Judul: Jumlah dan bobot massa larva kumbang Tenebrio molitor pada media bertelur yang berbeda
Abstrak: Significance economic value of the larva of Tenebrio molitor beetle (called : mealworm) made researchers finding out methods and means to increase mealworm production. Manipulating egg laying media was one of the mean. This research was done from July up to October 2005 at Non Ruminants and Prospective Animal Division, Department of Animal Production Technology, Faculty of Animal Science, Bogor Agricultural University. The purpose of this research was to compare total and mass weight of the mealworm from four different egg laying media. The egg laying media used as the treatments were feed, cotton, dry banana leaves and rotten wood. This study used 1600 T. molitor beetles which had a day old. Completely Randomize Design was used as the experimental design with four replications for each treatment. The observed variables were total of the larva, mass weight and body weight of each larvas. The obtained data were analyzed by Analysis of Variance (ANOVA) and tested with Duncan's Multiple Range Test. The result showed that cotton was the best egg laying media compared to three other media. Total and mass weight of the mealworm at cotton media (4164,s larvas and 61,028 g) were higher than other media (feed : 3029,s larvas and 59,965 g, dry banana leaves : 1836,s larvas and 47,725 g, rotten wood : 1842,5 larvas and 44,930 g). Dry banana leaves and rotten wood media could be used by the farmer if he wants to increase body weight of each larvas. Combination of egg laying media could be taken into account such as dry banana leaves or rotten wood and feed. Key words : Tenebrio molitor, Mealworm, Egg laying media

Judul: Performa ulat tepung (Tenebrio molitor L.) pada suhu dan kelembaban yang berbeda
Abstrak: Yellow mealworm is the larval stage of Tenebrio molitor L. beetle. Nowadays, yellow mealworms are reared because of its economic value. Yellow mealworm can be used for feed and food. The growth of yellow mealworms is influenced by temperature and humidity, so a suitable combination of temperature and humidity is necessary for yellow mealworm optimal production.The research was done from July 1 5u~p t o Oktober lo* 2005 at Non Ruminants and Prospective Animals Division, Departement of Animal Production and Technology, Faculty of Animal Science, Bogor Agricultural University. The purpose of this research was to compare the yellow mealworms (Tenebrio molitor L.) growth performances at different temperature and humidity. This research used 1500 yellow mealworms aged 35 days old. The experiment used Completely Randomized Design in 2x2 factorial experiment. The first factor was temperature (29 and 31 OC) and the second factor was humidity (69% and 71%). Each treatment combination had five replicates which consisted 75 yellow mealworms. The observed variables were feed consumption, body lenght and weight gain, feed conversion based on body lenght and weight gain, and mortality. Data were analyzed by using ANOVA and tested with Least Significant Difference Test (SAS 6.12) to know the difference among the treatments. The result showed that the lower temperature (29 OC) with higher humidity (71%) gave the best growth performances for 35-65 days old yellow mealworms. Otherwise, the best growth performances for 65-75 days old yellow mealworms were at higher temperature (3 1 OC) with lower humidity (69%).

Abstrak: Perkembangan kota Jakarta dari waktu ke waktu sangatlah cepat, sehingga menyebabkan kota-kota tua banyak yang tergusur untuk dijadikan daerah baru yang lebih modern. Apabila hal tersebut tidak ditanggulangi secara dini maka keberadaan Kota Lama Jakarta akan hilang. Hal inilah yang melatar belakang untuk dilakukan tindakan perlindungan dan revitalisasi kawasan bersejarah Sunda Kalapa.
