Abstract

The  objective  of  the  study  was  to  observe  response  of  feeding Bali  cattle multi  mineral  block (MMB) as a feed supplement on the body weight gain of Bali cattle. Nine male Bali cattle aged between 1 – 1,5 years were allotted in the Randomized Block Design consisted of 3 treatments and 3 blocks of body weight.  Parameters  measured were  roughage  intake,  absolute  and  relative  body  weight  and  feed efficiency. .Result  of  this  experiment  shows  that feeding  MMB  has  influence  (  P  <  0,05  )  on  roughage intake and body weight gain ( P < 0,01 ).  Duncan multiple  range test shows that body weight gain of cattle feed treatment R 1 and R 2 was high than those had treatment R0. It can be concluded that feeding MMB as a supplement could increase body weight gain of Bali Cattle.

Abstract

The research was conducted in the Farm of Animal Husbnadry Faculty, University of Jambi using 16 indigenous local male sheep (BW 8,81  ± 0,95 kg).The objective of the research was to investigate the effect of feeding UMB and Kumpai Grass Hay on the body weight gain indigenous local male sheep. The design  of  the  experiment  was  Randomized  Block  Design  4  x  4  (4  treatments  and  4  body  weight). Parameters measured were Dry matter intake (DMI), Body weight gain (BWG) and feed efficiency. The results of the experiment showed that DMI was significantly affected by UMB (P<0.01). The average of DMI  were  224,89  ;  326,09  ;  327,80  ;  337,26  g/sheep/day  for  P0,  P3,  P1  and P2,  respectively.  BWG of sheep was also significantly affected by feeding UMB (7,14 ; 23,60 ; 30,44 ; 30,58 g/sheep/day for  PO ; P3 ;P1 ; P2, respectively). Feed Efficiency were 0,42 % , 1,20 % , 1,31% and 1,46% for P0, P3, P1 and P2, respectively, and was affected also by UMB.We can conclude that UMB in the rations can be used effectively to increase body weight gain of indigenous local sheep.

Abstract

Energy consumption forecasting, especially premium, is an integral part of energy management. Premium is a type of energy that receives government subsidy. Unfortunately, premium forecastings being performed have considerable high error resulting difficulties on reaching planned subsidy target and exploding the amount. In this study forecasting was conducted using multilinear regression (MLR) method with ten candidate predictor variables. The result shows that only four variables which are inflation, selling price disparity between pertamanx and premium, economic growth rate, and the number of car, dictate premium consumption. Analsys on the MLR model indicates that the model has a considerable low error with the mean absolute percentage error (MAPE) of 5.18%. The model has been used to predict 2013 primium consumption with 1.05% of error. The model predicted that 2013 premium consumption was 29.56 million kiloliter, while the reality was 29.26 million kiloliter.

Abstract

This  paper  discusses  the  utilization  of  mixed  integer  linear programming  (MILP)  model  to  optimize  cost for multiproject scheduling in a  machine  maker company. The  objective is to minimize total project’s penalty cost and labor cost. The model formulated shows how to achieve theobjective i.e. whether to use outsourcing or overtime to finish all projects.  The  model  of  multi-project  scheduling  was solved  by  Branch  &  Bound  algorithm coded  in  Lingo 14.0 software.  The  case  study  shows  that  if  a company  wants  to  minimize  lateness,  it  should  use  overtime instead of outsourcing, which minimize total lateness of projects by 144 days or 73.5%. Whereas, if a company wants to optimize cost, they  should  use  outsourcing  instead  of  overtime,  which  reduces total  cost  of  about  10,873,000  IDR or  28.5%. These results indicate that the model developed is applicable for optimizing multi-project scheduling.

Abstract

Masukknya retailer asing kedalam pasar penjualan bahan bakar minyak (BBM) mengakibatkan tingkat persaingan antar stasiun pengisian bahan bakar umum (SPBU) semakin tinggi. Persaingan tidak hanya antar SPBU domestik tapi juga dengan pemain baru dari luar. Dengan kondisi persaingan yang ketat tersebut, hal utama yang harus diprioritaskan oleh para retailer agar mampu bertahan, bersaing dan tetap mengusai pasar adalah memberikan layanan yang prima dan menyediakan fasilitas pendukung yang dibutuhkan konsumen sehingga dapt memberikan kepuasan pada pelanggan. Penelitian ini bertujuan mengetahui jenis dan prioritas layanan apa dan fasilitas pendukung yang mana yang harus ada pada sebuah SPBU. Penelitian dilakukan melalui survey terhadap 211 responden dan hasilnya dianalisis dengan menggunakan metode Analisa Faktor. Hasil analisis memperlihatkan bahwa variabel yang paling mempengaruhi konsumen dalam memilih SPBU di dalam kota Jakarta adalah kejelasan tanda dan petunjuk lokasi di SPBU, sedangkan untuk SPBU di luar kota adalah tata cahaya pada waktu malam hari. Adapun variabel yang tidak mempengaruhi konsumen dalam memilih SPBU adalah ketepatan ukuran meteran bahan bakar.   ABSTRACT  Nowaday national gasoline market becomes tighter with the entrance of foreign retailers to the field. Competition is not only among domestic gas stations but also between local and foreign stations. At this situation, to survive and win the competition retailers should maintain customer satisfaction through serving good service(s) and providing facilities needed. This research aims to determine which service(s) is needed and which one is not as well what facility(s) are necessary, should be available, or can be omitted. For the purpoase, a survey was conducted. Of 211 respondents participated, the results then were analyzed using Faktor Analysis method. The findings are the most important variable to choose a city gas station is the station map and legend clarity  and station light sufficiency for out of town gas station.While the most neglible variable is the station dispenser accuracy for both city and out of town gas stations.
