Kebijakan pengendalian inflasi memiliki dampak yang cukup baik pada perekonomian Indonesia yang tumbuh hingga 5-6 persen pada periode 2010-2016. Namun, pertumbuhan ekonomi tersebut ternyata didominasi oleh wilayah Jakarta, Bogor, Depok, Tangerang, dan Bekasi (Jabodetabek) yang menyumbang hingga 20 persen dari total PDB Indonesia. Survei Biaya Hidup (SBH) 2012 menunjukkan bahwa wilayah Jabodetabek memiliki bobot inflasi terbesar diantara seluruh wilayah di Indonesia, yakni mencapai 35 persen, sehingga dengan melakukan analisis terhadap inflasi di wilayah Jabodetabek diharapkan dapat menggambarkan keadaan inflasi secara nasional. Dalam menganalisis inflasi daerah yang berdekatan, maka aspek spasial perlu diperhitungkan dalam pemodelan. Oleh karena itu, dalam pemodelan inflasi Jabodetabek digunakan metode STARMA dan GSTARMA untuk memasukkan aspek spasial. Hasil penelitian menunjukkan model STAR (11) dengan pembobot normalisasi korelasi silang merupakan model terbaik daripada model GSTAR. Hasil ini disimpulkan dengan membandingkan rata-rata RMSE dari setiap model dan STAR (11) memiliki nilai RMSE terkecil.

Double Deficit

This paper tests the hypothesis of double deficit in Côte d'Ivoire in non-linear aid framework, using an autoregressive smooth transition model (STAR). The main results validate the hypothesis of double deficit in Côte d' Ivoire. The effect of current balance on budget balance is greater than budget balance on current balance. Moreover, the rapid effects of current account instability on fiscal balance reveal the lack of expectation by economic agents that leads to current account deterioration compared to the deterioration of budget balance.  Thus, economic policies aimed at influencing the effect on current balance would be more effective than those aimed at the effect on budget balance. In other words, Ivorian economy adopts a Keynesian performance in the event of current account shocks and performance that tend to be more or less Ricardian in presence of fiscal policy shock.

Model STAR (1;1) atau model Space Time Auto Regresi(1;1) adalah salah satu bentuk model yang melibatkan lokasi dan waktu. Model STAR(1;1) stasioner dapat digunakan untuk prakiraan observasi di suatu lokasi pada waktu mendatang berdasarkan satu waktu sebelumnya dari lokasinya sendiri dan lokasi-lokasi lain disekitarnya. Penerapan model STAR(1;1) pada data stasioner produktivitas teh menunjukkan bahwa nilai Eigen dari matriks parameter model STAR(1;1) bernilai lebih kecil dari 1. Hal ini menunjukkan bahwa parameter model STAR(1;1) untuk data produktivitas teh tersebut memenuhi syarat stasioner.

Sewer Overflow

A commercially available 3-D computational fluid dynamics (CFD) model (STAR-CD) was used to investigate capacity upgrading options for a combined sewer overflow (CSO) facility of inadequate capacity. The numerical model was verified against the data collected in two physical models. The need for verifying the CFD model was given by the complexity of the CSO facility, which comprises several interconnected tanks. The verified numerical model was then applied to analyze hydraulic conditions in the whole facility for major structural modifications with the aim of reducing or eliminating untreated overflows from the facility. Many scenarios were proposed and tested in the study and the two most promising structural modifications, scenarios 1 and 2, are presented in the paper. Both appeared to meet the design condition of increasing the facility capacity to 60 m3/s, but better performing scenario 1 would be significantly more costly to implement than scenario 2. Even though the study focused on a particular CSO facility, hydraulic conditions in the studied facility represent general flow conditions in typical CSO or stormwater settling facilities and, therefore, the numerical modeling methods used are applicable to solving a wide range of hydraulic problems encountered at similar facilities.

We investigated collisionless aspects of the early evolution of model star clusters. The effects of mass loss through stellar evolution and of a steady tidal field are modelled using N-body simulations. Our results (which depend on the assumed initial structure and the mass spectrum) agree qualitatively with those of Chernoff & Weinberg (1990), who used a Fokker-Planck model with a spherically symmetric tidal cutoff. For those systems which are disrupted, the lifetime to disruption generally exceeds that found by Chernoff & Weinberg, sometimes by as much as an order of magnitude.
