Analysis of Land Suitability for the Development of Porang (Amarphopallus ancophillus ) Plants in Lewa Sub-Regency, East Sumba Regency

Abstract

Lewa sub-district is one of the sub-districts in East Sumba Regency, which has dry land that can be maximized for the development of porang plants and development purposes; information on the potential of porang plantations is needed. This study aimed to determine the biophysical characteristics of the land and the land suitability class of porang plants. The analytical method used was the matching method by comparing the land characteristics and plant growth requirements and the overlay method. The matching results show that the land characteristics in Lewa Subdistrict are class S1 (Very suitable), covering an area of 26.220,209 ha and Class S2 (quite suitable), covering an area of 3.608,523 ha. Limiting factors in this area are water availability (OA) such as drainage, nutrient retention (nr) such as CEC and pH, and erosion hazards (eh) such as slope.

Land suitability in sustainable cultivation practices for porang (Amorphophallus oncophyllus L.) in Pasuruan Regency, Indonesia

“…Pengambilan sampel tanah dilakukan dengan metode purposive sampling sesuai dengan penelitian sebelumnya (Nimpuna et al, 2022) Berdasarkan pernyataan tersebut dipastikan bahwa suhu di wilayah Desa Sumberejo sesuai untuk penanaman tanaman porang. Berdasarkan penilaian curah hujan rata-rata tahunan (perhitungan 5 tahun) memiliki rerata curah hujan sebesar 1,994 mm/tahun dan menurut Apu et al (2022) cocok untuk tanaman porang yang membutuhkan CH sebesar 1,200-2,000…”

“…Tanaman porang merupakan jenis tanaman umbi-umbian termasuk keluarga Araceae dan kelas Monocotyledoneae (Refnizuida, Girsang, Sembiring, & Luta, 2022). Porang dapat dijadikan salah satu jenis tanaman alternatif sumber bahan pangan karena memiliki kandungan gizi seperti kandungan karbohidrat, protein, serat dan lemak (Apu, Jawang, and Nganji, 2022). Kandungan karbohidrat dari umbi porang banyak digunakan dalam industri kertas, tekstil, cat, bahan negatif film, bahan isolasi, pita seluloid dan bahan kosmetik (Sholiha, 2021).…”

Financial Prospects of Porang Cultivation in East Lombok Regency, Indonesia

“…Based on data on the potential land area that can be cultivated by porang in East Lombok Regency consisting of the potential area of Community Forest (HKm) = 1,230 ha, excluding HKm = 28,827 ha, and the total land potential is 30,057 ha. Estimation of the potential amount of production and income can also be done by using assumption data based on experiences that have been carried out by farmers and porang business actors from other regions in Indonesia (Apu et al, 2022;Izza et al, 2022;Utami, 2021). Estimation calculations based on the potential land area that can be planted with porang in East Lombok Regency obtained an estimated total production of 601,140 tons in one growing season with an estimated income of 1.89 trillion with a potential profit of 732 million.…”
