Abstract

The use of household waste in the form of rice washing water, pineapple skin waste, and leftover rice as liquid organic fertilizer (LOF) has the potential to create a good growing medium so as to increase plant growth. Brazilian Spinach (Alternanthera sissoo) is a leafy vegetable that has the potential to diversify vegetable consumption in urban areas where it is expected to grow well in tight spaces, particularly under shading. This study aimed to find out the effects of applying liquid organic fertilizer made of household waste and the shading on the growth of the Brazilian spinach plant. The study used a split plot design with a main plot consisted of 0%, 50% and 70% shading, while subplot consisted of LOF washing water (20 ml/l), pineapple peel waste (30 ml/l) and leftover rice (50ml/l). Each treatment was repeated 3 (three) times. The results of the study showed that the SPAD value of Brazilian spinach under shading treatment and LOF treatment of rice washing water linearly continued to increase until 8 (eight) weeks after planting. Regarding the vegetative growth of Brazilian spinach, the 0% shading treatment was the best treatment in terms of increasing the non-edible leaf fresh weight and root dry weight. Meanwhile, the LOF had an insignificant effect on all treatments. In conclusion, Brazilian spinach can grow more optimally in no-shade conditions.

Abstract

Research related to biodiversity that was carried out regularly could be part of monitoring activities to see changes in butterfly populations in an area. Butterflies have a role as environmental bioindicators that were commonly found in various places. Urban forests such as the Cibubur Arboretum and the University of Indonesia were mini conservation sites that were habitats for butterflies. The purpose of this study was to monitor changes in butterfly abundance in the urban forest of Cibubur Arboretum and UI. This research was conducted in 2014 and 2021. This observation was carried out by purposive sampling method. Each urban forest was divided into 3 different stations consisting of 2 plots (20 x 20 m), and repeated 3 times on each plot with an interval of 1 week using a sweeping net and camera. Observations were carried out for 1 hour on each plots. The total observations of butterflies in both urban forests were 18 times. Individual butterflies found in 2014 in the Urban Forest Arboretum Cibubur (339) individuals, and the year 2021 (232) individuals. in the UI City Forest in 2014 898 individuals were found and 269 individuals in 2021. Nymphalidae family was the family with the highest number of individuals found in 2014 and 2021. The individual species found in 2014, included in the category of sporadic, subrecedent, recedent, subdominant and dominant. Meanwhile, the butterfly species found at the study site were categorized into Sub-recedent, Recedent, and Sub-dominant groups in 2021. Differences in vegetation, changes in use, and anthropogenic disturbances could affect changes in butterfly observations.

Abstract

Every year, land use in Indonesia has increased, both for settlements, agriculture, and other uses that are used to meet the needs of human life for certain purposes. Cijengkol Village is one of the agricultural development villages in Subang Regency and is affected by topography, resulting in different types of land use. This mapping aimed to provide information related to the classification of land use for settlements, agriculture, plantations, fields, and others in Cijengkol Village. Land use mapping was carried out in this village to reveal the distribution of land use so that it could be taken into consideration, as well as directions for determining spatial planning by the local government. Therefore, this mapping was carried out by involving the Sentinel-2 MultiSpectral Instrument (MSI) image data source and processed using a cloud computing-based Google Earth Engine (GEE) platform. Six spectral scoring index algorithms exist the Enhanced Vegetation Index (EVI), Soil Adjusted Vegetation Index (SAVI), Specific Leaf Area Vegetation Index (SLAVI), Index-Based Built-Up Index (IBI), Normalized Difference Built-up Index (NDBI), and the Normalized Difference Water Index (NDWI). The results of the random forest (RF) classification algorithm resulted in six types of land use with percentages, namely mixed gardens (39.69%), agriculture (34.08%), homogeneous gardens (13.57%), residential (10.58%), open land (2.09%), and water bodies (0.001%). Image classification in this mapping also produces an accuracy rate of 82.43% (Overall Accuracy) and 0.78 (Kappa Statistics). The results of this research are of a good level of accuracy, so it is hoped that this research will become a database for the local village government and become a reference for further research.

Abstract

The yield was a complex quantitative character. It was due to many other characters being related to yield. This study aimed to determine the correlation between agronomic characters in maize and the characters that affect the yield of hybrid maize. This experiment was conducted at the Bajeng IP2TP, Indonesian Cereal Research Institute, Gowa, South Sulawesi from March to June 2022. The treatments consisted of ten hybrid maize genotypes. The treatments were arranged in a Randomized Complete Block Design (RCBD) with three replications. The variables observed were the agronomic component and yield component. Pearson's correlation was used to determine the relationship between characters, and the characters that affected the grain yield were determined by path analysis. The results showed the characters leaf length, leaf width, harvested plant number, harvested ear number, harvested ear weight, shelling percentage, ear length, ear diameter, kernel number per row and 1000 grains weight have a significant correlation to yield. Characters that affected to maize yields were harvested ear weight, shelling percentage and grain moisture.

Abstract

The aimed of this study was to determine the effect of chicken manure application on red chili plants using conventional and floating cultivation techniques. The research was carried out on the experimental farm for conventional cultivation techniques and in research pond for floating cultivation located in the Faculty of Agriculture, Sriwijaya University, Indralaya Campus, Ogan Ilir, South Sumatra with an altitude of 10 m above sea level from July to November 2022. The experiment used a randomized block design with one factor, namely chicken manure (0, 10, 20 and 30 tons/ha) with three replications. While the floating experiment used 200 cm x 100 cm of bamboo rafts. Parameters observed included plant height, number of leaves, crown diameter, fruit length, fruit diameter, fruit weight per fruit, and total fruit weight per plant. Data were analyzed using Analysis of Variance (ANOVA) at the 5% level. The results showed that increasing the dose of chicken manure up to 30 tons/ha in both cultivation techniques increased plant height and number of leaves. Likewise for the number and weight of fruit, obtained at the same dose in conventional techniques, namely 30 tons/ha. However, fruit length and diameter parameters were higher in floating cultivation at all doses of chicken manure treatments. Therefore, it was concluded that the use of chicken manure could increase the growth of chili plants in both cultivation techniques, although the size of the polybags used could not support the growth and yields optimally.

Abstract

Green eggplant was a vegetable which used for cooking ingredients and has rich nutrients. To increase the green eggplant productivity, it was necessary to improve the quality of growing media so the plant nutrition will be fulfilled. This study aimed to find out the best composition of growing media for the growth and yield of green eggplant. It used a Randomized Block Design (RBD) with 10 treatments for the composition of the growing media. The results of the analysis of diversity showed that the application of rice husk charcoal and chicken manure had a very significant effect on plant height, number of leaves, stem diameter, flowering age, harvest age, number of fruits per plant, fruit length, fruit diameter, and total fruit weight per plant. The results of the orthogonal contrast test showed that the green eggplant grown on soil media was very significantly different from the green eggplant grown on other growing media in all variables. The best results were obtained from the treatment of rice husk charcoal: chicken manure: soil (2:1:1) on the variables of plant height was 42.26 cm, flowering age was 22.33 days, total fruit weight per plant was 538.44 g, fruit diameter was 38.16 mm, and average weight per fruit was 81.66 g. The treatment of growing media composition using a combination of chicken manure and rice husk charcoal was better than the growing media with just one organic matter.

Abstract

The government launched a food diversification program, one of which was cassava so that the population does not depend on rice, and anticipates when rice production decreases due to crop failure. However, cassava production was much lower than rice. There were efforts to utilize suboptimal land to increase cassava suplly for population consumption. Therefore, this study aimed to assess the level of technical efficiency of cassava farming on suboptimal dry land. The research sample of 60 cassava farmers in Jaddih Village, Bangkalan Regency was taken by census to answer the research objectives. Stochastic frontier analysis was used to determine the effect of agricultural inputs consisting of land, seeds, labor, costs, and manure on the production of cassava. Then to determine the effect of age, experience, formal education, non-formal education, and family dependents on cassava insufficiency. The results show that cassava production will increase with the increase in land area, but will decrease with the increase in seedlings. The average technical efficiency of cassava was 87%, where this value will increase if farmers attend non-formal education. This research contributes to policy makers to optimize suboptimal land use, and to farmers to take advantage of production inputs and socio-economic variables that affect production increases and technical efficiency.

Abstract

The growick irrigation system is an underground irrigation that can prevent plant water loss because it directly wets the root area. The use of the width of the wick in the growick irrigation system is can meet the water needs of the growing media. The aimed of this study were to determine the effect of wick width using the growick irrigation system on the growth and yield of lettuce grown vertically. This research was conducted from April to May 2021. The research location was in the Experimental and Research Station, Faculty of Agriculture, Fisheries, and Biology, University of Bangka Belitung. The study was conducted using a randomized block design experimental method (RBD) which consisted of 5 levels of treatment. The treatment consisted of control, wick width 0.5, 1, 1.5, 2 cm.  The result shows that width of the wick of the growick and verticulture irrigation systems affected the crop water consumption but had no significant effect on the growth parameters and yield of lettuce. The treatment of 0,5 cm wick width tends to be better in supporting the growth and yield of lettuce in the vertical cultivation systems.

Abstract

The limitations of agricultural land currently encourage cultivation activities to be carried out with the use of limited space such as indoor cultivation by utilizing irradiation techniques and the use of varied planting media. This study aimed to evaluate the  growth and yield of  indoor-cultivated mustard microgreens to the irradiation duration and the composition of varied planting media. This study used a split plot design with the treatment of LED irradiation duration of 0, 10, and 20 hours/day, and the variations  of planting media, 100% soil, 100% compost, addition of 50% compost and cocopeat, and a combination of compost and cocopeat planting. The study results showed that the irradiation only affected the plant height in the both planting periods. The treatment of the composition of the planting media had significant effect on all variables observed in the two planting periods, while the interaction had a very significant effect on the plant height on 1st planting period and root length on 2nd planting period. The treatment of 50% soil + 50% compost on LED 10 hours/day had the highest yield of fresh weight in two planting periods. The use of 100% soil media inhibited the growth of mustard microgreens, while the irradiation of 0 hours/day in all planting media treatments showed the symptoms of etioliation. So, the treatment of 10 hours/day irradiation with the addition of 50% compost is able to provide  the best results in quality and quantity against the pH value and the growth and yield of mustard  microgreens.
