The decrease of soybean productivity was caused by low quality of seed. To improve the quality of seed, soybean seed were coated with Trichoderma sp. and adding bokashi organic fertilizer. This research aimed at finding the best dose combination of Trichoderma sp. and bokashi fertilizer to improve the quality of soybeans. The research was conducted in the experiment field and Laboratory of Seed Technology at Padjadjaran University in April - August 2017. The experimental design in this research was Randomized Block Design (RBD). The treatments were the combination of four dose values of coating the seed by Trichoderma sp. (0g/100 seeds, 1g/100 seeds, 2g/100 seeds, and 3g/100 seeds) and three dose of bokashi (0g/polybag, 300g/polybag, and 600g/polybag) and each treatment was replicated three times. The experiment result showed that all treatments on soybean seeds did not affect the germination percentange, vigor index, and conductivity value, but affected the seed quantityof 600g/polybag of bokashi and without seed coating with Trichoderma sp. on 100 seed mass and seed weight per plant.

Bambara groundnut has the potential to be an alternative food source of protein and carbohydrates. However, the quality of the seeds is not guaranteed, which can affect plant growth. The experiment aimed to determine the growth response of Bambara groundnut to the application of nitrogen fixation bacteria (Rhizobium sp.) and phosphate solubilizing bacteria (Pseudomonas sp.) integrated into matriconditioning and nitrogen-phosphate (NP) fertilizer. The experiment was conducted in Situraja-District, Sumedang Regency, West Java, Indonesia from November 2020 to April 2021. The experiment was arranged in a split-plot randomized complete block design replicated three times. The main plot was NP fertilizer level (0, 50, and 100% of recommended dose), and the sub-plot was seed invigoration (untreated, matriconditioning + Rhizobium KPB2 + Pseudomonas BPF9, and matriconditioning + Rhizobium KPB5 + Pseudomonas BPF9). Corncob biochar was used as the carrier in matriconditioning. The seed invigoration treatments using matriconditioning + Pseudomonas BPF9 + Rhizobium either KPB2 or KPB5 isolate significantly improved the plant growth (field emergence, plant height, leaf number, canopy diameter, and leaf chlorophyll content). Furthermore, when these invigoration treatments were accompanied by chicken manure 2 t.ha-1 significantly increased the leaf number without adding NP fertilizer.

Seed deterioration during storage significantly reduces the viability and productivity of pak choi (Brassica rapa L.). This study aimed to evaluate the efficacy of various synthetic and bio-organic invigoration agents combined with different soaking durations to restore the physiological quality of aged seeds (initial germination of 31%). The experiment was arranged in a factorial split-plot design. The main plots consisted of seven invigorating solvents: water (S1), shallot extract 50% (S2), mung bean sprout extract 5% (S3), bamboo shoot extract (S4), KNO₃ 1% (S5), GA₃ 100 ppm (S6), and PEG 6000 10% (S7). The sub-plots were three soaking durations: 15 (V1), 30 (V2), and 60 minutes (V3). The results indicated that a 30-minute soaking duration (V2) provided the optimal physiological window for metabolic repair without compromising desiccation tolerance. 10% PEG 6000 and 50% shallot extract emerged as the superior activators, consistently yielding the highest germination rates (up to 95.11%) and vigor indices (97.33%). While 10% PEG 6000 optimized post-emergence biomass, 50% shallot extract acted as a potent biostimulant due to its endogenous phytohormones. Furthermore, Radicle Emergence (RE) testing at 22 hours was identified as the most accurate diagnostic tool for predicting final germination capacity, particularly for the 30-minute treatment (R2 = 0.9943). Conversely, bamboo shoot extract (S4) exhibited a strong inhibitory effect, likely due to allelopathic phenolic compounds, and is not recommended for invigoration. In conclusion, hydropriming or shallot extract treatment for 30 minutes offers a practical and effective strategy for rehabilitating aged pak choi seeds.

Dinamika cuaca yang tidak menentu menjadi faktor utama yang mempengaruhi variabilitas produksi padi di Jawa Barat dan menuntut penerapan teknologi prediksi yang akurat untuk mendukung pengelolaan produksi pertanian secara efisien dan adaptif. Penelitian ini bertujuan mengembangkan sistem prediksi produksi padi berbasis integrasi data agroklimat menggunakan algoritma ensemble machine learning, yaitu Random Forest (RF) dan Extreme Gradient Boosting (XGBoost). Data yang digunakan meliputi variabel agroklimat berupa curah hujan, suhu udara, kelembapan, dan kecepatan angin serta data historis produksi padi di Provinsi Jawa Barat periode 2018–2024. Pengembangan sistem dilakukan melalui tahapan pra-pemrosesan data, transformasi fitur, pelatihan model, dan validasi menggunakan skema 10-fold cross-validation untuk menjamin stabilitas dan reliabilitas model. Kinerja model dievaluasi menggunakan koefisien determinasi (R²), Mean Absolute Error (MAE), dan Root Mean Square Error (RMSE). Hasil penelitian menunjukkan bahwa algoritma Random Forest memberikan performa terbaik dengan nilai R² sebesar 0,9928, MAE sebesar 16.608,92, dan RMSE sebesar 24.796,55. Variabel luas lahan, curah hujan, suhu, dan kelembapan teridentifikasi sebagai faktor utama yang memengaruhi produksi padi. Sistem yang dikembangkan berpotensi diimplementasikan sebagai teknologi pendukung prediksi produksi padi dengan memanfaatkan data agroklimat sebagai variabel prediktor, sehingga dapat mendukung pengambilan keputusan dalam pengelolaan produksi tanaman dan penerapan pertanian presisi berbasis data guna meningkatkan efisiensi serta ketahanan sistem produksi padi.
