# Bab 10 — Experiment Execution & Data Collection

## Dari Rencana ke Data yang Terpercaya

*Pertemuan 10 (M10) &nbsp;|&nbsp; Sub-CPMK 3.2 &nbsp;|&nbsp; CPMK03 &nbsp;|&nbsp; CPL06*

Fase: **Executing** (M9–M11) &nbsp;·&nbsp; Bagian III: Execution

**Universitas Putra Bangsa** &nbsp;|&nbsp; Fak. Sains & Teknologi &nbsp;·&nbsp; Prodi Teknik Informatika

---

## Agenda Pertemuan 10

1. Execution plan: pentingnya perencanaan sebelum eksekusi
2. Experiment Execution Pipeline
3. Mengapa multiple run wajib
4. Struktur data logging yang benar
5. Konsistensi eksekusi — sama persis setiap kali
6. Data collection protokol
7. Cognitive Traps & Studi Kasus
8. Output Praktis: Log Eksperimen + Dataset Mentah

---

## Capaian Pembelajaran

Setelah pertemuan ini, mahasiswa mampu:

- Menyusun **execution plan** yang detail sebelum menjalankan eksperimen
- Menerapkan **multiple run** dan menjelaskan alasan statistiknya
- Merancang struktur **data logging** yang komprehensif
- Memastikan **konsistensi eksekusi** di semua skenario dan run
- Menghasilkan **dataset eksperimen mentah** yang siap divalidasi

> Sub-CPMK 3.2 → Melaksanakan eksperimen dan mengumpulkan data (CPL06)

---

## Experiment Execution Pipeline

*Dari desain ke dataset yang siap dianalisis*

<div class="highlight-box">

**Design** &darr; Execution Plan (sebelum eksperimen dimulai) &darr; Controlled Execution (skenario satu per satu) &darr; Data Collection (setiap metrik, setiap run) &darr; Data Logging (terstruktur, timestamped) &darr; **Dataset for Analysis**

</div>

> Eksekusi **tanpa execution plan** = memasak tanpa resep. Mungkin jadi, tapi tidak terjamin konsistensinya.

---

## Execution Plan — Apa yang Harus Ada

**Sebelum menjalankan eksperimen pertama:**

```
EXECUTION PLAN — Eksperimen [N]

Skenario yang akan dijalankan:
  Skenario 1: [kondisi A] — [parameter spesifik]
  Skenario 2: [kondisi B] — [parameter spesifik]
  Skenario 3: [baseline]  — [parameter spesifik]

Jumlah run per skenario: 10
Random seeds untuk tiap run: [42, 123, 456, 789, 1024, ...]

Urutan eksekusi:
  1. Skenario baseline → 10 runs
  2. Skenario 1 → 10 runs
  3. Skenario 2 → 10 runs

Estimasi waktu per run: 45 menit
Total waktu: ~22.5 jam
```

---

## Mengapa Multiple Run Wajib?

**Satu run tidak cukup karena:**

1. Inisialisasi random (weight initialization, shuffle order) berbeda setiap run
2. Hardware variance (thermal throttling, background processes)
3. Satu run tidak bisa menghitung **standard deviation → tidak bisa uji statistik**

| Runs | Yang Bisa Dihitung | Yang Tidak Bisa |
|------|-------------------|----------------|
| 1 run | Point estimate saja | ± std, t-test, CI |
| 3 run | Mean (terlalu kecil untuk distribusi) | Reliable CI |
| 5 run | Mean ± std (minimum acceptable) | Large sample statistics |
| 10+ run | Mean ± std + t-test + CI | — |

> **Minimum dalam riset TI:** 5 run. Disarankan 10 run untuk stabilitas statistik.

---

## Struktur Data Logging

*Setiap run harus menghasilkan log yang lengkap*

```python
log_entry = {
    "run_id": "exp03_run07",
    "timestamp": "2026-04-13T10:25:33",
    "experiment_id": "exp-03",
    "scenario": "attention-mechanism",
    "random_seed": 789,
    "config": {
        "model": "BiLSTM",
        "attention": True,
        "learning_rate": 1e-3,
        "batch_size": 32,
        "epochs": 50
    },
    "results": {
        "f1_micro": 0.872,
        "f1_macro": 0.815,
        "precision": 0.889,
        "recall": 0.856,
        "training_time_sec": 2723
    },
    "hardware": "RTX 3090, 24GB VRAM, CUDA 11.8"
}
```

---

## Konsistensi Eksekusi — Checklist Setiap Run

*Sebelum memulai setiap run, pastikan:*

| Item | Cek |
|------|-----|
| Environment aktif (conda/venv) | `conda activate rti-exp` |
| Config file benar untuk skenario ini | `cat configs/exp_03_s1.yaml` |
| Random seed di-set | Set di numpy, torch, Python random |
| Dataset di lokasi yang benar + checksum OK | `md5sum dataset.csv` |
| GPU memory kosong | `nvidia-smi` |
| Log directory tersedia | `mkdir -p logs/exp03/` |
| Tidak ada proses berat yang berjalan | Tutup browser, aplikasi lain |

> Konsistensi eksekusi bukan paranoia — ini adalah standar ilmiah.

# Cognitive Traps
## Bab 10 — Experiment Execution

---

## Cognitive Traps — Bab 10

**"Satu run sudah cukup kalau hasilnya bagus"**
"Bagus" dalam satu run mungkin keberuntungan (lucky seed). Tanpa multiple run, tidak ada cara mengetahui apakah hasil tersebut stabil atau artifact dari kondisi spesifik satu eksekusi.

**"Data logging berlebihan, cukup catat hasil akhir saja"**
Ketika ada anomali atau hasil yang tidak terduga, log yang lengkap adalah satu-satunya cara untuk menginvestigasi. Logging minimal = debugging impossible. Disk space murah, waktu investigasi mahal.

**"Eksperimen bisa dijalankan sambil mengerjakan yang lain"**
Background processes mengkonsumsi CPU/GPU/RAM dan dapat mempengaruhi throughput dan latency measurement. Untuk eksperimen yang mengukur performa sistem, isolasi resource wajib.

---

## Studi Kasus 1 — Single Run Disaster (Basic)

**Konteks:** Mahasiswa melaporkan F1=91.5%. Dosen meminta run ulang. Hasil: 84.2%.

**Investigasi:**
- Run pertama: lucky seed, distribusi batch training kebetulan balans
- Run ulang: seed berbeda, batch distribution berbeda
- Variance sangat tinggi: std = 3.7% → model tidak stabil

**Tabel dari 5 run:**
| Run | Seed | F1-score |
|-----|------|---------|
| 1 | 42 | 91.5% ← yang dilaporkan |
| 2 | 123 | 84.2% |
| 3 | 456 | 87.1% |
| 4 | 789 | 85.8% |
| 5 | 1024 | 86.3% |
| **Mean ± Std** | | **87.0 ± 2.6%** |

**Pelajaran:** F1 yang sebenarnya adalah 87.0 ± 2.6%, bukan 91.5%.

---

## Studi Kasus 2 — Eksekusi Tidak Konsisten (Advanced)

**Konteks:** Researcher membandingkan dua model. Model A selalu dijalankan di pagi hari (server dingin), Model B di sore hari (server panas, thermal throttling aktif).

**Hasil:** Model A 15% lebih cepat dalam inference time.

**Masalah:** Perbedaan inference time bukan karena model — tapi karena kondisi hardware yang berbeda.

**Protokol eksekusi yang benar:**
1. Randomize urutan eksekusi per run (Model A/B dijalankan bergantian dalam satu sesi)
2. Jalankan warm-up run sebelum pengukuran (GPU dalam kondisi stabil)
3. Ukur hardware state sebelum setiap run (`nvidia-smi`, CPU temperature)
4. Catat semua di log

---

## Format Dataset Mentah

*Hasil semua run harus tersimpan dalam format yang terstruktur*

```
results/
  exp03_summary.csv          ← semua run, semua skenario
  exp03_raw/
    run_01_seed42.json
    run_02_seed123.json
    ...
  exp03_config/
    scenario_1_attention.yaml
    scenario_2_baseline.yaml
```

**Format `exp03_summary.csv`:**
```csv
run_id,scenario,seed,f1_micro,f1_macro,precision,recall,time_sec
exp03_s1_r1,attention,42,0.872,0.815,0.889,0.856,2723
exp03_s1_r2,attention,123,0.865,0.810,0.882,0.849,2698
exp03_s2_r1,baseline,42,0.821,0.768,0.844,0.799,2511
```

---

## Research vs Engineering — Execution

| Aspek | Engineering | Research |
|-------|------------|---------|
| Eksekusi | Run sekali, jika berhasil → selesai | Minimal 5 run per skenario |
| Kondisi eksekusi | Tidak disebutkan | Dikontrol dan didokumentasikan |
| Data yang disimpan | Hasil akhir saja | Semua run, semua metrik, semua log |
| Anomali | Dibuang / diabaikan | Dicatat dan diinvestigasi |
| Urutan eksekusi | Tidak penting | Randomized untuk menghindari order bias |

---

## Ringkasan Pertemuan 10

| Konsep | Inti |
|--------|------|
| Execution Pipeline | Design → Plan → Execution → Collection → Logging → Dataset |
| Multiple Run | Min. 5 runs → bisa hitung mean ± std → bisa uji statistik |
| Data Logging | Setiap run: ID, timestamp, config, result, hardware |
| Konsistensi | Checklist yang sama sebelum setiap run |
| Format Dataset | CSV summary + JSON detail per run + YAML config |

---

## Final Statement & Output Praktis

<div class="final">
"Data yang baik bukan data yang banyak, tetapi data yang dikumpulkan dengan konsistensi metodologi yang ketat."
</div>

### Output Praktis M10

Hasilkan dan kumpulkan:

1. **Log eksperimen** (minimal 5 run per skenario, format terstruktur)
2. **Dataset mentah** (`results/exp_summary.csv` + file per run)
3. **Catatan anomali** — apa yang terjadi di luar rencana selama eksekusi

*Dokumen ini menjadi dasar untuk validasi data di Bab 11.*
