Abstract

The purpose of this research was to know the effect of giving compost in sub soil (over burden) nickel mine toward chemical properties of soil and growth of sengon crop seed in an effort for introduce initial condition of the growing environment for sengon crop, so that earned seed for support revegetation activity of land ex minning.  The research was arranged in Randomized Block Design (RBD) with single factor scheme for 7 treatment degree, that is A0 (without compost), A1 (125 g compost polybag-1), A2 (250 g compost polybag-1), A3 (375 g compost polybag-1), A4 (500 g compost polybag-1), A5 (625 g compost polybag-1) and A6 (750 g compost polybag-1). The treatment reapet for 3 times so that has 21 unit tried. Every experiment unit from 9 crop so that all over has 189 crop. Variable with observed are chemical properties of soil (pH, cation exchange capacity (CEC), N-total, available P and available K) and sengon crop growing (increase high crop (cm), total leaf stalk (stalk), stem diameter (cm), ratio root tip of a leaf and index quality of seed).  The research shown that compost fertilizer giving toward chemical properties of sub soil (over burden) nickel mine raising of value for soil pH, CEC, N-total, available P and available K. However, compost giving toward sengon growth only show effect more real the increase high crop in age 45 hst. Key Word : Chemical properties of soil, compost, growth of sengon crop.

Abstract

Utilization of climatic information and physical characteristics of the soil to determine the soil water balance in agriculture is a very important factor because it relates to the planning model of activity to be undertaken. This is important because the output is known a periods of surplus and deficit water of the regions. Periods of surplus and deficit is implications for the length of growth period available to facilitate the planning of agricultural models that will be developed. The planning agricultural model is still oriented to the needs of farmers and the willingness of the government, not based on the climatic information and physical characteristics of the soil. Keywords : climatic information, soil characteristics, water balance.

Abstract

Land as an open system gives the space a dynamic process in the process of formation. Initial conditions of soil derived from a particular parent material, because the natural process leads to changes in the morphological characteristics of the soil. These conditions will further affect its use for the benefit of mankind. For that reason has conducted research on morphological characteristics and classification of land in outburst floods repeatedly in South Konawe. Research conducted by the survey grid of 50 m in an area of 70.73 ha and analyzed the physical and chemical properties, to acquire land map unit (LMU). At every LMU obtained conducted intensive observation. Three LMU generated described and each horizon soil samples were taken for analysis of physical and chemical properties. The results showed that all three Pedon were observed have a very deep to depth of solum category (> 100 cm); ground color varies; texture of clay, loam, clay loam dusty; firm consistency; angular blocky soil structure. This indicates that there has been mixing topsoil by outburst floods, however horizon B down comes from the same parent material. Soil characteristics indicate that the land is very acid reaction to acid, available nutrients (N, P and K) and exchangeable base cations, cation exchange capacity (CEC) is very low to low, base saturation (BS) is very low to moderate. This soil is classified in the great group as Dystrudepts, Hapluduts and Hapluduts.   Keywords:  vharacteristic, morphology, classification,  and land outburst floods

Abstract

The objective of this study was to evaluate the variations of twelve chemical elements (Ni, Fe, Co, Mg, Mn, Al, Si, Zn, Ti, P, Ca and Cr) in laterite soil profiles from Wantulasi area in South East Sulawesi Province of Indonesia. Eighty four (84) samples of three profiles (i.e. each profile consists of eight samples) had been used to study their variations in soil using  the X-Ray Fluorescence (XRF). Results analysis of the chemical elements content in three profile using XRF indicated that there were good correlationsbetween the chemical elements in the soil profile with the significant correlations were found in Ni and Fe, Ni and Si, Ti and P, Fe and Al, and Co and Mn, respectively. On the other hand,the results of study showed that the variations of the chemical elements could be related to the enrichment and translocation of the elements  in soil profile and also their possibilities to be related with a given chemical elements in soil profile. Therefore, we suggest that the observed patterns in chemical elements with a good correlation in laterite profile can be used as proxies to integrate the evaluation of the chemical and physical weathering process based on the elements characteristics in soil profiles.

Abstract

The composition of the soil fauna community have played an important role in regulating decomposition and nutrient cycling in agro-ecosystems (include cocoa plantation). Changes in food availability and conditions in the soil habitat can affected the abundance and diversity of soil fauna. This study aimed: (i) to analyze the pattern of changes in soil fauna community composition and characteristic of soil habitat based on the age increasing of cocoa plantation, and (ii) to identify taxa of soil fauna and factors of soil habitat which differentiate among the cocoa plantations. Sampling of soil, roots and soil fauna was conducted from cocoa plantation aged 4, 5, 7, 10, and 16years. Difference in composition of the soil fauna community between ages of the cocoa plantation is significant. Profile of soil habitats was differ significantly between the cocoa plantations, except 5 and 7 years aged. A group of soil fauna has relatively limited in its movement, and sensitively to changes in temperature, soil acidity, and the availability of food and nitrogen are taxa differentiating between soil fauna communities. Soil physic-chemical conditions that affect metabolic activity, movement, and the availability of food for soil fauna is a  distinguishing factor of the characteristics of the soil habitat between different ages of smallholder cocoa plantations.Keywords: Abundance, arthropod, composition, nematodes[How to Cite: Kilowasid LMH, TS Syamsudin, F X Susilo, E Sulistyawati and H Syaf. 2013.Characteristics of Soil Fauna Communities and Habitat in Small-Holder Cocoa Plantation in South Konawe.

Abstract

Tanaman kakao merupakan salah satu komoditas utama penghasil devisa negara. Kakao berkembang hampir di seluruh Indonesia, termasuk Kabupaten Kolaka sebagai salah satu daerah penghasil. Keberadaannya saat ini telah memunculkan banyak masalah dari pertumbuhan hingga produksi. Masalah tersebut selain hamadan penyakit juga tanaman rata-rata telah berumur lanjut berusia di atas 18 tahun. Usia ini menyebabkan produktivitas semakin menurun. Untuk mengantisipasi lebih awal penurunan produksi tersebut, maka telahdilakukan  penelitian  selama  10  bulan  untuk  mengevaluasi  hubungan  kualitas  lahan,  pertumbuhan  dan produksi kakao berumur lanjut di Kabupaten Kolaka Timur, Provinsi Sulawesi Tenggara. Metode surveiyang digunakan dalam penelitian ini dengan 92 Satuan Pengamatan Lahan (SPL) dan 27 parameter sifat tanah. Hasil penelitian menunjukkan bahwa kualitas perkembangan tanah dengan karakteristik tingkat pelapukan berhubungan dengan produksi kakao. Kualitas sifat fisik khususnya karakteristik kedalamanefektif dan permeabilitas berkorelasi nyata dengan produksi kakao. Hubungan kualitas sifat kimia dengan produksi kakao menunjukkan bahwa pH (H2O), C-organik, dan P2O5  berkorelasi positif dengan produksi tanaman, sebaliknya kejenuhan Al berkorelasi negatif. Kata kunci : Kualitas lahan, karakteristik tanah, produksi dan kakao.

Abstract

Forest fires are one of the environmental problems that recur almost every year in Indonesia. This problem if not handled properly will certainly cause various negative impacts such as the emergence of haze that can interfere with public health and reduced forest cover, in forest areas. Taman Hutan Raya Nipa-Nipa (Tahura) as one of the Natural Preservation areas of Southeast Sulawesi Province is also inseparable from the problem of forest fires. The aims of the study were to analyze the level of forest fire vulnerability in the Tahura Nipa-Nipa area, especially in Watu-Watu Village, West Kendari Subdistrict, and the variables that most affect the level of forest fire vulnerability. Data analysis based on the weighting of each element is then carried out the determination of the vulnerability class using equations: forest fire vulnerability = {30 % x (land cover)} + {(20 % x height of place)} + {(20 % x Rainfall)} + {(10 % x distance from road)} + {(10 % x distance from river)} + {(10 % x distance from settlement)}. Mapping the class of forest fire vulnerability areas using geoprocessing with input data on land cover, place height, rainfall, and distance from roads, rivers, and settlements. Then an analysis is carried out and will be selected data according to the score of the level of forest fire vulnerability, namely very low/not a vulnerability with a score of 5, low with a score of 4, medium with a score of 3, high with a score of 2, very high /very vulnerability with a score of 1. The results showed that the level of forest fire vulnerability in Tahura Nipa-Nipa has 3 levels, namely the level of high forest fire vulnerability with an area of 68.51 ha, the level of moderate forest fire vulnerability with an area of 62.29 ha, and the level of low fire vulnerability with an area of 143.35 ha. The variables that most affect the level of forest fire vulnerability at the research site are land cover and community accessibility distance in the form of distance from the road and distance from the settlement.  Keywords: fire vulnerability, forest fire, Tahura Nipa-Nipa, Kendari

Abstract

Pertambahan penduduk sejatinya harus juga dibarengi dengan pertambahan jumlah produksi untuk menjaga agar kebutuhan pangan masyarakat tetap terjaga. Penelitian ini dilaksanakan dengan maksud untuk mengevaluasi kesesuaian lahan serta menentukan alternatif perencanaan penggunaan lahan untuk pengembangan tanaman jagung, ubi kayu dan kacang tanah di Kecamatan Poleang Timur. Penelitian ini menggunakan metode survei bebas didasarkan pada unit lahan. Prosedur pelaksanaan survei tanah dilaksanakan dalam beberapa tahap meliputi tahap persiapan, tahap operasi lapangan dan tahap analisis sampel di laboratorium. Perencanaan penggunaan lahan dilakukan berdasarkan evaluasi kemampuan lahan dan besarnya bahaya erosi. Hasil penelitian menunjukkan bahwa pengembangan tanaman pangan di Kecamatan Poleang Timur Kabupaten Bombana sesuai untuk dikembangkan khususnya jagung seluas 5271,29 ha (78,04%), ubi kayu seluas 4872,34 ha (72,14%) dan kacang tanah seluas 5020,77 ha (74,33%). Alternatif arahan pengelolaan lahan untuk pengembangan tanaman pangan khususnya jagung, ubi kayu dan kacang tanah di Kecamatan Poleang Timur Kabupaten Bombana dilakukan pada tingkat sedang berupa pemupukan untuk faktor penghambat ketersediaan hara, penambahan bahan organik dan pengapuran untuk perbaikan faktor penghambat retensi hara, bahaya erosi diatasi dengan usaha konservasi tanah seperti penanaman sesuai kontur, pembuatan teras dan penanaman tanaman penutup tanah, pembuatan saluran irigasi/pengairan untuk penghambat ketersediaan air. Diharapkan dengan adanya penelitian ini mampu memberikan sumbangsih pemikiran dan sebagai bahan pertimbangan untuk pemerintah daerah setempat dalam hal penyusunan kebijakan serta untuk masyarakat dalam usaha pengembangan tanaman pangan.

Abstract

ABSTRACT The transmigration paradigm changed from central to regional government policies. Meanwhile, the current condition of land for proper transmigration is very difficult to obtain, so it is shifting towards forest areas. The purpose of this study is to analyze changes in the structure of the RTSP space so that the condition of protected forests and buffer areas is well maintained and sustainable. This study used the current RTPS location comparison survey method and the results of future RTSP analysis. The results obtained (a) the measured area of UPT Tongauna is 1,040.49 and the area that can be used for transmigration settlement land covering an area of 200 ha which can accommodate as many as 100 households with the TPLK pattern; (2) to maintain forest sustainability, there is a change in the Border or Buffer Zone of the RTSP location and forest area from 100 Ha to 553 Ha; and (3) the transfer of the LU II location which was originally located in the Production Forest Area (HP) after an analysis, the transfer of the kapling/parcel to the new spatial location was carried out. In an effort to avoid environmental damage, land clearing should use more manual systems to avoid excessive land and forest use.Keywords: RTSP, Transmigration, UPT.

Sementara kondisi lahan untuk transmigrasi yang layak saat ini sangat sulit diperoleh, sehingga bergeser ke arah kawasan hutan. Tujuan penelitian ini adalah  untuk menganalisis perubahan struktur ruang RTSP agar kondisi hutan lindung dan kawasan penyangga terjaga dengan baik dan berkelanjutan. Penelitian ini menggunakan metode survei perbandingan lokasi RTPS saat ini dan hasil analisis RTSP ke depan. Hasil yang diperoleh (a) luas terukur UPT. Tongauna adalah 1.040,49 dan Luasan areal yang dapat dimanfaatkan untuk lahan permukiman transmigrasi seluas 200 Ha yang dapat menampung sebanyak 100 KK dengan pola TPLK; (2) untuk menjaga kelestaria hutan maka terjadi perubahan Sempadan atau Buffer Zone lokasi RTSP dan Kawasan hutan dari 100 Ha menjadi 553 Ha; dan (3) pemindahan lokasi LU II yang semula terletak dalam Kawasan Hutan Produksi (HP) setelah dilakukan analisis maka dilakukan pemindahan kapling/persil pada lokasi tata ruang yang baru. dalam upaya untuk menghindari kerusakan lingkungan maka pembukaan lahan sebaiknya lebih banyak menggunakan sistim manual untuk menghindari pemanfaatan lahan dan hutan yang berlebihan.Kata Kunci: RTSP, Transmigrasi, UPT.
