Abstract

Kelompok Tani Ngudi Kaweruh merupakan salah satu kelompok tani aktif di Dusun Tegal Rejo terletak di Desa Sabrang, Kecamatan Ambulu, Kabupaten Jember. Salah satu kendala yang banyak dikeluhkan petani adalah pupuk subsidi yang terbatas dan sulit didapat. Selain itu, untuk memperoleh pupuk subsidi harus melalui prosedur yang tidak mudah. Petani akhirnya beralih menggunakan pupuk anorganik non subsidi yang dijual dengan harga tinggi. Selain itu, penggunaan pupuk dan pestisida kimia yang berlebihan akan meningkatkan biaya produksi sehingga akan menurunkan keuntungan. Oleh karena itu, diperlukan solusi alternatif pemupukan yang aman dan bekelanjutan. Berdasarkan permasalahan Mitra, alternatif solusi yaitu program penerapan kompos blotong sebagai substitusi pupuk anorganik di kelompok tani tersebut. Program dilaksanakan sejak bulan Juli – September 2024. Tahapan kegiatan meliputi survey dan sarasehan, sosialisasi kompos blotong, diskusi, dan pendampingan. Hasil kegiatan menjelaskan bahwa kelompok tani memiliki cara pandang lain terhadap pupuk anorganik, keberlanjutan agroekosistem, dan ekonomi sosial

Abstract

Introduction: Melon (Cucumis melo L.) is one of the horticultural plants of the fruit type which is included in the gourd tribe or Cucurbitaceae family. The problem of melon cultivation in the field is that it requires intensive maintenance, is susceptible to pests and diseases, uses less efficient nutrients, is sensitive to weeds, and has less controlled growth. The above problems can be overcome by hydroponic techniques. In hydroponic techniques, environmental resources are easier to control and the results obtained are more satisfying compared to conventional cultivation, especially in open fields. Amino acids are proteins that have been broken down through the metabolic process into small molecules. In addition to humans, plants also need amino acids to increase overall yields and quality. Methods: This study aims to determine the effect of providing the best Amino Plant concentration for the growth and production of melon plants. This study was conducted in June - October 2022 at the Smart Green House (SGH) of Jember State Polytechnic. The experimental design used was a Completely Randomized Design (CRD) consisting of one factor, namely the concentration of Amino Acid with 3 levels, namely P1 (4 mg/L), P2 (8 mg/L), and P3 (12 mg/L). Results: The results of the study showed that the administration of Amino Acids at a dose of 2 g/L gave results that were not significantly different (ns) in all parameters and showed that there was no effective concentration for melon growth and production in all parameters.Conclusion: Based on the results of this research, it is recommended to carry out further research by applying Amino Plant according to the guidelines on the packaging. It is necessary to calibrate the drip irrigation or fertigation system so that the nutrient flow is uniform.

Abstract

The cotton plant is a fiber plant that is commonly used as a raw material for textiles, beauty, and health products. To increase cotton production, the development of superior varieties using plant breeding methods in cross-analysis is necessary. The cross-analysis method is used to determine the agronomic traits that affect cotton production, by selecting yield through several other characteristics related to yield. The aim of this study was to identify which agronomic characters can be used as selection criteria to increase cotton production using cross-analysis. The research was conducted at Politeknik Negeri Jember, and included 12 independent variables and one response variable, namely cotton production. The method used in this study was to perform correlation analysis, cross-analysis, calculate direct and residual contributions, and select agronomic characters that can be used as selection criteria. The results showed that the number of fruit characters had the highest correlation with cotton production (RX9Y = 0.835). Cross-analysis was carried out, and the highest direct effect was found between the number of fruit characters and cotton production (PX9Y = 0.971). The highest direct contribution was found in the character of the number of fruit, which had a total contribution of 98.321% and residue of 1.679%. Therefore, the agronomic character that can be used as a direct selection criterion is the number of fruits.

Abstract

Fusarium oxysporum f.sp. cubense (Foc) is an important pathogenic fungus that causes Panama disease in banana. One approach to overcome this problem is to utilize secondary metabolites from Trichoderma sp. This research was conducted to determine the effect of administering secondary metabolites from Trichoderma sp. against pathogen Foc. These metabolites were applied at concentrations of 10%, 20%, and 30%, 40% alongside a fungicide active ingredient of phosphoric acid 400 SL. This study used a Completely Randomized Design with 6 treatments 4 repetition. The parameters observed included colony diameter and percentage of inhibitory. The extraction of secondary metabolite isolation could be obtained as much as 500 ml with reddish brown, thick and odorless characteristics. Secondary metabolites showed a significant effect in inhibiting the growth of the pathogen Foc. The results showed the 10% concentration proved to be the most effective to inhibit pathogen Foc, resulting in the smallest colony diameter of 0.58 cm and an in vitro inhibition rate of 90.73%.

Abstract

Indonesia's orange production in 2014 increased from 1.78 million tonnes to 2.16 million tonnes. In 2016 orange production decreased by 2,212 tons. The decline in orange production was caused by weeds. Weeds cause a reduction in crop yields of up to 61%. The research aims to identify the types of weeds and the secondary metabolic potential of dominant weeds in citrus plants. The research results showed 10 families, 23 species and 400 individual weeds. The weed that has the highest SDR value is the grass type Tridax procumbens with a Summed Dominance Ratio (SDR) value of 7.28%. Phytotoxicity in Tridax procumbens leaf plants is P4 with a concentration of 80g/l of 45.33. Wet weight and dry weight affect the P4 concentration with a concentration of 80g/l that most inhibits the growth of Tridax procumbens. Kirinyuh plants contain flavonoids of 250.24 mg/L, phenolics of 265.75 mg/L, and tannins of 242.38 mg/L. The high levels of phenolic compounds in kirinyuh weed have the potential to be used as a bioherbicide.
