Abstract

The main problem in organic lettuce production in Windujaya Village is low productivity as a result of the planting media relying only on nutrient intake from compost. The purpose of this activity is to introduce tricho-compost technology and liquid organic fertilizer to increase the productivity of organic lettuce plants. The method for carrying out this activity was through technology transfer through training and training carried out with demonstration plots. The results of the activity show that the cultivation of organic lettuce has been using simple technology so that the ability to meet market demand in terms of yield quality cannot be maximally fulfilled. It needs a breakthrough in marketing, not only fresh produce is sold, it needs an effort to be developed into agro tourism. Training in organic lettuce cultivation with biological agent technology and biofertilizers can significantly increase farmers' knowledge and skills in organic lettuce cultivation. The application of tricho-compost technology combined with POC can increase the production of lettuce plants by 20 percent with a profit of Rp. 150,000.00 per 100 polybags and farming efficiency of 1.88.

Abstract

Desa rangkah merupakan salah satu sentra penghasil gula di Kabupaten Kebumen. Terdapat sekitar 51 unit industri gula kelapa dalam skala rumah tangga. Gula kelapa masih diproduksi secara tradisional, menggunakan dapur yang kurang bersih dan laru sintetis (“Sodium metabisulfida”) yang turut andil dalam menghasilkan gula yang tidak sehat. Salah satu program kegiatan yang dilaksanakan adalah pembenahan dapur dan penggunakaan laru alami untuk memperbaiki kualitas gula kelapa menjadi lebih sehat. Kegiatan KKN dapat meningkatkan kualitas dapur sehat sebesar 33,60% dan dengan gula menggunakan laru alami menampilkan warna, tekstur, rasa dan flavor yang lebih disukai daripada gula dengan menggunakan laru sintetis “Sodium metabisulfida”.

Abstract

Coconut plant is the important estate plant to produce brown sugar from neera. Current condition, the neera production is low especially in dry season. The aim of this research was to study the effect of foliar liquid organic fertilizer to increase the coconut neera production in Kebumen Regency. This research was conducted in Coconut People’s Plantation Karanggadung Village PetanahanKebumen from Juli till October 2016. Randomized Completely block design with factorial treatments was used with 3 replications. The first factors was the dosage of liquid foliar fertilizer solution ie 250 mL plant-1 (d1), 500 mL plant-1 (d2), 750 mL plant-1 (d3), and 1000 mL plant-1 (d4). The second factor is interval time of application ie. 1 week (f1), 2 weeks (f2), 3 weeks (f3), and 4 weeks (f4). The observed variables were volume of neera production, pH of neera, sucrosa content, and leaf chlorophyll contents. The result showed that Application of foliar liquid organic fertilizer increase the leaf greenness at 80.55 SPAD unit at three weeks time interval, as reflected the total chlorophyll content. Fertilization of coconut plant with foliar liquid organic fertilizer increase the neera production about 15,32%, and the highest volume of neera was achieved at the dosage of foliar liquid organic fertilizer 750 mL plant-1 with the frequency of application three weeks.
