The objective of this study was to ascertain the impact of critical thinking skills on the learning outcomes of junior high school students, with the Self- Organized Learning Environment (SOLE) learning model serving as the experimental framework. The research methodology employed was quasi- experimental, with a research design of nonequivalent control group design. In this study, the experimental class was Grade 8 A Class, while the control class was Grade 8 C class. The SOLE learning model demonstrated a statistically significant effect on critical thinking skills and learning outcomes, as evidenced by the t-test results with a value of 0.05 < 0.000. The N-gain score for the SOLE learning model revealed that 51.5% of the learning outcomes were less effective, while 56.8% of the critical thinking skills were moderately effective. In contrast, the control class in the Discovery Learning learning model achieved 32.3% in learning outcomes and 38.2% in critical thinking skills, both of which were ineffective. The results of the research indicate that critical thinking skills and junior high school science learning outcomes are significantly influenced by the SOLE learning model.

Native lipase is still promising as an industrial biocatalyst. This study aimed to investigate the production of native local lipase using solid state fermentation (SSF) methods, immobilization the lipase by Ca-alginate entrapment, and characterization based on substrate preferences. To obtain high lipase production using SSF methods, we optimized the type of agro-wastes substrates, fermentation time, oil induction percentage and volume of preculture percentage. The optimal condition for lipase production via solid-state fermentation involved a 7% (v/v) preculture of Pseudomonas aeruginosa SB-37, utilizing palm kernel meal as the substrate, supplemented with 6% (v/w) oil induction (soybean oil:tween 80 = 75:25) at 50 °C for 24 h. This gave a lypolitic activity value of 2 U/gds (gram dry weight substrates). Since the protein profile of extracellular lipase has a few protein bands, we perform direct immobilization on crude protein supernatant. Immobilization by Ca-alginate entrapment results in loading capacity and recovery activity values of 86.84% and 148%, respectively. The immobilized lipase retained 92% activity until four batch repetition and keep 40% activity at tenth batch. The highest hydrolytic activity of immobilized lipase was 0.9 U/g gel on the pNP_8 substrates. While the highest transesterification activity was observed with acetonitrile solvent and substrates of pNP_8 and isopropanol with the activity value at 0.6 U/g gel. This present study emphasized the feasibility of producing lipase as a biocatalysts using economical agro-industrial wastes and efficient immobilization using entrapment method.

Nyamuk merupakan vektor utama penyakit seperti DBD, Chikungunya, dan Malaria, terutama mengancam anak-anak di Desa Karang Kembang, Kecamatan Babat, Kabupaten Lamongan, pada musim hujan pasca El Niño. Pengendalian nyamuk masih bergantung pada fogging yang kurang efektif dan merusak lingkungan. Program ini memperkenalkan perangkap nyamuk berbasis sinar UV (qiUT) dan biolarvasida dari limbah gadung (Dioscorea hispida) sebagai solusi praktis dan ramah lingkungan. Kader PKK diberdayakan untuk membuat qiUT dari botol bekas dan memproduksi biolarvasida melalui maserasi. Kegiatan ini meningkatkan kapasitas 35 kader PKK dalam pengendalian nyamuk, dengan monitoring mingguan dan identifikasi jenis nyamuk, seperti Culex sp. dan Aedes sp. Program ini juga meningkatkan kesadaran masyarakat dalam kegiatan monitoring jentik. Kombinasi qiUT dan biolarvasida terbukti efektif sebagai metode alternatif yang aplikatif dan ramah lingkungan untuk pengendalian nyamuk di skala rumah tangga.

Gel is a semisolid preparation that is clear, translucent containing active ingredients, can provide a cool effect on the skin and good spread of the skin. The use of gelling agent in gel formulations greatly affects the physical properties of the resulting gel preparations. HPMC is a gel forming material that is neutral and can form a clear gel and can maintain the viscosity of the resulting gel, while carbopol are easily dispersed in water and produce preparations with sufficient viscosity. The research conducted aims to determine the comparison of carbopol and HPMC in the optimal gel formula of betel leaf extract nanoparticles with Simplex Lattice Design method. The response used was pH, viscosity, spreadability, adhesion and antibacterial activity against Staphylococcus aureus. The results obtained by carbopol concentration of 80.9% and HPMC 19.1% was the optimal gel formula of betel leaf extract nanoparticle. Based on the verification, an insignificant difference was obtained between the predictions of the software and the results of the tests performed. This shows that the method used was valid or can be trusted.

Background: The lack of knowledge regarding balanced nutrition intake in adolescents resulted in suboptimal diets. Therefore, there is a need for an educational program aimed at transforming their diet following balanced nutrition guidelines. Method: The partner of this activity is class 10 RPL 2 at SMK Mahardhika Batujajar, the number of participants is 35 people, providing education on balanced nutrition through Nutristzil, an interactive web-based game. The effectiveness of this program was evaluated through pretest and posttest results. In addition, the program also includes training in website and game development, with the expectation that teachers and students studying software engineering can develop resources for nutrition education and other topics after the program’s completion. Result: The evaluation results reveal a significant difference in knowledge before and after the program, indicating a positive response from the students. Conclusion: Behavioral change can be achieved through the establishment of new habits practiced consistently for 21 days.

Industri apel di Indonesia menghadapi berbagai tantangan, salah satunya adalah hama dan penyakit tanaman. Perawatan kebun apel dari serangan hama di Desa Bulukerto tidak menghasilkan keuntungan. Hal ini mendorong pendampingan serta pengembangan solusi berkelanjutan untuk pengendalian hama apel. Sasaran dari kegiatan ini adalah masyarakat kelompok tani sebanyak 20 orang. Kegiatan ini bertujuan untuk melakukan pendampingan penyiraman pupuk cair organik berbasis arduino untuk pengendalian hama pada kebun apel di Desa Bulukerto. Sistem ini menggunakan pupuk cair alami yang aman dan ramah lingkungan. Pupuk cair memanfaatkan limbah kulit apel yang kurang dimanfaatkan masyarakat. Adapun metode pelaksanaan meliputi sosialisasi, pelatihan, pendampingan, dan monitoring. Hasil menunjukkan bahwa program ini mendapat respon positif dari masyarakat, memberikan pengetahuan baru kepada petani tentang penyiraman otomatis dapat meningkatkan penggunaan biopestisida ramah lingkungan, menghemat air melalui sistem penyiraman sehingga berpotensi meningkatkan hasil panen apel dan mengurangi kerugian.

Ngrangin Hamnlet, Sumberpasir Village, Malang Regency, is a major banana growing area that produces a lot of organic waste from banana stems. Sadly, this waste is not being used as well as it could be, even though there is a growing need for fertilizer, which is often hard to get for farming. The Purpose of this community service is to help banana farmers learn how to make compost from banana plant waste. This will help them become more self-sufficient effective in getting organic fertilizer locally. This workshop used a learning and hands on approach, including advice, practice and technical help. The activity was aimed at 26 banana farmers who belong to farmer group in Ngrangin Hamlet. The result show that the farmer understood more about recycling farm waste and had better skills in making compost. The compost was good quality, with a crumby texture, dark brown colour, and odorless. Another good thing was that banana farmer started working together to manage compost in the hamlet and they became more aware of sustainable farming methods. This activity shows that helping people locally with the right technology can be a good way to manage waste and provide the fertilizer farmers need.
