Abstract

The high value and economic prospects of precious metals, have not been able to cover the environmental, health and social and economic impacts. The conversion of land functions and open pit mining activities as well as the amount of sediment waste causes very significant landscape and environmental changes. This study aims to evaluate the impact of using mercury and cyanide based on the knowledge and experience of actors (miners and gold processors) and the surrounding community on the island of Lombok. Field data collection was carried out by triangulation, namely in-depth interviews with actors and the community, and secondary/reference data from related agencies, especially the health center and several related research results. Gold extraction on the island of Lombok uses two methods which are carried out in stages, namely Amalgamation with mercury in the shelling process and Cyanidation with Potassium Cyanide in the bagging process. The results of the study show that the negative impacts of the mining process are more due to land clearing and miner safety. The impact of gold extraction using mercury is long-term, so it is difficult to identify the impact. Meanwhile, the impact of the use of cyanide is directly felt and seen by the public, especially in terms of decreasing the presence and yield of fish caught in rivers and coasts.

Abstract

One group of invertebrates that live in the mangrove ecosystem is Mollusks of mainly Gastropods and Bivalves. They are associated with mangrove as life, shelter, spawning, and also as a place to get food to support the growth them. The purpose of this reaserch was to look at the effect of mangrove species and substrate type on the distribution Mollusks (Gastropods and Bivalves) in the mangrove ecosystem of Pelangan Village, district of Sekotong, west Lombok regency. This type of reaserch is descriptive explorative. Sampling was done by purposive sampling method with determine tree species, size, and substrate. Repeatation held six times each mangrove species. The results showed that there are 25 speciesd of mollusk in mangrove ecosystem, the most abundant species of gastropod in mangrove species is Clypeomorus moniliferus with a value of 6.9 ind / m2 contained in Osbornia octodonta. As for the distribution of each species of gastropods and bivalves are not affected by the mangrove species, but is influenced by environmental factors which in this case is a substrate.

Abstract

The increasing sea surface temperature could be approved CO2 levels on the coast. It has been assumed the primary productivity in the intertidal zone was to absorb CO2 from the water column for photosynthesis. In addition, the substrate floor has a potential source of CO2 from decomposers. Phytoplankton and seagrasses are the primary productivity in the intertidal zone. Both of them have chlorophyll, they maintain the CO2 as a carbon source to move the photosynthetic systems to develop the metabolism of the body's cells. The measurements were made of the leaves and rhizomes of all the seagrass species. The absorption process was clarified by measuring the growth rate, percent LOI, and percent carbon in the whole body of the Tetraselmis sp and Dunaliella sp, which were phytoplankton species isolated from seagrass ecosystems. Enhalus acoroides (Ea) had the highest carbon content.  On the other hand, Halophila ovalis and Halophila minor are the lowest carbon due to the distribution of Ea being the widest, they were found in all of the sampling areas. In addition, the factor that was supported was due to its high growth rate ability. Phytoplankton and seagrass on the coast of Sekotong Barat absorb CO2 in the water column and floor of the sediment (carbon sink). The presence of a different increase in carbon content between Tetrasemis sp and Dunaliella sp indicates, the species of phytoplankton respond differently to CO2 stress in the ocean.

Abstract

Lisong tuna (Auxis rochei) is one of high economic potential value of fish because of its abundance and often found in the fish market in Ampenan. Evaluating the impact of fishing to the growth pattern of length-weight of tuna is needed to ensure the sustainability of lisong tuna population. It is feared that the high intensity of tuna (A. rochei) fishing can cause growth disturbances and a decrease in local tuna populations. This study aimed to determine the relationship between the weight and length of lisong tuna (A. rochei) to their growth patterns in the fish market of Ampenan. Thirty individuals of lisong tuna were collected from two fish markets, Bintaro and Kebon Roek, in Ampenan. The equation of Linear Allometric Model is used to evaluate the length and weight relationship in growth patterns of lisong tuna. This study resulted in the positive allometric growth pattern of lisong tuna with slope value more than 3 (b=3.79). It indicated that the lisong tuna which were collected in Bintaro and Kebon Roek markets have a weight growth rate faster than their length growth rate. It means that the lisong tuna sold in Ampenan markets is quite fleshy and has a good growth rate.

Abstract

Development and operational activities in KEK Mandalika can increase sedimentation of waters caused by erosion of construction material activities, this have an impact on coral reef ecosystems. Coral reef ecosystems have several important roles in support life of various aquatic organisms, Damage to the coral reef ecosystem directly and indirectly, sooner or later will threaten the sustainability of the use of these resources (social economy) and the safety of the community. Observations were conducted in KEK Mandalika coastal at 6 observation points less than 10 m. The results showed that the highest percentage of live coral cover was found in Kuta Mandalika coastal at PIT 4 area (30%, damaged category, moderate status). While the lowest percentage of coverage was at PIT 5, which was 2% (damaged category, bad status). Overall the percentage of coral cover in the Kuta Mandalika area is included in the damaged category. One of the reasons is because at the lowest tide on the beach, the volume of water is very small so that many hard corals are exposed to solar radiation. This limits the types of hard corals that can grow in the intertidal zone of Mandalika coastal. Genus diversity at this location is low, ranging from 0.0782 to 0.1288. Several genera of the Nephtheidae family dominate the observation sites and form colonies of the same genus with a fairly large distribution. The average value of environmental parameter measurements in the Mandalika coastal is included in the good category for soft coral habitat and growth.

Abstract

Salah satu masalah yang dihadapi oleh petani adalah sulit mendapatkan sebuah pupuk subsidi dari pemerintah, baik dari segi pemerataan distribusi sampai jumlah yang diberikan tidak sesuai dengan luas lahan pertanian. Sementara dari segi manfaat pupuk subsidi hanya memberikan manfaat tidak terlalu berkepanjangan, karena sering menggunakan pupuk kimia membuat kualitas tanah berubah dari yang sebenarnya, apabila terlalu sering menggunakan atau terlalu banyak menggunakan pupuk berbahan kimia membuat kerusakan tanah pada lahan yang bisa mengakibatkan berkurangnya produktifitas dari sektor pertanian. Pengabdian ini bertujuan untuk memberikan pemanfaatan limbah sayuran menjadi pupuk organik cair (POC) di desa paok pampang, sukamulia, lombok timur. Berdasarkan permasalahan diatas, penulis menemukan beberapa metode dan teknologi yang dirangkum dalam program KKN antara lain pendataan, observasi dan praktik dengan tujuan memberikan solusi atas permasalahan yang ada.
