Sweet potato is the main food resources for human life besides that of rice. An experiment to find out the effect of weeding with two kinds of fertilizer on the growth of yield sweet potato (Ipomoea batatas L.) was conducted at UB Agro Techno Park, Jatikerto, Kromengan, Malang, East Java, from April until to 2017. The experiment used a randomized block design with six treatments consisting of G1 (organic fertilizer + weeding 15 days after planting = DAP), G2 (inorganic fertilizer + weeding at 15 DAP), G3 (organic fertilizer + weeding at 15 and 30 DAP), G4 (inorganic fertilizer + weeding at 15 and 30 DAP), G5 ( organic fertilizer + weeding 15, 30 and 45 DAP), G6 (inorganic fertilizer + weeding at 15, 30 and 45 DAP) with three replications. The results showed that weeding three times (15, 30 and 45 DAP) significantly reduced the dry weight of weeds, improved the growth and yield of sweet potato with two kinds of fertilizers.

In recent years, GIS and Remote Sensing technology has played a vital role in studying urban growth and development. This study is aimed to assess the effects of urban expansion on the surrounding land uses using GIS and Remote Sensing in Debre Tabor Town. Remote sensing data or products such as Aerial photograph (1984), Quick Bird Satellite Image (2000), and Aerial photograph (2016) were used to compute spatial or temporal changes of land use land cover due to urban expansion. ERDAS Imagine and Arc GIS software were used to analyze, model and map the data. The study revealed a significant change in urban boundary and urban land-use land cover between 1984 and 2016. The urban boundary expansion rate between the years 1984 and 2000 was 69.06%, higher than the rate experienced thereafter to the year 2016 (18.86%). However, for the last thirty-two years, between 1984 and 2016, the overall boundary increasement of almost eighty one percent (81.4) was very magnificent. The study also indicated that the area experiencing rapid increase in built-up areas (80.93 %), and agricultural land (23.81%). However, sharp decrease of forest by 36.07%, and open land by 65.02% was seen in the same periods of years. Built-up area expansion was found to have increased by expanding the urban boundary at the expense of open land, agricultural land, and forests. Therefore, integrating GIS and remote sensing technology for urban expansion mapping is a worthy method. Hence, it is recommended that it will be cost effective if the results of this study will be incorporated into ongoing urban planning and land use by concerned bodies.

Environmental degradation, which is caused by the quarry, is a complex problem. The site of the quarry within an agricultural land and forest makes land become critical. Rehabilitation of the area can be conducted by reclamation. Revegetation using local species is no better than pioneer species. Based -on Indonesian regulation-in Permenhut P.4/Menhut-II/2011, revegetation using fast-growing species is important for a precondition before enrichment using climax species, so then it needs an evaluation of land suitability for the fast-growing species. The study of revegetation was conducted at quarry clay which the characteristics of this study were description and exploration with field survey supported by laboratory analysis. Data obtained were analyzed by giving weights and scores of species characteristics to decide selected species of vegetation, then the soil characteristics and qualities were matched with species growth requirements. The results showed that jabon (Anthocephallus cadamba) and sengon (Falcataria moluccana) are selected species for revegetation. Land suitability classes of jabon and sengon are not suitable (N) and land suitability of jabon and sengon can be increased to be marginally suitable (S3) by reclamation using potting system that includes building drainage, improvement of depth, soil pH, application of fertilizer, dolomite, and gypsum, application of grass mulch and collecting large rocks for making the terrace.

Application of Agrobacterium sp. I30 and vermicompost to suppress lead (Pb) uptake by rice in Pb polluted soil Karisma Ana Yasinta; Sri Budiastuti; Retno Rosariastuti

Irrigation with textile wastewater and fertilization with an inorganic fertilizer containing lead (Pb) have negative impacts for agricultural sectors, especially lead contamination in a rice field and its uptake by rice plant. The rice grain that contains Pb is dangerous if consumed by humans, so it needs treatment to suppress Pb uptake by rice. Agrobacterium sp. I30 and vermicompost have a role as chelating heavy metals agents. The purpose of this study was to determine the effect of the chelating agents to suppress Pb uptake by rice in Kebakkramat, Karanganyar of Central Java. The method used was the quantitative method through a completely randomized block design with two factors (inorganic fertilizer and chelating agents). The results showed that application of Agrobacterium sp. I30 without inorganic fertilizer decreased Pb content in rice from 5.03 mg/kg to 4.97 mg/kg with a decrease in Pb uptake of 6.28%. Application of vermicompost without inorganic fertilizers decreased Pb content in the rice from 5.03 mg/kg to 1.61 mg/kg, with a decrease in Pb uptake of 72.18%. The use of both chelating agents can be recommended to suppress Pb uptake by rice in polluted soil and increases the safety of rice for consumption.

Mungbean (Vigna radiata L.) productivity in dryland decreased recently due to the soil fertility degradation. The objective of this study was to evaluate the effect of biochar types and cattle manure rates on the growth of mungbean in semi-arid dark soil. The factorial completely randomized block design 3 x 5 with four replicates was set to arrange treatments for the field trial. Two biochars (rice husk and sawdust) at 10 t/ha in combination with four rates of cattle manure (1, 3, 5 and 10 t/ha) and control (without biochar and cattle manure) were applied to the soil, incubated for three weeks and then planted with mungbean cv. Fore Belu. The results revealed that additions of biochar and cattle manure increased soil moisture and soil electrical conductivity by 2-4% and 0.15-0.20, respectively; decreased soil temperature and bulk density by 1-2oC and 0.2 g/cm3, respectively; increased plant height, stem diameter, root length, total, shoot and root dry weights by 4 cm, 0.1 cm, 5 cm, 7 g, 0.9 g and 6 g, respectively, compared to the control. The best growth of mungbean was obtained from the additions of sawdust biochar at 10 t/ha and cattle manure at 3 t/ha.

The demand for shallots is getting higher as the population grows. Indonesia targets to become a self-sufficient country of onion and the largest exporter of shallots in ASEAN by 2045. One of the shallot production centres is Losari District, Brebes, but the shallots productivity has decreased, so it is necessary to know the cause and the improvement effort to overcome it. The research was a land survey and evaluation to determine the current and the potential land suitability classes for the shallot. Data analysis using LMU (Land Map Unit) as the unit of analysis, which is the result of an overlay of soil type map, slope map and land use map using ArcGIS 10.3. The sampling method was purposive sampling and data analyzed using the matching method between the results of land characteristics data with the requirements of shallots growing. Results showed that even in production centres, the current suitability classes are marginally suitable (S3) as the heaviest limiting factors are very high rainfall. Improvement efforts to overcome this can be done by using suitable varieties, making gully drainage and using mulch/shade so that the potential land suitability class increases to be moderately suitable (S2).
