Abstract

This study aims to determine the effect of biofertilizer fermentation duration on the stem length growth of water spinach (Ipomoea reptans) in a hydroponic system. The biofertilizer was fermented for 7, 14, and 21 days, then combined with AB mix nutrient solution in various concentrations. The experimental design used was a Randomized Block Design (RBD) with five treatments: 100% AB mix control, biofertilizer combined with 75%, 50%, and 25% AB mix, and biofertilizer without AB mix, with three replicates for each fermentation duration. The parameter observed was the stem length of water spinach plants after five weeks of cultivation. The results showed that the biofertilizer from the 21-day fermentation had the most significant effect on stem length increase, particularly in combination with 50-75% AB mix. Meanwhile, the use of biofertilizer without AB mix resulted in shorter stem lengths. Thus, the biofertilizer from the 21-day fermentation process has potential as a nutritional supplement in hydroponic systems, but it cannot fully replace the role of AB mix.

Abstract

ABSTRACTThis study aims to summarize research findings on the genetic inheritance patterns of chili pepper (Capsicum sp.) through a Systematic Literature Review (SLR). The need for this study arises from the limited integration between phenotypic and molecular analyses in Indonesian research, although both approaches are essential for supporting effective breeding programs. The review followed the PRISMA 2020 guidelines and used Publish or Perish to search relevant articles in Google Scholar published between 2015-2025. A total of 136 articles were identified, and after screening for duplication, relevance, and quality, 12 studies were selected for analysis. The results show that qualitative traits in chili peppers, such as fruit color and morphological characteristics, are generally controlled by one or two major genes and follow Mendelian patterns. Meanwhile, quantitative traits such as fruit weight, yield, and size tend to be polygenic with moderate to high heritability values. Molecular approaches, such as the use of SSR markers, have also been applied to identify traits related to disease resistance. These findings highlight the importance of combining phenotypic and molecular data to optimize selection strategies and support the development of superior chili varieties in tropical environments.Keywords: Breeding, Capsicum Sp., Genetics, Heritability, Inheritance

Abstract

Artocarpus integer (cempedak) is a tropical plant widely used in South Kalimantan, known for its rich bioactive compounds, which make it a promising source for drug discovery through in silico approaches. This study aims to identify and predict the potential of bioactive compounds from A. integer as drug candidates through an in silico approach. The data were obtained from the KNApSAcK database and analyzed using the SwissADME, SwissTargetPrediction, PASS Online, and GUSAR platforms to evaluate pharmacokinetic suitability, biological targets, pharmacological activities, and predictive toxicity. Four compounds were identified, namely Integrin, Oxyisocyclointegrin, Cyclointegrin, and Artoindonesianin F. The analysis revealed that the first three compounds comply with Lipinski's Rule of Five, indicating favorable metabolic properties. In contrast, Artoindonesianin F does not meet these criteria due to its high lipophilicity. Molecular target prediction suggested that the active compounds interact with enzyme groups such as proteases, kinases, and phosphodiesterases, which play crucial roles in the therapeutic mechanisms of various degenerative diseases and cancers. Based on PASS Online analysis, Oxyisocyclointegrin and Cyclointegrin exhibited high probabilities of biological activity (Pa > 0.9), including cell membrane stabilization, enhancement of TP53 gene expression, and inhibition of cytochrome P450 enzymes. Toxicity analysis using GUSAR indicated that both compounds possess low toxicity levels, with oral LD₅₀ values of 1437 mg/kg and 1164 mg/kg, respectively. Therefore, Oxyisocyclointegrin and Cyclointegrin show promising potential as natural bioactive compound candidates for further development in natural product-based pharmacotherapy research.

Abstract

Water pollution in Lampung mostly caused by domestic waste. The proposed solution in dealing with these problems is the use of silver nanoparticles (AgNP) as a potential bioremediation agent with water hyacinth. The use water hyacinth in AgNP synthesis can help reduce weed populations and domestic waste contaminants in water that causes eutrophication. The AgNP synthesis process begins with the preparation of water hyacinth which is extracted and filtered using Whatman No. 42. The filtrate is then reacted with 2 mM AgNO3 solution and analyzed with FT-IR and SEM. After AgNP were formed, effectiveness was tested on polluted water with AgNP concentration variations of 1:1, 1:2, 1:3 and 1:4. The effectiveness of AgNP was assessed through pH, BOD5 and TSS. The result of the analysis showed that the higher the concentration of AgNP, the higher decrease in BOD5 and TSS value, as well as the improvement in pH values. These test results were supported by ANOVA analysis which showed a significant effect of AgNP concentration on pH, BOD5 and TSS.

Abstract

White turmeric (Curcuma zedoaria) is one of the strategic bio-pharmaceutical plants commonly used as a cooking ingredient and as a family medicinal plant. In the Lampung region, turmeric ranks among the top five highest-yielding bio-pharmaceutical crops, making it an abundantly available commodity. This research aims to explore the endophytic bacteria present in turmeric and to investigate the functional abilities of the isolated strains. Endophytic bacteria are microorganisms that inhabit plant tissues and can act as plant growth promoters. In addition, these bacteria can solubilize phosphate, thereby supporting plant growth. Endophytic bacteria also produce the phytohormone IAA, which plays an important role in plant development. This study obtained three endophytic bacterial isolates from the leaves of white turmeric plants, namely KPD1, KPD2, and KPD3. Isolates KPD2 and KPD3 exhibited phosphate-solubilizing activity, as indicated by the formation of clear zones measuring 2.5 ± 0.58 mm and 4.0 ± 0.82 mm, respectively. In addition, all isolates were able to produce indole-3-acetic acid (IAA), with concentrations of 54.98 µg/mL (KPD2), 54.14 µg/mL (KPD3), and 25.05 µg/mL (KPD1). The abilities demonstrated by these endophytic bacterial isolates indicate their potential as plant growth-promoting bacteria (PGPB).

Abstract

This study on the Identification of Banana Varieties in the Jambi Luar Kota District aims to classify four types of bananas found-Ambon Banana, Lemak Manis Banana, Kepok Banana, and Sarawak Banana-based on morphological characters and genetic relationships using MEGA 12 software. The results of the phylogenetic analysis divided these varieties into two main groups originating from the genus Musa.The nucleotide sequences of the target gene from several banana cultivars were downloaded from the NCBI GenBank database using the following accession numbers: MT227509.1 (Musa acuminata Ambon matk), MZ318122.1 (Musa acuminata Pisang Lilin matk), FJ871652.1 (Musa paradisiaca Kepok matk), and MZ318108.1 (Musa acuminata Serawak matk). The robustness of the generated phylogenetic tree was evaluated through 1,000 bootstrap replications to assess the confidence level of each branch. The final tree topology was then interpreted to determine the genetic relationships among the analyzed banana cultivars.

Abstract

Bread is a widely consumed food product that is highly susceptible to fungal contamination due to its high moisture and carbohydrate content. Fungal growth on bread can cause deterioration in quality and may pose health risks through the production of mycotoxins. This study aimed to identify and characterize fungi contaminating bread sold around the Poltekkes Kesuma Bangsa campus based on macroscopic and microscopic observations. This research employed a descriptive method and was conducted at the Chemistry Laboratory of Poltekkes Kesuma Bangsa on December 10, 2025. Bread samples were collected using purposive sampling and examined for fungal contamination through macroscopic observation of colony characteristics and microscopic identification using lactophenol cotton blue staining. The results showed that two types of fungi were identified, namely Aspergillus sp. and Penicillium sp. Aspergillus sp. was characterized by white to greenish colonies with a cotton-like surface and spherical vesicles microscopically, while Penicillium sp. exhibited white colonies with granular and slimy surfaces and brush-like conidiophores. One bread sample showed no fungal growth, possibly due to airtight packaging and preservative content. These findings indicate that bread sold around the campus may be contaminated by potentially harmful fungi, highlighting the importance of proper storage and food safety awareness among consumers.

Abstract

This research was conducted to determine the physical characteristics of paper made from a mixture of pineapple leaf fiber and thorny pandan leaf fiber as an environmentally friendly alternative raw material. The research method employed was an experimental design with variations in material composition, specifically 8:2, 6:4, 4:6, dan 2:8, which represent the ratio of pineapple leaf fiber to thorny pandan leaf fiber. The papermaking process began with cooking using a sodium hydroxide (NaOH) solution at concentrations of 8%, 10%, and 13% at a temperature of 100 °C. Subsequently, a bleaching stage was performed using kaolin clay (5%) dissolved in 100 mL of distilled water, which was then mixed evenly using a blender. The resulting pulp was filtered, dried, and formed into paper sheets. The research findings indicate that the highest cellulose content, measuring 99,33%, was obtained at the 2:8 composition, while the lowest content, measuring 60%, was found at the 6:4 composition. The maximum grammage reached 117 g/m² and the maximum thickness was 1,21 mm, obtained from the 2:8 and 8:2 compositions, respectively. Meanwhile, the highest tensile strength value, recorded at 4,200823 kN/m was observed in the 8:2 composition. Based on these results, the paper produced demonstrates the potential to comply with the requirements stipulated in SNI 8218:2015.

Abstract

The Sumatran elephant (Elephas maximus sumatranus), classified as Critically Endangered, plays a vital role in maintaining tropical forest ecosystems. However, habitat degradation, fragmentation, and land conversion have escalated human and elephant conflicts in Sumatra. These conflicts cause severe economic losses, crop destruction, and over 200 elephant deaths between 2010 and 2023, mainly from poaching and retaliation. This review aims to examine mitigation strategies implemented in Bukit Barisan Selatan, Way Kambas, and Gunung Leuser National Parks, and to assess their effectiveness and sustainability. Using a literature review method, relevant scientific publications on elephant conflict mitigation were systematically analyzed. Findings indicate that combined structural and non-structural approaches such as sound deterrents, elephant trenches, tame elephant patrols, and community-based units (CRU and ERU) effectively reduce short-term conflicts. Long-term success, however, requires integrated, ecosystem-based strategies emphasizing habitat restoration, corridor connectivity, and adaptive land-use planning. This study highlights the need for humanistic and sustainable mitigation to foster coexistence between humans and Sumatran elephants.
