Abstract

Sari et al. 2012. Study on the Biological Characteristics of Pegagan Duck. JLSO 1(2):170-176. Pegagan duck is one of the local genetic  and biodiversity resources in South Sumatera which needs to be conserved and developed. So far, scientific data of Pegagan duck as a biodiversity resource were relatively limited compared to other local ducks. The aim of this experiment was to investigate and identify egg variability of Pegagan duck. This experiment started by collecting 500 Pegagan?s egg from three districts, namely Tanjung Raja, Inderalaya and Pemulutan, Ogan Ilir Regency, Sumatera Selatan. Collected eggs were cleaned with lysol 2.5% prior to putting into the hatching machine. During hatching process, the eggs were rolled up and down from the 3th d until the 25th d. Egg candling was done three times: day 5, day 13 and day 25. The results showed that initial weight of parent (G0) male and female Pegagan duck was 36.87 g and 36.73 g, respectively. Meanwhile,  F1 generation was 36.90 g for male and 37.09 g for female. The growth pattern between male and female duck was relatively the same. Growth curve which showed the relationship between body weight and age of duck formed a sigmoid curve. The growth differences between male and female duck occured at the 5th week. Body weight of male duck was  higher than female duck. The highest body weight found at the  inflexion point for both male and female duck for parent (G0) was at the 4th week and for F1 was at the 5th week.  At the first laying, the body weight of Pegagan duck for parent (G0) reached 1541.17±132.19 g, whereas for F1 reached 1605.34±167.19 g. Parent (G0) and F1 of Pegagan duck layed at the average age of 153 and 154 d, wherein 30% layed at the age of < 151 d and 60% at the age of 151-170 d.These results were expectedly become database and guidance for the conservation and sustainable development of pegagan duck.

Abstract

Firmansyah et al. 2012. Suitability of Tidal Swamp for Rubber Plantation in Three Villages of Ex Rice Mega Project, Pulang Pisau Regency, Central Kalimantan Province. JLSO 1(2):149-157. Since 1920, tidal swamp has been widely developed for rubber plantation. Land rehabilitation of ex Mega Rice Project has attracted local community to cultivate the land for rubber plantation. The purpose of this research was to determine land suitability classification for rubber in tidal lowland areas located in three villages (Anjir Pulpis, Jabiren, and Sigi) in Pulang Pisau Regency wherein several types of soil were found, namely Sulfaquept, Endoaquepts, Dystrudept, and Haplohemist. The results indicated that there were several limiting factors to rubber plantation in tidal lowland, i.e. rooting condition, toxicity, nutrient retention, and peat land fire hazard. Actual land suitability classification felt into not suitable (N1) except Dystrudept of Jabiren which was classified as marginally suitable (S3). Improvements to overcome these limiting factors were required up to medium-high level. Low improvement level might not enhance land suitability class. Medium improvement level enhanced marginally suitable (S3) to moderately suitable (S2). Whilst, for high management level, it could enhance moderately suitable (S2) to highly suitable (S1). However, the development of tidal lowland for rubber plantation needed support from the government, especially the costly improvement of poor drainage system.

Abstract

Pratama et al, 2018. Oil Palm Breeding Program Strategy for Suboptimal Area in PT Binasawit Makmur  . JLSO 7(1):26-36. Suboptimal areas have great potential to be used an alternative land for cultivation of oil palm.We needed superior oil palm material to be able to grow well on that land. PT. Binasawit Makmur (BSM) through the Breeding Unit has developed a strategy regarding the assembly of superior material oil palm drought resistant. Therefore, this research aimed to develop  a strategy regarding breeding program in suboptimal lands of PT Binasawit Makmur.  The strategies used were  introducing, evaluating, and selecting genetic material based on productivity components (total and weight of fresh fruit bunches/ha, extraction rate) and high increment.  In addition, the efforts have been made to obtain drought tolerant material are conducting a progeny trial (DXP Trial) on mature palm to obtain drought tolerant in the dried season. Based on the results of the progeny trial, both of parents were traced to a crossing program. Currently, the seeds of the crossing have been obtained to confirm the results of the research on the nursery scale. In the nursery trial, research will be conducted to measure the proline content, stomata and chlorophyll content. Selection in the mature palm DXP progeny trial was followed by application a molecular tool such as SSR and SNP. Through this approach, a superior genetic material in terms of productivity and also drought tolerance can be developed and therefore can be used for recombination and release of new varieties.

Abstract

The parasitic level research and description of the parasitoid species which were parasitic towards Aphis gossypii (Glover) (Hemiptera : Aphididae ) origin the agroecosystem of the lowland and highland of South Sumatra has not been reported, although this information is needed as a foundation of biological control of A. gossypii in South Sumatra. The purpose of this study was to determine the parasitic level and provide information about the description of the parasitoid which were parasitic towards A. gossypii origin the agroecosystem of the lowland and highland of South Sumatra. Survey and exploration the parasitoid which were parasitic towards A. gossypii conducted at 11 sites in South Sumatra vegetable center.  The identification of parasitoid species was conducted in the laboratory of Entomology Department of the Faculty of Agriculture University of Sriwijaya. The results showed the parasitic level of Aphidius sp. and Diaeretiella rapae was higher during the dry season in both lowland and highland compared to the parasitic level of Aphelinus sp. However, Aphelinus sp. could only spread in the lowland. The main characteristics of Aphidius sp. (Aphidiidae) has shaped antennae filiform and segmented 13. The front wings have a triangular pterostigma. D. rapae, (Aphidiidae) has shaped antennae filiform and segmented 14. The front wings has a triangular pterostigma. The hind wing has a perfect basal cells. Aphelinus sp. (Aphelinidae) has an shaped goblets antennae and eight segmented and the last segments three of the antennae enlarged or club. Marginal venation long wings, while the venation postmarginal and stigma reduction. In addition there are two species of hyperparasitoid which were found to be parasitic towards parasitoid A. gossypii, were Ooencyrtus sp. and Aphiidencyrtus sp. (Encyrtidae) especially in the lowland.
