Kota besar, sebuah pusat atau sentral dari suatu provinsi atau daerah yang memiliki banyak aktivitas ekonomi dan gaya hidup urban yang banyak didambakan oleh banyak orang terutama yang tinggal di daerah terpencil, mereka menilai apabila dapat mengandu nasib dengan baik di pusat kota, maka hidup mereka dapat berubah kearah yang lebih baik dari sebelumnya. Dengan alasan itulah faktor urbanisasi sangat umum di kota besar. Terutama di Kota Surabaya, yang notabenenya adalah kota terbesar kedua di bumi indonesia. Dengan pergerakan urbanisasi yang masif, dan juga diikuti dengan banyaknya tenaga kerja yang tinggal di daerah lain untuk berkarir di Surabaya, terjadi lonjakn manusia yang sangat pesat terutama pada hari kerja. Banyakanya kendaraan yang menuju kearah pusat kota dan memenuhi jalan penghubung utama. Kebutuhan akan kendaraan menjadi sangat krusial. Selain kebutuhan kendaraan yang besar, kebiasaan masyarakat yang lebih menyukai penggunaan kendaraan pribadi dibandingkan dengan kendaraan umum yang telah disediakan oleh pemerintah. Mereka menilai bahwa transportasi umum kurang memadai untuk terus dapat digunakan. Maka dari itu, perlu adanya sistem yang dapat menunjang untuk menggerakan masyarakat dalam mengurangi penumpukan kendaraan dan tetap menjaga lingkungan tetap tidak dipenuhi polusi. Sistem ini akan mengaplikasikan teori Smart Mobility, salah satu aspek dari Smart City.

Perkembangan rumah sakit di Indonesia semakin meningkat, sejak tahun 2012 sampai 2018 mengalami peningkatan dengan rata – rata 5.2%. Tentunya hal tersebut memiliki dampak terhadap daya saing yang lebih kompetitif. Kebijakan pemerintah Indonesia yang mengharuskan rumah sakit bekerja sama dengan Jaminan Kesehatan Nasional (JKN) guna pemerataan pelayanan kesehatan mempengaruhi jumlah pendapatan. Faktanya asuransi BPJS Kesehatan mengalami defisit anggaran yang nilainya sangat besar. Manajement rumah sakit harus mencari strategi dan kebijakan yang tepat dalam upaya memaksimalkan pendapatan khususnya di era JKN. Pembatasan jumlah kunjungan tidak mungkin dilakukan mengingat sebagian besar pasien berasal dari peserta BPJS Kesehatan. Tujuan penelitian ini dilakukan untuk menemukan kebijakan dan solusi yang tepat bagi rumah sakit untuk mendapatkan keuntungan finasial dalam kondisi defisitnya anggaran asuransi kesehatan. Penting informasi membuat manajemen rumah sakit berupaya untuk memanfaatkan teknologi informasi sebagai media untuk merancang strategi bisnisnya, simulasi komputer seperti pemodelan sistem dinamik mempu menggambarkan dan mensimulasikan sistem secara nyata yang mengacu pada data, sehingga pemangku kepentingan dapat memprediksi kondisi yang bisa terjadi dimasa depan. Hasil penelitian menunjukkan bahwasanya dengan merubah sistem pembayaran dari Fee For Services menjadi INA - Case Base Groups dapat memberikan keuntungan lebih bagi rumah sakit, hal ini dikarenakan tarif yang ditetapkan menyesuaikan dengan tarif rumah sakit di seluruh Indonesia. Temuan lain yang perlu diperhatikan adalah piutang pihak asuransi mengalami peningkatan, tentunya hal tersebut perlu perhatian lebih, serta bisa dijadikan bahan pertimbangan untuk mengubah sistem pembayaran karena sesuai hasil simulasi dapat memaksimalkan jumlah pendapatan . Lokasi penelitian di unit rawat inap, rumah sakit islam surabaya, diharapkan dari hasil pemodelan simulasi bisa dijadikan sebagai gambaran atau acuan bagi manajemen puncak rumah sakit dalam mengambil sebuah keputusan sebagai strategi bisnis. Abstract Hospital development in Indonesia has increased, from 2012 to 2018 has increased by an average of 5.2%.. Of course this has an impact on more competitive competitiveness. Indonesian government policy that requires hospitals to work closely with the National Health Insurance (JKN) in order to equalize health services affects the amount of revenue. The fact is that BPJS Health insurance has a very large budget deficit. Hospital management must find the right strategy and policy in an effort to maximize revenue, especially in the JKN era. Limiting the number of visits is not possible considering that most patients come from BPJS Health participants. The purpose of this study was to find the right policies and solutions for hospital to obtain financial benefits in the health insurance budget deficit. Important information makes hospital management strive to utilize information technology as media for designing business strategies, computer simulations such as dynamic system modeling can describe and simulate real systems that refer to data, so that stakeholders can predict conditions that can occur in the future. The results showed that by changing the payment system from Fee For Services to INA - Case Base Groups can provide more benefits for hospital, this is because the rates set adjust to hospital rates throughout Indonesia. Another finding that needs to be considered is that the insurance receivables have increased, of course it needs more attention, and can be taken into consideration to change the payment system because according to the simulation results can maximize the amount of income. The location of research in the inpatient unit, Surabaya Islamic hospital, is expected from the results of simulation modeling can be used as an illustration or reference for top management of the hospital in making a decision as a business strategy.

Background: Commuting time is highly influenced by traffic congestion. System dynamics simulation can help identify the cause of traffic problems to improve travel time efficiency.Objective: This study aims to reduce traffic congestion and minimise commuting time efficiency using system dynamics simulation and scenarios. The developed scenarios implement the Bus Rapid Transit (BRT) and trams projects in the model.Methods: System dynamics simulation is used to analyse the transport system in Surabaya and the impact of BRT and trams project implementation in the model in order to improve commuting time and to reduce congestion.Results: From the simulation results, with the implementation of BRT and tram projects along with highway expansion, traffic congestion is predicted to decline by 24-44%. With the reduction of traffic congestion, travel time efficiency is predicted to improve by 11-28%. On the contrary, implementation of BRT and tram project without highway expansion is predicted to increase the traffic congestion by 5% in the initial year of implementation, then traffic congestion is predicted to decline by 2% in 2035.Conclusion: Based on the scenarios, transport project implementation such as BRT and trams should be accompanied with improvement of infrastructure. Further research is needed to develop a more comprehensive transportation system to capture a broader view of the problem.

Background: Some studies have shown that Return on Total Assets is a strategy to increase market share. Other studies have also shown that social media like WeChat can increase market share. However, no studies have considered Instagram engagement in increasing market share. Objective: This study aims to identify variable linkage that increases market share through a dynamic system approach in small and medium-sized enterprises (SMEs). Methods: Using a System Dynamics approach, this study presents a model simulation with a proposed increase in market share by considering Instagram features. This approach creates a Causal Loop Diagram converted into a simulated Stock Flow Diagram. The value generated from the simulation is validated with the mean comparison and % error variance formulas. Results: Instagram engagement increases market share from 0.009 to 0.018. Such engagement can be increased by posting regularly and doing more activities, such as increasing post frequency, holding contests, and maximizing all features. Conclusion: This study has successfully modeled information technology, i.e., a promotion module on social media. However, this work has not yet demonstrated how the features can gain more market share, so future research is needed.

Hospitals are an important part of the health system. This agency consists of several main services, namely Outpatient, Emergency, and Inpatient services. One type of main service that is quite complex and needs to be considered is service at inpatient installations. Regarding this inpatient service, hospitals must make a structural and functional utilization effort to be further improved by increasing the utilization of service space regarding the number of available beds. To measure the level of utilization of hospital facilities at inpatient services, hospital service indicators are needed to measure it. These indicators include BOR (Bed Ocupanccy Rate), which is the percentage of beds filled, LOS (Length of Stay), namely the average length of stay, TOI (Turn Over Interval), which is the average free time of bed, BTO (Bed Turn Over), namely the productivity of the bed. These indicators will be presented in graphical form, namely Barber Johnson Graph. From the values produced by the hospital management, later it can be used as material for planning and decision-making in determining service facility policies in the future. The purpose of this study is to make modeling with a system dynamics so that the value of the indicator can have ideal parameter values. The result of this study is that a scenario is needed to increase the number of patient visits, because patient visits are too low. This is evidenced by the value of the BOR which is less than the ideal value. In addition, the duration of patient care, day of care was influenced by the variable number of patient visits. The results of the scenario show that in 2019 to 2030 the values of BOR, LOS, TOI, and BTO were produced according to the ideal indicator value.

A consumer complaint is a consumer's right to submit a complaint about a service or product provided, or in other words, a complaint is an expression of consumer dissatisfaction either verbally or in writing caused by the loss experienced by the consumer and the non-fulfillment of the agreed agreement. The government is very aware of the various things experienced by consumers as users of goods and services. Through the presidential regulation of the Republic of Indonesia number 50 of 2017 concerning consumer protection strategies and through this regulation the relevant sectors make various efforts to improve their performance related to following up on every complaint. Non-hierarchical grouping using the k-means method is the placement of objects based on the closest group means. Through the results of data processing conducted through research on consumer submission data based on the type of complaint, it shows that there is significance in all variables of incoming complaints, completed complaints, complaints in process with a significance level (sig) less than 0.05. Therefore, there is a significant difference in the clusters formed that relate to all these variables. And in the table the largest F value is 355,957 which indicates that the complaints entered in each cluster are different. So it can be concluded that the greater the value of F, the greater the difference in cluster 1, cluster 2, cluster 3 for the variable concerned.
