Abstract

Lilium longiforum Thunb.is a potential ornamental plant that has been developed in several indusrtry, such as pharmaceutical industry and floriculture industry. Generative propagation of L. longiflorum is difficult and more effective when propagated asexually through tissue culture techniques. This research aimed to analyze callus induction from L. longiflorum bulb scale and its growth response to the addition of auxin and cytokinin in culture media. This research were tested in two treatments: MS + 3.0 mg L-1 2.4-D + 0.5 mg L-1 BAP, incubated in dark condition for 24 hours (treatment 1) and MS + 1.5 mg L-12.4-D + 1.0 mg L-1BAP, photoperiod 16/8 h (treatment 2). Furthermore, calli were planted on regeneration media (MS + 3.4 mg L-1BAP + 0.09 mg L-1NAA). The result showed that explant in treatment 2 (MS + 1.5 mg L-12.4-D + 1.0 mg L-1BAP, photoperiod 16/8 hours dark/light) is more responsive than treatment 1 on callus induction and subculture treatment. This treatment also produced good quality of calli which were shown in a compact texture, yellowish green colour and 100% survived. Regeneration media succeeded in regenerating calli into indirect shoots by 100%, even though no direct shoots and roots were found in this experiment. This research suggest that treatment 2 can used as an effective protocol on developing L. longiflorum.

Abstract

One of the problems for phosphate fertilizing in ultisol soil is Al and Fe bounding and could be overcome by phosphate solubilizing bacteria activity.This study aimed to obtain the best dose of phosphate fertilizer with phosphate solubilizing bacteria for the production of upland rice seeds of the UBB1 PBM variety (Bangka Belitung University red rice 1) and its effect on seed quality. The research was carried out at the Research and Experimental Gardens – Faculty of Agriculture, Fisheries and Biology, University of Bangka Belitung, from August to December 2020. The design used was a split plot design, the main plot was phosphate solubilizing bacteria (treatment and control), and the subplots were fertilizers. phosphate (P1– quarter dose, P2– half dose, P2–three-quarter dose, P4– full dose). Seeds produced in the field were tested in the laboratory for viability and vigor. In the field, phosphate solubilizing bacteria (Burkholderia sp) can replace half the dose of phosphate fertilizer. This was indicated by the seed weight of plant-1 which did not differ between full dose + control and half dose + treatment. This fact was also identified in the viability and vigor of the seeds in laboratory testing. There was no significant difference in germination rate and vigor index between the two treatments. This finding shows that phosphate solubilizing bacteria can be applied for efficiency of phosphate fertilization and guaranteeing seed production and seed quality

Abstract

Waste is a major problem that is often faced by Indonesian people. The existence of waste that has not been handled properly will have a negative impact on the quality of the community's environment. Waste handling with the bioconversion method with the help of Black soldier Fly (BSF) larvae and EM-4 bio-activator can minimize waste capacity and be useful for the community. This study aims to compare the ability between bioconversion agent and quality of various types of organic waste that use for bioconversion. The research was conducted in January – August 2022 at Experimental dan Research Garden (KP2) Universitas Bangka Belitung and Laboratory of Indonesian Center for Biodiversity and Biotechnology. This study used a factorial randomized block design (RAKF) with 2 factors. The first factor were bioconversion agents consist of 3 levels, P0 (control), P1 (EM-4 activator) (15 ml), P2 (Black Soldier Fly) (5 grams/bio-pond). The second factor were different kind of organic waste materials consists of 3 levels, L1 (pineapple peel waste), L2 (orange peel waste), L3 (bagasse). The results showed that BSF larvae had a potential as bioconversion agent and its ability close to EM-4. Generally, application of bioconversion agent increased the quality of compost compare to without application of bioconversion agent.  Application of bioconversion agent combined with pineapple peel waste had quality close to standards from Ministry of Agriculture No. 261, 2019.

Abstract

Shallot commodity is a strategic commodity and has high economic value and cannot be substituted for other commodities. This research aimed to observe the correlation, direct and indirect effect between growth and yield components characters to shallot yield in the highlands. This experiment was conducted from September to November 2019 in Lembang (West Bandung Regency), Pacet (Bandung Regency), and Samarang (Garut Regency). The research material included 12 shallot genotypes, namely B1 clone, B19 clone, B63 clone, B72 clone, B77 clone, B102 clone, B222 clone, Trisula, Bali Karet, Maja Cipanas, Bima Brebes, and Sumenep. The experiment was arrange in Randomized Block Design (RBD), with 3 (three) replication. The results of the correlation analysis showed that there was a very significant positive correlation between the character of leaf length, and wet bulb weight per clump to wet bulb yields per hectare in all test locations. Leaf length is a character that has a very significant positive correlation and has a very high positive direct effect on the yield of wet bulb  per hectare in all test locations in the highlands. Selection of shallots to increase the yield of wet bulb per hectare in the highlands can be done directly through the growth character, namely leaf length.

Abstract

White pepper production is not in line with the government's extensification and intensification efforts, these are due to disease infection in the pepper plant that tends to increase. Information about disease progression of black pepper plants in production center areas is rarely updated. This research was conducted to observe and determine incidence and severity disease of the black pepper plantations by using the purposive sampling method. The results of the study found three types of disease that infected on black pepper plantations in the South Bangka Regency, namely yellow disease, stem rot disease, and viral disease. The incidence and severity disease are relatively higher in the Tukak Sadai District than others. The incidences of yellow disease, rot stem disease, and viral disease about 3,33 to 90,48 %; 0 to 43,70 %, and 12,5 to 100 %, respectively. The severity of rot stem disease until 43,11 %; and viral disease about 4,58 to 59,57 %.

Abstract

Mungbean is one of the main commodity which are planted in the dry season after planting rice. Even though having a high marketable value, the productivity of mungbean is still quite low because the farmers rarely provide enough fertilizer dosage and use the low growed seeds which resulted directly to the low quality or productivity. This study aims to determine the response of three mungbean varieties in paddy fields with five levels of NPKS (15:15:15:10) fertilizers. The study was consisted of three varieties (Vima-1, 2, 4) and five doses of NPKS fertilizer (100, 200, 300, 400, 500 kg ha-1). The study was applied to the randomized completely block design with three replications. The results showed that plant height, number of clusters, biomass dry weight, and seed yield ha-1 of mungbean are significant different between Vima-1, Vima-2 and Vima-4 varieties, while the addition of NPKS inorganic fertilizers could increase plant height and root weight. The interactions between varieties and the NPKS fertilizer dosage was experienced in the number of pods and seed weight per plant. The highest yield of mungbean was resulted in Vima-1 (2.18 tons ha-1) whereas the lowest yield was obtained by Vima-2 which resulted in seed 1.42 tons ha-1. The application of inorganic fertilizer NPKS (15:15:15:10) 100 kg ha-1 has quite enough to produce an optimum productivity of mungbean in Malang rice fields.

Abstract

Biotic and abiotic stress during cultivation is one of the challenges in increasing upland rice production. Stress can be mild to severe, potentially reducing yield. Knowing the ability of plants to adapt to stressful environments from the start is essential information in the assembly of new high-yielding varieties. This study aims to determine stress in 36 upland rice lines and the adaptability of several upland rice lines to environmental stress. The genetic material used was 36 upland rice lines and two comparison varieties with four replications. The line is planted in Lampung, DI. Yogyakarta and East Java, two locations each. That area has different soil types and elevations. Data were analyzed descriptively and tabulated. In addition, the average scoring of biotic and abiotic stress for each location was calculated. The results showed that biotic stresses found in the plantations were Leaf Blast, Neck Blast, Bacterial Leaf Blight, Brown Spot, Red Striped, Rats, Birds, Rice Leaf Roller, and Stem Borer. Meanwhile, the abiotic stresses found were drought and salinity. From 36 tested lines, it showed that G26 was resistant to biotic stress caused by pests and diseases, G29 was drought-tolerant, and G6 was salinity tolerant.

Abstract

The diversity of genetic material determines the success of cocoa production. improvement and breeding programs. Enrichment of genetic material for Bangka cocoa can be achieved through exploration and characterization of morphological features or characters of accessions, clones, and/or varieties. To determine the level of diversity of qualitative and quantitative traits. Morphological exploration and characterization was aimed at identifying the diversity of Bangka cocoa as an effort to increase the efficiency of utilization of local genetic material. The research used survey, and direct characterization (purposive sampling). Exploration to obtain a cocoa plant passport consists of accession number, accession name, location of origin, owner's name, age of plant, and land area. Characterization to obtain the identity of qualitative and quantitative characters from leaves, flowers, fruits, and seeds refers to “The Systematic Description of Cacao Clones. The results of the exploration-characterization obtained 29 accessions of cocoa from Bangka, which had very diverse morphological characters. Diversity is evidenced by wide phenotypic variability even though it has narrow genetic variability, and the similarity level of some accessions is quite low, namely <50%.

Abstract

Soybeans can be cultivated in Entisol. However, soybean cultivation on Entisol land has problems, including low soil fertility. Providing compost and NPK is an alternative to overcome this. The research objective was to determine the best type of compost and NPK fertilizer dosage for soybean growth and yield in entisol. The research has carried out in the Entisol Bengkulu field from August to November 2020. The research design used a Complete Randomized Block Design (CRBD) with 2 factors including: the type of compost organic fertilizer consisting of: P1 = Widelia trilobata, P2 = Tithonia diversivolia, P3 = oil palm empty bunches, and P4 = Eichhornia crassipes and the NPK fertilizer dosage consisting of: N0 = 0 kg ha-1, N1 = 150 kg ha-1, N2 = 300 kg ha-1, N3 = 450 kg ha-1. Observation variables include plant growth and yield and supporting observations which include the results of initial soil analysis and climate data during the study. The results showed that NPK dosing had a significant effect on the variables of plant height, number of leaves, number of branches, root wet weight per plant, and dry weight per plant. However, the application of compost did not significantly affect all variables. Meanwhile, there was no interaction between the application of compost types and NPK dose on the growth and yield of soybean in entisols. The application of compost types and NPK fertilizer doses up to 450 kg ha-1 has not improved the growth and yield of soybeans in entisol fields.
