Abstract

Efforts to improve the productivity of a seed source require a deep understanding of reproductive characteristics and environmental factors that affect the seed production. This study aimed to investigate the characteristics of reproduction which include 1) the characteristics of flower morphology and phenology, and 2) the identification of flower visitors of surian. Studies conducted in the smallholder forest in Sumedang, West Java. Surian flowers were compound flower that arranged in panicles shape.When a flower blooms,  petals do not open fully, formed like a tube. Male flowers are smaller than female flowers and never bloom, and the male flowers fall first. Branching patterns of surian flower panicle is thyrses, and flowers bloom not simultaneously. The development of flower from buds to bloom takes approximately 12 days, the flowers bloom 1-3 days, development of fruit until ripe takes 5-5.5 months. It is found 12 species of insects visiting flowers, 11 species are considered very small. Insects those are found in large quantities were Thrips and three species of Nitidulidae.

Abstract

The study was carried out for investigation of the adaptability of white jabon seedlings from 12 populations to drought and water logging stresses in a controlled green house. The results showed that the adaptive responses of white jabon seedling to drought and waterlogging stresses were affected by genotype (population). The drought and waterlogging stresses significantly inhibited plant growth, biomass accumulation and allocation, leaf area, also decreased chlorophyll content, increased carotenoids contents, and accumulated free proline. Relative water content and specific leaf area tended to be higher in waterlogging and declined in drought stresses.  The result clearly indicated that white jabon seedlings were more adaptive to waterlogging than to drought stresses. Moreover, there were different responses to drought and waterlogging stresses between the twelve populations. Kampar, Gowa, Kuala Kencana and OKI populations exhibited higher growth performance and stress tolerance index to be adapted to waterlogging stress, while Gowa, Pomalaa and Kampar populations had relatively better growth performance in the drought stress.

Abstract

Malapari (Pongamia pinnata (L.) Pierre) adalah salah satu bahan baku biodiesel yang paling potensial untuk dikembangkan di Indonesia. Tanaman ini secara alami tersebar mulai dari Sumatera sampai Papua, namun belum diketahui informasi mengenai kandungan minyak dan sifat fisiko-kimia minyak malapari khususnya yang ada di Pulau Jawa. Penelitian ini bertujuan untuk mempelajari komposisi kimia biji malapari, mengidentifikasi komposisi asam lemak dari minyak biji yang dihasilkan dan mengkarakterisasi sifat fisiko-kimia minyaknya. Penentuan komposisi kandungan kimia biji malapari dilakukan dengan analisis proksimat. Analisis sifat fisiko-kimia minyak biji malapari dilakukan dengan metode pengujian ASTM. Hasil penelitian menunjukkan bahwa populasi Batukaras merupakan populasi yang paling baik sebagai sumber bahan baku biodiesel karena mempunyai nilai kadar minyak tertinggi. Keunggulan lain dari populasi Batukaras memiliki nilai berat jenis, viskositas, dan bilangan asam yang terendah. Minyak malapari didominasi oleh asam lemak oleat dan linoleat yang merupakan asam lemak tidak jenuh yang berpotensi untuk biodiesel. Berdasarkan nilai asam lemak (oleat dan linoleat) dan sifat fisiko kimia (berat jenis dan nilai kalor) minyak mentah malapari dari kelima populasi telah memenuhi syarat untuk dijadikan bahan baku biodiesel.

Abstract

Ebony (Diospyros celebica Bakh) is an endemic forest tree species found in Sulawesi whose basic information on its metabolite profile is still lacking. The objective of this research was to separate and identify putatively metabolite present in the leaves and wood of ebony across Sulawesi. Separation and identification of ebony metabolites were carried out using UHPLC-Q-Orbitrap HRMS analysis. Using ultrasonication with ethanol as the extracting solvent, we used powdered ebony leaves and wood. The results showed that the metabolites contained in the leaves and wood of ebony were 59 metabolites. About 14 compounds were found in the leaves and wood, 21 compounds in the wood, and 24 compounds in the leaves. The identified metabolites are flavonoids, terpenoids, amino aldehydes, alkaloids, quinones, steroids, amino acids, fatty acids, and saccharides. Clustering of ebony using principal component analysis obtained leaves and wood groups using peak area of known compounds as the variable.

Abstract

Mindi (Melia azedarach L.) is mostly found in community forests of West Java. One of the important factors affecting productivity of community forests is the use of quality seed. Due to scarcity of seed sources, however, seed quality is not easily available. Currently, community forests serve also as ad hoc seed sources that are usually without appropriate quality assessment. This research was aimed to determine baseline information on spatial variability of mindi fruits collected from five seed sources, and seedling growths treated in seven different growing media consisting mixtures of soil, rice husk, sand and cattle manure. Five mindi populations were selected in the following villages: Nagrak (Bogor), Babakan Rema (Kuningan), Padasari (Sumedang), Sukakarya (Bogor) and Gambung (Bandung). The results showed that variability of seed dimension (CV=4.82-14.37%) and seedling growth (11.79-21.77%) were moderate. The mindi fruits from Nagrak were found to be the biggest in terms of size (1.22 ± 0.17 cm), weight (0.40 ± 0.04 g), and seed set (85.47 ± 15.09%). In addition, the seedling growth from Nagrak was also better than those of other villages showing its potential for future seed sources. Growing media containing cattle manure were observed consistently to be the best for seedling growth. The findings are useful in supporting scientifically the selection of seed sources from community forests.

Abstract

The amount of data in this world is getting higher, and overwriting technology also has severe challenges. Data growth is expected to grow to 175 ZB by 2025. Data storage technology in DNA is an alternative technology with potential in information storage, mainly digital data. One of the stages of storing information on DNA is synthesis. This synthesis process costs very high, so it is necessary to integrate compression techniques for digital data to minimize the costs incurred. One of the models used in compression techniques is the generative model. This paper aims to see if compression using this generative model allows it to be integrated into data storage methods on DNA. To this end, we have conducted a Systematic Literature Review using the PRISMA method in selecting papers. We took the source of the papers from four leading databases and other additional databases. Out of 2440 papers, we finally decided on 34 primary papers for detailed analysis. This systematic literature review (SLR) presents and categorizes based on research questions, namely discussing machine learning methods applied in DNA storage, identifying compression techniques for DNA storage, knowing the role of deep learning in the compression process for DNA storage, knowing how generative models are associated with deep learning, knowing how generative models are applied in the compression process, and knowing latent space can be formed. The study highlights open problems that need to be solved and provides an identified research direction.
