Abstract

ABSTRACT South Minahasa Regency have a topography that varied from lowland to highland. Until now there has been no research on differences in the performance of agroforestry systems of lowland and highland agroecological zones. The purposes of this study were to analyze the diversity of plant species and to estimate the biomass amount of agroforestry systems at lowland and highland agroecological zones. The research was carried out from October to December 2017 at two different agroecological zones, namely; the highland (Mokobang Village) and the lowland (Blongko Village). The results showed that there were 21 plant species at lowland having 4 plant species in average, while 30 plant species were found in the highland with 6 plant species in average. The biomass of 0.25 to 13.11 Mg ha-1 with an average of 3.47 Mg ha-1 was found at lowland, whereas the highland contained 0.34 to 98.65 Mg ha-1 with an average of 27.40 Mg ha-1 biomass. It is concluded that in South Minahasa Regency the highland agroforestry system had more plant species and had more carbon sequestration than that of lowland.Keywords : agroforestry, highland zone, lowland zone

Abstract

ABSTRACT   Strategic Environmental Assessment (SEA) can be done to ensure that the preparation of policy, planning and program (PPP)  on  spatial plan draft  of Bolaang Mongondow Regency  have included the sustainable development. The purpose of this study was (1) to asses whether the PPP have included the linkage, balance, and fairness principles. (2) to identify the environmental impact caused by implementing PPP defined in the Bolmong’s spatial plan. (3) to find out measures in mitigating  negative impacts resulting from PPP. The study was performed using quick appraisal approach by means of matrix analysis, expert judgements, secondary data, field survey, and literature. The result revealed that the score of PPP regarding linkage principle was very good (84.24%) as well as balance principle good (79.59%). The  fairness principle and SEA principle were  very good as well  which were  (83.72%),  (82.52%) respectively.  Identified nine issues of sustainable development resulted  negative and  positive impact . This study implied that mitigating  negative impacts could be achieved by integrating SEA principles to  articles that not fully considering SEA.

Abstract

ABSTRACT Infiltration and permeability are soil parameters that can be used to describe the extent of land damage caused by the mining process. In accordance with Law No. 4.of 2009 on Mineral and Coal Mining, that reclaiming mining land is obligatory for every company that manages it. This study aims to determine the rate of infiltration and permeability on the reclaimed gold mined land. The research was conducted at the gold mining location of Bakan and Lanut. Infiltration measurements were carried out on straight line transect along the foot slope to the top slope. Measurements were made at two meter distance in 5 cm depth along the transect line direction using the Guelph Permeameter. Hydraulic conductivity was calculated from infiltration data. This research revealed that reclamation has positive effect in increasing of infiltration rate and permeability. Crop dan root growth should have contributed in increasing soil organic matter, root and microbial activities, which leads to improve soil texture and soil structure.Keywords: infiltration, permeability, reclaimed
