Abstract

This unlicensed gold mining activity (PETI) can have a positive impact on the economy of the community, in the form of increased incomes so that it can improve the welfare of the community. However, besides having a positive impact, PETI's activities will harm the environment around the mining area. The negative impact caused by mining activities is environmental damage in the form of a decrease in land quality as indicated by a decrease in physical, chemical and biological soil quality. The purpose of this study was to determine the nutrient content and the total of microbes in former PETI soils in sub-districts of the Kuantan Singingi Regency. The parameters observed were analysis of nutrient content consisting of analysis of sand, dust, clay, soil pH, C-organic, N-total, P2O5, K2O, interchangeable cations, CEC, a saturation of bases, Aluminum Saturation, and analysis of total soil microbes. The results showed that the Singingi sub-district, Central Kuantan sub-district, Sentoja sub-district, and Logas Tanah Darat sub-district has the texture of sand soil clay to sand, the content of pH H2O Land classified as fertility is very sour, C-Organic (%), Ca-dd, Nitrogen-Total (%), Mg-dd and CEC with very low fertility criteria, C/N Ratio with low to very low fertility criteria, K-dd content with low criteria, Na-dd with moderate to very high criteria, aluminum saturation is very high with wet saturation the fertility criteria are low. The total microbes in the Sub-district of Sentoja Raya and Logas Tanah Darat Sub-district are much higher than Singingi Sub-district and Central Kuantan Sub-district.

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

Proses panen nenas akan menghasilkan limbah berupa daun nenas sebesar 2 sampai 3 kg per tanaman. Karena daun nanas tidak dapat dimanfaatkan untuk makanan ternak, jadi biasanya petani hanya membakar serta ada yang membiarkan begitu saja. Salah satu solusinya adalah dengan cara mengolah limbah menjadi serat. Tujuan penelitian adalah untuk mengetahui hubungan antara Panjang dan lebar daun nenas dengan kualitas serat nenas berdasarkan letak daun dan lama perendaman. Penelitian ini dilakukan dengan 2 tahapan, yaitu: 1) Survey lapangan dan pengambilan daun tanaman nanas sebagai sampel; 2) Pembuatan  serat dan uji kualitas serat daun tanaman nanas. Penetapan sampel ditentukan secara purposive sampling yang dilakukan secara sengaja dengan memilih daun tanaman nenas berdasarkan umur panen dan letak daun. Parameter yang diamati dalam penelitian ini adalah panjang daun (cm) dan lebar daun (cm); Kualitas Serat daun nenas terdiri dari Panjang serat, berat basah dan berat kering. Hasil penelitian menunjukan bahwa Panjang daun dan lebar daun terjadi kenaikan nilai panjang daun dan lebar daun pada setiap penurunan letak daun. Semua parameter kualitas serat terjadi kecenderungan penurunan pada setiap perlakuan letak daun dan lama perendaman yang lebih lama. Parameter Panjang daun dan lebar daun yang diamati berkorelasi positif dengan kualitas serat daun nanas berdasarkan letak daun dan lama perendaman daun.

Abstract

Management of peat soil for pineapple cultivation in Kualu Pineapple Village is still very traditional. In planting not using spacing, fertilization only uses fertilizers containing N, namely urea. In addition, there are differences in principles in managing peat, namely that there are farmers who add ameliorant ingredients and some do not. The purpose of this study was to determine the chemical properties of the soil, and nutrient uptake of pineapple plants in Kualu Nenas Village where the soil was given dolomite lime ameliorant and without ameliorant. This research method uses qualitative (survey) and quantitative (laboratory analysis) methods. A sampling of plants whose soil was given dolomite lime ameliorant and soil without ameliorant was carried out by purposive sampling technique. The research data were analyzed by a T-test to determine the difference between the chemical properties and nutrient uptake of pineapple plants. The T-test was analyzed using the SAS program (SAS User Manual Version 9, 2004). The results of this study were that the soil PH, P-available, K-dd, Ca-dd, Mg-dd, CEC, and base saturation content in pineapple plantations where the soil was treated with dolomite lime ameliorant had a significantly higher value based on the T-test compared to pineapple plantations with no ameliorant. Nutrient uptake of N, P, K, Ca, and Mg in pineapple leaves was not significantly different between plants whose soil was treated with dolomite lime ameliorant and those without ameliorant.
