Abstract

Infeksi jamur di daerah tropis termasuk Indonesia relatif tinggi. Salah satu jamur yang dapat menginfeksi yaitu Trichophyton mentagrophytes yang dapat menyebabkan penyakit kulit seperti tinea pedis, tinea kruris dan lainnya. Sebagai alternatif pengobatan digunakan ekstrak biji mimba. Salah satu manfaatnya sebagai antijamur. Tujuan penelitian untuk mengetahui kemampuan ekstrak biji mimba dalam menghambat pertumbuhan Trichophyton mentagrophytes dan mengetahui perbandingan efektivitas masing-masing ekstrak biji mimba terhadap Trichophyton mentagrophytes. Metode ekstraksi yang digunakan yaitu maserasi bertingkat dengan menggunakan pelarut n-heksan, diklorometan dan metanol. Uji aktivitas antijamur menggunakan metode sumuran. Data yang dihasilkan di analisis menggunakan Post-Hoc Least Significant Difference (LSD ) dan kandungan senyawa pada masing-masing ekstrak di analisis menggunakan instrument GC-MS. Hasil penelitian menunjukkan bahwa ekstrak n-heksan memiliki daya hambat yang paling tinggi dibandingkan dengan ekstrak diklorometan dan metanol. Rata-rata diameter zona hambat ekstrak n-heksan yaitu 11,12 mm, ekstrak diklorometan 10,37 mm dan ekstrak metanol 9,75 mm. Hasil analisis senyawa menggunakan GCMS ekstrak biji mimba mengandung asam palmitat, asam stearat dan heptadecene-8-carbonic acid yang diduga memiliki sifat sebagai antijamur. Hasil analisis One Way Anova yang dilanjutkan dengan uji Post Hoc Least Significant Difference (LSD) menunjukkan ekstrak n-heksan, diklorometan dan metanol memiliki aktivitas yang sama dalam menghambat pertumbuhan jamur Trichophyton mentagrophytes (p>0,05).

Abstract

Development progress that occurred in the city of Semarang has an impact on increasing community economic activity. This increasing carbon emissions in the air occured due to the use of fossil fuels. One of the efforts to reduce carbon emissions is by reforestation. The city of Semarang has 19.541 hectares (52.31%) of green open space out of 37.303,9 hectares of the total area of the city. However, the area of the mangrove ecosystem in Semarang City was only 68,13 Ha. Even though mangrove ecosystems have a higher ability to absorb carbon than other ecosystems. Based on these conditions, it was necessary to estimate mangrove carbon stocks as an effort to determine the potential of mangrove tree strata to absorb carbon. From the results, the value of mangrove carbon stocks in the Trimulyo mangrove ecosystem of 36,00 tons/ha had the potential to act as a carbon sink.

Abstract

Tunda Island is one of the leading marine destinations in Banten Province which has high potential biodiversity. This study aimed to determine the health condition of the Tunda Island coral reef ecosystem. The method used in this study was Line Intercept Transect (LIT) method for coral reef and Belt Transect method for reef fish. Based on coral reef survey, the percentage of coral coverage on Tunda Island was 34.7%. From this value the coral reefs of Tunda Island were included in the sufficient category. The results of a survey of fish showed that there were 57 species from 17 families, which is dominated from Pomacentridae. The diversity index value (H ') of reef fish was 3.143, which showed that the diversity of reef fish around Tunda Island was high, and the uniformity index value (e) was 0.777, which showed that in Tunda Island waters the spread of fish species was stable.

Abstract

Jumiang Beach is one of the beaches on the southern coast of Pamekasan Regency, Madura. Jumiang Beach is one of the tourist destinations in the Pamekasan area with varying levels of diversity of aquatic living things. Through this ecological research, we present the pattern of population distribution in the current Jumiang Coast region with the aim of providing information related to the diversity of living things that exist in the region. The pattern of distribution is described as the condition/condition of living creatures in the region whether or not good enough in its development or that causes the level of diversity has decreased. The method used in the form of descriptive and quadrant methods by applying misneting techniques in the form of exploratory which produces data patterns of population distribution in the form of index morisita. The results of the study stated that the pattern of population distribution in the Jumiang Coast region was classified as a group with a morisita index value of more than one.

Abstract

Urban parks in South Jakarta are the main component of green open spaces which act as habitat for birds in the cities. Aim of this study was to determine the diversity of bird species around the South Jakarta City Park. The research was conducted in October-November 2021 in the city parks of Spatodea and Tabebuya, South Jakarta. Bird data collection used the point count method, while plant data collection used an inventory system. Results showed that the Tabebuya Park location had 9 species of birds from 8 different families, while in Spatodea Park there were 8 bird species found. The Tabebuya City Park was found to have medium species diversity index value, medium evenness index value and low dominance value index. Spatodea city park had a low value index of species diversity, low evenness value index, and low dominance value index. The highest number of bird species obtained was 7 species in total. The results showed that the urban park area in South Jakarta had low to moderate range of bird species diversity. This could happen because birds in urban landscapes tended to be more sensitive to the presence of certain stratification of vegetation, especially tree stratification.
