ABSTRACT This study aims to find where the supply of fish in Duricame from, Duri City is a city with poor water conditions resulting in a lack of fish supply originating from the area itself, while people's demand for fish exceeds the supply of supplies originating from the Duri area. Therefore, to meet the needs of the community in consuming fish, the distribution of fish from outside the region was carried out so that the fish supply in the Market of Duri was able to meet the demands of the community. Data analysis using descriptive analysis, the method used in this study is the survey method, the data collected includes primary data and secondary data. Primary data is obtained from collector traders through direct interviews using prepared questionnaires, while secondary data is obtained from related agencies. Fish marketed in Denai are imported market from various regions including sea water fish supplied in the Denai market came from the Aceh region, Sibolga, TanjungBalaiKarimun, Riau Islands, and West Sumatra. While freshwater fish supplied in the Denai market come from Maninjau, TalukKuantan, Kampar, KampungPatin. The fish supplied in the Denai Market consist of sea water fish such as sarai, big fish, tuna, tuna, ray fish, gambolo fish, belida fish, baung fish, selais fish. Whereas freshwater fish consists of cork fish, tilapia, eel, gouramy fish, sepat fish, siamsepat fish, catfish, catfish and betok fish. The fish supplied in the Denai market are imported every day with amount of 5,31 tons every day.Keywords: Fish Supply, Distribution, Denai Market, Mandau District

Pengaruh ketebalan benda uji terhadap keretakan pada beban statik telah banyak dilakukan. Kajian biasanya dilakukan dengan menganggap plastisitas ujung retak, yaitu kondisi tegangan dekat ujung retak, berada pada kondisi regangan dan tegangan bidang. Tulisan ini melaporkan hasil kajian numerik dan eksperimental pengaruh kondisi tegangan pada rongga yang menyatu akibat pulsa intensitas tegangan. Durasi pulsa yang digunakan adalah 20, 40, dan 80 Î¼s. Pengamatan terhadap permukaan yang patah memperlihatkan adanya beberapa rongga di daerah inklusi dimuka ujung retak. Rongga utama tersebut terbentuk dari menyatunya rongga-rongga kecil. Hasil pengamatan juga menunjukkan bahwa lokasi rongga utama tidak dipengaruhi oleh durasi impuls, dan ukuran rongga utama akan mengecil dengan menurunnya durasi pulsa. Simulasi metode elemen hingga menunjukkan bahwa normalisasi tegangan hidrostatik di muka ujung retak tidak dapat menjelaskan hasil-hasil dari percobaan. Sebagai contoh ketangguhan retak spesimen dengan tebal 10 mm ternyata lebih kecil jika dibandingkan dengan ketangguhan retak spesimen dengan tebal 3mm. Contoh lainnya adalah daerah terbentuknya rongga yang tidak bergantung pada tebal spesimen.

An experiment to investigate the affectivity five isolat of Arbuscular Mycorrhizal Fungi (AMF) on the growth of banana (Musa sp.) obtained from tissue culture had been conducted at the Plant Biotechnology laboratory, Glasshouse, and Experimental farm of the Faculty of Agriculture Jambi University. The results showed that there were five mycorrhizal isolates that can be tested for their affectivity on banana seedlings. The growth responses of the seedlings inoculated with AMF was higher than those non-inoculated seedlings due to higher rate of nutrient uptake. Each kind of AMF possesses different level of effectiveness on banana seedling. The application of single isolate Glomus sp-1 at acclimatization time resulted that highest effectiveness.

Banana fruit is one of main product of Lampung Province. Banana is commonly utilized as raw material of banana chip production and its peel can be converted into bioethanol. The Objectives of this study were to find out the optimum treatments of hydrolysis and fermentation for producing bioetanol. Two steps, namely hydrolysis and fermentations, were carried out in this study. In the hydrolysis step, two treatments - H2SO4 consentration and hydrolysis duration – were implemented. The H2SO4 concentration treatment consisted of five level (0, 0.025, 0.050, 0.075, and 0,100 M); and the hydrolysis period treatment consisted of two level (15 dan 30 minutes). Bioethanol fermentation was carried out at room temperature for 72 hours with Saccharomyces cerevisiae as starter at concentration of 0%, 5%, 10%, and 15% (w/v). The treatments were arranged in Randomized Complete Block Design (RCBD) with three replications. Before and after hydrolysis, the cellulose, hemicellulose, and lignin contents of banana peel were determined. The reducing sugar concentrations were measured after hydrolysis, and bioethanol concentrations were measured after fermentation. The data of the cellulose, hemicellulose, lignin, reduced sugar, and bioethanol were tabulated and analyzed descriptively. The results of this study showed that the optimum treatment for hydrolysis was H2SO4 solution at a concentration of 0.050 M at 1210C for 15 minutes. The treatment yielded reduced sugar at a concentration of 11,26mg/100 mL. The optimum treatment for fermentation was a starter concentration of 10% (w/v) which produced bioethanol at a concentration of 0.03% (v/v). Keywords : banana peel, bioethanol, hydrolysis, H2SO4, reducing sugar.

PENGARUH JENIS PELARUT TERHADAP AKTIVITAS ANTIBAKTERI EKSTRAK DAGING DAN BIJI BUAH BINTARO (Cerbera manghas L.) (Effect of Solvent Types On Antibacterial Activity of Bintaro (Cerbera mangas L.) Meat and Seeds Extract) Samsul Rizal; Hartami Dewi; Tanto Pratondo Utomo

Bintaro fruit is a tropical plant that is widely grown in Indonesia, but it has not been utilized optimally. Seed of bintaro fruit contains saponin steroids and fatty acids such as palmitat, stearat, oleat, miristat, linolenat, and linoleat fatty acid. Kernel of bintaro fruit contains saponin and polifenol that are toxic for the pests and insects. Kernel and seed of bintaro fruit may contain antibacterial activity. Fatty acid content of bintrao fruit was influenced by level of its maturity, more mature contains more fatty acid. The purpose of this research is to determine the most suitable solvent to produce the best extract which has activity of anti bacteria and find out the level of anti bacteria activity which is produced from seed and kernel extracts from the bintaro fruit by using difusi agar method. This research was arranged in a Complete Randomized Block Design, two factorial with four replications. The first factor was different part of the fruit: seed and kernel. The second factor was different type of solvent: ethyl acetate, hexane and aquades. The data were analyzed using Bartlett test for homogeneity and Tuckey test for additivity. The data then were analyzed using Anova to see the differences between treatments and tested further using LSD of 5% level to determine the best treatment. The result of this research indicated that the kernel of bintaro fruit extracted with ethyl acetate produced the extract which has the highest resistant zone activity of anti bacteria (about 10,95 mm), categorized as an average activity of antibacterial, while bintaro seed extraxted with hexane has less active of antibateria (about 8,43 mm). The most sensitive bacterium againts seed extracts and kernel of bintaro was Staphylococcus aureus.Keywords : antibacteria, bintaro fruit, extraction, and organic solvents
