Rice is the primary food commodity in Indonesia. To increase the rice production, urea fertilizer has been excessively used, specifically on marginal land. However, it has no desired effect on the plantâ€™s Nitrogen uptake due to volatilization. Previous studies suggest the use of zeolite to be mixed with urea to reduce the volatilization rate. This study aimed to determine the effect of six NP-SR (Nitrogen Phosphorus Slow Release) fertilizer compositions (without NP-SR; 20.69-0; 19.7-5; 17.27-10; 15.9-15; and 18.94-20) on soil chemical properties, nitrogen efficiency, and paddy rice yield on Ultisols at three waterlogging levels (0.5 cm, 3 cm, and 5 cm). The study was an experiment arranged in a Randomized Complete Block Design (RCBD) consisting of two factors, which were waterlogging levels and NP-SR fertilizer compositions. The results showed that waterlogging treatments significantly affected soil chemical properties in the initial vegetative and harvest phases. It can be concluded that the treatment of flooding (up to 3 cm) and fertilizer (NP-SR of 15.90-15) application could significantly reduce the volatilization rate, increase the efficiency of N fertilizer, and increase rice yield.

This research explores the impact of intercropping corn and soybean, along with the combined effects of Azolla pinnata dose, the best soybean variety, and cytokinin concentration, on enhancing the physiology and agronomy of the plants. The study was conducted using 36 experimental units in a plot between soybean and corn. Various parameters were observed, including seed viability and vigor, soil analysis, nutrient content analysis of POC Azolla pinnata, temperature, air humidity, sunlight radiation, rainfall, pest infestation, diseases, and weeds. Additionally, plant height, leaf count, secondary branch count, total plant dry weight, leaf chlorophyll, leaf area ratio, leaf chlorophyll index, and stomatal conductance were measured. The data were analyzed using Djajasukanta and Sitompul-Guritno calculations, focusing on the average relative growth rate (RGR), average net assimilation rate (NAR), and root-shoot ratio (RSR). The results demonstrated that intercropping corn and soybean with the combination of Azolla pinnata dose, the best soybean variety, and cytokinin concentration had a positive impact on soybean production and quality. The Anjasmoro variety showed favorable outcomes in various parameters, such as plant height, leaf count, and branch count. Physiological leaf analysis revealed that the treatment combination with the Anjasmoro variety exhibited optimal photosynthetic rates and chlorophyll content, indicating higher photosynthesis efficiency. Moreover, the treatment with the Dega 1 variety displayed faster growth and efficient resource allocation, as evident from the high RSR value. The selection of the best soybean variety, Azolla pinnata dose, and cytokinin concentration can lead to sustainable improvements in soybean crop yield. These findings hold significant implications for agricultural management and enhancing food security.

Penelitian ini bertujuan untuk mengevaluasi metode ekstraksi minyak kedelai dari varietas unggul Anjasmoro yang ditanam dengan sistem tanam tumpangsari dan diberi perlakuan azolla serta sitokinin. Metode ekstraksi yang digunakan adalah Soxhletasi dengan pelarut etanol 96%. Proses ekstraksi melibatkan penghalusan kacang kedelai, diikuti dengan penggunaan kolom Soxhlet dan pemanasan menggunakan elektromantel. Pengamatan dilakukan terhadap laju aliran pelarut dan pengembunan selama ekstraksi berlangsung. Hasil ekstraksi kemudian melalui proses destilasi untuk mengukur massa jenisnya, dengan tahap terakhir adalah penguapan minyak hingga pelarutnya habis. Hasil penelitian menunjukkan bahwa ekstraksi minyak kedelai Anjasmoro menghasilkan hasil yang efisien, dengan kadar air yang cocok untuk proses ekstraksi. Rendemen minyak dan yield minyak menunjukkan efisiensi proses ekstraksi yang baik. Varietas Anjasmoro juga menghasilkan ampas basah dan kering, serta endapan putih. Penggunaan azolla dan sitokinin meningkatkan efisiensi produksi dan kualitas minyak. Dengan demikian, metode ekstraksi ini efisien dalam menghasilkan minyak kedelai yang signifikan dan berpotensi meningkatkan hasil pertanian secara berkelanjutan.

Penelitian ini dilakukan untuk mengevaluasi dampak konsentrasi Pupuk Organik Cair (POC) Azolla dan pilihan kultivar terhadap Nisbah Kesetaraan Lahan (NKL) pada jagung dan kedelai dalam sistem tumpangsari. Penelitian dilaksanakan di Desa Sanca, Kabupaten Indramayu, dari Juli hingga Oktober 2022. Hasil menunjukkan bahwa konsentrasi POC Azolla berpengaruh pada pertumbuhan dan hasil tanaman kedelai. Kombinasi tertentu, seperti POC Azolla dengan Dega 1, Anjasmoro, dan Grobogan, memberikan hasil tertinggi. Hasil analisis juga menunjukkan bahwa Anjasmoro dengan konsentrasi POC Azolla 400 ml/l memberikan hasil biji per tanaman, bobot 100 biji, dan bobot biji per petak tertinggi. Perlakuan P21 + Anjasmoro memiliki NKL tertinggi, menandakan keunggulan dalam meningkatkan produksi tanaman kedelai dan tumpangsari. Keseluruhan, penelitian ini menyoroti pentingnya pemilihan kultivar dan konsentrasi POC Azolla untuk meningkatkan produktivitas dan kesetaraan lahan dalam sistem tumpangsari jagung dan kedelai.

The effort to fulfill the need of rice through the improvement of dryland productivity can be viewed as a more environmentally-friendly way. This research used 36 rice genotypes in M1 generation that were grown hydrophonically under drought stress level of -0.03 MPa. The identifications were conducted based on peroxidase isozyme marker. The isozyme patterns in zymogram were binary-coded by visual scores for each genotype, based on the thickness and the number in the appearance of bands on certain migration distance. The migration distances were measured based on values of Rf. The similarity coefficients were calculated using Dice’s coefficient that were used to construct dendrogram using the UPGMA employing the SAHN from the NTSYSpc 2.02. The results showed that the most resistant genotype under drought stress was R-4, and the genetic relationships among the genotypes were divided into two main groups, aromatic and non-aromatic group, in which some genotypes experienced the reduced levels of aromatic character (R-8 and R-9) and the drought resistance character (IU-2, IU-3, IU-4, IU-5, IU-6, IU-7, and IU-8), but there were some genotypes to able to improve the resistance under drought stress (R-2, R-3, R-5, R-6, R-7, IT-4, IT-5, and IT-7). Keywords: drought resistance, gamma irradiation, peroxidase isozyme, rice, sodium azide

The aim of this research was to study the relationship between fruit drop and contents of auxin, polyamines, ACC, total sugar, and starch. Cultivars of mango used were Gadung 21 and Lalijiwo.The persisting fruit and abscising fruits were used to quantify auxin, polyamine, ACC, total sugar, and starch. The content of polyamine and ACC was determined on pericarp, auxin on seed, whereas the content of starch and total sugar was determined on mesocarp. The result of research showed that fruit drop was preceded by low content of auxin that increased the sensitivity of abscission zone to ethylene. The increased sensitivity of abscission zone to ethylene was supported by low content of polyamine and high content of ACC. The abscising fruit has high content of starch, but low in total sugar content. Key words : Mango, persisting fruit, abscising fruit, auxin, polyamine, ACC, total sugar, starch
