Abstract

Rice grains produced in the conventional system are a prime source of heavy metal exposure in the human body leading to various health problems. The objective of this study was to assess heavy metals concentration in soil and rice grain under the conventional rice farming system in Banyumas, Indonesia, the pollution index, and the bioaccumulation factor. There were thirty-seven samples collected based on soil type, elevation, and irrigation system. The heavy metals level in soil ranged from 2.7 to 39.92 ppm of Pb, 0.11 to 3.01 ppm of Cd, and 4.79 to 61.32 ppm of Cr. Pb and Cr accumulation levels were below the maximum permissible concentration (MPC). A different result in Cd exceeded the MPC in 56.75% of sampling sites. Rice grain showed a high accumulation in Pb (6.85 ppm) and Cr (5.73 ppm) that exceeds the maximum standard. Cd exceeded 24.32% of sampling sites with an average of 0.54 ppm. The Pollution Index (PI) was medium in Cd and low in Pb and Cr. The Bioaccumulation Factor (BAF) of heavy metals in rice was Cd>Pb>Cr with averages of 0.64, 0.53, and 0.30, respectively. A high correlation resulted in Pb and Cd in soils and rice grains. Remediation is must done to reduce the heavy metals accumulation in soils and rice grains for environmental and health safety to prevent further contamination.

Abstract

Millet is a cereal plant that’s potential for rice substitution. This plant is adaptive to be cultivated in dry land but has a tolerance limit to drought stress. Mycorrhiza and phospate (P) fertilizer treatments help plants adapt to this condition. This study aimed to determine the effects of phosphate fertilizer and mycorrhiza as well as their interaction effects on the growth and yield of foxtail millet (Setaria italica L.) under drought stress. The experiment was carried out from January to June 2020 in the experimental farm, Faculty of Agriculture, University of Jenderal Soedirman. The research was arranged in a factorial randomized complete block design consisting of two factors. The first factor was the dose of SP-36 fertilizer per polybag, namely P0 = 0 g, P1 = 37,5 kg.ha⁻¹ (25%), P2 = 75 kg.ha⁻¹ = 0.88 g/polybag (50%), and P3 = 150 kg.ha⁻¹. The second factor was the dose of mycorrhiza biofertilizer, namely M0 = 0 g.polibag⁻¹, M1 = 33.3 g. polibag⁻¹ and M2 = 66.6 g.polybag⁻¹. The treatment was replicated three times. The data observed were analyzed using the F test, continued with DMRT test at p=0.05. The results showed that SP-36 fertilizer application at half of the recommended dose (0.88 g/polybag) could increase growth variables, such as leaf area, panicle length, and seed weight. Mycorrhizae application 33.3 g/polybag could improve variables such as plant height, leaf area, panicle length, and seed weight. It also accelerated the initiation of panicle emergence compared to control.

Abstract

Strawberries have various benefits for human health so they are widely loved by the public. Serang Village, Karangreja District, Purbalingga. This village is located on the slopes of Mount Slamet with an altitude of about 650 - 1,600 m dp is one of the centers of strawberry cultivation in Central Java, but since 2016 it has experienced a decline in production due to poor quality seeds, high fertilizer prices, declining soil fertility and the existence of pests and plant diseases. The purpose of this research-based community service activity is to implement the results of the research to solve the problems that exist in the Sida Urip farmer group, provide training in making organic fertilizers and pesticides, assist in the practice of making organic fertilizers and pesticides, improve skills in maintaining strawberry plants, so that it can increase strawberry production The method used in this activity is Rural Appraisal Participation, which is the active involvement of all elements of the target audience, the stages of the activity include: Survey, socialization of activities, training, practice, demonstration plot making and evaluation. The results of the activity showed that there was an increase in the knowledge and skills of farmer groups in making compost and biological agents to support environmentally friendly strawberry cultivation. The eco-friendly strawberry demonstration plot produces 38.69 kg/bed of strawberries and conventional strawberry cultivation land produces 37.45 kg/bed. The assistance carried out by the service team also increased enthusiasm and cohesiveness among members of the Sida Urip farmer group.

Abstract

Kubis bunga merupakan komoditas sayuran yang potensial karena mengandung vitamin dan mineral. Budidaya kubis bunga perlu dikembangkan ke lahan marjinal seperti Ultisol. Pemanfaatan mikoriza-trichoderma dapat meningkatkan kesuburan ultisol. Tujuan penelitian untuk menentukan dosis mikoriza dan trichoderma dengan pengurangan pupuk anorganik terhadap pertumbuhan, hasil dan kandungan vitamin C kubis bunga di ultisol. Penelitian berupa percobaan pot yang diletakkan di lahan menggunakan rancangan acak kelompok lengkap faktorial yang diulang tiga kali. Faktor pertama adalah kombinasi mikoriza+Trichoderma yaitu 0 g + 0 g (tanpa mikoriza+trichoderma), 10 g + 10 g dan 20 g + 20 g, faktor kedua adalah pengurangan pupuk anorganik (urea, SP36 dan KCl) dari dosis rekomendasi yaitu 0%, 25% dan 50%. Data dianalisis dengan uji F dan DMRT. Hasil penelitian menunjukkan bahwa pemberian 20 g mikoriza + 20 g trichoderma tanaman-1 meningkatkan persentase infeksi mikoriza 56.7% dibandingkan dengan 10 g mikoriza + 10 g Trichoderma tanaman-1. Kombinasi terbaik dengan tanaman tertinggi diperoleh pada tanpa mikoriza-Trichoderma dengan pengurangan 25% pupuk anorganik, sedangkan pada bobot akar kering tertinggi pada 10 g mikoriza + 10 g Trichoderma dengan 50% pupuk anorganik. Kombinasi terbaik dengan hasil (curd) tertinggi diperoleh pada 20 g mikoriza + 20 g Trichoderma dengan pengurangan dosis pupuk anorganik 25%, sedangkan kandungan vitamin C tertinggi pada 20 g mikoriza + 20 g trichoderma dengan pengurangan anorganik sebesar 50%.Kata kunci: budidaya, lahan marjinal, pupuk hayati, sayuran
