Abstract

Penggunaan lahan merupakan hasil dari intervensi (campur tangan) manusia terhadap lahan dalam rangka memenuhi kebutuhan hidup baik materiil maupun spiritual dan mengalami perubahan sejalan dengan meningkatnya jumlah dan aktivitas penduduk dalam menjalankan kehidupan ekonomi, sosial dan budaya. Pola penggunaan lahan di Kabupaten Kubu Raya dan Sanggau selama tiga dekade mengalami perubahan yang signifikan. Tutupan lahan hutan Kubu Raya pada dekade 1970-an masih 100%, kemudian mulai dekade berikutnya sampai tahun 1991 mulai banyak dibuka untuk perkebunan rakyat dan perkebunan besar maupun perkebunan campuran. Sementara itu, di Kabupaten Sanggau dalam periode 1996-2005 perubahan tutupan lahan hutan dan wanatani menurun secara signifikan, yang diikuti dengan meningkatnya perkebunan. Tujuan penelitian ini adalah untuk mengidentifikasi perubahan penggunaan/penutupan lahan di Kabupaten Kubu Raya dan Sanggau dan mengetahui perkembangan perkebunan sawit yang terjadi selama tahun 1990-2013. Data spasial penggunaan/penutupan lahan diperoleh dari Kementrian Kehutanan, kemudian dicermati ulang menggunakan citra satelit Landsat dengan Sistem Klasifikasi Penutupan Lahan Kementerian Kehutanan (SNI 7654:2010). Selama periode 1990-2013, perubahan penggunaan lahan terjadi secara dinamis. Penggunaan/penutupan lahan hutan secara konsisten menurun sedangkan penggunaan/penutupan non-hutan: lahan terbuka, semak belukar, semak belukar rawa, dan kebun sawit relatif meningkat. Secara umum, luas perkebunan sawit di Kabupaten Sanggau meningkat yang sebagian besar berasal dari konversi penggunaan lahan non-hutan. Pada periode 1990-2009 luas penggunaan lahan sawit bertambah dari penggunaan lahan hutan rawa sekunder sedangkan pada periode 2009-2013 dari lahan non-hutan. Kata kunci: Perubahan penggunaan/penutupan lahan, perkebunan kelapa sawit

Abstract

The nutrient status evaluation model plus one test is carried out to determine which nutrients are the limiting factor. This model needs to be validated both statistically and agronomically of plant growth and production, so the results can be interpreted appropriately. This study aimed to statistically validate the nutrient status of the model plus one test, evaluate the effect of fertilizer treatment on the growth and production of maize, and the correlation of available soil nutrients with plant nutrients. The experiment was conducted at the Cikabayan Farm, Dramaga Bogor. The experiment used a plus one test treatment design which included: (1) Control, (2) N, (3) N + P, (4) N + P + K, (5) N + P + K + Ca, (6) N + P + K + Ca + Mg, and (7) N + P + K + Ca + Mg + S. Fertilizers used are Urea (N), SP-36 (P), KCl (K), agricultural lime (Ca) ), MgO (Mg), and ZA (S). The environmental design used a randomized block design of 2 replications to obtain 14 experimental units. The results showed that the nutrient of the limiting factor was Ca. This is evident from the results of the variance which showed that the addition of Ca nutrient treatment significantly affected the growth and production of maize. Correlation of exchangeable Ca with crop Ca nutrient content was higher than other nutrients (correlation coefficient / r = 0.75), and classified as very significant. In leaf color reflectant was found that red and green color reflectant was influenced by K nutrient treatment, blue color reflectant by P and Ca nutrients, green and blue color reflectant by Mg nutrient treatment, while blue and red color reflectant by N and S. Nutrient treatment results from nutrient status is used for further fertilization actions.

Abstract

Pupuk urea merupakan sumber hara nitrogen (N) yang paling banyak digunakan di Indonesia, termasuk pada lahan sawah. Urea merupakan pupuk N yang larut air sehingga penggunaan urea di sawah perlu dikaji dalam hubungannya dengan pelepasan pupuk. Di dalam penelitian ini digunakan urea dengan formulasi berbeda yaitu pupuk urea Kujang dan Pupuk Sriwijaya (Pusri) yang merupakan urea konvensional dan urea prill dan granul yang merupakan urea modifikasi yang mengandung formaldehida masing-masing 0.10 dan 0.50%. Tujuan penelitian ini adalah untuk mengevaluasi pelepasan N dari tipe urea konvensional dan urea yang diberi formaldehida pada kondisi tanah tergenang. Metode penelitian yang digunakan adalah inkubasi dan pencucian. Inkubasi dilakukan selama 7, 14, 28, 45, 60, dan 90 hari serta dilakukan pencucian pada setiap akhir masa inkubasi. Hasil pencucian ditetapkan kandungan amonium dan nitrat. Hasil penelitian menunjukkan bahwa pelepasan N dalam bentuk amonium dan nitrat antar perlakuan pupuk urea tidak berbeda nyata. Hasil total N tercuci menunjukkan nilai paling tinggi diperoleh oleh urea granul sebesar 78.0 mg tabung-1, kemudian disusul oleh urea prill 75.2 mg tabung-1, urea kujang sebesar 71.5 mg tabung-1, dan urea pusri sebesar 68.4 mg tabung-1. Berdasarkan hasil persamaan first order kinetic, diperoleh nilai pelepasan maksimum dan konstanta kecepatan. Nilai pelepasan maksimum tertinggi dimiliki oleh urea granul sebesar 94.6 mg tabung-1, kemudian urea prill sebesar 88.3 mg tabung-1, urea Pusri sebesar 82.3 mg tabung-1, dan urea Kujang sebesar 79.2 mg tabung-1. Sementara untuk nilai konstanta kecepatan, konstanta kecepatan tertinggi diperoleh pada urea kujang sebesar 0.0349 hari-1, kemudian dilanjutkan oleh urea prill dan pusri sebesar 0.0256 hari-1, dan urea granul sebesar 0.0253 hari-1. Hasil penelitian menunjukkan bahwa urea yang diperlakukan dengan formaldehida terutama dalam bentuk granul cenderung memiliki kemampuan untuk memperlambat proses pelepasan N yang ditunjukkan dengan nilai konstanta kecepatan pelepasan N yang paling rendah.

Abstract

Productivity of pepper in Bangka Belitung Province has decreased because one of the causes is the problem of the low nutrient availability. The research was conducted in Bangka Belitung Province to determine the distribution of pH, exchangeable aluminium (Exch Al), and available phosphorus (P) and the correlation among those parameters. Soil samples at depths of 0-30 cm and 30-60 cm were collected at the specified points on a 1: 250,000 scale land system map. The pH was determined by shaking the soil sample with distilled water and the ratio of soil sample and distilled water was 1:5. Exch Al was extracted using 1.00 mol L-1 KCl and determined by titration. Available P was determined using the Bray 1 method. Basic statistic analyses to have minimum, maximum, average and standar deviation (SD) values were conducted. Correlation test among pH, exch Al, and available P to evaluate their relationship were also conducted. The results showed that soils in Bangka Belitung were relatively acid, relatively high exch Al especially in the depth of 0-30 cm and relatively low available P as Bray 1-P. Bray 1-P and exch Al on the depth of 0-30 cm had higher SD than that of the other paramaters. As for correlation analyses, pH significantly negatively correlated with exch Al. pH and exch Al did not correlate with Bray 1-P. This research suggested that soil in Bangka Belitung had problem with soil acidity and low amount of available P in the form of Bray 1-P. The amount of Bray 1-P did not correlate with the amount of exch Al.

Abstract

Amending Ultisols using organic matter encourages a paramount improvement in its chemistry and fertility characteristics. This study was aimed to evaluate the changes in soil chemical properties due to the animal manure amelioration in Ultisol in the Jasinga, Bogor, West Java, using classical and advanced statistical methods. Composite soil samples were collected then incubated with three types of animal manure (cow, chicken, and goat) and four rate levels (0, 2.5, 5, and 7.5% of dry weight). The dynamics of eleven soil variables (pH, organic C, total N, cation exchange complex/CEC, base saturation/BS, and exchangeable Al, H, Ca, Mg, K, and Na) were observed four times (0, 2, 4, and 6 weeks). Basic cation saturation ratio/BCSR and sufficiency level of available nutrients/SLAN soil fertility approaches were applied. Modeling comparison was done among multiple linear regression/MLR, machine learning/ML (tree regression/TR, random forest/RF, gradient boosting machine/GBM), and deep learning/DL (multilayer perceptron/MLP). Most of the soil chemical and fertility parameters exhibited strong relation among three applied factors. Generally, their values failed to reach the BCSR’s ideal soil and national SLAN’s sufficiency criteria; oppositely, they were categorized as sufficient based on the global SLAN approach. Multivariate analysis revealed the similarity among manure type and rate, whereas incubation time showed the opposite trend. MLR usage was convenient in modeling BS, pH H2O, and Al saturation. Meanwhile, CEC modeling requires more sophisticated methods. This study highlighted the possible improvement of Ultisol chemical properties and fertility characteristics by amending it with a higher rate and low C/N ratio of animal manure, and using ML to capture non-linear relationships in soil.

Abstract

Generally, Nickel mining was conducted by the open-pit mining method which caused change of soil physical, chemical and biological properties. Reclamation land often experienced various obstacles, including microclimate conditions that were not yet suitable, overburden chemical, physical and biological properties, difficulty in obtained ameliorant, and lack of topsoil. Topsoil that was used for post-mining reclamation land activities was obtained from the soil is not yet mined locations (natural soil). This study was aimed to determine differences in soil characteristics (soil physical, chemical and biological properties) on post-mining reclamation land with natural soil without topsoil. The research used survey methods conducted on post-mining land of PT. INCO. Soil samples were taken at 2 locations, namely, the location of post-mining reclamation (Harapan) and location that had not mined but the topsoil had peeled to a depth of ± 1 meter (Shelly). The results showed that the soil physical and biological properties at Shelly location were relatively better than those at Harapan location. The soil at Harapan and Shelly locations had available P content and exchangeable-Na was low and exchangeable-Ca was very low. Exchangeable-Mg was high at Harapan, while at Shelly was low-moderate. The exchangeable-K content of the soil in the Harapan location was moderate than Shelly location. The soil at Harapan location had a very high Base Saturation (BS) with a pH of 6.7 than Shelly location had high BS with a pH of 5.8. It is necessary to improve post-mining reclamation land management.

Abstract

Conventional soil analyses are time-consuming; therefore, the soil quick test (QT) method is needed. This study was to assess the accuracy of soil pH, N-nitrate, available phosphorus (P), and exchangeable potassium (K) analysis determined by the QT method developed by Akvo and calibrated with standard laboratory methods. The field research collected 131 soil samples, collected from horticultural lands in 4 regencies within East Java-Indonesia, started from February to August 2017. Soil analysis measured were soil pH, N-nitrate, available P, exchangeable K, textures, organic C, and CEC. The colorimetric-based QT method was performed on the soil sample extracted by Mehlich 1, and the color was developed by dipping strip test paper in supporting chemical solutions. A smartphone camera was used for the reading, and the results were directly displayed on the smartphone screen. The QT method’s calibration models were created by stepwise multiple linear regression involving the correlated soil chemical properties. The values of calibrated QT method (i.e. soil pH, N-nitrate, and available P) showed significant correlations with the values from the laboratory. However, the results suggested that the QT method developed by Akvo could be used for nitrate due to having a relatively high correlation with that of standard laboratory.

Abstract

Nowadays, halting greenhouse gasses (GHG) emission is the world's major concern to mitigate global climate change. In oil palm cultivated tropical peatland, GHG emission is primarily constituted of CO2 flux emitted from aerobic heterotrophic respiration (Rh), the natural degradation process of organic material in an oxidative environment. By coupling descriptive and predictive statistical approaches, this study attempt to gain an in-depth understanding of the effects of zeolite rates and incubation time on CO2 emission that came from aerobic Rh in peat, as well as their decomposition process. This study found that zeolite amelioration up to 30% of the peat at field capacity and starting from the first month of observation (month-1) significantly restricted peat Rh, denoted by a reduced amount of observed CO2 flux (0.021 and 0.019-0.012 mg m-2 sec-1, respectively). Both factors and several soil variables exhibited some non-linear relationships with Rh at different magnitudes and importance, showing the limitation of the traditional linear-based approach to interpreting their complex interrelationships, as well as predicting CO2 flux. This study highlights the vital role of a polynomial (GAM) and artificial intelligence (Cubist and GBM) -based pedotransfer models in improving our understanding regarding the dynamic of the peat decomposition process as affected by zeolite amendment.

Abstract

Determining the oil palm dead roots contribution to total (Rt) and heterotrophic (Rh) respiration as a source of greenhouse gas/GHG emission in tropical peatland is urgently required, as well as predicting their magnitude to cope with difficulties of direct in-situ measurement. This study is designed to simulate the CO2 flux emitted from oil palm dead roots/Rdr in tropical peatland as affected by water content/WC and residence time/RT. The dead oil palm roots were cleaned, treated with control/15, 100, 150, 300, and 450%WC, and then incubated for three months. CO2 flux measurement, C, N, and CN ratio determination were conducted every month. This study demonstrated the importance Rdr among other CO2 emission sources, ranging from 0.05-2.3 Mg CO2 ha-1 year-1 with an average of 0.7 Mg CO2 ha-1 year-1. Rdr contribution for literature Rt and Rh were around 0.3 to 1.3 and 0.9 to 3.5%, respectively. As a product of microbial respiration, Rdr was affected by WC and RT, supported by analysis of variance, linear mixed effect model/REML, and multivariate analysis. 100-150%WC resulting in significant and highest Rdr, whereas the increase (300-450%WC) or decrease (15%WC) would generate lower emission. Rdr culminated in the first month after incubation; meanwhile, it declined in the following months. This study also emphasized non-linear relationships between CO2 flux and other root properties, which can be modeled conveniently using non-linear approach, particularly using polynomial and artificial intelligence-based models. The simulation presented in this study served as an initial attempt to separate Rdr from Rh, as well as to predict CO2 flux with reasonable accuracy and interpretable methods.
