Precision Agriculture Using Internet Of Thingsin Regosol Soil

Abstract The utilization of information and communication technology, especially the Internet of Things (IoT) can use sensors (along with the application interface). Sensors are able to measure features in the soil at any time such as pH, humidity and nutrients. Measurements can be made at any time, meaning the sensor is also able to monitor changes in the value of these features. This study aims to implement an Internet of Things (IoT) Information System to measure and monitor humidity, pH, and NPK levels in Regosol soil planted with mustard greens with capillary irrigation and liquid organic fertilizer. This study used a completely randomized design with two factors, namely the type of liquid organic fertilizer and the number of capillary irrigation wicks. The first factor consists of 4 levels: P0: No liquid organic fertilizer, P1: 5 liters/ha Liquid organic fertilizer from household waste, P2: 5 liters/ha Liquid organic fertilizer from Biduri leaves, P3 : 300 kg/ha NPK fertilizer. The second factor consists of 3 levels: I0: No capillary irrigation, I1: Capillary irrigation with 1 wick, I2: Capillary irrigation with 2 wicks. The results showed that the soil moisture during the growth of mustard greens was 16.59% to 23.48%, the more capillary wick, the higher the soil moisture, the average water requirement for mustard plant growth was 3.16 liters. The application of liquid organic fertilizer has a significant effect on soil pH and soil NPK levels. Capillary irrigation had a significant effect on soil pH, but had no significant effect on soil NPK levels.

The Effect of Dolomite Liming on Ex-Waste Disposal as a Media for Growing Green Mustard

Temporary waste collection (TPS) is not carried out with proper management, causing environmental damage. Piles of garbage collected at TPS come from disposal of domestic waste. To handle waste, waste handling procedures must be carried out, namely 3P (collection, transportation and disposal). If handling is not carried out, the land where the TPS is located will experience damage to the ecosystem. According to PP. 18/2008 states that waste management mandates that for each type of waste management efforts are made to limit and reduce it, except for disasters. Soil from piles of garbage changes its natural environment. Chemical elements resulting from the decomposition of waste due to being buried for years produce leachate (waste water). Wastewater damages microorganisms in the soil, especially from inorganic waste. Soil chemical properties are determined by the pH level or what is known as soil acidity (pH <7). Soil acidity can be increased by liming the soil. Limestone can increase calcium in the soil so that it can restore soil fertility and normalize soil pH. Dolomite is one of the agricultural limestone which has material from mountain limestone and shells. Dolomite lime is used to increase the pH of acidic soils or soil pH <7. The purpose of this study was to determine the stability of the former TPS with liming and its effect on mustard plants as phytoremediation. The results of observation and testing of used TPS liming treatment by applying variations of soil waste, dolomite lime, and husk charcoal. The treatments were divided into groups P0 (control), P1, P2, P3 (sand without dolomite). The results showed that the soil pH ratio of 1: 2: 1 (P2) reached a stability of 6.8 compared to other treatments. Meanwhile, from observations of green mustard plants, the highest average number of leaves was 16 on the 21st day, while the stem height was about 5.6 cm (P2). The average root length measured on the 21st day was 12.5 cm (P2). The conclusion is that the higher the dolomite mixing ratio, the soil acidity quality of the waste becomes stable, but the effect on mustard plant growth is not optimal.

PENGGUNAAN COAL FLY ASH (CFA) DAN TANDAN KOSONG KELAPA SAWIT (TKKS) UNTUK PERBAIKAN TANAH ULTISOL DAN SERAPAN LOGAM BERAT

Ultisol is the main type of land in Kalimantan, Sumatra, Papua and Sulawesi, with an area of almost 45.8 million ha or 25% of the land area of Indonesia. Ultisol has a relatively high acidity (average pH 4.5), high Al saturation, reaching 60%. The efforts to increase the fertility of ultisol soils such as the addition of organic materials such as Empty Oil Palm Bunches (OPEFB) and CFA (Coal Fly Ash) or Coal Fly Ash (CFA) improve the physical properties of Ultisol soil. Use of CFA that exceeds the limit can cause pollution especially copper (Cu) and lead (Pb). One way to recover soil from heavy metal contaminants with Phytoremediation technology, mustard (Brassica juncea L.) is one of the plants that easily absorb heavy metals so that it can be used as a Phytoremediation agent. The aims of this research to determine the use of CFA and OPEFB to fix up the ultisol soil and heavy metal content absorbed by plants. This study used Completely Randomized Design with 3 replications. The results showed that using of CFA and OPEFB can increase the available P so that it can increase the growth of mustard plants and absorption of heavy metals. By using the dozes of 54.54g CFA and 18.18g OPEFB (C3K1) can increase P- available at 181.67 m kg-1 . The uptake of heavy metals Cu and Pb in mustard plants is very high. The highest uptake in Cu reached 192.03 mg kg-1 , whereas in Pb it was 80 mg kg-1 . This number is still very high, so it is dangerous if consumed.

Hybridization of nitrogen compounds and hydroxyapatite: a slowly released fertiliser for water sustainability

Ammonium sulfate (ZA) and nitrogen-phosphorus-potassium compound (NPK) are nitrogen-rich fertilisers commonly used by farmers. The fertilisers have high solubility in water, decay rapidly in wet soil and decompose into ammonia. Its lead into eutrophication phenomena and its absorption by crop roots becomes less effective. A facile and scalable method is developed to adsorb nitrogen-rich compounds into fish scale based powdered hydroxyapatite for slow-release fertiliser (SRF). Hydroxyapatite (HA) is a material that contains phosphorus and is a well-binding agent of nitrogen. This study is aiming at synthesizing HA from calcium-rich fish scale biowaste using wet-chemical precipitation method and coated the HA particles with ZA and NPK fertiliser. The fertiliser in solid form were combine with HA particles with the ratio of 6:1, and dissolved in aquadest. Total nitrogen content were measured periodically by using percolation method. The nitrogen release of the hybrids was compared to obtain the best kinetics model and it was found that zero order kinetics model was suitable for ZA-HA sample and Kosmeyer-Peppas model was suitable for NPK-HA sample. Vegetative growth of mustard plants were used to measure the effectiveness of SRF, and were found that combination of NPK-HA and ZA-HA were able to enhance up to 17% of the plant growth compare with conventional fertiliser.
