Abstract

Student Worksheet (LKPD) is a practical guide in science learning. The existence of LKPD makes practicum activities can be carried out properly and structured. However, in biology lessons, especially the LKPD of the human respiratory system, the practicum of measuring lung capacity in the field is still not appropriate. Therefore, this study aims to reconstruct the LKPD on the human respiratory system material about practicum measuring lung capacity. This research uses the ANCOR (Analysis, Trial, and Reconstruction) stages. This study uses a quantitative descriptive method. The sample in this study amounted to 8 samples of LKPD selected using purposive sampling technique. The instrument used consists of 3 components, including: conceptual analysis, analysis of knowledge construction based on the Vee Diagram adapted from Novak and Gowin (1984), and practical analysis. The results showed that there were still various problems in conceptual analysis, knowledge construction analysis, and practical analysis. In addition, the results of trials related to practicum measuring lung capacity there are still unclear work procedures, as well as practicum tools used to measure lung capacity have weaknesses and are less accurate in data acquisition. So that there is a need for a better LKPD reconstruction, constructing student knowledge, and in accordance with the basic competencies in the applicable curriculum. Meanwhile, to overcome the weakness of the practicum tool, the researchers made an alternative simple tool to measure lung capacity that can develop the HOTS ability of students.

Abstract

East Teba Village has limited water availability due to the relatively long duration of the dry season, so the villagers use rainwater puddles for various activities, including consumption (source of drinking water) for livestock. This study aims to determine the quality of water in puddles of rainwater for consumption (source of drinking water) livestock. This research is quantitative descriptive. The sampling point of the test is the point where livestock drink water. Sampling test based on SNI 6989.57:2008 regarding the method of sampling surface water. The test result data is compared with the quality standard and the quality status is calculated using the pollution index method. The results showed that the TSS value had exceeded the class 2 and class 3 quality standards, while the BOD value had exceeded the class 2 quality standard and still met the class 3 quality standard. The parameter index value obtained was 2.20 which was classified as lightly polluted. The water in the puddle cannot be consumed by livestock, because the water does not meet the quality standard based on the calculation of the quality status using the pollution index method.

Abstract

This study aims to: 1) obtain growth regulators that are easy to obtain at low prices, because synthetic growth regulators are relatively expensive for novice researchers and are very difficult to obtain; and 2) to find out whether household waste can be used as a plant growth regulator in vitro which has been widely used and has been successful conventionally in several types of plants. The method used in this study was experimental, using a completely randomized design (CRD) with three replications. The media used was MS media by adding growth regulators from household waste with a concentration of (0-3) mg/L. The parameters in this study were the number of shoots and roots. The data obtained were then analyzed qualitatively, because the resulting data was not normal and not homogeneous. The results showed that the highest number of shoots was at a concentration of 2 mg/L organic waste growth regulator, with 5 shoots and 15.7 roots, with 8 days after planting on chrysanthemum growing media.

Abstract

Learning resources are one of the important things in improving the learning process. One of the material for high school class X that requires learning resources that come from the environment is the material on biodiversity. Learning practices in schools generally still use conventional learning resources, and have not used the environment as a learning resource. The purpose of the study was to analyze the requirements of biology learning resources based on research results from literature studies. This research is a literature study research, which is looking for relevant references to research on the Literature Study of Gastropod Diversity Level as a Biology Learning Source for Class X High School on Biodiversity Material. Data analysis used is descriptive qualitative analysis with narrative review method. This study uses 10 scientific articles on the diversity of Gastropods. The results of the study through a literature study found that the Gastropod diversity index had a diversity index of high category H' = 3.0468 and 3.0075. Medium category gastropod diversity index H' = 1.9915; 1,695; 1.5858-1.18742; 2,412; 2.232; 2,059; 1.4786-1.9382; 1,226; 1,251; 2,236; 1.22; and 1.39. Low category gastropod diversity index H' = 0.296; 0.180; 0.972; 0.113; and 0.668. The results of the analysis of the potential requirements for learning resources that have been carried out show that the results of research on gastropod diversity meet the requirements as a source for learning biology in high school class X on the subject of biodiversity.

Abstract

The study was conducted to determine the effect of several compositions of growth regulators (PGR) on germination and shoot initiation of dates (Phoenix dactylifera L.) in vitro. The study consisted of 2 experimental stages. The first phase of the study was aimed to determine the effect of the addition of Gibberellin PGR on the length of time the sprouts appeared, the number of explants that germinated, and the length of the sprouts produced. The second stage of the research was to determine the combination of PGR Indhol Acetic Acid (IAA) and Benzyl Amino Purine (BAP) which was able to initiate the emergence of shoots in the hypocotyl of dates. The study was designed using a completely randomized design (CRD). The first experiment consisted of 3 media treatments, namely: agar without additional ZPT (GA0); agar medium with 50 ppm GA (GA1); and agar medium with 100 ppm GA (GA2). Each media treatment consisted of 5 seeds and was repeated 3 times. The second stage of the experiment was designed in a completely randomized design with 5 media treatments, namely: P0 (MS medium without PGR); P1 (MS + 1 ppm IAA + 1 ppm BAP); P2 (MS + 2 ppm IAA + 1 ppm BAP); P3 (MS + 3 ppm IAA + 1 ppm BAP); P4 (MS + 1 ppm IAA + 2 ppm BAP); and P5 (MS + 1 ppm IAA + 3 ppm BAP). Each treatment consisted of 5 explants and repeated 3 times. Parameter observation data were analyzed by Analysis of Variance (ANOVA) and if significant results were obtained, continued with the Least Significant Difference (BNT) further test. The results of the first experimental data analysis showed that the treatment with 50 ppm GA3 significantly shortened the time of emergence of sprouts to 10 days and the number of explants that germinated on average was 4.5 explants. The results of observations and data analysis in the second experiment showed that the combination of IAA and BAP ZPT were significantly able to induce shoot formation on P4 and P5 media, which were 2.83 and 1.3 explants that formed shoots, respectively. Treatment with P4 was able to significantly increase the number of shoots produced by an average of 2.63 shoots per explant.
