Climate change increases the concentration of the greenhouse effect, this was caused by the lack of trees as a function of carbon sequestration. Therefore, this study aims to map the vegetation distribution in the streets of the city of Malang and to measure its carbon stocks. The used method was vegetation analysis, to calculate the estimation of biomass, carbon storage and CO2 absorption using the allometric equation Brown; Brown and Lugo; and Morikawa. The study was conducted at the street lots of traffic activity, there are six stations representing the city of Malang, those are Tlogomas Street, North of Ahmad Yani Street, Letjend Sutoyo Street, Panglima Sudirman Street, Sudanco Supriadi Street and Kolonel Sugiono Street. The results of this study are that the most carbon-absorbing tree is Albizia saman with a value of 287,656 kg and the region that absorbs the most carbon is Panglima Sudirman Street, that located in the middle of the city.
This research abjective is to analyze the difference of abundance, diversity and composition of canopy insect in Poncokusumo and Bumiaji on blossoming and fruiting seasons. Insect compostions were observed by regular sampling using blue and yellow water pan trap. Water pan traps were suspended on apple stands at 2m height. Sampling efforts was done by block system on 5 trees with 4 times collection, resulting 20 replications. Difference of mean was tested using general linear model analysis of variance. The canopy insect compositions between location were compared using Bray-Curtis similarity index. Overall, canopy insect diversity in twostudy sites was low. The abundance and diversity of canopy insect in Poncokusumo was higher than that in Bumiaji. The abundance and diversity of canopy insect in yellow traps was higher than that in blue traps. The effect of flowering phenology was significant on the overall abundance but not for the diversity. The effect of study locations on the abundance interacted with season. This meant there was a seasonal variation afecting location.
One of the biggest threats from human activities to rivers is the increasing number of residential areas around or even just above the river flow. This condition is certainly very threatening the sustainability of rivers in the region. One of the biggest threats is that the garbage produced by the community will be directly disposed of in the river flow. One way that can be done to reduce waste disposal in the river is by utilizing river flow, so that many rivers are now increasingly being developed as a vehicle for habitat conservation, because the river is considered important for various aquatic plants, migratory and sedentary fishes, and aquaculture ponds, birds and several types of mammals. In this case, the concept of river management must be based on environmental, ecological, economic and social aspects according to the characteristics of the surrounding community. The purpose of this community service is to utilize river flow for tilapia fish farming. The method used in the service is the PAR by way of lectures and direct practice in aquaculture with karamba by utilizing river flow. From the results of community service including partners showed that some respondents know how to fish with karamba, but do not know that river flow can also be used for fish farming with the karamba system. As well as the results of fish farming practices with the karamba system most of the respondents agreed agree (73%) if the fish culture using the karamba system is used as an alternative business idea related to river flow utilization and 60% of respondents agree the use of river flow for fish cultivation can reduce waste disposal in the river.
The purpose of this study was to determine the structure and condition of seagrass communities in the waters of hadirin Beach and Batu lawang karimunjawa. national park. This exploratory research used descriptive qualitative methods, each study location is divided into two transects. Data identified at SPTN Office 1 Kemujan Karimunjawa National Park. The results of the study were six species of seagrass, namely: Holodule uninervise, Thalassodendron ciliatum, Halophila minor, Syringodium isoetifolium, Thalassia hemprichii and Cymodocea serrulata. The percentage of seagrass cover namely Holodule uninervise is 38.04 %. Thalassodendron ciliatum of 6.25%, Halophila minor of 29.56%, Syringodium isoetifolium of 31.25%, Thalassia hemprichii at 14.21% and Cymodocea serrulata to 16.9%. The highest density of seagrass species in Hadirin Beach is from the Uninervise holodule species 72.30%, with 858 stands on the first transect and 54.66% on the second transect with 253 stands. Whereas for the highest Batu Lawang Beach is the species of Thalassia hemprichii 51.1% with 162 stands, on the first transect and 44.9% with 114 stands. The substrate has the type of sandy clay and coral fragments. Holodule uninervise is the most dominant species found on the beach of Hadirin meanwhile Thalassia hemprichi is the most dominant species in Batu Lawang.
Avifauna merupakan kelompok hewan yang mempunyai posisi penting sebagai salah satu kekayaan satwa di Indonesia. Avifauna berperan besar dalam penyebaran benih dan sebagai salah satu bioindikator lingkungan. Penelitian tentang inventarisasi dan distribusi spasial avifauna diurnal di Coban Kodok Desa Sukomulyo Kecamatan Pujon Kabupaten Malang dilakukan pada tanggal 19-20 April 2020 pukul 06.00-08.00 dan 15.00-17.00 WIB. Penelitian ini bertujuan untuk mengetahui jenis dan distribusi spasial avifauna di Coban Kodok. Penelitian ini menggunakan metode IPA (Indices Ponctuel d'Abondance) di dalam zona pengamatan. Analisis data melalui deskriptif eksploratif dan metode statistik multivariabel yang didasarkan pada Analisis Korelasi (Correspondence Analysis, CA) untuk mengetahui jenis populasi dan distribusi spatial avifauna di Coban Kodok. Hasil penelitian menunjukan bahwa pada zona 1 (agriladang barat) ditemukan Todiramphus chloris sebanyak dua individu, Apus nipalensis sebanyak dua individu, Pycnonotus aurigaster sebanyak tiga individu dan Spilopelia chinensis sebanyak dua individu, sedangkan pada zona 2 (agriladang timur) ditemukan Todiramphus chloris sebanyak empat individu, Apus nipalensis sebanyak empat individu, dan Lonchura maja sebanyak empat individu
Seagrass is a flowering plant that lives in coastal areas In Indonesia there are 12 species, where seagrasses are able to live at a depth of 1-90 meters, seagrass growth is influenced by several factors including the intensity of sunlight. The purpose of this study was to observe the cover, distribution, Importance Value Index (IVI) and correlation of abiotic factors with seagrass in Jhembangan Beach and White Sand on Bawean Island, East Java. The quadratic transect with 50 m length was used. Each station equipped with 3 transects with a distance of 25 m. The data collected includes the parameter of type, stand, and water quality. The data analyze use Past Program 3.15 systems. Three species of seagrass plant were collected. The total seagrass cover value was 32.6 percent at Jhembangan Beach, and 38 percent at Pasir Putih Beach. Clumped and uniform types were included in the distribution of seagrass at Jhembangan and Pasir Putih beach. The highest of important value index In Jhembangan and Pasir Putih was Thallasia hemprichii, while the association to abiotic factor such temperature, pH, salinity and DO variables are included in the good or perfect correlation with values range from 0.7 to 0.9.
Indonesia is a country that has a very large tropical rain forest. The forest is a unified biological system as part of the earth there is an ordinary organic wealth covered with trees which in cooperation in their nature and current state cannot be separated. Groundcover is a basic vegetation component under forest stands other than tree rejuvenation, which consists of grasses, herbs and shrubs. Bromo Tengger Semeru National Park (TNBTS) is a conservation area with abundant biodiversity, both in terms of flora and fauna. The purpose of this study was to determine the genus of the undergrowth and dominancefound in the Ireng-Ireng Block Utilization Zone, Bromo Tengger Semeru National Park. The research method uses line and transect plots with 4 transects 20 m long, each with 5 plots measuring 1 x 1 m with a distance between plots of 3 m. Result research Found 13 genera as follows Davallia, Strychnos, Homalomena, Nheprolepis, Pheghopteris, Pteris, Ageratina, Sceleria, Molineria, Didymochlaena, Adiantum, Begonia, and Ruellia. The understorey plants that had the highest cover were from the Strychnos genus group with an important value index of 26.87 . Keywords: structure, komposition, Groundcover, ireng ireng block utilization zone Bromo Tengger Semeru National Park.
