Abstract

A red chili plant (Capsicum spp.) is one of the horticultural commodities in Indonesia which has good economic value, so it has priority to be developed. Agriculture practices in Java island have partly switched to coastal areas which have characteristics of saline soils. Saline soils are alkaline and nutrient-poor, especially essential nutrients such as P and N. One way to restore fertility in saline soils used beneficial and fertilizing bacteria such as PGPR. Plant growth-promoting rhizobacteria (PGPR) are free-living, soil-borne bacteria, which are capable of enhancing the growth of the plant either directly or indirectly. The objectives of this research were to determain the effect of PGPR isolates to the growth of red chili plants in saline sandy soil and to determine the best PGPR isolate capable to improve the growth of red chili plant in saline sandy soil. The result showed that the inoculation of rhizobacteria significantly affected to plant height and root length of the red chili plant (Capsicum annum). The combination of 3 PGPR isolates (Azospirillum PSA 10, Azotobacter PSA 8, and Marinococcus PSA 1) was the best result in increasing the height and root length of the chili plant (Capsicum annum).

Abstract

Endophytic bacteria are bacteria that live in plant tissues and are not pathogenic to the host. One of endophytic bacterial host is water hyacinth. Water hyacinth could accumulate heavy metals, one of which is chrome. The purpose of this study was to obtain endophytic bacteria of water hyacinth (Eichhornia crassipes Mart.), to identify the endophytic bacteria of water hyacinth, and to determine the resistance of endophytic bacteria of water hyacinth to Chrome (Cr). The research method used was a survey with a purposive random sampling technique. Stages of research include root sampling, sterilization of root samples using 2% NaOCl3, isolation of water hyacinth endophytic bacteria on agar nutrient medium (NA), characterization of bacterial endophytes and resistance test of water hyacinth bacteria to chromium. Based on the results of the study, 8 isolates of endophytic bacteria were isolated from the roots of water hyacinth. Based on Bergey's Manual Determinative of Bacteriology, 6 bacterial isolates (E1, E2, E3, E5, E6, E8) were identified as Bacillus and 2 isolates (E4, E7) were identified as Pseudomonas. All water hyacinth endophytic bacteria obtained were resistant to chromium to a concentration of 750 mg/L.

Abstract

Nilem fish belongs to freshwater fish commodity that has been widely cultivation. Some factors influencing fish cultivation are good quality of feed, quantity, size, and shape. Quality feed works as a primary energy source as well as improves the digestive system of fish, with the expectation that the fish growth and health are optimal. Information concerning health status in cultivation Nilem has been used as a reference for improving cultivation methods and controlling disease attacks. The population and production of fish cultivation is experiencing serious problems due to infection from various types of pathogens. Therefore, a viable alternative is needed to prevent and overcome diseases by utilizing immunostimulant substances derived from synthetic substances that can increase the activity of non-specific immune defenses and stimulate antibiotic-forming organs in fish body. Immunostimulant is a substance that is capable of increasing the mechanism of non-specific immune response of fish one of them is by adding Chlorella vulgaris extract to the feed. This research objective is to determine the influence of Chlorella vulgaris supplementation on total blood albumin in nilem fish. This research was conducted by sampling method consisting of 5 treatments with further 4 replications. The treatments were feed supplementation of 0 g.kg-1, 2 g.kg-1, 3 g.kg-1, 4 g.kg-1, and 6 g.kg-1. Independent and dependent variables were used in this research; the independent variable was the dose of Chlorella vulgaris in the feed and the dependent variable was blood albumin concentration. The measuring of plasma albumin concentration was done using the Dyasis kit method with a spectrophotometer. The obtained data were then analyzed by ANOVA, followed by the Least Significant Difference (LSD) at the 95% confidence level if there is a real difference then followed by Tukey's test at the same confidence level. The results showed that the average value of serum albumin concentration of nilem fish from all treatments was between 4.2761 – 7.1826 g/dL. The normal albumin concentration was found in the treatment 4 g.kg-1 Chlorella vulgaris supplementation which was 4.77 g/dL. Meanwhile, the highest concentration was found from the supplementation of Chlorella vulgaris at 3 g.kg-1 feed which was 6.677 g/dL.

Abstract

Mentimun (Cucumis sativus L.) dan Melon (Cucumis melo L.) merupakan contoh dari sayuran dan buah yang banyak di konsumsi oleh masyarakat, serta juga memiliki banyak manfaat. Permintaan pasar untuk mentimun dan melon sangat tinggi, maka produksi harus mengikuti tingginya permintaan pasar. Ada beberapa permasalahan dalam produksi, salah satunya adalah penyakit layu yang disebabkan oleh Fusarium. Secara konvensional, penggunaan fungisida sintetik dianggap sebagai solusi yang tepat untuk mengendalikan penyakit layu fusarium. Namun demikian, dengan mempertimbangkan dampak negatif dari fungisida tersebut, penggunaan Fungi Mikoriza Arbuskula (FMA) menjadi alternatif pilihan yang dapat diaplikasikan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan dosis berbeda dari inokulum FMA campuran (0, 5, 10, 15, 20 g FMA dengan medium pembawa zeolit / tanaman). Parameter utama adalah intensitas penyakit, sedangkan parameter pendukungnya adalah pH tanah, temperatur, kelembapan, masa inkubasi penyakit, dan derajat infeksi FMA terhadap akar tanaman. Data yang diperoleh dianalisis dengan menggunakan Uji ragam (uji F) denganStandar Kesalahan 5%. Berdasarkan hasil penelitian, tanaman yang diinokulasi dengan inokulum mikoriza lebih tahan terhadap penyakit layu fusarium. Dosis optimal FMA campuran untuk mengurangi intensitas penyakit layu fusarium pada tanaman mentimun adalah adalah M3BT (inokulasi FMA campuran 15 g/tanaman) dan melon adalah M2BM (inokulasi FMA campuran 10 g/tanaman)

Abstract

Lizard or known as the Asian water lizard (Varanus salvator) is one of the reptiles found in Asia, one of which is in Indonesia. In addition to being used as food, some communities use monitor lizards to treat diseases, especially those who still maintain ancestral customs and beliefs. This study aims to describe the knowledge of local indigenous peoples in utilizing monitor lizards for the treatment of diseases and integrating them with traditional conservation efforts undertaken by the community. The research uses the ethnozoology approach through the literature review method. The results showed that the local people especially Suku Anak Dalam (SAD) in Jambi used monitor lizards for the treatment of skin diseases, hypo-allergies and ringworm by burning or cooking them using cooking oil until the fat in the monitor lizards melted for ointment. However, the local people still try to maintain the balance of monitor lizards by choosing large monitor lizards that are suitable for consumption, using simple hunting tools, and domestication efforts so that the monitor lizard population is maintained in a sustainable manner. This is known because the mechanism of hypo-allergenic treatment of monitor lizard meat has the potential to reduce the effects of allergies given by allergy in the form of histamine 1.5% by 10 ml. In conclusion, the use of monitor lizards in the field of health by the local community wisely can improve conservation skills through traditional ecological knowledge (Traditional Ecological Knowledge)

Abstract

The waters of Karangtengah Nusakambangan Cilacap have various types of substrates, namely sand, coral and mixture. Beach conditions with many types of substrates allow various species of seaweed to grow. Information regarding the diversity and dominance of seaweed producing hydrocolloid species has not been much studied in the waters of Karangtengah Beach. This study aims to determine the diversity and dominance of seaweed producing hydrocolloids on different substrates in the waters of Karangtengah Nusakambangan Cilacap. This study uses a survey method with a sampling technique that is the selected random transect method. Six transect lines were made perpendicular to the coastline and the distance between transects was 25 m. Each transect was made three plots, each plot measuring 1x1 m based on the substrate (coral, sand, and mixture). The main parameters observed were the amount of biomass and the number of species. Supporting parameters observed were environmental factors namely temperature, salinity, pH, current speed and depth. The number of hydrocolloid seaweed species found was 10 species of seaweed with details of 5 alginate-producing species, 3 agar-producing species, and 2 carrageenan-producing species. The diversity index value in the coastal waters of Karangtengah between 0,6-2,0 was classified as moderate diversity. The dominance index value in the coastal waters of Karangtengah between 0,2-0,6 was classified as low dominance.
