Abstract

The number and type of microorganisms in the soil indicate soil fertility. The use of fertilizers can affect the growth of microorganisms in the soil. Quantitative tests are conducted to evaluate how fertilizers affect the presence of bacteria, fungi, and algae. The number of bacteria and fungi is calculated using the standard plate count method, while the number of algae is calculated using the most probable number method. The highest number of bacteria found in urea-phosphate-potassium (UPK) applications of zeolite polymers is 50%, which is 3.4 × 106 CFU/mL; the most fungi are found in 25% of applications, which is 2.5 × 104 CFU/mL. In contrast, the highest algae population was in control soils, 2.7 × 104 CFU/mL. However, for treatment, an enormous amount is found in the administration of 50% zeolite polymer UPK as much as 1.4 × 103 CFU/mL, so it can be concluded that the administration of UPK zeolite polymer affects the number of microorganisms on the cornfield. Keywords: soil microorganism, polyacrylate, UPK, zeolite

Abstract

Organic fertilizers contain complete nutrients needed by plants, such as humic acid and fulvic acid, that can promote plant growth and increase the population of beneficial microbes in the soil. Algae can be an organic fertilizer in extract preparations that can increase plant growth and improve soil composition. The calculated number of microbes from the soil on corn land with the application of algae extracts affects the population of soil microbes both by standard plate count (SPC) and most probable number (MPN) methods. The total number of bacteria by SPC in the control soil was 3.1 × 105 CFU/g, while the total fungus was only 1.7 × 104 CFU/g upon applying 5% algae extract. The most microalgae by MPN in the control ground was estimated to be 2.6 × 104 cells/g. Therefore, the application of algae extract affects the number of soil microbes on corn land compared to control soil. The algae extract reduces the number of bacteria and algae but increases the number of fungi on cornfields. Keywords: algae extracts, cornfields, soil microbes

Abstract

The potential of methane and nitrous oxide productions and community structure of methanogenic archaeahas been characterized by incubation studies and PCR-DGGE approaches, respectively. The results showed thataddition of straw into the soil was the most important factor that influenced CH4 production in this incubation 4 experiment, while N2O production was observed higher in soil without straw amendment under saturated 2 condition. Most of the clone sequences revealed from DGGE band was associated with a archaea lineage,Methanocellales ord. nov (Rice Cluster I). Other sequences belong to Methanomicrobiales, Methanosaetalesand Rice Cluster 2 (RC-2). The study also showed that the hydrogenotrophic methanogens were the dominant members in methanogenic archaea community obtained from tropical paddy field soil, while acetoclastic methanogens present in relatively minor quantity in the soil.

Abstract. Slaughterhouses (RPH) produce large amounts of solid waste every day and have not been utilized optimally. RPH solid waste has great potential to be used as plant fertilizer through the composting process. Composting is expected to change the organic material composition of the abattoir solid waste to be more ideal to support plant growth. This study aims to determine the chemical composition of compost made from waste at RPH Tamangapa Makassar City before and after the composting process. Composting from solid waste at Tamangapa RPH Makassar was carried out using the main ingredients, namely rumen contents (treatment I) and rumen contents mixed with livestock manure in a ratio of 1:1 (Treatment II). The composting process was carried out in a compost box with a size of 40x40x60 cm with a passive aeration system for 4 weeks with three replications. Quantitative data tested in this study included the content of N-total (%), C-Organic (%), P-total (%), K-total (%), C/N ratio, organic matter (%), water content (%) and compost reduction (%). The results showed that the content of elements C, N, P, K, C/N ratio, organic matter, and water content before composting in both treatment I and treatment II were generally still low and almost the same as the raw materials. After the composting process took place, the content of C, P, K, C/N ratios generally showed an increase, while the N content was relatively constant. The results of the analysis showed that there was no significant difference between the chemical composition of the compost in the treatment and both before and after the composting process.Keywords: RPH solid waste, composting process, chemical composition of compost, C/N ratio.

Abstrak. Makanan yang bergizi seimbang dapat diperoleh dari sumber makanan yang mengandung karbohidrat, protein, lemak, vitamin dan mineral. Salah satu pola hidup sehat yang baik diterapkan dengan rajin mengonsumsi sayuran. Salah satu desa yang menjadi mitra dalam Pengabdian Pada Masyarakat (PKM) ini adalah desa Sokkolia yang terletak di Kabupaten Gowa. Desa ini memiliki banyak pohon kelor yang tersebar dibeberapa tempat, namun, karena akses informsasi yang kurang menyebabkan tanaman kelor hanya dimanfaatkan sebagai tanaman pagar dan diolah menjadi sayuran yang kurang memiliki daya tarik dan tidak memiliki nilai ekonomis serta variatif. Tujuan dari kegiatan PKM ini adalah untuk meningkatkan pengetahuan masyarakat tentang diversifikasi olahan daun kelor menjadi olahan yang menarik, bergizi dan bernilai ekonomis. Pelatihan pembuatan diversifikasi daun kelor menggunakan teknologi sederhana. Pada pelaksanaan kegiatan pemberdayaan masyarakat diperoleh hasil: (1) Meningkatkan pengetahuan dan keterampilan masyarakat Desa Sokkolia, Kecematan Bontomaranu, Kabupaten Gowa tentang diversifikasi olahan daun kelor yang bergizi dan bernilai ekonomi dalam meningkatkan potensi masyarakat Desa Sokkolia berskala mikro, (2) Penilaian dalam pelaksanaan kegiatan Program Kemitraan Masyarakat ini diperoleh rerata skor keseluruhan 4,26 (dengan kriteria baik).  Kata kunci: Kemitraan Masyarakat, Pemberdayaan, Diversifikasi, Daun Kelor,Pelatihan

Abstract

Penelitian ini merupakan penelitian deskriptif yang bertujuan untuk menyeleksi (screening) bakteri penambat nitrogen non simbiotik yang diisolasi dari rhizosfer tanaman jagung (Zea mays L.) dan padi (Oryza sativa L.) yang memiliki kemampuan mengekskresikan amonium. Sampel diambil dari daerah Mangkoso, Kabupaten Barru, Provensi Sulawesi Selatan pada daerah rhizosfer tanaman. Isolasi bakteri penambat nitrogen dilakukan dengan menggunakan medium pertumbuhan bebas nitrogen yaitu medium Burk’s dan Ashby. Koloni bakteri yang tumbuh pada medium pertumbuhan selanjutnya dimurnikan dan diuji kemampuan ekskresi amoniumnya dengan menggunakan metode spectrophotometry. Isolat bakteri yang memiliki kemampuan mengekskresikan amonium dikarakterisasi secara morfologi dan fisiologis. Hasil penelitian menunjukkan terdapat 20 isolat bakteri yang mampu tumbuh pada medium bebas nitrogen, namun setelah dilakukan uji ekskresi amonium hanya diperoleh 9 isolat yang memiliki kemampuan mengekskresikan amonium dari masing-masing medium pertumbuhan. Isolat bakteri dan konsentrasi amonium yang diekskresikan masing-masing adalah ABJ211 (179 µg/L), ABP213 (269 µg/L), ABP211 (162 µg/L), ABP131 (254 µg/L), ABP242 (104 µg/L), BBJ221 (263 µg/L), BBJ222 (272 µg/L), BBP222 (269 µg/L) dan BBP214 (257 µg/L). Kesembilan isolat tersebut memiliki karakteristik morfologi dan fisiologis yang bervariasi terutama pada sifat struktur dinding sel (gram), kemampuan hidrolisis pati, gelatin dan kasein, sementara kemampuan dalam mereduksi nitrat dan H2O2 (reaksi katalase positif) serta fermentasi glukosa menunjukkan karakter yang seragam.Kata kunci: Bakteri Penambat Nitrogen, Non Simbiotik, Ekskresi Amonium, Karakterisasi Morfologi dan Fisiologis
