# Bab 8 — Proposal & Checkpoint
## Integrasi Fase Thinking + Designing

*Pertemuan 8 (M8) &nbsp;|&nbsp; Bab Integratif &nbsp;|&nbsp; UTS Checkpoint*

Fase: **Integratif** (M8) — merangkum Bab 1–7 ke dalam Proposal Riset

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

---

## Tujuan Pertemuan 8

Bab ini **berbeda** dari pertemuan biasa. Tidak ada konsep baru.

Tujuan: mengintegrasikan seluruh output M1–M7 menjadi **satu dokumen proposal riset yang koheren**.

> Proposal bukan kumpulan tugas dari 7 pertemuan yang ditempelkan bersama.
> Proposal adalah **argumen ilmiah yang utuh** — tiap bagian menjawab satu pertanyaan,
> dan bersama-sama membuktikan bahwa riset Anda layak dan feasible.

**Di akhir pertemuan ini, Anda memiliki:**
- Dokumen proposal riset lengkap (8 bagian)
- Kemampuan mengidentifikasi inkonsistensi antar bagian
- Kesiapan untuk mempresentasikan dan mempertahankan proposal

---

## Integration Map — Bab 1 sampai 7

*Semua output dari 7 pertemuan harus saling terhubung*

<div class="highlight-box">

**[Bab 1]** Research Mindset → Etika & Validitas

**[Bab 2]** Problem Statement + **[Bab 3]** Literature & Gap → **[Bab 4]** RQ + H0/H1 + Contribution

&darr; **[Bab 5]** Variabel + Metrik + Tipe Data

&darr; **[Bab 6]** Arsitektur Sistem (traceability ke variabel)

&darr; **[Bab 7]** Desain Eksperimen (skenario + controlled + validity)

&darr; **PROPOSAL RISET** (dokumen terintegrasi)

</div>

---

## Anatomi Proposal Riset — 8 Bagian

| No | Bagian | Sumber dari Bab | Pertanyaan yang Dijawab |
|----|--------|----------------|------------------------|
| 1 | **Latar Belakang** | Bab 2 + Bab 3 | Mengapa masalah ini penting dan belum terjawab? |
| 2 | **Rumusan Masalah** | Bab 2 | Apa tepatnya yang akan diteliti? |
| 3 | **Tinjauan Pustaka** | Bab 3 | Apa yang sudah diketahui dan apa gap-nya? |
| 4 | **Research Question** | Bab 4 | Pertanyaan apa yang akan dijawab? |
| 5 | **Kontribusi** | Bab 4 | Apa yang baru dari riset ini? |
| 6 | **Metodologi** | Bab 5 + 6 + 7 | Bagaimana hipotesis akan diuji? |
| 7 | **Jadwal & Sumber Daya** | Bab 7 | Apakah feasible dalam satu semester? |
| 8 | **Referensi** | Semua bab | APA 7th, min. 15 referensi |

---

## Koherensi Vertikal — Konsistensi antar Bagian

*Setiap bagian harus konsisten dengan semua bagian yang lain*

**Cek 1: Problem ↔ RQ**
> Problem: "Tidak ada studi tentang efektivitas SMOTE di dataset fraud perbankan syariah Indonesia"
> RQ: "Apakah SMOTE meningkatkan Recall dalam deteksi fraud di dataset perbankan syariah Indonesia?"
> Konsisten — RQ menjawab secara langsung gap yang disebutkan di Problem

**Cek 2: RQ ↔ Metodologi**
> RQ: "...meningkatkan Recall..."
> Metodologi: mengukur Accuracy dan Precision saja
> Inkonsisten — Recall harus menjadi metrik utama

**Cek 3: Hipotesis ↔ Statistical Test**
> H1: "perbedaan signifikan (p < 0.05)"
> Statistical plan: visualisasi grafik saja
> Inkonsisten — butuh t-test atau Wilcoxon

---

## Koherensi Horizontal — Argumen yang Mengalir

Proposal harus bisa dibaca sebagai satu narasi, bukan kumpulan potongan:

**Alur argumentasi yang baik:**

<div class="highlight-box">

"Di bidang X, masalah Y terjadi karena Z. *[Latar Belakang]* Studi-studi sebelumnya telah mencoba A, B, C, namun belum ada yang... *[Tinjauan Pustaka]* Oleh karena itu, riset ini bertanya: *[RQ]* Kontribusi yang diharapkan adalah *[Contribution]*. Untuk membuktikan hipotesis H1, kami merancang eksperimen dengan *[metodologi]* yang mengukur *[metrik]* terhadap baseline *[X]*."

</div>

> Jika pembaca bisa mengikuti argumen ini tanpa tersesat → proposal koheren.

# Cognitive Traps
## Proposal & Integrasi

---

## Cognitive Traps — Bab 8

**"Proposal = kumpulan tugas dari bab sebelumnya yang di-paste"**
Proposal adalah dokumen baru yang menulis ulang semua elemen dalam alur argumentasi yang koheren. Copy-paste tugas per bab tanpa koneksi menghasilkan proposal yang patchwork — tidak lulus.

**"Copy-paste methodology dari paper lain"**
Metodologi harus spesifik untuk RQ Anda, bukan template umum. Reviewer tahu ketika metodologi generik tidak sesuai dengan RQ yang diklaim.

**"Jadwal: semua selesai di bulan terakhir"**
Jadwal yang tidak realistis adalah red flag. Setiap tahap (implementasi, pengambilan data, analisis, penulisan) butuh buffer waktu. Gagal dalam satu tahap akan mempengaruhi semua yang berikutnya.

**"Tidak ada kemungkinan gagal"**
Proposal yang tidak mengidentifikasi risiko kegagalan tidak realistis. Selalu sertakan: "Jika kondisi X tidak tercapai, rencana alternatifnya adalah Y."

---

## Template Integrasi — Self-Check Proposal

<div class="checkpoint">

**Gunakan checklist ini sebelum mengumpulkan proposal:**

- [ ] Problem Statement sudah divalidasi dengan 5 kriteria kualitas (Bab 2)
- [ ] Literature review berisi ≥ 15 referensi dengan gap yang teridentifikasi (Bab 3)
- [ ] RQ spesifik, measurable, dan testable (Bab 4)
- [ ] Contribution claim eksplisit (improvement/comparison/novel) (Bab 4)
- [ ] H0/H1 yang falsifiable disertai statistical test yang direncanakan (Bab 4)
- [ ] Variabel + metrik + justifikasi terdokumentasi (Bab 5)
- [ ] Arsitektur sistem dengan traceability ke variabel (Bab 6)
- [ ] Dokumen desain eksperimen lengkap (skenario, controlled, validity threats) (Bab 7)
- [ ] Koherensi: Problem ↔ RQ ↔ Metodologi ↔ Metrik
- [ ] Jadwal realistis dengan buffer untuk setiap fase

</div>

---

## Rubrik Evaluasi Proposal

| Kriteria | Bobot | Level 1 (Lemah) | Level 2 (Cukup) | Level 3 (Kuat) |
|----------|-------|----------------|----------------|----------------|
| **Kejelasan masalah & gap** | 25% | Topik, bukan masalah | Masalah ada, gap kurang jelas | Problem + gap + validation |
| **Ketajaman RQ & Hipotesis** | 25% | RQ terlalu umum | RQ spesifik, hipotesis ada | RQ SMART, H0/H1 falsifiable |
| **Kelengkapan metodologi** | 30% | Deskripsi alat saja | Ada metrik, desain eksperimen parsial | Controlled, variabel terisolasi, validity |
| **Koherensi argumen** | 20% | Tiap bagian berdiri sendiri | Ada kesatuan tapi ada inkonsistensi | Alir argumen mulus Problem→Conclusion |

---

## Struktur Presentasi Proposal (10 menit)

**Slide 1:** Judul + nama + institusi (30 detik)

**Slide 2:** Latar Belakang + Masalah (2 menit)
- Fenomena nyata + data pendukung
- Apa yang sudah ada dan apa gap-nya

**Slide 3:** RQ + Contribution (1.5 menit)
- Satu kalimat RQ yang tajam
- Satu kalimat contribution yang eksplisit

**Slide 4:** Metodologi ringkas (3 menit)
- Workflow eksperimen
- Variabel (indep, dep, control)
- Metrik + statistical test

**Slide 5:** Jadwal + Ekspektasi Hasil (1 menit)

**Q&A:** 5–10 menit

---

## Pertanyaan yang Sering Diajukan Penguji

**Tentang Problem:**
*"Mengapa masalah ini penting? Siapa yang dirugikan jika tidak diselesaikan?"*

**Tentang RQ:**
*"Apakah RQ ini sudah ada jawabannya di paper yang Anda sitasi?"*

**Tentang Metodologi:**
*"Mengapa memilih metrik X, bukan Y?"*
*"Bagaimana Anda memastikan baseline-nya fair?"*

**Tentang Feasibility:**
*"Apakah dataset ini tersedia secara publik? Berapa ukurannya?"*
*"Bagaimana jika H0 tidak ditolak?"*

> Persiapkan jawaban berbasis **data dan referensi** untuk setiap pertanyaan ini.

---
