Abstract

Nepenthes spp. is a typical plant of Southeast Asia especially Indonesia which has a special leaf modification called a pitcher. The largest number of Nepenthes spp. species in Indonesia is on the island of Sumatra. The purpose of this reseach was to identify and analyze cluster Nepenthes spp. from South Sumatra based on morphological characteristics. The specimens were collected from the forest of Tekorejo Village, Air Itam Village and cultivation location in Palembang city of South Sumatra. Identification of morphological characters performed on the characteristics of root, stem, leaves, and pitcher. The morphological data is used for cluster analysis using NTSYS software version 2.02. The identification results showed 9 variants of Nepenthes spp. which belong to the species N. mirabilis, N. gracilis, and N. sumatrana. Dendogram analysis results form two main clusters with a similarity value of 22%. The first cluster consists of N. mirabilis and N. sumatrana. The second cluster consists of N. gracilis. Based on the results of this study can be concluded that the species Nepenthes spp. South Sumatra is N. mirabilis, N. gracilis, and N. sumatrana. The results of this study will be dedicated to updating information about the existence of Nepenthes spp. from South Sumatra and his cluster.

Abstract

Gas buang yang dihasilkan oleh kendaraan bermotor pengguna bahan bakar bensin bertimbal mengemisikan Pb ke dalam lingkungan dan berpotensi terserap ke dalam jaringan daun tanaman peneduh jalan. Penelitian bertujuan untuk menguji kandungan timbal (Pb) dalam daun tanaman peneduh di jalan protokol Kota Semarang. Sampel penelitian adalah daun angsana (Pterocarpus indicus Willd), glodokan (Polyalthia longifolia Bent & Hook. F) dan mahoni (Swietenia mahagoni (L.) Jacq.) yang dominan digunakan sebagai peneduh di lima jalan protokol Kota Semarang yaitu Jl. Kalibanteng, Jl. Pemuda, Jl. Brigjen Katamso, Jl. Kaligawe dan Jl. Setyabudi. Kandungan Pb dalam daun tanaman angsana, glodokan dan mahoni diuji menggunakan metode AAS (Atomic Absorption Spectrophotometery) di Laboratorium Balai Besar Teknologi Pencegahan Pencemaran Industri (BBTPPI) Semarang. Hasil penelitian ditemukan kandungan Pb dalam daun tanaman peneduh di jalan protokol Kota Semarang. Kandungan Pb dalam daun tertinggi 0,05 ppm/g daun basah terdapat pada tanaman angsana dan terendah sebesar 0,01 ppm/g terdapat pada tanaman glodokan dan mahoni. Dari hasil penelitian disimpulkan bahwa kandungan Pb dalam daun tanaman peneduh di jalan protokol Kota Semarang berkisar 0,01-0,05 ppm/g daun basah dan tergolong rendah dibawah kadar normal Pb dalam tanaman yaitu 0,5-3,0 ppm.Exhaust gases produced by motor vehicle users leaded gasoline emits Pb into the environment and potentially absorbed into the leaf tissue of plants along the roadside. The study aimed to examine the content of lead (Pb) in the shade plant leaves in the Semarang City road protocol. Samples were angsana leaves (Pterocarpus indicus Willd), glodokan (Polyalthia longifolia Bent & Hook. F) and mahogany (Swietenia mahagoni (L.) Jacq.). They were predominantly used as a shade in five main streets of Semarang is Kalibanteng St, Youth St, Brig Katamso St, Kaligawe St and Setyabudi St. The content of Pb in the Angsana, glodokan and mahogany leaves were tested using AAS (Atomic Absorption Spectrophotometery) method in Great Hall of The Pollution Prevention Technology Laboratory Semarang. The results showed that the content of Pb was found in the shade plant leaves in the Semarang road protocol. The highest Pb content in leaves was 0.05 ppm/g wet leaves at Angsana plants and the lowest was 0.01 ppm/g contained in mahogany and glodokan plants. Based on the results of this study, it concluded that the content of Pb in the shade plant leaves in the Semarang protocol ranged from 0.01 to 0.05 ppm/g wet leaves and relatively low under normal levels of Pb in plants is 0.5 to 3.0 ppm.

Abstract

Stem cell technology has great potential in the effort to cure degenerative diseases. This study was done to determine optimum dose of flamboyant (Delonix regia) flower extract to induce proliferation and differentiation of mice (Mus musculus) bone marrow mesenchymal-like stem cell. Bone marrow cells were collected from mice by aspiration. Cells suspension (1 x 106) were poured into petri dishes containing 2 ml of modified Dulbeccos Modified Eagles Media (mDMEM) and incubated overnight at 37 °C in a 5% CO2 incubator and microscopically observed. In quadriplicate, MSC were cultured in mDMEM containing D. regia flower extract of 0.0 (control), 0.4, 0.6, 0.8, and 1.0 mg/ml and incubated at 37 °C for 9 days. Population doubling time (PDT) and differentiated cell type were microscopically observed using HE staining on day 1 and 10. Data obtained were analyzed by ANOVA and Tukey test. The results showed that the addition of D regia flowers extracts 0.8 and 1.0 mg/ml significantly reduced PDT compared to that of 0.4, 0.6 and control. The extract, at 0.4 and 0.6 mg/ml, were able to induce MSC differentiation into fibroblast-like and nerve-like cells. In conclusion, D. regia flower extracts of 0.6, 0.8 and 1.0 mg/ml were able to stimulate MSC proliferation, but optimum dose for neurogenic differentiation was 0.6 mg/ml. This is the first to show potential of D. regia flower extract as neurogenic differentiatian inducer on mice MSC. These findings can be used as preliminary information for using the extract as cellular differentian inducer in basic and applicative reseach using stem cells.

Abstract

AbstrakTujuan penelitian ini adalah untuk mengembangkan bahan edible coating (EC) alami dari ekstrak daun randu; serta mengetahui pengaruhnya terhadap mutu dan umur simpan mentimun. Rancangan penelitian menggunakan RAL dua faktor yaitu konsentrasi EC, (0%, 50%, 100%), dan suhu penyimpanan (suhu ruang dan suhu rendah). Parameter yang diukur adalah perubahan berat, total padatan terlarut (TPT), pH, warna, kekerasan dan kebusukan mentimun. Hasil penelitian menunjukkan bahwa penurunan berat mentimun yang disimpan pada suhu ruang paling rendah terjadi pada perlakuan kontrol (tanpa EC), sedangkan penurunan berat paling rendah pada penyimpanan suhu rendah adalah perlakuan EC konsentrasi 100%. Perlakuan terbaik untuk mempertahankan mutu (pH, TPT, warna, kekerasan dan kebusukan) terdapat pada kombinasi perlakuan EC ekstrak daun randu konsentrasi 100% dalam penyimpanan suhu rendah. Kombinasi perlakuan tersebut menghasilkan umur simpan mentimun yang paling lama sampai 9 hari.AbstractThe purpose of this study was (1) to develop edible coating material (EC) is a natural, easy to make and widely available, the ceiba pentandra leaf extract, and (2) to determine the effect of the EC material on the quality and shelf life of cucumber.

Abstract

In freshwater ecosystems, water temperature plays as an environmental factor that regulates its structure and function. A research on the impacts of changes in temperature to the dynamics of the Phytoplankton community structure has been done. Data from nineteen-year period (1995 to 2013) were collected from Cirata Reservoir as an example of artificial tropical lake in Indonesia. The research aimed to determine the changes of water temperature as the impact of climate warming on the dynamics of phytoplankton community structure. Different measures such as species richness, diversity index, and abundance were measured in order to understand the changes of phytoplankton community structure. Trend analysis, linear regression, and correlation were applied to achieve our objective. The study revealed that changes in water temperature have affected the species richness, but not the diversity index and abundance of the phytoplankton. Bacilariophyceae and Cyanophyceae were found as two predominant phytoplankton classes in the lake with percentage of 48,45 and 41,43 respectively, assuming their capacity to adapt the new environment. This study suggests that climate warming implies changes of the freshwater ecosystems.

Abstract

Termites cause a lot of damage and big losses for building components, especially those made of wood. High population growth and rapid infrastructure development in Semarang city affect the natural habitats of termites. This phenomenon changes the termites behavior of foraging in buildings. Semarang city has humidity, temperature, and altitude that allows termites to live and breed well. The purpose of this study was to determine the types of termites living in housing in Semarang city as well as the level of attacks on housing. This research was conducted in nine housing in Semarang City. The research was carried out with two methods: building inspection and wood-feeding method by using Pinus mercusii wood measures 2 cm x 2 cm x 46 cm. The results found four types of termites that attack wood feeds namely Macrotermes gilvus, Microtermes inspiratus, Odontotermes javanicus, Coptotermes curvignathus and Cryptotermes sp.. Based on interviews and building inspection, it was known that the condition of the building in the category of "moderate" was occupying the most position (74.44%), good (17.78%) and lightly damaged (7.78%). From the causes of damage to building components, it can be concluded that the level of termite attack against damage to recidential buildings in Semarang city 44.58%. Cross-tabulation analysis of Chi-Square shows that there is a correlation between age and treatment with damage to the building. Futher, the finding can be used as baseline information for further scientific investigation for effective termites control on residential building components.
