Abstract

Clove (Syzigum aromaticum L.) is a native Indonesian plant originating from the Maluku Islands. Until now, cloves have become an essential commodity to support the industry and as sources of farmers' income. An increase followed the increasing area of clove cultivation in problems caused by stem borer attack (Nothopeus Hemipterus). This research aims to obtain information about the magnitude of damage intensity and the extent of stem borer attack. This research was conducted in two village areas: Alakasing village and Solongan village in Central Peling Subdistrict of Banggai Kepulauan District for three months on July 3 - 18, 2017. The observations were carried out on ten plantations owned by farmers: five farms in Alakasing village and five farms in Solongan village. Each sample plot was observed 20 sample plants so that obtained 200 sample plants, the strata of each tree is devided. The highest pest attack area (Nothopeus hemipterus) is in Alakasing Village, plot sample I of the sixth observation is 75%, and the lowest pest attack area (Nothopeus hemipterus) is plot sample V of the sixth observation. Whereas in the observation area of the Solongan Village, the highest percentage of attack area in sample V of the sixth observation is 30% and the lowest percentage of pest attack area (Nothopeus hemipterus) sample plots I and IV respectively 20%. The percentage of damage intensity caused by clove stem borer (Nothopeus hemipterus) in the Alakasing village area was 7.56%, while the percentage of damage intensity in the Solongan Village area is 3.26%.

Abstract

The Indonesian government continously strives to increase the forest resources which continue be the problem is managing community around forests. It is due to weaknesses in management the forests area, to facilitate it is needed an institution that can manage the forest areas sustainability. Through KPH, forest management is getting better and sustainable. The aim of this research is to analyze the sustainability of the forest village community management program. This research was conducted for three months from june to August 2020 in Petimbe village and Sigimpu village, Palolo district, Sigi regency. The samples in this research were 58 respondens obtained by purposive sampling method. The data analysis method was descriptive analysis. The result shows that the sustainability of the forest village community management program obtains in to 3 dimensions (a) management planning dimension with the value of 180.89 in medium category, (b) The social community dimensions with the value of 197 in moderate category, (c) implementing management activities with the value of 127.6 in the low category

Abstract

Food crops are agricultural products consumed to support our daily lives. Food plants are also a source of vitamins and minerals needed by our bodies and directly play a role in improving health. Therefore, the hygiene and safety of the food we consume is very important, not to cause health problems. Soil is an importantfactor in agriculture, as a medium to grow plants and is also a part of the cycle of heavy metals. The gold mining business is often seen as the cause of environmental damage and pollution. This research was conducted at food and secondary crops farms around Poboya, where soil and plant analysis was carried out at the Laboratory of Natural Resources and Environment, Faculty of Agriculture, Tadulako University, Palu. The research was conducted from September to November 2020. The method used was survey with field observations and laboratory analysis, gradually done through pre-survey, main survey (sampling) and laboratory analysis with tactical sampling. The results showed that mercury (Hg) concentration in the sample point 1 was 0.48 - 0.52 ppm, sample point 2 was 0.62 - 0.63 ppm, sample point 3 was 0.30 - 0.35 ppm and sample point 4 is 0.25 - 0.26 ppm. While the concentration of mercury (Hg) in food crops, namely: sample point 1 is 0.31 - 0.33 ppm, sample point 2 is 0.45 - 0.48 ppm, sample point 3 is between 0.20 - 0.24 ppm and sample point 4 around 0.09 - 0.10 ppm. This shows that the content of heavy metal mercury (Hg) in the soil around Poboya has passed the tolerable threshold. Meanwhile, the concentration of mercury (Hg) in food crops at points 1 and 2 passed the critical threshold, while sample points 3 and 4 were still below the critical threshold. The farther the distance from the processing site, the less mercury content in the soil and in food crops.

Abstract

The information of agroclimate zonation according by Oldeman and Schmidt – Ferguson, and the potential of changes has never been done before. So, the purpose of this study is to determine the potential of agroclimate zonation changes according by Oldeman and Schmidt – Ferguson in the Palu Valley Central Sulawesi. The method used in this study is by counting the number of wet and dry months based on observation and prediction data results using ANN. The results of zonation according by Oldeman and Schmidt – Ferguson show that 2 points have the potential to changes and 2 points are fixed. The zonation by Oldeman at the Stageof Palu which was originally type E5 changes to E2 and Tawaili from E5 changes to E3, then based on Schmidt – Ferguson at Stageof Palu which was originally type F changes to E and Tawaili from F changes to D. This research found that the potential for agroclimate zonation of changes according to Oldeman and Schmidt Ferguson in the upcoming period has the potential will changes towards wetness due to the increasing number of humid and wet months, and the decreasing number of dry months.

Abstract

This study aimed to determine the effect of inclusion of curcuma and red ginger flour in the diets on slaughter weight, carcass (carcass and non-carcass components), meat quality (protein and fat) and immune organs of male laying hens. The research was carried out at the Teaching Farm, Faculty of Animal Husbandry and Fisheries, Tadulako University, South Sibalaya Village, Tanambulava District, Sigi Regency. This study was conducted for 7 weeks, March 4 - April 26, 2020. The study used DOC 168 male laying hens which were reared until the age of 54 days, than weighed to obtain slaughter weights for observation the carcass, meat quality, and immunity. The treatments were designed using Completely Randomized Design (CRD) with 7 treatments and 4 replications. The treatments were: Po = 100% basal diets, P1 = 0.5% curcuma flour + 99.5% basal diets, P2 = 1% curcuma flour + 99% basal diets, P3 = 1.5% curcuma flour + 98.5 % basal diets, P4 = 0.5% red ginger flour + 99.5% basal diets, P5 = 1% red ginger flour + 99% basal diets, P6 = 1.5% red ginger flour + 98.5% basal diets. Data were analyzed using ANOVA according to the research design applied. The results were shown high significant effect (P<0.01) on slaughter weight, carcass percentage, breast carcass components, immune organs (liver) and meat quality (protein and fat), and had a significant effect (P<0, 05) on carcass components ( thighs) and non carcass components (legs). The highest slaughter weight and carcass percentage were obtained from treatment P6 (red ginger flour with a level of 1.5% in the diets). The conclusion of this research that the inclusion of curcuma and red ginger flour can be applied in the diets up to 1.5% in male laying hens feed.

The research has been conducted since Maret- December, 2019. The Variables observed are S/C, CR, and CvR these studies use descriptive and regression analysis at a 95% trust level to identify the relationship between the variable of regression equations. The result showed that the average value of S/C was 1.42, value of C/R was 56.7%, dan CvR was 51%. Regression Analysis showed variable affected in increase the population by Artificial Insemination (IB) is Service per Conception (S/C) dan Conception Rate (CR). And didn’t affect variable towards the increasing population of IB is Calving Rate (CvR), with R Square Value 60%.
