Abstract

Fly ash can be used and utilized as an adsorbent because it is cheap and effective to adsorb waste in the aquatic environment. Hg also known as Mercury is a carciogenic heavy metal and potentially threatens human health at very low concentrations. In this study, fly ash was applied as the adsorbent for Hg2+ in the form of chitosan-fly ash composite pellet and was cross-linked with glutaraldehyde in order to know how much the mass of pellets that can be used to lower the concentration of Hg2+ in solution. The results showed that the fly ash can be compositated with chitosan gel after going through the process of physical-chemical activation so that it can be formed into adsorbent pellets/granules. The optimum condition was obtained from adsorbent pellets of fly ash-chitosan composite crosslinked with glutaraldehyde after contacted with a solution containing Hg2+ with the pellet mass of 3 g.

Abstract

Forest as the financial capital for development has important roles in economic development of Kotawaringin Barat Regency. Commonly, forest is a large area of land where flora (trees) and fauna (animals) exist. It can produce woods and other products for human consumption (production function), regulate the water system for human life, prevent flooding and sea water intrusion (protection function), and preserve many species of plants and animals and ecosystem (conservation function). Economically, forest as the source of woods, rattans and other products provided foreign exchange for the country during 1980-1990; this case placed the subsector of forestry as one of the prime movers in Indonesia’s economy. The purpose of this research was to analyze the extent of the foresty’s contribution to the economic development and social welfare in Kotawaringin Barat Regency. The research methodology was conducted by: a) interview, b) observation / field surveys and c) documentation (supporting data). The results showed that the contribution of forestry subsector in the economic development and social welfare of Kotawaringin Barat reached IDR 38.6 billion in 2011.

Abstract

This research projected the citizens and water demand in 13 regencies/cities in South Kalimantan Province from 2013 to the next 20 years. The results of the project were compared with the intake capacity to meet the demand in upcoming years. In projecting the population growth, five methods were used, namely aritmethic method, geometric method, linier regression method, exponential method and logarithmic method. The most appropriate method for projecting the population growth is the method which has the minimum value of standard deviation and the correlation value close to 1. Water demand was calculated based on some factors, such as the average water demand, the maximum level of water demand, and the water demand at peak hours. The existing intake capacity was then compared with the water demand projection. In almost all PDAM (Munipical Tap Water Company) observed, the capacity of water processing installation could not fullfill the water demand at the peak hours. The adequate intake capacity of PDAM was only in Balangan regency and Banjarmasin city.

Abstract

Fusarium wilt is one of the important banana diseases that lead to low quality and quantity of banana production. The objective of this study was to examine and study the resistance of some local banana varieties to fusarium wilt. Pathogens were isolated from the weevil of kepok banana (saba banana) that showed severe symptoms of Fusarium wilt. The inoculum was prepared by propagating the pathogens on Potato Dextrose Agar (PDA) medium. Inoculation was carried out using mycelium fragment suspension (12 mg hyphae mL-1 tween 20 0.05%). The roots of the two-week Ambon banana were injured and immersed in the suspension. Pathogens were determined using Koch's postulates. The varieties tested were seven (7) local banana varieties grown in South Kalimantan. Levels of resistance were determined based on the scale of Leaf Symptom Index (LSI). The pathogens were identified as Fusarium oxysporum f.sp. cubense. The results showed that there were differences in the levels of resistance; Kepok banana (highly susceptible); yellow Ambon, Awa, Susu, Mahuli and Talas bananas (susceptible), and Manggala banana (tolerant).

Abstract

Aquaculture in Riam Kanan river receives watersupply from rivers and Riam Kanan reservoir from upstream to downstream and practices different irrigation and fertilization systems. This study was aimed to compare the plankton community structure, to find out the physicalchemical parameters associated with the abundance of plankton and the fertility of the fish-farming ponds. The research was conducted at Mandiangin Freshwater Aquaculture Center (Balai Budidaya Air Tawar – BBAT), Karang Intan (Balai Benih dan Induk Ikan Air Tawar – BB-IAT) and Cindai Alus Minapolitan area by using the observation method. Water samples were taken by composite of 6 replicates at 12 stations. The parameters measured were temperature, visibility, pH, iron, free ammonia, nitrate, phosphate, DO, BOD and plankton analysis. Data were tested statistically with cluster, Pearson correlation and regression. The result shows that there are differences in plankton community structure in the fish ponds, shown by 5 cluster groups. The abundance of phytoplankton has a significant correlation with pH, temperature, DO, and free ammonia. The abundance of zooplankton also has a significant correlation with pH, DO, BOD, and free ammonia. The seed pond at BBAT Mandiangin is eutrophically dominated by Bacillarophyta and Amoboezoa, while in BB-IAT Karang Intan and Cindai Alus are dominated by Cyanophyta and Rotifera. The inlet channel of BB-IAT Karang Intan and the broodstock pond belong to mesotrophic category, predominance by Cyanophyta, Chlorophyta and Rotifer. BBIAT Karang Intan outlet ponds, BBAT Mandiangin inlet channel and Cindai Alus inlet pond are included in the oligotrophic category, predominance by Cyanophyta and Chlorophyta. Plankton community structure of the fishfarming pond varies even with the same ecological conditions.

Abstract

One of the interactions that occur withinthe ecosystem is the interaction of mutualism. Such mutualism interactions can be modeled into mathematical models. Reddy (2011) study suggests a model of two mutually interacting species that assumes that each species can live without its mutualism partner. In fact, not all mutual species survive without their mutualism pairs. If it is assumed that the second species lives without its mutualism partner, the first species, then the natural growth rate of the second species population will decrease (the mortality rate). The purpose of this research is to explain the model of two mutually interacting species with mortality rate for the second species, to determine the equilibrium point and the type of stability, and to simulate them with several parameters. This research was done by way of literature studies. The result of this research is the model of two mutually interacting species with mortality rate for second species modeled using Nonlinear Differential Equation System. In the model, it was obtained 3 (three) points of equilibrium, with each type and type of stability investigated. Next up from the stability, model simulations were done. Based on several simulations conducted can be seen the value of parameters and initial values affect the population growth of both species. The interaction model of two mutual species will be stable if the first species survive and the second species over time will be extinct.

Abstract

This study aimed to (1) find out the water quality parameters of the river where the common carp cage cultures are located at Murung Raya Regency, either adjacent or far from the gold mine site, including water temperatures, pH, dissolved oxygen, carbon dioxide, ammonia and water clarity; (2) to compare the common carp cage culture profits in the river either adjacent or far from the gold mine sites; and (3) to determine the common carp cage culture development strategies at Murung Raya Regency. This study was carried out in Murung Raya Regency, Central Kalimantan, with the common carp cage farmers at Muara Supoi and Muara Bumban Villages, Murung Regency as the object. The collected data were primary and secondary data. The data analysis used were descriptive analysis, t statistical test, and a SWOT analysis. The results of the study showed that condition of the water where the common carp cage cultures are located at Murung Raya Regency, either adjacent or far from the gold mine sites, still in the range of the quality standards required, namely the temperature of 29.73 - 29.78oC; water clarity of 10 - 11 cm; pH of 6.58 - 6.65; dissolved oxygen of 6.11 - 6.73 mg /l; carbon dioxide of 0.02 - 0.03 mg/l; and ammonia of 0.02 mg/l, so that the common carp cage culture activities at Murung Raya Regency were still very feasible to carried on. The average profits of the common carp cage cultures, either adjacent or far from the gold mine sites, were relatively similar, with the t statistical test result showed that the profits at both locations did not differ significantly at 95% test level. The development strategy of common carp cage cultures at Murung Raya Regency was in quadrant II or S - T, namely utilizing the strengths to overcome the threats. It was implemented by establishing two alternative solutions, namely (1) by taking advantage from the fish culture development programs and supports by the government; and (2) optimized the development function of the of seed center for supplying the high-quality seeds. One of them was by utilizing the special allocation fund (Dana Alokasi Khusus - DAK) from the Ministry of Marine Affairs and Fisheries.
