Abstract

Development of agribusiness of oil palm represents one of needed steps as activity of development of plantation sub-sector  in  order  to  improve  agricultural  sector  revitalization.  Plantation  of  oil  palm  in  this  time  has  expanded  not  only conducted by state companies, but also by private sector and people. In general, development of agribusiness of oil palm still has a good prospect, evaluated from price, product development and exporting. Internally, agribusiness development of oil palm  supported  by  farm  availability  and  productivity  potency  have  progressively  improved  and  expanding  through downstream industry. Land suitability analysis in sub district of Wita Ponda and Bumi Raya district of Morowali represent effort which in line with above mentioned opportunity. The effort aims to develop agribusiness of oil palm in rural to speed up rural economic activities, create employment, improve prosperity of society. Result of land suitability analysis gave picture that there were 3 (three) classes according to the land suitability: (i) Very suitable class which cover 75 % of total area, equal to 15.000 ha, (ii) Less suitable class which cover 15 % of total area, equal to 3.000 ha, and (iii) Non suitable class which cover 10 % of total area, equal to 2.000 ha. Thereby, the regions of sub district of Wita Ponda and Bumi Raya still have sufficient area for the development of plantation of oil palm.

Abstract

Evaluation  of  metabolically  energy  of  three  agricultural  by-products  has  been  conducted  on  laying  hens.  The purpose of study was to calculate and to compare the energy values of onion hay, tofu waste and bananas skin. Twelve laying hens were randomly allocated to one out of three types of feeds.  About 50 g of powder form of feeds were forced fed to the experimental hens.  The results indicate that the gross energy varied within the tested feeds. The highest values of apparent metabolically energy (AME) and true metabolically energy (TME) were achieved by tofu waste, while the energy (AME and TME) values of onion hay were higher than those values in bananas skin. The values of TME were 10.04, 11.88 and 9.58 MJ/kg for onion hay, tofu waste and bananas skin, respectively.  It is concluded that the by-product feeds are still having metabolically energy as feeds sources for raising chickens, particularly laying hen.

Abstract

The aim of the research was to identify the influences of the number of hosts and the density of parasitoid on the behavior of selfsuperparasitism at Trichogramma chilotraeae. The behavior of selfsuperparasitism was studied by examining the percentage of selfsuperparasitism as affected by the variability of host number (3, 6, 12, 24 and 48) exposed to 1 and 2 female parasitoids. A descriptive analysis was conducted in order to identify an ovipositioning sequence. The results indicated that the number of hosts significantly affected the  selfsuperparasitism percentage in the exposing treatments 1 and 2. The percentage of selfsuperparasitism was positively correlated with the ratio of the host number and the female parasitoid density. The tendency of the selfsuperparasitism behavior occurred in the early stage of ovipositioning.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh keragaman spesies, ukuran dan biomassa kumbang koprofagus dalam merombak  kotoran  hewan  dan  meningkatkan  kesuburan  tanah.    Percobaan  dilakukan  menggunakan  Rancangan  Acak  Lengkap dengan  perlakuan    jumlah  dan  panjang  tubuh  spesies  kumbang  koprofagus.  Peubah  tergantung  yang  diamati  adalah  persentase kotoran yang terdekomposisi dan kadar bahan organik serta N,P,K total tanah sebagai indikator kesuburan tanah. Hasil penelitian menunjukkan bahwa persentase kotoran hewan yang terdekomposisi lebih dipengaruhi oleh ukuran dan biomassa kumbang yang terlibat dibandingkan dengan jumlah spesies. Persentase kotoran yang terdekomposisi berkorelasi positif dengan ukuran kumbang koprofagus. Kadar N,P,K total tanah meningkat mengikuti jumlah kotoran hewan yang terdekomposisi yang mengindikasikan bahwa aktifitas perombakan kotoran hewan oleh kumbang koprofagus berpengaruh positif terhadap kesuburan tanah.
