Abstract

The direct seeding of rice (DSR) system has been widely practiced in various Asian countries because it is considered more efficient in water and labor and provides better benefits than transplanting systems. However, improvements in the management of this system practice are still needed, especially in cropping patterns and the use of appropriate varieties. This study examines the physiological characteristics, yield components, and yields of rice genotypes in transplanting and DSR systems. This research was carried out in the field with transplanting and DSR cultivation systems (drill and broadcast sowing) and used four superior lines and one national variety. A total of 25 treatment combinations were designed using a split-plot randomized complete block design (Split plot-RCBD) with three replications for each treatment. The results showed that rice grown with DSR had no different level of greenery and photosynthesis rate than rice in transplanting cultivation, but produced lower panicle length, the number of grains per panicle, the number of filled grains, and faster flowering time. Genotype IPB193-F-17-2-3 produced the highest productivity in wet DSR (drill and broadcast sowing) and dry DSR (drill sowing). Genotype IPB193-F-38-2-1 had the highest productivity in transplanting techniques and dry DSR (broadcast method). The productivity of the Ciherang variety in the DSR system (drill method) was not different from the transplanting system. This finding indicates that the direct seeding system using the drill method is promising for further development.

Abstract

Urea fertilizers and biofertilizers play an important role in potato (Solanum tuberosum L.) cultivation, but urea fertilizers are volatile and leach out easily that reduce their effectiveness. Urea coated with beneficial bacteria-enriched organic matter is expected to increase nitrogen used efficiency. The purpose of the experiment was to determine the ability of bacterial-coated urea (BCU) included Bacillus and Azotobacter to improve the growth, nutrient status and yields of potatoes grown in field; as well as to reduce urea dose. The experiment was setup in randomized block design with five treatments and six replications. The treatments were four combinations of the dose and formulation of BCU; and conventional urea fertilizer as control treatment. Application of both BCU formulation increased plant height as well as N and P uptake particularly when the recommended dose was used.  In contrast, the doses and formulation of BCU did not affect chlorophyll content. Application of BCU-A or BCU-B at the rate of 200 kg/ha increased tuber weight by 59% and 81% respectively.  Both high and low dose of BCU did not reduce the vegetative growth and yield compared to the plants fertilized with conventional urea. This experiment showed that BCU is considered to reduce the rate of Urea in potatoes cultivation.

Abstract

The porang plant (Amorphophallus muelleri B.) is a tuber plant. Porang plant propagation still uses conventional methods by using seeds or frogs that experience dormancy and take a long time to make seeds. The tissue culture technology approach through organogenesis is a solution for the supply of large-scale porang seed material. The research aims to determine the effect of TDZ (Thidiazuron) on the formation of organogenesis. This study used porang leaf explants grown on MS media. The research design used a completely randomized design with one factor, namely TDZ hormone at concentrations of 0 mg/L, 1 mg/L, 2 mg/L, 3 mg/L, and 4 mg/L. The results showed that leaf explants on the addition of TDZ hormone could form organogenesis indirectly, but gave a response to form shoots multiplication. TDZ concentration of 2 mg/L gave the highest proportion value in the parameter of callus formation power of 95%, regeneration power of 88%, and  number of shoots of 10.2 shoots.

Abstract

Pests and diseases of maize plants have the potential to cause crop failure. Lack of information and knowledge about plant pests and diseases and limited field extension workers lead to errors in diagnosing maize pests and diseases. This results in inappropriate crop management that decreases production. Therefore, farmers need a tool to detect pest and disease attacks through physical symptoms seen on plants in the field. This research aims to produce an Agricultural Information System, namely an android-based expert system to detect pests and diseases in corn plants. The method used is software with prototyping to get an overview of the application to be built through a prototype application design and then evaluated by the user. The research stages include; gathering needs, building prototypes, evaluating protoype, coding the system, testing the system, evaluating the system, and using the system.  The result is the symptoms of pest and disease attacks on corn plants in the field, can be detected through the form of symptoms that are matched with images and characteristics of symptoms displayed on the Agricultural Information System software installed on android-based mobile phones or Tablets. Test results from 28 respondents showed that the success rate of detection of pest symptoms on corn plants was 75%, and for disease symptoms was 90%.

Abstract

In line with the increase number of populations, the shallot demand is also increase. Thus, some efforts are needed to increase the shallot production on the degraded agricultural land, especially on ultisol. This study aimed to (1) identify the best dose of organic matter and mycorrhiza and the interactions between these two treatments in increasing shallot production on ultisol, (2) analyze the improvement of chemical properties of ultisols using mycorrhiza and organic fertilizer, and (3) measure the increase of vegetative and generatif (production) growth of shallot using these treatments. The study was designed by factorial randomized block design  with some levels. Treatment 1 (Mycorrhiza), M0 = Control, M1 = 10 g/polybag, M2 = 20 g/polybag, M3 = 30 g/polybag, M4 = 40 g/polybag, and Treatment 2 (Organic Fertilizer), P0 = Control, P1 = organic fertilizer (0.6 kg/polybag), P2 = organic fertilizer (1.2 kg/polybag), P3 = organic fertilizer (1.8 kg/polybag), P4 = organic fertilizer (2.4 kg/polybag). The results show that the mycorrhiza treatment just give the significant effect on the paramters of the wet and dry shallot weights. The highest result was found in the M4 treatment (13,9 dan 1,79 gr) and the lowest in the M0 treatment (7,89 dan 0,86 gr) for the wet and dry shallot weigths respectively. The organic fertlizer gives significant effects on all parameters, for the highest output was found in the P3 (30,24 cm, 38,47 leaves, 12,75 gr dan 1,58 gr) dan the lowest from P0 (12,58 cm, 9,57 leaves, 5,46 gr dan 0,86 gr) for the parameters of the height, number of leaves, wet weight and dry weight, respectively. The interaction between two paramters did not give the significant effect on the wet and dry weights. Fortunately, the interaction of the M4P4 treatment give significant effect on the height parameter (37,17 cm) and the M1P3 treatment give significant effect on the parameter of the number of leaves (46 number of leaves).

Abstract

Cililin is one of the robusta coffee producing regions in Indonesia, but there are still many people who do not know robusta coffee from Cililin, so an effort is needed to improve its quality. Coffee that goes through heating stages such as drying or roasting will cause several other chemical ingredients to change. Coffee processing can affect the characteristics and taste of the coffee produced. Soaking with sorbitol solution can retain moisture (humectant) in food and in processing that undergoes high temperature treatment so that it will not cause browning reactions One of the stages carried out in coffee processing using high temperatures is the roasting process. Therefore, a study was conducted to determine the effect of the difference in sorbitol concentration with roasting level on the characteristics of the Cililin robusta coffee products produced. This study consisted of two factors, namely sorbitol concentration (a1=10%, a2=15%, a3=20%) and roasting rate (b1 = Light Roast, b2 = Medium Roast, b3 = Dark Roast).Data processing using Two Way Anova on SPSS application version 26.0. The results showed that concentration had an effect on water content, color test and organoleptic response in color, aroma, and texture attributes, but did not affect the characteristics of caffeine levels, and pH. Roasting rate affects coffee characteristics, namely moisture content, caffeine content, pH, color test, and organoleptic response in color, aroma, and texture attributes. The interaction between sorbitol concentration and roasting rate affects the characteristics of robusta cililin coffee, namely moisture content and color test. However, it has no effect on the characteristics of caffeine levels, and pH.

Abstract

Sorghum (Sorghum bicolor L. Moench) is an alternative food commodity with significant potential for development in Indonesia. However, its genetic diversity in Indonesia is relatively low. The low genetic diversity of sorghum prompts efforts to improve and search for new sources of genetic diversity, including through plant breeding. Radiation-induced mutation is a plant breeding technique aimed at obtaining new traits that are not present in the parent plants. Gamma ray irradiation can damage DNA, and during the repair process, DNA undergoes new mutations induced randomly. This study aims to investigate the agronomic characteristics, genetic diversity, and relationship among plants that have been irradiated with gamma rays using the Random Amplified Polymorphic DNA (RAPD) molecular markers. In this study, local sorghum varieties from Bandung, Demak, and Jember  were subjected to gamma ray irradiation at doses of 0 Gy, 300 Gy, and 500 Gy to induce genetic diversity. The application of gamma ray irradiation doses had a significant impact on parameters such as viability, vigor, and morphology. The isolated DNA was analyzed using the Random Amplified Polymorphic DNA technique. OPA-12 showed the highest level of polymorphism among the four primers used. The bands produced by the four scored primers were analyzed using the NTSYSpc program to determine the level of relatedness between genotypes. The genetic distance between genotypes was considerably wide, ranging from 0.1 to 0.46, indicating the potential for crossbreeding
