Abstract

The aim of this research is to analyze the effect of different types of organic fertilizer (solid biological, liquid biological and foliar) on the growth and productivity of tomato plants. This research was carried out for 3 months starting from February to April 2024. This research used a Randomized Block Design (RAK) consisting of 14 treatments, namely: solid biological fertilizer (100%), liquid biological fertilizer (100%) and foliar organic fertilizer (100%) with inorganic fertilizer doses of 25%, 50% and 75%. There were 14 treatment combinations with 3 repetitions. The observation variables are plant height, number of leaves, stem diameter and plant weight. The results of the research showed that the best treatment for plant height was liquid biofertilizer + 25% dose of inorganic fertilizer (83.47 cm), for number of leaves, namely liquid biofertilizer and leaf organic fertilizer (7 pieces), for stem diameter, 100% biofertilizer (6.20 cm) and for plant weight, namely organic leaf fertilizer + 75% dose of inorganic fertilizer (56.39 g).

Abstract

Tujuan Penelitian ini adalah untuk mengetahui kandungan C-organik dan permeabilitas yang terjadi di Sub DAS Cisangkuy Kecamatan Pangalengan Kabupaten Bandung dan juga pengaruh penggunaan lahan dan kemiringan lereng terhadap C-organik dan permeabilitas tanah di Sub DAS tersebut. Penelitian ini dilakukan dengan metode survei fisiografik secara bebas, peta satuan lahan di buat untuk keperluan dalam pengambilan sampel dilapangan. Sebanyak 27 sampel didapatkan dari penggunaan lahan dan kemiringan lereng yang berbeda di lapangan. Penggunaan lahan yang diamati adalah hutan, perkebunan, dan tegalan sedangkan kemiringan lereng yang diamati adalah 8% - 15%, 16% - 25%, dan 26% - 40%. Hasil sampel yang sudah terkumpul dianalisis di laboratorium untuk menentukan nilai kandungan C-organik dan permeabilitas tanah dan akan di tentukan juga pengaruhnya terhadap penggunaan lahan dan kemiringan lereng menggunakan uji lanjut Duncan Multiple Range Test.Hasil penelitian menunjukan bahwa terdapat pengaruh penggunaan lahan dan kemiringan lereng terhadap kandungan C-organik dan permeabilitas di Sub DAS Cisangkuy Kecamatan Pangalengan. Penggunaan lahan hutan dengan kemiringan lereng 16 - 25% memberikan pengaruh terbaik tehadap kandungan   C-organik (4,21%) di bandingkan dengan perlakuan lainnya dan penggunaan lahan hutan dengan kemiringan lereng 8 - 15% hanya memberikan pengaruh terbaik terhadap permeabilitas (12,87 cm/jam) dibandingkan dengan perlakuan lainnya.Kata kunci: C-Organik, permeabilitas tanah, Sub DAS Cisangkuy ABSTRACTThe objectives of this studi were  to know the soil C-organic content and soil permeability in Sub-Watershed District Cisangkuy, Kecamatan Pangalengan, Kabupaten Bandung as well as the effect of landuse and slope on soil C-organic and soil permeability in the sub-watershed. The methode used was free physiographic survey. Map units are made for the purpose of soil sampling in the field. Sample point to a total of 27 samples taken on a combination of land use and slope. The use of primary forest land is observed, plantations, and farm / moor while the observed slope is 8% - 15%, 16% - 25%, and 26% - 40%. Results of samples already in the analysis can be tested in the laboratory to determined the value of the C-organic and permeability and will be specified as well as its effects on land use and slope using advanced Duncan’s test. The results showed that there is the influence of land use and slope towards the C-organic and permeability in the Sub-Watershed Cisangkuy of Pangalengan. A landuse of the escarpment forest with the slope 16 - 25% only gave the best effect in custom content of C-organic(4,21%)  and a landuse of the escarpment forest with the slope 8 - 16% gave the best effect in custom content of permeability (12,87 cm/hour)  in area of research between other treatment. Key words: C-Organic, soil permeability, Sub Watershed Cisangkuy
