Kapang tersebut dapat menginfeksi dengan cara penembusan hifa ke tubuh serangga inang melalui kulit, saluran pencernaan, spirakel dan lubang lainnya. Tujuan dari penelitian ini yaitu untuk mengisolasi dan mengidentifkasi kapang entomopatogen pada tanah serasah daun jati dan tanah sawah dengan metode isolasi yang berbeda. Metode isolasi kapang entomopatogen menggunakan metode insect bait, insect bait dengan pengayakan tanah, dan metode pengenceran. Serangga yang digunakan untuk uji larva Tenebrio molitor.  Isolasi tanah sawah berhasil menumbuhkan kapang entomopatogen pada tubuh larva Tenebrio molitor ditandai dengan adanya miselium kapang menutupi tubuh larva. Hasil isolasi didapatkan 6 isolat yaitu  S2A, S2B, S2C, S3A, S3B, S3C. Keenam isolat tersebut merupakan kapang Fusarium sp.   Kata kunci: Fusarium sp., identifikasi, isolasi, kapang Entomopatogen, T. molitor Entomopathogenic fungi are molds that have the ability to infect insects. The mold can infect by penetrating the hyphae into the host insect's body through the skin, digestive tract, spiracles, and other holes. The purpose of this study was to isolat and identified entomopathogenic molds in teak leaf litter and paddy fields with different isolation methods. The isolation method of entomopathogenic molds used the insect bait method, insect bait with soil sieving, and the dilution method—insects used for the larval test of Tenebrio molitor. Isolation of paddy fields succeeded in growing entomopathogenic molds on the larval body of Tenebrio molitor, which was indicated by the presence of mold mycelium covering the larval body. The isolation results obtained 6 isolats, namely S2A, S2B, S2C, S3A, S3B, S3C. The six isolats were Fusarium sp.   Keywords: Entomopathogenic fungi, Fusarium sp., Identification, Isolation, T. molitor

Abstract

Large ruminants, consisting of cattle and buffalo, have played an important role in human life from the past to the present. Information about the utilization of large ruminants was often found in inscriptions in ancient Java. Unfortunately, the diversity of these large ruminants was not described in detail. The reliefs of the temples can be used as a consideration in understanding the diversity of large ruminants based on the morphological characteristics carved in the reliefs. Borobudur Temple, a historical building from the 8th century AD which was rich in reliefs, can be used as a data source to find information about the diversity of the large ruminants in Java. The aims of this study was to find the diversity of the large ruminants in Java in the 8th century based on the reliefs at Borobudur Temple. The research was conducted by observing various large ruminant images contained in the reliefs of Borobudur Temple. The results of the observations were interpreted and clustered based on their morphological characteristics. The results showed that there were ten relief panels containing images of cattle and nine relief panels containing images of buffalo. Based on the observed morphological characteristics, it could be concluded that there was only one breed of cattle and buffalo, respectively zebu (Bos indicus) and wild buffalo (Bubalus arnee).

Abstract

Strawberry (Fragaria sp.) is a horticultural plant originating from the Americas. Strawberries have a distinctive sweet and refreshing taste, and contain lots of vitamins and antioxidants that are useful for body health. But strawberries are also easily damaged. This damage can be caused by spoilage microorganisms such as bacteria and fungi that can grow if conditions permit such as the presence of appropriate temperature and humidity conditions. In this experiment, aims to isolate pathogenic microorganisms that cause disease in symptomatic strawberries and prove that these pathogens actually cause disease using Koch's Postulates method and then descriptive analysis is carried out. From the experimental results, it was found that soft rot disease in strawberries was characterized by rotten fruit parts that looked wet, slightly brownish in color, slimy, there were fine white threads and emitted a foul odor with a percentage of IP (disease occurrence) of 100% and KP (disease severity) of 92.66% where based on the score the damage was the highest.

Abstract

Eggplant (Solanum melongena L.) is an authentic plant native to tropical climates, widely favored by the community, and available at an affordable price. The demand for eggplant in Indonesia reached 69,963 tons in 2015 and has continued to increase to 74,081 tons. Based on FAO data in 2016, Indonesia is one of the eggplant-producing countries, ranking sixth in the world after China, India, Egypt, and Turkey. The Laguna F1 eggplant variety is known for its quality and resistance to bacteria-causing wilting. To minimize the cultivation time of eggplants, it is necessary to use readily available natural fertilizers, one of which is coconut water. The utilization of coconut water as fertilizer is due to its content of various hormones that play a crucial role in plant growth, namely auxin, cytokinin, and gibberellin. The purpose of this research is to investigate the effects of coconut water and atonic, determine the optimum concentrations, and understand the interaction between coconut water and atonic in the growth of eggplant plants. The research was conducted in the Botany Laboratory of the Department of Biology, Faculty of Mathematics and Natural Sciences, Universitas Lampung, in October-November 2019, using a 2x3 factorial design. The first factor involved coconut water at concentration levels of 25%, and 50%, and compared with a control group (0%). The second factor was the atonic solution with a concentration of 10 ml/l, compared with a control. The treatments were repeated in five replications, resulting in 30 experimental units. Observed variables included plant height, fresh weight, dry weight, relative water content, and chlorophyll content. The results of this research can be summarized as follows: the application of coconut water and atonic has a positive effect on the growth of eggplant plants. Additionally, the combined induction of coconut water at a concentration level of 25% and atonic at 0% demonstrated superior outcomes in terms of plant height, fresh weight, dry weight, relative water content, and chlorophyll content in eggplant plants.

Abstract

Hyperglycemia is an early symptom of diabetes caused by the pancreas not being able to produce enough insulin. This condition can disrupt blood glucose metabolism, thereby damaging organs in the body such as the pancreas. Hyperglycemia can be treated using traditional plant medicines. Songgo Langit leaves (Tridax procumbens L.) are reported to have secondary metabolite compounds that have potential as antidiabetic drugs. This study aims to determine the effect of administering Songgo Langit leaf extract on blood glucose levels and changes in the histopathological structure of the pancreas in hyperglycemic mice induced by alloxan. Using Complete Random Design, mice were divided into 5 groups of 5 mice each. Group K (-) was a negative control (not treated), group K (+) was a positive control (only induced by alloxan), group P1 was induced by alloxan and extract of 0.45 mg/g BW, group P2 was induced by alloxan and extract 0.9 mg /g BW, and group P3 was induced by alloxan and extract 1.8 mg/g BW for 14 days. Glucose level data were analyzed using ANOVA and post hoc test with LSD. Pancreatic histopathological structure data were analyzed using the Kruskal-Wallis test and the Mann-Whitney post hoc test. The results showed that the treatment of ethanol extract of Songgo Langit leaf at doses P1, P2, and P3 were significantly able to reduce blood glucose levels by 61.70%, 65.11%, and 74.79% and was able to repair damage to pancreatic histopathology of mice induced by alloxan.

Abstract

Catfish (Clarias gariepinus) is a fish that is cultivated for human consumption. The success rate of cultivation is influenced by many factors, including the presence or absence of parasitic infections in cultivated fish. This study aims to determine the type, prevalence, and level of ectoparasite attacks on Dumbo Catfish in the Rajabasa Raya fishing pond, Bandar Lampung. The ectoparasites were taken using the method of scraping mucus and staining the ectoparasites on the surface of the fish's body, and then identified. The prevalence rate is determined using the Kabata prevalence formula. The results showed that two types of ectoparasites were found, namely Dactylogyrus sp. with the highest prevalence of 100% (infection rate is always), and Gyrodactylus sp. with the highest prevalence of 80%. (infection rate is common).
