Abstract

Public gold mining carried out without permission and not organized is rife in Riau. Until now there is still lack of information about Unlicensed Gold Mining (UGM) in Kuantan Singingi District specifically Singingi subdistrict, Kuatan Tengah, Sentajo Raya and Logas Tanah Darat. The former gold mining land cannot be used for agricultural activities. To overcome this problem reclamation needs to be done on the former gold mine land. However, before the step is taken, the initial step is mapping the point of the location of the former gold mine, general conditions, land ownership status and mining processes, vegetation in UGM land and the impact of UGM in Singingi subdistrict, Kuatan Tengah, Sentajo Raya and Tanah Darat Logas. This study aims to map the distribution of land of the former gold mine, determine general conditions, land ownership status and mining processes, vegetation of former UGM land and the impact of UGM in Singingi District, Central Kuatan, Sentajo Raya and Tanah Darat Logas, in Kuantan Singingi District. The parameters observed were: point of distribution of the location of the former gold mine, general conditions, land ownership status and the mining process, vegetation of former UGM land and the impact of UGM. The results showed that in all subdistricts sample namely Singingi, Kuatan Tengah, Sentajo Raya and Tanah Darat Logas in Kuantan Singingi Distric there were unlicensed gold mining along the river flow area. Overall land ownership status is owned by individuals/individuals (people with capital) and land used for mining activities that are owned by others rent. There are three types of species that grow on the former gold mine land that is Melastoma malabathricum L., Cyperus halpan L. and Scleria sumatrensis Retz. While the real impact of unlicensed gold mining activities is the loss of river water bodies.

Abstract

Rindu Hati sub-watershed is located in District of Central Bengkulu, Bengkulu Province, that has flat until montainous topography with various slope and annual rainfall up to 4,032 mm year-1 which possible causes erosion. This research was aimed to analyze soil erosion at Rindu Hati sub-watershed based on the Universal Soil Loss Equation formula, using remote sensing imagery data and by applying GIS technique. USLE method were uses five parameters, those were length and slope factor, rainfall erosivity factor, crop management factor and land conservation , and soil erodibility factor. An overlay analysis has been conducted to obtain the erosion. Then, the result is overlaid with soil depth map to get the level of erosion hazard, which is classified into: very light, light, moderate, heavily, and very heavily. The results showed that the total erosion was 12,410,650.59 tons ha-1 year-1, while its level of erosion hazard were very light (15 tons ha-1 year-1) covering an area of 2,983 ha spreading over community agricultural areas and forest areas, the rate of light erosion (> 15-60 tons ha-1 year-1) has the largest area of covering an area of 10,410.05 ha which scattered in plantation areas having flat topography, moderate erosion rates (> 60-180 tons ha-1 year-1) of 1,317.33 ha spread over land areas with shrub land use and relatively flat topography, heavily erosion rates (> 180- 480 tons ha-1 year-1) covering 1,735.48 ha spread over land with shrub land use but has a hilly topography and very heavily erosion rates (> 480 tons ha-1 year-1) covering 2,700.42 ha located in the mining area. Erosion potential rate mapping will be very helpful in determining good and appropirate land management and conservation in the study area.

Abstract

Mustard is one type of leaf vegetable favored by the community because it tastes fresh and contains lots of vitamins A, B, and a little vitamin C. The large area of peatlands in Indonesia and the lack of mineral soils that can be used as agricultural land, make peatland use necessary. Peat is used for agricultural development, with the main limiting factor for growing media conditions that are not conducive to root development, especially land conditions that are saturated with water, react with acid, and contain organic acids at levels that can poison plants, so that some reclamation measures are needed for the land condition peat becomes more suitable for plant development. This study aims to determine the response to the concentration of liquid organic fertilizer (LOF)  and its interaction on the growth of mustard greens (Brassica juncea L.) in peatlands. This research was conducted from April to May 2018 using a completely randomized design (CRD). The treatment given was a dose of LOF consisting of 0; 500; 1000; 1500; 2000 and 2500 L/ha. The variables observed included soil pH, plant height, number of leaves, above-ground fresh weight, below ground fresh weight, above-ground dry weight, and below-ground dry weight. The results of this study indicate that dosing of LOF has a significant effect on plant height, above-ground fresh weight, and above-ground dry weight. However, it did not have a significant effect on soil pH, leaf number, and below ground fresh weight and ground dry weight. The application of the highest LOF at 2500 L/ha was able to increase plant height by an average of 7.75 cm.

Abstract

The development of oil palm plantations in Indonesia as a commodity crop has increased rapidly from year to year. The oil palm plant in Pondok Kelapa District, Middle Bengkulu Regency is the second-largest plantation of people after oil palm. Increasing the income and welfare of farmers can also be done through the evaluation of peatland custom in oil palm crops. This study aims to evaluate the suitability and analyze peatland limiting factors for oil palm plants in Pondok Kelapa District and provide peatland processing direction based on limiting factors to produce palm oil production in Pondok Kelapa District. This research was conducted in Pondok Kelapa Bengkulu Tengah Regency from December 2014 until January 2015 through 4 stages, namely pre-survey, field survey, data analysis, and making a map of the potential development of oil palm plantations. The results showed that each observation point has a low to moderate soil fertility rate It is characterized by low pH and N total values, as well as low P2O5 in providing nutrients for oil palm plants. In general, limiting factors are the dominant limiting factors, namely available nutrients (P2O5, N total) and nutrient retention (pH). The results of land suitability evaluation in Pondok Kelapa District showed the land suitability class is S2 and S3, actual land suitability class for oil palm plants in Pondok Kelapa District with barrier factors hampered drainage, fertility/low soil nutrients, and soil drainage is very hampered/very bad. Efforts to increase peatland potential for oil palm crops can be done by improving drainage, planting systems, and high maintenance of groundwater levels in oil palm plants.

Abstract

Salak (Zalacca edulis Gaertn. Voss) is one of the most populair native fruits of Indonesia, consumed as a table fruit by most Indonesians. However, the yield of salak pondoh grown in Bengkulu is still lower than that in their native soil Java, believed to have more suitable soil properties for growing salak pondoh. The objective of this research were to evaluate the relationship of soil bulk density, available K, and slope to the productivity of salak pondoh grown at Padang Jaya Regency, North Bengkulu. We did a survey to collect data on soil bulk density (BD), available K (K), and slope as well as the productivity of salak pondoh grown at Padang Jaya from November 2017 to May 2017. The results showed that there was a significant relationship between soil characteristics and salak productivity, as shown in a linear model of Y = 2.929 -1.070 BD + 0.069 K - 0.126 Slope. Soil K was positively correlated to salak productivity, suggesting that salak productivity increased with an increase in soil K.  On the other than, soil bulk density and slope were negatively correlelated to salak productivity, indicating that salak productity decreased with an increase in slope and in soil bulk density.

Abstract

Soybean is one of the most popular food crops for the community, but the needs for soybeans have not been fulfilled by soybean production. To meet the needs of soybeans, it is necessary to intensify agricultural land in Ultisol. This study aims to obtain the optimum concentration of humic acid and dosage of the Arbuscular Mycorrhizal Fungi (AMF) to increase soybean plants' production in Ultisols. This research was conducted from January to April 2020 in Beringin Raya Village, Muara Bangkahulu District, Bengkulu City, at an altitude of 10 m above sea level. The research design used a Randomized Complete Block Design (RCBD) two factors with three replications, arranged factorially in experimental units. The first factor is the concentration of humic acid, consisting of 4 levels: 0, 15, 30, and 45 mL L-1 . The second factor is the dose of AMF, consisted of 3 levels, namely: 0, 2.5, and 5 g plant-1. The results showed that the maximum soybean growth and yield in Ultisols were obtained from the humic acid concentration at 45 mL L-1 at the dose of AMF at 2.5 g plant-1 . The resulting production potential is 1.99 tons ha-1 . The administration of humic acid or AMF independently at this research stage had not yet given a maximum response to the growth and yield of soybean in Ultisol.
