Abstract

The study aims to detect ground water availability at Buhias Island, Siau Timur Selatan District, Sitaro Regency. The research method used the survey method by geoelectrical instrument based on subsurface rock resistivity as a geophysical exploration results with geoelectrical method of Wenner-Schlumberger configuration. Resistivity geoelectrical method is done by injecting a flow into the earth surface, then it is measured the potential difference. This study consists of 4 tracks in which each track is made the stretch model of soil layer on subsurface of ground.  Then, the exploration results were processed using software RES2DINV to look at the data of soil layer based on the value of resistivity (2D). Interpretation result of the track 1 to 4 concluded that there is a layer of ground water. State of dominant ground water contains the saline (brackish). Location of trajectory in the basin to the lowland areas is mostly mangrove swamp vegetation. That location is the junction between the results of the runoff of rainfall water that falls down from the hills with sea water. Bedrock as a constituent of rock layer formed from marine sediments that carry minerals salts.

Abstract

ABSTRACT ECONOMIC AND ENVINONMENT STUDY ON PIG FARMING AGRIBUSINESS IN TOMOHON CITY. (CASE STUDY).This study aims to analyze the feasibility of conventional (private) and environment (externalities) investment criteria, which determine the extent of the economic feasibility of the externalities investment criteria taking into account the private costs (conventional costs) and externalities costs (environmental costs) in the pig farm agribusiness. This research was conducted in Tomohon, where the sample pig farms that have business scale criterion of < 1,000 , 1,000-5,000 , and > 5,000 heads. The analysis used the analysis of investment criteria, with the calculation of Net Present Value (NPV), Benefit Cost Ratio (BCR) and Internal Rate of Return (IRR). NPV of conven-tionally and externalities was greater than zero or positive, these results suggest that the companies have been conventionally sampled financially feasibility, as well as the investment plan of externalities. IRR conventional and externalities is greaterthan one, these results indicate that the samples with conventional and externalities investment companies are still profitable, especially if the investment is viewed in the environment, it would be beneficial as it will reduce the environmental impact. BC ratio values conventionally and externalities is greater than one, these results suggest that the externalities investment is feasible for conducting.

Abstract

EGG LAYING BEHAVIOR OF MALEO BIRD (Macrocephalon maleo) AT MUARA PUSIAN NATURAL CONSER-VATION IN BOGANI NANI WARTA-BONE NATIONAL PARK, EAST DUMO-GA DISTRICT OF BOLAANG MONGON-DOW REGENCY Bogani Nani Wartabone National Park was conservation living area of the all flora and fauna species including maleo bird (Macrocephalon maleo) as the endemic bird in Sulawesi Island. Objective of this research was to study behavioral laying egg of maleo bird, temperature and hole deep of laying egg, total visitation of maleo bird at laying egg hole places and predator threat around laying egg hole places. Research was conducted by direct observation at the maleo habitat of laying egg holes place. Data obtained were analyzed descriptively to describe the facts and phenomena occurring at the bird habitat. Results showed that bird activities before laying egg at holes included digging the laying egg hole, laying egg in the hole, heaping up egg hole, digging false egg holes. Bird activities after laying egg at holes included pause and look for feed around holes and then they flied to the forest area. The average times of laying egg were 1 to 3 hours, started from looking for area of hole, digging holes, playing around egg holes area to the end of laying egg in the hole. The averages of egg holes deep were 41.8 ± 14.28 cm and egg holes temperatures were 270 C - 340 C. Maleo birds were laying their eggs more around Tower I compared with around Tower II. Around Tower I had dense vegetation of trees used as shelter, protection place from predators, clean area from scrubs for easy digging holes of laying egg. Around Tower II, there were growing scrubs (Saccharum spontaneum) and coarse grass (Imperata cylindrical) causing unsecure and difficult digging holes by maleo birds in laying their eggs. The total visitations of maleo birds around egg holes areas were visibly observed of 28 pairs and 1 male without spouse and 9 pairs found by auditory observation. Therefore, there were 37 pairs consisted of 37 females and 38 males of maleo birds observed. The total eggs obtained during observation were 42 eggs, consisted of 2 damaged eggs and 40 hatching eggs using the artificial hatchery at study location. Key words: Behavioral laying egg, maleo bird (Macrocephalon maleo).
