2024-05-31T14:42:42+00:00

Bird diversity in an area is one of the guidelines in the management of biological resources. Birds play an important role in controlling insect populations, helping with pollination and seed dispersal. This study aims to identify the types of birds in the order Coraciiformes and identify their level of diversity in the CRU Sampoiniet forest area, Aceh Jaya. The method used in this study is the Point Count method with 10 observation points for each point. Then it is calculated with a duration of 15 minutes with a radius of 50 meters and a distance of 200 meters for each point. Data analysis used a bird species identification book and used the Shannon Winner diversity formula Ĥ = ∑ Pi Ln Pi. The results of the research on the diversity of species of aves the order Coraciiformes in the CRU (Conservation Response Unit) Forest Area of Sampoiniet Aceh Jaya, consisted of 7 species from 3 families with a total of 33 individuals. The overall diversity index of species of aves of the order Coraciiformes Ĥ=1,89218, so the species diversity of aves of the order Coraciiformes in the Sampoiniet Aceh Jaya CRU (Conservation Response Unit) Forest Area categorized in the low diversity index.

PENGARUH EKSTRAK KULIT PISANG AMBON (Musa paradisiaca var. sapientum (L.) Kunt) DAN EKSTRAK TAUGE (Flammulina velutipes) PADA KERAGAAN PLANLET KENTANG GRANOLA (Solanum tuberosum L.) PADA KULTUR IN VITRO

This study aims to determine the effect of Ambon banana peel extract (Musa Paradisiaca var. sapientum (L.) Kunt) and bean sprout extract (Flammulina velutipes) on the growth of granola potato (Solanum tuberosum L.) in vitro. This research was conducted in July-September 2023 at the G10 Agro Tech Medan tissue culture laboratory. In this study, potato plants were grown on Murashige and Skoog (MS) media combined with Ambon banana peel extract and bean sprout extract, using a completely randomized design (CRD) research design, with four treatments and three replicates with a concentration consisting of 4 levels, namely Ambon banana peel extract 0 g/l, 20 g/l, 40 g/l and 60 g/l and bean sprout extract, namely 0 g/l, 20 g/l, 40 g/l and 60 g/l. The observation parameters in this study were the number of roots, number of shoots, number of leaves and plant height. The data obtained were analyzed using Analysis of variance (ANOVA) and on different treatments, Duncan's multiple range test (DMRT) was conducted. The results of the analysis after the 4th observation week after planting (WAP) showed that the treatment of the addition of Ambon banana peel extract and bean sprouts had a significant effect on the number of roots, number of shoots, number of leaves and plant height. The best number of roots was produced by the combination of KP60T40 (60 g/l Ambon banana peel extract + 40 g/l bean sprouts extract) which was 10 root fibers. The number of shoots produced by KP60T20 (60 g/l Ambon banana peel extract + 20 g/l bean sprout extract) is 15.67 shoots. The highest number of leaves is KP20T20 (Ambon banana peel extract 20 g/l + bean sprout extract 20 g/l) which is 14 leaves and the treatment combination on plant height is produced by KP20T60 which is 13.67 cm. So it can be concluded that organic media of Ambon banana peel and bean sprouts can be used as alternative media because it gives a real influence on the growth of granola potatoes in vitro.

LITERATUR REVIEW : ANALISIS TINGKAT PENCEMARAN UDARA AKIBAT LALU LINTAS KENDARAAN DI INDONESIA

Human activities can directly or indirectly cause air quality to drop to a certain level. The increasing growth of a city goes hand in hand with increasing human activities and the increasing number of vehicles in urban areas, resulting in changes in the composition of ambient air quality. The decrease in air quality can disturb and endanger the surrounding environment, especially humans. This research was conducted with a literature study related to air pollution due to transportation activities in regencies and cities in Indonesia. Based on the results of the literature study, it is known that from 16 districts / cities, the most pollutants in air pollution are CO and NO2 and the pollutant with the lowest value is Pb.

LITERATURE REVIEW: KONTAMINASI PESTISIDA DI PERAIRAN INDONESIA

2024-06-07T11:28:35+00:00

Water pollution is a serious problem that affects aquatic ecosystems. Pesticides are used widely in agriculture to control pests and increase crop yields. However, the use of this pesticide causes negative impacts, including water pollution. Pesticides enter the aquatic environment through surface runoff, river flows, and leaching from contaminated soil. Accumulation of ecosystems in aquatic ecosystems can disrupt ecological balance, reduce biodiversity, and potentially poison aquatic organisms. Organophosphates are the most common type of pesticide found in Indonesian waters. Research related to pollution in Indonesian waters amounted to 25 journals with the highest frequency found in 2019. Over the last ten years, research related to pesticide contamination found in waters has been reported by researchers in various regions including West Java, Jakarta, Central Java, East Java , Yogyakarta, Bali, West Sumatra, South Sumatra, North Sumatra, Lampung and Manado.

IDENTIFIKASI BORAKS DAN FORMALIN PADA MIE BASAH DAN BAKSO YANG BEREDAR DI SEKITAR ACEH BESAR DAN BANDA ACEH

Wet noodles and meatballs are popular foods frequently consumed by the community around Aceh Besar and Banda Aceh. However, concerns regarding the use of hazardous substances such as borax and formalin in these food products are a major concern. This study aims to identify the borax and formalin content in wet noodles and meatballs circulating around Aceh Besar and Banda Aceh. The method in this research is a qualitative method using a test kit. The research results showed that the five wet noodle samples and three meatball samples were negative for using borax and formalin.

The scallion (Allium fistulosum L.) is a type of horticultural plant that is in great demand by the people. This study aims to identify the effects the growth of plants a scallion grow regulation (GR) with a combination of coconut water and leri water. The draft in this research is a random group rack consisting of 5 treatment by 5 repetition, the treatment consists of (P0 : control), (P1: 80% coconut water and 20% leri water), (P2 : 60% coconut water and 40% leri water), (P3: 40% coconut water and 60% leri water and (P4 : 20% coconut water and 80% leri water). Parameter observed in this study is leaf length number of leaves and a heavy wetness perpolybag. The result showed that the GR from the combination of coconut water and leri water affected the growth of leaf length, number of leaves and a heavy wetness perpolybag. The best GR combination treatment is the P4 treatment with a concentration of 20% coconut water and 80% rice washing water, namely leaf length (31.28 cm) and wet weight (5.8 g).

PEWARNA ALTERNATIF PREPARAT SEDIAAN APUSAN DARAH TEPI (SADT) DARI EKSTRAK BUNGA KAMBOJA (Plumeria rubra L. cv. Acutifolia.)

Peripheral Blood Smear Preparation (SADT) is a smear preparation made using human blood that is colored for examination in hematology. This examination is done to see and assess peripheral blood cells such as leukocytes, platelets and erythrocytes. Giemsa has a drawback because methylene blue contained in giemsa can be inhaled causing cyanosis. Azur B content can also cause waste because the material contained is not easily decomposed and eosin content can cause allergic reactions.This study aimed to test the water extract of Cambodian flowers (Plumeria rubra L. cv. Acutifolia.) as an alternative dye of peripheral blood smear preparations. This research is in the form of qualitative research with a method of making purple dye for water extraction of frangipani flowers (Plumeria rubra L. cv. Acutifolia.). Microscopic observations of frangipani flower extract (Plumeria rubra L. cv. Acutifolia.) as a preparation of Edge Blood Smear (SADT) can be used as an alternative natural use besides Giemsa staining, because erythrocytes, leokocytes and platelets are able to bind colors well.
