Land-use change and lack of conservation in Bogowonto Watershed area have caused land degradation due to erosion and landslides. The rate of land degradation can be measured through the morphological characteristics of the soil and landscape. This study aimed to identify the relationship between the morphological characteristics of the soil and the rate of land degradation in Bogowonto Watershed area. The research framework initiated from the interpretation of thematic maps, surveys and field observations, and verification using land degradation assessment software. Sample points were determined using a stratified random sampling method. In general, land degradation is affected by slope, limited soil development, suboptimal conservation measures, and land-use change. Particularly, land degradation is affected by the type of landscape and the morphological characteristics of the soil. Volcanic hilly landscapes show a degradation rate of fine to very fine, characterized by thick soil depth (>60 cm), generous root distribution, loamy textured soil, fine soil particle size (Ø <0.002 mm), and good soil structure. The distribution of easily weathered volcanic ash causes volcanic hills to have thick and fertile soil characteristics. Quaternary-tertiary volcanic transition landscapes show a degradation rate of damaged to heavily damaged, characterized by thin soil depth (<60 cm), limited rooting, dominant coarse fraction (Ø 2–0.05 mm), and contact with fields lithological discontinuity. The data obtained provide information on the morphological characteristics of the soil and land degradation in Bogowonto Watershed area. The results of the study can also be used as a formulation for the conservation of Bogowonto Watershed area.

Activities of Old Lawu volcano in the past resulted in various soil development in the south side of the volcano, especially in the area of the east side of Wonogiri and west side of Ponorogo, that located in the Java island. This area is also famous as herbal crops producer for raw materials of traditional herbal medicine industry. The purpose of this research is to identify the process of exposure of the parent materials in the Old Lawu volcanic environment, the development of the soil parent materials, and the mineralogy variation. Four Sites with different geological formation were observed, and each Site was selected for soil profile identification on the process of weathering of rocks. All layers of each profile were then sampled and then sand fraction of the fine earth particle was determined for the mineral type using X-ray diffraction (XRD). The results showed that materials of the Old Lawu volcanic activity that was of quaternary period had sized material of gravel, sand, silt, and clay. These materials were then exposed and undergone the process of weathering, transportation, and sedimentation according to the landform at that period. The development of soil as geoheritage in this region was influenced by the material size, landform, and settling process. There are four typologies of the environment on the soil development at the present study, there are: (1) Soil that developed in the inter-fluvial basins is characterized by thick soil and a clear horizon differentiation process as a feature of maturity stage of soil development. (2) Soil developed on the slope of hill area is characterized by shallow in solum and it is in early-stage soil development. (3) Soil developed on the volcanic materials that were transported and sedimented in the river environment is characterized by the thick soil above the layered fine size parent material with a variety of color. (4) Soil developed on the tertiary breccia showed early soil development.

Meningkatnya permintaan masyarakat akan sayuran mendorong petani untuk meningkatkan produksinya. Upaya yang dapat dilakukan untuk meningkatkan hasil panen antara lain penggunaan pupuk. Pemupukan dengan pupuk kimia merupakan alternatif yang sering dilakukan, namun kelangkaan pupuk kimia di pasaran membuat pupuk tersebut semakin mahal, sehingga perlu dicari alternatifnya. Pembuatan pupuk organik dari limbah tanaman merupakan salah satu alternatif yang memungkinkan, dengan teknologi EM yang akan mempercepat proses produksi pupuk. Kegiatan pengabdian ini dilaksanakan di Kelurahan Kalumata Kota Ternate Selatan dengan tujuan membantu petani mengelola limbah pertaniannya dengan memanfaatkannya sebagai pupuk organik. Peserta pengabdian adalah anggota Kelompok Petani Sayur "Masure". Metode yang digunakan adalah metode penyuluhan dan demonstrasi. Kegiatan dilakukan secara langsung dengan anggota kelompok tani, diawal dan diakhir kegiatan dilakukan penilaian untuk mengetahui tingkat pengetahuan peserta pengabdian. Hasil evaluasi menunjukkan bahwa pengetahuan dan pemahaman anggota kelompok tani “Masure” mengalami peningkatan. Hal ini tercermin dari peningkatan nilai tes akhir, dimana sebagian besar anggota mendapat nilai di atas 80. Peserta dalam kegiatan ini juga dapat memproduksi pupuk organik sendiri dengan memanfaatkan limbah organik dari sisa tanaman pasca panen dan kulit buah.

One of the indicators of land productivity assessment is soil fertility. The causes of infertile soil have been widely reported. This study aimed to evaluate soil fertility using the Soil Fertility Capability Classification (SFCC) approach and to determine the relationship between soil morphological and physiochemical properties and soil fertility. The research was conducted in North Galela Sub-district, North Halmahera Regency. The research framework began with the interpretation of thematic maps, surveys, field observations, and the making of soil fertility evaluation maps. Soil sampling was carried out based on the stratified random sampling method and supported by laboratory measurements according to USDA international standards. The research result showed that the research area had 14 soil fertility statuses. The fertility classes having the most significant limiting factor were loamy texture (Ø<0.002 mm), rock surface, gravel subsoil, moderate salinity (0.2-0.4 mS cm-1), low exchangeable K (<20 cmol(+) kg-1), and sloping slope (8%) with Lithic Haprendolls type and loamy texture (Ø<0.002 mm), subsoil >15% rock outcrop, moderate salinity (0.2-0,4 mS cm-1), Na saturation >15%, and a rather steep slope (14%) with Lithic Eutrudepts type. Both of these classes have a top layer texture, and the bottom layer contains clay <35%, with limiting factors of hard layer inhibiting root to a depth of 50 cm, extremely low nutrient reserve, low electrical conductivity (EC) and high Na. The limiting factors found in North Galela Sub-district were hard root-restricting layer, exchangeable K, electrical conductivity, Na saturation, slope, and gravel.

Sehingga pada penelitian kali ini akan membahas mengenai kajian jenis tanah sebagai bahan dasar pembuatan karya seni patung dan gerabah dalam perspektif ilmu tanah. Metode yang digunakan pada penelitian ini adalah metode deskriptif kualitatif pada jenis tanah dalam perspektif ilmu tanah sebagai objek kajian peneltian. Peneltian ini bertujuan untuk mengkaji jenis tanah yang baik untuk digunakan sebagai bahan dasar pembuatan karya seni patung dan gerabah yang sesuai dalam perspektif ilmu tanah. Hasil dari penelitian ini menunjukkan bahwa tanah yang baik untuk digunakan pada pembuatan karya seni patung dan gerabah berupa tanah berjenis alfisols yang memiliki ciri berupa warna kemerahan seperti merah bata yang dicirikan oleh tingginya kandungan besi di dalam tubuh tanah. Tanah dengan jenis alfisols memiliki komposisi yang didominasi oleh fraksi debu dan liat yang keberadaanya berada di kedalaman 40cm hingga kebawah, yang dikarenakan terjadinya proses pencucian kandungan kimia secara intensif dalam jangka waktu tertentu oleh air dari atas permukaan yang membawa fraksi liat sehingga tertahan dan mengendap pada lapisan 40cm dibawah permukaan tanah.In the manufacture of works of art basic materials are required that are good and meet standards as materials that can be used to make works more durable and can be used according to their value function and function of use. Works of art as a whole must follow and use these rules without exception in the manufacture of sculptures and pottery which generally use earth based materials. So that this research will discuss the study of soil types as the basic material for making sculptures and pottery works from the perspective of soil science. The method used in this study is a qualitative descriptive method on soil types in the perspective of soil science as an object of research study. This study aims to examine the types of soil that are good for use as basic materials for making sculptures and pottery works that are suitable from the perspective of soil science. The results of this study indicate that a good soil for use in the manufacture of sculpture and earthenware works of art is in the form of alfisol type soil which has a reddish color like brick red which is characterized by high iron content in the soil body. Soils of the alfisols type have a composition dominated by silt and clay fractions which are located at a depth of 40cm to the bottom, which is due to an intensive process of leaching the chemical contents over a certain period of time by water from above the surface which carries the clay fraction so that it is retained and settles in layers 40cm below ground level.

Pengembangan lahan tegalan di Kelurahan Sasa Kecamatan Ternate Selatan melibatkan pengolahan tanah secara intensif sehingga memiliki struktur tanah yang renggang dengan porositas yang tinggi. Demikian juga dengan kondisi alami tanahnya yang bertekstur lempung dan berpasir dapat menyebabkan meningkatnya laju infiltrasi serta turut menentukan ketersediaan air yang ada. Penelitian ini bertujuan untuk mengetahui kapasitas infiltrasi, infiltrasi kumulatif dan karakteristik tanah yang memengaruhi kapasitas infiltrasi. Penelitian ini menggunakan metode percobaan lapangan dengan menggunakan double ring infiltrometer dalam mengukur laju infiltrasi. Analisis data meliputi laju infiltrasi aktual, kapasitas infiltrasi dan infiltrasi kumulatif. Hasil penelitian menunjukkan lahan tegalan dengan olah tanah minimum (Tg-Otm) memiliki kapasitas infiltrasi lebih rendah dibandingkan dengan lahan tegalan tanpa olah tanah (Tg-Tot) dan lahan tegalan dengan olah tanah intensif (Tg-Oti), demikian juga dengan infiltrasi kumulatifnya. Kondisi tersebut terjadi karena lahan tegalan dengan olah tanah minimum (Tg-Otm) memiliki tekstur tanah agak halus, bahan organik tanah rendah, berat volume tanah lebih tinggi, berat jenis partikel lebih rendah, porositas tanah sedang, kadar air tanah lebih tinggi dan permeabilitas tanah agak lambat.
