Abstract

Damar (Agathis labillardieri) is endemic species to New Guinea, occurring naturally in Papua and West Papua Province, Indonesia. The species is economically valuable due to its resin and wood. This research aimed to study the cones and seeds characteristics of A. labillardieri collected from Sorong Nature Park at Klasaman, Sorong, Papua Barat. The characteristics observed included cone size and weight, number of scales, empty and filled seed, and seed moisture content. The germination test was also performed. Although the stands could produce cones, not all scales contained seeds, and not all seeds were filled seeds. On average, 53 filled seeds per cone or only 50.3 ± 5.7% of the total seeds found as filled seeds. The seed was characterized as a recalcitrant seed with high moisture content and rapid germination. On average, the seed moisture content was 38.9%, with an average germination time of four days. The combined factors that may contribute to the low natural regeneration of A. labillardieri are low filled seeds, seed sensitivity to desiccation, and high mortality in newly emerging seedlings during recruitment. Therefore, facilitating the forest floor for immediate germination of recalcitrant seeds as in A. labillardieri is suggested. Keywords: Agathis labillardieri, filled seed, germination, natural regeneration, recalcitrant seed

Abstract

This current study of Freycinetia was carried out in Timika, West Papua. Results indicate that species vary in both morphological characters and habitat preferences. Timika is unique as only in this area species with highest number of segments in a berry and of stigmatic remains are found. Exceptional characters regarding to auricles, areolas, and stigmatic remains are observed in many species in this area. The result of this current study suggests that the ability of species to adapt to the widespread forest disturbances in Timika leads to their differences in morphological features compare to other Papuan species. Subsequently, seven new species are described here.

SINAGA, N. I., MEGIA, R., HARTANA, A., KEIM, A. P. Ecology and distribution of Freycinetia Gaud. (Pandanaceae; Freycinetoidea) in Indonesian New Guinea. Reinwardtia 13(2): 189-197. - The study mainly concerns with the species of Freycinetia that occurs in the Indonesian New Guinea, including the provinces of Papua and Papua Barat. The study indicates that almost all species of Freycinetia in the Indonesian New Guinea prefer high humidity and abundantly occur along rivers, except for the members of the group of species with imbricate leaves, which inhabit also secondary forests. Futhermore, the members of this group have never been found within the range of 1700 to 3000 m altitudes. This highest range of altitudes is specifically occupied by the members of the groups of species with semi imbricate and grass-like leaves. The costal forests are inhabited by the groups of species with semi and non imbricate leaves. Indonesian New Guinea shares many species with Papua New Guinea, except for the members of the group of species with semi imbricate leaves, which are more common in Indonesian New Guinea than in Papua New Guinea. On the contrary, the members of the group of species with grass-like leaves are more common in Papua New Guinea and becoming rare toward the Indonesian site and becoming absent in the Vogelklop (Bird's head), except for F. polyclada which is commonly found in Sorong. Indonesian New Guinea possesses 34 species exclusively distributed in the area, while Papua New Guinea has 72 species. The two areas share 52 species. Only five species have extra New Guinean distributions, i.e. F. excelsa, F. funicularis, F. marginata, F. percostata, and F. scandens.

Abstract

ABSTRACT : The Pandan tikar (Pandanus tectorius Park.) was found in many coastal areas, has the potential to be processed into various food products. This study aims to study the diversity of 6 Pandan tikar fruits originating from several locations of Papua and West Papua province based on their physical characteristics and nutritional content. The method used in this study is an exploration method with observations. The origins of the six Pandan tikar fruits were Mansinam (P1), Mansinam (P2), Pasir Putih (P3), Arboretum Fahutan (P4), Hamadi (P5), and Kampung Wardo (P6). The results of this study indicate that the 6 fruits of Pandan tikar observed have a varied shape, namely ovoid (P1 and P2), ellipsoidal (P3), sub-globose (P4 and P6), and globose (P5); with variations in the colour of the fruit flesh, namely yellow (P1, P2, P3, P4), orange (P5), and red (P6). Fruit size dimensions varied; with whole fruit weight 1.8-6.0 kg, length 19.0-23.3 and width 15.0-25.3 cm, fruit circumference of 56-80.5 cm. The total weight of phalange was 1.6-5.75 kg/fruit with a total of 45-152 phalange/fruit, the width and weight of phalange were 3.2-4.5 cm and 24.8-53.8 g/fruit, respectively; while the weight of edible part was 6-21 g/phalange, and the percentage of edible part was 28.0-39.4%/fruit. Total soluble solids (TSS) 3.3-7.2°Brix and vitamin C 4.8-44.1 mL/100g; water content 76.25-84.52% (wb), ash content 6.55-7.13% (db), fat content 0.20-1.65% (db), protein content 2.67-9.63% (db), and carbohydrate 63.7-70.25% (db). The content of TSS, vitamin C, protein, and carbohydrate showed significant differences between fruit.

Abstract

Enzymatic browning reaction in pandan tikar (Pandanus tectorius Park.) fruit flour (PTF) is a major problem, which can be inhibited by enzyme inactivation. This study aims to determine the effect of various enzymatic browning prevention methods on the physicochemical characteristics of PTF flour. The research method used was a completely randomized design with 4 treatments, namely (a) control (no treatment); (b) blanching (steaming at 80˚C, 3 min); (c) citric acid soaking (0.5% citric acid soaking, 20 minutes) and (d) combination (0.5% citric acid soaking 20 minutes and blanching at 80˚C 3 min). The results showed that all enzymatic browning prevention treatments had a significant effect on the physicochemical properties of PTF flour, namely the L value (brightness), a value (redness), b value (yellowness), gelatinization temperature, proximate content, crude fiber content, and total carotenoids of PTF flour. Prevention of enzymatic browning with blanching treatment can produce PTF flour with dark yellow color, L value 71.12, a value 5.98, b value 46.69, moisture content 9.91% (wb), ash 5.6% (db), fat 3.52% (db), protein 7.47% (db), carbohydrates 83.40% (db), crude fiber 15.49% (db), and total carotenoids 325 mg/Kg (db). The blanching method effectively inhibits enzymatic browning, retains carotenoid content, and produces a distinctive dark yellow color in PTF flour. However, the combination method can also prevent browning and produce a brighter flour color (closer to the natural fruit color).
