“…Salah satu metode pembelajaran yang dapat digunakan untuk memecahkan masalah tersebut adalah dengan menginovasi dan merancang strategi pelaksanaan pembelajaran dengan kombinasi metode pembelajaran berbasis masalah atau Problem Based Learning (PBL) dengan pendekatan Pendidikan kecakapan hidup (Life Skills) dapat digunakan oleh guru bidang studi ekonomi (kewirausahaan), Biologi dan pemasaran berbasis Teknologi Informasi. Kombinasi metode PBL dengan pendekatan Pendidikan Life Skills merupakan salah satu metode pembelajaran telah banyak diaplikasikan dan sesuai dalam upaya menanamkan jiwa dan mengembangkan program kewirausahaan dengan mengintroduksi pengetahuan dan keterampilan serta penguasaan teknologi sesuai kebutuhan siswa seperti mengembangkan usaha tani-ternak terinegrasi (Ismail et al, 2018;Furtak et al, 2019;Maramis et al, 2019). Program pendidikan Life Skills berwirausaha tani-ternak terintegrasi tersebut sangat beralasan karena selain didukung oleh ketersediaan lahan milik sekolah yang cukup luas (Gambar 2), juga menjadi media pembelajaran pendidikan Life Skills berwirausaha tani-ternak terintegrasi sekaligus memenuhi kebutuhan konsumsi pangan bagi masyarakat (Gambar 3).…”

Salah satu penyumbang tingginya angka pengangguran terbuka adalah terus meningkatnya angka lulusan Sekolah Menengah Atas (SMA) tidak melanjutkan studi ke Perguruan Tinggi (PT). Sekolah Menengah Atas (SMA) Negeri 1 Kabaruan Talaud merupakan salah satu penyumbang tingginya angka pengangguran terbuka lulusan yang tidak melanjutkan studi ke PT dan tidak bekerja. Oleh karena itu sangat diperlukan pembekalan lulusan dengan kompetensi tambahan agar dapat menciptakan lapangan kerja sendiri antara lain dengan menanamkan jiwa kewirausahaan kepada siswa sebelum menamatkan pendidikan di SMA melalui Program Kemitraan Masyarakat (PKM). Kegiatan PKM ini ini bertujuan untuk menanamkan jiwa kewirausahaan di SMA Negeri 1 Kabaruan. Metode yang digunakan adalah kombinasi metode Pembelajaran Berbasis Masalah atau Problem Based Learning (PBL) dengan pendekatan Pendidikan Kecakapan Hidup (Life Skill) berwirausaha tani-ternak terintegrasi dengan mengintroduksi budidaya tanaman pangan (sayuran, kacang tanah, dan jagung serta ternak ayam). Hasil kegiatan PKM ini adalah sebagai berikut; (1) terfasilitasi upaya peningkatan pengetahuan dan keterampilan berwirausaha tani ternak terinegrasi pada siswa SMA Negeri 1 Kabaruan Talaud, (2) terfasilitasi satu kegiatan Pendidikan Life Skill wirausaha tani-ternak terintegrasi sebagai media pembelajaran biologi dan berwirausaha, (3) Adanya peningkatan pengetahuan dan keterampilan pada siswa dalam berwirausaha tani-ternak terintegrasi (4) Dihasilkan Rancangan Pembelajaran Biologi dan Kewirausahaan dengan metode Problem Based Learning dan pendekatan pendidikan Life Skills.

“…Microorganisms consists of one of the essential elements in regulating biochemical reactions and cycling in soil (Gałązka et al 2016). Not only they are responsible for the degradation of organic remnants, but also humus formation, circulation of biogenic components along with their transformation into forms which are available for plants and also, degradation of pollutants (Furtak and Galazka, 2019). The kinetics of the microbial activities is very important to understand under this condition as the very presence of these microbes decides the several other processes such as methane formation, ammonization, nitrogen fixation, nitrification etc.…”

Microorganisms play crucial role in the ecosystem building. Their presence or absence in a particular environment are indicative of the web of interactions they undergo to impact the life of other components of the system. The current experiment was undertaken in rice-rice cropping sequence to understand the changes in composition of microorganism as a result of interaction of herbicide and different nutrient sources added to soil under lowland area. The experiment was divided into two simultaneous studies, i.e. field experiment and metagenomic study, to obtain the rice yield and soil microbial dynamics, respectively. Pooled soil samples were collected from rice field with constant herbicide application, i.e. Pyraszosulfuron (pre-emergent) @25g/ha + 2, 4-D (post-emergent @0.5 kg/ha), but with 5 different sources of nutrients, viz, T0- absolute control, T1- 100% N-P2O5-K2O through inorganic fertilizers (recommended dose of 40-20-20 kg/ha)), T2- 75% N through inorganic + 25% N through FYM (P2O5 & K2O recommended doses), T3- 75% N through inorganic + 25% N through vermicompost (P2O5 & K2O recommended doses) and T4- 75% N through inorganic + 25% N through crop residues and bio-fertilizer (P2O5 & K2O recommended doses). Based on the amplicon DNA sequencing approach, it was observed that though there was overall increase in bacterial phyla, viz., Chloroflexi, Actinomycetes, Euryarchaeota, Firmicutes in all the treatments from 0 days after transplanting (DAT) to physiological maturity of plant, where, soil treated with vermicompost (TH3) showed a dramatic increase in the population of Firmicutes. Amongst fungal populations, Actinomycetes increased in all the soils from 0 DAS to physiological maturity, the increase was lowest in soil treated with vermicompost while it was highest in soil having crop residues (T4). The results were concomitant to the biological yield of rice that was observed highest in the soil treated with vermicompost along with inorganic fertilizers. The results could be attributed to the favourable niche provided by vermicompost that resulted in synthesis and release of plant hormones, metabolites and antibiotics by the bacterial population leading to dominance of the bacteria as compared to the other treatments.

The effects of integrated nutrient-management (INM) practices on soil quality are essential for sustaining agro-ecosystem productivity. The soil quality index (SQI) serves as a tool to assess the physical, chemical, and biological potential of soils as influenced by various edaphic and agronomic practices. A multiyear (2018–2021) field experiment was performed at the University Organic Research Farm, Narendrapur, West Bengal, India, to investigate the influence of integrated and sole applications of different conventional fertilizers, organic (e.g., vermicompost), and natural farming inputs (e.g., Dhrava Jeevamrit and Ghana Jeevamrit) on SQIs and crop productivity of rice–mustard–green gram-based cropping systems. A total of 12 parameters were selected for the assessment of SQI, amongst which only four, namely pH, organic carbon %, total actinomycetes, and bulk density, were retained for the minimum data set based on principal component analysis (PCA). In this study, the maximum SQI value (0.901) of the experimental soil was recorded in the INM practice of 25% organic and 25% inorganic nutrient inputs, and the rest with natural farming inputs, which augments the SQI by 24% compared to the 100% inorganic nutrient treatment. Amongst the different soil parameters, the highest contribution was from the pH (35.18%), followed by organic carbon % (26.77%), total actinomycetes (10.95%), and bulk density (6.98%). The yields in different cropping systems varied year-wise across treatments. Notably, the highest yield in rainy rice was estimated in the 100% organic treatment, followed by INM practices in the subsequent years, and finally, the combination of organic and natural inputs in the final year. In the case of mustard, the combination of organic and natural inputs resulted in the highest productivity in the initial and last years of study, while the 100% organic treatment resulted in higher productivity in subsequent years. Green gram showed a dynamic shift in yield between the 100% organic and integrated treatments over the years. Further, a strong correlation was also established between the soil physico-chemical parameters and the SQI. Overall, this study concludes that the natural and organic input-based INM practice enhances the soil quality and crop productivity of the rice–mustard–green gram cropping system under the coastal saline zone.
