Abstract

Corn (Zea mays) is a cereal crop and has become a staple food. Purple corn has more excess compared to corn in general. In addition, purple corn has high nutrient content and anthocyanin levels. This study aims to determine genetic parameters such as variability, heritability, and genetic advance of the F2 generation resulting from an open-pollinated hybridization. The research was conducted from January 2020 to June 2020 on the Research and Experimental Field of the Department of Agrotechnology, Universitas Bangka Belitung. The work used a single plant design. The lines used were derived from the results of the previous selection stage. The results showed that the phenotype variability was relatively wide on the weight character of ear cobs with cornhusk, and the cob weight without cornhusk. High heritability values are found in the characters of harvest age, age of male flowering, and age of female flowering. The value of expected genetic advance for high expectations is found in the characters of plant height, the row number of seeds, the weight of 100-seeds, and the weight of cob with cornhusk. The selection results suggest nine corn lines that can be used for the next generation selection. Keywords: corn, expected genetic advance, heritability, purple, variability

Abstract

Spodoptera frugiperda was found to have entered Indonesia and damaged maize crops. There is a concern that climate change in Indonesia will cause these pests to migrate to other crops besides corn, such as kale and leeks. This research was conducted to observe the life cycle of S. frugiperda with feed treatment of kale leaves, leeks and corn leaves as a control. The larvae came from corn fields that were infested by S. frugiperda and were cultured in the laboratory. The variables observed were larva length, head diameter, pupa length, number of eggs, sex ratio, and time to complete one cycle. The life cycle of S. frugiperda varies between 37 and 47 days. Kale leaf feed is a good feed for the growth of S. frugiperda compared to the other two feeds, while corn leaf is good in fecundity. Keywords: corn, fecundity, growth, life cycle, sex ratio

Abstract

This study aimed to determine phosphate fertilizer and mycorrhiza dosages as well as the interaction of both treatments to the physiological character and the yield of ciplukan plants. The experiment was carried out from February to July 2020 on an experimental farm. The study used a Randomized Completely Block Design, consisted of two factors. The first factor was the dose of SP-36 fertilizer, containing 36% phosphate (P2O5), and the levels were P0 = 0% dose (0 kg/ha), P1 = 25% dose (75 kg/ha), P2 = 50% dose (150 kg/ha), and P3 = 100% dose (300 kg/ha). The second factor was the mycorrhizal dose, namely M0 = 0 g, M1 = 3 g, M2 = 6 g, and M3 = 9 g (containing 10 spores per 3 g). Each treatment combination was in triplicates. The measurement and observation data were analyzed using the analysis of variance (F-test), followed by Duncan's multiple range test with P-value = 0.05 and regression. The results showed that application of 75 kg/ha dose was equivalent to the application of 300 kg/ha. P uptakes at 75 kg/ha and 300 kg/ha dose of fertilizer were 22,03 ppm and 23,18 ppm, respectively. The plant growth rate was 12,39 g/cm2/week on the application of 75 kg/ha fertilizer and resulted in 14,24 g/cm2/week on 300 kg/ha dose. The mycorrhiza application was significantly different from the root infection at a dose of 6 g, namely 49.177%. There was an interaction between the dose of SP-36 fertilizer and the mycorrhiza on leaf chlorophyll content at a dose of 0% and 3 g mycorrhiza. Keywords: Physalis angulata, mychorrhiza, phospate fertilizer, physiological character and yield

Abstract

The intercropping method is one way to maximize plants and soil's utilization in a dry land. This study aimed to determine the cultivation (cropping methods and fertilization) that could increase mungbean grain yield in dry land in the dry climate of East Sumba, East Nusa Tenggara Province. The experiment was conducted at dry land in a dry climate in Laipori Village, Pandawai District, East Sumba Regency in 2017. The experiment was laid out in a split-plot design with four replications. The main plot was a cropping pattern, namely (1) intercropping mungbean with maize. Mungbean plant spacing was 30 cm ´ 20 cm, two plants per hole, and maize plant spacing was (50 cm ´ 50 cm) ´ 120 cm, one plant/hole and (2) mungbean monoculture with a plant spacing of 40 cm ´ 10 cm, two plants/hole. The subplot was dosage and type of fertilizer, namely (1) 150 kg Phonska/ha, (2) 5000 kg cow manure/ha, and (3) 75 kg Phonska + 2500 kg cow manure/ha. The mungbean variety used was Vima 1, and the maize variety was Bima. The results showed that intercropping mungbean with maize could increase the yield of mungbean seeds yield by 0,28 t/ha (51,85%) and increase the mungbean biomass by 0,31 t/ha (22,30%) compared to the monoculture system. Different types and dosages of Phonska inorganic fertilizer and cow manure did not cause differences in the mungbean yield.

Abstract

This study aims to analyze the impact of the tariff and non-tariff policies implementation of the importing countries on the export performance of Indonesian processed tuna. A cross-sectional gravity model analysis was conducted to find out the impact of these policies on exports. The variables used include GDP per capita of the importing countries, population, economic distance, export prices, actual exchange rates, tariff policies, and non-tariff policies in the form of sanitary and phytosanitary (SPS) and technical barriers to trade (TBT). The estimation shows that the variables of GDP per capita of the importing countries, population, exchange rates, export prices, and SPS give a positive and significant effect on the trade of Indonesian processed tuna commodities. On the other hand, economic distance and TBT policy give a negative and significant impact on the volume of this particular commodity. Meanwhile, the tariff policy implementation also give a negative effect on the export volume, but it is not significant. Keywords: cross sectional gravity, export performance, non-tariffs, tariffs

Abstract

Primary energy demand in Indonesia has rapidly increased, i.e., 43.33% between 2005 and 2016, while domestic energy supply failed to fulfill these needs leading to the reliance on the energy import. Meanwhile, a vast area of degraded land in Indonesia also created an opportunity for biofuel production, fulfilling energy demand, as well as restoring the land with environmental and socio-economic benefits. This paper provides an overview of identified potential and challenges associated with biofuel production from degraded land in Indonesia. Our preliminary findings highlighted that some biofuel species in Indonesia are suitable to grow in degraded land and potentially restore the land that may not be suitable for current agricultural production and/or reforestation. The initial finding also shows that culturally familiar species and stable markets are favorable terms of biofuel-species selection for the landowners. Supportive agricultural-extension services such as knowledge and technology for honey production can provide an added value in this concept, in addition to social (e.g., strengthening social solidarity and employment opportunities) and environmental (e.g., carbon storage, soil moisture, erosion control, and biodiversity) benefits. Meanwhile, to create this overall initiative to be successful, a supportive measure from the policymakers is needed. Further research on the capacity of biofuel species to restore degraded lands in different biophysical profiles. Analysis of biofuel production feedstocks and potential co-benefits viable business models, and the stable market is necessary to maximize benefit from biofuel production and to restore the degraded lands in Indonesia. Keywords: biofuel production, renewable energy, restoring
