Kondisi geografis Kabupaten Minahasa merupakan pegunungan dan perbukitan, jalan utama sebagai sarana akses transportasi yang menghubungan daerah bagian selatan dengan ibukota Provinsi Manado berada di lereng-lereng pegunungan ini. Telah terjadi longsor di beberapa tempat dan menutupi jalan utama. Salah satu faktor penyebab longsoran yang sangat berpengaruh adalah bidang gelincir atau bidang geser. Guna mengantisipasi terjadinya bencana tanah longsor maka sangat penting untuk dilakukan eksplorasi geolistrik untuk inventarisasi data dan informasi potensi terjadinya bencana tanah longsor. Telah dilakukan eksplorasi untuk mengetahui potensi tanah longsor dengan menginvestigasi keberadaan bidang gelincir di Jalan Manado Tomohon. Eksplorasi menggunakan metode geolistrik resistivitas konfigurasi dipol-dipol. Pengukuran dilakukan menggunakan resistivitymeter MAE X612 EM pada 4 lintasan, lintasan 1-4 menggunakan 24 elektroda dan spasi 10 m dengan panjang lintasan 240 m. Data pengukuran diolah menggunakan software RES2DINV, hasil pengolahan berupa tampang lintang resistivitas 2 dimensi. Bidang gelincir diidentifikasi dengan resistivitas (30 - 215) Ωm, yang merupakan lapisan lempung pasiran. Bidang gelincir ditemukan pada semua lintasan, pada lintasan 1, 3 dan 4 terdapat 2 lapisan dengan kedalaman sampai 23 m. Lintasan 2 bidang gelincir teridentifikasi tersebar pada 3 lokasi dengan kedalaman mencapai 20 m.The geographical conditions of Minahasa Regency are mountains and hills, the main road as a means of transportation access that connects the southern region with the capital of Manado Province on these mountain slopes. Landslides have occurred in several places and covered the main road. One of the most influential factors for landslides is the slip surface or shear surface. To anticipate landslides, it is very important to explore geoelectricity for an inventory of data and information on potential landslides. Exploration has been carried out to determine the potential of landslides by investigating the existence of slip surface on Jalan Manado Tomohon. Exploration using geoelectric resistivity method dipole-dipole configuration. Measurements were made using MAE X612 EM resistivitymeter on 4 lines, line 1-4 using 24 electrodes and 10 m spacing with 240 m line length. Measurement data is processed using RES2DINV software, the results of processing are 2-dimensional resistivity crossection. The slip surface is identified by resistivity (30 - 215) Ωm, which is a layer of sandy clay. The slip surface is found on all lines, on lines 1, 3 and 4 there are 2 layers with a depth of up to 23 m. Slip surface at line 2 are identified spreading over 3 locations with depths reaching 20 m.

This study aimed to identify the bacterial disease in cultured eel elvers (Anguilla marmorata). The samples used for this study were taken from the Tatelu Freshwater Aquaculture Center. The samples taken were elvers (juvenile life stage of A. marmorata) which showed clinical symptoms of bacterial infection such as bleeding in the chest, abdomen, and the base of the fin, passive movement, weakness, and loss of balance of the body, loss of appetite, some wounds on back fin, chest, and tail, and the body was not slippery/shiny. Three elvers with the size of 4-6 cm, and weigh about 0.2 g were taken as samples. The organ chosen to be targeted for isolation was head kidney. Each sample was isolated twice as replicates and streaked on Triptic Soy Agar (TSA) medium. First replicates were identified in the Tatelu Health Lab of Freshwater Aquaculture, and the second replicates were identified in North Sulawesi Provincial Health Lab. Bacterial identification was done through a series of observations and morphology of bacterial colonies through gram stain, followed by biochemical tests through oxidase test, catalase test, Triple Sugar Iron Agar (TSIA) test, H2S production test, motility test, O/F test, and Simmons Citrate Agar (SCA) test. Water quality parameters that were measured included temperature, disolve oxygen, pH, and ammonia. Based on identification of bacteria in cultured elvers in Tatelu Freshwater Aquaculture Center, the elver samples had been infected with bacterial Aeromonas hydrophila.

The objective of research was to isolate the probiotic bacteria from intestine of carp. Isolation was performed by weighing 1 g of intestine, crushed and inserted in a reaction tube containing 9 mL of NaCl then centrifuged. Supernatant was taken and spread over the agar medium by scatter method. The bacteria-stocked medium was then incubated in an incubator at 28°C for 24-48 hours. The growing colonies were re-isolated on the agar medium to obtain pure colonies. The bacteria were then identified by morphological observation, resulting pigment and gram staining. Five nile tilapia (sized 8 – 10 cm) were used in pathogenicity test and placed in the aquarium. Fish were injected with 0.2 ml of Lactobacillus solution containing 1x107 CFU/mL via intraperitoneal injection. The results showed that the bacteria Lactobacillus sp had rod-shaped characteristics, white pigment and gram positive and not pathogenic, which means it can be used as probiotic for aquaculture.Keywords : Lactobacillus sp, carp, probiotic, pathogenicity test

Published: July 2019

Este artículo estudia el Tratado Hipocrático sobre Aires, Aguas y Lugares escrito por Hipócrates. Se analiza la influencia que ejerce el ambiente en la conducta del individuo, donde el médico hipocrático presta atención no solo al cuerpo del enfermo, sino a todo el universo cósmico: tierra, agua, clima, estaciones del año y vientos. Se estudia la visión pronostica de la medicina hipocrática, basada en el conocimiento racional de la enfermedad y la relación entre diagnóstico y pronóstico. Finalmente, se analiza la influencia de la teoría antropológica cuando estudia los patrones culturales de la gente, las formas de pensar y actuar, las costumbres y el carácter del individuo, factor que debe ser tomado en cuenta por el médico hipocrático.
