Abstract

Coal mining is an activity to exploit land to get coal stored underground. Environmental problems in coal mining activities are generally associated with Acid Mine Drainage (AMD). The purpose of this study was to find out the best combination of organic matter and incubation time in remediating acid mine drainage on wetlands with water hyacinth plants. This research was conducted at PT Berau Coal in Tanjung Redeb, Berau, East Kalimantan. This study used a split-plot design. The main plot was the treatment of a combination of organic matter which consisted of 4 levels: A0 as a control (without organic matter), A1 with a combination of compost + sawdust (1:2), A2 with a combination of compost + sawdust (1:1), A3 with a combination of compost + sawdust (2:1). The subplot was treatment incubation time consisting of 2 levels, namely for 15 days and 33 days. Data analysis used variance analysis at the 5% level followed by the Duncan Multiple Range Test with a level of 5% when there were significant differences. The results showed that the addition of organic matter had a significant effect on the increase in pH and a decrease in the concentration of Mn in water, but it did not significantly affect the decrease in Fe concentration in water. The best combination of organic matter in acid mine remediation in this study was compost + sawdust (2:1) during the incubation time of 33 days

Abstract

Biofertilizer production in Indonesia should fulfil the minimum requirement for being produced and released to the market. Problems occurred when those products are being absent on informing those expiration dates and the viability of microbial activity which then closely related to the quality of the product. Seaweed composted material are potential resources for producing Biofertilizer, but lacking on the optimization on their process as this material contain a various important component for soil and environment. The production of Biofertilizer from seaweed waste required an optimum condition, i.e.: pH and typical microbe which could germinate under specific formulation and temperature. This study aimed to determine the optimum pH in liquid fertilizer formulations made from seaweed waste in the form of composted material, to test the viability of three bacterial isolates and those pathogenicity properties, to examine the effect of metabolites release from bacterial isolates to green bean seed germination. The experimental design used was a completely randomized design with four treatments, which were as follow: P0 as a control (Peptone), RP1 (seaweed waste), RP2 (seaweed waste and glycerol), and RP3 (seaweed waste and PEG). The three bacterial isolates used were: (1) Bacillus licheniformis, (2) Psudomonas plecoglossicida and (3) Pantoea ananatis. This liquid fertilizer biological formulation was stored for 8 weeks at pH 5.5 and temperature 25oC. The results showed that the treatment of RP1 (seaweed waste) had high bacterial viability and could stimulate growth for green bean sprouts. The carrier material for seaweed waste with the addition of glycerol and PEG showed no effect of the disease and symptoms of a pathogenic bacterial consortium on germination of green beans.

Abstract

Maize is one of the food crop commodities that can take a role in the development of the agricultural sector. The purpose of this research was to know the effect of pyraclostrobin and nitrogen on the maize plant. The experimental design used in this study was a factorial completely randomized block design with three replications. The first factor was pyraclostrobin (P) that consisted of P0 = no pyraclostrobin application, and P1 = foliar spray of pryraclostrobin 400 mL/ha. The second factor was nitrogen application (N) that consisted of N0 = without N fertilizer, N30 = 30 kg N/ha, N60 = 60 kg N/ha, N90 = 90 kg N/ha, and N120 = 120 kg N/ha. The data was focused on the plant height, flowering and earing age, protein and amylose content of the seed, respectively. Data were analyzed by variance analysis followed by. analysis of the least significant difference (LSD) at the level of 5%. Nitrogen application increased protein content but reduced amylose content. Pyraclostrobin application that significantly increased the amylose content even in the high nitrogen application dosage

Abstract

DEM is a digital model that provides topographic information. DEM can be made from terrestrial surveys, aerial photography, video, optical, and radar satellites, LIDAR and multidata combination. In general, DEM can be in the form of DSM and DTM. This study aims to explain the classification of DEM based on terrestrial and non-terrestrial, the methods of DEM extraction, vertical accuracy, data formats, and technological trends. The methods of DEM extraction discussed include stereo, interferometry, DEM combination, videogrammetry, and terrestrial data interpolation. In addition, a comparison of vertical accuracy is also carried out with several methods of its extraction. DEM can be used for various applications involving land surface, especially for 3D modeling, spatial planning, geology, topography, and so on. This DEM is used to support the activities of inland waters on Rote islands.

Abstract

In addition to tree planting activities, finding an alternative method to restore degraded land in semi-arid areas is necessary, and direct seeding of woody plants might be an alternative option. The objectives of this study paper were (1) evaluate the growth, biomass and survival of different woody plant species established through direct seeding in a semi-arid degraded land; (2) identify woody plant species that could be further used for restoration of degraded lands. To achieve the objectives eight woody plant species seeds were gathered, their seeds were sown in a degraded land, in a randomized complete block design (RCBD) (n=4). Data on germination, growth and survival of the different woody plants were collected at regular intervals during an eleven-month period. At the end of the study period, the remaining woody plants' dry biomasses were assessed. One-way analysis of variance (ANOVA) was used for the data analysis and mean separation was performed using Fisher’s least significant difference (LSD) test (p=0.05). The result revealed significant differences on the mean heights, root length, root collar diameters, root to shoot ratio, dry root biomasses and dry shoot biomasses of the different species (p < 0.05). There were also variations among species in their germination, dry biomasses and survival. The survival of the woody plants was inversely correlated with air temperature. Of the species studied, four tree species, Dodonaea angustifolia, Vachellia tortilis, Vachellia seyal and Vachellia nilotica, were successful in growing in the degraded land; and therefore, we recommend these for restoration projects

Abstract

Rangsang Island is home to more than 48,000 residents. Climate change has been a critical issue to the Island and threatened the existence of the inhabitants. This study is proposed to identify the zone of the coastal area of Rangsang Island which is vulnerable to climate change. By mapping coastal vulnerability index (CVI) of the island, it is expected to be a reference of local government in planning their spatial management. The method of this study was by a direct survey for collecting data of geomorphology, beach elevation, sea level rise, tidal fluctuation, significant wave height, and changes in the coastline. To determine CVI, each parameter is divided into 5 categories and given a value level: 1 for very not vulnerable, 2 for not vulnerable, 3 for moderate, 4 for vulnerable, and 5 for very vulnerable. The results show that most villages on the island are classified as highly vulnerable to climate change, namely 9 villages. Even 2 villages are threatened very high risk because the village has CVI more than 12.5. Only 6 villages whose territory has moderate vulnerability index. Vulnerability level of coastal Rangsang Island is strongly influenced by geomorphological variable and coastal elevation. In addition, the variable coastline changes and sea level rise also contributed to the vulnerability index of the Island.

Abstract

Combining the application of organic manure with inorganic fertilizer treatment can improve the productivity of the cucumber. Biogas slurry is synthesized from organic manure that can improve soil fertility and increase the yield of cucumber. This research aimed to learn the effect of biogas slurry and inorganic fertilizer on soil fertility and its impact on yield of cucumber and to learn the role of biogas slurry in decreasing amount of inorganic fertilizer used on the crop. This research was conducted in former paddy field located in Wriginsongo village, District of Tumpang, Malang Regency from March to May 2017. A randomized block design factorial was used with biogas slurry treatment as the main plot which consists of three levels: 10 t ha-1, 20 t ha-1, and 30 t ha-1while the subplot was the dosages of inorganic fertilizer which consists of100%,75%and 50% dosage of recommendation. This research revealed that biogas slurry treatment could increase the organic matter on the plant. There were some interactions between biogas slurry and inorganic fertilizer in the number of fruits produced, the weight of the fruit, the total weight of fruit produced per plant and hectare. Biogas slurry improved organic matter from 0.29% to 2.06%, N total from 0.06% to 0.15%, P2O5 from 93.48 ppm to 224.31 ppm, K2O from 2.01me 100 g-1 to 100 me 100 g-1, and C/N ratio from 3 to 9.

Abstract

Composting is an alternative way to accelerate decomposition and maturation of residual waste from refining leaves of cajuput to be suitably applied to the soil. The application of Cajuput Waste Compost (CW Compost) is intended to increase the productivity of sandy soil in Indonesian dryland. Compost serves as a soil conditioner that can improve the physical, chemical and biological properties. The study aimed to determine and analyze the role of CW compost in improving the physical quality of sandy soil in two incubation periods. The study used experimental methods, through soil incubation that given CW compost, in a greenhouse with two incubation periods. The experiments used a completely randomized design with 4 levels of CW compost treatment, namely: 0 t/ha (P0), 10 t/ha (P1), 20 t/ha (P2), 30 t/ha (P3). The results showed CW compost had a significant role in improving the physical quality of sandy soil both at 1-month and 4-month incubations. The soil physical quality increased by increasing compost levels and incubation periods, except for the total available water variable which decreased after 4-month incubation. The decrease was allegedly due to the reduction of labile fraction in the soil

Abstract

Tomatoes are a horticultural commodity and the main priority to be developed in Indonesia. To improve the production of tomatoes, land expansion is needed. Managing marginal land to grow tomatoes can be an option. Marginal land such as saline land has the potential to be developed as an alternative. This research is aimed to investigate the effect of K fertilizer on the growth and yield of tomato plants at different levels of salinity. The experiment was conducted in a greenhouse located in the rural area of Bendosari in Kediri, East Java, using factorial randomized block design. The first factor was NaCl concentration (0, 3000, 6000 and 9000 ppm) while the second factor was the dosage of ZK fertilizer (75, 150 and 225 kg/ha). The results Showed that salinity level reduced growth and yield of tomato while the dosage of ZK fertilizer did not affect. Salinity level on 3000 ppm reduced leaf area 20.35 %, shoot dry weight 27.18%, root dry weight 28 %, number of fruit 24.14 %, fruit weight per fruit 29.82 % and fruit weight per plant 12.42 %. However, salinity level on 6000 and 9000 ppm ware not significantly different at all variables except 6000 ppm in leaf area (reduced 37.06%) and 9000 ppm on the number of fruit (reduced 43.01%).
