Abstract

The Research is a correlational study that aims to determine the relationship between digital literacy and the social attitudes of students in learning biology. The research sample consisted of 35 students as participants with the sampling technique using purposive sampling. The digital literacy questionnaire consisted of 14 statements which the indicators were adapted from Paul Glister (1997). The calculation of the two variables uses a Likert scale. Hypothesis testing used Pearson bivariate correlation and linear regression test. Before testing the hypothesis, first the normality test and linearity test are carried out as a prerequisite analysis test. The results showed that there was a relationship between digital literacy and social attitudes (R = 0.492; R2 = 0.287) meaning that there was a contribution of digital literacy to the social attitudes of students in biology learning by 28.7%.Penelitian ini merupakan penelitian korelasional yang bertujuan untuk mengetahui hubungan antara literasi digital dengan sikap sosial peserta didik pada pembelajaran biologi. Sampel penelitian sebanyak 35 peserta didik sebagai partisipan dengan teknik pengambilan sampel secara purposive sampling. Angket literasi digital terdiri dari 14 pernyataan yangindikatornya diadaptasi dari Paul Glister (1997). Perhitungan kedua variabel tersebut menggunakan skala likert. Pengujian hipotesis menggunakan  korelasi bivariat Pearson dan uji regresi linear. Hasil penelitian menunjukkan ada hubungan antara literasi digital  dengan sikap sosial. Nilai koefisien korelasi (R) sebesar 0,492 yang berarti hubungan kedua variabel adalah sedang. Untuk nilai koefisien determinasi  (R2) sebesar 0,242 atau 24,2%. Hal ini menunjukkan bahwa variabel literasi digital memberikan kontribusi sebesar 24,2% terhadap sikap sosial  peserta didik pada pembelajaran biologi.Kata kunci: literasi digital, pembelajaran biologi, sikap sosial

Abstract

Chili is one of the important food ingredients. The lack of public knowledge about chili cultivation techniques and good land optimization makes people's interest to grow chili less. In addition, household organic waste management in Tasikmalaya, especially in Sukasari Village, has not been optimal. The objectives of this service activity are 1) To provide knowledge and skills about chili cultivation techniques; 2) Utilization of household organic waste through the technology of processing household organic waste into organic fertilizer that can have economic value (Osama biobased economy); and 3) Educate the public regarding the optimization of yard land. The partners in this activity are the Jaya Mukti Farmers Association and Mukti Farmers Group which are located in adjacent areas with a total of 32 people using a random sampling technique because the sample is homogeneous. The activities carried out were in the form of socialization, demonstration, and practicum on household organic waste processing technology (Osama), chili cultivation techniques and optimization of yard land, as well as distribution of seeds and fertilizers to the community. The data collection technique in this activity uses a questionnaire. The results of this service activity indicate that there is an increase in community knowledge and skills in chili cultivation and the use of household organic waste and home yards.

Abstract

The application of Euglena as a carbon capture organism has generated considerable interest among scientists. Through the photosynthesis process, many kinds of metabolites are produced by Euglena, such as lipids, proteins, and pigments. Due to the metabolites produced by Euglena, it is vital to optimize the carbon capture ability and cell growth rate by adding Zn2+ content and giving photoperiodic into Euglena culture. The purpose of this study is to identify the optimal photoperiod and Zn2+ concentration to increase the growth rate, biomass, and metabolite content of Euglena sp. This study is a laboratory experiment involving the cultivation of Euglena sp. in various photoperiod cycles (light:dark), namely 24:0, 12:12, 14:10, and 16:8. In addition, Euglena sp. was also cultivated using different concentrations of Zn2+ (0 ppm, 5 ppm, 10 ppm, and 15 ppm). The growth of Euglena sp. was monitored for 18 days before being harvested every three days to measure the research parameters, including primary and secondary metabolites. The results showed that the photoperiod treatment and various concentrations of Zn2+ had a significant impact (P<0.05) on the growth rate, biomass, lipid, carbohydrate, protein, chlorophyll, and carotenoid levels of Euglena sp.
