Abstract

Abstrak. Sifat biofisik lahan berperan penting dalam perencanaan penggunaan lahan maupun perencanaan teknis pengelolaan lahan. Oleh sebab itu identifikasi secara cepat dan akurat sifat biofisik lahan menjadi penting. Citra radar resolusi tinggi sudah banyak digunakan untuk berbagai tujuan, antara lain untuk identifikasi tutupan lahan, analysis geologi dan analisis cuaca. Penelitian bertujuan untuk mengevaluasi penggunaaan citra RADAR resolusi tinggi untuk mengevaluasi sifat-sifat biofisik lahan sawah. Penelitian dilakukan pada areal pesawahan di Kabupaten Indramayu menggunakan citra Radarsat 2 resolusi tinggi (quad polarization) dengan empat polarisasi (HH, HV, VH, VV). Sifat-sifat biofisik lahan yang dianalisis meliputi: salinitas tanah, bobot aktual tanaman, bobot kering tanaman, tinggi tanaman, kekasaran permukaan tanah, dan kelembaban tanah. Data yang dikumpulkan dibedakan atas kelompok lahan sawah yang ditanami padi dan lahan sawah bera. Data yang digunakan terdiri dari 27 set data biofisik lahan sawah yang ditanami padi, dan 49 set data lahan sawah bera. Hasil menunjukkan bahwa dari keenam sifat biofisik lahan yang dianalisis, kelembaban tanah merupakan sifat biofisik lahan yang dideteksi lebih baik dibandingkan sifat-sifat biofisik lahan lainnya, baik dalam kondisi lahan ditanami padi maupun lahan bera. Tetapi model-model persamaan antara sifat-sifat biofisik lahan dan koefisien hamburan balik dari citra Radar resolusi tinggi ini memiliki nilai R2 yang rendah. Hal ini mengindikasikan bahwa pendugaan sifat biofisik lahan dengan nilai koefisien hamburan balik secara langsung tidak dapat digunakan pada lahan sawah.Abstract. The land biophysical properties are important in land use and technical planning in the field. Therefore, rapid and accurate identification of the land biophysical properties is an important step. In the past, the high resolution RADAR images have been used for land cover identification, weather analysis, and geological analysis. This study aims to evaluate the use RADAR images to detect biophysical properties of paddy fields. This research was carried out on paddy fields in Indramayu Regency using high resolution (quad polarization) Radarsat 2 imagery with four polarizations (HH, HV, VH, VV). The analyzed land biophysical properties included soil salinity, actual plant biomass, plant biomass (dry weight), plant height, soil surface roughness and soil moisture. The data were collected from 27 data sets of land planted with rice and 49 data sets from bare lands. The result show that of the six biophysical properties, soil moisture was the biophysical property which was detected better than the others, both on land planted with rice and bare land. But the equation models between biophysical properties and backscattering coefficient had a low R2 value. This indicates that the method to estimate soil biophysical properties using backcsaccter coefficient directly can not be applied for paddy soil.

Abstract

Limited information is available on chemical propertiesand mineralogical composition of soils in South Kalimantan Province. The objective of this study is to assess the develop derived from weathered sedimentary, granitic and ultrabasic rocks with respect to soil management. Field investigations and laboratory analyses were performed to compare morphological properties, particle sizes, mineralogical compositions of sand and clay fractions, organic C, N, pH, extractable acidity, P retention, exchangeable cations, cation exchange capacity, and oxides of iron and aluminium. The results. show the AY-14 pedon has a higher degree of development followed by MA-86 and SW-89, respectively as indicated by mineralogical composition and chemical properties. Although the three pedons are dominated by kaolinite, the AY- 14 pedon (developed from an ultrabasic rock) has no weatherable minerals and vermiculite but has high opaques, low quartz and colloid surfaces bearing positive charge. On the other hand, weatherable minerals are only found in SW-89. The MA-86 and SW-89 (developed from granitic and sedimentary rocks, respectively) have low opaques, high quartz, a minor proportion of vermiculite, and colloid surfaces bearing negative charges. These findings suggest that the AY-14 has a higher degree of development than MA-86 and SW-89. Comparison between MA-86 and SW-89 indicated that the former has lower clay cation exchange capacity (CEC) and contains no weatherable minerals indicating that the MA-86 has a higher degree of development than the SW-89. The values of exchangeable cations, CEC of soil and clay, and ECEC were low in all three pedons. The magnitude of each value was lower in the AY-14 followed by MA-86 and SW-89, respectively. In contrast, P retention and iron oxides were the highest in the AY- 14 pedon followed by MA-86 and SW-89, respectively. The three pedons have very acid to acid pH, and low C and N contents. Based on chemical properties and mineralogical composition, the three pedons need different management practices. The soil derived from ultrabasic rock (AY-14) needs higher phosphate fertilizer due to its high P retention, higher organic matter and lime than soils derived from granitic rock (MA-86) and sedimentary rock (SW-89) in order to increase CEC, nutrient availability and soil pH.

Abstract

Optimization of dry land utilization in Indonesia including in Bogor Regency is generally still has a lot of constraints. One of the causes is land degradation. At the moment, land degradation inventory is still resulting tentative acreages, since the criterion and overcome priority were different among institutions. This research aims (1) to know variables affecting level of land degradation, and (2) to compose criterion (classes range) andclassification of land degradation level in dry land both for reconnaissance and semi-detail scales based on variables affecting level of degradation. The research was conducted at three subdistricts, namely Sukamakmur, Babakan Madang and Cigudeg subdistricts. Data was collected on surveys through a case study. Biophysical data and soil samples were collected at60 key regions (derived from 3 subdistricts x 5 land critical levels x 4 replications). On each key region, undisturbed and composite soil samples were collected, altogether 60 undisturbed and 60 composite soil samples. The data were analyzed using discriminant analysis and cluster analysis. This research was resulting three criterions (range of classes) for five variables determining level of land degradation for reconnaissance and eight variables for semi-detail scales. The five variables for reconnaissance scale were type of bedrock, slope, conservation practices (P-value), silt percentage, and land use/vegetation (Cvalue). The eight variables for semi-detail scale were type of bedrock, slope, conservation practices (P-value), silt percentage, land use/vegetation (C-value), P-available, exchangeable Al, and H. This research had also generated three degradation levels for reconnaissance and semi-detail scales. The classification of land degradation for reconnaissance scale were (1) slightly degraded land (score <16), (2) moderately degraded land (score 16-39),and (3) strongly degraded land (score >39). Whilst, the classification of land degradation for semi-detail scale were (1) slightly degraded land (score <15), (2) moderately degraded land (score 15-38), and (3) strongly degraded land (score > 38).

Abstract

Many facts show that El-Niño Southern Oscillation (ENSO) phenomenon and Dipole Mode are closely related to rainfall event in Indonesia, but the magnitude of its impact varies with site. Therefore, it is needed to determine the most singnificant global climate indices that has closely related to Indonesian’s rainfall. The significant indices are able to be used in predicting rainfall in Indonesia.The objective of the present study is to detemine global climate indicators that have the significant effect to rainfall, climate/season anomaly, the occurence flood and drought in Indonesia. The study has been done through the following steps ; 1) regression analysis of rainfall with global climate indices of Sea Surface Temperatur Anomaly/SST in Nino 3.4 zone, Dipole mode Index (DMI), Southern Oscillation Index (SOI), interacton of SSTA with DMI, and interaction of SOI with DMI), 2) Plotting of rainfall anomaly and global climate indices for determining rainfall deviates with deviant of global climate forcing indices, 3) analysis of probability of exceedence for determining onset and lenght of wet season on climate extreme event, and 4) analysis impact of climate extreme event on flood and drougt occurences and damage areas of ricefield. The result showed that the closest relationship between global climate forcing indices and rainfall inIndonesia is SST in Nino 3.4 zone and only have significant relationship to rainfall in transisional season (August-November). Negative correlation between SST and rainfall indicates that the increase of SST anomaly causes the decrease of rainfall on August-November period. Probability of exceedance analysis showed that if the SST on September decrease below -0.5 -0.5 oC (indicate La-Niña event), the wet season will start earlier withlonger period. In contrast, if SST increases above 0.5 oC (indicate El-Niño event) the wet season will delay with shorter period. Impact of drought on damage of ricefield is more significant than the flood occurence.

Abstract

Abstrak: Pemanfaatan biochar asal cangkang kelapa sawit sebagai pembenah tanah memiliki potensi yang baik dalam upaya pengembangan perkebunan kelapa sawit di lahan sub optimal secara berkelanjutan. Kegiatan penelitian ini dilaksanakan untuk mempelajari pengaruh tiga tingkat dosis biochar (50; 100; dan 150 gram) yang dikombinasikan dengan 75% dosis pupuk NPK-Mg per bibit terhadap pertumbuhan bibit kelapa sawit, serapan hara, dan sekuestrasi karbon pada tahap pembibitan utama. Kegiatan lapang dilaksanakan di PT Astra Agro Lestari Tbk, Kalimantan Tengah pada bulan Maret 2015 - April 2016. Penelitian disusun dalam rancangan acak kelompok (RAK) dengan lima perlakuan dan dua puluh ulangan yaitu: (i) 100% dosis standar NPK-Mg per bibit (kontrol); (ii) 75% dosis standar NPK-Mg per bibit; (iii) 75% dosis standar NPK-Mg + 50 g biochar per bibit; (iv) 75% dosis standar NPK-Mg + 100 g biochar per bibit; dan (v) 75% dosis standar NPK-Mg + 150 g biochar per bibit. Pertumbuhan terbaik bibit kelapa sawit yang ditanam dalam media jenis tanah Lithic Hapludults diperoleh dari perlakuan 75% dosis pupuk NPK-Mg yang dikombinasikan dengan 150 gram biochar per bibit. Perlakuan ini berturut-turut meningkatkan tinggi (33,3%); jumlah daun (36,2%); diameter batang (28,9%); panjang dan lebar daun (22,6 dan 33,3%), bobot kering bibit kelapa sawit, khususnya bagian akar (65,2%), kapasitas tukar kation (17,2%), dan C-organik (26,9%). Hasil analisis terhadap perlakuan ini juga menunjukkan serapan hara N daun bibit kelapa sawit yang paling tinggi serta kadar hara P dan K yang tidak berbeda jika dibandingkan dengan perlakuan 100% dosis pupuk NPK-Mg. Atas dasar hasil tersebut maka 75% dosis pupuk NPK-Mg yang dikombinasikan dengan 150 gram biochar per bibit dapat direkomendasikan untuk digunakan pada bibit kelapa sawit.Abstract. The potential of biochar derived from oil palm kernel shell to be used as a soil amendment seems promising for sustaining oil palm plantation in marginal land. This study was conducted to investigate the effects of three biochar dosages (50; 100; and 150 gram) in combination with 75% NPK-Mg dosages per seedling on the growth of oil palm seedling, nutrient uptake and carbon sequestration in the nursery stage. A field experiment was conducted at PT Astra Agro Lestari Tbk, Central Kalimantan in March 2015- April 2016. Experiment was arranged in a completely randomized block design (CRBD) with five treatments and twenty replications i.e: (i) 100% standard dosage NPK-Mg per seed (control); (ii) 75% standard dosage NPK-Mg per seed; (iii) 75% standard dosage NPK-Mg + 50 g biochar per seed; (iv) 75% standard dosage NPK-Mg + 100 g biochar per seed; and (v) 75% standard dosage NPK-Mg + 150 g biochar per seed. The best vegetative growth performance of oil palm seedlings in Lithic Hapludults soil was shown by the application of 75% standard dosage of NPK-Mg fertilizers in combination with 150 gram biochar per seed. This treatment increased height (33.9%); leaf number (36.2%); stem diameter (28.9%); length and width of the leaf (22.6 and 33.3%), dry weight of oil palm seedlings, especially roots (65.2%), CEC (17.2%), and organic C (26.9%). This treatment also showed the highest absorption of N in leaves of oil palm seedlings, but no differences were observed for P and K uptakes compared to the treatment of 100% dosage of NPK-Mg fertilizer. On the basis of these results, the 75% dosage of NPK-Mg combined with 150 g of biochar per seed can be recommended for use on oil palm seedlings.

Abstract

Peat forests emit methane and carbon dioxide naturally. Rate of the emissions may increase if the forest is converted for other uses such as rice field. The use of mineral soil, enriched with electric furnace slag containing high level of cationic irons, as ameliorant is expected to give several benefits. Firstly, it can reduce the harmful effects of phenolic acids in the soils thereby increasing yield of rice. Secondly, it will form complex bonding that improves peat stability and reduces methane (CH4) andcarbon dioxide (CO2) emissions. This study evaluated the impact of using ameliorant in three peat soils of Central Kalimantan, i.e. inland peat at Berengbengkel, transitional peat at Sampit, and coastal peat at Samuda. The ameliorant was a combination of Ferich mineral soil (Fe2O3 =22.06%) and electric furnace slag (Fe2O3 =42.60%). The amount of ameliorant was determined based on 5% maximum adsorption of Fe3+. It was found thatinland peat soils emit more CH4 and CO2 than transitional and coastal peat soils. The use of ameliorant reduced the rate of the emission significantly. Without amelioration, total amount of carbon losses through CH4 and CO2 emission were about 2.086, 1.986, and 1.967 t ha-1yr-1 for inland, transitional, and coastal peats, respectively. Ameliorant application reduced total carbon losses in these three peat soils by about 0.597, 0.609, and 0.628 t ha-1yr-1, respectively, and also significantly the yield of rice. Based on the findings and if there was no ameliorant application, it is estimated to require 660, 1247, and 2820 years to decompose all organic carbon of inland, transitional, and coastal peat soils, respectively. Meanwhile, with ameliorant application, the time required will be about 980,1789, and 3950 years, respectively.

Abstract

Iron oxide is generaly found in the clay mineral composition of highly weathered soil (low activity clay soil) like Oxisols. There is limited information about the role of iron oxide in Oxisols, on the other hand the information is very important when we want to make use of the Oxisols. This study was done to investigate the role of iron oxide in the soilcharacteristic especially CEC, pHo, available water, plasticity index, soil color and maximum phosphate absorption. Soil samples were taken based on Soil Survey Staffs (1991), from different kinds of highly weathered soil i e: Typic Hapludox, Plinthic Hapludox and Anionic Acrudox, each sample was taken from two locations. At each location sample was taken from three different site : upper, middle and lower slope. Chemical analysis was done to determin the level of Fe.d, Fe.o, Fe.p, CEC (NH4OAc 1 M), pHo, available water, atterberg index and maximum phosphate absorption, and soil characteristics that useful for soil classification. Data were analyzed using matrix correlation test, simple and multiple regression. Principle Component Analysis was used to solve when multicolinearity problem happen. Results show that the Anionic Acrudox has the highest content of Fe.d and Fe.o, varied from 12.03 – 12.27% and1.01 – 1.12% . Followed by Typic Hapludox varied from 9.52 – 10.57% and 0.31 – 0.46% respectively for Fe.d and Fe.o. The level of Fe.d and Fe.o for Plinthic Hapludox varied from 6.31 – 9.40% and 0.09 – 0.17%. The higher the iron oxide content the lower the cation exchange capasity and the higher of the pHo. Multi regression analysis results between CEC and some soil characteristics shows that Fe.d and Fe.o can indicate thehighest variability namely 35.8%. While correlation between pHo and Fe.o shows the highest correlation and highly significant (r² = 0.65).Iron oxide has highly effect on available water and plasticity index, the higher the iron oxide content, the higher is the available water and the lower the plastisity index. The higher the iron oxide content the higher is intensity of red color of the soil. And the higher the iron oxide content, the higher is the maximum phosphate absorption; this condition is disadvantageus for plants, because the phosphate is not available for plants.

Abstract

Abstrak. Emisi CO2 terdiri atas respirasi autorof dan heterotrof. Respirasi autotrof diasumsikan tidak berpengaruh pada pemanasan global, dan sebaliknya respirasi heterotrof berdampak pada pemanasan global. Tujuan penelitian ini untuk mengukur dan mempelajari emisi CO2 autotrof dan heterotrof, yang berasal dari rizosfer dan non rizosfer tanaman kelapa sawit yang ditanam pada lahan gambut dangkal. Lokasi penelitian terletak di Rasau Jaya Umum, Kecamatan Rasau Jaya, Kabupaten Kubu Raya, Provinsi Kalimantan Barat. Emisi CO2 yang diukur dari dua belas sungkup tertutup dengan menggunakan alat analisis gas inframerah (EGM-4). Umur tanaman kelapa sawit 6 sampai 7 tahun. Pengukuran dilakukan satu bulan sekali, dari bulan Januari sampai Mei 2015. Hasil penelitian menunjukkan emisi CO2 dari rizosfer lebih tinggi dan berbeda sangat nyata dibandingkan emisi non rizosfer. Besaran emisi rizosfer dan non rizosfer diperkirakan sebesar 0,93 dan 0,44 g m-2 hr-1. Emisi bertambah besar dengan makin dalamnya muka air tanah, menunjukkan ada korelasi positif antara emisi CO2 dengan kedalaman muka air tanah.Abstract. CO2 emission consists of autotrophic and heterotrophic respirations. An autotrophic emission is not considered as negative, and in contrast, a heterotrophic oxidation of peat soils has detrimental impact on the global warming. The aim of this study is to investigate rates of emissions between autotrophic and heterotrophic respirations, generated by oil palm (Elaeis guineensis) plantation on shallow peat. The research site was located in Rasau Jaya Umum, Kubu Raya District, West Kalimantan Province, Indonesia. The ages of palms are 6 to 7 years. A total of twelve closed chambers were placed in both rhizospheres, representing autotrophic and heterotrophic oxidation, and non-rhizospheres, repsenting heterotrophic oxidation only. CO2 emissions were measured once a month, with an infrared gas analyzer (EGM-4), from January to May 2015. The results show rhizospheric emissions are significantly higher than non-rhizospheric emissions, i.e., 0.93 and 0.44 g m-2 hr-1, respectively. Values of CO2 emissions increase as water table level is low, indicating a positive correlation between water table level and CO2 emission from peats.
