Abstract

The use of a hydroponic cultivation system is an alternative to increase the productivity of vegetable plants whose cycles are quite short. It is hoped that the use of the NFT hydroponic technique can increase the productivity of mustard plants. This study aims to determine the effect of different planting media and several varieties on the growth and yield of mustard greens (Brassica juncea L.) using NFT hydroponics. This research was an experimental type that was prepared using a Randomized Block Design (RAK) with 2 factors, namely the use of planting media and varieties with repetition 3 times, and there were 9 treatment combinations. Data were analyzed using ANOVA and tested using the Duncan Multiple Range Test (DMRT) at the 5% level. The results of the research showed that the plant height parameters for the combination of treatment m3v1 using Rockwool planting media and the Tosakan variety for plants were 7 DAP (8.47 cm) and 14 DAP (21.58 cm), as well as the combination treatment m1v1 for using charcoal husk and the Tosakan variety for plants at 28 DAP ( 33.97 cm), leaf number parameters in the combination treatment m1v2 using husk charcoal and the Tosakan variety for 28 HST plants (33.97 cm). Parameters for the number of plant leaves with the m3v3 treatment combination, namely the use of Rockwool planting media and the Kumala variety, 21 HST (11.50 pieces) and 28 HST (24.50 pieces) plants. Key-words: Planting media, NFT, Mustard Greens.                INTISARI                  Penggunaan sistem budidaya hidroponik menjadi salah satu alternatif untuk meningkatkan produktivitas tanaman sayuran yang siklusnya cukup pendek. Penggunaan teknik hidroponik NFT diharapkan dapat meningkatkan produktivitas tanaman sawi. Penelitian ini bertujuan untuk mengetahui pengaruh media tanam yang berbeda dan beberapa varietas terhadap pertumbuhan dan hasil tanaman sawi hijau (Brassica juncea L.) dengan menggunakan hidroponik NFT. Penelitian ini berjenis eksperimen yang disusun dengan menggunakan Rancangan Acak Kelompok (RAK) 2 faktor, yaitu penggunaan media tanam dan varietas dengan pengulangan sebanyak 3 kali, dan terdapat 9 kombinasi perlakuan.

Abstract

This research aimed to determine the effect of LOF concentration from vegetable waste and a combination of planting media on the growth and yield of pak choy plants (Brassica rapa L.). This research was structured in a Randomized Block Design with two factors. The first factor is the POC concentration which consists of 4 levels, namely P0: 0 mL/L, P1: 37.5 mL/L, P2: 45 mL/L, and P3: 52.5 mL/L. The second factor is the combination of planting media which consists of three levels, namely M1: Soil + Charcoal Husk (50% + 50%), M2: Soil + Compost + Charcoal Husk (40% + 40% + 20%), and M3: Soil + Sand + Charcoal Husk (40% + 20% + 40%). The results showed that POC concentration had a significant effect on fresh weight per plant. The combination of planting media has a significant effect on all observation variables. There was an interaction between the two treatments on plant height, number of leaves and fresh weight per plant.Keyword: pak choy, LOF concentration, growing mediaINTISARIPenelitian ini bertujuan untuk mengetahui pengaruh konsentrasi POC asal limbah sayuran dan kombinasi media tanam terhadap pertumbuhan dan hasil tanaman pakcoy (Brassica rapa L.). Penelitian ini disusun dalam Rancangan Acak Kelompok dengan dua faktor.

Abstract

The use of liquid organic fertilizer is an alternative to substitute the use of inorganic fertilizer. Liquid organic fertilizer from tofu waste can be an alternative, but it is necessary to research the appropriate concentration and frequency of administration. This research aims to determine the effect of concentration and frequency of application of liquid organic fertilizer from tofu waste on the growth and yield of lettuce plants (Lactuca sativa L.). This research was structured in a Randomized Block Design with two factors. The first factor is concentration which consists of 4 levels, namely T0: 0 ml/l, T1: 200 ml/l, T2: 300 ml/l, and T3: 400 ml/l. The second factor is frequency consisting of three levels, namely F0: once every 5 days, F1: once every 7 days, and F2: once every 9 days. The results of the research showed that giving liquid organic fertilizer from tofu waste with different concentrations had an effect on plant height, number of leaves and area of lettuce leaves. Providing liquid organic fertilizer from tofu waste with different frequencies had no effect on all observed variables. There was an interaction between treatment concentration and frequency of giving tofu waste POC to lettuce plants. A concentration of 300 ml/l with a frequency of administration once every seven days shows the best results. Keyword: lettuce, concentration, frequency INTISARIPenggunaan pupuk organik cair menjadi alternatif untuk mensubstitusi penggunaan pupuk anorganik. Pupuk organik cair dari limbah tahu dapat menjadi satu alternatif, namun perlu diteliti berapa konsentrasi dan frekuensi pemberian yang tepat. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi dan frekuensi pemberian pupuk organik cair limbah tahu terhadap pertumbuhan dan hasil tanaman selada (Lactuca sativa L.). Penelitian ini disusun dalam Rancangan Acak Kelompok dengan dua factor. Faktor pertama adalah konsentrasi yang terdiri dari 4 taraf yaitu T0: 0 ml/L, T1: 200 ml/L, T2: 300 ml/L, dan T3: 400 ml/L. Faktor kedua adalah frekuensi terdiri dari tiga taraf yaitu F0: 5 hari sekali, F1: 7 hari sekali, dan F2: 9 hari sekali. Hasil penelitian menunjukkan bahwa Pemberian pupuk organik cair dari limbah tahu dengan konsentrasi yang berbeda berpengaruh terhadap tinggi tanaman, jumlah daun, dan luas daun selada. Pemberian pupuk organik cair dari limbah tahu dengan frekuensi berbeda-beda tidak berpengaruh terhadap semua variabel pengamatan. erdapat interaksi antara perlakuan konsentrasi dan frekuensi pemberian POC limbah tahu pada tanaman selada. Konsentrasi 300 ml/l dengan frekuensi pemberian tujuh hari sekali menunjukkan hasil terbaik. Kata kunci: selada, konsentrasi, frekuensi

Abstract

Rice has different varieties, with each variety possessing diverse physical and chemical characteristics. The objective of this study was to analyze the physicochemical properties of several Indonesian local rice varieties. The experiment was conducted from March to April 2017 at the Agriculture Applied Technology Laboratory of the Faculty of Agriculture, Universitas Sultan Ageng Tirtayasa and at the Laboratory of Food Analysis Services in the Department of Food Technology, IPB University. Nine local rice varieties from several areas in Indonesia were used as samples, namely Jalahawara, Ciherang, Pandan Wangi, Rojolele, Sokan, Bendang Pulau, Batang Piaman, Cisantana and Sidrap. Their physicochemical characteristics were analyzed based on some criteria such as: physical quality (weight, length, width, form and percentage of chalkiness), chemical content, water content, ash content, fat content, protein content, carbohydrate content, crude fiber content, starch, amylose and amylopectin content. Data obtained were analyzed by one-way ANOVA using a Randomized Block Design. Jalahawara has the highest percentage of chalkiness. Based on the ratio of length and width, Sidrap and Ciherang were categorized as medium type and the others were oval/round. The heaviest and lightest based on the 1000-grain weight of rice were Ciherang and Bendang Pulau, respectively. The water content was about 2-4% for all samples. The highest and lowest amount of ash and fat content were found in Sidrap and Sokan, respectively. The highest and lowest amount of protein content were found in Batang Piaman and Sokan, respectively. The highest and lowest starch content were observed in Pandan Wangi and Ciherang. The content of amylose and amylopectin was the highest in Batang Piaman. The rice samples were categorized into two groups of low and medium levels of amylose. The low level of amylose was observed in Cisantana, Ciherang, Pandan Wangi and Sidrap, while the medium level of amylose was observed in Jalahawara, Sokan, Bendang Pulau, Batang Piaman and Rojolele.
