Abstract

   Immobilization of Pb in the form of bonds with inorganic compounds can occur with the availability of large amounts of solubilizing phosphate in the rhizosphere. High solubilizing phosphate in the rhizosphere can be an indication of the presence of phosphate solubilizing bacteria that work effectively in the rhizosphere. Exploration, isolation and characterization of these beneficial bacteria need to be carried out, so that strains that are able to grow well in rice growing areas can be propagated as biofertilizers. The purpose of this study was to examine the content of lead (Pb) and the characterization of phosphate solubilizing bacteria in rice planting areas in Sungai Kakap District, Kubu Raya Regency. This study used a field experiment method. Soil samples from the rice plant rhizosphere and rice plant samples were analyzed in the laboratory according to the variables that had been determined. The results of this study indicate that the available phosphate content in paddy fields in Sungai Kakap District ranges from 0.58 to 13.38 ppm. The paddy field in Sungai Rengas Village has a high available P content, while the paddy field in Sungai Kakap Village has a very low P status. The results of analysis of total Pb in the rice fields of Sungai Kakap District ranged from 11.55 to 18.71 ppm, the status of total Pb content was classified as low. The relationship between the availability of P in the soil and the levels of Pb is very low (r = -0.33), it is suspected that Pb does not affect the state of P in the soil due to the low concentration of Pb. The ability of bacterial isolates to dissolve phosphate in this study varied. Phosphate solubilizing bacterial isolates from rice roots had a greater ability to dissolve phosphate than isolates from paddy soil, both isolates from the rice fields of Sungai Rengas Village and Sungai Kakap Village.Keywords: Phosphate Solubilizing Bacteria, rice, paddy fields, lead.INTISARIImmobilisasi Pb dalam bentuk ikatan dengan senyawa anorganik dapat terjadi dengan tersedianya solubilizing fosfat dalam jumlah besar di rhizosfer. Solubilizing fosfat yang tinggi di rhizosfer dapat menjadi indikasi adanya bakteri pelarut fosfat yang bekerja effektif di rhizosfer. Eksplorasi, isolasi dan karakterisasi bakteri yang menguntungkan ini perlu dilakukan, agar strain-strain yang mampu tumbuh baik di areal pertanaman padi dapat diperbanyak sebagai biofertilizer. Tujuan penelitian ini adalah mengkaji kandungan timbal (Pb) dan karakterisasi bakteri pelarut fosfat pada areal pertanaman padi di Kecamatan Sungai Kakap Kabupaten Kubu Raya. Penelitian ini menggunakan metode eksperimen lapang. Sampel tanah dari rhizosfer tanaman padi dan sampel tanaman padi dianalisis di laboratorium sesuai dengan variabel-variabel yang telah ditentukan. Hasil penelitian ini menunjukkan kandungan fosfat tersedia pada lahan sawah di Kecamatan Sungai Kakap berkisar 0,58 – 13,38 ppm. Lahan   sawah Desa Sungai Rengas memiliki kandungan P tersedia dengan status tinggi, sedangkan lahan sawah di Desa Sungai Kakap status P tersedianya sangat rendah. Hasil analisis Pb total di lahan sawah Kecamatan Sungai Kakap berkisar 11,55- 18,71 ppm, status kandungan Pb total ini tergolong rendah. Hubungan antara ketersediaan P di dalam tanah dengan kadar Pb sangat rendah (r = - 0,33), diduga Pb tidak mempengaruhi keadaan P di dalam tanah karena konsentrasi Pb yang rendah. Kemampuan isolat bakteri dalam melarutkan fosfat pada penelitian ini berbeda-beda. Isolat bakteri pelarut fosfat yang berasal dari  akar padi mempunyai kemampuan melarutkan fosfat yang lebih besar dibandingkan isolat dari tanah sawah, baik isolat yang berasal dari sawah Desa Sungai Rengas maupun Desa Sungai Kakap. Kata Kunci: Bakteri Pelarut Fosfat, padi, sawah, timbal.

Abstract

The development of tidal land for agriculture faces various challenges in order to provide high productivity. One of the plant cultivation techniques developed in tidal areas is water saturated cultivation. This research aims to determine the growth and yield of flowering cabbage in acid sulphate tidal fields using a water-saturated cultivation system applied with various amelioran compositions. This research was carried out in Kalimas village, Sungai Kakap District, Kubu Raya Regency for 8 months (April – October). The research design that will be used is a field experiment with a split plot design with 2 treatment factors and 3 replications. The main plot is the Flower Cabbage variety (K) which consists of 2 varieties: k1 = Larissa F1 and k2 = Snow White F1. As a subplot is the amelioran composition (A) which consists of chicken manure (pka), goat manure (pkk), biological fertilizer (ph) and dolomite lime (kd) with 8 compositions, namely: a1 = pka, a2 = pkk, a3 = pka + ph a4 = pkk + ph, a5 = pka + kd, a6 = pkk + kd, a7 = pka + ph + kd, and a8 = pkk + ph + kd. The results of the research show that the amelioran composition has the same effect, while the variety and depth of the water table have a different effect on the growth of flowering cabbage plants on acid sulfate tidal land with a water-saturated cultivation system. The Larissa variety provides better growth than the Snowhite variety.

Abstract

            The use of manure and lime in cultivation of cauliflower plants on acid sulfate alluvial soil can improve the physical, chemical and biological properties of the soil so that it can increase the growth and yield of cauliflower. The aim of this research is to determine the best combination of manure and lime for the growth and yield of two cauliflower varieties planted on tidal land with a saturated soil culture system. The research location is located at Golden River Camp, Jalan Kalimas Tengah, Kalimas Village, Sui. Kakap District, Kubu Raya Regency, West Kalimantan. The research period was from July to November, 2023. The research design used Split Block with two treatment factors and was repeated in 3 times. The first factor consists of 2 levels, namely the Larissa and Snow White varieties. The second factor was a combination of manure and lime treatment, consisting of 4 levels, namely chicken manure; goat manure; chicken manure + lime; and goat manure + lime. The variables observed were number of leaves, fresh weight, dry weight, leaf area, flower emergence time, crop weight, and crop diameter.

Abstract

Scallions ( Allium fistulosum L.) are a horticultural crop commodity that is worthy of intensive development in Indonesia, especially in Pontianak, West Kalimantan Province. Peat soil has great potential for the development and cultivation of spring onions. Efforts that can be made to overcome the very low availability of nutrients are cow manure. One cultivation technique that can be used to increase leek production is by adjusting plant spacing. This research was carried out on research land located on Jalan Sungai Raya Dalam, Alam Mulia Housing Complex starting on 15 September – 2 November 2023. This research aims to obtain the best dose of cow manure for the growth and yield of leek plants on peat soil and to obtain the best planting distance for the growth and yield of leek plants on peat soil. This research was carried out using a field experimental method with a Split Plot Design pattern , namely: The first factor is the distance between the plants for the main plot: j 1 = 20 cm x 20 cm, j 2 = 20 cm x 25 cm and j 3 = 20 cm x 30 cm. The second factor is cow manure as a sub plot: p 1 = 10 tonnes/ha, p 2 = 20 tonnes/ha and p 3 = 30 tonnes/ha. The observation variables consist of: Root Volume, Plant Dry Weight, Number of Leaves/clump, Plant Height, Number of Saplings/clump and Fresh Weight of the plant. From research that has been carried out, the interaction of using a planting distance of 20 x 25 cm and 10 tonnes/ha of cow manure shows the best growth and yield of leek plants on peat soil.
