Main Plot

Technology of microbial utilization to accelerate the oxidation of pyrite followed by leaching (bioleaching) has the potential to resolve problems in land management of actual acid sulphate soil. The research aims to obtain a bioleaching technology package that can improve the productivity of the actual acid sulfate soil. The experiment was conducted on tidal swamp land that has soil type of actual acid sulfate at Wana Raya sub-district, district Batola, South Kalimantan, in July - November, 2014. The study was designed by using strip plot with three replications. The treatment consisted of two factors, namely application of an oxidizing microbial pyrite and leaching amount (intensity). The main plot consisted of (P0) without leacing (naturally), (P1) six times leaching , (P2) eight times leaching, and (P3) 12 times leaching. Subplot consisted of (M0) without oxidizing microbial pyrite, (M1) with oxidizing microbial plant used in this study is Inpara 3 of rice variety. Observations were made on soil pH, oxidizing bacteria pyrite, growth of rice plants (plant height and number of tillers) and rice yield. The results showed that the main problem of actual acid sulfate land studied is a high soil acidity (pH of 3.44). Influ-ence of leaching was greater than microbial application on crop yields. Application of the pyrite oxidizing bacterial and leaching eight times gave the best influence on the growth and yield of rice plants.

Penelitian dilakukan bertujuan untuk mengetahui pengaruh remediasi tanah pada budidaya udang windu di tambak tanah sulfat masam. Penelitian dilakukan pada tambak milik masyarakat di Pulau Tempurung, Desa Kasai Kecamatan Pulau Derawan Kabupaten Berau Provinsi Kalimantan Timur. Karakterisasi tanah untuk mengetahui rona awal tambak tanah sulfat masam dilakukan sebelum budidaya. Prosedur perbaikan tambak tanah sulfat masam diadopsi dari hasil penelitian Balai Riset Perikanan Budidaya Air Payau dan Penyuluhan Perikanan (BRPBAPPP). Remediasi tanah dilakukan dengan tahapan pengolahan tanah, pengeringan dasar tambak, perendaman, dan pembilasan; dan dilanjutkan dengan pengapuran dan pemupukan. Pengapuran tambak menggunakan dolomit dengan dosis 1,0 ton per ha. Hasil penelitian menunjukkan bahwa tambak yang diremediasi menghasilkan udang windu sebanyak 357,15 kg/ha dan tanpa remediasi sebesar 100 kg/ha. Tambak yang diremediasi pada sistem polikultur menghasilkan udang windu 100,9 kg/ha dan ikan bandeng 330 kg/ha. Penerapan teknologi remediasi dasar tanah pada budidaya udang windu sistem monokultur berdasarkan analisis ekonomi sederhana memberi keuntungan sebesar Rp26.828.500,00 /ha/siklus dan BC rasio 4,68. Polikultur udang windu dan bandeng menghasilkan keuntungan sebesar Rp8.800.000,00 /ha/siklus dan BC rasio 2,47.Remediation of acid sulfate soil pond can increase the productivity of the soil used for shrimp farming with monoculture and polyculture systems. This study was conducted to determine the post effects of soil remediation on tiger shrimp cultured in acid sulfate soil pond. The study was conducted in one of the farms owned by a fish farmer in Tempurung Island, Kasai Village, Derawan District, Berau Regency, East Kalimantan Province. The characteristics of the soil were determined to serve as the baseline information before cultivation. The pond remediation followed the procedures set by the Research Institute for Brackishwater Aquaculture and Fisheries Extension, Maros. The soil reclamation was carried out following the subsequent stages: soil plowing, pond bottom drying, inundation, and flushing; followed by liming and fertilization. Ponds liming used a dolomite dose of 1 ton/ha. The results showed that the remediated acid sulfate soil ponds could produce tiger shrimp up to 357.15 kg/ha while non-remediated ponds only produced up to of 100 kg/ha. The remediated brackish fish pond used for polyculture system could produce tiger shrimp up to 100.9 kg/ha and milkfish up to 330 kg/ha. The application of soil remediation on ponds of tiger shrimp monoculture systems yielded a profit of Rp 26,828,500.00/Ha/cycle and BC ratio of 4.68. For polyculture of tiger shrimp and milkfish, the profit was Rp 8,800,000.00/Ha/cycle and BC ratio of 2.47.

Rumput laut (Gracilaria verrucosa) telah dibudidayakan di tambak tanah sulfat masam dengan kualitas dan kuantitas produksi yang relatif tinggi. Oleh karena itu, dilakukan penelitian yang bertujuan untuk mengetahui peubah kualitas air yang mempengaruhi laju pertumbuhan rumput laut di tambak tanah sulfat masam Kecamatan Angkona Kabupaten Luwu Timur Provinsi Sulawesi Selatan. Pemeliharaan rumput laut dilakukan di 30 petak tambak  terpilih selama 6 minggu. Bibit rumput laut dengan bobot 100 g basah ditebar dalam hapa berukuran 1,0 m x 1,0 m x 1,2 m. Peubah tidak bebas yang diamati adalah laju pertumbuhan relatif, sedangkan peubah bebas adalah peubah kualitas air yang meliputi: intensitas cahaya, salinitas, suhu, pH, karbondioksida, nitrat, amonium, fosfat, dan besi. Analisis regresi berganda digunakan untuk menentukan peubah bebas yang dapat digunakan untuk memprediksi peubah tidak bebas. Hasil penelitian menunjukkan bahwa laju pertumbuhan relatif rumput laut di tambak tanah sulfat masam berkisar antara 1,52% dan 3,63%/hari dengan rata-rata 2,88% ± 0,56%/hari. Di antara 9 peubah kualitas air yang diamati ternyata hanya 5 peubah kualitas air yaitu: nitrat, salinitas, amonium, besi, dan fosfat yang mempengaruhi pertumbuhan rumput laut secara nyata. Untuk meningkatkan pertumbuhan rumput laut di tambak tanah sulfat masam Kecamatan Angkona Kabupaten Luwu Timur dapat dilakukan dengan pemberian pupuk yang mengandung nitrogen untuk meningkatkan kandungan amonium dan nitrat serta pemberian pupuk yang mengandung fosfor untuk meningkatkan kandungan fosfat sampai pada nilai tertentu, melakukan remediasi untuk menurunkan kandungan besi serta memelihara rumput laut pada salinitas air yang lebih tinggi, tetapi tidak melebihi 30 ppt.Seaweed (Gracilaria verrucosa) has been cultivated in acid sulfate soil-affected ponds with relatively high quality and quantity of seaweed production. A research has been conducted to study water quality variables that influence the growth of seaweed in acid sulfate soil-affected ponds of Angkona Sub-district East Luwu Regency South Sulawesi Province. Cultivation of seaweed was done for six weeks in 30 selected brackishwater ponds. Seeds of seaweed with weight of 100 g were stocked in hapa sized 1.0 m x 1.0 m x 1.2 m. Dependent variable that was observed was specific growth rate, whereas independent variables were water quality variables including light intensity, salinity, temperature, pH, carbondioxide, nitrate, ammonium, phosphate, and iron. Analyses of multiple regressions were used to determine the independent variables which could be used to predict the dependent variable. Research result indicated that relative growth rate of seaweed in acid sulfate soils-affected brackishwater ponds ranged from 1.52% to 3.63%/day with 2.88% ± 0.56%/day in average. Among nine observed water quality variables, only five variables namely: nitrate, salinity, ammonium, phosphate and iron influence significantly on the growth of seaweed in acid sulfate soils-affected brackishwater ponds. The growth of seaweed in acid sulfate soils-affected brackishwater ponds of Angkona District East Luwu Regency, can be improved by using nitrogen-based fertilizers to increase ammonium and nitrate contents and also fertilizers which contain phosphorus to improve phosphate content to a certain level. Pond remediation to decrease iron content and also rearing seaweed at higher salinity (but less than 30 ppt) can also be alternatives to increase the growth of seaweed.

AbstractWe constructed a mining soil restoration system combining plant, complex substrate and microbe. Sludge was added to reconstructed mine substrates (RMS) to accelerate the reclamation process. The effect of sludge on plant growth, microbial activity, soil aggregate stability, and aggregation-associated soil characteristics was monitored during 10 years of reclamation. Results show that the height and total biomass of ryegrass increases with reclamation time. Sludge amendment increases the aggregate binding agent content and soil aggregate stability. Soil organic carbon (SOC) and light-fraction SOC (LFOC) in the RMS increase by 151% and 247% compared with those of the control, respectively. A similar trend was observed for the glomalin-related soil protein (GRSP). Stable soil aggregate indexes increase until the seventh year. In short, the variables of RMS determined after 3–7 years insignificantly differ from those of the untreated sample in the tenth-year. Furthermore, significant positive correlations between the GRSP and SOC and GRSP and soil structure-related variables were observed in RMS. Biological stimulation of the SOC and GRSP accelerates the recovery of the soil structure and ecosystem function. Consequently, the plant–complex substrate–microbe ecological restoration system can be used as an effective tool in early mining soil reclamation.
