The use and management of land resource which are unsuitable with its land capability will cause physical, chemical and biological-damage to the land and will disturb its hydro-orological function. The damage of land resources in a watershed needs improvement to increase its land quality. Optimal land use management planning based on its land suitability and hydrological aspects become important and need to be applied. The objectives of the study were: 1) To analyze land use change at Cijalupang Watershed, 2) To evaluate SWAT capability to predict impact of land use change on the hydrologic characteritics of the watershed, and 3) To provide land use plan based on land quality and hydrologic characteritics of the watershed. The result showed that optimizing land use management by integrating GIS and SWAT model at the Cijalupang Watershed was capable to increase land quality of the watershed. This was shown by the improvement of its land use capability to create better hydrological condition by decreasing run off 2.1 % and increasing base flow and lateral flow 0.4% and 0.4% respectively.

Soil crust is a soil suface layer which is more compact, harder, and brittle when it is drier than underlaying material. The soil physical characteristics such as aggregate stability, bulk density and soil permeability rate are closely related to this soil crust process. An experiment was conducted to evaluate the effects of chicken manure doses and certain chicken manure with PAM (Polyacrile Amide) to soil aggregate, bulk density and soil permeability rate. The result of this research, were: 1) An incremental addition of chicken manure into soil increased soil aggregation percentage, soil stability and soil permeability rate, and 2) The combined incremental additions of chicken manure with PAM were found to be more effective than only an incremental additions of chicken manure, increasing the aggregation percentage, soil aggregate stability, from the soil one day drainage process, but another case in decreasing the bulk density permeability rate from the soil with the same process.

The fixation of P in soils is dynamic in nature and the behavior of P-fraction may change with time and cropping system. Application of organic matter to soil under upland soil have been reported to decrease P-sorption and increase P-desorpion. Pangalengan, South Bandung in west Java is one of the wet humid area of Indonesia that has high rain fall, covered mainly by tropical humid forest, volcanic area with fertile volcanic soil. The objective of this study were to describe and compare some chemical characteristic and behavior of P-fraction as a function of crops and slope of the land in the farming system in Pangalengan, South Bandung, West Java, Indonesia. Soil samples from the surface soil (0-20 cm) were collected from 15 locations based on different planted crops (Tea, Vegetables, Forest, and Intercropping crops), and level of slope of the land areas of Cihawuk village, District Kertasari, Kecamatan Pangalengan. The result of the study showed that C-organic content of soil samples from 15 location of planted crops was slightly high (3.04-4.92 %) but total Nitrogen was low (0.22-0.45 %), wih soil reaction (pH H2O) was slightly acids (5.60-6.30) and pH (KCl) was lower than pH(H2O) (4.60-5.70). The available-P was low (3.50 – 7.10 ppm), but the HCl 25 % P　from tea and vegetables location was higher than from forest and intercropping crops. Majority of P fraction from tea and vegetable location was Al-P fraction, but from Forest and intercropping crops was Ca-P fraction. The order of P fraction were Al-P > Ca-P> reductant soluble-P>Fe-P in tea and vegetables locations, but in the forest and intercropping were Ca-P> reductant-P > Al-P > Fe-P. However, The data showed that the total P (P-organic + P-inorganic) from tea and vegetables crop location was higher, and was dominated by inorganic form, than from forest and intercropping location was dominated by organic form. However, the slope did not affect the pattern of P-fractions and the sources of organic matter added or accumulated in those location formerly affected the amount and the pattern of P-fractions.

Aggregate stability is one of the important factors to be taken into account in controlling soil degradation. It influences soil ability to resist soil erosion. Therefore, it is necessary to have accurate measurement of aggregate stability that able to express well its resistance to dispersion. In this study, aggregate stability of various soil types were measured using different wet sieving time and aggregate size. Latosol Sindangbarang showed the highest aggregate stability index (ASI), followed by Podsolik Jasinga, Andosol Sukamantri, Lalosol Darmaga, and Regosol Sindangbarang Wei sieving time significantly affected AS!. The ASI decreased as wet sieving time increased The result also showed that different methods result in significantly different stability index. The method that used smaller size aggregates (< 2.83 mm) results in about 3 to 4 times higher stability index.

Forest destruction may affect forest hydrological functions either as a water regulator, maintaining the timing and distribution of river water flows, maintaining microclimate, or being able to protect the underlying areas from disasters such as floods. Revegetation is considered as an effort to improve the condition of forest and environment. The objective of this study was to examine the hydrological characteristics of soil under stands of Pinus (Pinus merkusii), Ugandan Mahogany (Khaya anthoteca), and Merawan (Hopea odorata Roxb). The method used is periodic measurement of soil physical variables. Our investigation reveals that hydrological and physical properties of soil under the stands were different. Within the same depth of soil, water content changed from the highest to the lowest in Pine (3.05%), Merawan Siput Jantan (2.40%), and African Mahogany (1.89%), respectively. The highest infiltration was 116.25 cm hour-1 under Pine stand, while the lowest was 24 cm hour-1 under Merawan Siput Jantan stand. The highest permeability was 13.27 cm hour-1 under Pine stand, while the lowest was 2.72 cm hour-1 under Merawan Siput Jantan stand. Dominated by clay, the soil texture was relatively similar in each stand. Further, the soil under the three stands were categorized as the soil hydrological group B.

Banjir di Cekungan Bandung terjadi setiap tahun di wilayah cekungan terendah seperti di Kecamatan Majalaya, Ciparay, Deyeuhkolot, Rancaekek, Bojongsoang, dan Baleendah, Kab. Bandung. Kajian analisis bahaya dan arahan mitigasi banjir merupakan salah satu upaya untuk mengurangi risiko dari bencana tersebut. Tulisan ini bertujuan untuk menganalisis bahaya dan menyusun arahan mitigasi banjir di wilayah Cekungan Bandung. Bahaya banjir diidentifikasi dengan menganalisis daerah bahaya banjir menggunakan Modification Topography Wetness Index (MTWI), sedangkan arahan mitigasi banjir dianalisis secara deskriptif dengan membandingkan hasil analisis bahaya dengan data penggunaan lahan. Hasil penelitian menunjukkan bahwa 2.36% daerah Cekungan Bandung termasuk kelas bahaya tinggi, 7.15% termasuk bahaya sedang, dan 90.49% termasuk daerah bahaya rendah. Kesadaran masyarakat terhadap pengelolaan lingkungan yang rendah juga menjadi salah satu faktor penyebab banjir di Cekungan Bandung. Pada zona prioritas arahan mitigasi banjir dilakukan dengan pembuatan saluran drainase tambahan untuk mengalirkan air dari cekungan terendah. Selain itu, perlu dilakukan pengendalian penggunaan lahan dengan cara penegakan hukum terhadap penggunaan lahan yang tidak sesuai Rencana Tata Ruang Wilayah (RTRW) dan dilakukan rehabilitasi hutan dan lahan pada lahan kritis di DAS Citarum Hulu.

Differences in productivity were observed in various land units on pineapple plantation in Central Lampung even with the same land and fertilization management. The nature of soil chemical and physical variability were thought to be the cause of these differences. The study was aimed to compare chemical and physical soil properties in land units with different pineapple productivity. Soil samples were taken from 6 units of land with low and 3 units of land with high productivity. The soil chemical properties meazured include available P and K, potential P and K, total N, pH, organic C, exchangeable cations, and available micro nutrients. The soil physical properties determined include bulk density, soil texture, and penetration resistance. The data was analyzed using T-test and correlation. The T-test revealed that the high productivity soils were significantly lower in available P, potential P, total N, and available Zn compared to the productivity soils. Furthermore, the high productivity soils were significantly lower in bulk density and penetration resistances both vertically and horizontally. There were significantly negative correlations between pineapple yields with potential P, available Zn, bulk density, and penetration resistance both vertically and horizontally. Overall analyses indicating that the physical properties were more as productivity determinant, particularly bulk density and penetration resistance, compared to the chemical properties. The chemical properties were more as residual conditions after nutrient absorption process to support pineapple productivity. In order to increase the productivity, it is necessary to manage the soil to lower bulk density and penetration resistance. Keywords: Crop management, nutrient management, penetration

Endofit adalah bakteri atau cendawan yang secara alami berasosiasi dan mengolonisasi jaringan internal tumbuhan tanpa menimbulkan dampak negatif pada inangnya. Sejumlah endofit bermanfaat bagi tanaman karena berperan sebagai pemacu pertumbuhan ataupun sebagai pengendali hayati. Tujuan dari penelitian ini adalah untuk menyeleksi dan mengidentifikasi endofit yang berpotensi sebagai pemacu pertumbuhan dari lima varietas tebu PT Gunung Madu Plantations Lampung. Sebanyak 82 isolat yang telah lolos dalam uji reaksi hipersensitif dan hemolisis diskrining dalam dua tahap. Tahap pertama dilakukan di laboratorium dengan menginokulasikan endofit pada benih padi dan mengevaluasi kecambahnya setelah umur tujuh hari. Isolat yang lolos pada tahap pertama dilanjutkan ke tahap kedua dengan menginokulasikannya pada bibit tebu dalam skala semi lapangan. Pertumbuhannnya tanaman tebu dievaluasi hingga 6 minggu setelah tanam. Sebanyak 9 isolat bakteri dan 9 isolat cendawan terindikasi sebagai pemacu pertumbuhan pada tahap pertama, tetapi hanya dua isolat bakteri dan satu isolat cendawan yang konsisten pada pengujian tahap kedua. Identifikasi molekuler ketiga isolat tersebut dan pencocokan sekuens pada BLAST menunjukkan bahwa isolat N12 yang terisolasi dari akar GMP3 mirip dengan Bacillus safensis 100%, L16 yang terisolasi dari daun GMP3 mirip dengan Domibacillus robiginosus 99%, dan C78 yang terisolasi dari batang PS48 mirip dengan Cladosporium cladosporioides 99%. Ketiga isolat tersebut mampu menghasilkan auksin, sitokinin, and giberelin dengan kecenderungan B. safensis lebih tinggi dibanding dua lainnya.

Penggunaan Biochar dan Dekomposer dalam Proses Pengomposan Limbah Kulit Buah Kakao serta Pengkayaan Mikrob Pelarut Fosfat (MPF) untuk Meningkatkan Kualitas Pupuk Organik: Application of Biochar and Decomposers to the Composting Process of Cocoa Husk and Enrichment Using Phosphate Solubilizing Microbe to Improve the Quality Organic Fertilizer Haryanti Haryanti; Iswandi Anas; Dwi Andreas Santosa; Kurnia Dewi Sasmita

The use of cocoa husk waste by farmers is not optimal. In general, farmers only dispose of or immerse cocoa husk waste without processing it into quality organic fertilizer. This study aims to determine the influence of biochar and decomposers in accelerating the process of composting cocoa husk waste and improving the quality of organic fertilizers, and the effect of adding Phosphate Solubilizing Bacteria (BPF) to organic fertilizer derived from cocoa husk waste on the growth of cocoa seedlings (Theobroma cacao L.). The first phase of the research was carried out a factorial 2 factor design in the Completely Randomized Design i.e. Biochar (without biochar and 10% biochar from the dry weight of organic fertilizer materials), and Decomposers (without decomposers and decomposers of 100 g kg-1 of organic fertilizer). The second phase of the study used a 3-factor factorial design in a Completely Randomized Design i.e. type of organic fertilizer (without organic fertilizer, organic fertilizer, organic fertilizer and biochar), inoculant Phosphate Solubilizing Bacteria (BPF), (without BPF inoculants, BPF A inoculants and BPF B inoculants), and dose of P fertilizer (without P fertilizer, SP-36 fertilizer 1 g P2O5, SP-36 fertilizer 2 g P2O5, and natural phosphate fertilizer 2 g P2O5). The results showed that the administration of biochar and decomposers did not accelerate the composting process. Provision of biochar and decomposers increases levels of humic acid. Giving natural phosphate 2 g P2O5 / 2.2 kg BKM increases the height growth of cocoa seedlings. Application of organic fertilizer with biochar or without biochar on the inoculant treatment factors of BPF A and BPF B significantly increased the diameter of the cocoa seedling stem. Application of organic fertilizer increases the stem diameter, plant height, number of leaves of cocoa seedlings, root dry weight and dry weight of stem of cocoa seedlings.
