PENGARUH PEMBERIAN TANAH DAN SERBUK BAMBU TERHADAP BEBERAPA SIFAT KIMIA LIMBAH ORGANIK DAN ULTISOL LAMPUNG TENGAH
This research was aimed to know the effects of soil and bamboo addition on pH values, content of organic C, total N, total P, total K and total Mg and to know its effect of on chemical properties of Ultisols. This research was conducted in green house of Great Giant Pineapple Company since June to October 2013. This research was designed using Completely Randomized Design (CRD) with two factors, i.e soil addition (0%, 5%, 10% and 20%) and chopped bamboo addition (0% and 20%). Total of the treatments were eight with three replications. This research consisted of two experimental stage. The first stage was the composting of organic waste (cow manure 60%, cassava husk 20% and brommelain waste 20%) for one month and two months while the second stage was incubation of compost in Ultisols for one month. The result showed that soil addition could decrease of pH values, content of organic C, total N, total P, total K and total Mg. The addition of bamboo increased content of organic C, C/N ratio and content of total K and decreased content of total N. The compost incubation for one month did not give any significant effects on chemical properties of Ultisols
Pengaruh Ketinggian AB Mix Terhadap Pertumbuhan Caisim Menggunakan Modifikasi Hidroponik Sistem Wick: The Effect of AB Mix Height on the Growth of Caisim Using the Modified Hydroponic Wick System
Salah satu faktor penting dalam budidaya tanaman secara hidroponik adalah pemberian nutrisi AB mix dengan konsentrasi dan debit yang sesuai. Pemberian dan pengontrolan ketinggian nutrisi tersebut dapat menggunakan modifikasi alat sistem wick yang dirancang berdasarkan beberapa tingkat ketinggian nutrisi. Penelitian ini bertujuan untuk mengetahui pengaruh tingkat ketinggian nutrisi AB mix terhadap pertumbuhan caisim. Penelitian dilaksanakan pada Agustus hingga September 2023 di rumah kaca BSIP Kementerian Pertanian, Cimanggu, Bogor. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan satu faktor yaitu tingkat ketinggian nutrisi AB mix dengan 3 taraf: 2 cm (N1), 3 cm (N2), dan 4 cm (N3) serta menggunakan 6 ulangan. Hasil uji ANOVA menunjukkan bahwa tidak ada pengaruh ketinggian nutrisi terhadap tinggi tanaman, jumlah daun, dan lebar daun pada semua umur pengamatan. Namun, ketinggian nutrisi berpengaruh nyata terhadap panjang akar tanaman caisim yaitu pada perlakuan N1 (18.26 cm) memiliki rerata panjang akar tertinggi dibandingkan perlakuan N2 (14.54 cm) dan N3 (13.77 cm). Hasil tersebut menjelaskan bahwa semakin rendah tingkat ketinggian nutrisi, maka akar tanaman semakin panjang.
Kata kunci: brassicaceae, hidroponik statis, ketinggian air, konsentrasi nutrisi, pertumbuhan tanamanAn important factor in cultivating plants using the hydroponic system is providing AB mix nutrients with the appropriate concentration and solution discharge. Supplying and controlling the nutrient level can use a modified wick system tool designed based on several levels of nutrient height. This research aims to determine the effect of AB mix nutritional levels on choy sum growth. The study was carried out from August to September 2023 in the BSIP’s greenhouse of the Ministry of Agriculture, Cimanggu, Bogor. The design used was a completely randomized design (CRD) with one factor, namely the level of AB Mix nutrient solution in 3 height levels: 2 cm (N1), 3 cm (N2), and 4 cm (N3), and used six replications. The ANOVA test showed no effect of nutrient level on plant height, leaf number, and leaf width at all ages of observation. However, nutrient height had a significant effect on the root length of choy sum plants, which in treatment N1 (18.26 cm) had the highest average root length compared to treatments N2 (14.54 cm) and N3 (13.77 cm). The findings explain that the lower the AB mix height, the longer the choy sum roots.
