Abstract

Cekaman air merupakan salah satu faktor pembatas pertumbuhan dan produksi tanaman termasuk cabai (Capsicum annuum L.). Produktivitas tanaman merupakan karakter yang kompleks sehingga hubungan antarkarakter perlu diketahui untuk mendapatkan kriteria seleksi yang tepat untuk perbaikan tanaman. Penelitian ini bertujuan mengetahui kriteria seleksi terhadap produksi tanaman cabai toleran kekeringan pada fase pembungaan. Penelitian disusun menggunakan Rancangan Acak Lengkap dengan tiga taraf cekaman air, yaitu 100% kapasitas lapang (kontrol), 50% kapasitas lapang (medium stress), dan 25% kapasitas lapang (extreme stress). Hasil analisis korelasi menunjukkan bahwa berbagai karakter yang diamati memperlihatkan perbedaan asosiasi dengan level cekaman kekeringan. Karakter panjang akar tidak dapat digunakan sebagai kriteria seleksi tanaman cabai yang toleran terhadap kekeringan karena panjang akar tidak berkorelasi secara signifikan dengan bobot buah per tanaman pada 50% dan 25% kapasitas lapang. Berdasarkan korelasi dan analisis lintas pada kondisi normal (100% kapasitas lapang) dan kondisi tercekam (50% kapasitas lapang), karakter jumlah buah dan persentase fruit set berkorelasi positif dan berpengaruh langsung terhadap bobot buah per tanaman sehingga dapat digunakan sebagai kriteria seleksi untuk perbaikan tanaman cabai yang toleran kekeringan.KeywordsCekaman air; Cekaman kekeringan; Kriteria seleksi; Cabai; Capsicum annuum LAbstractWater stress is one of limiting factors for plant growth and production, including chili (Capsicum annuum L.). Plant productivity is a complex character so the relationship between characters needs to be known to get the right selection criteria for crop improvement. This study aimed to determine the selection criteria for the production of drought-tolerant chili pepper at the flowering phase. The research arranged under completely randomized design with three levels of water stress, namely 100% water field capacity (control), 50% water field capacity (medium stress) and 25% water field capacity (extreme stress). The results of the correlation analysis showed that the various characters observed exhibited differences associations with drought stress levels. Root length cannot be used for selection criterium of drought tolerant on chili because it was no positive significantly correlated to fruit weight per plant at 50% and 25% water field capacity. Based on correlation and path analysis in normal and drought conditions, the number of fruits and percentage of fruit set can be used as selection criteria for genetic improvement of drought-tolerant on chili plants because these characters were significantly positively correlated and had a direct effect on fruit weight of the plant.

[Morpho-physiologcal Characters of Okra Leaf (Abelmoschus esculentus L.) on Various Different Application of Fertilizers through Minus One Test]Buah okra dikenal sebagai bahan pangan fungsional karena mengandung serat pangan tak larut dan larut, serta mengandung metabolit sekunder berupa senyawa fenolik dan  flavonoid yang bersifat antioksidan. Salah satu faktor penentu dalam budidaya tanaman okra adalah pemupukan. Penelitian ini bertujuan mendapatkan informasi tentang pengaruh pemupukan dengan metode minus one test terhadap karakter morfofisiologi daun okra. Percobaan dilaksanakan di tanah latosol di Kebun Percobaan IPB Leuwikopo, Dramaga, Bogor (250 m dpl.) pada bulan Juli – Oktober 2018. Rancangan percobaan yang digunakan dalam percobaan  ini ialah Rancangan Kelompok Lengkap Teracak (RKLT) dengan satu faktor tiga kali ulangan. Perlakuan pemupukan terdiri atas tanpa pemupukan, NPK + pupuk kandang, NPK, NP (-K), NK (-P), dan PK (-N). Hasil percobaan menunjukkan bahwa nilai peubah morfologi yang diamati tidak berbeda nyata antarperlakuan. Peubah fisiologi yang berbeda nyata ditemukan pada hara Mg. Secara umum belum dapat ditentukan satu unsur hara terpenting yang terbukti dapat menjadi pembatas bagi morfofisiologi daun okra. Nilai rerata karakteristik daun dan laju pertumbuhan pada tanaman okra yang mendapat perlakuan tanpa pemupukan dan kurang N lebih rendah dibandingkan dengan perlakuan lainnya. KeywordsOkra (Abelmoschus esculentus L); Morfologi daun; PupukAbstractOkra fruit is known as a functional food mainly because it contains insoluble and soluble food fiber, and have secondary metabolites such as phenolics, and flavonoids that have antioxidant effects. Fertilization is one of the determining factors in for plant growth, but the limiting nutrient involving plant growth and production has not well known yet. This study was conducted using minus one test on NPK fertilization. The objectives of this research are to obtain information about the effect of fertilization with the minus one test method on the morphophysiological character of okra leaves. The experiment was carried out in latosol soil in the IPB Leuwikopo Experiment Garden, Dramaga, Bogor (250 m asl, ) in July – October 2018. The experimental design used in this experiment was the Randomized Complete Group Design (RCBD) with one factor and three replications. Fertilization treatment consisted of no fertilization, NPK + manure, NPK, NP (-K), NK (-P), and PK (-N). The results showed, that morphological values were not significantly different between treatments. Significantly different among the physiological variables were found in the results of Mg nutrient analysis. Generally, that one important nutrients that could be a limitation for the growth of okra plants could not be determined. There were indication, that based on the average value of leaf characteristics and growth rate, okra plants that were treated without fertilization and minus N tended to be lower compared to other treatments.

Abstract

Indonesia selama ini mengimpor sebanyak 95% bawang putih konsumsi, namun direncanakan bahwa Indonesia harus dapat berswasembada bawang putih pada tahun 2021. Untuk itu dilaksanakan upaya perluasan tanam mulai dari penggunaan dana APBN, penanaman oleh importir, maupun penanaman secara swadaya petani yang akan membutuhkan benih bawang putih dalam jumlah banyak. Dengan alasan terbatasnya jumlah benih bawang putih dan meningkatnya permintaan untuk penanaman maka harga benih bawang putih di tingkat petani melonjak naik sehingga perlu dibuat aturan mengenai harga bawang putih agar semua pemangku kepentingan dapat saling mendapatkan keuntungan. Penelitian ini bertujuan merekomendasikan harga bawang putih yang layak sesuai dengan harga pasar dan keuntungan petani. Data yang digunakan berupa data primer input dan output usahatani yang dikumpulkan dari 86 orang petani di tiga sentra produksi bawang putih yang selama ini konsisten menanam bawang putih, yaitu Lombok Timur, Magelang, dan Temanggung. Data sekunder berupa data Upah Minimum Kabupaten (UMK) diperoleh dari BPS untuk membandingkan dengan keuntungan usahatani yang diperoleh. Hasil penelitian menunjukkan bahwa harga jual yang layak untuk bawang putih konsumsi adalah Rp15.000,00/kg dan untuk benih sebesar Rp53.000,00/kg. Apabila harga jual kurang dari harga tersebut maka keuntungan usahatani akan lebih rendah dari UMK sehingga tidak akan menarik untuk petani.KeywordsBawang putih; Biaya usahatani; Harga jual; UMKAbstractIndonesia for long years has been importing as much as 95% of the consumption of garlic, but it is planned that Indonesia should be able to self-sufficient in garlic in 2021. Therefore, efforts are made to expand planting, starting from the use of national budget funds, planting by importers, as well as planting independently farmers who will need seeds garlic in large quantities. Due to the limited amount of garlic seeds and the increasing demand for planting, the price of garlic seeds at the farmer level soared. Regulations should be made regarding the price of garlic so that all stakeholders can benefit from each other. This study aims to recommend the price of decent garlic according to market prices and farmers’ profits. The data used in the form of farm input and output primary data collected from 86 farmers in three centers of garlic production that have consistently planted garlic, namely East Lombok, Magelang, and Temanggung. Secondary data in the form of District Minimum Wage data was obtained from Statistics Indonesia (BPS) to compare with farm profits obtained. The results of the study show that the reasonable selling price for garlic consumption is IDR 15,000/kg and for seeds of IDR 53,000/kg. If the selling price is less than this price, the farming profit will be lower than the District Minimum Wage so that it will not be attractive to farmers.
