Abstract

The aim of this research is to identify the diversity of bacterial types and determine the prevalence value of these bacteria on the carapace of C. amboniensis from natural habitats to support the provision of data that can later be used to support captive management activities and conservation actions C. amboniensis was collected manually and 20 individuals were obtained, samples were caught in December 2019. Data from bacterial identification was then used to calculate the prevalence of bacterial diversity. The identification results showed that there were 7 types of bacteria, most of which were Gram negative bacteria. The prevalence values were then calculated to obtain the results of A. caviae (5%), C. jejuni (30%), C. freundii (15%). ), F. breve (25%), L. monocytogenes (15%), P. haemolytica type A (5%), and P. alcaligenes (5%).

Abstract

This study aims to determine the growth performance and nutritional digestibility of laying hens using curcuma and red ginger as feed additives. The research was conducted at the Teaching Farm, Faculty of Animal Husbandry and Fisheries, South Sibalaya Village, Tanambulava District. Sigi Regency, March 23 - May 03, 2020. The research design used a completely randomized design. The variables observed were growth and digestibility performance. Growth performance consisted of ration consumption, body weight gain, and ration consumption. Digestibility consists of digestibility of crude protein and crude fat. The results showed that the addition of curcuma flour at a level of 0.5% -1.5% can have a significant effect on body weight gain and crude protein digestibility (P>0.01) while the addition of red ginger at a level of 0.5% - 1.5% can have a significant effect on body weight gain, ration conversion, crude protein digestibility and crude fat digestibility (P>0.01). The conclusion from the results of the study that the performance of red ginger added at the level of 0.5%-1.5% was more effective in influencing growth and digestibility performance than that of curcuma.

Abstract

This research was conducted to determine nutrient status and soil fertility levels in Dolo District, Sigi Regency, map the soil nutrient status and soil fertility levels in Dolo District, Sigi Regency and as a reference for recommendations for land management in accordance with nutrient status and fertility levels in the three uses. different lands in Dolo District, Sigi Regency. This research was conducted in Langaleso Village and Kabobona Village, Dolo District, Sigi Regency, taking soil samples on cocoa land, deep coconut land and dry land in Dolo District, Sigi Regency. This type of research is a survey method and the data is presented descriptively. By trying to conduct observational surveys and soil sampling by purposive sampling. Soil samples were taken from 3 types of land use, namely cocoa land (K), Kelapa Dalam land (P) and dry land (T). Soil samples were taken at a depth of 0 - 20 cm and 21 - 40 cm. Where each land use is taken at two different locations, each two points of soil sampling and composited so that a total of 12 soil samples are obtained. The results of the research showed that the nutrient status that became an obstacle in soil fertility in Dolo District, Sigi Regency was Soil Reaction (pH) slightly acidic, Cation Exchange Capacity (CEC), C-organic, Nitrogen (N), Phosphorus (P), Potassium ( K) is classified as moderate, and base saturation (KB) is low so that the level of soil fertility on coconut, cocoa and dry fields in Dolo District, Sigi Regency is moderate and has unhealthy/less fertile soil quality.

Abstract

The aim of this research is to measure the intensity of wood vein disease and the level of soil fertility in areas of cocoa land affected by the disease and to determine the relationship between the level of maintenance (sanitation) of cocoa and the development of wood disease attacks. The analysis was carried out by calculating the incidence of disease and disease severity using the disease incidence and severity formula and the data was carried out using a simple variable correlation test to see the relationship between the sanitation level of cocoa plants. and the development of PPK disease. The results of disease incidence calculations show that land two (2) has the highest incidence of PPK disease at 69.33% and the lowest disease incidence is found in land four (4), namely 42.67%. Meanwhile, the highest level of PPK disease severity was found on land 2 at 29.47% and the lowest level of disease severity was found on land 4 at 13.73%. The results of the bivariate correlation test (r) show the person value correlation value r = 0.992 with a significance value (5%) = 0.008, which means that sanitation has a very close relationship with the development of wood disease.

The business feasibility of candlenut, palm sugar and sap products in Bakubakulu Village has an R/C value of more than 1, meaning that the total income is still greater than the total production costs and business activities for utilizing NTFP products. still feel the benefits. The contribution of HHBK utilization to the income of the Bakubakulu Village community is 44.61% or around Rp. 35,160,000/year. In order for the community to obtain the maximum economic benefits while providing environmental services, it is necessary to increase technical, institutional and educational capacity in managing NTFPs.

Abstract

This research aims to identify visitors' perceptions of the environmental conditions of urban forests and calculate the WTP value for efforts to maintain forest environmental conditions. Using the CVM method is a survey technique to ask respondents about the value/price they give to commodities that do not have a market price, such as environmental goods. The results obtained, Respondents' Perceptions were assessed from several aspects, namely: Cleanliness, Beauty, Comfort, Coolness and Satisfaction. With respondents' average rating being "Quite good and good" and the aspect with the highest score being Beauty and Comfort with a score of 4.17, the average WTP for urban forests is IDR. 2,818.2, with the number of respondents willing to pay 253 out of the total respondents 269 and the total WTP or income that can be generated is IDR. 273,803,792 per year. Based on the total WTP value obtained, it can be used as a reference in developing and improving environmental services that can be offered and become an attraction for the city of Palu, so that more and more people visit the Palu city forest and can enjoy it continuously.
