Abstract

Petunia (Petunia × hybrida) sebagai tanaman hias berbunga umum digunakan tanaman pot dan hamparan. Memiliki berbagai macam varian warna, pola, bentuk dan ukuran menjadi nilai tambah. Aplikasi dilapang, tidak semua tanaman hias memperoleh intensitas cahaya matahari yang seragam. Tujuan penelitian ini adalah untuk mengetahui tanggapan dua tipe tanaman petunia grandiflora dan multiflora pada fase vegetative dan pembungaan. Penelitian dilaksanakan di Desa Girimoyo, Kecamatan Karangploso, Kabupaten Malang pada bulan Maret - Juni 2015. Penelitian ini menggunakan rancangan petak tersarang dua faktor. Faktor pertama adalah naungan dengan empat taraf yakni 0% (N0), 25% (N25), 50% (N50), 75% (N75). Tidak terdapat interaksi antara tipe petunia dan level naungan di seluruh parameter pengamatan. Peningkatan level naungan berpengaruh pada seluruh parameter pengamatan. Fase vegetatif dibanding tanpa naungan, pemberian naungan menyebabkan pemanjangan hingga 37%, penambahan luas daun hingga 93%, peningkatan indeks klorofil hingga 75%,  penurunan jumlah daun hingga 29%. Fase generatif dibanding kontrol, naungan menyebabkan perlambatan bunga hingga 13 hari, penambahan diameter hingga 5%, penurunan jumlah bunga hingga 73%. Berdasarkan parameter jumlah bunga, petunia merespon positif pada naungan 25% dengan nilai intensitas cahaya matahari sebesar 84.000 lux dibanding tanpa naungan. Tipe tanaman berpengaruh nyata seluruh parameter kecuali jumlah daun dan saat inisiasi bunga pertama. Berdasarkan jumlah bunga, tipe multiflora memiliki jumlah bunga lebih banyak dibanding tipe grandiflora.

Abstract

Urban agriculture (UA) and urban-peri-urban agriculture (UPA), is one of the approaches to improve sustainability of urban food system. Urban agriculture can increase access to fresh food for the community, by shortening the food supply chain. There are many impacts from ecological, economic, social dimensions. However, it is undeniable that urban agriculture also brings other negative impacts in various dimensions. Which directly or indirectly affect the sustainability of urban agriculture. Many urban agriculture have low sustainability. Malang City itself has the potential for urban agriculture. At least there are 7 types of urban agriculture in Malang City, namely (1) wetland/irrigated agricultural land, (2) Rainfed dryland farming, (3)recreational activity, (4) community gardening, (5) commercial farming, (6) agro-educational tourism, (7) institution. The purpose of this study is to assess the sustainability status of each type of urban agriculture. A quantitative approach, using the multidimentional scaling method and RAPHYTON tools was used to analyze the data. Primary data were collected from expert informant interviews, supporting informants, field surveys and observations. The results of the analysis showed that the sustainability level of urban agriculture various types in Malang City is generally in the moderately sustainable category. The ecological dimension of irrigated agricultural land is categorized as unsustainable. Conversely, the highest sustainability status (categorized as sustainable) is achieved by agro-educational tourism type agriculture in the social dimension. This research also suggests attributes that leverage the sustainability status of each dimension. One of them is the application of integrated agriculture to achieve ecological sustainability.
