The role of nitrogen in plant growth is well known, but there have been few studies on the response of nitrogen fertilizers to changes in plant anatomy and agronomy. This study aims to observe the response of the tissue and organs of arabica coffee seedlings to adding nitrogen. Nitrogen is used in the urea fertilizer form. This research used a single factor of CRD with five replications. 4 levels were tried without urea fertilizer as a control (N1), dosage of urea fertilizer 15 g urea.plant-1 is equivalent to 6,9 g of nitrogen (N2), dosage of urea fertilizer 30 urea.plant-1 is equivalent to 13,8 g of nitrogen (N3), and dosage of urea fertilizer urea.plant-1 is equivalent to 20,7 g of nitrogen (N4). After application, the plants are incubated for 30 days to allow time for the fertilizer to be absorbed by the plants. The analysis result stated that the chlorophyll content was very significantly different, while other agronomic variables were not significantly different. Less adaptation period was thought to be the cause of the various agronomic variables being not significantly different. This is reinforced by the response that arises in plant tissue. The addition of urea fertilizer responded to the thickness of the mesophyll tissue, the size of the epidermal cells, and the regularity of the lower epidermal cells. The result of this research concluded that the response of plants to the treatment had not yet reached the organ level but was still at the tissue level.

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.

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.

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.

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.
