Abstract

Forest to oil palm plantations conversion has changed soil's physical properties significantly. It caused significant changes in the hydrological cycle and affects the water resources around the research site. One of the strategies that could minimize the negative impact of monoculture oil palm plantations is better plantation management by implementing a mixed cropping system (agroforestry). This study aims to analyze the infiltration, surface runoff, and surface runoff coefficient in agroforestry and monoculture oil palm. This observation was conducted in the oil palm plantation area of PT Humusindo Makmur Sejati, Bungku Village, Bajubang District, Batanghari Regency. The infiltration rate was calculated according to the Horton method, and the amount of runoff in agroforestry and oil palm monoculture used the soil conservation service-curve number method. The results showed differences in infiltration, surface runoff, and runoff coefficients between the agroforestry land and the monoculture oil palm. The highest infiltration is in A48, which is 42,00 cm/hour in the dry season and 18,00 cm/hour in the rainy season. The lowest runoff is in A23, which is 70.14 mm with a runoff coefficient of 0.04. The highest runoff occurred in S48 of 339.88 mm, with a runoff coefficient of 0.19. The differences in infiltration, surface runoff, and runoff coefficient in this study are affected by the vegetation density and the amount of litter. Keywords: agroforestry, infiltration, oil palm, runoff coefficients, surface runoff

Abstract

The agricultural sector is strategic and the third-largest contributor to the GRDP of West Java Province, but its growth has slowed during the 2016–2019 period. The slow growth rate can be caused by the determinants of the growth of the agricultural sector itself and is very likely to be affected by the spatial interaction between regions in the province. Therefore, this study aims to analyze the spatial effect between regions on the growth of the agricultural sector in West Java and identify the factors that influence the growth of the agricultural sector within the province by using spatial analysis of panel data. The results reveal that the appropriate model is a fixed effect spatial error model, which shows an effect of spatial interaction between regions on the growth of the agricultural sector in West Java Province. The factors that affect the growth of the agricultural sector are agricultural credit, agricultural road infrastructure, and diversification of economic activities. Keywords: agricultural sector growth, spatial autoregressive, spatial error model, spatial panel data

Abstract

Compacted feed such as wafers and pellets is still rarely given to cattle shipping in Indonesia because it requires an adaptation period to the newly introduced feed. This study aimed to observe forage compacted feed potency to minimize the adaptation period of kupang cattle to a new feed with high nutrient content. Two experiments were carried out to observe six feed formulations and four different feed forms. The first experiment was an experiment to determine three of six formulations with the same nutritional content to be tested in the second experiment. The second experiment was to observe four feed forms (wafers, pellets, dry pellets, and cubes) combined with the three best formulations from the first experiment. Six treatments and five replications using 30 cattle and 30 kg of feed were carried out in the first study, while the second one used a randomized factorial design of 4´3 treatments and 5 replications consisting of 60 cattle and 420 kg of feed. The results showed that there was no significant difference between the formulations at the same nutritional level. The highest consumption results were found in the form of wafer followed by cubes, pellets, and dry pellets (P <5%). The conclusion of this study is that the compacted feed in the form of wafers, pellets, and cubes can be used to eliminate the feed adaptation period. Keywords: feed logistics, compacted feed, kupang cattle, adapting period, feed adaptability

Abstract

The Archipelagic Fishing Port of Karangantu located in Banten Bay is one of the blue swimming crab fishing centers in the Java Sea. Covid-19 pandemic had significant effect on blue swimming crab fisheries in Karangantu, especially on the increasing of fishing operational cost, decreasing of price, and limited acces for market distribution. This study aims to analyse the feasibility of blue swimming crab fisheries activity using bottom gillnet in Banten Bay after Covid-19 pandemic. The research was conducted in May-June 2021 in Karangmulya Village, Kasemen District, Serang City with a total of 22 respondents. The data were collected using deep interview with each respondent who was selected purposively. The analysis of business feasibility was conducted based on the parameters of the ratio between income and costs (R/C), payback period (PP), and net present value (NPV). The results show the Covid-19 induced the decreasing of R/C ratio value from 2.08 before to 1.81 after Covid-19 pandemic, respectively. The value of PP also increased from 0.65 years to 0.68 years. Moreover, the potential profit of blue swimming crab fishing also decreased from IDR 55 million before Covid-19 to IDR 52 million after Covid-19 pandemic. However, due to the positive NPN value, the blue swimming crabs fishing actvity using bottom gill nets in Banten Bay is still feasible to be developed. Keywords: blue swimming crab, Covid-19, impact, fisheries

Abstract

Cassava is widely grown in Inceptisol. As agricultural land, the soil has several problems, i.e., high soil acidity, easily leached soil surface layers, unstable soil aggregates, and slow permeability. Arbuscular mycorrhizal fungi (AMF) form a symbiotic relationship with over 80% of higher plant species. However, the effectiveness of AMF on cassava has not been widely reported. This study aimed to determine the effect of AMF inoculants on the vegetative growth of cassava in Inceptisol. The AMF inoculants used were Gigaspora sp., Glomus manihotis, and a consortium of Acaulospora tuberculata and Glomus rubiforme. The experiment was performed in a Randomized Block Design with 8 treatments and 3 replications, i.e., M1 = G. manihotis; M2 = Gigaspora sp.; M3 = consortium of A. tuberculata-G. rubiforme; M4 consortium of G. manihotis-Gigaspora sp.; M5 consortium of G. manihotis-A. tuberculata-G. rubiforme; M6 consortium of A. tuberculata-G. rubiforme-Gigaspora sp.; and M7 consortium of G. manihotis-A. tuberculata-G. rubiforme-Gigaspora sp.; and control (as recommended dose of NPK fertilizers). In the AMF application treatment, 75% of the recommended NPK fertilizer was applied, thus saving 25% from the control. A total of 50 AMF spores were applied to each cassava plant and maintained for 8 weeks. The data were analyzed using the RStudio 4.1.1 program. The results showed that all treatments with AMF gave various effectiveness and could compete with the indigenous AMF. AMF application significantly increased the vegetative growth of cassava grown in Inceptisols, i.e., shoot and root dry weight, root length, P-uptake, and percentage of root infection. Application of G. manihotis and the consortium of A. tuberculata-G. rubiforme-Gigaspora sp. effectively increased cassava plants' growth for 8 weeks in Inceptisol. The AMF application could save 25% on the use of NPK fertilizers. Keywords: Acaulospora, cassava, Gigaspora, Glomus, fertilizer, mycorrhizal

Abstract

Coffee is one of the most important commodities traded widely in the world. To increase coffee productivity, maintenance efforts are needed such as maintenance, land clearing, fertilization, and cultivation. All of these steps require a large amount of money. For this reason, Chinese coffee farmers need loan funds to increase their productivity and income. This study aims to determine the results of the financing provided by BLU to coffee farmers in Cinanggela Village. Data collection includes primary and secondary data. Then, the study was carried out using the Microsoft Office Excel program and the Multi-Dimensional Scaling Method through the Rapid Appraisal for Fisheries (Rapfish) software. The results obtained indicate that there is a significant increase in the income of farmers, increased by Rp12,578,381 per ha with a production yield of 7496.9 kg per ha. This means that the maintenance of coffee trees in Cinanggela Village is included in profitable farming with an R/C ratio of 2.94. Meanwhile, the results of the sustainability analysis on the economic dimension show sufficient sustainability status with an index of 56.71. The ecological dimension shows a less sustainable status with a value of 49.93. And the social dimension shows the lowest sustainability status, namely 44.09 with the attribute value of coffee sales (2.4), community participation (3.2), and the frequency of conflicts between farmers (2.6). The low values of some of these attributes need to be used as inputs to the Environmental Fund Management Agency (BPDLH) as the successor to the financing previously carried out by BLU.

Abstract

The purpose of this study was to evaluate the effect of the treatment of organic material sources Mucuna and Crotolaria and the dose of vesicle arbuscular mycorrhizae (VAM) on the chemical quality of vertisol, nutrient uptake and maize yield in dry land. The research was carried out in the experimental field of the Kupang State Agricultural Polytechnic, in the village of Oesao, East Kupang District, Kupang Regency, East Nusa Tenggara. The study took place from May to September 2021. The study design used a factorial randomized block design. The first factortreatment was source of organic matter (B) of ground cover plant biomass, namely: B0 = no ground cover plant biomass; BM = Mucuna and its biomass are immersed; BC = Crotolaria and its biomass immersed. The second treatment was dose of VAM biofertilizer (D), namely: M0 = 0 g plant-1 (without VAM); M1 = 10 g plant-1; M2 = 20 g plant-1. The results showed that the application of organic material sources and the dose of VAM, respectively, could significantly improve the chemical properties of vertisol. The results showed that the use of organic matter and dose of VAM independently was proven to be the most effective in improving the chemical quality of vertisol. Application of organic matter Mucuna and Crotolaria at a dose of VAM 20 g plant-1 significantly increased N uptake in maize by 53.26‒54.45%, maize P uptake by 27.83% and 28.85%, and the yield of dry shelled corn by 146.92% and 146.92% compared to other treatments.

Abstract

The World Food Programme said that in 2020 there were 768 million people who experienced chronic hunger due to the increase in world poverty during the Covid-19 pandemic. In facing the spread of Covid-19, the agricultural sector is a priority because it is directly related to national food security. As a national food barn, West Java is affected by the increase in poor people. Pada in 2021, Bandung Regency experienced extreme poverty, which is 2.64%; this will affect food security in particular, in terms of affordability. Therefore, the availability of accurate and fast food security information is needed to prevent and handle food insecurity in order to provide direction and recommendations for preparing programs and policies, especially during the Covid-19 pandemic. This study was based on analyzing differences in food security before and during the Covid-19 Pandemic in Bandung Regency regarding food availability, affordability, and utilization. The analysis used a descriptive quantitative method with a paired sample t-test. The data source is secondary data from the Food Security and Vulnerability Atlas report of Bandung Regency. The analysis shows a noticeable difference between the food security of Bandung Regency before and during the Covid-19 pandemic, namely the decrease in the composite value of food security, especially in affordability. The most significant average increase occurred in the lowest welfare ratio indicator in 2020. Keywords: food security, Covid-19

Abstract

Porang is one of the export commodities whose production is currently intensive by the Indonesian Government. Soft rot disease is one of the obstacles in cultivation and post-harvest of porang, which results in a decrease in productivity and quality of porang. This study aims to isolate pathogenic bacteria that infect porang tubers and determine their morphological and molecular characters. A total of 43 bacteria were isolated from porang tubers with soft rot symptoms from Malang Regency. Ten isolates of them showed positive reactions in the hypersensitivity test. Amylolytic, pectinolytic, mannanase, and proteolytic activities were shown by three bacterial isolates, including B4, B7, and BLUB15, by forming a clear zone around the inoculation point. The results of the decay test showed that B4 isolate had the most severe signs of decay, up to 97.88% in potato tubers and 37.12% in the porang frog. A pair of ExpccR/ExpccF PCR primers successfully detected B4 isolate as Pectobacterium carotovorum subsp. carotovorum (Pcc) in the 550 bp band. Unexpectedly, identifying the other two isolates did not show any similarity to the bacteria that cause soft rot, which was previously known. The two isolates showed similarities to Empedobacter sp. B7 (98.7%) and Pseudomonas sp. BLUB15 (97.6%) as a result of 16S rRNA gene analysis. So far, based on the existing literature, this is the first report of phytopathogenic bacteria causing soft rot outside the genus Pectobacterium and Dickeya.

Abstract

Guano can be used as an organic fertilizer in anticipating fertilizer shortages. This study aims to obtain the right dose of guano for the growth and yield of sweet corn (Zea mays saccharata L). The method used in this study was a single-factor randomized block design, consisting of 4 treatments of doses of guano fertilizer and 4 replications. Fertilizer dosage treatments were: g0 = no guano, g1 = 3 tons guano/ha, g2 = 5 tons guano/ha, g3 = 7 tons guano/ha. Observation parameters consisted of plant height (cm), the number of leaves (strand), the diameter of the stem (cm), the diameter of the ear (cm), the length of the ear (cm), and the weight of fruit/bed (kg). The results showed that the use of guano at a dose of 7 tons/ha was the best dose for plant height, the number of leaves, ear diameter, stem diameter, and cob weight. It was concluded that guano could increase the growth and yield of sweet corn. Keywords: corn, guano, organic fertilizer
