Abstract

This study aims to determine the effect of applying chicken manure and volcanic ash on the growth and production of shallots (Allium ascalonicum L.) and P availability in paddy fields. This research was conducted in paddy field at Jln. Harmonika Baru Pasar II, Tanjung Sari Urban Village, Medan Selayang Sub-district, Medan with an altitude of ± 30 meters above sea level. This research was conducted from December 2019 to February 2020. This study used a Randomized Group Design (RAK) with 2 treatment factors. The first factor, chicken manure with 4 levels, namely: A0 = Control (without chicken manure), A1 = 3.75 kg/plot (10 tons/ha), A2 = 7.5 kg/plot (20 tons/ha) and A3 = 11.25 kg/plot (30 tons/ha). The second factor is volcanic ash with 4 levels, namely: V0 = Control (no volcanic ash), V1 = 1.88 kg/plot (5 tons/ha), V2 = 3.75 kg/plot (10 tons/ha) and V3 = 5.62 kg/plot (15 tons/ha). The results showed that the treatment of chicken manure doses up to a dose of 7.5 kg/plot significantly increased leaf length, number of bulbs, wet weight of bulbs/plant, wet weight of bulbs/plot, dry weight of bulbs/plant, dry weight of bulbs/plot, base saturation, C-Organic, soil pH, and soil P availability, but had no significant effect on soil CEC. The treatment of vulaknik ash dose had no significant effect on leaf length, number of tubers, wet weight of tubers/plant, wet weight of tubers/plot, dry weight of tubers/plant, dry weight of tubers/plot, soil CEC, base saturation, C-Organic, soil pH and P availability. The interaction between doses of chicken manure and volcanic ash had a significant effect on the wet weight of tubers/plot and dry weight of tubers/plot, but had no significant effect on leaf length, number of tubers, wet weight of tubers/plant, dry weight of tubers/plant, soil CEC, base saturation, C-Organic, soil pH and P availability.

Abstract

This study aimed to determine the habitat approach on potato cultivation to increase diversity of insects. Habitat improvement design by agricultural system and planting system on different season. This study consisted of two experiments. The first done at planting season from March to July (dry season) and the second done at planting season from October to January (rainy season). Research designed by Split plot design with main plot are farming systems (inorganic farming and organic farming) and the subplot are the design of cropping system (sole potato; potato and cabbage; potato and mustard; potato and onion). The data was analyzed by ANOVA and Tukey test. The result showed that planting season from March to July (dry season) as well as the planting season from October to January (rainy season) showed that insect diversity index, predator population and parasitoid population were higher in organic farming compared to inorganic farming systems. The design of cropping system significantly affect insect diversity index,natural enemies population such as predator Coccinelids and parasitoid Braconid wasp and M. persicae population. In organic farming, intercropping potato with cabbage found the highest insect diversity index and the highest population of parasitoid Braconid wasp and the lowest population of M. persicae. The highest population of predator Coccinelids found at interropping potato with mustard. Combined analysis of the planting on dry season and rainy season showed that insect diversity index and population of parasitoid Baraconid wasp not significantly difference between planting on dry planting and planting on rainy season. On the other hand, population of predator Coccinellids and M. persicae significantly more higher at planting on dry season than planting on rainy season.

Abstract

Desa Paluh Subur berada di pesisir Belawan Kecamatan Hamparan Perak, Kabupaten Deli Serdang Sumatra Utara. Secara umum kondisi penduduk di desa ini memprihatinkan dengan mata pencaharian bercocok tanam padi dengan pengairan tadah hujan satu kali dalam setahun. Produktivitasnya masih jauh dari rata-rata produktifitas nasional. Penghasilan tambahan diperoleh dari ternak dan tanaman hortikultura. Teknologi budidaya padi sawah yang dikembangkan masyarakat selama ini masih sangat sederhana dan belum memanfaatkan potensi lahan secara maksimal. Tujuan Pengabdian Masyarakat bertujuan untuk menerapkan sistem pertanian terpadu untuk memaksimalkan potensi wilayah. Metode pelaksanaan adalah Participatory approach melalui penyuluhan, diskusi, praktek langsung dan pembuatan demonstrasi plot teknologi budidaya padi sawah dengan Metode SRI yang terintegrasi dengan peternakan dan memanfaatkan potensi lingkungan sekitar sehingga produksi padi dan pendapatan petani meningkat. Hasil kegiatan demonstrasi pada plot percobaan menunjukkan ada peningkatan produksi padi sebesar 47 %, mengurangi kebutuhan bibit sebesar 88 % dan mengurangi penggunaan pupuk Anorganik sebesar 35 % sebagai akibat pemanfaatan Jerami padi sebagai pupuk organik Bokashi. Hasil kegiatan penyuluhan menunjukkan bahwa ada peningkatan pengetahuan petani dalam hal pemanfaatan jerami padi sebagai bahan organik penambah unsur hara tanaman, pemanfaatan tumbuhan sekitar sebagai bahan untuk pestisida nabati, pengenalan kebutuhan unsur hara tanaman berdasarkan warna daun dan efisiensi penggunaan air dan bibit melalui polatanam padi dengan Metode SRI.  Hasil Integrasi usaha dengan peternakan kambing belum menunjukkan hasil yang signifikan sampai kegiatan pengabdian Masyarakat ini berakhir

Abstract

Salah satu metode pemulihan kualitas tanah tercemar logam berat adalah menggunakan teknik remediasi, yaitu kegiatan untuk membersihkan permukaan tanah yang tercemar. Penelitian ini menggunakan tanaman sawi yang ditanam pada media tanah tercemar logam berat Pb dan Cu, diinokulasi dengan konsorsium bakteri (corynebacterium glutamicum, lactobacillus sp.) dan arang sekam. Hasil penelitian menunjukkan konsentrasi logam berat Pb dan Cu, baik pada tanah maupun tanaman, nyata mengalami penurunan dengan semakin bertambahnya taraf inokulasi bakteri dan arang sekam. Rerata besar penurunan Pb pada tanah dan tanaman dengan perlakuan bakteri : 1,28% dan 0,29%; dan rerata penurunan kandungan Cu pada tanah dan tanaman : 1,03% dan 0,17%. Sedangkan rerata besar penurunan Pb pada tanah dan tanaman dengan perlakuan arang sekam masing-masing sebesar 0,44% dan 0,07%; dan rerata penurunan kandungan Cu pada tanah dan tanaman 0,34% dan 0,08%. perlakuan inokulasi bakteri pada taraf 5 g tanaman-1 dan arang sekam 20 g tanaman-1 mengakibatkan jumlah daun terbanyak. Tinggi tanaman sampai 4 minggu setelah tanam nyata mengalami peningkatan, sedangkan jumlah daun dan bobot basah nyata mengalami peningkatan sampai 5 minggu setelah tanam dengan pemberian arang sekam. Tanaman sawi dengan inokulasi bakteri dan pemberian arang sekam disamping dapat meningkatkan kesuburan tanah dengan memperbaiki sifat-sifat tanah, juga dapat berkontribusi terhadap stabilisasi logam berat pada tanah. Kata kunci : remediasi, logam berat Pb dan Cu, konsorsium bakteri,arang sekam
