L-Erythrulose-1-C14 and -4-C14 were used as precursors in the biosynthesis of 4-O-β-D-mannopyranosyl-D-erythritol. The ketose was utilized efficiently and the C14 distribution pattern in the product indicated that the 4-carbon fragment was transferred intact to C-3, C-4, C-5, and C-6 of the mannose moiety and was also reduced intact to the erythritol portion.A method for the degradation of D-mannose for determination of the C14 distribution in the molecule is described.

This study aims to analyze the distribution pattern of aboveground biomass (AGB) in the mangrove ecosystem of West Kalimantan Safety. In addition, it also analyzes the differences in biomass and carbon stocks in the condition of mangrove forests. The study of the distribution pattern of AGB of mangrove forests was carried out between August and September 2018. Determination of the location of the study was based on a conceptual approach in the dimensions of spatial temporal that is using the Porposive Random Sampling method. Vegetation analysis was carried out by a single plot measuring 50 m x 50 m at each selected location. Based on vegetation analysis data it was found that the density of mangrove stands on the Peniti coast ranged from 38 to 185 ind /ha, with an average of 88.25 ± 66.15 ind./ Ha. The AGB of pinch mangrove forests ranged from 8.85 to 84.82 Mg / ha with the largest total AGB distributed in the stand diameter class of more than 80 cm.   Penelitian ini bertujuan untuk menganalisis pola distribusi aboveground biomass (AGB) pada ekosistem mangrove Peniti Kalimantan Barat. Selain itu juga untuk menganalisis perbedaan biomassa, dan cadangan karbon pada kondisi hutan mangrove. Kajian pola distribusi AGB hutan mangrove Peniti dilakukan antara bulan Agustus dan September 2018. Penentuan lokasi penelitian didasarkan pada pendekatan konseptual dalam dimensi spasio temporal yaitu menggunakan metode Porposive Random Sampling. Analisis vegetasi dilakukan dengan metode petak tunggal berukuran 50 m x 50 m pada setiap lokasi terpilih. Berdasarkan data analisis vegetasi didapatkan bahwa kerapatan tegakan mangrove di pesisir Peniti berkisar antara 38 sampai 185 ind/ha, dengan rata-rata 88,25±66,15 ind./ha. AGB tegakan hutan mangrove Peniti berkisar antara 8,85 sampai 84,82 Mg/ha dengan total AGB terbesar terdistribusi pada kelas diameter tegakan lebih dari 80 cm.

<p class="JGI-AbstractIsi">This study provides an overview of signal distribution pattern using Cost-231 Multi-Wall (MWM) propagation model. The signal distribution pattern is used as a reference in projecting indoor Access Points (AP) placement in Malang Institute of Asia. The MWM approach estimates the actual radio wave propagation value for measurements are made by considering obstacles between APs and user devices. The study recommends 10 optimal points of AP placement for the 1st, 3rd and 4th-floors, and 7 optimal points for the 2nd-floor. Determination of these placement points was based on the estimated signal strength obtained by users, at -50dBM up to - 10dBm, which is the range for good and excellent signal category.</p>

Abstract This study aims to determine the distribution pattern, morphological and agroecological characteristics of Purwoceng Gunung. The research location on the slopes of Mount Lawu, around the Grojogan Sewu, Tawangmangu sub-district. The sampling point was determined based on purposive random sampling through a pre-survey. Determination of sample plots and analysis of vegetation using the transect (line) method. The results showed that the stem shape was round and segmented, smooth surface and green, oval leaf shape with serrated edges, compound leaves, pointed leaf tip, blunt leaf base, green leaf color with a length of 4 cm and a width of ± 2 cm. The location of the flowers at the end of the stem and classified as compound interest, fibrous roots with yellowish white color. The distribution pattern of Purwoceng Gunung was uniform with low population density of 6 individuals per plot and an INP of 4.4. Habitat agroecological conditions with climate type C with the following soil chemistry: C organic 5.8%, organic matter 9.9%, N 0.27 %, P 16.04 %, K 0.27 %, pH NaF 9.02, pH H2O 6.1, CEC 26, 9 me 100 g-1, field capacity 43.9. The proportions of dust, clay and sand were 27.4%, 9.4% and 63.2% respectively.
