Abstract

This research was conducted at the Greenhouse Laboratory of the Faculty of Agriculture, Sebelas Maret University Surakarta, in March 2011. The aim of the study was to determine the relationship between the rainfall (synthetic) the number of elements Potassium (K) and Sodium (Na) were leached in volcanic material from the eruption of Mount Merapi. This study used artificial rainfall simulation approach  to treatment is based on the phenomenon of the eruption of Mount Merapi, Yogyakarta, Central Java by examining the leaching elements Sodium (Na) and Potassium (K) are swapped in the above-ground volcanic material Andisol. The experiments in this study using a completely randomized design (CRD) consisting of 3 to 5 treatments the sample depth artificial rain (water sprinkling) in 3 replications, namely 1 (22 mm x 1 day (22 mm)), 2 (22 mm x 10 days (220 mm)), 3 (22 mm x 20 days (440 mm)), 4 (22 mm x 30 days (660 mm)), 5 (22 mm x 45 days (990 mm)), and control ( 45 days field) with 3 replicates each. The variables measured were pH H2O, available K and Na, K and Na total, CEC, texture. Analysis of the data using the F test at the level of 95% or Kruskal-Wallis, to compare the mean between treatments using DMR test at the level of 95% or Mood Median, whereas to determine the relationship between variables used correlation test. The results showed that administration of rainfall of 22 mm / day is able to affect the leaching of potassium and sodium in the volcanic material from day 10. Leaching was significantly visible on day 30 with a decrease in available K and Na volcanic material at a depth of 0-15 cm in diameter (K 23.08%) (23.08% Na) and at a depth of 15-30 cm (K 21, 42%) (23.08% Na), and the addition of K and Na are available at a depth of >30 cm in the form of land Andisol (K 16.67%) (23.53% Na) from the previous treatment.

Abstract

The eruption of Merapi mountain has primary and secondary hazard and may damage to the land. In detail, the hazards are land degradation is a loss of some or many of germplasm and changes in plant biodiversity. The others hazard including loss of water catchment areas, the destruction of forests, and even the closing of the water source, as well as the loss of water channels. The burried of soil and soil formation inhibition were caused by the repeated eruptions of Merapi, beside the loss of roads access to agricultural land and loss of land ownerships boundaries by the eruption and cool lava. Materials of eruption are sand and pyroclastic materials, as well as the nature of cementation require special techniques and technology to use the land as new farmland. Land restoration efforts can be done with the land management by reforestation on government-owned land for water catchment function, agroforestry forage grass based, grazing field on land owned by the village and residents, with the use of organic materials in the eruption sandy soil ameliorant.

Abstract

Title : Study of Critical Soil Conservation Based on Land Unit on Sempor’s Catchment Area, Kebumen Regency. This research  aims to predict critical soil and soil erosion  level of Sempor’s  Catchment Area and to recommend the management according to soil conservation.This  is  an  explorative  descriptive  research  based  on  environment  data.  The  data  are obtained from field observation and result of laboratory analysis of soil samples taken from field survey. Furthermore, the data are classified based on critical soil classification to get critical soil map. The data also are calculated based on USLE to get soil erosion prediction. The results of soil erosion prediction are grouped based on erosion hazard levels and result of soil erosion mapping. After knowing  critical soil and soil erosion level in each land unit, recommendation  is made to manage land according to soil conservation.The result shows that on observation area with total extent 4,333.68 ha there are criticalsoil about 1,373.68  ha (31.70 %), semi critical about 2,164.54  ha (49.95 %), potentially  critical about 440.46 ha (10.16 %) and the others are about 355.00 ha (8.19 %) in the form of settlement and  reservoir  located  at  the  outside  of  the  observation  area.  The  soil  erosion  predicted  on observation area are divided into 6 classes, those are very low erosion class at about 103.90 ha (2.40 %), low erosion class at about 332.00 ha (7.66 %), moderate erosion class at about 953.78 ha (22.01 %), high erosion class at about 247.53 ha (5.71 %), very high erosion class at about 2,108.50 ha (48.65 %), acute erosion class at about 232.96 ha (5.38 %) and the others are out of observation  area. Topography  and land management  are factors that have the most dominant influence to soil erosion prediction. Total soil erosion on observation  area is about 320,958.016 tons/ha  or soil erosion average  about 74.061 tons/ha/year.  The recommendation  is to restore critical and erosion through some actions such as reboization or planting with annual crop, vegetation nursery, adding organic matter via organic fertilizer or organic mulches, making and maintaining of terrace and ditches, and agroforestry.Keywords: critical soil, erosion, Sempor,  soil coservation

Abstract

Perubahan tutupan lahan hutan mengakibatkan penurunan biomassa dan sekuestrasi karbon pada vegetasi. Penurunan biomassa dapat dipengaruhi faktor kemiringan lereng. Lereng yang curam diketahui menurunkan pertumbuhan vegetasi dan berdampak pada biomassa. Penelitian ini bertujuan untuk mengetahui pengaruh tutupan dan kemiringan lahan terhadap biomassa pohon, serasah dan karbon tersimpan serta mengetahui kadar biomassa pohon, serasah dan karbon tersimpan. Penelitian ini menggunakan metode survey dan penentuan titik pengamatan secara purposive sampling pada empat tutupan (Campuran, Mahoni, Pinus-Mahoni, Pinus) dan tiga kelas kemiringan lahan (0-15%, 15-30%, dan >30%). Estimasi biomassa menggunakan metode non-destructive dan dihitung menggunakan persamaan allometrik. Petak ukur dibuat berukuran 20 m x 20 m dengan jumlah 48 petak untuk pengamatan pohon dengan diameter ≥ 5 cm, kemudian dibuat sub petak untuk pengamatan serasah berukuran 1 m x 1 m. Hasil percobaan menunjukkan bahwa tutupan lahan Pinus menghasilkan biomassa pohon dan karbon tersimpan tertinggi bila dibandingkan dengan tutupan lahan lainnya dan variasi kemiringan menghasilkan biomassa pohon dan karbon tersimpan yang seragam atau sama. Kadar biomassa pohon dan karbon pada setiap tutupan lahan masing-masing berkisar antara 171,72–385 ton/ha dan 80,71–181,12 tonC/ha. Kadar biomassa serasah pada setiap tutupan berkisar antara 0,60–1,60 ton/ha/bulan.

Abstract

Title : Zero Point of Charge of Various Organic Fertilizer : The Effect  on Soil Cation Exchange Capacity in Degraded Lands. Zero Point of Charge (ZPC) is an important variable in describing the mechanism of reversible surface charge primarily on weathered soil dominated by variable charge. ZPC is a certain pH when the surface charge is electrically neutral or zero (pHo). The presence of organic matter effect on the nature of the charge in the soil. Research goals include: 1). Obtaining information kinds of organic fertilizer with low of pHo, 2) Knowing the behavior of pHo and net charge of soil, 3) Knowing the influence of pHo on the soil cation exchange capacity. This study is an experimental functional relationship variables approach through experiments. The experiments were conducted at Greenhouse of Agriculture Faculty, Sebelas Maret Univercity. The basic design used was completely randomized design of a single factor. The treatment is done as follows: P0 = soil without the addition of organic fertilizers, P1 = soil with the addition of cow manure 5 tons / ha, P2 = soil with the addition of chicken manure 5 tons / ha, P3 = soil with the addition of quail manure s 5 tons/ ha, P4 = soil with the addition of goat manure 5 tons / ha, P5 = soil with the addition of bokashi 5 tons / ha, P6 = soil with the addition of rice straw compost 5 tons / ha, P7 = soil by adding compost hyacinth 5 ton / ha. P8 = soil by adding compost of Titonia 5 tons / ha and each treatment was repeated 3 times. Analysis of the quality of organic fertilizers include: levels of lignin and polyphenols, C/N, pH , pHo, humic acid and fulvic acid. The soil analysis includes the C-organic soil, total N, C / N, pH , pHo, CEC. The results showed that the zero point of charge (pHo) is the lowest organic fertilizer chicken manure (4.52). Obtained a close relationship between the difference in pH H2O with pHo with cation exchange capacity. Highest cation exchange capacity achieved in the treatment of chicken manure.
