Abstract

Simulation technology has assisted project stakeholders in predicting a range of the project results in the future under risks and uncertainties. The objectives of this article are to improve a comprehensive project planning in the perspective of the project scheduling by conducting simulations for the refurbishment of crude oil tank project risks using Monte Carlo simulations. The practical approaches for simulating the risks encompassed 3 stages: risk identification, assessment, and risk analysis using the Monte Carlo simulations. The implementation of Monte Carlo simulation in the form of stochastic approach however were not new, but the application of these approaches in the area of oil industrial projects was challenging. A Free Water Knock-Out (FWKO) tank project located in Duri, Indonesia was taken as a case study. The initial FWKO project duration was set up to be 180 working days, and it was delayed (up to 140% from the initial duration of the project planning). This study conducted deep questioner surveys from 25 oil industry stakeholders. It was identified 29 risk factors have been considered as the major causes of the project delay. The risk factors were then calculated qualitatively for performing risk indexes. Based on the risk simulations (after 1000 iterations) using Monte Carlo simulations utilizing @risk application package (under uncertainties) there was found that the possibility of this project would experience delays at the range of 47 days (126%) to 80 days (144%) from the initial project planning. This simulation had also identified the most sensitive activities causing project delays. The results was presented in the form of the spider graph diagram which assisted the project main stakeholders in developing a strategic decision during project planning phase.

Abstract

The  concept  of  the  factors  that  influence  the  behavior  of  farmers  in receiving  Operasi  Pangan  Riau  Makmur  program  (OPRM)  needs  to  be  done  to determine the most significant effect on the program’s accepting. The designing of a model before the implementation of a program, is expected to minimize the unusable things in reality. Modeling analysis SEM (structural equation model) which is used in behavior  of  farmer’s  research  designed  so  as  to  find  a  suitable  model.  Three exogenous variables used in this research, the characteristics of farmers, extension of competence,  and  competence  of  the  management  of  farmer  groups.  Each  of  these exogenous variables formed by eight indicators, so it is could explain that the skills, systematic program delivery, mastery of the program, and time management, are not included  in  the  indicator  models  that  is  affecting  the  behavior  of  fa rmers  as endogenous  variables,  to  accept  or  deny  the  existence  of  the  program.  Farmer behavior  is  further  analyzed  the  suitability  of  the  model  with  the  independence  of farmers.

Abstract

The objectives of community service were to) improve the ability of Etawah breed goat breeders (PE) in feed management and milking and b) increase the ability of farmers to innovate in developing the diversification of fresh milk into functional food. The method of implementation was carried out by extension and demonstration plots on feed management by utilizing palm leaves to be used as a complete feed ingredient formulated using other feed ingredients such as agricultural waste or other agricultural industries.Based on observations during the demonstration plot it was compared with PE goats that were kept semi-intensively on the average level of ration consumption and body weight gain per day. The average body weight gain of PE goats receiving a complete ration in the form of pellets (615.50 g / head / day) is higher than the consumption rate of livestock (566.50 g / head / day) which were kept by breeders semi-intensively. The body weight gain of the demonstration plot cattle was 193.50 g/head/ day which was higher than the body weight gain of PE goats kept by breeders (54.90 g/head/day). The introduction and practice of processing milk into functional food had been carried out by processing milk into fermented drinks in the form of yogurt and kefir and their derivative products. From this activity, it can be concluded that by improving feed management and meeting the needs of livestock, milk production can increase. The improvement of farmer science and technology had a positive impact on the orientation of raising PE goats not only for savings but also as a producer of milk which was economically very high in value.

Abstract

The purpose of this research was to get the best treatment addition of microorganisms B-DECO3 as a reducing agent contamination of waste pollution palm factory with the addition of microalgae Chlorella sp. This research used a Completely Randomized Design (CRD)with 5 treatments and 3 replications. The treatment used against waste pollution palm factory was P0 (without addition of B-DECO3 microorganisms), P1 (addition 5ml/L of B-DECO3 microorganisms), P2 (addition 10 ml/L of B-DECO3 microorganisms), P3 (addition 15ml/L of B-DECO3 microorganisms), P4 (addition 20 ml/L of B-DECO3 microorganisms). The data obtained were analyzed statistically using Anova and DNMRT at 5 % level. The result showed that the addition of microorganism B-DECO3 had significant affect for COD, BOD, TSS, oil, and pH. The treatment chosen from the result of this research was the P4 treatment which had a value of COD (330,63 mg/L), BOD (94,53 mg/L), TSS (266,46 mg/L), Oil (2,50) and pH (8,64).

Abstract

Performance of agricultural extension workers is the result of the work of extensionworkers in carrying out the tasks assigned to him. The aim of this research is toanalyze how big the influence of extension characteristic, extension role, extensioncompetence, and extension motivation to agricultural extension performance and toanalyze the impact of agricultural extension performance on paddy production inSiak Regency. Data analysis method used in this research is multiple regressionanalysis. The results of analysis indicate that the characteristics of extension, therole of extension, extension and extension motivation have influenced the extensionperformance level in Siak Regency. This indicates the agricultural extension hasbeen running well and functioning as expected. As well as the influence ofagricultural extension performance level on rice production shows the level ofperformance gives influence to paddy production seen from the implementation ofextension, evaluation and reporting. Meanwhile, the level of performance in thepreparation of extension has not affected rice production.
