Abstract

Cassava (Manihot esculenta Crantz) is a local food that has long been cultivated and consumed by almost all people in Sikka Regency. In cultivating cassava, farmers generally still use traditional techniques so that it has not had an impact on increasing cassava production. Cassava production can be improved through several efforts, namely using superior varieties, setting planting distance, and fertilizing activities according to plant needs. This study aimed to determine the effect of planting distance and types of inorganic fertilizers on cassava production in the Sikka Regency. This research was designed using a factorial randomized block design, namely planting distance (T) and type of fertilizer (P). Each factor consists of several levels that combine six treatments, including T2P0, T2P1, T2P2, T3P0, T3P1, and T3P2. Each treatment was repeated three times to obtain 18 experimental units. Observation variables include the number of tubers per plant and tuber wet weight per plant. Observation data were analyzed using analysis of variance (ANOVA). The results showed that the addition of Urea, SP36, and NPK Phonska (complete) fertilizers could increase the wet weight of cassava at a planting distance of 2x1 m. and the planting distance of 2x1 m had a significant effect on the number of tubers/plant, and at the planting distance of 1x1 m supported by fertilization was able to increase the wet weight of tubers/plants.

Abstract

The calibration result of Tank Model on DTA SPAS Cumucang-Cimandiri by using rainfall data, evapotranspiration and land cover in 2009 shows that the determination coeffient  equal to 0,77 to aktual discharge and model output discharge. Validation results using 2014/2015 datas shows a strong relationship between the actual discharge and the model output discharge with a determination coefficient of 0,805 and generate an average daily discharge value of 1,057 m3sec-1, a maximum discharge value of 6,68 m3sec-1, and minimum discharge value of 0,072 m3sec-1. The Model show the hydrological conditions are in moderate category with KRS value of 93,2238. Based on the analysis of internal and external factors using SWOT analysis, it was found that the management strategy of DTA SPAS Cimuncang-Cimandiri was in the SO position (Quadran I).  The conservation strategy is to keep the forest area in a state of > 30% and optimize environmental funds and services to foster people's creativity to improve welfare. As an alternative strategy that can be applied to keep the DTA SPAS Cimuncang-Cimandiri remains in  good conditions  is to make efforts of soil and water conservation such as absorption wells on settlements and making terraces on rice fields. The implementation of this conservation strategy can reduce the value of KRS to obtain of 54,326.

Abstract

The Budong-Budong River is widely used for community needs, especially clean water and water sources from the Regional Drinking Water Company (PDAM), so it is necessary to maintain its water quality so that it is following its designation. This research was conducted to determine the quality of the Budong-Budong River waters, which were affected by the activities of oil palm companies in Central Mamuju. The research objective was to determine the parameter values ​​of temperature, pH, DO, BOD, COD, TSS, Fatty Oil, sediment quality, macrozoobenthos ecological index, and status Budong-Budong river water quality affected by palm oil waste. The research was conducted at five observation points, namely company outlets, IPAL, before company, after company, creeks, rivers, each with three replications. Water samples were taken using horizontal dorm vans, and sediment samples taken using Ekman Grab. The results showed that the water quality status of the Budong-Budong River at the Outlets and WWTPs exceeded the palm oil industry of wastewater quality standards, while the waters before and after the company and river bodies were categorized as lightly polluted. This is due to the high levels of organic matter and other parameters at the Outlet and WWTP that have not undergone decomposition. Generally, aquatic sediment is clay textured, while the Diversity Index value tends to be heavily polluted according to water quality criteria based on diversity, while uniformity, macrozoobenthos dominance indicates unstable, stressed, and high dominance water conditions.

Abstract

Nickel is part of mining products. Nickel can be used for various human needs, but extracting nickel ore uses an open-pit method that produces liquid waste. CV. Unaha Bakti Persada uses sediment pond method and has 1.02 ppm of Cr6+, which is still above the standard quality standard of 0.1 ppm. This phenomenon is the basis for the need for Cr6+ liquid waste treatment through the phytoremediation method. The objectives of this study were to determine (1) the toxicity of Cr6+, (2) the reproduction of water hyacinths, (3) the absorption of Cr6+, and (4) the effectiveness of the phytoremediation method. The research used phytoremediation media of water hyacinth E. crassipes and E. azurea for 12 days and the experimental design was RAL with 2 factorials, 3 treatments and 2 repetitions. The results showed signs of toxicity in water hyacinth E. crassipes from Cr6 +, such as the faster the leaves dry out, the plants rot. The propagation of the vegetative phase only occurs in water hyacinth E. azurea, which is indicated by the presence of new stems and leaves. The absorption of water hyacinth E. crassipes 0.49 ppm, E. azurea 0.92 ppm and a combination of E. crassipes and E. azurea -0.47 ppm. The effectiveness of water hyacinth E. crassipes 48.04%, E. azurea 90.02% and the combination of E. crassipes and E. azurea -8.82%

Abstract

The rate of the population growth was accompanied with the increased number of economic growth year by year in Gowa District on the KSN Mamminasata trigger the competition of using the potential land leading to the land-use conflicts. This research aims to assess the rice field land-use potential conflicts. The map of land-use, the map of spatial pattern of RTRW in Gowa District, and the agricultural land for sustainable food crops zonation map was interpreted and collated to get a general overview of potential land-use conflicts that may occur and determine potential conflicts of government regulation sector. Then interviews were conducted with farmers using a purposive sampling questionnaire method to determine their land use preferences for the land they currently manage. It is then tabulated in the form of a typology to describe the distribution of potential land use conflicts. The results showed that the existing irrigated rice fields in Gowa District spread over nine sub-districts which all are included in the KSN Mamminasata with the total area at 19,053.27 ha and the rest of 4,229.65 ha were not included in the plan of the wetland agricultural areas, yet those belong to in residential and educational areas. In addition, there was land at 2,493.26 ha included in the zonation ALSF and ARLSF. There were 17 villages which had the higher number of rice field preferences than the residential preferences. The differences from these land-use preferences can trigger into the land-use conflicts between the parties occurred.

Abstract

One of the natural characteristics of a watershed that ensures the sustainability of ecosystem services is soil. The sustainability of ecosystem services in the Kempo sub-watershed related to soil conditions tends to be in a worrying condition because the sub-watershed is classified as critical. This study aims to describe the relationship between soil characteristics and the sustainability of ecosystem services in the Kempo sub-watershed. Data were obtained from surveys, literature studies, and on-screen digitization of Google Earth images in 2010 and 2019. Modeling of causal loop diagrams using Vensim software. The results show a tendency for ecosystem disservices to occur due to deforestation, which is characterized by the dominance of the negative/balancing behavior type, compared to the positive/reinforcing type. Soil conditions tend to be less supportive of the sustainability of ecosystem services due to high deforestation and intensive monoculture land cultivation. Important changes in the system can be made by addressing deforestation as a significant influence on negative feedback on soil conditions. The CLD model can be used in the development of a framework for assessing ecosystem services and disservices both qualitatively and quantitatively, so further research needs to build dynamic system modeling using Stock Flow Diagrams (SFD).
