Andisols in BBH, Gampong Aceh/Lembah Seulawah are derived from the parent material in the form of andesite - dacite volcanic rocks, rocky floats, tuffs and agglomerates in the quarter-time period of the Plistocene-Holocene (0.6 million years ago). Located at an altitude of 453 m above sea level, with oblique relief. The climate type of the Greater Aceh region is classified as climate type C, humidity regimes are classified as hick, and isohyperthermic soil temperature regimes. Characterized by: crumb soil structure; the consistency of wet soils rather closely; feels slippery (smeary); andik soil characteristics on the Bw horizon: C-organic 25% (1.42%); soil weight weight 0.90 g cm-³ (0.73 g cm-³); P-retention ≥ 85% (99.90%); and Alo + ½ Feo ≥ 2% (5.51%); Umbrik epipedon: horizon thickness AB ≥ 18 cm (18 cm); moist value 3 (3); C-organic ≥ 0.6% (3.95%); and KB pH 7 50% (10.62%).

In Aceh, Indonesia, low dryland crop yields entrench rural poverty. The lack of soil fertility information hinders the development of soil management programs to assist farmers to increase crop yield. This study identified soil-based constraints to production and management options to increase crop yield. We analysed 254 soil samples from 127 dryland cropping sites across Pidie, Bireuen, Aceh Besar and Aceh Barat districts for pH, soil organic carbon (SOC), total nitrogen (N), phosphorus (P), base saturation (BS) and cation exchange capacity (CEC). The dominant soils were Entisols, Inceptisols and Ultisols, with some Andisols and Mollisols. Overall, the CEC range was 10–60 cmol(+) kg–1 and available P was 0.5–702 mg kg–1 but most had poor fertility: SOC < 20.0 g kg–1, total N < 2.0 g kg–1, low basic cations and BS < 40%. The Ultisols and some Entisols and Inceptisols were acidic, with aluminium saturation >20% and available P < 6.5 mg kg–1. To sustainably increase crop yield, we concluded that these soils need lime where acidic, fertilisers for nutrients and stable carbon-rich amendments for system stability. This dataset will guide future agricultural research and development programs in Aceh to improve farmer practices and food security.

Availability of agricultural land is an important factor in ensuring food availability. Dryland such as Entisol has been used as an alternative for agricultural activities. Efforts to improve soil fertility on dryland can be done through the application of biochar and cow manure as soil amendments. This research was carried out on Entisoldryland located in the experimental site of The ACIAR Project, UniversitasSyiahKuala from April to September 2018. The study used a non-Factorial Randomized Block Design with 3 replications. The treatments weresoil amendments of rice husk and cocopeatbiochars, each was combined with cow manure. The doses used were 0 t ha−1 and 10 t ha−1 for each type of biochar, while cow manure was given at the doses of 0 t ha−1; 10 t ha−1; and 20 t ha−1. After the application of biochar and cow manure, the experimental land was planted with peanuts. The results showed that the application of biochar and cow manure were able to increase soil pH, organic C, total N, C:N ratio, available-P, and exchangeable-K. Both types of soil amendments were also able to give a significant result on the weight of peanut seeds, and increase the potential yield of peanuts by 3,96 t ha−1.

Abstrak.  Penelitian ini bertujuan mengevaluasi status kesuburan tanah pada beberapa jenis tanah di lahan kering Kabupaten Pidie, Provinsi Aceh. Penelitian ini dilaksanakan pada Juni hingga November 2015. Metode yang digunakan adalah metode deskriptif melalui survei di lapangan dan analisis di Laboratorium. Pengambilan sampel dengan melakukan pada areal survei secara sekuen bergerak yang diperkirakan sifat tanahnya berbeda berdasarkan ketinggian tempat, tanah diambil pada kedalaman top soil (0-20) cm. Parameter kimia tanah yang di analisis yaitu ; C organik, P2O5 total, K2O total, KTK, KB. Penentuan status kesuburan  berpedoman pada Pusat Penelitian Tanah PPT, Bogor (1995). Sampel tanah dianalisis di Laboratorium Penelitian Tanah dan Tanaman Fakultas Pertanian Universitas Syiah Kuala, Banda Aceh dan Laboratorium Penelitian Tanah Balai Besar Sumber daya Lahan Pertanian (BBSDL) Bogor. Hasil penelitian menunjukkan status kesuburan lahan kering  setiap jenis tanahnya adalah rendah. Parameter kesuburan yang menjadi kendala dalam status kesuburan tanah pada setiap jenis tanahnya di lahan kering Kabupaten Pidie dalah C-organik tanah dan Kejenuhan basa yang rendah.

The flood phenomenon in the Krueng Jreue Sub-Watershed, Aceh Besar, Indonesia, in recent years indicates biophysical damage to the land. Floods are influenced by factors from biophysical conditions of the land and high rainfall with small river cross-sectional capacity causing water to overflow the embankment and flood low areas. This research aims to analyse the flood vulnerability level in the Krueng Jreue Sub-Watershed, Aceh Besar, Indonesia. The results showed that flood vulnerability in the research area consisted of four classes: very vulnerable, vulnerable, moderately vulnerable and somewhat vulnerable, with each area averaging a score of 43.0, 38.8, 30.0 and 21.7. Types of land use that are particularly vulnerable to flooding are rice fields with a mean total score of 43.0. The vulnerable classes are found in settlements and moorings, with a total score of 42.0 and 36.5, respectively. While open land, shrubs, grasslands, primary forests and secondary forests are quite vulnerable to flooding, with a mean total score of 32.5 each: 30.0, 30.0, 28.0 and 27.0. The main components affecting flood vulnerability are rainfall, temperature and land use, while additional components are soil infiltration and slope. Mechanised hydrological disaster mitigation can be performed through optimisation of weir, embung, rorak and check-dam. Vegetative hydrological mitigation efforts can be performed by reforestation and agroforestry systems, maps and flood prediction. Non-technically, hydrological disaster mitigation efforts can be undertaken with legal policies, law enforcement, map creation and prediction of droughts and socialisation of legislation.
