Abstract

Pemupukan urea di petani umumnya dilakukan dengan dosis yang lebih tinggi dari standar pemerintah. Penggunaan pupuk urea berlebih dapat menurunkan produksi, kualitas tanaman, serta pencemaran lingkungan. Tujuan percobaan ini adalah melihat respon pertumbuhan, hasil dan kualitas padi sawah pada media N rendah. Rancangan percobaan menggunakan rancangan acak kelompok faktorial, dosis pupuk urea (0%, 40%, dan 100% 250 kg ha-1) dan varietas padi (Way Apo Buru dan Inpari 33). Parameter yang diamati adalah tinggi tanaman (cm), jumlah anakan, jumlah daun, chlorophyl fluorescence (unit), gabah isi (%), jumlah malai, kandungan protein terlarut (mg g-1), vitamin C (mg g-1), dan gula reduksi (mg g-1). Hasil penelitian menunjukkan bahwa reduksi pupuk urea 40% menghasilkan jumlah anakan yang sama tinggi dengan dosis standar (250 kg ha-1). Pemupukan urea dosis standar menghasilkan kandungan vitamin C, nilai chlorophyl fluorescence dan jumlah malai yang tertinggi. Inpari 33 menghasilkan karakter tinggi dan persentase gabah isi yang lebih baik sementara Way Apo Buru menghasilkan jumlah daun yang lebih tinggi. Reduksi 40% dosis urea pada Inpari 33 menghasilkan kandungan protein terlarut tertinggi. Inpari 33 menghasilkan gula reduksi terendah sehingga dapat digunakan sebagai pangan alternatif bagi penderita diabetes. Kata kunci: gula reduksi, kandungan klorofil, protein terlarut, vitamin C

Abstract

In the daily life of Indonesian people, it is inseparable from the problem of waste produced by human life which can cause environmental pollution. The average population in Indonesia has not properly processed the waste produced, especially in Jubung Village, Sukorambi District, Jember Regency. Usually, residents dispose of waste by burning it or not processing it. This causes serious problems such as unpleasant and disturbing odors, besides it will trigger the growth of microorganisms that cause disease. One effort to deal with this problem is to conduct training and processing of household waste by converting household waste or waste into organic fertilizer that can be used as a source of nutrition for plants. Training in making organic fertilizers from agricultural waste in the form of kitchen waste (vegetables) was chosen in this activity because most of the population in Jubung Village works as farmers. The activity was carried out in 3 stages, namely socialization, counseling, and practice of making organic fertilizers. The results obtained from this community service activity were that farmers can directly practice how to process household waste by converting it into useful organic fertilizers. This training was very useful for increasing knowledge and skills as well as creativity in processing household waste into organic fertilizers.

Abstract

Elevated osmotic pressure in the root zone under saline conditions acts as primary constraint to crop production by disrupting essential physiological growth process. One effective strategy for soil saline management involves the use of mycorrhizal inoculants. Delivering these microbes via seed coating is a streamlined, economical, and accurate approach that optimizes plant performance under diverse stress condition. This study aimed to evaluate the effect of mycorrhizal seed coating on the growth and yield of edamame under saline conditions. This research was arranged in a randomized complete block design with two factors, consisting of mycorrhizal seed coating (0 and 12 g mg-1) and planting media (soil, saline soil, soil + saline soil (1:1)). There were six treatment combinations, and each treatment was replicated four times, resulting in a total of 24 experimental units. The observed variables include plant height, root volume, number of pods per plant, weight of pod per fruit, number of seeds per plant, and weight of 100 seeds. The result showed that mycorrhizal seed coating had potential to improve edamame root development and optimize phosphorus uptake. While vegetative height remained unaffected, the treatment substantially improved yield components, including number of pods, seed weight, and overall seed weight. The efficacy of colonization is contingent upon soil pH and phosphorus availability, highlighting the importance of site-specific conditions. Consequently, mycorrhizal seed coating represents a practical and cost-effective strategy for improving edamame performance, offering a viable solution for enhancing crop resilience and yield in nutrient-deficient or saline environments.
