Abstract

Indonesia is currently one of the largest coffee producers in the world, and involved in exporting coffee countries. The financial series data such export value of coffee is highly volatile in both mean and variance. Thereby, the model of ARIMA with order p,d,q is one way to deal with this error. The aim of this study is to determine the best-fitted ARIMA(p,d,q) model to forecast the monthly series of export of coffee from January 2005 to April 2020. The findings suggest that ARIMA(1,3,1) is the best-selected model due to its very significant p-value (less than 0.0001), which showed that the model is applicable for forecasting.  The model is then used to establish the prediction of ExCof monthly data for the next 12 months.

Abstract

This study aims to analyze the effects of the use of organic fertilizers and organic pesticides on eggplant productivity and the level of erosion hazards that occur on these intensive agricultural lands. The use of organic fertilizers and pesticides is expected to improve soil quality which in turn will increase crop productivity and reduce erosion yield. Randomized block design (RBD) was used with a combination of dosage treatment of organic fertilizers (P) and organic pesticides (B). The dosages of organic fertilizers used were: 0 kg/bed (P1/control), 1 kg/bed (P2), 1.5 kg/bed (P3) and 2 kg/bed (P4). The doses of pesticides used were chemical pesticides 2 ml/liter (B1/control), organic pesticides 7 ml/liter (B2), 9 ml/liter (B3) and 11 ml/liter (B4). The highest productivity research results were obtained from combination of P4B1 (fertilizer dose 2kg/bed + chemical pesticides). This shows that organic fertilizers and pesticides can increase plant productivity. However, organic pesticides have not been able to reduce pest attacks during the fertilization phase. On the other hand, the rate of erosion has actually increased which is not significantly different between the use of organic fertilizers and chemical fertilizers. This is due to the increase in the content of organic matter and changes in soil texture which cause the soil to become loose and crumb so that it is more easily eroded. Thus the use of organic fertilizers and pesticides can be used continuously in intensive agriculture but must be accompanied by other conservation activities to reduce the erosion yield. In addition, it is necessary to develop more effective organic pesticides to eradicate pests and plant diseases. Keywords: erosion, eggplant plants, intensive agriculture, organic fertilizer, organic pesticide.

Abstract

Farm cultivation in the highlands is constrained by the long rainy season, less efficient sunlight and susceptible to pests and diseases. One of the solutions in cayenne pepper cultivation is using hydroponics and greenhouse s to minimize pests and diseases that come from the soil and are carried by the wind. The purpose of this research is to produce "SMART-IGHIOT" a control system based on the Internet of Things using Dutch bucket hydroponics in a portable greenhouse. The technology applied is in the form of monitoring and controlling temperature, humidity, air temperature and light intensity using sensors integrated with the ESP32 microcontroller. The ESP32 is connected to the Thingspeak webserver to display sensor measurement results in real-time. The design of the monitoring system for light intensity, temperature and humidity in the greenhouse can be maximized so that environmental conditions can be optimized. The performance of using greenhouse s can maximize the intensity of sunlight, the highest at 12.00, while the lowest temperature at 03.00 to 05.00 WIB. While the highest temperature is at 13.00 and the highest humidity is at night. Keywords: dutch bucket, greenhouse, IoT, microclimate, Thingspeak

Abstract

The purpose of this study was to observe the effect of extreme rainfall patterns in the DI Yogyakarta region on the growths of rawit/cayenne (Capsicum frutescens L.) and keriting/curly (Capsicum annum) chili peppers. The experimental design used was Randomized Complete Block Design (RCBD) with single factor consisting of three levels namely: maximum frequency index (P1), rainfall intensity index (P2), and control treatment (K).  The frequency and intensity indexes (P1 and P2) of May-June-July from each weather station were used as the bases of rainfall simulations applied in watering the rawit and keriting chili pepper cultivations. Whilst, control (K) was the watering on the basis of optimum crop water requirement. The growth parameters observed included plant height, number of leaves, age of flowering, age of fruiting, age of first harvest, final weight of biomass, and yield. The data sets were analyzed by using one-way Analysis of Variance (ANOVA) at α=0.05 for each species. The results showed that the three levels of treatments did not significantly affect the growth and yield based on all parameters observed for both of the two species. So even the potted media were flooded, the water easily drained through the holed base of pots, making plant growth undisturbed. This finding suggested that planting chili peppers in pots or elevated media could mitigate the effect of extreme rainfalls.Keywords: Extreme Precipitation, Extreme Indices, Plant Growth, chili pepper

Abstract

This research aimed to determine the effect of biofertilizer application and alkali supplement fertilizer on the growth and yield of chili (Capsicum annuum L.) This research is arranged in a randomized block design (RBD) consisting of two factors and three replications. The first factor is biofertilizer with three levels, i.e., H0=without biofertilizer; H1= dose of 4 ml/plant; H2= dose of 8 ml/plant. The second factor is alkali supplement fertilizer with three levels, i.e., P0=without alkali supplement fertilizers; P1= dose of 0,05 gr/plant; P2= dose of 0,1 gr/plant. The results showed that the growth variable did not have a significant interaction effect between biofertilizer and alkali supplement fertilizer. Meanwhile, in production variables, there are interaction effects between the application of biofertilizers and alkali supplement fertilizer in variables of number of flowers, number of fruit consumption, and fruit weight per plant. The biofertilizer application with a dose of 8 ml/plant accompanied by alkali supplement fertilizers dose of 0,1 gr/plant resulted in the highest fruit weight, 436.70 grams/plant. The biofertilizer application of 8 ml/plant produced 402.12 grams/plant3, while the application of alkali supplement fertilizer with a dose of 0,1 gr/plant produces chili production of 400.51 grams/plant.Keywords: alkali supplement fertilizer, biofertilizer, chili

Abstract

This study aimed to examine the effect of Moringa leaf flour concentration on the physical and chemical properties and level of preference of Moringa corn bread. The study was conducted with variations of Moringa leaf flour concentration (TK): TK1 = 1%; TK2 = 3%; TK3 = 5%; TK4 = 7%. Parameters to be analyzed included physical properties, namely bread volume, specific volume of bread and bread elasticity. Chemical properties included water content, protein, vitamin C, β-karoten. The results showed that the highest macro- and micronutrient values in the addition of 7% Moringa leaf flour was inversely proportional to the physical properties of the bread, namely a decrease in the specific volume and elasticity of Moringa cornbread which resulted in a decrease in panelists' acceptance of Moringa cornbread products. TK3 was the best with protein value of 7.27 mg/100g, vitamin C 60.0 mg/100g, β-karoten 13909.99 µg/100g, specific volume of bread 3.71 cm3/g and bread elasticity. 75.14% and the highest sensory acceptance of moringa cornbread. Keyword: Physical, Chemical, Bread, Corn, Moringa

Abstract

This study aims to determine the performance of drip irrigation technology as compared to conventional farmer’s practice on rice growth and yield, grain quality, and water consumption. The research was carried out at the Sukamandi Experimental Station, Subang, West Java in July - October 2019. The test was arranged by a nested randomized block design with 5 replications. The main plot was water management with 2 levels: (1) Drip Irrigation Technology (DIT) and (2) Conventional Farmer’s Practice (CFP) (flooded condition) as a comparation. Subplot was varieties with 4 levels: two hybrid rice (1) Hipa 8 and (2) Hipa 18, upland rice (3) Inpago 11, and irrigated inbred rice (4) Inpari 42. The result showed that yield of DIT not significantly different to CFP with higher number of tillers per m2. However, it was lower for plant height, tillering ability, grain filling, 1000 grains weight, transpiration rate, assimilation rate and stomatal conductance. For grain quality determination, DIT gave an increase in the average of grain density and impurities, but decreased in the average percentage of chalky and immature grains. In Hipa 18, DIT was able to produce a higher percentage of head rice. DIT only consumed 3864 m3/ha/season water irrigation compared with average water consumption in Sukamandi Field Station which range of 7460-8740 m3/ha/season.Keywords: Drip irrigation, Rice, Water, Yield, Grain quality

Abstract

Solid waste has always been a problem for developing countries. In Bandar Lampung, the traditional market is the second largest contributor of solid waste, after households. Data for Traditional Market Solid Waste (TMSW) composition and generation rate in Bandar Lampung is rarely found, even though, data is needed to write the policy for TMSW management and its recycling potential. This research aims to provide data on TMSW composition, generation rate and chararacteristic in Bandar Lampung, also its recycling potential. The sample from 10 of 31 traditional markets in Bandar Lampung is collected for 8 consecutive days in morning and afternoon. Then, the sample was processed to obtain its composition, generation and density. 48.06% of TMSW compositions is donated by vegetable. Meanwhile, metal is rarely found in traditional markets, with only 0.37%. The average density of TMSW is 180.11 kg/m3, while Kangkung Market has the highest density with 237.84 kg/m3 and Cimeng Market has the lowest TMSW density with 123.07 kg/m3. The generation rate of TMSW is 53,602.35 kg/day. Biodegradable wastes from traditional markets in Bandar Lampung, with 53% water contents, can be potentially recycled by composting and/or anaerobic digester because of its economic value and characteristic. Keywords:   Recycling, Solid Waste Management, Traditional Market Solid Waste, Waste Characterization

Abstract

Chicken meat has a high nutrient content. However, its quality is easy to be degraded. The degradation is normally characterized by the formation of metabolite gases (NH3 and H2S) as deterioration indicators. Sensors detect phenomena better than human senses. This study aimed to classify meat quality based on gas formation during meat storage. In addition, a kinetics model of gas changes was determined. The gases were detected using a set of equipment consisting of Raspberry Pi and Metal-Oxide-Semiconductor (MOS) gas sensors. Samples were put in a 10 x 10 x 10 (cm) black container. MOS sensors were put inside the box to detect the gases at room temperature for 24 hours, with data collection being recorded every hour. Obtained data were then analyzed using Principle Component Analysis (PCA) for quality classification. The study showed that the quality of chicken meat was classified into three groups with a total variance of more than 95%. PC1 explained 88.2%, and PC2 explained 9.0%. The constant rate of H2S and NH3 changes followed the first-order kinetics with a constant rate of 0.2641 and 0.2925, respectively. The equation for H2S and NH3 changes were Ct=1.70 e0.2641 t and Ct=1.00 e0.2925 t, respectively. Keywords: Chicken meat, Freshness, H2S gas, NH3 gas, Sensor
