Abstract

Soil microarthropods is a arthropods that have an important role in decomposing organic materials and soil nutrients. On the farmland there is organic materials content and soil nutrients that abundants enough, because the addition of manure as a source of energy in the ground. The research was conducted in August-October 2015 took place in the field of organic and inorganic farmland in the Batur Village, Getasan Sub-district, Salatiga. This study aimed to examine the soil microarthropods community structure in organic and inorganic farmland as well as the effect of chemical and physical environmental factors to community structure of soil microarthropods. The study was conducted with samples of soil sampling method (PCT) and extracted using Barlese Funnel Extractor. Statistically show that diversity of soil microarthropods between organic and inorganic farmland are not significantly different. There is found 28 taxa of soil microarthropods in organic farmland and 23 taxa in inorganic. The highest total individual density of the taxa are exist in the organic farmland (2260 individual/ m²). The highest abundance of soil microarthropods taxa in inorganic farmland are Carabidae (26,55%) dan Prostigmata (13,27%), while in inorganic farmland are Carabidae (17,24%) dan larva Coleoptera (13,79%). The evenness of soil microarthropods taxa in organic farmland are much low compared with inorganicfarmland, because there is a dominant taxa (Carabidae). There is an influence relation between the chemical and physical environmental factors including water content, porosity, nutrient, and organic materials with community structure of soil microarthropods. Key words:Community structure, Soil microarthropods, Organic and inorganic farmland

Abstract

Water media influences the effectiveness of the use of ovitrap media for Ae. aegypti. Water media which is prefered by the mosquito as well as inhibition the premature growth have huge potency in controlling Ae. aegypti. The objective of this study were to investigate the preference of oviposition of Ae. Aegypti and to determine the premature growth of Ae. aegypti in water media containing a combination of organic matter and different chlorine concentrations, also to examine the interaction between organic matter and chlorine to the preferences of oviposition and the premature growth of Ae. Aegypti. The method of this study is done by experiment by applying Completely Randomize Design (RAL). This study used two types of water media combination. The media combinations contained organic materials and chlorine with seven different treatments. They were well water (control), water added with soil and hay-soaked water added with chlorine by 5, 10, and 15 ppm respectively. The findings show that Ae. aegypti have the tendency in choosing hay-soaked water in lay the eggs since it has abundant content of organic matter in it. The mean amount of Ae. aegypti oviposition in the water medium combination ranged from 84 to 152.7 eggs, while the percentage of premature survival rate ranged from 59.4% to 97%. In conclusion, the study showed that the preference of oviposition is highly influenced by the organic matter content of the media. Both organic matter and chlorine do not inhibit the premature growth of Ae. aegypti. However, the interaction between organic matter and chlorine to the preferences of oviposition and the premature growth of Ae. aegypti was not found. Keywords: Aedes aegypti, combination, ovitrap, organic matter, chlorine.

Abstract

Mangrove is a plant that has the morphological and physiological adaptations to habitats which influenced by a tide. This plant can grow and develop in an environment of high salinity and its soil conditions are less stable and aerobic. Litter mangrove is the main source for the availability of detritus and is the largest component constituent of a food web in a mangrove ecosystem environment. Algae epiphytic microalgae is a group that lives attached to the plant, including the mangrove litter. The study aims to assess the abundance and diversity of epiphytic algae on different types of mangrove leaf litter. The observed mangroves leaf litter were Avicennia alba, Sonneratia sp. and Rhizophora sp. Epiphytic algae were brushed on mangrove leaf litter covering an area of 6.25 cm2 and diluted with distilled water. Samples were observed under a microscope with a magnification of 400 x. Water quality parameters were measured in situ and the organic ingredients, total N and P were analyzed. The results showed that epiphytic algae on each type of mangrove leaf litter were not different. Rhizophora sp is the most abundant and the richest species compared with other types of litter that are equal to 622 individuals / cm2 and 26 species of epiphytic algae. While the abundance of Avicennia alba and Sonneratia sp were 459 ind/cm2 and 321 ind /cm2, in the coastal mangrove areas of Morodemak was found 28 species of epiphytic algae. The common epiphytic algae species found in all types of mangrove litter were Cymbella sp., Coscinodiscus sp., and Synedra ulna. In general, the group of Bacillariophyta (diatoms) is the dominant species in some mangrove leaf.

Abstract

The choice of using pesticides with natural ingredients or synthetic chemicals is a differentiator between organic farming systems and inorganic farming systems. Pesticides are additives in agriculture to control pests or weeds. Abamectin is one of the active ingredients that can be found in pesticides. Ground microarthropods are members of the soil mesofauna, which are soil animals that have a body size ranging from 0.2-2 mm. The purpose of this study was to determine the effect of differences in the application of pesticides on a field or laboratory scale on the structure of soil microarthropod communities. Soil samples were taken from three agricultural lands, namely Bandungan inorganic agricultural land, Kopeng inorganic agricultural land and Kopeng organic agricultural land. The study was conducted in August to December 2018 in the Ecology and Biosystematic Laboratory of the Department of Biology, FSM Undip. Found a total of 60 species species richness originating from 13 orders. The application of pesticides which include the concentration and frequency of pesticide spraying has a negative influence on the structure of soil microarthopod communities. Application of abamectin pesticides on a laboratory scale proves that the administration of abamectin pesticides that exceeds the recommended concentration will adversely affect the structure of the soil microathropod community. Based on statistical tests of soil microarthropod species diversity from the results of the application of pesticides on a field and laboratory scale is significantly different.

Abstract

Peran mikroorganisme dan fauna tanah dalam menentukan kualitas tanah telah diketahui cukup luas, namun perannya terhadap kapasitas infiltrasi air belum banyak dikaji. Penelitian ini secara umum bertujuan untuk mengetahui pengaruh biostarter berupa inokulan mikroba komersial untuk perbaikan kualitas tanah. Secara khusus penelitian ini bertujuan untuk mengetahui pengaruh produk biostarter terhadap struktur komunitas mesofauna tanah dan laju infiltrasi air serta korelasi antara struktur komunitas mesofauna tanah dengan kapasitas infiltrasi. Penelitian ini menggunakan Rancangan Acak Lengkap faktor tunggal dengan empat perlakuan biostarter yaitu EM4, Bioklin, Mig Dec, dan Orgadec. Periode sampling dilakukan dua kali pada hari ke 30 dan hari ke 50 inkubasi. Hasil penelitian menunjukkan bahwa penambahan biostarter memengaruhi struktur komunitas mesofauna tanah, khususnya berpengaruh positif terhadap kelimpahan Oribatida dan Mesostigmata. Produk Orgadec secara konsisten mampu meningkatkan kelimpahan mesofauna tanah paling tinggi pada  30 hari maupun 50 hari. Laju infiltrasi pada umur inkubasi 30 hari menunjukkan adanya perbedaan yang nyata pada perlakuan Orgadec saja, sedangkan pada umur 50 hari, perbedaan secara nyata ditunjukkan pada perlakuan EM4, Mig Dec dan Orgadec. Secara statistik, total kelimpahan mesofauna tanah dan kelimpahan Oribatida menunjukkan perbedaan yang nyata dengan laju infiltrasi.   Keywords: biostarter, struktur komunitas, mesofauna tanah, laju infiltrasi
