Abstract

Safitri R, Riswanda J, Armanda F. 2020. Monitoring of  heavy metal polution the lead (Pb) with bio indicator baung fish (Hemibagrus nemurus) at the Musi River of South Sumatra. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 127-138.The high activity of the community in the musi river waters could affect the quality of river water, and can even caused water pollution and aquatic biota including fish baung (Hemibagrus nemurus) by lead heavy metals (Pb). This study aimed to determine the lead (Pb) heavy metal content of baung fish (H. nemurus) catches of fishermen in the musi river waters of palembang city. This research was conducted in May-June 2019. The method used is quantitative descriptive. The sample of this research is the meat, skin, liver, kidney and gill of baung fish (H. nemurus) which are tested for lead (Pb) heavy metal content using aas (atomic absorption spectrophotometry). The results of this study indicated that the concentration of heavy metal the lead (Pb) in fish baung (H. nemurus) in the waters of the musi river on the average meat of 0.046 mg/kg, on the skin of 0.058 mg/kg, in the liver of 0.1516 mg/kg, in the kidney at 0.2513 mg/kg, and in the gills at 0.2216 mg/kg. The Pb concentration on the meat, skin and liver samples were still below the established quality standards so that they were still suitable for consumption while the kidney and fish gill samples are above the quality standards that have been set based on the regulations of the Regulations Drug and Food Control Agency (DFCA) number 5 of 2018 which is equal to 0.20 mg/kg.

Abstract

Sari EK, Lucyana L. 2020. Economic valuation of water quality condition ogan river against the clean water in the district of Ogan Komering Ulu. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 139-148. The existence of the Ogan River has experienced a reduction in water quality, this is caused activities from the community such as disposing household waste and dumping industrial waste into the river. This fact causes the need of protecting the quality of  Ogan river water by using Perusahaan Daerah Air Minum (PDAM) and shallow wells to fulfill the needs of clean water for the community. The use of shallow wells and PDAM caused economic losses to the community. They raise extra costs or replacement costs that must be paid by the community. The purpose of this study was to determine the community's perception of the impact of river water quality and to determine the cost of replacement by using the replacement cost method that must be spent by the community around the Ogan River Basin Ogan Komering Ulu Regency. The method used descriptive analysis, and a replacement cost approach for a year. The total population of 3,329 is family head (KK).  The samples in this study amounted to 149 KK. The perception of people who want to improve the quality of the river Ogan by 90.6 percent and of  88.6 percent of the public said it would remain in the vicinity of the Ogan River despite the condition  change or increasingly bad. . In this study was take the reason people remain 51 percent is due to an economic factor. Regarding the economic valuation of clean water aspects, 71.8 percent of the people use PDAM, 25.5 percent use well water and 2.7 percent use river water as a source of clean water. The estimated cost of replacement costs incurred for one year is Rp102,510,000 and the need for clean water is 20,502 m3/year. The total costs incurred by the community amounted to Rp 357,852,500.

Abstract

Agustriani F, Purwiyanto AIS, Putri WAE, Fauziyah F. 2020. Biodiversity of fishes in musi estuary, South Sumatra, Indonesia.  Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 192-198.The high activity in the Musi estuary will have an impact on fishes diversity. This research aimed to analyse the biodiversity of fishes in the Musi estuary in South Sumatra. An experimental fishing method was used for data collection by fishing ground following the local fishermen habit using gillnet millennium. The abundance of fish species found were 21 species and 16 families. The main catch was Hemibagrus nemurus with a high relative abundance (RA) of 35.4% but the high availability frequency of 100% is Eleutheronema tetradactylum. The average value of the moderate diversity index (H'= 1.47), the moderate evenness index (J'= 0.48) and the low dominance index (D= 0.32). This condition shows that the community structure of the species captured by the gill net is in a fairly stable condition with the number of species that are spread fairly evenly and no species dominate each other.

Abstract

Firmansyah MA, Bhermana A. 2020. Characterization of earthworms (Lumbriscus terestris) population under several area of shallots cultivation. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 208-217.In General, the problem of shallot commodities development was still used common farming without considering land suitability and other specific soil condition including aspect cultivation. The objective of this study was to clasify several lands characteristics for shallots cultivation and to observe earthworm (Lumbriscus terrestris) population based on their land suitability classes. The methodology used was land evaluation approach and field observation. This study was performed during  rainy season in 2018 at three locations with different soils, namely, peat soils/Histosol (IST), buried soil of Quartzipsamment above peat soils (ENT), and dry land of Dystropept (EPT). The population of earthworms is obtained by digging up an area of 1 m2 with depth of 20 cm at in four places of location of study. The calculation of earthworms is conducted by hand sorting. The results showed that the highest land suitability class at EPT S3tr, rt, nr, while for other locations are not suitable. The location of IST is classified into N3fb with several limiting such as flooding hazard during rainy season, while for ENT location, classified into Nrt, limiting factor is rough texture. High suitability class is not identical with high earthworm population density. Cultivation aspect that is able to increase soil pH become neutral condition and lower pesticide application affect earthworm populations. ENT locations that have neutral soil pH with lower pesticides applcation have the highest earthworm populations. Earthworm population density from high to low involve ENT> IST> EPT or 74> 33> 31 tails/m2.

Abstract

Dryland area in Indonesia reaches 108.8 millions ha (69.4%) of the total dry land with the potential to expand the area of food crops reaching 7.1 million ha, which is dominated by ultisol and oxisol soil types. Plant constraint cultivation on ultisol soil types is the acidic soil pH with high Al and Fe levels. One of the efforts that can be made to cultivate plants on ultisol soil is the selection of plants that are tolerant of Fe stress. This study aimed to determine a tolerance level and F6 red rice lines that were tolerant of iron (Fe) stress in ultisol soils. The experimental design used was factorial Completely Randomized Design (CRD) consisting of 2 factors, the first factor consisted of 12 treatments (10 test lines and 2 comparison varieties) and the second factor  was iron stress with concentrations (0 ppm and 551,55 ppm). The stress was applied after 3 WAP. The stress resistance test to iron (Fe) should that all lines of red rice F6 on ultisol soils have a score of 1 which indicates the stress tolerance of Fe at a concentration of 551,55 ppm Fe. The 23A-56-30-25-12 and 23A-56-30-25-13 lines were the best lines that were tolerant of 551,55 ppm iron (Fe) stress with the highest growth and yield. The lines tested can be developed on ultisol soils because they are tolerant of Fe.

Abstract

Cultivation of okra on ultisol soils having poor physical, chemical and biological soil properties can be improved by administering a bio-stimulant extract of golden snails and combined with NPK fertilizer. This research objective was to study a combination of bio-stimulant treatment of golden apple snail extract and NPK fertilizer dosage in increasing the growth and yield of okra on ultisol soil. This study used a factorial completely randomized design with two factors.  The first factor was Bio-stimulant golden apple snails extract consisting of 4 treatment, and the second factor was levels of NPK fertilizer consisting of 3 treatment. Fertilizers had a significant effect on increasing overall plant growth.  The bio-stimulant extracts of golden apple snails contain organic materials that can improve physical properties (increasing aggregation, moisture retention, soil hydraulic conductivity), chemical (increasing soil organic carbon content) and biology (increasing soil microbial biomass). The nutrient content in NPK fertilizers can increase nutrients; the availability of nutrients in the soil is balanced and can be absorbed by plants so that the photosynthesis process in plants can run well and increase on growth and yield of okra. The combination of bio-stimulant extract of golden apple snails of 20 mL/L water and NPK fertilizer of 150 kg/ha (1 g/polybag) had the highest resulted in the average value of growth and yield of okra on the ultisol soils.

Abstract

Farmers' institutions, whether fostered by the government or those that have emerged from the initiatives of non-governmental organizations (NGOs), have an important position in developing vegetable agribusiness. This research aimed to compering the institutional dynamics of government-assisted farmers and non-government organizations and to formulate a collective learning institutional framework. The survey method was carried out by taking disproportional stratified random sampling, the data were analyzed using scoring, chi-square crosstabs and SWOT analysis. The results of this study indicate that the institutional dynamics of farmers are on average in moderate criteria with differences in dynamic indicators. Government-assisted groups prioritize achieving agribusiness goals, while NGO-assisted groups develop an egalitarian structure. Factors that significantly influence the institutional dynamics of farmers are farmer age, education, status in the organization, and access to credit. The joint learning framework from the technological aspect is aimed at discovering, sharing and using vegetable agribusiness development technology. Meanwhile, from the institutional aspect, it is aimed at strengthening organizations and networks.
