Abstract

ABSTRACT    This research was done to study the increment of Gyrinops versteegii on lands with different levels of ground water depth, a shallow groundwater depth (45-50 cm) at A location and a deep groundwater depth (90-98 cm) at B location. This study used comparative method and purposive sampling. Variables observed were the increase in trunk diameter and free- branch heigtht of Gyrinops. The number of plant sample used was 6 (six) plants, three (3) plants for each location. The measurement of trunk diameter was done, using a measuring tape, at the base of the stem or at 30 cm from the ground. Free branch height was measured from the base of the stem up to the height of the first branch. These observations were done once a month for a year. The results showed that the growth of plants in two locations had differences in trunk diameter and free-branch height from the first month until the last month of observation. The average increments of trunk diameter and free-branch height in the B location were greater than in the A location. Keywords: increment, the ground water  level, Gyrinops versteegii

Abstract

ABSTRACT Information on agricultural machinery and equipment is required for the development of agricultural technology in Indonesia. Although Indonesia is known as an agricultural country, its agricultural technology is considered less developed compared to many other non-agricultural countries. One reason behind this is the dissemination of information regarding agricultural machinery and equipment still believed asunstructured and fragmented. Advancement in information and communication technology has made easiness for people in accessing information. Android operating system is gaining more and more popularity and its userin Indonesia is growingfast. This research aims to develop an Android based practical learning application on agricultural machinery and equipment. This research was carried out during the month of April 2015 to June 2015 and the resulted application was successfully installed in Android as a 1.8 Mb APK file format. The application was tested on CPU emulator and Andromax smartphone followed by a survey to 16 respondents using questionnaire having 10 questions in it (5 questions for application and 5 other questions for content of application). The respondents, who marked each question with 1=very disagree; 2=disagree; 3=neutral; 4=agree; 5=very agree, consist of 10 university students, 3 university lecturers, 1 representing farmer, 1 consultant in agricultural machinery and equipment, and 1 representingcommon people. Results of the test conclude that this Android application can be implemented as information media to improve awareness of public and university students regarding agricultural machinery and equipment in a quicker and a more efficient way. The application can also help disseminating information regarding agricultural machinery and equipment in a more variety way in order to support the development of agricultural technology in Indonesia.

Abstract

ABSTRACT Talawaan watershed is one of the most important watershed in North Minahasa Regency. Erossion in the Talawaan watershed results in decreasing land resource quality caused by both natural and human activities. This research aims to study the erosion hazard level in Talawaan watershed. Method to calculate erosion rate is based on USLE equation (Wischmeir and Smith, 1978) utilizing Geographic Information Systems (GIS). Result shows that the erossion hazard levels in Talawaan Watershed were “very light” 2.791,56 ha (21,49%), “light” 4.019,46 ha (30,94%), “medium” 3.127,86 ha (24,08%), “heavy” 2.521,79 ha (19,41%), and “very heavy” 528,88 ha (4,07%). Talawaan watershed has an average erosion rate of 60.53 tonnes/ha/year which is “medium” erosion hazard level. The results of this study may be used to a better management plan of Talawaan watershed.

Abstract

ABSTRACK  This research presents land cover conversions on Mount Tumpa Forest Park within the 2007-2014 period; what was converted, where it happened, and how big those conversions were. The results shows that there are six classes of land cover, namely secondary forest, teak forest, buses, farm fields, mixed plantation, and coconut plantation. That there were a variety of conversions between classes in all observed villages : (1) secondary forest to coconut plantation, mixed plantation, bushes and fields (5.90%), (2) mixed plantation to bushes (0.23%), (3) coconut plantation to mixed plantation (0.61%), (4) fields to mixed plantation, bushes and secondary forest (4.74%). Even though some areas classified as bushes and farm fields were converted into secondary forests, the conversion of secondary forests to other classes (coconut plantation, mixed 2  plantation, bushes, and fields) is bigger in comparison, thus causing a decrease of the forest area by 1.03 ha.Or  175.13 to 174.10 ha between 2007-2014.   Keywords: Forest area decrease, land cover conversion, GIS
