Traditional petroleum mining is mining that produces liquid and solid waste which can cause environmental pollution. This research aims to determine the impact of traditional petroleum mining waste on surface water quality and calculate the level of surface water pollution. Research was carried out in November, using survey methods and purposive methods to determine the location and collection points for waste water and surface air. Petroleum wastewater and surface water samples have been taken using the grab sampling method. The wastewater samples consisted of 6 samples in the form of 3 samples (B1, B2, B3) from oil wells that were operationally active 24 hours / day. 3 samples (C1, C2, C3) from operational passive oil wells 3 times for 4 hours/day. Surface water samples were taken at 6 points, namely A0 as control, 0km (A1), 0.5km (A2), 1km (A3), 1.5km (A4), 2km (A5). The parameters that have been tested include temperature, TDS, TSS, pH, BOD, COD, DO, fatty oil, ammonia, H2S and phenol. The quality of waste and surface water has been determined based on Minister of Environment Regulation No. 19 of 2010 and Government Regulation Number 22 of 2021. The level of water pollution has been determined using the Pollution Index (IP) method. The results of the research that has been carried out show that TDS, COD, fatty oil, NH3 from active well waste (B) and COD, fatty oil from passive well waste (C) exceed quality standards. Surface water quality has TDS, BOD, COD, fatty oils, NH3, and phenols exceeding class III water quality standards. The level of surface water pollution includes Light Pollution to Moderate Pollution. The farther the sample point is from outlet waste, pollution levels have decreased.

Most of rubber plants in Indonesia are cultivated in highly-weathered soils; therefore, their annual productions are relatively low with the low quality of latex. The aim of this reseach was to increase the latex quality from a rubber plantation grown on low fertility soils by applying a locally-produced organic fertilizer (LOF) to the soils. This research consisted of two steps, i.e. LOF production and a field fertilization experiment. The LOF was made mainly from waste of a latex processing industry. The field fertilization experiment was conducted to assess the effects of LOF additions to the soils on the latex quality. The field experiment was performed using a randomized complete block design with 6 LOF levels, 4 levels of land slopes, and 5 rubber trees in each block, resulting in 120 rubber trees. The LOF levels were 0, 10, 20, 30, 40, and 50 kg tree-1. The LOF contained 17.35% organic-C, 1.14% total-N, 0.53 ppm available-P, and 1.21 cmol (+)kg-1 exchangeable-K, with slightly alkaline pH (pH 8.0). The soil has low fertility status as indicated by the low amounts of total-N and exchangeable base cations (K, Na, and Mg), and very acid pH (pH 4.5). Indicators of latex quality comprising of blockage index, ash-, impurity- and dry rubber-content, and N, P, K contents in the rubber leaves were measured. Although there were no significant differences in most observed latex properties due to LOF addition, their values tended to be higher when the rubber trees were fertilized with LOF. Apparently N and K contents in the rubber leaves are better correlated to the latex properties compared to the P content.Â

Vegetation establishment is considered as a critical step of mined land rehabilitation. The growing plants do not only prevent soil erosion, but also play important roles in soil ecosystem development. Their litterfall is the main process of transferring organic matter and nutrients from aboveground tree biomass to soil. Thus, its quantification would aid in understanding biomass and nutrient dynamics of the ecosystem. This study was aimed to investigate the litter production and its decomposition rate in a reclaimed mined land using albizia and sesbania, and theireffects on some soil properties. The litter under each stand was biweekly collected for four months. At the same time litter samples were decomposed in mesh nylon bags in soils and the remaining litters were biweekly measured. Soil samples were taken from 0-15 cm depths from each stand for analyses of soil organic C, total N, and cation exchange capacity (CEC). The results demonstrated that total litter production under albizia (10.58 t ha-1 yr-1) was almost twice as much as that under sesbania stands (5.43 t ha-1 yr-1). Albizia litter was dominated by leaf litter (49.26%) and least as understory vegetation (23.31%), whereas sesbania litter was more evenly distributed among litter types. Decomposition rates of all litters were fastest in the initial stage and then gradually decreased. Sesbania leaf litters decomposed fastest, while albizia twigs slowest. Differences in the litter production and decomposition rates of the two species had not sufficiently caused significant effects on organic-C, total N, and CEC of the soilsafter one year of revegetation.Keywords: Albizia (Paraserianthes falcataria), decomposition rates, litter, mined land, Sesbania grandiflora

Intensive agriculture has been well known to cause decline in soil organic matter and nutrient content of the soils. Therefore, efforts should be taken to avoid this from happening. Addition of organic fertilizers like compost has been increasingly become more important in Indonesian agriculture in the last couple of decades. The objectives of this study were to produce high quality compost using Indore method and to investigate its effects on organic-corn production. The study was conducted in the Integrated Agriculture Zone (IAZ), University of Bengkulu for two years (2012 and 2013). The study consisted of three steps: (i) soil fertility identification, (ii) compost production, and (iii) organic-corn field production. Soil fertility identification involved physical, chemical, biological analysis of soil samples collected from less fertile and moderately fertile soils. A randomized completely block design was employed in the field study which involved five rates of compost and two levels of soil fertility with three replications. In 2012, high quality compost was black, had pH 8, fine, odorless, and sufficiently high in NPK contents. Organic-corn yielded 2.94 and 5.69 Mg ha-1 of dried kernels on less fertile and moderately fertile soils, respectively at 20 Mg ha-1 compost. Similarly, in 2013 high quality compost was black, had pH 8, moderate, odorless, and high in NPK contents. The corn yields were 3.75 and 1.93 Mg ha-1 on less fertile and moderately fertile soils, respectively at 22.50 Mg ha-1 compost.

Penggunaan Latosol sebagai lahan pertanian bagi tanaman cabai memiliki faktor pembatas yaitu kandungan hara yang rendah, oleh karena itu pemberian pupuk menjadi penting. Tujuan penelitian ini adalah untuk mengetahui respon pertumbuhan vegetatif tanaman cabai di tanah Latosol terhadap konsentrasi dan cara pemberian Pupuk Organik Cair (POC). Percobaan dilakukan pada tanaman cabai rawit yang ditanam pada polybag menggunakan metode Rancangan Acak Lengkap (RAL) dua faktor dengan kombinasi (3x3) + 1 kontrol. Faktor Pertama yaitu konsentrasi POC, terdiri dari kontrol (0 ml/L), 5 ml/L, 10 ml/L, dan 15 ml/L dan faktor kedua yaitu cara pemberian POC pada tanaman meliputi pemberian melalui tanah, melalui daun, dan kombinasi melalui tanah dan daun. Setiap perlakuan diulang sebanyak 3 kali. Parameter pengamatan meliputi sifat kimia tanah, POC, dan pertumbuhan tanaman. Data hasil yang diperoleh kemudian diuji dengan menggunakan analisis ragam (ANOVA) dan uji Contrast Orthogonal untuk mengetahui beda nyata antara perlakuan dan kontrol, bila ada pengaruh dilanjutkan dengan uji DMRT pada taraf 5%. Hasil penelitian menunjukkan pemberian POC konsentrasi 15 ml/L melalui daun (A2D3) secara signifikan meningkatkan jumlah daun, bobot segar akar, dan bobot segar tanaman. Sementara itu, pada konsentrasi yang sama pemberian melalui tanah (A1D3) meningkatkan nilai N-total, P-tersedia, dan K-tersedia tanah.
