Abstract

 This study aimed to determine the response of the growth of sweet corn plants and weed density to the treatment of bio-fertilizer based on arbuscular mycorrhizal fungi and cow manure fertilizer. The study was conducted using a randomized complete block design (RCBD) in a factorial pattern. The first factor was arbuscular mycorrhiza fungi (AMF) consisting of four doses, namely without AMF (A0), AMF 5 g/planting hole (A1), AMF 10 g/planting hole (A2), AMF 15 g/ planting hole (A3). The second factor was cow manure fertilizer con-sisting of three doses, namely without cow manure fertilizer (B0), cow manure fertilizer 3 kg/plot (B1), cow manure fertilizer 6 kg/plot (B2). The treatment applied consisted of 12 combinations of treatments with 3 replications, so there were 36 experimental units. The observed variables were plant height, stem diameter, leaf area and weed density. The results showed that the average height of sweet corn was best at 42 DAP in the treatment of cow manure fertilizer 6 kg/plot (B2) as 111.6 cm. The average highest of stems diameter was at 14 DAP in the treatment of cow manure fertilizer 6 kg/plot (B2) as 0.40 cm. The average leaf area of sweet corn was at the age of 28 DAP was highest in the combination treatments cow manure fertilizer 6 kg/ plot (A0B2) and without AMF as 894.5. The weed species with the highest density found was I.cylindrica as 0.5-32.4%, C. kyllingia as 1.3-41.8%, C. rotundus as 1.3-30.3% and F.miliaceae as 1.2-12.7%.

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

Biochar enriched with fertilizers has the potential to improve the quality of acid soils. In the agricultural sector, it was reported that the sap of Kappapychus alvarezii (K-sap) is often used as a biofertilizer. Therefore, this study aimed to (i) examine the character of biochar enriched with the K-sap and (ii) analyze the soil quality after incubation. This study was carried out using two treatment factors arranged in a randomized block design, namely the biochar dose at 0%, 2.5%, 5.0%, and 7.5% in weight and K-sap at concentrations of 0%, 5%, 10%, and 15%.  Ten kilograms of acid soil were incubated with K-sap enriched biochar for up to 2 weeks in each experimental pot. The results showed that the absorption band increased with the K-sap concentration for the functional group associated with the OH-stretching of the biochar enriched with K-sap was stronger and wider than the unenriched. The peak elevation pattern detected by X-ray diffraction for all biochars was similar. The dosage of 7.5% biochar enriched with 5%-10% K-sap concentrations increased pH, EC, organic C, total N, C:N ratio, available P, and exchangeable K, Ca, Mg, and Si than those without treatment. Furthermore, ammonium and total spores of arbuscular mycorrhizal fungi decreased, flagellates increased with and without the biochar, while the nitrate, total bacteria, and fungi of all treatments were similar. Based on these results, it was concluded that biochar enriched with K-sap could improve the quality of acid soil.

Abstract

This PKMI activity will apply POP technology (organic plus fertilizer) which is environmentally friendly in the community living in Wakadia Village, Muna Regency, both non-productive and productive communities in the agricultural sector. Wakadia village is an agricultural area with land conditions that continue to grow vegetables throughout the year using chemical fertilizers so that this will have an impact on decreasing the condition of soil nutrients and have an impact on the health of the people of Wakadia village. In this New Normal era, healthy and nutritious nutrition is urgently needed to increase the resistance or immunity of the local community, so that to fulfill this nutrition organic vegetables that are free of chemicals are needed. Therefore, POP technology is needed to improve the quality of soil nutrients, increase production and obtain organic vegetable crops. In the village of Wakadia there are also many agricultural wastes and livestock manure that are abundant but have not been optimally processed so that they do not provide added value to the village community, so PKMI activities must be carried out to improve environmental conditions that have been polluted due to the use of chemical fertilizers, and also can increase the income of the local community by utilizing existing waste to be used as organic fertilizer. Where organic fertilizer has a higher price than livestock manure that has not been processed. Thus, the solution offered in this PKMI activity is the application of technology in changing the use of chemical fertilizers with the use of POP technology so that farming land is even more productive. The forms of technology applied to the community in this service are (1) technology for making organic fertilizer plus (2) technology for packaging organic fertilizer plus (3) technology for marketing horticultural crops through online media (Facebook and Watshap).

Abstract

Jagung merupakan tanaman dengan seribu manfaat, seluruh dari bagian tanaman jagung dapat dimanfaatkan. Manfaat pokok tanaman jagung adalah pemanfaatan biji jagung yang diolah sebagai makanan pokok. Selain itu limbah dari tanaman serba guna ini juga dapat dimanfaatkan untuk berbagai produk yang bernilai ekonomis seperti batang, daun dan tongkol jagung. Hal ini menjadikan limbah jagung yang diolah sebagai bahan organik seperti pupuk organic cair sehingga dapat menambah kandungan unsur hara yang diperlukan tanaman. Oleh sebab itu, sangat diperlukan teknologi POC untuk meningkatkan kualitas unsur hara tanah, peningkatan produksi dan mendapatkan tanaman jagung organik. Desa Warambe merupakan daerah pertanian dengan kondisi lahan yang terus dilakukan penanaman jagung sepanjang tahun dengan menggunakan pupuk kimia sehingga ini akan berdampak menurunnya kondisi unsur hara tanah dan berdampak bagi kesehatan masyarakata desa Warambe.  Di desa Warambe selain terdapat limbah-limbah pertanian juga terdapat limbah-limbah rumah tangga yang melimpah tetapi belum diolah secara optimal sehingga tidak memberikan nilai tambah bagi masyarakat desa tersebut, maka tujuan kegiatan PKM ini harus dilakukan untuk memperbaiki kondisi lingkungan yang telah tercemar akibat penggunaan pupuk kimia, dan juga dapat menambah penghasilan masyarakat setempat dengan memanfaatkan limbah yang ada disekitar untuk dijadikan pupuk organik. Dimana pupuk organik memiliki harga yang lebih tinggi dibandingkan limbah kotoran ternak yang belum diolah. Dengan demikian, solusi yang ditawarkan dalam kegiatan PKMI ini adalah penerapan teknologi dalam merubah penggunaan pupuk kimia dengan penggunaan teknologi POC sehingga lahan usahatani lebih produktif lagi. Adapun bentuk teknologi yang diterapkan ke masyarakat dalam pengabdian ini adalah (1) teknologi pembuatan pupuk organik cair (2) teknologi pengemasan pupuk organik cair (3) Teknologi pemasaran tanaman jagung melalui media online (Facebook dan Watshap). Pupuk organik cair yang berasal dari limbah-limbah pertanian, diminati oleh petani untuk digunakan sebagai pupuk dalam meningkatkan pertumbuhan dan produktivitas pada tanaman jagung di Desa Warambe Kecamatan Parigi Kabupaten Muna, dan dapat mendorong petani untuk mengembangkan sistem pertanian yang ramah lingkungan atau sistem pertanian organik. Maka dengan kegiatan PKMI petani sudah memiliki kemampuan dasar dalam sistem budidaya tanaman sehat yang berwawasan lingkungan yang dapat menghasilkan produk-produk pertanian yang dapat diterima oleh masyarakat luas.
