“…Pada penelitian ini hasil kopi per pohon relatif rendah yaitu berkisar 110-300 g per pohon. Rendahnya hasil ini juga dilaporkan oleh Rusli et al (2015) yang melakukan penelitian dosis pemupukan pada beberapa nomor klon BP. Hasil penelitian ini juga menunjukkan produktivitas yang dicapai relatif rendah yaitu antara 2-6 kuintal per hektar.…”

Grafting of different coffee species (interspecific grafting) aims to take advantage of the superiority of the rootstock and promote the growth and production of the scion. For example, Robusta coffee is grafted with Liberika coffee as rootstock. One of the principles of fertilization is the application of fertilizer at the right time. This study aimed to determine the effect of clones of Robusta/Liberica interspecific grafting and different fertilization times on the growth and yield of Robusta coffee. The research was conducted in a 15-year-old coffee plantation with the rootstock of Liberika coffee of the Red Robinson variety which was grafted to the scion of multiclonal Robusta coffee. Planting distance of coffee was 2.5 m x 2.5 m and shade trees were Gliricidia sepium. This research used a split plot design arranged in a factorial (4x2) with three replications so that there were 24 experimental units. The main plot was the time of fertilization, namely in early April and October and in early May and November. As sub-plots, there were Robusta coffee clones, namely Korolla 1, Korolla 2, Tugu Bungkuk, and Darmani. The results showed that fertilization time, clones, and their interactions did not affect the number of primary branches, primary branch length, number of secondary branches, fruit weight of harvested samples, number of fruit per bunch, fruit weight per bunch, dry seed weight per bunch, and coffee yield per tree. The interaction of coffee clones and fertilization time had a significant effect on the number of pods per branch, the number of harvested samples, dry bean weight of harvested samples, dry bean weight per branch, and coffee yield per hectare. For Darmani coffee clones, delaying fertilization from April and October to May and November reduced coffee yield. Key words : Interspesific grafting, Liberica, Robusta, time of fertilization, yield

“…Pada perlakuan BI5 terdiri atas biochar 1% + pupuk KNO3 dimana pupuk KNO3 mampu meningkatkan nilai pH tanah sedangkan perlakuan BI4 yang terdiri atas biochar 1% inkubasi Trichoderma 1 mL + pupuk urea dimana pemberian urea pada tanah agak masam dapat meningkatkan keasaman tanah tersebut (Pangaribuan et al, 2017). Kandungan N-total termasuk kategori sangat rendah hal tersebut karena dosis pemberian pupuk N yang masih kurang atau sebanyak 20 g th -1 (Rusli et al, 2015). Menurut Manik dan Ali, (2018), pemberian dosis N sebanyak 5 g yang paling baik, hal ini karena telah mampu menambah unsur hara secara optimal di dalam tanah dan dapat meningkatkan kesuburan tanah.…”

Coffee is a source of foreign exchange that plays an important role in the development of the plantation industry. However, many coffee-producing regions have experienced quite detrimental yields in recent years due to the rust of coffee leaves (Hemileia vastatrix), a parasitic fungus that reduces yields and that can ultimately kill coffee plants. The use of biochar enriched with Trichoderma can help to improve soil conditions and increase crop production because biochar can increase the availability of N and P. Trichoderma as a biocontrol agent that can help in solving the problem of coffee leaf rust. This study that was conducted at Gondorejo Village, Oro-oro Ombo sub-district, Batu District used a completely randomized design with seven treatments and four replications. The results showed that the application of media with a composition of 1% biochar enriched with Trichoderma supported the growth of Arabica coffee seedlings at the age of 3 months. It can be seen from the available N content, which showed an increase and the number of leaves which had the highest increase among other treatments. This indicated that the composition was sufficient to support good media for the growth of Arabica coffee seedlings.

Agroforestry systems have significant potential for development in increasing coffee production in Indonesia. Besides providing economic benefits, agroforestry can also have ecological impacts, such as improving soil structure, reducing erosion, and other environmental services. There is a complex interaction between trees, soil, and crops in agroforestry systems, making modeling a valuable approach to unraveling these processes. We utilized the spatial and temporal explicit model WaNuLCAS to (i) evaluate the model's performance in depicting actual events (through coffee production and soil water content), (ii) assess the dynamic processes influencing coffee production and the environmental impact of management patterns, (iii) formulate and simulate optimal scenarios for coffee production optimization. Data from a one-year period involving five agroforestry management patterns for coffee-pine in UB Forest were used as input for the model. The model validation results showed satisfactory and acceptable outcomes for coffee production and groundwater dynamics. WaNuLCAS simulation results indicated that pruning and thinning management are crucial factors in increasing coffee production and are related to creating optimal conditions for coffee plants (light, humidity, and inter-plant competition). Additionally, fertilization management can be combined as a supporting factor to meet the nutritional needs of coffee plants. WaNuLCAS simulation results also suggested that pruning and thinning can improve soil physical properties, but thinning increases surface runoff within the system. This research provides insights into how modeling can be used as a decision-making tool.
