Abstract

[APPLICATION OF TITHONIA COMPOST DOSAGE AND PGPR FLORAONE® CONCENTRATION ON THE GROWTH PERFORMANCE AND YIELD OF EGGPLANT].  Eggplant is an important horticultural crop with high nutritional value, essential for maintaining health. Increasing eggplant production can be achieved through the use of superior varieties and optimized cultivation techniques. However, much of Indonesia's agricultural land consists of marginal soils, such as Ultisol, which pose challenges to cultivation. These challenges can be mitigated by incorporating organic materials, such as Tithonia compost, and utilizing Plant Growth-Promoting Rhizobacteria (PGPR).This study aimed to evaluate the interaction effects of different doses of Tithonia compost and concentrations of PGPR FloraOne® on the growth and yield of eggplant. The experiment was conducted from February to May 2023, using a completely randomized design (CRD) with two factors and three replications. Data were analyzed using analysis of variance (ANOVA) with an F-test at a 5% significance level, followed by HSD for mean separation. The results indicated that the combination of Tithonia compost at a dose of 15 tons/ha and PGPR concentration of 45 mL/L yielded the earliest flowering time. Tithonia compost significantly influenced plant height, leaf number, flowering time, number of flowers, fruit length, fruit diameter, fruit number, and fruit weight per plant. Meanwhile, PGPR application significantly affected leaf number, flowering time, and fruit length. These findings highlight the potential of integrating Tithonia compost and PGPR to enhance eggplant growth and productivity, particularly on marginal soils.

Abstract

[EFFECT OF STORAGE METHOD ON QUALITY OF BAMBARA GROUNDNUT (Vigna subterranean L.) SEEDS]. Bambara groundnut is a legume that has potential as a food crop. Bambara groundnut seeds are usually stored in their pods. The used of pod storage can reduce storage capacity and increase seed weight on distribution. This research aims to study the effect of pods and packaging types on the viability and vigor of bambara groundmut seeds so as to obtain a safe and efficient storage method. A randomized complete design was employed, consisting of two factors. The first factor was the seed storage method (four levels): seeds with pods in PP-plastic, seeds with pods in plastic sack, seeds without pods in PP-plastic, and seeds without pods in plastic sack packaging. The second factor was storage period: 1 to 6 months. Storage was carried out in a room at 20 °C and RH 65%. The results showed that plastic packaging is absolutely necessary to maintain seed moisture content (mc) because the pods could not maintain it. Seed in plastic sack packaging had mc of 11,1% - 11,4%, while initial seed has mc of 9,0%, seed stored in PP-plastic had mc of 9,4% - 9,6%. Pod removal suppressed fungal infection. Fungal infection of seeds stored in plastic packaging without pod (17,11%) was lower than seed with pods (44,00%). Vigor of seed stored without pods in PP-plastic was better than others. Moreover, storage of bambara groundnut seeds without pods can reduce storage space requirements (64,62%) and reduce seed transportation weight (25,89%). Bambara seed should be extracted from the pod and save in PP plastic packaging in order to keep the seed vigor and efficient in storage requiirement.

Abstract

Indonesia needs to diversify cane sugar into brown sugar to reduce imports of cane sugar. Excessive consumption of cane sugar is one of the causes of the increase in diabetes mellitus sufferers. The sugar palm plant as a producer of brown sugar has the potential to be developed as a substitute for cane sugar. Identification of sugar palm plants is carried out to determine genetic diversity. High genetic diversity also has high adaptability. This research aims to determine differences in the morphological characteristics of sugar palm plants based on different altitudes and identify the level of uniformity of morphological characteristics in sugar palm plants. The results of these observations are used as initial data to determine the parent tree that will be used as propagation material. The research was conducted in North Lintau Buo District, Tanah Datar Regency, West Sumatra from September to October 2024. Sampling locations were taken based on different altitudes with three plant samples per altitude until nine plant accessions were obtained. The research results showed that the quantitative and qualitative characters of sugar palm plants had relatively narrow phenotypic variability values. The kinship analysis of sugar palm plants has a level of similarity with a coefficient value of 10.13 – 80.39%. The closest relationship distance is shown in accession 8 and accession 9, with a similarity level of 80.39%. Meanwhile, accession 4 has a distant relationship with accessions 1, 3, 2, 7, 8, 9, 6, and 5 with a similarity level of only 10.13%. PCA analysis shows that accession 4 is different from other accessions based on the characteristics of bark color, frond shape, petiole shape, and build leaflets.

Abstract

Sugar palm (Arenga pinnata), a member of the Arecaceae (Palmae) family within the Angiospermae group, is a multifunctional plant with significant economic value. Its sap serves as a primary ingredient for palm sugar production, while its young fruit is consumed as food, its fibers are utilized for roofing, and its trunk is processed into handicrafts. However, concerns have arisen regarding the plant’s declining availability due to imbalanced cultivation. A key factor contributing to the low cultivation interest among farmers is the prolonged maturation period of sugar palm. To support conservation efforts and sustainable management, morphological characterization is crucial in determining genetic relationships, which can assist breeders in preserving germplasm stability. This study aimed to assess the morphological characteristics and genetic diversity of sugar palm populations in Sikakap District, Mentawai Islands. The research was conducted from August to November 2024 using a survey method with purposive sampling. Morphological data were collected through direct observation, analyzed descriptively, and similarity relationships were determined using NTSYS Ver. 2.10 software. The exploration identified 15 accessions categorized into two groups, with genetic similarity levels ranging from 27% to 50%. A similarity coefficient of 27% indicates significant morphological variation among the observed accessions, particularly in plant height, sheath length, stem circumference, number of leaflets, leaflet width, leaflet length, and fruit diameter. The accession Pagai Selatan (PS2) exhibited the greatest morphological divergence. These findings provide valuable insights for conservation strategies and selective breeding programs aimed at maintaining the genetic diversity and sustainability of sugar palm populations.

Abstract

[[INFESTATION LEVEL OF GREEN SCALE INSECT (Coccus viridis) ON COFFEE PLANTS AT PT PTL COFFEE BEAN, SOLOK SELATAN REGENCY]. The green scale insect (Coccus viridis) is a major pest in coffee plantations in Indonesia. It is classified as an economically significant pest due to its potential to cause up to 50% plant damage, leading to substantial yield reduction and financial losses. This study aims to determine the infestation level of Coccus viridis at PT PTL Coffee Bean, Solok Selatan Regency, and to analyze the influence of environmental factors on infestation intensity. The findings of this study are expected to serve as a foundation for developing appropriate pest control strategies based on the principles of Integrated Pest Management (IPM). The research was conducted using a systematic sampling method with a diagonal line pattern across the coffee plantation owned by PT PTL Coffee Bean. Direct field observations were performed, and further analyses were conducted at the Integrated Pest Management Laboratory, Faculty of Agriculture, Andalas University. The results showed that the infestation intensity of Coccus viridis on coffee plants at the study site was 15.38%, which falls into the mild infestation category. The infestation level was influenced by environmental factors such as altitude, temperature, humidity, light intensity, and cultivation techniques. Although the infestation level was classified as mild, regular monitoring remains essential to prevent an increase in pest populations. Furthermore, IPM-based control strategies should be optimized to sustain coffee plant productivity, including the conservation of natural enemies and the application of proper cultivation techniques.

Abstract

[SEED GERMINATION AND FLAVONOID CONTENT OF SORGHUM EXTRACTS UNDER DIFFERENT LEVELS OF DROUGHT STRESS]. Weeds are one of the major challenges in agricultural cultivation systems, as they can reduce crop productivity. One strategy to enhance the production of secondary metabolites in sorghum plants is the application of abiotic stress, such as drought. This approach not only has the potential to produce high-quality extracts but also supports the development of effective bioherbicides. This study aims to analyze the effects of drought stress on flavonoid content and the allelopathic properties of sorghum. The research was conducted from June to August 2024 in the Greenhouse of Bengkulu University, with bioassay tests performed in Pematang Gubernur, Muara Bangkahulu, Bengkulu City. The study employed a single-factor completely randomized design (CRD) using two sorghum varieties, Super 1 and Suri 4. The drought stress treatments included three levels of watering frequency: daily, once every three days, and once every five days. The bioassay was conducted using the petri dish method, where each petri dish was treated with 10 mL of sorghum aqueous extract, 25 mung bean seeds were sown, and incubation was carried out for three days. The results showed that the highest total flavonoid content was found in the Super 1 variety with watering every five days (4067.01 µg/g), while the lowest was observed in the Suri 4 variety with daily watering (2948.07 µg/g). The highest seed germination inhibition was recorded in both Suri 4 and Super 1 varieties under the five-day watering interval. These findings indicate that the Super 1 and Suri 4 sorghum varieties subjected to drought stress can serve as potential bioherbicide sources for sustainable weed management.

Abstract

[TERMITE DIVERSITY IN TEAK IN TULUNGAGUNG AND WONOGIRI REGENCIES]. Termites are insects that have a very high potential for damage to various stands such as teak. This study aimed to identify the diversity of termite species in teak stands in Tulungagung and Wonogiri regencies. Sampling using the transect method with a transect area of 10 m x 60 m and feeding with pine wood placed in five sub-districts in Tulungagung Regency (Kalidawir, Pucanglaban, Tanggunggunung, Campur Darat, and Ngunut) and five sub-districts in Wonogiri (Jatiroto, Jatisrono, Sidoharjo, Slogohimo, and Purwantoro). The results showed that at least four termite species were found, Macrotermes gilvus, Odontotermes sp., Microtermes insperatus, and  Nasutitermes havilandi. Termite diversity in Wonogiri was classified as medium with the highest H’ value (1.08), while termite diversity in Tulungagung was low with the lowest H’ (0.59). The dominance value of termite species in both districts was classified as medium and the evenness value in all observation locations showed an average high evenness index value. The results of the non-metric multidimensional scalling analysis showed that Jatiroto Subdistrict and Ngunut Subdistrict have a high level of species similarity (0.90).

Abstract

[THE EFFECT OF VARIOUS SOIL AMELIORANTS AND MICRONUTRIENT FERTILIZER CONCENTRATIONS ON EDAMAME (Glycine max (L.) Merill) PLANTS IN PEAT SOIL]. The cultivation of edamame (Glycine max (L.) Merrill) in Indonesia remains limited, despite increasing demand in both domestic and export markets. However, peat soils present challenges for edamame production due to their high acidity and nutrient deficiencies. This study aimed to evaluate the effects of different soil amendments and micronutrient fertilizer concentrations on the growth and yield of edamame cultivated in peat soil. The research was conducted from March to May 2023 at the Agribusiness Technical Implementation Unit (UPT) of the Pontianak City Agriculture and Food Security Office. A factorial completely randomized design (CRD) was employed, with the first factor being the type of soil amendment (chicken manure, cow manure, and oil palm bunch compost) and the second factor being micronutrient fertilizer concentrations (0 g/L as control, 0.100 g/L, 0.125 g/L, 0.150 g/L, and 0.175 g/L). Results indicated that the interaction between soil amendments and micronutrient fertilizer concentrations had no significant effect on all measured variables. Soil amendments alone had a significant effect on plant height at two and three weeks after planting, but not at four weeks, nor on branch number or plant dry weight. Conversely, micronutrient fertilizer concentration significantly influenced plant dry weight only. These findings suggest that while soil amendments support early vegetative growth, micronutrient fertilizers primarily enhance biomass accumulation. The study provides practical insights for optimizing fertilization strategies to improve edamame cultivation on peat soils.

Abstract

Generative propagation of Mucuna bracteata is complicated and requires special treatment to germinate. Mucuna has a thick, rigid, and impermeable seed coat, which becomes a mechanical barrier to water or gas entry, making the imbibition process challenging to occur. Breaking dormancy in mucuna seeds aims to increase germination. This study aims to determine the effect of soaking time for mucuna seeds (Mucuna bracteata) at different water temperatures on breaking dormancy. This study used a completely randomized design factorial. This study consists of 2 treatment factors. The first factor is the length of soaking (L), which consists of 3 levels: 30 minutes, 60 minutes and 90 minutes. The second factor is water temperature (K), which consists of 3 levels: 30 °C, 60 °C and 90 °C. Data analysis used variance analysis and simple regression analysis. The results of the study showed that water temperature had a significant effect on increasing germination power, accelerating germination, increasing the number of normal sprouts, and the dry weight of mucuna (Mucuna bracteata) sprouts..

Abstract

[THE EFFECT OF NATURAL BOOSTERS ON THE GROWTH OF TUBERS OF Amorphophallus paeoniifolius (Dennst.) Nicolson.  Amorphophallus paeoniifolius is a plant with high economic value in the food sector due to its glucomannan content of approximately 20%, which plays a role in lowering blood sugar and cholesterol levels. Its tubers are also rich in resistant starch and glucomannan fiber, offering potential for development as a postbiotic. Additionally, this plant is utilized in the food and cosmetic industries and exhibits antibacterial and antifungal properties. However, its cultivation remains limited, primarily due to a lack of information regarding its benefits and propagation techniques. This study aims to analyze the effect of natural growth boosters on the tuber growth of A. paeoniifolius in the conservation area of the Science Education Study Program, Faculty of Teacher Training and Education, University of Bengkulu. The research employed a descriptive method using stem tuber propagation techniques with four treatments: shallot extract, bamboo shoot extract, control (no booster), and Rootone-F, each with six replications. Observed variables included stem height, stem diameter, and the number of shoots over a 10-week period (August–October 2024). The results showed that the shallot treatment yielded the highest growth rate at 66% (4 samples sprouted), followed by Rootone-F at 50% (3 samples), while the control and bamboo shoot treatments each resulted in 16.6% (1 sample). Shallot extract also demonstrated superior efficacy in stimulating the emergence of multiple shoots per tuber. The environmental conditions during the study were optimal, with temperatures of 27.8–32.3 °C, humidity levels of 56.5–77%, and soil pH ranging from 6.15 to 6.5. In conclusion, natural growth boosters, particularly shallot extract, positively influence the tuber growth of A. paeoniifoliu
