Morphophysiological and Vanillin Quality Evaluation of Vanilla Plants (Vanilla planifolia Andr.) under Water Stress
type: item
description: Vanilla (Vanilla planifolia Andr.) is a globally popular flavoring cultivated in tropical regions such as Madagascar, Indonesia, and Mexico. Due to global climate change, particularly the El Niño phenomenon, droughts have become more frequent, impacting water availability and quality for vanilla plants. This study addresses these challenges by examining the plant’s responses to drought at a vanilla plantation in Yogyakarta, Indonesia, over two years. A completely randomized design was used, testing five water stress levels (100%, 50%, 25%, 150%, and 200% field capacity). Variables measured included relative water content, physiological activity, chlorophyll, proline content, leaf total acid, photosynthesis efficiency, and morphological traits. Data analysis was performed using ANOVA and Tukey’s HSD test. Vanilla plants exhibited significant physiological and morphological changes in response to varying water conditions. Severe drought (25% water stress) led to reduced relative water content, chlorophyll levels, and CO₂ assimilation, alongside increased proline accumulation. Moderate drought (50% water stress) had a lesser impact. Under field capacity (100%) and excess water (150% and 200%), plants maintained higher relative water content and chlorophyll levels, efficient CO₂ assimilation, and optimal morphological traits. The presence of proline under excess water suggests a dual stress response to drought and waterlogging. Beans from severely drought-stressed plants showed a significant decrease in vanillin content and weight. Identifying and developing vanilla varieties with greater tolerance to water scarcity is essential to ensure sustainable production in the face of climate change.

The Effect of 2,4-D and BAP On The Multiplication of Vanilla (Vanilla planifolia Andrews)
type: item
description: Vanilla is a plant that has many benefits, high selling value and potential to be developed. Conventional propagation of vanilla such as through cuttings has not been effective, so a more effective method of propagation is needed, one of which is propagation through tissue culture. In-vitro propagation of vanilla can be through shoot multiplication to produce fast plantlets. One of the successes of shoot multiplication is influenced by the hormone given. This study aims to determine the effect of giving a combination of 2,4-D and BAP on the multiplication of vanilla shoots. The study design used CRD with a combination factor of 2,4-D (concentration 0.5 mg/L, 1.0 mg/L, and 1.5 mg/L) and BAP (concentration 0.25 mg/L, 0.5 mg/L, and 0.75 mg/L). The explants used were vanilla stem segments. Based on the research results, the combined treatment with concentrations of 2,4-D 1 mg/L and BAP 0.5 mg/L had a very significant effect on the multiplication of vanilla shoots with the fastest emergence of shoots with an average of 6.6 wap, the highest number of shoots was 7 shoots, and the survival percentage was 100%.

Application of Gypsum Waste and Organic Fertilizer on the Growth and Yield of Peanut (Arachis hypogea L.) in Ultisol Soil
type: item
description: Peanut is an important agricultural commodity in Indonesia as a protein and vegetable oil source. Soil conditions in Indonesia are usually ultisol soils that have low pH and nutrients, this is an obstacle in peanut cultivation. This study was conducted to determine the effect of a combination of calcite sources and organic fertilizers on the growth and yield of peanut in ultisol soil. This research was conducted from May to August 2024 at UPTD Balai Benih Pertanian Air Pelempang, Bangka Regency. The research used a split-plot randomized group design. The main plot was without a calcite source (P1), agricultural calcite (P2), and gypsum waste (P3). Subplots were commercial compost (K1), chicken manure (K2), and cow manure (K3). Data analysis was performed using an analysis of variance with a significant level of 95% and a follow-up test with Duncan's Multiple Range Test with a significant level of 95%. The results showed that the treatment of calcite sources from agricultural calcite was better than the treatment of gypsum waste and without calcite sources. The treatment of organic fertilizer from chicken manure was better than cow manure and commercial compost. The combination that gave the best results with the highest value was agricultural calcite and chicken manure fertilizer, which affected all parameters except the percentage of effective root nodules, root dry weight, and flowering age. Gypsum waste has the potential to be a substitute for agricultural calcite when combined with chicken manure fertilizer, as it does not have significant results with agricultural calcite.

Effectiveness of Essential Oil and N-Hexane Extract of Beluntas Leaves as Natural Insecticides with Bioindicators of Hongkong Caterpillars
type: item
description: Natural insecticides are pest control materials derived from natural sources such as plants. The use of natural insecticides is very important because it has a lower cost, is safe for living things and does not pollute the environment, so this study aims to determine the activity of essential oils and n-hexane extracts of beluntas leaves (Pluchea indica L.) as natural insecticides with bioindicators of Hong Kong caterpillars (Tenebrio molitor). Isolation of essential oils was carried out using the steam distillation method and extraction using the maceration method. Insecticide activity tests used the contact poison method and the residue method, with variations in extract and essential oil concentrations of 1%, 3%, 5%, 7%, 10%, 20%, 30% (v/v) and positive controls, namely Hippo insecticide and negative control tween 80. The results of the isolation of essential oils from beluntas leaves produced a yield of 2%, while extraction using the maceration method produced a yield of 1.84%. The results of the insecticide activity test using the contact poison method were more effective than the residue method. The insecticidal activity and n-hexane extract are more effective than essential oils, this is due to the differences in the content of secondary metabolite compounds contained in the extract and essential oil.

Combining Ability of Inbred Lines, Performance, and Heterosis of Single-Cross Maize (Zea mays L.) Hybrids
type: item
description: The utilization of superior hybrid varieties is pivotal in enhancing national maize productivity. Therefore, the continuous development of cultivars specifically adapted to distinct agroecosystems remains imperative. To that end, this study evaluated six inbred lines and 15 single-cross hybrids derived from a half diallel mating design to assess the combining ability of these inbred lines and examine the agronomic performance and heterotic expression manifested in the resulting hybrids. All genotypes, including the hybrids, inbred parents, and a check variety (P32), were tested using an RCBD with two replications in Nagari Situjuah, West Sumatra, Indonesia. The data were analyzed using F-tests followed by a planned LSD test with SAS software at the 5% significance level. PCA and path analysis were performed using RStudio, while GCA and SCA were analyzed using Diallel-SAS software. Results showed that the UZ 9 line performed the highest GCA for growth, flowering and yield-related traits. Hybrids UZ 3><UZ 9 (H2), P137-1><R2 (H14), and CLYN><R2 (H15) exhibited the best SCA values, coupled with superior agronomic performance, positive and high heterosis, heterobeltiosis, and standard heterosis for yield, achieving up to 11 tons hectare⁻¹, comparable to P32. PCA further supported these findings, which revealed that H2, H14, and H15 were associated with shorter flowering, harvesting periods and higher kernel yield. Path analysis identified kernel weight ear⁻¹ as the most influential variable affecting kernel yield hectare⁻¹. These findings highlight H2, H14, and H15 as promising hybrids with strong potential for further development and evaluation before release as new superior hybrid varieties.

Breeding Methods for Anthracnose Resistant Chili Pepper in the Last Decade: A Review
type: item
description: Chili is one of the most economically valuable commodities cultivated worldwide. The high interest in chili can be attributed to capsaicin, which provides a spicy sensation when consumed. The level of interest in chili cultivation does not necessarily correlate with the yields obtained. The loss in production and yield can be attributed to the disruption of the Colletotrichum spp., which causes anthracnose disease. Breeding for anthracnose-resistant chili has been a focus of research for many scientists in various countries. Conventional and molecular methods are employed in the production of anthracnose-resistant chilies. This study will examine a range of articles and investigate the development of anthracnose-resistant chilies. The article was searched in the Scopus database. The articles were filtered based on the publication date range of 2014 to 2024, resulting in 343 articles. Furthermore, the articles were evaluated based on predetermined criteria, resulting in the identification of 22 articles. The breeding of anthracnose-resistant chili plants employs a range of conventional and molecular techniques to identify the most suitable lines. Various techniques, including crossing and different kinds of selection, were employed and validated through the development of molecular markers. Markers and genes have been identified, including RA80f6_r1, RA80f6_g1, RA80f6_g2, and RCT1, which are responsible for anthracnose resistance. This review provides an overview of the various anthracnose-resistant chili breeding methods.

type: item
description: Mungbean is one of food plants that has important role as a source of nutrition. One of the important macronutrient elements which its deficiency can disrupt the photosynthesis process resulting in reduced mungbean growth and yield is Mg (magnesium). Research aimed to determine responses of several varieties to application of different doses of kieserite fertilizer and to obtain the best dose for each varieties. Experiment was arranged in a randomized block design (RBD) with a two-factor factorial pattern. The first factor was four varieties i.e. ‘Vima 1’, ‘Vima 3’, ‘Vima 5’, and ‘Vimil 1’. Second factor was four levels of kieserit fertilizer dosage (0, 50, 100, and 150 kg ha-1). Observed variables were yield and yield components. Data were analyzed using analysis of variance and Duncan's test at 5% α level. Results showed that the responses of four varieties used were relatively the same to the dose of kieserit, and dose aplication of kieserit 50 kg.ha-1 could increase yield. Highest yielding variety was Vima-5 variety with highest number of pods and yield per plant. While the lowest yielding variety was Vimil-1 variety which had lower seed size (weight 100 seeds) than of other varieties.

type: item
description: The success factor in developing arbuscular mycorrhizae fungal (AMF) biofertilizers the source of propagules, which is determined by ecological factors. The compatibility between AMFs is important in deciding whether the biofertilizer produced can be used efficiently. The research aims to study and obtain location-specific AMF from two different ecosystems on the growth and yield of cauliflower plants with efficient fertilization. The research was conducted in Pontianak City, West Kalimantan, from June to November 2023. The research method used a completely randomized factorial design. The first factor is the ecosystem source of AMF propagules (without AMF, AMF from peat ecosystems, and AMF from dry land ecosystems). The second factor is the level of NPK fertilization (100%, 75%, 50%, and 25% of the recommended dose). The research results obtained show that the application of AMF from peat ecosystems and dry land as a biological fertilizer is able to support the efficiency of NPK fertilization in increasing the growth and yield of cauliflower plants up to a fertilizer level of 50% of the recommended dose.

The Relationship Between Tungro Disease Score and Loss of Rice Yield Components
type: item
description: The Tungro disease is a significant issue that impedes rice production. It is spread by green leafhopper vectors carrying the RTBV and RTSV pathogens. The infection causes a decline in various components of rice yield and is categorized based on a scoring system ranging from 1 to 9. The objective of this study was to investigate the correlation between the scoring values and yield loss, as well as determine the production factor that had the greatest impact on yield loss for each score. The research was conducted at the IP2TP Tungro Disease Research Station between August and October 2020. A purposive sampling technique, which involved the direct observation of tungro-affected rice fields, was employed as the research method. A score was assigned to 5 clumps of plants for each case. Data analysis was performed using simple regression, correlation, and PCA. The findings indicate that with the exception of the empty grain parameter, which increased along with the scoring value, each increment in the Tungro score resulted in a decrease in the yield variables. The components of yield that declined in all scores as a result of Tungro infection included total grain weight, weight of 100 seeds, total grain count, and total grain content.

The Relationship Between Soil Fertility and Basal Stem Rot Disease in Oil Palm Plantations
type: item
description: In oil palm, Ganoderma boninense causes stem rot disease, which is often difficult to control, and soil fertility status is related to the ecology of G. boninense as a soil-borne pathogen. Therefore, this study aims to evaluate the relationship between soil fertility and stem rot disease as well as appropriate management methods to control the disease. This was carried out at the Nusantara Plantation Company's 7, Unit Kiwah Rejosari-Pematang from June 2021 to January 2022. The determination of observation blocks was carried out selectively using three blocks of land attacked by Ganoderma boninense with the same criteria for the year of planting and the same soil type. Each block consists of five plots. Each plot consisted of five sub-plots, consisting of 3 oil palms for disease severity assessment and soil sampling. The soil for each subplot was composed of 15 samples, which were analyzed for physical and chemical properties of the soil. Determination of fertility status based on the soil research manual published by the Indonesian Bogor Soil Research Center with parameters from the analysis results. The limiting factor for fertility is the cation exchange capacity of the soil, which ranges from 10.07 meq/100 g to 17.68 meq/100 g, and the C-organic content, which ranges from 0.40 to 1.15%. According to chi-square analysis, this fertility-limiting factor is related to disease severity. Therefore, management needs to be done by adding organic matter to the soil, practicing organic or inorganic fertilization, and following the principles of cultivating healthy oil palm plants.

Effect of Glomus etunicatum Inoculation on The Biochemistry of Tomato (Solanum lycopersicum L.) Planted in Salt Stress
type: item
description: The presence of salt levels can cause an important abiotic stress today. Plants have a special strategy for dealing with salt stress. The purpose of this study was to determine the effect of the inoculation of the arbuscular mycorrhizal fungus Glomus etunicatum on several biochemical parameters of tomato (Solanum lycopersicum L.) grown under high levels of salt stress conditions. This study used a randomized block design with a factorial pattern and five replications. The first factor was with and without inoculation of the fungus G. etunicatum. The second factor was several concentrations of NaCl (0, 50, 100 and 200 mM). Parameters observed were levels of phosphorus, root infection, concentrations of chlorophyll and carotenoids, activity of antioxidant enzymes (superoxide dismutase and catalase) and levels of malondialdehyde at the end of observation (day 45). The results showed that the increasing concentration of NaCl, decreased the levels of phosphorus, the concentration of chlorophyll and carotenoids as well increased the activity of superoxide dismutase, catalase and malondialdehyde levels. While the G. etunicatum inoculation treatment had the opposite effect from the NaCl treatment. Likewise, the parameters of root infection decreased in tomato plants inoculated with G. etunicatum with increasing NaCl concentration treatment. The conclusion of this study is that the presence of arbuscular mycorrhizal fungi can reduce the negative impact of salt stress on tomato plants.

The study used a factorial randomized block design. The first factor was the concentration of PSB (0, 10, 20 ml plant-1) and the second factor was the dose of bokashi Tithonia diversifolia (0,10,20,30 t ha-1). The parameters observed were soil organic C, available P, RSR, leaf area, harvest index, and weight of corn without husks. The results showed that PSB inoculation increased C-organic and P-available, harvest index and weight of corn without husks. Application of bokashi paitan increases leaf area. PSB inoculation of 20 ml plant-1 improved soil C-organic and P-available as well as maize yields grown in post mine sandspits soil.

The Effect of Fertilizer Concentration of STMJ Plus (Milk Eggs Molase Trichoderma sp. and Fruit Waste) on the Growth and Production of Two Lettuce Varieties (Lactuca sativa L.)
type: item
description: Increasing lettuce production will be done by improving cultivation inputs, such as increased nutritional needs. An alternative organic fertilizer that can be used is made from spoiled milk, eggs, Trichoderma sp. molasses, and fruit waste, or STMJ Plus for short. STMJ Plus Fertilizer acts as an organic nutrient to encourage plant growth. This study aimed to determine the effect of the interaction between STMJ Plus fertilizer concentrations and lettuce varieties on the growth and yield of lettuce plants. The experiment was carried out in a factorial manner using a completely randomized design (CRD) consisting of 2 factors with 4 replications. The first factor is the concentration of STMJ Plus fertilizer consisting of 4 levels: P0: without fertilizer; P1: 5 ml L-1; P2: 10 ml L-1; and P3: 15 ml L-1. The second factor was the variety, which consisted of 2 levels: V1: Grand Rapids and V2: Red Rapid. The results of this study that the interaction of STMJ Plus fertilizer concentrations and lettuce varieties showed highly significant differences in plant height and plant fresh weight variables. The combination that gave the best effect was the concentration of 15 ml L-1 on the Red Rapid (P3V2).

Chemical Quality Of Compost Produced by Bioconversion Of Various Organic Waste by Using Black Soldier Fly and EM-4
type: item
description: 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.
