Problem sending data to ESP8266 from Arduino

[warriornux]

Hi friend, i have a trouble about my esp8266

i'm trying the tuttorial in web here http://www.boarduino.web.id/2015/08/kontrol-relay-dengan-arduino-dan.html

i'm write the code below this, but the output display on serial monitor not same with the tuttorial
my esp8266 cant running command from arduino

    #include <SoftwareSerial.h>
    #define DEBUG true
    SoftwareSerial wifi(2,3); // RX, TX

    void setup() {
       Serial.begin(9600);
       wifi.begin(9600);

       pinMode(10,OUTPUT);
       digitalWrite(10,HIGH);
       pinMode(11,OUTPUT);
       digitalWrite(11,HIGH);
       pinMode(12,OUTPUT);
       digitalWrite(12,HIGH);
       pinMode(13,OUTPUT);
       digitalWrite(13,HIGH);

       // Reset modul
       sendCommand("AT+RST\r\n",2000,DEBUG);
       // Konfigurasikan sebagai Akses poin
       sendCommand("AT+CWMODE=3\r\n",1000,DEBUG);
       // Sesuaikan dengan SSID dan Password
       sendCommand("AT+CWJAP=\"Andy182 Network\",\"waipigratis\"\r\n",10000,DEBUG);
       // Mendapatkan IP adress
       sendCommand("AT+CIFSR\r\n",1000,DEBUG);
       // Konfigurasikan untuk multiple connection
       sendCommand("AT+CIPMUX=1\r\n",1000,DEBUG);
       // Aktifkan server pada port 80
       sendCommand("AT+CIPSERVER=1,80\r\n",1000,DEBUG);
       Serial.println("Server sudah siap!");
        }

    void loop() {
      // Cek jika ESP mengirimkan pesan
      if(wifi.available()) {

        if(wifi.find("+IPD,")) {
         delay(1000); 
         int connectionId = wifi.read()-48;     
         wifi.find("pin=");

         sendCommand(closeCommand,1000,DEBUG); 
        }
      }

       wifi.begin(115200);

People have reported that SoftwareSerial library doesn't work reliably at 115200. Set the ESP8266 baud rate to a lower value(maybe 9600 as in the example code), then try again with your SoftwareSerial baud rate set to that lower speed.

Please copy the text from the serial monitor(use code tags) instead of posting screen shots. Your second screen shot image appears very small and the text is almost unreadable until you open it full screen.
