Billygoat Weed’s leaves can increase platelet count of male mice and to find out what is the most effective dose of the Billygoat Weed on the platelet count of male mice. This research was done by employing the true experimental approach with the completely randomized design which consisted of 5 treatments, namely the negative control (plain water), the positive control (acetylsalicylic acid), 1.68 mg/kgBW, 2.52 mg/kgBW, and 3.36 mg/kgBW on five mice in each treatment. The increase in the platelet counts, based on the results of One-Way ANOVA with a p-value of 0,0004, the Billygoat Weed extract was able to increase the platelet counts. Through further testing, the smallest significant difference showed that a dose of 3.36 mg/kgBW was effectively able to increase the platelet counts of male mice with an average of 11140.80/.

Abstract

Industrial Revolution 4.0 requires schools to produce graduates who are not only good in memorizing various materials, but also must have the skills to think critically. Problem-Based Learning (PBL) is one of the learning models that is deemed good in training students' critical thinking skills, including students in Islamic schools. The purpose of this research is to determine the effect of problem-based learning on students' critical thinking skills in Islamic schools. This type of research is a quasi-experimental with random sampling as the sampling technique. The research sample was 66 students. Data collection uses instruments in the form of description tests that are adjusted to the indicators of critical thinking skills. The research analysis technique used was the t-test to determine the effect of the problem-based learning model on students' critical thinking skills. The result of the research shows that the average score of the class where the critical thinking skills through PBL are applied is higher than the class that does not apply PBL. The result of the data analysis using the t-test obtained that the value of tcount bigger ttable is 4.119 > 1.997 with a significance level of 5 %, so it is said that the PBL model influences students' critical thinking skills. It is suggested to make PBL learning becomes a mandatory choice to be applied in the learning process with the learning steps that have an impact on the students' thinking process.

Abstract

Creative thinking skills are one of the primary skills in 21st-century. The purpose of this research was to determine the PjBL Model's effect on students' creative thinking skills in physics. This research was a quasi-experimental research. The population of this research was all tenth-grade science students of SMA N 2 Bandar Lampung. The instrument in this study was test instrument to measure students' creative thinking skills. Based on the data, the PjBL model affected the creative thinking skills of students in physics materials evidenced by the results of data analysis with a sig value of 0.00, which was lower than 0.05. Therefore, H1 was accepted or there were differences in students’ creative thinking skills. Therefore, it can be concluded that the PjBL model affects students' creative thinking skills on physics material. It is recommended for further researchers to apply the PjBL model to other learning materials.

Abstract

The purpose of this study was to determine the results of organoleptic tests on getuk lindri treated with natural dyes from telang flower (Clitoria ternatea L.), red dragon fruit skin (Hylocereus polyrhizus.) and black rice (Oryza sativa L.). the method used is by using a completely randomized design (CRD) using 4 treatments and 3 repetitions. Based on the results of organoleptic tests of Getuk Lindri products by utilizing several types of plants containing anthocyanin pigments, the quality standards are classified as good with natural dyes of dragon fruit skin. On the other hand, of the three types of plants that contain anthocyanin pigments, all three can be used as natural dyes that produce different colors. In addition, plants containing anthocyanin pigments used were able to inhibit bacterial growth, this was seen from the total plate number for each treatment which did not exceed the maximum limit of SNI 01-4299-1996 (getuk cassava).Abstrak Tujuan penelitian ini yaitu Untuk mengetahui hasil uji organoleptik pada getuk lindri yang diberi pewarna alami dari bunga telang (Clitoria ternatea L.), kulit buah naga merah ( Hylocereus polyrhizus.) dan beras hitam (Oryza sativa L.). metode yang digunakan yaitu dengan menggunakan Rancangan Acak Lengkap (RAL) dengan menggunakan 4 perlakuan dan 3 kali pengulangan. Berdasarkan hasil uji organoleptik dari produk getuk lindri dengan memanfaatkan beberapa jenis tanaman yang mengandung pigmen antosianin mempunyai standar kualitas yang digolongkan baik dengan pewarna alami kulit buah naga. Disisilain bahwa dari ketiga jenis tanaman yang mengandung pigmen antosianin ketiganya bisa digunakan sebagai pewarna alami yang menghasilkan warna yang berbeda. Selain itu tanaman yang mengandung pigmen antosianin yang digunakan mampu memperhambat pertumbuhan bakteri, ini dilihat dari angka lempeng total setiap perlakuan yang tidak melebihi batas maksimal SNI 01-4299-1996 (getuk singkong).
