Other species that produced honey, albeit with infrequent cultivation, include A. dorsata, A. florea, and some stingless bees, including Trigona and Melipona. Different types of honeybees were known to affect the quality of honey. Hence, this investigation aimed to conduct a meta-analysis to examine the similarities in honey quality between honey sourced from beekeeping and wild honeybees. Data analysis was performed using the OpenMEE software, facilitating the calculation of effect size and standard error. The effect size and common error data were subsequently organized into separate columns within a CSV file. This CSV file was then imported into the JASP 0.16.2 software to conduct heterogeneity and Egger tests to detect potential publication bias. The findings indicated significant disparities in the quality of honey produced by beekeeping, wild, and stingless bee honey, as determined by various parameters, including pH value, moisture, total sugar, acidity, HMF (hydroxymethylfurfural), and diastase enzyme levels (p < 0.05). According to the results of the meta-analysis, honey from beekeeping exhibited superior quality to that of wild and stingless bees. However, the average values of all parameters still adhered to the established honey quality standards set by the Standar Nasional Indonesia and the International Honey Standard (IHS). \u0000 \u0000Keywords: honey, honeybees, meta-analysis, physicochemical quality","PeriodicalId":31211,"journal":{"name":"Jurnal Ilmu Pertanian Indonesia","volume":"42 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140461453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improving the productivity of pepper can be done through sustainable land management based on the characteristics of soils and their potential. Therefore, land suitability evaluation is needed to maximize land potential and minimize inhibiting factors for pepper plant growth. This study evaluated the characteristics, potential, and distribution of suitable land for pepper plant development in Tanggamus Regency, Lampung Province, Indonesia. Land suitability was evaluated by matching land characteristics with land suitability criteria for pepper plants. This criterion consists of four classes, namely highly suitable (S1), moderately suitable (S2), marginally suitable (S3), and not suitable (N). The soil's climate and physical and chemical properties were the land characteristics data used. Potential land availability was arranged based on land suitability classes by considering existing land use and forest area status. Soil types in Tanggamus Regency are Inceptisols, Entisols, Alfisols, Andisols, Oxisols, and Ultisols, with the most extensive distribution of soil types being Oxisol (Typic Hapludox). The distribution of relief in Tanggamus Regency is dominated by mountainous areas with very steep slopes (slope >40%). Land suitability classes are moderately suitable (S2), marginally suitable (S3), and not suitable (N) with limiting factors, namely drainage, texture, soil pH, and erosion hazard/slope. Improvement can be made by planting according to contours, planting cover crops, applying lime and organic matter, and ensuring balanced fertilization. The development of pepper plants in Tanggamus Regency can be achieved through diversification and extensification, with a total area of potential land that can be developed of 73,995 ha. \u0000 \u0000Keywords: land potential, land evaluation, limiting factor, pepper, soil characteristics","PeriodicalId":31211,"journal":{"name":"Jurnal Ilmu Pertanian Indonesia","volume":"295 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140461512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chili pepper is a fruity vegetable that is often cultivated in tropical riparian wetland but is often constrained by conditions of excessive water saturation, such as shallow water tables, waterlogging and submergence in the transition period (dry to rainy season). The aim of this research was to study the morpho-agronomy of varieties of chili peppers under waterlogging stress during the early vegetative stage. A Plot Design was used in this experiment. The main plot consisted of (1) control (field capacity, regularly watering) and (2) waterlogging (simulated by adding water to the growing substrate until a thin layer of water was visible above the substrate surface during four days, followed by a seven-day recovery time during seven days). The subplot consisted of three chili pepper varieties, namely Laris, Romario, and Takanotsume (Japanese variety). Results of this study revealed that waterlogging stress significantly affected root length, number of leaves, total leaf area, chlorophyll content (SPAD), root fresh weight, shoot fresh weight, root dry weight, and shoot dry weight after stress and after recovery time. Meanwhile, chili pepper varieties were only significantly affected the total leaf area and chlorophyll content (SPAD). The total dry weight of Romario and Takanotsume before stress, after stress and after recovery did not significantly increase under waterlogging stress, whereas the total dry weight of Laris was precisely increased, indicating that vegetative growth is continuing. The Laris was categorized as one of chili pepper varieties that had medium tolerance to waterlogging stress at the early vegetative stage. \u0000 \u0000Keywords: Capsicum annum L., soil plant analyses development, total dry weight, waterlogging","PeriodicalId":31211,"journal":{"name":"Jurnal Ilmu Pertanian Indonesia","volume":"22 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140512573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This disease threatens oil palm production, especially in Southeast Asia. Trichoderma sp. fungi can control Basal Stem Rot disease in Ganoderma boninense but are ineffective. One solution that can be done to inhibit the growth of Ganoderma sp. is by using Dark Septate Endophyte (DSE) fungi. Research on DSE isolated from sugar palm (Arenga pinnata Merr.) has not been widely studied. The sugar palm plant is related to the oil palm plant in the Arecaceae family. This study aims to analyze the potential of DSE fungi from the roots of the sugar palm plant in inhibiting the pathogenic fungi Ganoderma sp. The stages of this research were isolation and purification of DSE fungi from sugar palm roots, DSE antagonists against Ganoderma sp., and DSE volatile compounds against Ganoderma sp. The results of isolation and purification showed that there were 18 DSE isolates grouped based on morphological similarities in the form of DSE fungi colony colors, where there were ten fungi isolates representing ten different colony colors, namely, isolate A.3.1 (1); A.3.2 (2); A.4.1 (2); A.4.1 (3); A.4.2; A.5.2; A.5.3; A.6.1(a); A.6.2(a); A.6.4(a).
