Abstract

Tanah di lahan kering merupakan lahan yang terdegradasi. Oleh karena itu diperlukan perbaikan kualitas tanah tersebut. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan mulsa dan bahan pembenah tanah dalam memperbaiki sifat fisik dan kimi tanah serta kaitannya dalam meningkatkan produksi bawang merah. Penelitian aplikasi mulsa dan pembenah tanah pada pertanaman bawang merah dilaksanakan pada bulan Maret sampai Juni musim tanam (MT) 2016 di Desa Bayongbong, Kecamatan Bayongbong, Kabupaten Garut, Provinsi Jawa Barat. Rancangan percobaan yang digunakan adalah petak terpisah (Split Plot Design) dengan 3 ulangan. Main plot adalah jenis mulsa yaitu: Tanpa mulsa (M-0), Mulsa plastik (M-1), dan Mulsa jerami (M-2) sedangkan sub-plot adalah: 1) Teknologi petani (B-1), 2) B-1+ NPK rekomendasi (B-2), 3) B-1 + 5 t ha-1 Dolomit (B-3), 4) B-1 + 5.0 5 t ha-1 Biochar (B-4), 5) B-1 + 5 5 t ha-1 Dolomit + 5.0 5 t ha-1Biochar (B-5). Hasil penelitian menunjukkan bahwa mulsa dan pembenah tanah memperbaiki sifat fisika tanah (retensi air, porositas dan agregasi tanah). Selain itu memperbaiki sifat kimia tanah (pH, Ca2+, K+, Ca-dd, K-dd, KB). Ada interaksi antara musa dan pembenah tanah terhadap hasil umbi bawang merah. Hasil umbi 18.35 t ha-1 didapatkan pada perlakuan mulsa plastik dengan teknologi petani dtambah 5 t ha-1 dolomit yang meningkatkan hasil sampai 57.8% dibandingkan kontrol, tanpa mulsa dengan teknologi petani. Kata kunci : hasil umbi, sayuran tropis, sifat fisika tanah, sifat kimia tanah

Abstract

Water scarcity is the main factor causing crop production decrease and harvest failure in the upland areas. To improve water use efficiency by plants, Management Allowable Depletion (MAD) concept can be applied. MAD is the degree of soil dryness that still lead to optimum crop yied. This research was aimed to: 1) determine a correct MAD-level in order to achieve the optimum water use efficiency and 2) evaluate the effect of irrigation water sources on water use efficiency. The research was carried out on a Typic Kanhapludults at Tamanbogo Experimental station, East Lampung in dry season of 2005. Chili (Capsicum annum) was use as an indicator crop. The size of experimental plot was 5 x 10 m, that was arranged in split-plot design with 3 replications. The treatments were irrigation water sources designed as main plot which consisted of: A1 = ground water A2 = surface water, while MAD-level was designed as sub-plot, which consisted of : I1 = 20% of available water, I2 = 40% of available water, I3 = 60% of available water, I4 = 80% of available water, and I5 = 100% of available water. Irrigation was provided to reach 80, 60, 40, and 20% available water respectively. For the I5 treatment, irrigation was applied every day. The results showed that MAD-level of 60% of available water (I3) with the average of 9.6 mm of irrigation water, applied every three days, gave themost optimum crop yield and water use, thus achieving the highest water use efficiency. The surface irrigation water had a better quality than ground water,leading to a better plant growth, a higher crop yield and a higher water use efficiency than ground water

Abstract

Penelitian ini bertujuan meningkatkan hasil belajar siswa kelas VIII SMP N 2 Adimulyo tahun pelajaran 2017/2018, dalam materi tentang kondisi fisik wilayah Indonesia. Salah satu upaya untuk mencapainya adalah dengan menggunakan cara baru dalam proses pembelajaran, misalnya dengan pembelajaran menggunakan metode Make A Match. Penelitian ini dilakukan dengan menggunakan metode deskriptif komparatif melalui penelitian tindakan kelas. Data yang dikumpulkan dalam penelitian ini terdiri dari data kuantitatif dan data kualitatif. Data kuantitatif diperoleh dari hasil tes diolah dengan menggunakan deskripsi persentase. Data kualitatif diperoleh dari pengamatan yang dilakukan oleh peneliti. Kedua data tersebut kemudian digunakan untuk mendiskripsikan keberhasilan metode Make A Match dalam meningkatkan hasil belajar siswa. Hasil penelitian menunjukkan bahwa metode Make A Match dapat meningkatkan hasil belajar materi kondisi fisik wilayah Indonesia. Peningkatan tersebut antara lain siswa yang memperoleh nilai batas KKM atau lebih sejumlah 7 siswa (21,8%) meningkat menjadi 12 siswa (37,5%) pada Siklus I dan meningkat lagi menjadi 25 siswa (78,12%) pada Siklus II.

Abstract

Acid upland soil in Indonesia has a great potential for agricultural development but the soil physical properties have been degraded. The use of manure and direct application of Gresik phosphate rock (PR) was an alternative to improve land productivity and crop yields. The objective of the study was to evaluate the effects of manure and P sources on soil physical  properties and yield of foods crop that was arranged on intensive cropping systems of upland rice + maize -/- cassava- mungbean. The experiment was carried out in Tamanbogo Station Farm, East Lampung since 2007 until 2009 using randomized complete block design with 3 replications. The treatments were (1) 10 t ha-1 manures+1 t ha-1 of PR, (2) Without manure+1 t ha-1 of PR, (3) 10 t ha-1 manures+100 kg ha-1 of SP 36, and (4) Without manure+100 kg ha-1 of SP 36. The results showed that the application of manure along with PR improved soil physical characteristics of ultisol soil and gave the highest yield of foods crops with B/C in year 3th was 3.60.

Abstract

Acid upland soil in Indonesia has a potential for agricultural development but it has constraints low of organic C and available P as well as the soil physical properties have been degraded. The use of manure and direct application phosphate rock (PR) was an alternative to improve land productivity and crop yields. The objective of the study was to examine the effects of manure and the sources of P on soil physical and chemical properties and yield of foods crop that was arranged on intensive cropping systems of upland rice + maize -/- cassava- mungbean. The experiment was carried out at Tamanbogo Station Farm, East Lampung since 2007 until 2009 using randomized completely block design with 3 replications. The treatments were (1) 10 Mg ha-1 manures + 1 Mg ha-1 of RP, (2) without manure + 1 Mg ha-1 of PR, (3) 10 Mg ha-1 manures + 100 kg ha-1 SP 36, and (4) without manure + 100 kg ha-1 SP 36. The results showed that the application of manure along with PR improved soil chemical and physical characteristics. Its improvement affected the yield of foods crops, hence the profit increased with B/C ratio between 2.88-3.60.
