Abstract

Tembakau (Nicotiana tabacum L.) memiliki nilai ekonomi tinggi. Untuk memperoleh tembakau yang berkualitas maka media tanam dan dosis pupuk harus diperhatikan dengan baik. Permasalahan produktivitas tembakau ialah belum ada perpadudan yang tepat antara jenis media tanam lain dan pemberian pupuk N. Hal ini penting untuk pertumbuhan dan hasil tanaman tembakau. Studi ini bertujuan mencari kombinasi media tanam yang tepat antara tanah, pasir, serta kompos dan pemberian dosis pupuk urea serta pupuk ZA agar memberikan asupan unsur hara N. Studi ini dilakukan di Bondowoso, Jawa Timur yang dimulai pada November 2023 sampai Maret 2024. Percobaan dilakukan secara faktorial dengan menggunakan pola dasar RAL. Faktor pertama adalah macam media tanam yaitu (M1): tanah, (M2): tanah + pasir, (M3): tanah + kompos + pasir. Faktor kedua adalah jenis pupuk yaitu (P1): pupuk urea, (P2): pupuk ZA. Variabel yang diamati adalah tinggi tanaman, diameter batang, jumlah daun, luas daun, berat daun segar, volume akar dan berat daun kering. Data dianalisis memakai analisis ragam jika ada perbedaan nyata diantara perlakuan maka dilakukan uji lanjutan memakai uji jarak berganda Duncan taraf 5%. Hasil studi menunjukkan interaksi pengaruh media tanam dan jenis pupuk N berpengaruh tidak nyata pada seluruh variabel. Penggunaan berbagai media tanam berpengaruh sangat nyata pada seluruh variabel.  Perlakuan terbaik yaitu kombinasi media tanam tanah pasir dan kompos (M3). Penggunaan berbagai jenis pupuk N berpengaruh tidak nyata pada semua variabel kecuali volume akar.

Abstract

Vanilla (Vanilla planifolia Andrews.) is one of the plantation crops that has a high selling price, namely wet vanilla IDR 200,000-300,000/kg, regular quality dry vanilla around 1-3 million/kg, and export quality reaching 5-7 million/kg. The opportunity for farmers to develop vanilla commodities in Indonesia is very large, but limited planting materials still hamper it. In-vitro propagation is one technique that can be used to overcome the problem of vanilla propagation in Indonesia. This research aimed to determine the interaction of BAP and coconut water on the growth of vanilla nodal explants in vitro. The method used in this research was a factorial Completely Randomized Design (CRD) with a combination of Benzyl Amino Purine (BAP) and coconut water. The BAP concentration consists of 0 mg/L, 1 mg/L, and 2 mg/L. Coconut water has 0%, 15%, and 30% levels. Data were analyzed using ANOVA and further tested with the DMRT test at a confidence level of 95%. The results showed an interaction between BAP and coconut water on the growth of vanilla explants. The combination treatment of 1 mg/L BAP + 15% coconut water showed the best results with the fastest response time of 8.76+1.53 DAP, average shoot length 2.84±0.70 cm/explant and average root length 0.75±0.07 cm/explant.

Abstract

Kopi robusta (Coffea Robusta) termasuk salah satu jenis kopi yang ada di Indonesia dan lebih banyak diproduksi oleh petani di Indonesia dibandingkan kopi arabika. Produktivitas kopi rakyat di wilayah Kabupaten Jember tahun 2018 memiliki hasil yang lebih rendah yaitu sebesar 0,56 ton/ha dibandingkan produkstivitas Perkebunan Negara 0,64 ton/ha dan Perkebunan Swasta sebesar 0,75 ton/ha. Kondisi ini dipengaruhi oleh salah satu tahapan budidaya yaitu pemupukan. Petani kopi rakyat tidak melakukan pemupukan yang sesuai dikarenakan minimnya pengetahuan petani tentang pemupukan dan faktor biaya. Maka perlu dilakukan acuan dalam menentukan kebutuhan pupuk dalam setiap lokasi kebun kopi, karena setiap lokasi kebun memiliki rekomendasi pemupukan yang berbeda. Tujuan dari penelitian ini untuk mengetahui kandungan unsur hara N, P, dan K yang terbawa buah kopi robusta dan untuk mengetahui perbedaan kandungan unsur hara N, P, dan K di lima lokasi kebun kopi yang berbeda. sehingga dapat merekomendasikan metode pemupukan yang mudah dipahami oleh petani kopi rakyat. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan lima perlakuan. Perlakuan yang digunakan yaitu perbedaan lokasi yang terdiri dari 5 lokasi kebun (K) yaitu K1, K2, K3, K4, dan K5. Hasilnya terdapat perbedaan jumlah unsur hara N, P dan K yang terbawa oleh hasil panen buah kopi robusta pada kelima kebun kopi rakyat di Desa Klungkung, Kecamatan Sukorambi kabupaten Jember.

Abstract

Corn (Zea mays) is a vital staple crop and the second-largest agricultural commodity in Indonesia. However, productivity remains suboptimal, often due to nutrient imbalances, particularly in phosphate-rich soils where availability to plants is limited. This study aimed to assess the effects of reducing phosphate fertilizer by 50% in combination with bioagents Trichoderma harzianum, Metarhizium anisopliae, and arbuscular mycorrhizal fungi on key agronomic traits of corn. A randomized block design was employed to measure parameters including root volume, root-to-shoot ratio, leaf width, and seed sphericity. Results showed that applying 50% phosphate fertilizer alone yielded the highest root volume (70.00±18.19 mL) and root-to-shoot ratio (0.50±0.32), suggesting improved root development. In contrast, treatment with Metarhizium produced the widest leaves (10.14±0.30 cm) but showed the lowest values for root volume and root-to-shoot ratio. These findings highlight the potential of combining moderate phosphate input with beneficial bioagents to improve corn performance in marginal soils. The approach offers a cost-effective and environmentally sustainable alternative for managing nutrient imbalances. Further studies on long-term effects and economic feasibility are recommended to support wider adoption of these practices in sustainable agriculture.

Abstract

The coffee plant (Coffea sp.) is one of the plantation commodity crops that has been developed since the Dutch colonial era. The productivity of Arabica coffee from people's fields is equal to 0.48 tons/ha while the company's Arabica coffee plantations 0.71 tons/ha. Low productivity is one of them caused by fertilization that is not in accordance with the needs of coffee plants. So, it is necessary to know the nutrient content of N, P and K in each plantation. The content of N, P and K nutrients can be determined through the development of fertilization methods based on the loss of N, P and K nutrients carried by the harvested coffee cherries. The aim of this research is to find out of N, P and K nutrients are carried by Arabica coffee berries. The treatment was carried out at 5 different coffee fields locations and an analysis of the N, P, and K nutrient content of the harvested coffee cherries was carried out. The results showed that the nutrients N, P, and K carried by the coffee cherries were different in each plantation. Soil Analysis results on pH (bit acid) and Total Nutrient Content N (low), P (moderate – very high), and K  (low) in the soil of each field. The variables for observing the weight of sun-dried coffee beans and skins and the weight of oven-dried coffee beans and skins were significantly different in each plantation. Conclusions from this research, a). The total N, P, and K contained in 1 kg of fresh coffee fruit is 24.71 g N; 8.66 g P and 39.08 g K. b). The total N, P, and K contained in 1 kg of dry coffee beans is 74.3 g N; 26.1 g P and 117.5 ​​g K.

Abstract

Coffee is one of the important plantation commodities that plays a significant role in the Indonesian economy. Gold Robusta coffee is a potential genotype currently being developed in Jember, particularly by the University of Jember, as an alternative to the common practice of using seedling cuttings with unidentified genetic origins. This study aimed to determine the optimal nitrogen (urea) dosage containing 46% N and its growth response on immature (TBM) Gold Robusta coffee plants. The research was conducted at the Experimental Field in Darsono Village, Arjasa District, Jember Regency, from May to December 2024. The experimental design used a Completely Randomized Design (CRD) with a single factor, consisting of three levels of urea fertilizer doses, namely 15 g, 30 g, and 45 g/plant, each replicated nine times. Observed variables included plant height, number of leaves, stem diameter, number and length of productive branches, leaf area, and chlorophyll content. Data were analyzed using ANOVA, and significant differences were further tested with Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that urea application significantly affected the growth of immature Gold Robusta coffee. A dose of 45 g/plant produced the best growth performance with an average plant height of 112.78 cm, 21.44 leaves, leaf area of 163.56 cm², and productive branch length of 47 cm. Therefore, urea application at 45 g/plant can be recommended as a fertilizer guideline during the immature phase of Gold Robusta coffee.

Abstract

Vegetative propagation by cut-grafting has the advantage of being able to obtain seeds that inherit two superior traits from two scion clones in a relatively short time. The purpose of this research is to determine the effect of using orthotropic and plagiotropic rootstocks applied by Bacillus and Pseudomonas on the early growth of robusta coffee seedlings from cut grafting. The method used was by using a completely randomized factorial design with 2 factors and was   repeated 3 times. The first factor was the use of rootstock cuttings which consisted of 2 levels, which were S1 (orthotropic stem) and S2 (plagiotropic stem). The second factor was the concentration of Bacillus and Pseudomonas which consisted of 5 levels, which were B0 (0 ml/L), B1 (20 ml/L), B2 (40 ml/L), B3 (60 ml/L) and B4 (80 ml/L). The results showed that (1) there was no interaction between the use of variatic rootstock and the application of the biological agent (2) The use of orthotropic rootstock increased plant growth, that is the number of primary roots and the number of leaves and (3) Application of the biological agent of Bacillus and Pseudomonas with concentrations of B4 increased seedling growth on all observed parameters except the number of shoots. Based on the results of this research, the benefit for coffee planters is to obtain alternative planting materials, namely from orthotropic branches. For further research, the use of orthotropic branch planting material as a scion plant can be investigated.

Abstract

Robusta coffee is a type of coffee that can be cultivated vegetatively. Grafting cuttings technique is one of the propagarion techniques commonly used in Indonesia. The use of auxin and cytokinin hormones can be used in the coffee seedling phase to support the growth of coffee plants. The puspose of this study was to determine the effect of auxin and cytokinin hormones on the growth of robusta coffee seedling in the cuttings grafting method. The method use was a factorial completely randomized design with 2 factors. Factor 1 is the concentration of auxin hormones consisting of 3 levels, namely A1 (0 ppm), A2 (50 ppm), and A3 (100 ppm). Factor 2 consentration of cytokinin hormone which consists of 3 levels namely S1 (0 ppm), S2 (50 ppm), and S3 (100 ppm). The result were analysed using ANOVA and further test using Duncan Multiple Ranage Test (DMRT). The parameters observed were the percentage of cuttings success, number of leaves, number of shoots, shoot height, shoot diameter, chlorophyll content. The result showed that the provision of 50 ppm auxin and 50 ppm cytokinin had the best trend in the variable number of leaves, shoot diameter and shoot height.

Abstract

Arabica coffee cultivation is limited by altitude, which affects its production. Some farmers in Jember Regency are innovating to grow arabica coffee in the lowland, but the potential for leaf rust disease is quite high. Plant natural resistance can be enhanced by adding minerals formulation (containing silica, iodine, and calcium). This research aimed to determine which phase is more effective for applying mineral formulation that induces plant resistance. The formulation was tested on arabica coffee plants grown at the lowland (460 masl) in Jember Regency on 12 years old (y.o) mature and 1 y.o immature plants. One formulation was dissolved in 14 L of water and applied by foliar feeding. The effect was analyzed using two-way T-test of two samples assuming unequal variances at 95% confidence level to determine the differences. The analysis showed that the plants supplemented with the formulation could increase the variables that supported the natural resistance of plants (both mechanically and through the production of chemical compounds), such as polyphenol content, flavonoids, antioxidant activity, total dissolved protein, vitamin C, reducing sugar, lignin, cellulose, hemicellulose, and iodine content in the plant. The response of the formulation application showed that the most resistance variables was better in 1 y.o immature plants than in 12 y.o mature plants. The application of mineral formulation in immature phase will have a better impact on increasing natural resistance, and it has the potential to be used as a supplement for arabica coffee plants cultivated in the lowland.
