Abstract

Tomato has the characteristics natural to damage. Damage fruits are caused by destitute of fruit quality and sensory attributes. The loss of tomato production on harvest in developing countries reached 50% due to the long duration of tomato distribution. Servo varieties of tomatoes are in demand by farmers because of their genetic advantages, high productivity, and abundant fruit weights. The shortage of servo varieties of tomatoes is the short shelf life of fruit, which is seven days after harvest. Short shelf life is influenced by fruit thickness and fruit hardness. In improving the quality and shelf life of tomatoes, potassium (K) nutrition plays a role in photosynthetic translocation, strengthens the cell wall, and involved in the lignification process of sclerenchyma tissue. Tomatoes, as climacteric fruits have a high respiration rate influenced by ethylene. Ethylene production can be inhibited by calcium chloride (CaCl2) application by strengthening the cell wall mechanism, cross-link with pectin, and increase the cell wall regeneration can change the texture of the fruit become harder, and it reduces sensitivity to physiological damage. Based on the treatment of this research, the quality and shelf life of servo varieties of tomato is increased.

Abstract

Impor gula terus dilakukan setiap tahun oleh Pemerintah Indonesia untuk memenuhi kebutuhan dalam negeri yang mencapai angka 3,5 juta ton/tahun, sedangkan produksi gula nasional hanya sekitar 1,5 juta ton. Penyebab dari masalah ini antara lain adalah rendahnya produktivitas lahan dan rendemen gula rata -rata nasional yaitu di bawah angka 6% (Ditjed Industri Agro dan Kimia, 2009). Untuk memenuhi kebutuhan gula  nasional, pemerintah menargetkan menaikkan rendemen tebu rakyat menjadi 8,4% di tahun 2014 dan menaikkan produksi gula  konsumsi menjadi 3,57 juta ton tahun 2014.  Salahsatu penyebab rendahnya rendemen/kadar gula adalah pemenuhan nutrisi tanaman  yang  tidak  akurat, terutama  pemenuhan unsur N.  Secara  fisiologis, tanaman tebu membutuhkan suplai N dalam jumlah yang tepat untuk dapat menghasilkan rendemen tinggi. Sampai hari ini cara pemupukan tebu masih menggunakan paket dosis anjuran yang dikeluarkan oleh pabrik gula (PG). Cara ini tidak memperhitungkan N yang terkandung di dalam tanah, padahal tanah mengandung N yang sangat bervariasi. Tanah di daerah Semboro, sebagai contoh, mengandung N mulai dari 217 sampai 532 kg/ha. Penelitian berupa percobaan lapang yang  menggunakan varietas Bululawang yang memiliki potensi rendemen 15% dan varietas ini mendominasi areal tebu di Jawa Timur.  Penelitian menggunakan Rancangan Acak Kelompok Lengkap (RCBD) dengan 6 taraf suplai N yang masing-masing diulang 4 kali. Taraf suplai N yang diperlakukan adalah:   231; 252; 273; 294; 315; dan 336 kg N/ha. Pengertian suplai adalah pemenuhan kebutuhan nitrogen yang bersumber dari N tanah dan N pupuk, sehingga untuk menetapkan besar suplai, N tanah dianalisis terlebih dulu dan kekurangannya ditambahkan dalam bentu pupuk. Tujuan penelitian adalah untuk mendapatkan angka kebutuhan nitrogen tanaman tebu bahan baku industri gula berkadar gula tinggi. Berdasarkan data yang dihasilkan maka dapat disimpulkan bahwa, untuk mencapai kadar gula tinggi tanaman tebu membutuhkan nitrogen sebanyak 315 kg/ha. Kata kunci: suplai Nitrogen, kebutuhan Nitrogen, kadar gula, bululawang.

Abstract

Vegetable quality is determined by the physical properties, chemistry, color, and taste. Since increased public awareness of health, their demand on food quality has alsoincreased. Chemical properties of vegetables include: level of nitrate, pesticide residue andheavy metal content. The purpose of this paper is to provide information to Indonesianvegetables stakeholder, the European markets impose strict conditions on levels of nitratevegetables. The method used is the study of literature from a variety of credible sources. Inthe human?s stomach is reduced nitrate to nitrite, then nitrite reacts with amines to formnitrosamine compound. Nitrosamine is known as a very potential carcinogenic compound,with risk of 90%. Statistically, 72.4% of daily nitrate intake originated from vegetables,equal to 35.7 mg/day. Besides forms nitrosamine, nitrite couse methemoglobinamie (babyblue syndrome). Nitrate is very serious threat to human health, so that the WHO limit the maximum daily nitrate intake do not exceed 220 mg (Scharpf and Wehrmann, 1991). To protect their citizen against nitrate hazard, European government are agreed to limit themaximum nitrate content in vegetables. Each species of vegetable and Country has differentnitrate limit. Indonesian?s vegetable contain high nitrate level and difficult to reducebecause there is no technology have been developed to quantify N supply to achieve lownitrate content. Growers in developed countries (Europe, USA, Japan, and Canada) applyN-mineral Metode to maintain nitrogen supply and nitrate content. Wijaya (2012) haveanalyzed 5 species of vegetables (spinach, pachoy, cabage, lettuce and chinakol) resfectivlycontain 6.427, 3.915, 1.847, 1.553, and 704 mg/kg FS). Acording to these nitrate contentand nitrate limiting role of European Countries, very hard for Indonesia to exportIndonesian vegetables to Europe.

Abstract

Intensive nutrient managements for crop production are one of agriculture management strategies that are not yet widely adopted in most third world countries.Precise N Fertilization as a part of intensive nutrient managements is a great way tomanage input efficiency; yet, the technology is feasible enough for farmers to apply, inorder to increase the farm product quality while improve access in modern market.Nitrogen (N) required for plant growth and development in large numbers, but the plant isonly capable of absorbing an average of less than 50% N provided through conventionalfertilization. Greenhouse gases emissions are increasing mostly because of expanding useof N fertilizers, while the carcinogenic effect of N residue on farm products is a dangerousrisk for human health. By increasing the awareness on health and environmental effects forfarm products especially concerning precise N fertilization, consumer will get healthbenefit while producer will get an added value for their products. Thus, by applying betterinput efficiency farmers could simultaneously increase the price while meeting the higherconsumer demands even with gradually stricter standards in term of farm product qualityand market requirements.
