Abstract

The change of several soil nutrients in tidal swamp area due to addition of palm oil mill effluent (POME) on soil media. The research objective was to determine the effect of different dosages application of palm oil mill effluent on nutrient changes within planting media. This experiment was conducted in a plastic house by using 8 month ages of plants consisting of 9 pots combined with 6 levels of BOD treatment (Biological Oxygen Demand) concentrations as follows: 20.000 mg/l (L5), 15.000 mg/l (L4), 10.000 mg/l(L3), 5.000 mg/l (L2), 2.500 mg/l (L1) and water only (Lo). The plants were grown for six months from December 2014 to June 2015. The variables observed were pH (H2O), pH KCl, C-Organic, N-Total, P-Bray I (ppm), K- dd, Na, Ca, Mg, Cation Exchange Capacity, Al-dd and H-dd as well as N, P and K nutrients of crop tissues. The results showed that addition of palm oil mill effluent increased soil pH and availability of soil N, P, K, Ca and Mg. Meanwhile nutrients content of N, P and K in tissues were not increased significantly by given POME with BOD up to 20.000 mg/l.

Abstract

Nuryenti, et al. Content of Hara N, P, K on Gawangan and Harvest Road Oil Palm Plantation. JLSO 5(2):219-224. Differences in the location of oil palm plantations cause differences in nutrient content contained in the soil. This study aims to analyze the nutrient content of N, P, K of soil on gawangan and harvest road in PT. Sawit Mas Sejahtera. The method used is a detailed survey method with an observed area of 3 ha. Soil analysis results in nutrient content of N, P, K on harvest road showed higher yield compared to gawangan. N-total value on gawangan 0.11% and 0.16%  harvest road, P-bray value on gawangan 6.15 ppm and 15 ppm harvest road, K-dd value on gawangan 0.10 me/100 g and 0.41 me/100 g harvest road. Soil pH on harvest road and gawangan is a very low pH soil ranging from 3.84 to 4.22. Palm oil production may increase by adding calcification first before the application of N, P, K fertilizer especially on harvest road to improve soil fertility and produce optimal production.

Abstract

Aksani, et al. Soil Bacteria Population in Paddy Tidal Land by Application of Liquid Fertilizer Neptunia prostrata. JLSO 5(2):170-177. High soil acidity in tidal lowland influences soil bacteria population. This research aimed to determine soil bacteria population with liquid fertilizer application made by Neptunia prostrata for paddy grown in tidal lowland. This research using factorial completely randomized design with two factors and three replications. The first factor was liquid fertilizer rate, consisting of three levels: 96 mL pot-1(P1), 120 mL pot-1(P2) and 144mL pot-1(P3). The second factor was application period consisting of three times: once time at the planting time (W1), two times at the planting time and harvesting time and three times at the planting time, primordial stage and harvesting time. The result showed that the highest soil bacteria population was 10,94 log spk g-1with the treatment of  144 mL pot-1 liquid fertilizer and given once time at the planting time (P1).

Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 184-191.Riparian wetland is highly available and potential suboptimal lands for an alternative solution in extending agricultural activity, but several constrains need to be resolved. The objective of this study was to improve the diversification of vegetables for increasing riparian wetland with utilizing floating cultivation system. This study was conducted From November until December 2019 in Jakabaring (104°46’4” E; 3°01’35” S) Palembang. The design of experiments used in this study was arranged in split plot-completely randomized design with 2 factors (main plot and sub-plot). Main plot was the height of water table, namely: R1 (1 cm upper raft surface), R5 (5 cm upper raft surface), and R10 (10 cm upper raft surface). Sub-plot was the size of celery tiller, i.e., B1 (big size) and B2 (small size). Each combination treatment consisted of five replication. Results showed that there was no any significant effect on water table and tiller size combination treatments in all observed variables, such as: plant height, leaf area, number of petioles, root length, fresh weight, and dry weight of shoot and roots. But, root length was significant different in water table treatment. Therefore, cultivated celery using floating culture system from tiller of parent plants can be an alternative to increase agriculture activity by shortening the planting period to increase vegetable diversification in riparian wetland.

Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 199-207.Indonesia imported very high amount of date palm fruits about 9.99 million kg or US$ 13.18 M, because of that it is necessary to develop a research about date palm seedling nursery and investigation of female date, since this is a dioecious plant. The aim of this investigation was to find out characteristics of female date seedling and the effects of seedling age and compost on seedling growth. There were 2 steps in this research: the first was application of compost on seedling (without and plus compost treatments) and the age of seedling (15 and 30 days old) for transplanting into polybag, the growth ability of plant was monitored. The second step was transplanting seedling at 30 days old into pan for investigation female date, which 20 seedlings were planted in one pan and replicated 3 times.  Results showed that compost increased roots and leaves growth on seedling.  Transplanted at 30 days old seedling had the ability to grow about 95% compared to 15 days old was only 45%. It was found that female seedling was about 25% and the rest (75%) was male or sterile. It is needed further investigation on growing female seedling in the field and can it produce fruit.

Abstract

Lubuk Karet River is a river that surrounded by swamps with various kinds of plants and grasses. The Lubuk Karet River has the potential for the development of aquaculture which can be the business part of Lubuk Karet village community. This research was aimed to conduct an assessment effort in order to measure the capability of Lubuk Karet River for any aquaculture activities. The method used in this study is purposive sampling by conducting water quality assessment through biological and chemical parameters to support the development in that region. The results of this test can be a benchmark of fish species that can be cultivated in the Lubuk Karet River. The results of the chemical and biological parameters showed that the lowest DO content at station 2 was 3.11 mg/L and the highest BOD content at station 1 was 4.7 mg/L, the highest at station 1 was 606 mg/L, the highest TSS content 50 mg/L, the highest nitrate content at station 1 was 6,54 mg/L, the highest phosphate content at station 2 was 0.098 mg/L, the highest COD content at station 2 was 5,61 mg/L, Salinity was 0, the highest content at station 2 was 9,71 mg/L and the lowest pH value at station 5 was 2.96. From these results, it can be concluded that for further utilization for aquatic culture, some treatments must be conducted.
