Respon Tanaman Selada Merah (Lactuca Sativa L.) Terhadap Larutan Hara (AB Mix ) Pada Instalasi Horizontal Sistem Hidroponik

Dedi Satriawan — 2019-10-10

This study aims to determine the response given by the red lettuce plant to the provision of nutrients in the form of nutrient solution (AB Mix) on the horizontal installation of the hydroponic system. The study was conducted on December 20, 2017 until February 16, 2018 at the PKK Gardens Education Center in Bengkulu province. Seeding process of Red Lettuce Seedlings is carried out for 14 days then transferred to a net pot at the installation in the Greenhouse. Fertilizers with the Fiora A and B Brands are dissolved to be mixed in a nutrient bath with a capacity of 3000 L with a nutrient density of 500 ppm in the Greenhouse to be distributed to the horizontal installation of the hydroponic system inside the Greenhouse. Then growth observations were carried out on 10 plant samples with parameters of leaf length, leaf width, number of leaves, stem height, and
stem diameter for 30 days. The results obtained by sample 1-10 have an average growth and development that is not much different. The maximum leaf length and leaf width parameters are in samples 2 and 3. While the highest number of leaf strands in sample 3 is 22 strands with an average of 18 strands and sample 4 has the highest stem height parameter of 3.5 cm with an average height 2.7 cm. The largest stem diameter in sample 4 is 4.1 cm with an average of 3.38 cm. The response of red lettuce after the last week showed symptoms of leaves that are less red with relatively more withered body.

Helmiyetti Helmiyetti — 2019-10-10

This study aims to determine the type of butterfly Papilionidae in the Receiver Zone of the Great Forest Park (GFP) Raja Lelo Bengkulu. The study was conducted in June- August 2017. Determination of the location of the study was conducted using purposive sampling and butterfly collection at each location using the roaming method. Butterfly collection is carried out at 08.00-10.00 WIB and continued in the afternoon at 15.00- 17.00 WIB, on sunny weather using insect nets. The butterflies obtained were taken to the Biology Laboratory of the Basic Science building, then stretched on a stretching board and dried in an oven at 40 0 C. Furthermore, the butterfly sample is identified by the butterfly identification book and grouped by Family, Genus and Species. The data obtained were analyzed descriptively. The results showed 7 species of Papilionidae butterflies, 74 individuals belonging to 4 genera. The types of butterflies obtained were Graphium agamemnon, Grapihum sarpedon, Pachliopta aristolochiae, Papilio polytes, Papilio memnon, Papilio palinurus, Troides helena.

PENGARUH MEDIA TANAM DAN NUTRISI TERHADAP PERTUMBUHAN DAN HASIL TANAMAN SELADA KEPALA RENYAH (Lactuca sativa var. capitata) SECARA HIDROPONIK

Sri Astuti — 2019-10-10

Study aims to determine the effect of planting media and nutrients on the growth and yield of crispy lettuce (Lactuca sativa var. Capitata) hydroponically and to determine the best planting media and types of nutrients on the growth and yield of crispy lettuce (Lactuca sativa) var. capitata) hydroponically. This research uses factorial experimental design in CRD. The first factor is 3 planting media (coffee husk charcoal, rice husk charcoal and rock wool). The second factor is 3 nutrients (organic, AB mix and organic + inorganic). There are 9 combinations of planting media and nutrition for the growth of crispy lettuce head planting. Each combination is randomized before being tested, to determine the order of testing. Each combination is done 3 times. The results of observations and average calculation of plant parameter data at the 4th week after transplanting showed the result that there was no effect of the planting media and nutrients on the growth and yield of lettuce. Likewise with the results of analysis of variance (ANOVA) showed that there was no real effect on plant parameters.

Hari Marta Saputra — 2019-10-10

Parasitic diseases that are often a problem in livestock but are often ignored by farmers are intestinal worms caused by gastrointestinal worms. This study aims to determine the types of internal parasites in goat feces (Capra sp.). The study was conducted in July- August 2018 at the UPTD Laboratory and Animal Health Clinic in Bengkulu Province. Samples were taken from Bengkulu City Goat Market, then observed using native and sedimentation methods. The results of observing samples from three types of goat feces with negative methods obtained negative results, while observing samples by sedimentation method obtained six genus of worm eggs, specifically Ascaris sp., Ostertagia sp., Oesophagostomum sp., Strongyloides sp., Schistosoma sp., dan Skrjabinema sp.

The purpose of this study is to find out the types of dragonflies (Odonata) found in the Klowe Bay Nature Reserve, Enggano sub-district, North Bengkulu Regency, Bengkulu Province. The study was conducted in the Klowe Bay Nature Reserve, Enggano sub-district, North Bengkulu Regency, Bengkulu Province in January 2018, which was identified in the Animal Physiology laboratory, Basic Science Biology, University of Bengkulu. by means of purposive sampling by surveying locations in accordance with dragonfly living conditions such as the presence of water and the presence of plants that are habitat for small insects that are food for dragonflies so that 2 points are determined. Dragonflies collected by exploring by swinging the net towards the dragonfly. The sample obtained is put into a killing bottle contains cotton in which the cotton has been given chloroform. The results obtained are 4 types of dragonflies with 15 individuals included in the Anisoptera sub-order. The types obtained include the Libellulidae Family, namely Orthetrum sabina, Pantala flavescens, Crocothemis Servilia, and Orthetrum glaucum.
