Abstract

Lead acetate inhaled caused oxidative damage of liver due to the formation of free radicals. Ones of the plant thathas a high antioxidant content is Usnea baileyi. This study aims to examine the potency of fresh and boiled U.baileyi to reducing rats liver damage induced by lead acetate. This study used randomized complete design withnine treatments and three replications. Twenty seven male rats were randomly divided into 9 groups namely onepositive control group (given 100 mg/kb bw lead acetate), two negative control groups (given 1 ml fresh sap and 1ml boiled sap), three groups given U. Baileyi immersion treatment in fresh sap and three group treated U.Baileyi immersion in boiled sap with dose of 3,500 mg/kg BW, 6,000 mg/kg BW and 10,500 mg/kg BW afterinduced by 100 mg/kg BW lead acetate. Treatment was given orally for 15 consecutive days The results showedthat the morphology of rats treated with U. baileyi dosages of 6,000 mg/kg bw and U. baileyi 10,500 mg/kg b wboth in fresh sap and boiled sap had morphology that was not significantly different from negative controls.Whereas in the histological structure only the dose U. baileyi 10,500 mg/kg Bw did not show a significantdifference with negative cotrol. It can be concluded that the dose of U. baileyi 10,500 mg/kg Bw rats in boiled sapgave the best effect in reducing damage to liver histology of rats induced by lead acetate.

Abstract

Tempe is a traditional Indonesian fermented food in which fungi, particularly Rhizopus spp. Durian seeds can be used as food alternative in the form of tempe that can add information about nutrition to the community and can create environmentally friendly. This study aims to find out how to process the waste of durian seed into an alternative tempe and tempe yeast concentration which produces the best tempe through the test of organoleptic properties. This study used Completely Randomized Design (RAL) with 3 (three) treatments and 3 (three) replicates, in which the treatments were given: control, 1 gram tempe yeast concentration and 2 gram. Organoleptic testing of durian seed tempeh viewed in terms of color, smell, texture, compactness, and taste. Organoleptic tests were used by hedonic test on a hedonic scale performed on 30 panelists. Research data were analyzed using ANAVA (Variance Analysis), followed by BNT test 95% level. The results showed that the tempe yeast concentration had significant effect on all organoleptic parameters. Testing of organoleptic tempe of durian seeds showed that most panelists liked the color, smell, texture, compactness and taste with 2 gram yeast concentration treatment.Keywords: Durian seed, tempe, yeast, organoleptic test.

Abstract

Neem leaves is one part of the neem tree which can be used as a traditional medicinal herb. The purpose of this study was to examine the effect of neem leaf ethanol extract on hepatosomatic index (HSI) and hepatocyte diameter in female mice. The study used a Complete Randomized Design consist of 4 treatments and 5 replications including K (aquadest), P1, P2 and P3 (neem leaf ethanol extract with dose of 8.4,11.2 and 14 mg/ kg BW/day. The treatment was administered orally with a volume of 0.2 mL for 21 days. Body weight were measured every 7 days. The liver was isolated, weighed and histologically prepared with paraffin method, HE staining and 5 μm incision thickness. HSI value determined from body weight and liver weight. Hepatocyte diameter were measured on 7 hepatocytes per lobule. The data was analyzed using ANOVA at 95% confidence level. The results showed that neem leaf ethanol extract had no significant effect (p> 0,05) on body weight, liver weight, HSI value and hepatocyte diameter, but the liver microanatomy showed hepatocyte damage. It can be concluded that exposure of neem leaf ethanol extract for 21 days still safe to be used for reference of traditional medicine. Keywords: Neem leaf, HSI, hepatocyte diameter

Abstract

The Bukit Rimbang Bukit Baling Wildlife Reserve Area (SMBRBB) Riau is one of the areas that has the characteristics of lowland rainforest types with high biodiversity, so it is possible to find many macro fungi, but there is no data on macrofungi diversity. This research was conducted with the aim of obtaining diversity data and potential data on macrofungi, both as food ingredients and as medicinal ingredients. This study uses a searching method that is modified by the path method using sample plots. 138 macrofungi species were obtained, which included 52 genera, 37 families and 3 phyla. Macrofungi diversity index at this location is relatively moderate, and high uniformity index. 66 species potentially as medicinal ingredients, including Amauroderma rugosum, Ganoderma aplanatum, Ganoderma lucidum, Lentinus sajo-caju, Lentinus squamolosus, Cymatoderma elegans, Daldinea concentrica, Microporus xantopus, M. afinitis, Pycnoporus cinnabarius, Polyporus arcularius, Rigidoporus microporus, Rigidoporus microporus, Trametes versikularis, and Xylaria longipes. As many as 32 species have potential as food ingredients, including Auricularia auricula, Auricularia delicata, Auricularia polytricha, Cookeina sulcipes, Phallus indusiatus, Lentinus sajor-caju, Lentinus squamolosus, Pleurotus ostreatus, Schizophyllum commune, Tramella fuciformis, and Volvariellavolvacea.

Abstract

Citrus is one of the horticultural commodities that has been a focus of development in 2018. Citrus is the fourth largest commodity in the percentage of Indonesia fruit production in 2014. In 2014, citrus fruit production in Indonesia was 1,785,256 tons or around 9.01% of national fruit production. Karo Regency is a citrus production center in North Sumatra, Indonesia. According to the Direktorat Jendral Hortikultura (2015) the production of citrus commodities was 173.921 tons (53,30%). In 2014, there were 3,150,060 productive citrus trees with a harvested area of ​​7,875 ha and a production of 500,243 tons in North Sumatra. One of the varieties grown by farmers in Karo Regency is Siam. High productivity of siam is certainly also influenced by seedlings, fertilization and controlling the pests. To determine this, research has been conducted on farmers in Simpang Empat and Payung Districts, Karo Regency, North Sumatra, Indonesia. To get quality Siam seeds, farmers in two research locations used Japansche citroen plants as rootstock because they were resistant to disease and drought. Fertilization of siam uses inorganic fertilizer as much as 3-4 months, while organic fertilizer as much as 10 months. The control of pests of siam citrus is done mechanically and chemically. Pests and diseases that usually attack siam are Bractocera spp, black lice, fruit borers, fungus and powdery mildew. Keywords: cultivation, seedling, fertilizer, pest, productivity, orange, Citrus nobilis

Abstract

Nurseri is a location for seedling, maintenance, selling and purchasing of various types of plants found in big cities including Jabodetabek. This study aims to reveal nurseri management in the Kranggan area to support the sustainability and development of the nurseri. This research was conducted by intensively interviewing all owners (6 persons). Kranggan Nurseri has an area of ​​100-500 m2 with the number of managers between 2-8 persons, depending on the area and the volume of plants being traded. Nurseri owners and managers apply various managements in the seedlings, maintenance, placement, and selection of plant species by considering the volume and the processing time. Many consumers purchase due to the small size, easy maintenance and seedling. Management knowledge is gained from the experience during trading or information exchange with other nurseri traders or managers. Plant placement in the nurseri is adjusted to the needs of light, habitus, aesthetics, and plant canopies. Korean banyan (Ficus compacta) is very potential to be developed in the yard because it has attractive leaf, branching, fruit and canopy characteristics but it does not require extensive land so it is believed to have good prospect to be traded with high economic value in nurseries. Keywords: Ficus compacta, nurseries, management, Bekasi
