Abstract Sago palm (Metroxylon sagu Rottb.) is one of the most potential starch-producing crops, however its utilization has not yet optimal, only around 10%, and mostly from sago trees grown near the villages. The objective of this research was to collect data of the potentially productive trees which are Mid Trunk (MT) and Mature Palm (MP) at sago forest of Sentani, Papua province. Survey method was used for this research by making inventory tracks into three plots as subpopulation and three inventory tracks in every plot with 100 m length and 50 m width, and the distance between tracks was 150 m to find out the spreading and approximation of potential trees through multistage analysis. The observed parameters were number of cluster, number of MT and MP for every types of sago palm. The results show that there were three intra-species of spiny sago palms called Yakari, Bata, and Dondo, and two intra-species of unspiny sago palms called Yebha and Ojokuru. The dominant sago type was Yebha. The cluster was spreading sporadically with coefficient of variance (CV) at 24.3, The predicted number of MT was higher than MP. Numbers of MT and MP for every hectare of sago forest were very low, 1.3 MT/ha and 0.3 MP/haAbstrak Tanaman sagu (Metroxylon sagu Rottb.) merupakan tanaman penghasil karbohidrat yang sangat potensial, namun pemanfaataannya masih belum optimal, yaitu hanya sekitar 10%, dan sebagian besar merupakan tanaman sagu yang tumbuh di sekitar perkampungan. Tujuan dari peneli-tian ini adalah mendapatkan data pohon yang berpotensi produktif yaitu pohon Belum Masak Tebang (BMT) dan  pohon Masak Tebang (MT) di kawasan hutan sagu Sentani, provinsi Papua.  Metode survai digunakan pada penelitian ini dengan membuat jalur-jalur inventarisasi dalam  tiga plot sebagai sub-populasi dan  tiga jalur inventarisasi di setiap plot dengan panjang jalur 100 m, lebar jalur 50 m dan jarak antar jalur 150 m untuk mengetahui tebaran dan penaksiran potensi pohon melalui  analisis multi tahap.

This study aims to map the condition of land where sago plant grows, to determine the suitability level of sago plant land and to describe the potential of sago and sago consumption patterns by the community. The method used in this research is survey method with distance observation free survey and pit profile observation type. The condition of the land where sago plants grow is quite good.

The size of sago palm in Rumahkay Village is 55.5 Ha, the average number of cutting trees (MT) 24 trees / Ha / yr with average production of wet starch per tree sebesr 700 kg. Total dry starch production at the study site was 449.55 tons. The pattern of community consumption of sago 10 percent, the combination of sago, tuber and banana by 20 percent, the combination of sago, tubers, bananas and rice by 55 percent and rice 10 percent.

Metabolite Markers

Background: Sago palm is an important agricultural starch-producing crop in Malaysia. The trunk of sago palm is responsible for the production of the starch reaching maturity for harvesting after ten years. However, there are sago palms that failed to develop its trunk after 17 years being planted. This is known as a stressed “non-trunking” sago palm, which eliminates the economic value of the palms. Objective: The study was initiated to compare the differences in metabolite expression between trunking and non-trunking sago palm and secondly to determine the potential metabolite-makers that are related to differential phenotypes of sago palms. Method: Metabolites were extracted using various solvents and analysed using NMR spectroscopy and GC-MS spectrometry. Data obtained were subjected to principal component analysis. Results: The study determined that differential metabolites expression were detected in the leaf extracts of normal trunking sago palm compared to the non-trunking palms. Metabolite groups which are differently expressed between trunking and non-trunking sago palm are oils and waxes, haloalkanes, sulfite esters, phosphonates, phosphoric acid, thiophene ester, terpenes and tocopherols. GC-MS analysis of Jones & Kinghorn extraction method determined two sets of metabolite markers which explains the differences in metabolites expression of trunking and non-trunking sago palm in ethyl acetate and methanol extract of 89.55% comprising sulfurous ester compounds and 87.04% comprising sulfurous ester, sulfurous acid and cyclohexylmethyl hexyl ester respectively. Conclusion: Two sets of metabolite markers were expressed in the trunking and non-trunking sago palm. These metabolites can potentially be used as markers for identifying normal and stressed plants.

Mangrove Forest has a role for the life of fauna as a source of feed and shelter for honeybees. Honeybees need feed to maintain their survival in nature, so that the availability of the feed generated by flowers in the form of nectar and pollen gives the ability of bees to breed with maximum. This research aims to obtain the type of mangrove plants and pollen, and its potential in Surya Perdana Mandiri Mangrove Forest area. The research method used is a survey method with the example tile determination Purposive Sampling. There are 10 sample compartments of 20 x 20 meters in 2 research lines. Based on the results of the research is known that there are 22 types of mangrove plants, based on observations, 13 of which are the source of honey bee feed, and based on the study of literatures there are 18 The potential feed bees at the highest tree level on the Api-api putih (Avicemia Marina) with an INP value of 82.17% and the smallest value Ceriop decandra 17.50% while at the highest INP stake level of Rhizopora stylosa 76.08% with flowering 83.44% while the smallest INP Ceriop decandra 22.63% with flowering 36.36%.
