Temuan Kunci:

SIMAKA S1 mengadopsi arsitektur microservices berbasis React dengan pemisahan aplikasi menjadi 3 client apps terpisah: simaka-akademik, simaka-dosen, dan simaka-mhs, yang berkomunikasi dengan multiple backend APIs. Ini merupakan evolusi signifikan dari SIMAKA S2 yang menggunakan Laravel monolithic dengan Blade templating.

Aspek Arsitektur	SIMAKA S2 (Legacy)	SIMAKA S1 (Modern)
Framework Backend	Laravel 8.x (PHP 7.3-8.0) Monolith	Multiple APIs (Laravel-based) Microservices
Framework Frontend	Blade Templates + jQuery Server-side	React 17.x + SPA Client-side
Arsitektur Aplikasi	Single monolithic app	3 separate client apps + 4+ backend services
State Management	Session-based (server)	localStorage + Component State
Autentikasi	Laravel Auth + Session	API-based + localStorage tokens
Pola Komponen	N/A (Blade views)	Class Components (135+ files)
Penggunaan Hooks	N/A	Minimal (1 component with hooks)

Karakteristik Arsitektur S2:

Single Codebase: Semua fitur dalam satu aplikasi Laravel
Fat Controllers: Controllers sangat besar (20k-50k bytes) dengan logic kompleks
Server-side Rendering: Blade templates render di server
Session-based Auth: Menggunakan Laravel's built-in authentication
Direct Database Access: Eloquent ORM dengan raw queries

Contoh Controller S2 (MhsController.php):

public function viewM(Request $req){
    $tahun = ' ';
    $jurusan = ' ';
    $kelas = ' ';
    $tipe = ' ';

    if ($req->ta != '' && $req->ta != null && $req->ta != 'null') {
        $tahun = " AND mahasiswa_daftars.tahun_ajaran = '$req->ta' ";
    }
    // ... multiple if conditions
    
    $data = DB::select(DB::raw('SELECT mahasiswa_daftars.*, 
        jurusan_s.jurusan AS nm_jur, 
        mabas.tanggal_lahir, 
        kelas.nama_kelas, 
        dosens.nama_dosen 
        FROM mahasiswa_daftars 
        LEFT JOIN jurusan_s ON mahasiswa_daftars.jurusan = jurusan_s.id 
        LEFT JOIN kelas ON mahasiswa_daftars.kelas = kelas.id 
        WHERE mahasiswa_daftars.sts_del = "F" 
        '.$tahun.$kelas.$jurusan.$tipe));
    
    return response()->json($data);
}
            

Perhatian Keamanan: Raw SQL concatenation dengan variabel request tanpa proper sanitization dapat membuka SQL injection vulnerability.

# BACKEND APIs (Multiple Microservices)
- apisimakaakademik.asia.ac.id   (Main Academic API)
- apiastor.asia.ac.id            (Authentication Service)
- apimhskrs.asia.ac.id           (KRS Service)
- apiuangkrs.asia.ac.id          (Payment Service)
            

Karakteristik Arsitektur S1:

Separation of Concerns: 3 aplikasi client terpisah berdasarkan user role
API-First Design: Backend exposed sebagai RESTful APIs
Client-side Rendering: React SPA dengan dynamic rendering
Token-based Auth: API authentication dengan localStorage
Service Layer: 27+ service modules untuk business logic
Multiple API Endpoints: 4+ specialized backend services

Contoh Service Layer S1 (set-lulus/index.js):

import { sendError } from "../../../pages/akademik/settingAkademik/api/message";
import { API_AKADEMIK } from "../../Api-Services";

export async function getLulus(nim) {
  try {
    const response = await API_AKADEMIK.get("fitur/lulus?nim=" + nim);
    return response;
  } catch (err) {
    sendError(err);
  }
}

export async function postLulus(data, nim) {
  const payload = {
    ...data,
    admin: localStorage.getItem('nama'),
  };
  try {
    const response = await API_AKADEMIK.post("fitur/lulus?nim=" + nim, payload);
    return response;
  } catch (err) {
    sendError(err);
  }
}
            

Perbaikan: Proper error handling, service abstraction, dan separation of concerns membuat kode lebih maintainable.

2.3 React Component Analysis

Metric	simaka-akademik	simaka-dosen	simaka-mhs
Total JSX Files	248 files	~150 files	~100 files
Class Components	135+ components	~80 components	32+ components
Functional Components (Hooks)	1 (Agenda.jsx)	0	0

API Service Modules	27 service modules	~15 modules	~10 modules

Peringatan Technical Debt:

Predominantly Class Components: S2 menggunakan hampir 100% Class Components dengan lifecycle methods. Hanya 1 functional component dengan hooks ditemukan. Ini menunjukkan:

Code ditulis sebelum React Hooks menjadi standard (pre-2019 style)
Missed opportunity untuk code simplification dengan hooks
Potential refactoring needed untuk modernization
Lebih sulit untuk code reuse dan testing

Contoh Class Component Pattern (S1):

class DataMahasiswa extends Component {
    constructor() {
        super()
        this.state = {
            listAngkatan: [],
            listProdi: [],
            listJalur: [],
            listSiswa: [],
            listTA: [],
            listSemester: [],
            isSearched: false,
            selectedMhs: [],
            checkAll: false,
            listExport: [],
            isExportReady: false,
            formdata: {
                tgllulus: '',
                smtta_lulus: '',
                ta_lulus: '',
                semester_lulus: ''
            }
        };
        this.closeEditModal = createRef();
        this.exportExcelRef = createRef();
    }

    handleChange = (e) => {
        this.setState({
            formdata: {
                ...this.state.formdata,
                [e.target.name]: e.target.value
            }
        })
    }

    componentDidMount() {
        this.getFilter()
        this.getProdi()
    }
    // ... hundreds of lines more
}
            

Contoh Functional Component dengan Hooks (Agenda.jsx - ONLY 1!):

import React, { useState, useEffect, Fragment } from 'react';

function Agenda() {
    const [tglAgenda, setTglAgenda] = useState('');
    const [ketAgenda, setKetAgenda] = useState('');
    const [editTglAgenda, setEditTglAgenda] = useState('');
    const [editKetAgenda, setEditKetAgenda] = useState('');
    const [agendaList, setAgendaList] = useState([]);
    const [agendaId, setAgendaId] = useState('');

    const handleFormSumbit = (e) => {
        e.preventDefault();
    }

    return (
        
            {/* Component JSX */}
        
    );
}

export default Agenda;
            

📌 Insight: Hanya 1 dari 248 file menggunakan modern React hooks pattern, menunjukkan codebase belum adopt modern React best practices.

🔐 3. Implementasi Autentikasi & Keamanan

3.1 Authentication Flow Comparison

Aspect	SIMAKA S2 (Laravel Monolith)	Simaka S1 (React + API)
Auth Method	Session-based (Laravel Auth)	Token-based (Custom API)
Login Endpoint	POST /admin/check	POST apiastor.asia.ac.id/signin/simaka/akademik/ul
Credential Storage	Server-side session	localStorage (un, adm, nama)
Password Hashing	Hash::make() (bcrypt)	Backend API (tidak terlihat di client)
CSRF Protection	@csrf token di Blade	reCAPTCHA v2
Middleware	• auth:admin • preventback • guest:admin	Client-side route protection (check localStorage)
Logout Mechanism	Auth::logout() + session destroy	localStorage.clear()

3.2 Authentication Code Analysis

S1 - Laravel Authentication (AdminController.php):

function check(Request $request){
    $request->validate([
        'username' => 'required|exists:admins,username',
        'password' => 'required|min:5|max:30',
    ],[
        'username.exists' => 'Username ini tidak terdaftar'
    ]);

    $creds = array(
        "email"=> DB::table('admins')->where('username', '=', $request->username)->value('email'),
        "password"=> $request->password
    );
    
    if (Auth::guard('admin')->attempt($creds)) {
        return redirect()->route('admin.admin-dashboard');
    }else{
        return redirect()->route('admin.login')->with('fail', 'Data yang anda masukkan salah');
    }
}

function logout(){
    Auth::logout();
    return redirect('/admin/login');
}
            

S2 - React Authentication (LoginPage.jsx):

handleLogin = async (event) => {
    event.preventDefault()
    document.getElementById('btnLogin').disabled = true
    document.getElementById('btnLogin').innerHTML = 'wait  '
    
    if (this.state.captcha != "") {
        await API_ASTOR.post('signin/simaka/akademik/ul' + key_astor.baseURL, this.state)
            .then(Response =>
                this.setState({
                    filedatas: Response.data[0].filedatas,
                    idus: Response.data[0].idus,
                    res: Response.status
                })
            )
        this.ceklogin()
    } else {
        swal({
            title: "Silahkan isi captcha terlebih dahulu!",
            text: "menutup jendela...",
            icon: "warning",
            timer: 3000,
            buttons: false,
        });
    }
}

ceklogin = () => {
    if (this.state.res == 200) {
        this.props.history.push({
            pathname: '/loading',
            state: {
                idUser: this.state.idus
            }
        })
    } else {
        swal({
            title: "Login Gagal!",
            text: "Username atau Password Salah!",
            icon: "error"
        });
    }
}
            

S2 - Session Setup (Loading.jsx):

componentDidMount = async () => {
    let checkID = this.props.location.state;
    if (checkID == undefined) {
        window.location.replace('/loadingout')
    } else {
        let idUser = this.props.location.state.idUser
        const res = await API_ASTOR.get('smaka/signin/search/inview' + key_astor.baseURL + '&uid=' + idUser)
        this.setState({
            ua: res.data[0],
            un: res.data[0].usid,
            aks: res.data[0].aks,
            user_nama: res.data[0].user_nama
        })
        if (this.state.aks == 0) {
            window.location.replace('/loadingout')
        } else {
            localStorage.setItem("un", this.state.un)
            localStorage.setItem("adm", this.state.aks)
            localStorage.setItem("nama", this.state.user_nama)
            window.location.replace('/home')
        }
    }
}
            

3.3 Security Analysis

Masalah Keamanan Kritis - SIMAKA S1:

localStorage for Auth: Storing authentication data in localStorage is vulnerable to XSS attacks. SessionStorage atau HttpOnly cookies lebih aman.
No Token Expiration: Tidak ada mekanisme token expiration visible di client-side code
Plain Text Storage: User data disimpan plain text di localStorage (nama, username, akses level)
Client-side Route Protection: Route protection hanya di client-side, bisa di-bypass dengan manipulasi localStorage
No JWT: Tidak menggunakan JWT standard, custom token mechanism

Kekuatan Keamanan - SIMAKA S2:

Server-side Session: Session stored di server, lebih aman dari XSS
CSRF Protection: Built-in Laravel CSRF protection di semua forms
Password Hashing: bcrypt dengan Hash::make()
Middleware Protection: Server-side middleware untuk route protection
PreventBackHistory: Custom middleware untuk prevent cache

3.4 API Configuration

S2 - Axios API Instances (Multiple APIs):

// Api_akademik.js
import axios from 'axios'
export default axios.create({
    baseURL : process.env.REACT_APP_API_AKADEMIK_LOCAL
})

// Api_astor.js (Authentication Service)
import axios from 'axios'
export default axios.create({
    baseURL : 'apiastor.asia.ac.id/public/'
})

// Api_krs.js
import axios from 'axios'
export default axios.create({
    baseURL : process.env.REACT_APP_API_MHS_KRS
})

// Api_uangKrs.js
import axios from 'axios'
export default axios.create({
    baseURL : process.env.REACT_APP_API_UANG_KRS
})
            

Environment Variables (.env.production):

REACT_APP_API_AKADEMIK = https://service-akademik.asia.ac.id/public/
REACT_APP_API_AKADEMIK_LOCAL = https://apiakademiklocal.asia.ac.id/public/
REACT_APP_API_ASTOR = https://apiastor.asia.ac.id/public/
REACT_APP_API_MHS_KRS = https://apimhskrs.asia.ac.id/public/
REACT_APP_API_UANG_KRS = https://apiuangkrs.asia.ac.id/public/
            

Manfaat Arsitektur Microservices:

Separation of Concerns: Authentication, Academic, KRS, dan Payment services terpisah
Scalability: Setiap service dapat di-scale independen
Fault Isolation: Failure di satu service tidak crash seluruh sistem
Independent Deployment: Update service tanpa affect yang lain

🛣️ 4. Routing & State Management

4.1 Routing Architecture

S1 - Laravel Routes (web.php):

Route::prefix('admin')->name('admin.')->group(function(){
    Route::middleware(['guest:admin','preventback'])->group(function(){
        Route::view('/login', 'dashboard.admin.login')->name('login');
        Route::post('/check', [AdminController::class, 'check'])->name('check');
    });

    Route::middleware(['auth:admin','preventback'])->group(function(){
        Route::post('/logout', [AdminController::class, 'logout'])->name('logout');
        
        // Mahasiswa routes
        Route::get('/mahasiswa', [MhsController::class, 'index']);
        Route::POST('/kelas-tambah', [MhsController::class, 'tambah']);
        Route::get('/mahasiswa-view', [MhsController::class, 'viewM']);
        Route::post('/mahasiswa-tambah', [MhsController::class, 'tambahM']);
        
        // Dosen routes
        Route::get('/dosen', [DosenController::class, 'index']);
        Route::get('/dosen-view', [DosenController::class, 'view']);
        Route::post('/dosen-create', [DosenController::class, 'create']);
        
        // ... 433+ lines total
    });
});
            

S2 - React Router (MainRoutes.jsx):

class MainRoutes extends Component {
    render() {
        return (
            
        );
    }
}

S2 - Admin Routes (AdminRoutes.jsx - excerpt):

class AdminRoutes extends Component {
    render() {
        return (
            
                {/* Mahasiswa Routes */}
                
                {/* Dosen Routes */}
                
                {/* Akademik Routes */}
                
                {/* Evaluasi Routes */}
                
                {/* Rekap Routes */}
                
                {/* ... many more routes */}
            
        );
    }
}

Routing Feature	Simaka S1	Simaka S2
Router Type	Server-side (Laravel)	Client-side (React Router DOM 5.2.0)
Route Protection	Middleware (auth:admin)	Component-level checks
Parameter Passing	URL params + Request object	URL params + props.location.state
Navigation	Page reload (redirect)	SPA navigation (no reload)
Back Button	PreventBackHistory middleware	Browser history API

4.2 State Management

State Aspect	Simaka S1	Simaka S2
State Storage	Server session + Database	Component state + localStorage
State Management Library	N/A (server-side)	None (no Redux/MobX/Context)
Component State	N/A	this.state + this.setState()
Global State	Session variables	localStorage (un, adm, nama)
Data Persistence	Database-backed sessions	Browser localStorage
State Sharing	Blade @section + @yield	Props drilling

Perhatian State Management:

No Centralized State: S2 tidak menggunakan Redux, MobX, atau Context API untuk global state management
Props Drilling: Data passing antar components menggunakan props drilling yang dapat menjadi complex
localStorage Dependency: Heavy reliance pada localStorage untuk persistent data
No State Hydration: Tidak ada mechanism untuk state rehydration setelah page refresh

Rekomendasi:

Untuk aplikasi skala menengah-besar seperti Simaka, implementasi Redux atau Context API sangat direkomendasikan untuk:

Centralized state management
Easier debugging dengan Redux DevTools
Better data flow tracking
Mengurangi props drilling
State persistence strategy yang lebih baik

📋 5. Temuan Kunci & Rekomendasi

5.1 Architecture Evolution Summary

Category	S1 (Pasca - Legacy)	S2 (Modern)	Assessment
Architecture Pattern	Monolithic Laravel	Microservices (3 clients + 4+ APIs)	Major Improvement
Frontend Approach	Server-side Blade	Client-side React SPA	Modernization
Pola Komponen	N/A	Class Components (legacy style)	Needs Update
State Management	Server Session	Component + localStorage (no library)	Missing Best Practice
API Design	Minimal (mostly web routes)	API-first, multiple services	Excellent
Security	Laravel Auth (robust)	localStorage auth (vulnerable)	Concern
Code Organization	Fat Controllers	Service Layer + Modular	Better Structure
Dependency Versions	Laravel 8 (stable)	React 17 + outdated deps	Security Risk

5.2 Critical Findings

Isu Prioritas Tinggi (SIMAKA S1):

Security Vulnerability: Axios 0.21.4 has known CVE (CVE-2021-3749). Update immediately to 0.21.2+
Authentication Storage: localStorage for auth tokens is XSS vulnerable. Migrate to HttpOnly cookies atau sessionStorage with encryption
No Token Expiration: Implement token expiration dan refresh mechanism
Client-side Only Route Protection: Dapat di-bypass. Backend API harus validate setiap request

Add Redux/Context: Implement centralized state management
Error Boundaries: Add React error boundaries untuk graceful error handling
API Rate Limiting: Implement rate limiting di backend APIs
Logging & Monitoring: Setup centralized logging untuk microservices

Peningkatan Jangka Panjang (3-6 months):

React Modernization: Gradual migration dari Class Components ke Functional Components + Hooks
Update React Router: Migrate ke React Router v6
TypeScript Migration: Consider TypeScript untuk better type safety
Testing Strategy: Implement unit tests, integration tests, E2E tests
Performance Optimization: Code splitting, lazy loading, memoization
API Gateway: Consider API Gateway untuk centralized authentication & routing

5.6 Migration Strategy (S2 ke S1)

Kompleksitas Migrasi: High

Reasoning: Complete architectural change dari monolith ke microservices, server-side rendering ke SPA, dan session-based ke token-based authentication.

Recommended Approach: Phased Migration

Phase 1 - Dual Run (3-6 months):

Run S2 dan S1 parallel dengan data synchronization
Pilot S1 dengan limited user groups (e.g., 1 fakultas)
Monitor performance, bugs, dan user feedback
Fix critical issues sebelum full rollout

Phase 2 - Gradual Rollout (2-3 months):

Migrate users per fakultas/program studi
Keep S2 as fallback option
Monitor system health metrics
Provide training & support

Phase 3 - Full Migration (1 month):

Final data migration
S2 decommissioning
Post-migration support

Total Estimated Timeline: 6-10 months
