Abstrak: This study aims to analyze some aspects of cichlid fish reproduction (tilapia, oscar, and goldsoum) in reservoir Cirata. This research was done from February to July 2012. Fish samples obtained using gillnet in reservoir Cirata. Analysis ware done to determine fish abundance, diversity, evenness and fish dominance, relation between length and weight, condition factor sex ratio, gonad maturity, gonad somatic index, fecundity, and oocyte diameter. Cichlid fish ware 357 individual consisted of tilapia 166 individuals (46.49%), oscar 106 individuals (29.69%), and goldsom 85 individuals (23.80%). Amount of tilapia and oscar were abundant in maleber station, as for goldsoum were abundant in Tegal Datar station. The highest diversity (H’) is in Maleber station (2.15). The highest spesies evenness (E) was in DAM station (0.79) and the highest species dominanc was in Maleber station (0.84). Tilapia, oscar and goldsoum growth pattern are isometric. The highest condition factor for tilapia was in Februari 2012; the highhest condition factor for oscar and goldsoum was in May 2012. During the study, sex ratio (male:female) of tilapia ranged from 1.0:0.5 to 1.0:1.6, oscar from 1.0:1.3 to 1.0:0, and goldsom from 1.0:0 to 1.0:1.8 (test "chi-squere" at 0.05 significance level). First mature gonad of male and female tilapia was 209 mm and 179 mm, oskar 144 mm and 141 mm, and goldsoum 146 mm and 136 mm. Based on the level of maturity of gonads and gonad somatic index, tilapia had spawning peaks in May and July 2012, oscar and goldsoum had spawning peaks in July 2012. Fecundity of tilapia ranged from 1636 to 5068 eggs, oscar ranged from 1241 to 2757 eggs, and goldsom ranged from 1914 to 4003 eggs. Oocyte diameter of tilapia was 0.4-4.36 mm, oskar was 0.63-2.39 mm dan goldsoum was 0.25-2.45 mm. Based on the oocyte diameter distribution, the type of spawning tilapia, oscar and goldsoum was a partial spawning.

Abstrak: Fish occupy various forms of aquatic ecosystems such as marine, brackish and freshwater. Around 43% from the total number of all fish species, occupying freshwater. Reservoir construction cause alteration of topography and hydrology of natural aquatic. Topographical altaration of relate to the diversity of species. Cirata Reservoir is the main reservoirs in Indonesia, formed from the damming of the Citarum River. The number of indigenous fish species in the Citarum river before damming more than 20 species. The study found 16 fish species, with nine indigenous species, are; Barbonymus balleroides, Rasbora argyrotaenia, Osteochilus vittatus, Mystacoleucus marginatus, Hampala macrolepidota, Hemibagrus nemurus, Mystus nigriceps, Oxyleotris marmorata, Parambasis siamensis, as well as seven non-indigenous species are; Cyprinus carpio, Oreochromis niloticus, Hemichromis elongatus, Amphilopus citrinellus, Chanos chanos, Colossoma macropomum, Hypostomus plecostomus. The indigenous fish species that not found in the previous study is Barbonymus gonionotus, Puntius binotatus, and Chana striata. The reduced number of individuals and species of indigenous fish species associated with be lost of food sources, cause altaration of habitat. Although, competition with the non-indigenous species benefit the same food. Highest number of individuals and species found in location 3, whereas the lowest number of individuals at location 4 and the number of species at location 5. O. niloticus has the highest relative abundance and distribution. Value of environmental factors still suitable for the fish life.

Abstrak: Madu iilerupakan sumber karbohidrat yang komponen utamanya adalah gula berbentuk monosakarida yaitu levulosa dan dekstrosa. Madu bersifat higroskopis yaitu inenyerap air sehingga dapat menyebabkan kerusakan pada madu berupa fermentasi. Salah satu cara mengawetkan madu adalah pengeringan karena pengeringan dapat menghilangltan sebagian besar air dari madu. Pengeringan juga dapat mempermudah penanganan madu seperti pengemasan, penyimpanan maupun pengangkutannya.
