The coastal region is a dynamic area as a transition between the land and the sea. The ecological function of the coastal area is affected mainly by the structure and composition of vegetation factors. This study aims to analyze the vegetation stratification of terrestrial to marine ecosystems in the coastal area of Semarang City, Central Java Indonesia as an effort to manage a sustainable ecosystem. A striped path combined with nested plots were applied in this research. The plots were placed by systematic purposive sampling based on the homogeneity of vegetation found along with the topographic conditions of the research location. Analysis of qualitative data used by way of inventorying plants and identifying plants based on morphological characteristics that can be observed. Data analysis was performed based on the results of an inventory of the structure and composition of vegetation obtained including the index of diversity, evenness, and species richness. The results of plant identification found in the three locations recorded 51 plant species consisting of 29 families. The different types of vegetation in Taman Lele, Tapak, and Tirang Beach affect the diversity, richness, and evenness index of vegetation in all three locations. Therefore, it can be concluded that different environmental factors contribute to the vegetation stratification from the land to the sea. This is the first report on the Semarang coastal area vegetation stratification. The results can have a positive impact on the coastal area conservation strategy for sustainable management, as well as to be a media for environmental education purpose.

Daya simpan cumi-cumi dipengaruhi oleh aktivitas enzim katepsin yang menyebabkan kemunduran mutu cumi-cumi pada hari ke tiga setelah fase post rigor. Aktivitas inhibitor katepsin alami dari ikan patin berpotensi menghambat kemunduran mutu ikan jenis lain. Penelitian ini bertujuan untuk menganalisis senyawa inhibitor enzim katepsin dari kulit ikan patin terhadap kemunduran mutu cumi-cumi. Penelitian didesain dengan rancangan acak dengan pola dua faktorial. Faktor pertama adalah konsentrasi inhibitor enzim katepsin yang diekstrak dari kulit ikan patin, dengan empat variasi yaitu 1:0; 1:1; 2:3; dan 3:2. Faktor kedua adalah lama rendaman/inkubasi cumi-cumi pada fase post rigor selama 3, 7, dan 9 hari dalam ekstrak inhibitor. Setelah direndam, aktivitas enzim katepsin pada cumi-cumi diukur dengan metode spektrofotometri. Setelah didapatkan absorbansi maka aktivitas enzim dan persentase penghambatannya dihitung. Hasil uji Two Way Annova menunjukan bahwa konsentrasi berbeda nyata dengan peresentase penghambatan sedangkan lama penyimpanan tidak berbeda nyata dengan taraf kepercayaan 0,05. Konsentrasi kemudian diuji lanjut dengan Duncan dan konsentrasi yang paling efektif untuk menghambat aktivitas enzim adalah konsentrasi 3:2 dengan persentase penghambatan 57%.Â

Pakchoy is a leafy vegetable that is great demand by Indonesians. The increase in population has had a major impact on agricultural land, which has encouraged an urban farming system, using polybags for crop production. The use of soil media in polybags often experiences compaction and lack of nutrients, so it is necessary to modify the composition of the planting media and put additional fertilization. This research was conducted to evaluate the response of pakchoy to local microorganisms based on rice waste and to determine the best composition of growing medium for pakchoy plants. This study used a completely randomized design (CRD) with 2 factors. The first factor was the local microorganism (LMO) doses of rice waste consisted of 4 levels, namely 0 ml, 500 ml, 1000 ml, and 1500 ml per plant. The second factor was the composition of the planting medium (Soil : Sand: Cow Manure) at 4 levels, namely Soil 100%, 1:1:1, 1:1:2, 1:1:3. Data were statistically analyzed with ANOVA at 5% level. Mean separation was tested further with Duncan Multiple Range Test. The results showed that the LMO 0 ml and 500 ml performed higher effects on plant height, number of leaves, plant fresh and dry weight, root fresh and dry weight, and root length compared to the application LMO at 1000 ml and 1500 ml. The highest plant fresh weight was 193.1 g at 0 ml LMO, followed by 160.35 g at 500 ml LMO. The composition of the planting medium 1:1:1 and 1:1:2 resulted in a higher number of leaves, plant dry weight, and root weight than other treatments. Incorporating a high portion of manure into the pakchoy planting medium was not beneficial. All growth variables and yield were higher compared to the control medium (soil 100%). Key Words: pakchoy, local microorganism, planting media

Penelitian ini bertujuan untuk menganalisis kebijakan pengembalian sistem penjurusan di jenjang Sekolah Menengah Atas (SMA) di Indonesia dengan pendekatan berpikir sistem (systems thinking), khususnya menggunakan Causal Loop Diagrams (CLD) dan simulasi sistemik. Penelitian ini menggunakan metode scoping review terhadap 35 literatur relevan, serta pemodelan sistem berbasis perangkat lunak Vensim PLE untuk memetakan hubungan kausal antar variabel kunci dalam sistem pendidikan. Hasil analisis mengungkap adanya dua pola feedback utama: reinforcing loop yang menunjukkan peningkatan motivasi belajar dan prestasi akademik akibat eksplorasi minat yang lebih bebas, serta balancing loop yang menggambarkan dampak negatif beban kurikulum terhadap kebebasan eksplorasi siswa. Temuan ini menunjukkan bahwa kebijakan penjurusan yang tidak mempertimbangkan kompleksitas sistem pendidikan dapat memperkuat ketimpangan dan menghambat potensi siswa. Sebaliknya, jika dirancang secara sistemik dan adaptif, kebijakan ini dapat mendorong pembelajaran yang lebih relevan dan berkelanjutan. Kontribusi penelitian ini terletak pada penyediaan kerangka konseptual dan visual berbasis CLD yang dapat digunakan oleh pengambil kebijakan untuk mengantisipasi dampak jangka panjang dan merancang kebijakan pendidikan yang lebih responsif terhadap kebutuhan peserta didik. Studi ini memperkuat pentingnya pemanfaatan berpikir sistem dalam merumuskan kebijakan pendidikan di tengah tantangan kompleksitas sosial dan ketimpangan sumber daya.

A field trial was conducted to determine the efficiency of AMF inoculation for enhancing growth and yield performance of maize, root colonization, soil available P, and P uptake in Ultisols amended with different P dosages. This experiment was conducted in a 3 x 3 factorial scheme under complete randomized design with three AMF inoculation methods and three different P levels (0, 60, and 120 kg P2O5 ha-1) in five replications. Data were collected on plant growth, yield parameters, soil available P, P uptake, and root colonization. Results showed that inoculation via seed coating at 60 kg P2O5 ha-1 gave a significant (p<0.05) increase in growth traits (average of 25%), biomass production, grain yield (average of 30%), soil P availability, P uptake, and root colonization. Inoculation via seed coating combined with 60 produced the same values of all the tested parameters with and seed coating inoculation and soil inoculation at120 kg P2O5 ha-1. Thus, seed coating was as effective tool as soil inoculation for AMF delivery and capable of reducing 50% of P fertilizer use. For these reasons, co-application of P fertilizer and AMF inoculation via seed coating could be practiced to improve corn yields on poor Ultisols.

The impact of Azolla compost (AC) substitution for synthetic N fertilizer (NF) on nitrate leaf content and agronomic performances of green onion in Ultisols have not been well understood. Therefore, this study aimed to assess the effects of equal replacing NF with AC on growth, yield, and nitrate accumulation in the green onion leaf. The polybag trial was performed in June 2020 on the crop research farm of the Agriculture Faculty in a completely randomized design with six treatments in five replications. Green onion was subjected to five 92 kg ha−1 N equal combinations of NF and AC, i.e., NF100 (100% NF+0% AC), NF75 +AC25 (75% NF+25% AC), NF50 +AC50 (50% NF+50% AC), NF25 +AC75 (25% NF+75% AC), and NF0 +AC100 (0% NF+100 % AC) and no NF and AC as a control. Results demonstrated that NF+AC treatments significantly improved plant height, leaf number, tiller number, stem diameter, and plant fresh weight. Treatment of NF25+AC75 resulted in similar responses to the recommended dose of N fertilizer, as evidenced by plant height, number of green leaves, root fresh weight, shoot dry weight, tiller numbers per hill, stem diameter, shoot fresh weight, and plant fresh weight. Lower leaf nitrate contents occurred under increased substitution of NF with AC. Thus, partial substitution of NF with AC could be a sustainable option for improving growth and yield while reducing nitrate accumulation in the leaf of green onion in Ultisols.

This study aims to systematically review the literature on the development of critical thinking and social awareness through contextual and transformative learning approaches. The urgency of this study arises from the increasing complexity of global social and environmental challenges, which demand that education go beyond academic achievement to include the formation of reflective, empathetic, and empowered learners. The research employs a Systematic Literature Review (SLR) method based on the PRISMA 2020 protocol. Data were collected from 13 empirical research articles published between 2010 and 2025 that met the inclusion criteria. Data analysis was conducted using thematic synthesis to identify patterns and key findings across the studies. The results indicate that project-based learning, critical reflection, the integration of local wisdom, and dialogical pedagogy are consistently effective in enhancing students' critical thinking and social awareness. Transformative learning that emphasizes multicultural values, social justice, and active participation also proves to foster empathy, tolerance, and civic responsibility. In conclusion, contemporary education must shift from a knowledge transmission model toward a more humanistic, participatory, and contextual approach. This study recommends strengthening teacher capacity, implementing adaptive curriculum design, and encouraging institutional innovation as key success factors in realizing effective transformative contextual learning.
