Abstract

Changes in land conditions greatly affect the life of soil macrofauna. Information about the diversity of soil fauna in rubber plantations in Labuhan village does no yet exist, so research is needed. The study aims to identify species, specifying the important value index and determine the soil fauna diversity index in rubber plantations Labuhan Village, South Batang Alai District, Hulu Sungai Tengah District. The methods used is pitfall trap by making excavtions in the ground to install plastic cups whouse position is parallel to the ground surface as many as 10 pieces and filled with 70% alcohol, the traps are closed with zinc plates with a size 20×20 cm2 installed for 1×24 hours and the hand shorting is carried out to take soil macrofauna that is inside with a depth of 20-30 cm, soil excavation using a hoe, then sorting soil macrofauna transported in the excavated soil sampel. The result of the research and identification found as many 20 species of soil fauna identified in rubber plantations with 14 families. The dominant species being the fire ant (Solenopsis invicta) with the highest important value index of 47.51%. While soil macrofauna species diversity index in rubber plantations belongs to the medium category with a value of 1.967.Perubahan kondisi lahan sangat berpengaruh terhadap kehidupan makrofauna tanah.  Informasi tentang keragaman fauna tanah di perkebunan karet di desa Labuhan belum ada, berdasarkan kondisi inilah maka kegiatan penelitian perlu dilakukan.

Abstract

The aim of study is to identify soil fauna species, its diversity index, and distributor under sengon (Paraserianthes Falcataria) and Ekaliptus (Eucalyptus Pellita) Stands. Soil fauna observatin was limited on meso and macrofauna observation on active soil fauna in sengon (Paraserianthes falcataria) And Ekaliptus (Eucalyptus pellita) Stands. The data used in this study consisted of primary data and secondary data. Observations of soil fauna in this study were limited to the mesofauna and macrofauna groups of soils. Observation of active soil fauna is carried out by the hand shorting method or by taking data or samples directly, by installing stakes with a distance of 1 x 1 meter at the sampling point and then observing the ground surface in order to know the existing of soil fauna, then continued by digging the soil at the location of the plot 15 cm deep slowly while observing the presence of soil fauna there. Research result showed that there were 22 species of soil fauna with uneven distribution and scattered throught out of the study area. The diversity of index soil fauna under sengon and ekaliptus stands are 0.8344 and 0.8636, respectively, and both relatif high. The distribution of soil fauna found at the observation site was more than the number of populations under the eucalyptus stand dominated by black ants with a population of 81 individuals and soil termites with a population of 105 individualsPenelitian ini bertujuan untuk mengidentifikasi jenis fauna tanah, indeks keanekaragamannya, dan penyebarannya di bawah tegakan sengon (Paraserianthes falcataria) dan Ekaliptus (Eucalyptus pellita). Pengamatan fauna tanah terbatas pada pengamatan meso dan makrofauna pada fauna tanah aktif di tegakan sengon (Paraserianthes falcataria) dan Ekaliptus (Eucalyptus pellita) Data untuk penelitian yang digunakan terdiri dari data primer dan data sekunder. Pengamatan fauna tanah dalam penelitian ini dibatasi pada kelompok mesofauna dan makrofauna tanah. Pengamatan fauna tanah aktif dilakukan dengan metode hand shorting atau pengambilan data atau sampel secara langsung, dengan memasang patok dengan jarak 1 x 1 meter pada titik pengambilan sampel kemudian mengamati permukaan tanah untuk mengetahui keberadaan fauna tanah, kemudian dilanjutkan dengan menggali tanah di lokasi plot sedalam 15 cm secara perlahan sambil mengamati keberadaan fauna tanah di sana. Hasil yang ditemukan pada penelitian menunjukkan bahwa terdapat 22 jenis fauna tanah dengan persebaran yang tidak merata dan tersebar di seluruh wilayah penelitian. Keanekaragaman indeks fauna tanah di bawah tegakan sengon dan ekaliptus berturut-turut adalah 0,8344 dan 0,8636, dan keduanya relatif tinggi. Sebaran fauna tanah yang ditemukan di lokasi pengamatan lebih banyak dibandingkan jumlah populasi di bawah tegakan kayu putih yang didominasi oleh semut hitam dengan populasi 81 individu dan rayap tanah dengan populasi 105 individu.

Abstract

This study aims to determine the growth of sengon seedlings in former diamond mining soil and to analyze the effect of mycorrhizal administration and the correct dosage on sengon growth. The data analysis used was using the RAL method with 5 treatments and 10 repetitions. Treatment A (without mycorrhiza), treatment B (5 grams), treatment C (10 grams), treatment D (15 grams) and treatment E (20 grams). Parameters measured were calculating the percentage of life, stem height of plant seeds, number of leaf blades and increase in diameter. The percentage of survival of sengon (Paraserianthes falcataria) seedlings on ex-diamond mining soil media was 94%. The results of the analysis of variance (ANOVA) had a very significant effect on all parameters measured, followed by using Duncan's test. Treatment E (20 grams) was very significantly different and was the best treatment from the other treatments. The increase looks very real due to the ability of mycorrhizae to accelerate the increase in height, number of leaves and stem diameterPenelitian ini bertujuan mengetahui bibit sengon dapat tumbuh pada media tanah bekas tambang intan dan menganalisis pengaruh pemberian mikoriza serta dosis yang tepat terhadap pertumbuhan sengon. Analisis data yang digunakan yaitu menggunakan metode RAL dengan 5 perlakuan dan 10 perulangan. Perlakuan A (tanpa mikoriza), perlakuan B (5 gram), perlakuan C (10 gram), perlakuan D (15 gram) dan perlakuan E (20 gram). Parameter yang diukur adalah menghitung persentase hidup, tinggi batang bibit tanaman, jumlah helaian daun dan pertambahan diameter. Persentase hidup bibit sengon (Paraserianthes falcataria) pada media tanah bekas tambang intan sebesar 94%. Hasil analisis keragaman (ANOVA) berpengaruh sangat nyata terhadap semua parameter diukur, dilanjut dengan menggunakan uji Duncan. Perlakuan E (20 gram) berbeda sangat nyata dan merupakan perlakuan terbaik dari perlakuan lainnya. Kenaikan terlihat sangat nyata dikarenakan kemampuan mikoriza yang dapat mempercepat bertambahnya tinggi, jumlah daun dan diameter batang
