This study aims to determine the most appropriate concentration of AB mix nutrients for the growth and production of three varieties of mustard greens, and to obtain the effect of different concentrations on the growth and production of three varieties of mustard greens (Brassica Juncea L.) hydroponic NFT system. This research was conducted at the Greenhouse Jl. BaturradenKecamatanSumbersari, Jember Regency, East Java from December 1 2020 to January 4 2021. The research design used was a two-factor factorial Completely Randomized Design (CRD) with 5 replications. The first factor is the concentration of AB mix nutrients (N) consisting of two treatment levels, N1 800 - 1200 ppm and N2 1000 - 1400 ppm. The second factor is the mustard variety (V) which consists of three mustard varieties, Pakcoy Sawi (V1), Caisim Sawi (V2) and Samhong Jade Sawi (V3). The data obtained was then analyzed with the F test using SPSS 24 for Windows software at the 0.05 level. The results showed that the AB mix nutrient concentration (1000-1400) ppm gave the best response to the parameters of root length and chlorophyll content, while the concentration (800-1000) ppm responded best to the parameters of plant height, number of leaves, root weight and fresh weight. The samhong jade mustard variety provided higher growth and production than pakcoy mustard greens in the observation parameters of plant height, number of leaves, root length, chlorophyll content and root weight. The best interaction between the nutrient concentrations of the AB mix mustard variety is the concentration (1000-1400) ppm with the Samhong jade variety (N2V3) on all observation parameters.

Cucumber is a farming commodity which is relatively easy to maintain, inexpensive and short-lived. The prospect of cultivating cucumber plants is very good because cucumbers are much loved by the community. The nutritional value of cucumber is quite good because this fruit vegetable is a source of minerals and vitamins. As cucumber production increases, the development of cucumber plants also often experiences obstacles, especially in terms of soil physical and chemical properties. Continuous application of chemical fertilizers with increasing doses every year can cause the soil to become hard and disrupt the balance of soil nutrients. This research was carried out to reduce the excessive use of chemical fertilizers and as an effort to save money. One of the efforts is by using PSB. This research was carried out in Suka Makmur Hamlet, Ajung District, Jember Regency, East Java from 6 December to 27 January 2022. This study used a Randomized Block Design (RBD) method with 6 treatments and 4 replications. The treatments used were: Control (P0); 5 ml/L PSB (P1); 5 ml/L of PSB and 2g of NPKCaMg (16:16:16:6:0.5) (P2); 5 ml/L of PSB and 2g of NPKCaMg (20:4:4:18:1:1) (P3); 5 ml/L of PSB and 2g of NPKSCaMg (17:12:12:6:4:2) (P4); 5 ml/L of PSB and 2g of NPKSCaMg (20:30:23:2:3:2) (P5). The results showed that the use of photosynthetic bacteria was not able to meet the nutrient requirements for the growth and productivity of cucumber plants. Application of photosynthetic bacteria (5 ml/L) and chemical fertilizers (2g NPKSCaMg (20:4:4:18:1:1)) with a high N content had significantly different effects on fruit number and fruit weight per plant.

Integrasi Nilai Moderasi Beragama dalam Pendidikan Agama Islam untuk Pengelolaan Lahan Pertanian Berkelanjutan

Marfuah Marfuah — 2024-07-28

Penelitian ini bertujuan untuk mengintegrasikan nilai-nilai moderasi beragama, seperti keseimbangan (tawazun), keadilan (adil), tanggung jawab (mas’uliyyah), dan harmoni sosial, dalam pendidikan agama Islam untuk mendukung pengelolaan lahan pertanian berkelanjutan. Penelitian dilakukan dengan pendekatan kualitatif-deskriptif pada komunitas petani dan lembaga pendidikan di wilayah pedesaan. Data dikumpulkan melalui wawancara mendalam, observasi, dan dokumentasi, kemudian dianalisis menggunakan metode triangulasi. Hasil penelitian menunjukkan bahwa pengajaran nilai-nilai agama melalui ayat-ayat Al-Qur’an, kisah-kisah Nabi, dan kegiatan ekstrakurikuler berbasis lingkungan mulai diterapkan, meskipun masih sporadis dan tergantung pada inisiatif guru. Di sisi lain, praktik pertanian berkelanjutan seperti penggunaan pupuk organik dan rotasi tanaman telah diterapkan petani, tetapi lebih didorong oleh alasan ekonomis daripada religius. Hambatan utama mencakup keterbatasan pemahaman guru tentang pertanian berkelanjutan dan kurangnya kurikulum tematik. Model pembelajaran berbasis moderasi beragama yang melibatkan pendekatan kontekstual, kolaborasi lintas disiplin, dan kegiatan lapangan diusulkan untuk meningkatkan kesadaran ekologis dan tanggung jawab moral. Penelitian ini menekankan pentingnya pendidikan agama dalam menciptakan harmoni sosial dan keberlanjutan lingkungan.
