Abstract

Pujiastuti et al, 2017. Production of Bacillus thuringiensis Spores in Agricultural Waste with Addition of Golden Snail Shell Powder and its Toxicity Against Spodoptera litura Fabr. (Lepidoptera: Noctuidae). JLSO 6(2):150-157.Armyworm or Spodoptera litura is an important pest on the cultivation of plants. Controlling by using biological agents such as Bacillus thuringiensis is an alternative to the use of chemical insecticides which cause a negative impact on insects and environment. B. thuringiensis-based bio insecticide can be reproduced by using agricultural waste with the addition of golden snail shell flour. The study was aimed to investigate the production of B. thuringiensis spores on agricultural waste media and the addition of golden snail shell flour and its toxicity to armyworm, as well. The research design was a completely randomized design with 10 treatments and 3 replications. Treatment were the media of agricultural waste: 50 mL coconut water, 50 mL of tofu liquid waste, 50 mL of rice wash water and mixture of three media (v/v/v, 1:1:1) with the addition of golden shell flour as much as 5 g and mineral salt of CaCl2, MgSO4, K2HPO4, KH2PO4. The results showed the production of bacterial spores ranged from 8.90x107 spores/mL to 9.51x107 spores/mL with the highest production in the mixed treatment of the three waste media (coconut water, tofu waste and rice laundry water). In this treatment the level of toxicity was 40% in larvae of armyworm. The weight of leaf feed consumed by armyworm at various treatments was ranged from 36.33 to 46.67 g/10 larvae. The addition of mashed shell flour to growth media of B. thuringiensis did not increase the number of spores.

Abstract

ABSTRAKSTUDI KOMPARASI MODEL PERHITUNGAN BIAYA PEMBANGKITAN LISTRIK TERARAS PLTN. Analisis keekonomian yang umumnya dilakukan melalui perhitungan Levelized Unit Electricity Cost (LUEC) merupakan hal yang krusial untuk dilakukan sebelum diambilnya keputusan investasi pada proyek PLTN. Terdapat beberapa model yang dapat digunakan untuk menghitung LUEC, diantaranya adalah: Model Puslitbang PT. PLN (Persero), model Mini G4ECONS dan Model Levelized Cost. Tujuan studi adalah untuk melakukan komparasi diantara ketiga model tersebut. Teknik komparasi dilakukan dengan penelusuran formula yang digunakan oleh masing-masing model dan selanjutnya diberikan contoh perhitungan LUEC PLTN SMR 2 x 100 MW menggunakan ketiga model tersebut. Hasil penelitian menunjukkan bahwa model Puslitbang PT. PLN (Persero) mempunyai kesamaan prinsip dengan model Mini G4ECONS, yaitu menggunakan Capital Recovery Factor (CRF) untuk mendiskonto biaya investasi menjadi nilai anuitas selama umur pembangkit. LUEC pada kedua model dihitung dengan membagi hasil jumlahan biaya investasi tahunan dan biaya pengoperasian PLTN dengan produksi listrik tahunan. Sedangkan model Levelized Cost berbasis pada arus kas tahunan. Total biaya tahunan maupun produksi listrik tahunan semuanya ditarik ke tahun awal konstruksi sehingga diperoleh total biaya tahunan terdiskonto dan total produksi energi tahunan terdiskonto. LUEC diperoleh dengan membagi kedua nilai terdiskonto tersebut. Perhitungan LUEC pada ketiga model menghasilkan nilai LUEC sebesar: 14,5942 cents US$/kWh pada model Puslitbang PT. PLN (Persero), 15,056 cents US$/kWh pada model Mini G4ECONS dan 14,240 cents US$/kWh pada model Levelized Cost.Kata kunci: komparasi, model perhitungan LUEC, PLTNABSTRACTCOMPARISON STUDY ON MODELS FOR CALCULATION OF NPP’s LEVELIZED UNIT ELECTRICITY COST. Economic analysis that is generally done through the calculation of Levelized Unit Electricity Cost (LUEC) is crucial to be done prior to any investment decision on the nuclear power plant (NPP) project. There are several models that can be used to calculate LUEC, which are: R&D PT. PLN (Persero) Model, Mini G4ECONS model and Levelized Cost model. This study aimed to perform a comparison between the three models. Comparison technique was  done by tracking the persamaan used for each model and then given a case of LUEC calculation for SMR NPP 2 x 100 MW using these models. The result showed that the R&D PT. PLN (Persero) Model have a common principle with Mini G4ECONS model, which use Capital Recovery Factor (CRF) to discount the investment cost which eventually become  annuity value along the life of plant. LUEC on both models is calculated by dividing the sum of the annual investment cost and the cost for operating NPP with an annual electricity production.While Levelized Cost model based on the annual cash flow. Total of annual costs and annual electricity production were discounted to the first year of construction in order to obtain the total discounted annual cost and the total discounted energy generation. LUEC was obtained by dividing both of the discounted values. LUEC calculations on the three models produce LUEC value, which are: 14.5942 cents US$/kWh for R&D PT. PLN (Persero) Model, 15.056 cents US$/kWh for Mini G4ECONs model and 14.240 cents US$/kWh for Levelized Cost model.Keywords: comparison, LUEC calculation models, NPP

Abstract

When fitting a Autoregressive (AR) model to real data, the correct model order and the model parameter often unknown. Our aim is to find estimators of the order and the parameter based on the data. In this paper the model identification and parameter estimation for AR model is posed within a Bayesian framework. Within this framework the unknown order and parameter are assumed to be distributed according to a prior distribution, which incorporates all the available information about the process. All the information concerning the order andparameter characterising the model is then contained in the posterior distribution. Obtaining the posterior model order probabilities and the posterior model parameter probabilitiesrequires integration of the resulting posterior distribution, an operation which is analytically intractable. Here stochastic simulated annealing algorithm is developed to perform therequired integration by simulating from the posterior distribution. The methods developed are evaluated in simulation studies on number of synthetic and real data sets.Keywords : simulated annealing, autoregressive, order identification, parameter estimation.

Abstract

This  article  examines  the  problem  of  determining  the  future  value  of  the  dependent variable in the distributed lagged subset model. Unlike a distributed lag model in general, which assumes that all coefficients are not zero. In a distributed lagged subset model, some coefficients may be zero. The purpose of  this  study was  to determine  the predictive value of  the dependent variable in a distributed lagged subset model. The approach used to estimate the parameters of a distributed lagged subset model is the least square method and Ck statistic. Least squares method is used to determine the estimators of the coefficient of a distributed lagged subset model. Ck Statistic is used to select the best distributed lagged subset model. Some  simulations are delivered and prove  the efficiency of  this approach. Furthermore, this approach is implemented in real economic data.  Keywords : Distributed lagged subset model, Prediction, Least square method, Ck Statistic.

Abstract

This paper addresses the problem of the signal segmentation within a hierarchical Bayesian framework by using reversible jump MCMC sampling. The signal is modelled by piecewise constant MA processes where the numbers of segments, the position of abrupt, the order and the coefficients of  the MA processes for each segment are unknown. The reversible jump MCMC algorithm is then used to generate samples distributed according to the joint posterior distribution of the unknown parameters. These samples allow to compute some interesting features of the a posterior distribution. Main advantage of the algorithm reversible jump MCMC algorithm is produce the joint estimators for the parameter and hyper parameter in hierarchical Bayesian.  The performance of the this methodology is illustrated via several simulation results.   Keywords :     Hierarchical Bayesian model, Reversible Jump MCMC methods, Signal  Segmentation, piecewise constant Moving-Average (MA) processes
