Abstract

Soil is a natural resource mostly from the surface of the planet earth that is capable of growing plants and has properties as a result of the influence of climate and living organisms that act on the parent material in certain relief conditions. This shows that an area can have different soil properties. This study aims to Based on the results of research that has been carried out in the pineapple agro-tourism area of Bolaang Mongondow Regency, it shows that the nutrient content of the land is low - very low, while the soil pH on the land is neutral. Thus, efforts to increase nutrient fertility at locations in the area can be done through fertilization of both organic and anorganic fertilizers. determine the chemical fertility of the soil (pH, KTK, N, P, K, Ca and C-organic). Key words: Agrotourism Land, Soil Fertility Abstrak Tanah adalah sumber daya alam yang sebagian besar berasal dari permukaan planet bumi yang mampu menumbuhkan tanaman dan memiliki sifat sebagai akibat pengaruh iklim dan organisme hidup yang bertindak atas bahan induk dalam kondisi relief tertentu. Hal ini menunjukkan bahwa suatu daerah dapat memiliki sifat tanah yang berbeda-beda. Penelitian ini bertujuan Berdasarkan hasil penelitian yang telah dilakukan di kawasan agrowisata nanas Kabupaten Bolaang Mongondow menunjukkan bahwa kandungan unsur hara tanah rendah – sangat rendah, sedangkan pH tanah pada tanah tersebut adalah netral. Dengan demikian, upaya peningkatan kesuburan hara pada lokasi-lokasi di kawasan dapat dilakukan melalui pemupukan baik pupuk organik maupun anorganik. menentukan kesuburan kimia tanah (pH, KTK, N, P, K, Ca dan C-organik).

Abstract

Liquid organic fertilizer is organic fertilizer in liquid form and is generally an organic substance dissolved in a solvent such as water. Organic fertilizers are not only in solid form in liquid form like inorganic fertilizers. This study aims to study the effect of noni liquid organic fertilizer on the growth and yield of shallot plants and to determine the best dosage of noni liquid organic fertilizer on the growth and yield of shallot plants. This study used a completely randomized design (CRD). In this experiment there were 4 treatments, namely P0 : 0% POC (without treatment), P1 : 10% liquid fertilizer made from noni, P2 : 20% liquid fertilizer made from noni, P3 : 30% liquid fertilizer made from noni. Each treatment was repeated 4 times to obtain 16 experimental plants. Parameters observed were plant height, number of tillers, number of leaves, fresh weight and dry weight. Noni fruit as POC did not significantly affect the growth and yield of shallots. The best concentration that can be used for shallots is 20% POC of noni fruit. Keywords. Organic fertilizer, POC, noni fruit, red onion Abstrak Pupuk organik cair adalah pupuk organik yang berbentuk cair dan umumnya merupakan bahan organik yang dilarutkan dalam suatu pelarut seperti air. Pupuk organik tidak hanya berbentuk padat dalam bentuk cair seperti halnya pupuk anorganik. Penelitian ini bertujuan untuk mempelajari pengaruh pupuk organik cair mengkudu terhadap pertumbuhan dan hasil tanaman bawang merah serta menentukan dosis pupuk organik cair mengkudu yang terbaik terhadap pertumbuhan dan hasil tanaman bawang merah. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL). Pada percobaan ini terdapat 4 perlakuan yaitu P0 : 0% POC (tanpa perlakuan), P1 : 10% pupuk cair berbahan mengkudu, P2 : 20% pupuk cair berbahan mengkudu, P3 : 30% pupuk cair berbahan mengkudu. Setiap perlakuan diulang sebanyak 4 kali sehingga diperoleh 16 tanaman percobaan. Parameter yang diamati adalah tinggi tanaman, jumlah anakan, jumlah daun, berat segar dan berat kering. Buah mengkudu sebagai POC tidak berpengaruh nyata terhadap pertumbuhan dan hasil bawang merah. Konsentrasi terbaik yang dapat digunakan untuk bawang merah adalah 20% POC buah mengkudu. Kata kunci.

Abstract

This study aims to determine the effectiveness of ecoenzymes from various basic ingredients of fruit peels on the growth of lettuce (Lactuca Sativa L). This study used a completely randomized design (CRD) consisting of 6 treatments 3 replications, so there were 18 experimental unit parameters namely number of leaves, fresh weight and root weight. Observational data were analyzed statistically which were then further tested for BNT (smallest significant difference) at the 5% level.The results of the research that has been done can be concluded that the use of ecoenzymes from several kinds of fruit is effective for the growth of lettuca plants. The ecoenzyme concentration of several kinds of fruit used is 3% (30ml/1000 ml water). Keywords:  ecoenzymes,  Lactuca Sativa L, plant growth Abstrak Penelitian ini bertujuan untuk mengetahui efektivitas ekoenzim dari berbagai bahan dasar kulit buah terhadap pertumbuhan tanaman selada (Lactuca Sativa L). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 6 perlakuan 3 ulangan, sehingga terdapat 18 parameter satuan percobaan yaitu jumlah daun, bobot segar dan bobot akar. Data pengamatan dianalisis secara statistik yang selanjutnya diuji BNT (beda nyata terkecil) pada taraf 5%. Hasil penelitian yang telah dilakukan dapat disimpulkan bahwa penggunaan ekoenzim dari beberapa jenis buah efektif untuk pertumbuhan tanaman selada. Konsentrasi ekoenzim beberapa jenis buah yang digunakan adalah 3% (30ml/1000ml air). Kata kunci:  ecoenzymes,  Lactuca Sativa L,  pertumbuhan tanaman
