Abstract

The use of media through the Android application is still limited, even though it is needed to foster interest in learning after the COVID-19 pandemic. The research focused on increasing learning interest through the application of the Android-based Word Square learning media. This experimental research used a pretest-posttest control group design. The population in this study were all students of class IX MTs Guppi Samata, which consisted of 2 classes. The saturated sampling method was used in the sampling procedure with six samples taken from the experimental class IX-A and six samples taken from the control class IX-B. The research instrument was a questionnaire consisting of 30 items. The data analysis technique used the Wilcoxon signed ranks test. Students' learning interests differed depending on whether or not they used the Android-based Word Square learning media (p = 0.046, p 0.05). The results showed the differences in students' interest in learning with and without using the media of Word Square learning media based on android human reproductive system material for class IX MTs Guppi Samata (p = 0.046, p < 0.05). The average interest in learning among students through the media was 114.83. The value was higher than those without using the media (106.50). This proves that Word Square learning resources based on Android can increase students' learning interests. The findings of this study can be used to inform teachers' decisions about how to use engaging learning technologies and a variety of media to enhance the quality of their instruction.

Abstract

Tinea pedis is a type of superficial mycosis. Tinea pedis is a dermatophyse that is most often found in humans and is usually called water fleas. Lack of maintaining cleanliness and wearing closed shoes is one of the factors that causes Tinea pedis. Tinea pedis usually affects adults who work in wet or humid places, such as car and motorcycle washers, garbage collectors and farmers. When doing activities, the average farmer uses boots for too long. However, some farmers who do not wear boots while working experience itching on the soles of their feet. This research aims to determine the prevalence of fungal contamination that causes water fleas (Tinea pedis) in farmers in Tegalharjo village, Banyuwangi Regency. The population of this research are 30 farmers in Tegalharjo village, while the research sample Is skin scrapings between the toes of the farmers. Then the sample obtained is directly examined by using a microscope and 10% KOH reagent. The results shows that the farmers who are contaminated with the fungus that caused Tinea pedis are 6 people with a percentage (20%) and 24 people who are not contaminated with a percentage (80%). The incidence of infection Tinea Pedis among farmers in Tegalharjo Village, Banyuwangi Regency is also influenced by the duration of working in a day and the habit of wearing boots.

Abstract

This study aims to evaluate the effects of combination of glucomannan and anthocyanin in feeds containing protein microparticles on fat digestibility and fat deposition in broiler chickens. The 216 healthy 7-day-old broiler chicks strain CP 707 was used with treatment of glucomannan from porang tuber extract and anthocyanins from purple sweet potato extract. The study was arranged by a completely randomized design (CRD) with a factorial pattern with treatment consisting of 2 factors (A and B). In A, there were 3 glucomannan treatments, A1 (0%), A2 (0.05%) and A3 (0.1%), while in B contained 3 anthocyanin treatments, B1 (0), B2 (0.07%) and B3 (0.14%) with 3 replications. The measure was fat digestibility, precentage of abdominal fat and meat fat mass. The data were analyzed for variance at the 5% level and continued with Duncan's double test at the 5% level. The results showed that the addition of a combination of glucomannan and anthocyanin in the feed containing protein microparticles had an interaction (P<0.05) on fat digestibility, meat fat mass and relative weight of abdominal fat in broiler chickens. The addition of a combination of 0.1% glucomannan and 0.14% anthocyanin (A3B3) in the feed containing microparticle protein was able to reduce fat digestibility, relative abdominal fat weight and meat fat mass in broiler chickens.

Abstract

Culex quenquefasciatus is a mosquito that acts as a vector of filariasis disease. In Indonesia filariasis is still one of the endemic diseases. This proves that the handling of vector Culex quenquefasciatus is still not done optimally. One way that can be done to control mosquito vectors one of them is to use larvacide. Larvacide which is widely used today is still synthetic. Although very efficient in causing mosquito mortality, larvacide synthesis harms the environment and can cause vectors resistance. Then another larvacide alternative is needed that is effective and does not cause negative effects. Plants can be a choice of larvacide from nature. The study aims to find out the potential of the water extract of bay leaves and papaya leaves in killing the larvae of the Cx. quenquefasciatus mosquito as well as the value of LC50 after 24-hour observation. The type of research used is experimental research. The concentration of the water extract of bay leaves and papaya leaves used is 10%, 30%, 50%, 70%, and 90% with trhee times replication. LC50 is calculated using the Finney formula (1971), the calculation is carried out using application SPSS statistical version 26. Based on the research conducted, the value of bay leaf water extract LC50 = 62.89 g/ml and papaya leaf water extract LC50 = 45.10 g/ml. So based on the LC50 value, ita can be concluded that papaya leaf water extract is more effective in causing mortality Cx. quenquefasciatus compared with bay leaf water extract.

Abstract

The use of student’s worksheets as teaching materials and supporting learning activities is still not evenly distributed. The components are sometimes incomplete. This study aims to describe the development and determine the feasibility of guided inquiry-based worksheets as teaching materials for the endocrine system sub material for second-grade of high schools. This study used a 4D development model limited to three defining, designing, and developing stages. The student’s worksheets were designed based on the problems obtained from interviews with biology teachers in three different schools. At the development stage, the worksheets were validated by five validators consisting of two lecturers and three biology teachers in Pontianak. The validation assessment contained four aspects: the feasibility of the content/material, language, presentation, and graphics with 19 criteria. The student’s worksheet was successfully developed with enrichment in the form of discourse analysis activities related to diabetes and the process of lowering blood sugar levels by plant extracts with guided inquiry stages. The feasibility analysis results of the guided inquiry-based student’s worksheet obtained CVR and CVI values of 1 each so that product can be declared ready for the limited and extensive trial phase. However, the significance of the enrichment topics in this student’s worksheet still needs to be re-examined directly in the teaching and learning process in the Endocrine System Sub material for second grade of high school in both small and large scales groups.
