Abstract

Produktivitas cabai besar di Provinsi Lampung menurun pada tahun 2018 sebesar 24,7%, dari 88,23 kuintal/ha pada tahun 2017 menurun menjadi 66,41 kuintal/ha pada tahun 2018. Hal tersebut salah satunya disebabkan karena kandungan C-organik tanah yang rendah dan tingginya kerontokan bunga cabai. Limbah baglog jamur merupakan bahan yang potensial digunakan sebagai bahan pembenah tanah karena memiliki sifat porous, sehingga mudah menyerap dan menyimpan air, serta mengalirkan air dalam jumlah yang banyak dan mengandung nutrisi untuk tanaman. Untuk mengurangi serangan kerontokan bunga cabai dapat digunakan sungkup plastik berbentuk melengkung yang dapat menahan jatuhnya air hujan secara langsung pada tanaman dan mengoptimalkan penggunaan pestisida dan pupuk daun.  Penelitian ini dilaksanakan dengan tujuan mengkaji pengaruh pemberian limbah baglog dan sungkup plastik terhadap pertumbuhan dan hasil cabai, dan mengkaji pengaruh interaksi antara pemberian limbah baglog dan sungkup plastik terhadap pertumbuhan dan hasil cabai. Penelitian ini telah dilaksanakan di lahan praktik hortikultura Politeknik Negeri Lampung, Bandar Lampung. Waktu penelitian dimulai bulan Juli sampai Oktober 2020. Penelitian ini merupakan percobaan faktorial 3 x 2 dengan menggunakan Rancangan Acak Kelompok (RAK) dengan tiga ulangan. Faktor pertama yang dicoba yaitu dosis limbah baglog yang terdiri dari 0 (kontrol), 20 ton/ha dan 40 ton/ha. Faktor kedua adalah penggunaan sungkup plastik yang terdiri dari tanpa sungkup (kontrol) dan pemberian sungkup plastik. Data yang diperoleh dianalisis dengan menggunakan uji F, jika nyata dilanjutkan dengan Uji BNJ pada taraf 5%. Hasil penelitian menunjukkan pemberian limbah baglog jamur meningkatkan tinggi tanaman, jumlah cabang dan bobot buah cabai per petak. Dosis limbah baglog 40 ton/ha memberikan hasil terbaik pada jumlah cabang dan bobot buah cabai per petak. Penggunaan sungkup plastik tidak berpengaruh terhadap pertumbuhan dan hasil cabai, dan tidak terjadi interaksi antara pemberian limbah baglog jamur dengan penggunaan sungkup plastik terhadap semua variabel pengamatan.

Abstract

Continuous use of chemical fertilizers can reduce soil fertility and decrease crop quality.  To maintain the soil fertility and increase the crop production, can be done by combining chemical fertilizers with organic fertilizers, so  the use of chemical fertilizers can be reduced by being substituted by organic fertilizers.  Liquid smoke (bamboo vinegar) is one of natural materials which is potential to be liquid organic fertilizer. The research on the potential of bamboo vinegar is mostly directed at its  function as a food preservative and vegetable pesticide,  however, the bamboo vinegar also potential as an organic material that can reduce the use of chemical fertilizers in plant cultivation.  This study aims to determine the potential of bamboo vinegar as an organic material that can reduce the use of chemical fertilizers in the cultivation of pakchoy plants.  This study use  factorial 5 x 2 Randomized Block Design (RAK) with 3 replications.  The first factor is the amount of bamboo vinegar and NPK; 100% bamboo vinegar, 75% bamboo vinegar + 25% NPK, 50% bamboo vinegar + 50% NPK, 25% bamboo vinegar + 75% NPK, and 100% NPK.  The second factor is the frequency of fertilization; once and twice application.  The results showed that the use of bamboo  vinegar with 100% dose of concentration without the addition of NPK (10 ml/liter/plant) was able to produce the same height and number of leaves with the use of 100% NPK (2 g/plant).  The use of bamboo vinegar + NPK at 50% dose of concentration (5 ml / liter / plant + 1 gram / plant) at one time frequency of fertilization and the use of bamboo vinegar at 75% dose concentration (7.5 ml / liter / plant) + NPK  25% (0.5 gram/plant) at twice fertilization frequency was able to produce wet weight of canopy which has no differences with the use of 100% NPK (2 grams/plant). The application of bamboo vinegar can reduce the use of NPK chemical fertilizers in pakchoy cultivation depends on the frequency of fertilization.

Abstract

Tomato is one of Indonesia's export commodities that its production continues to increase from year to year. The high demand for tomatoes must be in the line with the guarantee of quality product until it reach to the consumers. The treatments given to maintain the quality of tomatoes were the maturity stages (green and turning) and the concentration of chitosan (2%, 3%, and 4%). The aim of this study is to obtain the information about the effect of maturity stages, chitosan consentration, and its interaction to the quality of tomatoes at 21 days of storage. The results showed that the ‘turning’ initial maturity stage showed a significantly higher weight loss and consumer preference leve and lower level of hardness than tomatoes with ‘green’ initial maturity. The 3% chitosan coating treatment had a significant effect on increasing the soluable solid content of tomatoes. The combination treatment did not give any significant interactions to the quality of tomatoes.
