Abstract

Semanggi air jenis tumbuhan air tersebut termasuk gulma yang sering dijumpai di sawah atau rawa, yang mempunyai kemampuan hidup pada kondisi lingkungan dengan kualitas air yang rendah. Tujuan penelitian ini adalah  mengetahui efektivitas Semnaggi Air terhadap penurunan kadar TSS pada limbah cair tahu. Metode penelitian menggunakan metode eksperimen dengan desain Rancangan Acak Lengkap (RAL)terdiri dari empat varian biomassa Semanggi Air, yaitu 0 g, 25 g, 50 g, 75 dengan 4 perlakuan 3 kali ulangan selama 10 hari. Hasil penelitian menunjukan adanya nilai kadar TSS yang bervariasi dengan nilai TSS 268,7; 221,3; 263; dan 200,7. Dari perlakuan tersebut kadar TSS yang efektif untuk menurunkan adalah Perlakuan 3 dengan biomassa 75 gram mencapai 25%. Hasil uji Homogenitas varians menunjukkan keempat perlakuan evektivitas fitoremediasi tanaman semanggi air memiliki varians yang sama atau identik (homogen) dan analisis sidik ragam menunjukkan bahwa Fhitung > Ftabel 5% (4,07). Hal ini menunjukkan bahwa H0 ditolak dan H1 diterima yang menyatakan Tanaman semanggi air efektif digunakan untuk fitoremediasi limbah cair tahu. Kesimpulan dari penelitian adalah semanggi air efektif dalam penurunan kadar TSS limbah cair tahu.

Abstract

This study aims to determine the effect of variations in media bottle size on the growth of Phalaenopsis amabilis L. orchid plantlets. This study used a Completely Randomized Design (CRD) with variations in one factor, namely the size of the media bottle (P1: 250 ml, P2: 500 ml, and P3: 750 ml). Each treatment variation was repeated four times. The results of data analysis in this study used the SPSS 27 program. The data was tested for normality and homogeneity, then continued with the ANOVA (Analysis of Variance) test at the 5% level. If there is a significant influence then proceed with the Least Significant Difference (BNT) test. The results of the research showed that there was an effect of using variations in the size of the 750 ml bottle on the parameters of root length and number of roots. In conclusion, variations in the size of the planting medium bottle can influence the growth of Phalaenopsis amabilis L. orchid plantlets including root length and number of roots. Keywords: Tissue Culture, Phalaenopsis amabilis L., Bottle Size

Abstract

The 21st century require students to have skills in solving everyday problems as well as sustainability awareness. This awareness includes understanding, attitudes, and actions that support efforts to preserve the environment and sustainable development. The purpose of this study was to determine the profile of science process skills and sustainability awareness in students' ESD concepts. The method used in this research is descriptive. The samples in this study were students of class VIII B SMP Negeri 23 Semarang. The instruments used were multiple choice questions to measure the level of science process skills and questionnaires to determine students' sustainability awareness. The results showed that students' science process skills were still at a sufficient level with an average percentage of 61.97, while the percentage level of students' sustainability awareness was in the medium category with a percentage of 66.2. So it can be concluded that in science learning, there is a need for the science process skills approach and the application of problem-based learning models integrated with ESD in an effort to improve the science process skills and sustainability awareness of junior high school students. The demands of the 21st century require students to have skills in solving everyday problems and sustainability awareness. This awareness includes understanding, attitudes, and actions that support environmental conservation and sustainable development.

Abstract

Quality education is an important foundation for the progress of a society. However, the main challenge in the education system is to provide learning that is in accordance with the needs, interests, and potential of individual students. To overcome this, an inclusive learning approach is implemented, known as "Differentiated Learning". This learning emphasizes the recognition of diversity among students and efforts to adjust teaching methods to suit their needs. In addition, innovation in the use of learning models by teachers is important to create a pleasant learning climate and stimulate students to be more successful. The Community Partnership Program (PKM) aims to increase awareness of the Education community, especially teachers, of the importance of Differentiated Learning in improving the quality of education. Through a series of activities such as workshops on the preparation of tools and the implementation of Differentiated Learning in several schools as a method applied in this PKM to achieve significant results. The outcomes obtained include an increase in teacher understanding of the concept of Differentiated Learning, an increase in teacher competence in designing learning that suits student needs, and an increase in academic achievement and student welfare. With increasing teacher competence in preparing innovative and student-centered learning, it can have a positive and sustainable impact in creating an inclusive and diversity-oriented educational environment.

Abstract

When entering adolescence, physical growth and sexual maturation occur, if not equipped with positive values, it will have an impact such as free sex. The phenomenon of free sex is increasing due to the lack of understanding of the human reproductive system and religious values. The effort to overcome this is by integrating biology learning on the concept of human reproductive system with the values contained in the Qur'an. The purpose of this study is to analyse the potential application of Qur'an-based biology learning on human reproductive system. The type of research used is descriptive qualitative with a sample of MGMP biology teachers in Mranggen sub-district using random sampling method. Supporting data sources came from the opinions of students, teachers and Head of Madrasah at MTs Al Furqon. The data collection techniques used were questionnaires, observations and interviews. Descriptive analysis technique was used to describe the implementation potential. With a percentage of 100%, teachers think there is potential for Qur'an integration on human reproductive system lesson. From the results of the questionnaire, with a percentage of 80%, teachers think there is potential to implement Qur'an-based biology learning on human reproductive system for madrasah students. The results of observations on teachers, students, madrasah head and infrastructure at MTs Al Furqon show that there is potential to implement Qur'an-based biology learning on human reproductive system lesson. It is hoped that later it can also be implemented to other biological concepts.

Abstract

Catfish (Pangasius sp.) is a freshwater fish commodity that is widely cultivated in the Indonesian fisheries sector. The aim of this research was to determine the effect of fortification of liquid probiotics bioprisma and biogan on the protein and fat of catfish meat in the biofloc aquaponics technology. The catfish used in this study was 7-8 cm in size. The research was carried out using a completely randomized design (CRD) method with 3 treatments and 3 replications, the treatments were as follows: P0 = without addition of probiotics, P1 = addition of bioprisma probiotics 0.15 mL/l,5 L of water, P2 = addition of biogan probiotics 0,15 mL/l,5 L of water. The data obtained were then processed and calculated using ANOVA at a 95% confidence interval if a significant effect was found, then continued with Duncan's further test. This study indicates that the addition of probiotic to catfish culture media can affect body protein, body fat, and water quality environmental condition (ammonia, nitrite, nitrate, DO) of catfish. The addition of probiotics in the P1 (addition of bioprisma probiotics 0,15 mL/l ,5 L of water) gave the best effect in increasing the growth of  catfish, 18,70% body protein and 8,73% body fat. The integration of biofloc with aquaponics technologies can eliminate geographical limitations and accelerate the urbanization of aquaculture.
