Abstract

Gold mining is an activity that utilizes natural resources by extracting the economic value of the deposits. Mining activities can produce hazardous pollutants, namely Hg (mercury), which can physically, biologically, or chemically damage soil quality. This study aimed to determine the role of biokanat application on the chemical properties of ex-mining land and to determine the effect of biokanat on reducing Hg levels in Kanagarian Padang Sibusuak, Sijunjung Regency. This study was a field experiment with 3 biokanat treatments (0, 10, and 20 ton/ha) with 3 replicates. The experimental 9 units were allocated based on Randomised Block Design. The data were statistically analyzed using an F-test with a 5% significance level. Then, it was continued using DNMRT if the Fcalculated > Ftable. The results showed that the dose of biokanat 20 ton/ha could increase the soil pH to 6.08, organic-C to 2.4%, P-available to 11.96 ppm, total-N to 0.23%, CEC to 2.58 cmol/kg, the basic cations especially Ca into 3.53 cmol/kg, Mg into 0.37 cmol/kg, K into 0.26 cmol/kg, and Na into 0.29 cmol/kg. Application of biokanat 20 ton/ha reduced the soil mercury (Hg) content to 15.96 ppm. Keywords: biocanat, mercury, gold mining

Abstract

Good oil palm cultivation contributes to the progress of the national economy by earning foreign exchange and income, creating jobs, and increasing welfare. However, independent palm oil farming has low productivity and quality due to limited knowledge and skills of GAP (Good Agriculture Practices). The research aims to formulate improvements in GAP skills, including technical skills, human skills, and conceptual skills, using skills theory and the concept of sustainability. The research method was descriptive-quantitative with Multidimensional Scaling using the Rap-Palm Oil program on 100 respondents in Sambas Regency, one of the centers of independent oil palm smallholders in West Kalimantan. The results showed that conceptual skills through extension activities are prioritized in improving GAP skills. Therefore, counseling methods through demonstration plots, comparative studies, and field schools can be an effort to improve GAP skills for sustainable management of oil palm farming. Keywords: good agriculture practices, multidimensional scaling, palm oil, skills

Abstract

This study aimed to determine the role of water hyacinth (Eichhornia crassipes Mart.) organic matter on water retention at pF 2.54 and pF 4.2, available water content, and bulk density (BD). The research method used was a factorial randomized block design. The first factor was the sorghum variety, which consisted of 2 levels, namely, V1 (variety) and V2 (Kawali). The second factor was the dose of water hyacinth organic matter, which consisted of 5 levels, namely P0 (without the application of water hyacinth organic matter), P1 (10 tons.ha-1), P2 (20 tons.ha-1), P3 (30 tons.ha-1), and P4 (40 tons.ha-1). Water retention was measured at pF 2.54 and pF 4.2 using a pressure plate apparatus and pressure membrane apparatus, respectively, and BD was measured using the ring method. The results showed that the treatment of organic matter application and varieties had a significant effect on water retention at pF 2.54, available water content, and BD with the best treatment of 40 tons of organic matter application and Kawali variety, but not affecting water retention at pF 4.2. There was no interaction between water hyacinth organic matter and sorghum varieties to improve water retention and BD. The highest water retention at pF 2.54 was 32.24% (P4), and the highest available water content was 11.67% (P4) but not significantly different from P3 (11.55%); the lowest BD was 1.11 g.cm-3 (P4) but not significantly different from P3 (1.13 g.cm-3). A very strong positive linear and negative linear correlation exists between available water content and BD with plant height, panicle length, and sorghum yield. Keywords: bulk density, water hyacinth, water content, water retention, sorghum

Abstract

The phenomenon of leveling off and environmental degradation that occurs as a negative impact of the excessive use of chemical fertilizers and pesticides encourages the development of organic farming systems that can produce crop yields that are not contaminated and free from synthetic chemicals and maintain a healthier environment. The research was conducted from October to December 2022 by taking soil samples from farmers' paddy fields in Tegal Regency using an organic (Cawitali Village) and conventional or non-organic (Jembayat Village) farming system. Composite soil samples were taken from a soil depth of 0 to 20 cm from the soil surface using a soil drill on lowland rice fields with organic farming systems and conventional farming after harvest. The analysis of the chemical properties of the soil carried out was C-organic (Walkley and Black), N-total (Kjeldahl), CEC and soil bases (exch-Ca, exch-Mg, exch-K, and exch-Na), total P (25% HCl) and available P (Bray I), while the observed soil biological properties were the total number of microbial and fungal populations. The results showed that organic paddy soil's chemical and biological properties were relatively higher than conventional paddy soil's. Total fungi in organic lowland soils were lower than in conventional paddy fields. The nutrient status of C-organic and N-total in organic rice fields tended to increase compared to conventional rice fields, namely from very low to low and low to moderate, respectively. In contrast, the other nutrient statuses observed tended to remain relatively unchanged. Generally, soil biological and chemical properties were better in organic farming than in conventional farming systems. Keywords: leveling off, organic farming, conventional farming, nutrient status

Abstract

This research analyzes consumer behavior and its impact on the purchase decisions of ornamental plants at Taman Anggrek Ragunan, South Jakarta. The Taman Anggrek Ragunan is the largest ornamental center in Jakarta. During the COVID-19 pandemic, demand for ornamental plants at Taman Anggrek Ragunan decreased by 50%. This research aims to determine the characteristics of ornamental plant consumers and analyze consumer behavior and its impact on purchase decisions of ornamental plants at Taman Anggrek Ragunan, South Jakarta. Respondents in this research were ornamental plant consumers who made purchases at Taman Anggrek Ragunan and were selected using a non-purposive sampling technique. The data used in this research comprises primary data and secondary data. For qualitative data, we convert it using a Likert scale to be analyzed quantitatively. The data analysis method uses multiple linear regressions. The results of the research show that the factors that have a significant impact on the decision to purchase ornamental plants at Taman Anggrek Ragunan, South Jakarta, are personal factors and psychological factors, while social factors and cultural factors do not have a significant impact. Personal and cultural factors have more influence on purchasing decisions for male respondents than female respondents. The four variables influence respondents with a high school education level more than undergraduates. Meanwhile, based on income level, the influence of the variable is stronger for respondents with an IDR 4 million or less income. Keywords: consumer behavior, multiple linear regression, ornamental plants, purchasing decisions

Abstract

Vegetable cultivation in tropical riparian wetland is currently suboptimal due to unpredictability of water dynamics. Chili pepper is a fruity vegetable that is often cultivated in tropical riparian wetland but is often constrained by conditions of excessive water saturation, such as shallow water tables, waterlogging and submergence in the transition period (dry to rainy season). The aim of this research was to study the morpho-agronomy of varieties of chili peppers under waterlogging stress during the early vegetative stage. A Plot Design was used in this experiment. The main plot consisted of (1) control (field capacity, regularly watering) and (2) waterlogging (simulated by adding water to the growing substrate until a thin layer of water was visible above the substrate surface during four days, followed by a seven-day recovery time during seven days). The subplot consisted of three chili pepper varieties, namely Laris, Romario, and Takanotsume (Japanese variety). Results of this study revealed that waterlogging stress significantly affected root length, number of leaves, total leaf area, chlorophyll content (SPAD), root fresh weight, shoot fresh weight, root dry weight, and shoot dry weight after stress and after recovery time. Meanwhile, chili pepper varieties were only significantly affected the total leaf area and chlorophyll content (SPAD). The total dry weight of Romario and Takanotsume before stress, after stress and after recovery did not significantly increase under waterlogging stress, whereas the total dry weight of Laris was precisely increased, indicating that vegetative growth is continuing. The Laris was categorized as one of chili pepper varieties that had medium tolerance to waterlogging stress at the early vegetative stage. Keywords: Capsicum annum L., soil plant analyses development, total dry weight, waterlogging

Abstract

Regional economic development is closely related to the role of the agricultural sector. In addition to food production, agriculture also contributes to the absorption of labor. During the COVID-19 pandemic, regional economic growth in Indonesia tended to decline, as well as in Padang Pariaman. Padang Pariaman will have a negative growth rate of 10.46% in 2020, the lowest compared to the average GDP growth rate of the other region in West Sumatra. This study aims to determine the dynamics and competitiveness of the agricultural sector compared to the other sectors. The research was conducted in a quantitative and descriptive manner using time series data for the period 2016–2020 from BPS. Data analysis using Klassen typology and shift share analysis. The results showed that the agricultural sector has an average share of 21.37% of the GDP of Padang Pariaman. Based on Klassen's typology analysis, the agriculture sector was included in the potential sector category in 2017–2019 but shifted to the developed sector category in 2020. Despite experiencing slow growth, the results of shift share analysis show that the agricultural sector in Padang Pariaman is still competitive. Increasing the competitiveness of the agricultural sector can be pursued by expanding sector linkages with the other economic sectors and increasing diversification of economics activities in agricultural sector Keywords: agricultural sector; shift share analysis; tipology klassen

Abstract

True shallot seed (TSS) is one of the alternative potential technologies to solve the availability of seed quality on shallot in Indonesia. Another problem in shallot production is infection by purple blotch and twisted disease. This research evaluated the potency of Rhizophagus intraradices and Trichoderma asperellum as bioprotectants and biofertilizer. T. asperellum was mixed in the soil before seedling transplanting, and R. intraradices was applied around the seedling roots at transplanting. The observed parameters were the shallot growth (the plant height, number of leaves, and length of root), plant health (disease incidence and intensity), and bulb resistance to Fusarium solani. The result showed that R. intraradices and T. asperellum increased the resistance of onion bulbs to the pathogen F. solani in the postharvest period, indicated by R. intraradices treatment that had an infection area of 21.99 mm2, followed by T. asperellum treatment 26.63 mm2, and control of 37.66 mm2. Keywords: Rhizophagus intraradices, Trichoderma asperellum, true shallot seed
