Abstract

The characteristics and quality of land resources are important things that must be considered in the planning, utilization and management of land for agricultural purposes. The purposes of this research were to describe land characteristics and quality, and to determine the suitability class, subclass, and limiting factors for clove (Zysygium armoticum), banana (Musa sp), and cassava ( Manihot esculenta Crant.) crops in Wai Ela Watershed. The method used in this study was a survey with land units as a fieldwork map which resulted from overlying four components, namely slope class, lithology formation, soil, and land uses. Field data collection was conducted following the observation lanes at 15 selected sample areas representing 72 land units. Data analysis was carried out by using a geographic information system (GIS), involving: (1) SRTM image analysis to produce topography class, (2) maps overlay to produce land units, and (3) attribute data processing to produce land suitability class. The study results showed that the land suitability for clove consisted of the suitable class of S2 (21.91 ha) and S3 (327.89 ha), and not-suitable, N (1069.85ha), with limiting factors being flooding, soil depth, and slope steepness. Land suitability for bananas consisted of the suitable class of S3 (501.70 ha), and not-suitable, N (686.99 ha) with limiting factors being flooding, erosion, and slope steepness; whereas land suitability for cassava consisted of the suitable class of S3 (501.70 ha) and not-suitable, N (917.96 ha), with limiting factors being flooding, slope steepness, and erosion.

Abstract

Forest areas are designated as protected forests if they function as a provider of clean water reserves, erosion control, city lungs or other functions. Disruption of forest land resources has an impact on changes in the physical properties of the soil and soil degradation due to erosion. Objectives of this study were: 1) to examine the relationship between soil physical properties, 2) to determine soil degradation due to erosion, 3) to examine the relationship between soil physical properties and the level of soil degradation due to erosion, 4) to determine recommendations for land rehabilitation. Research observations were made based on 15 sample areas representing 212 land units. All analyzes were carried out based on Geographic Information Systems (GIS). The physical properties of the soil studied included texture, structure, pore distribution, permeability, particle density and oven dry mass density; whereas soil degradation analysis was based on RUSLE: A=RKLSCP (Renard et al., 1997), and correction of the erosion model A=0.2547RKLSCP (Talakua S.M. and Osok, 2017. The rehabilitation recommendations analyzed were erosion tolerance, potential erosion and CP-maximum. Study results were: 1) The correlation between physical properties was significant (P-value = 0.000*-0.018*) with a positive correlation coefficient (0.163-0.999) and negative one (0.199-0.998); 2) The average erosion rate was: light 3.60 t/ha/year (1425.20 ha), moderate 32.03 t/ha/year (410.28 ha), heavy 108.95 t/ha/year (946 .2 ha), very heavy 426.83 t/ha/year (457.44 ha); 3) There was a significant correlation between the physical properties of the soil and the amount of erosion with a P-value = 0.000*–0.029* with a positive (0.152-0.161) and a negative (0.150-0.151) correlations; 4) Recommendation for rehabilitation are agroforestry patterns combined with tillage and planting of plants according to contour lines on slopes of 0–8%, planting grass in strips, planting low ground cover on high density plantation crops and maintaining secondary and primary forests.

Abstract

Bencana bisa terjadi kapan saja dan dapat menimbulkan risiko dan  dampak yang besar terhadap kehidupan manusia. Di lokasi pengabdian masyarakat setiap hujan disekitar permukiman masyarakat  mengalami banjir/genangan, sehingga dibutuhkan upaya mengatasinya.   Tujuan utama dari Kegiatan ini  adalah sebagai berikut: Mengurangi resiko/dampak yang ditimbulkan oleh  bencana banjir pada permukiman penduduk. Kegiatan pengabdian kepada masyarakat ini dilaksanakan di Desa Wayame Kecamatan Teluk Ambon Kota Ambon dengan melibatkan peserta adalah masyarakat yang termasuk dalam  kelompok Proklim Dusun keranjang. Metode kegiatan yang digunakan untuk mencapai tujuan yang diharapkan adalah: Penyuluhan bagi masyarakat setempat, Pelatihan dengan membuat satu contoh biopori, dan  pembuatan biopori di area permukiman Kawasan banjir/tergenang.  Pembuatan Biopori  sangat bermanfaat bagi lingkungan masyarakat, selain mengatasi genang air atau banjir pada permukiman warga, juga dapat menjadi wadah tempat pembuatan pupuk organik untuk kebutuhan tanaman, serta mengurangi sampah di lingkungan. Dampaknya bahwa setiap hujan tidak lagi terjadi genangan, dan pupuk organik dan lubang biopori tetap tersedia bagi pertumbuhan tanaman pekarangan.
