Abstract

Fossil fuel sources are non-renewable energy sources and someday will experience scarcity due to the increasing population; it is necessary to look for alternative fuels. Several renewable energies that can replace fossil fuels are water, solar energy, wind, thermal energy, and biomass energy. One biomass energy from plantations is biomass from oil palm plantation waste. Riau Province is Indonesia's largest palm oil producer, with a total land area of ​​2.89 million until 2021. The results of harvesting coconuts will produce waste, i.e., oil palm shells. Oil palm shells can be treated with pyrolysis technology. In the pyrolysis process, three products are produced: liquid, solid (biochar), and oil products (bio-oil). In this study, the pyrolysis product of oil palm shell waste in the form of biochar was used as raw material to produce bio-briquettes. Producing bio-briquettes resulted from pulverized biochar pyrolysis, mixed with tapioca flour adhesive with a percentage of 4% and 8%. Then, the biochar mixture with adhesive was put in a mold and compressed. The results of the bio-briquettes were tested for water content, ash content, volatile matter content, and calorific value. The test results were compared with the Indonesian National Standard (SNI) No. 01-6235-2000. The research results on bio briquettes from the pyrolysis of palm oil shell waste showed the best results at 4% reactant content with 4.45% water content, 5.1% ash content, volatile matter content 40.40%, and the calorific value was 5,999.93 cal/gram.

Abstract

Grammatophyllum stapeliiflorum is one of the most popular orchid species because of its beauty and is characterized by the shape of the flower stalk that sticks down and the brown flowers with white and yellow spots that look like drops of water or sad. This type of orchid is almost extinct and is rarely found in its natural habitat, so it is necessary to perform in vitro propagation of orchids. The culture in vitro method is one of the most effective methods for propagating rare orchids. This study aimed to determine the effect of adding potato water on protocorm growth and determine the best concentration for the growth of G. stapeliiflorum protocorm in vitro. This study used a Completely Randomized Design (CRD) with the addition of potato water (concentrations 0, 50, 100, 150, and 200 ml/L) on Murashige-Skoog (MS) medium. The results showed that the percentage of live explants was 100% in all treatments. The addition of potato water to MS medium had no effect on the percentage of live explants but still affected the growth percentage of Protocorm-like bodies (PLBs) in vitro. The best concentration of potato water for the protocorm growth of G. stapeliiflorum in vitro to MS medium was at a concentration of 150 ml/L, which was indicated by the highest percentage of PLBs growth at 100% and the color of PLBs green (2.5GY 6/8) compared to other potato water treatments and controls.

Abstract

Welsh onion (Allium fistulosum L.) is one of the horticultural commodity crops with high consumer value in Indonesia, but production remains low. Efforts to increase the production of Welsh onion can be performed by induction of anti-mitotic substances. Catharanthus roseus leaves contain anti-mitotic alkaloid compounds that promote growth and yield. This research aimed to analyze the effect of extract C. roseus leaf on the growth and morphology of Welsh onion. This research was conducted in Kejajar, Wonosobo, Central Java, followed by analysis in Plant Physiology and Breeding Laboratory, Diponegoro University. This research used a Randomized Block Design (RBD) factorial with three concentrations; 0.05%, 0.1%, and 0.2%, and three levels of soaking duration; 6, 9, and 12 hours. The data were analyzed statistically using ANOVA followed by Post-hoc Test using Honestly Significant Different (HSD) at 5%. The result showed that applying 0.05% C. roseus leaf extract significantly affected sprouting time, number of tillers per plant, number of leaves per plant, fresh weight, and stomatal density. In addition, the interaction between 0.1% C. roseus leaf extract treatment and 12 hours of soaking duration increased root length by 16.67 cm.

Abstract

The effectiveness and efficiency of operations are essential in increasing the production and profitability of oil palm plantations. It can be performed through the application of precision farming principles. One of the main obstacles for oil palm to produce optimally according to their potential is disease attacks on leaves. However, the weakness of the manual observation method is the limited ability of the observer in assessing a disease that attacks leaves. Therefore, it is necessary to have a companion system for smallholders to detect and control diseases with minimal environmental impact properly. Most of the visual-based identification efforts in precision agriculture use the concepts of computer vision and machine learning. This study's problem was the need for machine learning and computer vision-based software to identify diseases to realize sustainable oil palm plantation practices. Disease detection includes a description of the name of the disease in oil palm plantations. In this study, designing a disease recognition based on computer vision and machine learning had used the convolutional neural network (CNN). The application used the Android operating system in real-time. The test results on the model showed that the model had been able to predict with an accuracy rate of 85.5%

Abstract

The efforts to increase paddy yields are integrated with disease control. Bacterial Leaf Blight (BLB) is a disease that attacks paddy plants caused by Xanthomonas oryzae bacteria. So far, the control carried out by farmers is by spraying bactericides, planting disease-resistant varieties, and rotating plants that are not pathogenic hosts. However, this method of controlling has not obtained satisfactory results. Therefore, we need an alternative option in overcoming BLB disease, namely using bacteriophages as biocontrol agents in infecting Xanthomonas oryzae bacteria. This study explored the potential of bacteriophages isolated from soil samples near paddy plants' root areas and tested their particle's stability. The stages of experiments were soil sampling, isolation, purification, propagation, and pH stability examination. The results showed that the Xanthomonas oryzae bacteriophages had been isolated, purified, and propagated with the coding Kalibening 1 (XB1), Kalibening (XB2), and Kalibening 3 (XB3). The results of the pH stability test on the three samples also showed that the Xanthomonas oryzae bacteriophages experienced particle instability and the titer tended to drop in the pH range of 3-5, while the Xanthomonas oryzae bacteriophages tended to be stable at neutral and alkaline pH 7-11, particularly XB1 and XB2 bacteriophages.

Abstract

Trichoderma sp. is a saprophytic fungus found in various environments, one of which is in the rhizosphere of oil palm plants which can be used to control Ganoderma and increase the resistance of oil palm plants from stem rot disease. This study aimed to characterize the morphology of Trichoderma spp. origin of peat land in oil palm plantations in Kampar Regency and screening the potential in controlling Ganoderma sp. Trichoderma spp. from oil palm rhizosphere was collected from the smallholder oil palm plantations in Deli Makmur Village, Kampar, Indonesia. This research was conducted by several observations, such as the hypovirulence test; identification of the morphology of Trichoderma spp. fungus; growth and diameter test of Trichoderma spp. fungus; test of the inhibitory ability of Trichoderma spp. fungus against Ganoderma sp. LPTUNRI-Gan002 isolate; test for hyperparasitism of the fungus Trichoderma spp., which has high antagonistic power against Ganoderma sp. isolate. Six Trichoderma spp. isolates had morphological characteristics similar to two species, i.e., Trichoderma harzianum (LPTUNRI-Trc001, Trc004, Trc005, and Trc006 isolates) and Trichoderma asperellum (LPTUNRI-Trc002 and Trc003). LPTUNRI-Trc003 had the highest diameter (90 mm), growth rate (32.66 mm/day), and the highest ability to suppress Ganoderma sp. LPTUNRI-Gan002 (91.03%) compared to the other five isolates.

Abstract

Maize has a wide diversity. The diversity of maize exceeds that of any other species and is used and conserved by traditional maize farmers. The way to find information about maize diversity is to evaluate the maize genotype through plant characterization. Plant characteristics include observing the qualitative and quantitative traits to identify and select appropriate parental species for use in forming or developing varieties. This study aimed to examine the diversity of agronomic traits in 12 genotypes of colored maize; Meanwhile, Bonanza (sweet maize) was used as a control. An augmented design with the basic design of a completely randomized design was used as a research experiment. From the agronomic data, cluster analysis between characters was carried out based on the Euclidean distance coefficient using the MVSP application to determine the relationship between genotypes. The observations of quantitative and qualitative traits showed that the characteristics of plant height, seed color, stem color, tassel color, and cob hair had heterogeneous diversity. However, sweetness, cob color, seed type, and seed row arrangement had homogeneous diversity in the male and female flowering age characters. Based on the dendrogram results, the twelve genotypes tested and the control showed that these genotypes were different varieties in one genus, i.e., Zea L. because they had a similarity value above 80%.

Abstract

This research aimed to determine the potential of endophytic Trichoderma sp originated from oil palm plant tissue as a biological control agent and its molecular identification. The potency assay was carried out using a completely randomized design consisting of three isolates of Trichoderma sp. from different plant tissues (TR01 from root tissue, TS01 from stem tissue, and TM01 from midrib tissue) with inhibitory ability parameters. The inhibition of the growth of G. boninense was performed at the concentration of 15% and 20%, and the molecular identification of Trichoderma sp. endophyte isolates was analyzed using BLAST software. The results showed that Trichoderma sp. TM01 isolate had larger inhibitory than the other isolates on days 3 and 4 by 60% and 68%. TM01 isolate also showed inhibition to the growth of the G. boninense at 15% and 20%, with the percentage of inhibition reaching 71.79% and 82.05%. Based on phylogenetic analysis, the three endophytic isolates of Trichoderma sp. were closely related to Trichoderma virens.
