Cultivation of aren genjah and cocoa with allay cropping system is a cultivation technique aimed at soil conservation and micro environment. Cultivation of plants in the field needs to get the supply of nutrients with fertilization as an effort to increase crop productivity. This study aimed to find out the response to the growth of aren genjah and cocoa plant on the application of NPK Phonska fertilizer and goat manure fertilizer with allay cropping system. The research was conducted in Badak Mekar Village Muara Badak Sub-district of Kutai Kartanegara Regency, East Kalimantan in 2016. The research method used Randomized Block Design (RAK) and repeated 4 times. The factorial experiment includes 2 factors, the first factor is NPK Phonska (N) fertilizer consisting of 3 levels: n0 = 0 kg plant-1 (control); n1 = 0.25 kg plant-1; n2 = 0.5 kg plant-1 and the second factor is goat manure fertilizer (k) consisting of 3 levels: k0 = 0 kg plant-1 (control); k1 = 2.5 kg plant-1; k2 = 5 kg plant-1. The study consisted of 9 treatments and repeated 4 times. Parameters observed: plant height increase, diameter increase and number of midrib/leaf increase. Data were analyzed by variance and if there was a real effect it would be continued with the smallest real difference test at 5% level. The results showed that NPK Phonska fertilizer very significantly on the parameters of plant heightincrease of aren genjahand cocoa plants. The treatment of NPK Phonska fertilizer at a dosage of 0.5 kg plant-1 (n2) gives the best of plant heightincrease aren genjah and cacao.

Phase I research: factorial experiment with NPK Phonska fertilizer (N) included 3 levels: n0 = 0 kg plant-1); n1 = 0.25 kg plant-1; n2 = 0.5 kg plant-1 and goat manure (k) included 3 levels: k0 = 0 kg plant-1; k1 = 2.5 kg plant-1; k2 = 5.0 kg plant-1. Phase II research: factorial experiment with SP-36 fertilizer (p) included 3 levels: p0 = 0 kg plant-1; p1 = 0.25 kg plant-1; p2 = 0.5 kg plant-1 and KCl fertilizer (k) included 3 levels: k0 = 0 kg plant-1; k1 = 0.25 kg plant-1; k2 = 0.5 kg plant-1. Phase III research: factorial experiment with SP-36 fertilizer (p) included 3 levels: p0 = 0 kg plant-1; p1 = 0.4 kg plant-1; p2 = 0.8 kg plant-1 and goat manure (k) included 3 levels: k0 = 0 kg plant-1; k1 = 7.5 kg plant-1; k2 = 15 kg plant-1. Observation variable phase I research : increase in plant height at 6 months and 18 months after treatment (bsp), increase in stem diameter at 6 and 18 bsp, increase in number of leaves at 6 months of age and yield of cocoa pods. Observation variable phase II research: plant height increase at 3 bsp and 6 bsp, stem circumference at 3 bsp and 6 bsp, yield of cocoa pods, pest and disease attack intensity on cocoa pods. Observation variable phase III research: 1) yield of cocoa pods 2) pest and disease attack intensity on cocoa pods 3) analysis of soil chemical properties: pH, C-organic, N, P, K, alkaline cations, acid cations, cation exchange capacity and base saturation, 4) analysis soil microbes. Data analysis with variance and if significantly different will be Tested for Least Significant Difference (LSD) at the 5% level. Analysis of soil chemical characteristics with the criteria of soil chemical properties Bogor Soil Research Center (PPT) 1983. The results of phase I research: the NPK Phonska fertilizer treatment was very significantly different in the height increase of plants aged 6 bsp and 18 bsp, the increase in the number of leaves aged 6 bsp. The best dose of NPK Phonska fertilization is 0.5 kg of plant-1 (n2). The results of phase II research: the SP-36 fertilizer treatment was very significantly different for all observation variables. The best dose for SP-36 fertilization is 0.5 kg plant-1 (p2). Intensity of pest attack with light damage category and intensity of disease attack with medium damage category on cocoa pods. The results of phase III research: the treatment of SP-36 fertilizer, goat manure and combination of SP-36 fertilizer and goat manure had no significant difference in yield of cocoa pod. The intensity of pest attacks included moderate damage and the intensity of disease attacks included light damage to cocoa pods. The results of the analysis of soil chemical properties were acid soil pH, moderate organic C content, high C/N ratio, low N content, low P content and high K content. The results of soil microbial analysis identified Azotobacteraceae bacteria and Trichoderma fungi.

Daun kelor memiliki banyak manfaat untuk kesehatan dan memiliki nilai ekonomis yang tinggi jika diolah sebagai pangan fungsional. Daun kelor mengandung senyawa yang berfungsi sebagai antioksidan alami sehingga dapat dimanfaatkan sebagai pangan fungsional. Masyarakat yang mengkonsumsi pangan fungsional berbahan baku daun kelor akan mendapatkan manfaat ganda yaitu terpenuhinya gizi bagi tubuh dan dapat mencegah berbagai macam penyakit. Mengingat masyarakat belum banyak mengetahui cara pengolahan daun kelor sebagai pangan fungsional maka perlu dilakukan kegiatan penyuluhan yang bertujuan agar masyarakat memiliki wawasan untuk mengembangkan usaha berbasis bahan baku daun kelor pada skala rumah tangga. Hal ini dapat meningkatkan kebutuhan gizi dan pendapatan keluarga. Hasil kegiatan penyuluhan ini menunjukkan bahwa pengetahuan masyarakat makin meningkat khususnya pengolahan pangan fungsional berbahan baku daun kelor.
