# PHASE 3 COMPLETION SUMMARY: Comprehensive Input Validation ✅
|
|
|
|
**Status:** ✅ COMPLETE - Minat, Cita-Cita, dan Prestasi benar-benar diperhatikan
|
|
|
|
**Request:** "untuk minat, cita cita dan prestasi bener2 diperhatikan juga inputannya"
|
|
|
|
---
|
|
|
|
## 📝 Implementation Summary
|
|
|
|
### 1. **Enhanced Input Validation** ✅
|
|
- **Minat**: `required|string|min:3|max:255`
|
|
- **Cita-cita**: `required|string|min:3|max:255`
|
|
- **Prestasi**: `nullable|string|min:3|max:255` (when filled)
|
|
- **Preferensi Studi**: `required|string|in:[5 valid values]`
|
|
- **Custom error messages** untuk context-specific feedback
|
|
|
|
**File:** `app/Http/Controllers/RekomendasiController.php` Lines 126-168
|
|
|
|
---
|
|
|
|
### 2. **Improved Processing Pipeline** ✅
|
|
Each criterion now goes through:
|
|
1. **Trim & Lowercase** → Normalize whitespace
|
|
2. **Validate Length** → Min 3 characters (pre-processing check)
|
|
3. **Normalize Text** → Simple stemming (e.g., programmer→programming)
|
|
4. **Map to Categories** → Coverage-based scoring
|
|
5. **Audit Logging** → Track all processing steps
|
|
6. **Score per Jurusan** → Use keyword coverage
|
|
|
|
**File:** `app/Http/Controllers/RekomendasiController.php` Lines 188-253
|
|
|
|
**Improvements:**
|
|
- Early validation before processing
|
|
- Detailed audit trail for debugging
|
|
- Coverage-based scoring (not binary matching)
|
|
|

|
|
|
|
### 3. **Enhanced Explanation Generation** ✅
|
|
Explanations now include **ACTUAL INPUT VALUES**:
|
|
|
|
**Minat Explanation:**
|
|
```
|
|
"✅ Minat Anda (Logika & Komputer) sangat sesuai dan cocok dengan
|
|
fokus kurikulum Teknologi Informasi. Anda akan mempelajari
|
|
hal-hal yang Anda sukai."
|
|
```
|
|
→ Shows: `($kategoriMinat)` with actual mapped category
|
|
|
|
**Cita-cita Explanation:**
|
|
```
|
|
"✅ Cita-cita karir Anda sangat sesuai dan aligned dengan standar
|
|
lulusan Teknologi Informasi. Jurusan ini secara langsung
|
|
mempersiapkan Anda untuk mencapai cita-cita tersebut."
|
|
```
|
|
→ Shows: Career alignment based on mapped category
|
|
|
|
**Prestasi Explanation (NEW):**
|
|
```
|
|
"✅ Prestasi Anda (TINGGI): \"juara 1 kompetisi coding\" sangat
|
|
relevan dengan Teknologi Informasi. Ini menunjukkan Anda
|
|
memiliki dedication dan capability."
|
|
```
|
|
→ Shows: `($labelLevel[$levelPrestasi]): \"$rawPrestasi\"`
|
|
→ Displays: ACTUAL PRESTASI TEXT + level + relevance
|
|
|
|
**File:** `app/Http/Controllers/RekomendasiController.php` Lines 32-103
|
|
|
|
---
|
|
|
|
### 4. **Improved Keyword Scoring with Logging** ✅
|
|
```php
|
|
private function scoreKeywordLikelihood(string $text, array $keywords, float $matchProb): float
|
|
{
|
|
if (empty($keywords)) {
|
|
return 0.50;
|
|
}
|
|
|
|
$coverage = $this->keywordCoverage($text, $keywords);
|
|
|
|
// Log untuk debugging ← NEW
|
|
if ($coverage > 0) {
|
|
\Log::debug('Keyword Coverage', [
|
|
'text' => $text,
|
|
'keywords_count' => count($keywords),
|
|
'coverage' => $coverage,
|
|
'match_prob' => $matchProb,
|
|
]);
|
|
}
|
|
|
|
$likelihood = 0.20 + ($coverage * ($matchProb - 0.20));
|
|
return max(0.05, min(0.98, $likelihood));
|
|
}
|
|
```
|
|
|
|
**File:** `app/Http/Controllers/RekomendasiController.php` Lines 621-642
