Abstract

Mangga Kasturi (Mangifera casturi Kosterm) merupakan mangga endemik Kalimantan Selatan dengan status langka di alamnya berdasarkan IUCN-red list. Kasturi dengan masa juvenil yang panjang sehingga menyebabkan awal pembuahan yang lama. Penggunaan cahaya buatan dengan lampu LED-light emmiting diode diketahui dapat memperpendek juvenilitas karena meningkatkan efisiensi fotosintesis. Penelitian ini bertujuan untuk mempelajari perbedaan respon fisiologi dari bibit mangga Kasturi menggunakan lampu LED. Penelitian ini menggunakan rancangan petak tersarang dengan faktor utama lampu LED dan faktor kedua aksesi sebagai perlakuan yang disarangkan. Faktor utama terdiri dari tiga taraf yaitu LED merah, putih dan biru, sedangkan faktor kedua terdapat tiga taraf yaitu aksesi Cuban, Pelipisan, dan Kasturi. Penggunaan LED memberikan beberapa perbedaan respon terhadap kandungan klorofil, LED merah menunjukan nilai paling tinggi pada kandungan klorofil a, tetapi tidak ada pengaruh pada klorofil b dan rasio klorofil. Penyinaran LED biru menunjukkan nilai absorsi cahaya, konduktansi stomata, transpirasi, dan laju fotosintesis yang lebih tinggi pada aksesi Kasturi. Lampu LED biru meningkatkan kandungan glukosa, sedangkan lampu LED putih membuat kandungan fruktosa yang lebih tinggi dibandingkan lampu lain dan mempengaruhi ketebalan daun yang lebih tebal. Berdasarkan penelitian ini monokromatik LED memberikan pengaruh berbeda pada setiap karakter fisiologis, yang berpengaruh pada percepatan masa juvenil. Kata kunci: fotosintesis, fruktosa, glukosa, rasio klorofil

Abstract

Mangosteen (Garcinia mangostana L.) is the highly demanded fruit for export commodity from Indonesia. The biggest mangosteen production center in Indonesia is West Java Province that includes Purwakarta, Subang, Bogor, and Tasikmalaya contributing 90% of mangosteen production in West Java Province and 29% of national mangosteen production. The activities of mangosteen production in West Java Province have not been efficient yet, so the potential source of the fruit in West Java Province is not efficient enough to compete internationally. In order to have competitive advantages, supply chain management in mangosteen business was initiated in Bogor district in 2007 which integrated processes from receiving raw material to selling finished products. Needs identification and institutional structure in emerging supply chain of mangosteen in Bogor District were necessary to be carried out to improve the efficiency and effectiveness of the chain to achieve its objectives. In running its business processes, the member of the chain will be linked between each other. Supply chain needs will also be linked with each other. In this study, Intepretative Structural Modeling was used to describe the relationship between needs of the chain and relationships among the institutions in the chain.
