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

Abstrak. Ditinjau dari segi luasan, lahan kering di Indonesia merupakan lahan yang cukup potensial, untuk dikembangkan sebagai areal pertanian. Namun usaha pertanian di areal ini dihadapkan pada beberapa kendala, diantaranya karena lahan ini banyak tersebar di daerah pegunungan dengan topografi yang curam sehingga rawan erosi. Untuk itu usahatani konservasi mutlak perlu dilakukan. Teknik konservasi mekanik berupa teras bangku, yang telah banyak dikenal dan diadopsi petani, diyakini dapat menurunkan erosi, namun teknik ini tidak selalu cocok diimplementasikan pada semua kondisi, selain memerlukan biaya yang cukup tinggi. Oleh karena itu, teknik konservasi vegetatif lebih disarankan untuk diapliksikan di areal ini. Sistem pertanaman lorong (alley cropping) merupakan teknik konservasi vegetatif yang telah terbukti efektif mengendalikan erosi dan aliran permukaan (runoff), kehilangan hara, meningkatkan produktivitas tanah dan tanaman, efisien dari segi biaya, serta dapat diadopsi oleh petani berdasarkan hasil-hasil penelitian. Dengan demikian, sistem pertanaman lorong berpeluang untuk dikembangkan di areal lahan kering dengan memperhatikan keunggulan dan kelemahannya. Makalah ini mengemukakan tentang keunggulan dan kelemahan sistem pertanaman lorong serta peluang dan tantangan yang akan dihadapi di dalam implementasinya di lahan kering berdasarkan hasil analisis SWOT (strengths, weeknesses, opportunities, threats). Pengembangan strategi untuk implementasi sistem alley cropping meliputi strategi yang bersifat teknis dan non teknis.Abstract. In terms of area, upland in Indonesia is a potential land to be developed as an agricultural area. However, this agricultural bussines on this area is faced with several problem, some of them is because the agricultural land is spread in mountainouns area with a steep topography that is easy to erosion, therefore conservation agriculture system is absolutely needed. Mechanical soil conservation techniques such as bench terrace which have been widely known and farmer-friendly are believed to reduce erosion, but this technique is not always suitable to be implemented in all condition other than requiring high cost, therefore vegetative conservation vegetative conservation techniques are more suggested to control erosion in this area. Alley cropping system is a vegetative conservation technique that has been proven effective in controlling erosion and runoff, nutrient loss, increasing land and crop productivity, cost efficient and can be adopted by farmers based on the research results. Thus, the alley cropping system is likely to be developed in upland area with attention to its advantages and disadvantages. This paper presents the advantages and disadvantages of alley cropping system and the opportunities and challenges that will be faced in its implementation in upland based on SWOT (strengths, weeknesses, opportunities, threats) analysis. Development of strategy for implementation of alley cropping system includes technical and non technical strategy.

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.
