Peningkatan Efisiensi Pemupukan NPK dengan Memanfaatkan Bahan Organik terhadap Hasil Tomat

Penelitian dilaksanakan di Desa Cisurupan Kabupaten Garut, Jawa Barat pada tipe tanah andosol (1.100 m dpl.) pada bulan Juni-Nopember 2002. Penelitian bertujuan untuk mempelajari pengaruh pupuk organik dan dosis NPK baik terhadap pertumbuhan maupun hasil tanaman tomat. Penelitian menggunakan rancangan acak kelompok faktorial dengan ulangan empat kali. Perlakuan terdiri dari dua faktor. Faktor pertama jenis pupuk NPK dan faktor kedua jenis bahan organik. Hasil penelitian menunjukkan tidak terdapat pengaruh interaksi antara jenis pupuk NPK dan pupuk organik. Penambahan pupuk NPK (50 kg N, 75 kg P2O5, dan 75 kg K2O per hektar) dapat meningkatkan tinggi tanaman, diameter batang, dan bobot buah total per petak. Jenis pupuk NPK yang paling efisien terhadap hasil buah tanaman tomat varietas artaloka adalah 50 kg N, 75 kg P2O5, dan 75 kg K2O per hektar. Increasing NPK fertilizer efficiency through organic material utilization on yield of tomato. The experiment was conducted at Cisurupan Village, Garut, West Java on andosol soil type (1,100 m asl) from June to November 2002. The objective of the experiment were to study the influence of organic fertilizer and kind of NPK application on the growth and yield of tomato. Factorial formula of randomized block design with four replicates was used. Treatments consisted of first factor of NPK fertilizer and second factor was kinds of manure. In fact the results indicated that there was no interaction effect between application of organic fertilizers and NPK fertilizer on both of the growth and yield of tomato. The NPK (50 kg N, 75 kg P2O5, and 75 kg K2O) fertilizer was able to increase plant height, stem diameter, and total fruit weight per plot. The most efficient NPK fertilizer formulas on artaloka tomato yield per plant and total weight was 50 kg N, 75 kg P2O5, and 75 kg K2O per hectare

Identifikasi Potensi Dan Kendala Produksi Paprika Di Rumah Plastik

. Adiyoga, W., N. Gunadi, T. K. Moekasan, and Subhan. 2007. Identification of Potential and Constraint of Sweet Pepper Cultivation in Plastichouse. An exploratory survey was carried out in August to October 2003 in sweet pepper production center, Lembang, Bandung, West Java, to obtain general situation of vegetable production technology, especially sweet pepper, in plastichouse, and to identify potentials and constraints of existing cultural practices. There were 17 interviewed farmers that were selected purposively. The results showed that sweet pepper is the most important vegetable cultivated in plastichouse, followed by tomato, cherry tomato, and cucumber. Farmers usually mix 4–14 l of nutrient with 1000 l of water, apply with the dosage of 750–2000 ml/plant/day, as many as 3-5 times/day. The most important pest is thrips, followed by some diseases, such as fusarium wilt, and downy mildew. Estimated production cost per plant is between Rp. 7.000 to Rp. 10.000. The biggest expense is for nutrients, followed by labor, pesticide, seed, and media, subsequently. Outlets mostly used by respondents are assembly markets/traders, private companies, and cooperatives. Maximum price of sweet pepper usually occurs between January and May, while the minimum price frequently occurs between June and August. Efficiency indicators indicate that the R/C\u27s for tomato, sweet pepper, cherry tomato, and cucumber are positive (profitable). Main constraints of vegetable production in plastichouse based on their rank of importance, as perceived by farmers are pest and disease incidence, quality of plastichouse construction, capital availability, labor availability, nutrient availability, pesticide availability, water/irrigation availability, media availability, price fluctuation, and technical information availability. Potentials for further development as reflected by domestic and export market opportunities, are still promising. However, further development should be pursued cautiously, since there is a high dependence on main inputs that are still imported, such as seeds and UV-plastic

A Survey on Feature Recommendation Techniques

Recommendation systems are a very common now days and it is used in a variety of applications. A recommender system that is designed to reduce the human effort of performing domain analysis. Domain analysis is the task in which we can find the commonality and difference between the different software’s of same domain ‘feature recommendation is very useful now a days. This approach relies on data mining techniques to discover common features across products as well as the relationship among these common features. In this paper we used different techniques which are used for domain analysis and feature recommendation. This approach mines descriptions of product from publicly available online product descriptions, uses a text mining and a novel incremental diffusive clustering algorithm to discover features in specific domain , uses association rule mining to know latent relationships between the features within the products of same domain and uses KNN algorithm which generates a probabilistic feature model that represents commonalities, variant.
