Abstract

Penduduk dan area permukiman dalam kota Kendari mengalami pertumbuhan cepat. Hal ini diikuti produksi sampah rumah tangga baik organik maupun anorganik. Limbah-limbah ini memiliki potensi ekonomi melalui pemanfaatannya sebagai sumber pupuk organik dalam usaha tani tanaman sayuran skala rumah tangga, khususnya dalam area tempat pembuangan akhir sampah (TPAS). Pengetahuan dan keterampilan penduduk yang bermukim dalam dan sekitar area TPAS masih terbatas dalam mengkonversi limbah-limbah tersebut sebagai pupuk organik, dan teknik aplikasinya dalam budidaya tanaman pada lahan pekarangan dan sempit. Kegiatan pengabdian kepada masyarakat ini ditujukan untuk (i) meningkatkan kemampuan masyarakat terhadap pembuatan biochar dari limbah kayu dan plastik serta penggunaannya sebagai pembenah tanah, dan (ii) meningkatkan pengetahuan dan ketrampilan petani dalam pemanfaatan lindi sebagai pupuk organik cair. Kegiatan pengabdian melalui integrasi KKN-Tematik mampu mempercepat penerimaan pengetahuan dan keterampilan masyarakat dalam area TPAS Puuwatu terkait teknik untuk memanfatkan limbah plastik, potongan kayu, dan lindi sebagai pupuk organik dalam budiddaya tanaman dengan sistem pot menggunakan media tumbuh dari tanah marginal, dan sistem hidroponik menggunakan lindi sebagai media tumbuh. Kegiatan pengabdian ini juga memperkenalkan teknik menghasilkan bahan bakar sebagai produk ikutan dalam selama pirolisis limbah plastik serta metode dalam penanganan sampah plastik, kayu dan lindi untuk keperluan budidaya tanaman pekarangan dan produk ikutan lainnya (khsusnya bahan bakar) dalam pembuatan biochar berbahan baku limbah plastik kepada instansi terkait dan pihak pengelola TPAS Puuwatu.

Abstract

Earthworms have the ability in modifying soil biological quality for plant growth. Their ability is mostly depending on its ecological groups. The objectives of the research were to study the influence of two ecological groups of earthworms on soil microbial activity and soil micro-fauna abundance, and to know the potential of soil modified by earthworms as plant growth medium. Eight combination of individual earthworm from epigeic and endogeic groups was applied into pot  that was filled by soil from two years of  nickel stockpile and each treatment was repeated by five times. The experiment was following complete randomize design procedure. After sixteen days of research, the soil sample from each pot was analyzed for soil FDA activity, number of flagellate and nematodes. Furthermore, one kg of the soil from each pot was taken and every pot was grown by Paraserianthes falcataria seedling with the age of five days and continued its growth for two months. The results indicated that the soil FDA activity, number of flagellate and nematodes among treatments were significantly differences. In addition, it indicated the significant differences in dry weight of shoot, root, total plant, and root to shoot ratio of P. falcataria seedlings. It concluded that the combination of an individual number of epigeic and endogeic earthworms improved soil biological quality of stock pile, amd  most suitable for seedlings growth in nickel mining area.

Abstract

Ultisol dry land is characterized by significantly low organic carbon content, an important factor influencing soil water content and physico-chemical dynamics. The addition of N fertilizer dissolved in seaweed liquid extract as an enrichment solution can change the character of biochar. Therefore, this study aimed to analyze the characteristics of cogongrass biochar enriched with dissolved N fertilizer in seaweed extract of different species and assess its impact on soil water content in Ultisol. Urea was used as a nitrogen source, and biochar enriched with N fertilizer dissolved in seaweed liquid extract from Kappapychus alvarezii, Sargassum sp., and Ulva lactuca was tested. Biochar dose used was 20% of soil weight with a 10% extract concentration for each type. Furthermore, five-level treatments were tested in a pot experiment, namely (i) without biochar, (ii) biochar unenriched, (iii) enriched with N fertilizer dissolved in K. alvarezii extract, (iv) enriched with N fertilizer dissolved in Sargassum sp. extract, and (v) biochar enriched with N fertilizer dissolved in U. lactuca extract. Each treatment was repeated three times, following a randomized block design. The results showed that cogongrass biochar enriched with N fertilizer dissolved in seaweed extract had a more amorphous surface morphology structure. The proportion of elements and functional groups in cogongrass biochar changed. Enriched biochar increased Ultisol moisture levels, but water holding capacity and retention were lower than the unenriched sample.

Abstract

The quality of acidic soil is determined by organic C content produced from rice straw biochar in agriculture. In this context, liquid extract from Kappapychus alvarezii (K-sap) is used as a biochar enrichment agent. Therefore, this research aimed to (i) analyze the character of K-sap enriched rice straw biochar with different volumes, as well as (ii) evaluate the impact on soil water holding capacity, size class distribution, aggregate stability index, respiration rate, and acidic soil chemical characters. The treatment tested was the volume of K-sap kg-1 biochar, namely (i) without biochar, (ii) 0 mL, (iii) 500 mL, (iv) 1,000 mL, and (v) 1,500 mL. Each treatment was repeated three times and placed according to a randomized block design procedure. The area covered by K-sap, pore size, and amorphous degree increased while the pore volume of the biochar surface decreased. The addition of 1,000 mL of K-sap kg-1 biochar released a new peak number associated with the aliphatic and aromatic groups. The K-sap enriched biochar increased the proportion of soil aggregate size of 1-2 mm, water holding capacity, carbon storage, pH, total N, available P and K, exchangeable base cations as well as base saturation. Meanwhile, the concentration of Al3+ and H+ were decreased in the acidic soil solution. The results showed that the performance of rice straw biochar, K-sap volumes, soil chemical quality, water holding capacity, and ability to store carbon of the acidic soil was improved by adding K-sap volume.

Abstract

Pollinator insects play an important role in pollination to increase the productivity of flowering plants. The aim of this study was to analyze the abundance, diversity, and specific taxon of insect pollinators among different vegetable crops in local farmers' gardens. Insects were sampled from four gardens, namely polyculture long bean (KKP), eggplant polyculture (KT), curly chili monoculture (KCK), and Indofood chili monoculture (KCI) used nets and light traps. The results showed that the abundance and diversity of pollinator insects varied between gardens. The pollinator insect community in KCI was most similar to that in KCK; KT was similar to the KCI and KCK groups, while KKP were separate from the KT, KCK and KCI groups. The richest genus occurs in KKP, while chili plantations are the poorest. The apis genus in KKP and KT, and the Nomina genus in KCK and KCI were dominant. The specific pollinator insect genus in KKP is the richest. It concluded that plant species and cropping patterns contribute to the composition and diversity of the pollinator insect community.

Abstract

Taxa diversity within soil fauna functional groups can affected ecosystem functioning such as ecosystem engineers,which influence decomposition and nutrient cycling. The objective of this study is to describe ecological diversityvariation within soil fauna as ecosystem engineers in soil ecosystem of cocoa (Theobroma cacao L.) plantation.Sampling was conducted during one year period from five different ages of plantation. Soil fauna removed from soilcore using hand sorting methods. A total of 39 genera of soil fauna as ecosystem engineers were found during thesestudies. Thirty five genera belong to the group of Formicidae (ants), three genera of Isoptera (termites), and onegenera of Oligochaeta (earthworms). Ecological diversity variation within ecosystem engineers was detected withSimpson indices for dominance and evenness. The highest diversity of ecosystem engineers was in the young ageof plantation. This study reinforces the importance biotic interaction which contributed to the distribution andabundance within soil fauna community as ecosystem engineers in small-holder cocoa plantation.[How to Cite: Kilowasid LMH, TS Syamsudin, FX Susilo and E Sulistyawati. 2012.

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

Earthworms as ecosystem engineers can modify the quality of vermibed assembled from mixed soil with organic material in a vermireactor. Various in shapes of the vermireactor are used to produce a vermicast for biofertilizer in agriculture. The objective of this research was to study the vermicast production and its quality produced from a variety of vermireactor shapes. Earthworm (Pheretima sp.) which was applied to the vermireactor consists of: with- and without of earthworms. Three shapes of the vermireactor, namely cylinder, square, and rectangular has been tested. Compost of Chromolaena odorata pruning mixed with soil was used as vermibed. The vermicast process ran until 28 days. The results showed that vermireactor with earthworms which were successfully converted to vermicast was about 49.24% from the vermibed volume, however, no vermicast formed was found from vermireactor without earthworms. The difference in vermicast produced from different vermireactor shapes was not significant. The value of pH, total-N, and C/N ratio among the vermicast was different. The number of the morphological character of bacteria colonies in the vermicast produced from the square vermireactor was the highest, while from cylinder vermireactor was the lowest. We concluded that the quality of vermicast from earthworm (Pheretima sp.) activity was determined by the shape of the vermireactor.

Abstract

Energy pathways in soil nematode communities consist of energy pathways for roots, bacteria, and fungi. The dominance of the root energy pathway indicated an increase in nematode attacks on the roots that can be regulated through changes in food availability and the environment. This study aimed to (i) determines the effect of the biochar rate on soil nematode energy pathways on local tomato plants and (2) determine the biochar rate that can suppress the dominance of root-feeding nematodes of local varieties of Muna tomato plants. The treatment tested was the biochar rate expressed as a percentage of the biochar weight the soil weight, namely 0%, 5%, 10%, and 15%. Each was repeated three times, randomly placed in the experimental plot following the randomized block design procedure. The results showed that the addition of biochar to 10% of the soil weight decreased the abundance of the total nematodes and family Longidoridae, on the other hand, increased Aphelenchoididae, Spearman rho correlation. The abundance of root eaters decreased; on the other hand, fungivores increased with the biochar rate. Spearman rho indicated that fungivores were negatively correlated with root-feeders and omnivores while positively correlated with predators. It was concluded that applying biochar up to a rate of 10% of the soil weight before planting could suppress the abundance of root-feeding nematodes in the vegetative growth phase of Muna local tomatoes variety.

Abstract

Masyarakat Desa Jati Bali  Kabupaten Konawe Selatan, baik yang produktif maupun non produktif dalam bidang pertanian, akan terlibat dalam proyek PKM ini yang akan menerapkan teknologi pemupukan organik (POC) yang ramah lingkungan. Penanaman sayuran setiap tahun dengan pupuk kimia di desa Jati Bali menurunkan unsur hara tanah dan kesehatan masyarakat. Di era modern ini, asupan nutrisi yang sehat dan bergizi sangat dibutuhkan untuk meningkatkan daya tahan tubuh atau imunitas masyarakat setempat. Oleh karena itu, teknologi POC diperlukan untuk meningkatkan kualitas unsur hara tanah, meningkatkan produksi, dan mendapatkan tanaman sayuran organik. Di desa Jati Bali juga banyak limbah pertanian dan kotoran ternak yang tidak diolah dengan baik, sehingga tidak memberikan nilai tambah bagi masyarakat. Oleh karena itu, penggunaan pupuk organik harus dilakukan untuk memperbaiki lingkungan yang tercemar oleh pupuk kimia dan juga dapat meningkatkan pendapatan masyarakat setempat dengan memanfaatkan limbah di sekitar untuk menjadi pupuk organik. Pupuk organikmemiliki harga lebih mahal daripada limbah kotoran ternak yang belum diolah. Oleh karena itu, solusi yang ditawarkan pada kegiatan PKM ini adalah penggunaan teknologi POC agar tidak ketergantungan dengan penggunaan pupuk kimia. Ini akan membuat lahan usahatani lebih produktif. Dalam pengabdian ini, tiga teknologi akan diterapkan: (1) pembuatan pupuk organik cair; (2) pengemasan; dan (3) pemasaran tanaman sayuran melalui media online seperti Watshap dan Facebook. Kegiatan pengabdian ini telah berhasil dilaksanakan. Hasil pengabdian menunjukkan bahwa pupuk organik cair limbah pertanianjuga dapat menjadi alternatif yang ramah lingkungan dan berkelanjutan untuk menggantikan pupuk kimia sinteti
