Pengelolaan Sampah pada Bangunan Tinggi - Waste Management

Main ideas and lessons (Waste management in high-rise buildings)

1. Waste management systems are critical for building operations

   • The video focuses on how to plan waste handling in high-rise buildings, including:
     • Calculating waste generation volume
     • Planning the waste disposal route
     • Determining required spaces (e.g., trash room, temporary storage, and related areas)

2. Waste generation must be estimated using SNI standards (Indonesia)

   • Waste generation varies significantly by:
     • Building function
     • Number of occupants
   • The method references:
     • SNI 19-3983-1995 (waste generation specifications for small and medium cities in Indonesia)
   • Waste generation is expressed as volume per unit time (commonly liters per person per day) or related ratios from SNI.

3. Two worked examples show function-based differences

   • The same number of occupants can produce very different waste volumes depending on building type.

#### Apartment / residence example

  - Assumptions:
      - **500 apartment units**
      - **4 people per unit** → **~2000 occupants**
      - SNI waste generation assumed: **2.5 liters/person/day**
  - Calculation:
      - 2000 × 2.5 L/day = **5000 L/day** = **~5 m³/day**
  - Implication:
      - Garbage storage space must be sized accordingly (storage containers/space may be larger than the computed generation volume).

#### Office example

  - Assumptions:
      - Office area: **20,000 m²**
      - Standard space: **10 m²/person** → 20,000 / 10 = **~2000 employees**
      - SNI waste generation assumed: **0.75 liters/person/day**
  - Calculation:
      - 2000 × 0.75 L/day = **1500 L/day** = **~1.5 m³/day**
  - Implication:
      - Office waste storage needs are much smaller than residential for the same occupant count.

1. Waste disposal route in a building (schematic process)
   • Waste travels through a chain of spaces managed by occupants, staff, and building management.

### Step-by-step route described

  1. **Waste source (occupants)**
        - Residents/employees throw trash into bins in units (using bags/plastic bags).

  2. **Transfer to the typical waste room (intermediate collection)**
        - Trash is moved from apartments/offices to the building’s **typical trash room**.
        - Ideally provide **3 bins/containers** for separation:
            - **Green** = organic waste
            - **Yellow** = inorganic waste
            - **Red/Orange** = B3 waste (hazardous waste category)
        - Typical trash room size is based on bin volume.
            - Example mentioned (residential scale): **~0.25 m³ (250 L)**
            - Approximate dimensions: **~90 cm height × 40–50 cm width**

  3. **Building service area circulation**
        - Trash is transported by building staff/handling officers.
        - Uses the **service lift/service chute corridor** concept:
            - Typical trash room → service route → downward for centralized temporary storage.

  4. **Temporary storage area in the building (TPS / main holding location)**
        - TPS is the **main temporary garbage storage** area.
        - Sized using the previously calculated waste generation volume.
        - TPS includes separation into types (organic/inorganic/B3), with further handling by cleaning staff.

  5. **Loading for garbage truck**
        - TPS should be located **as close as possible** to the garbage truck loading area.
        - Removal frequency can be **once per day** or **once every two days**, depending on transporter availability and conditions.

  6. **Truck transport to final disposal site**
        - After loading, waste is transported to the final processing/disposal area (generally referenced as a “Tosca Lapota area/scale” in the subtitles).

1. Design details for a typical trash room (what it should include)
   • The video explains functional and hygiene requirements for the typical trash room.

### Key design elements mentioned

  - **Ventilation**
      - Door includes **grilles** to support air circulation
      - Can be achieved via:
          - **Cross ventilation**, and/or
          - **Exhaust fan** to reduce:
              - **Odor**
              - **Humidity**

  - **Hygiene / maintenance support**
      - Provide a **sink** for washing hands
      - Include a **floor drain**
      - Use washable materials and an easy-to-clean floor finish (example term given: “floren”)

  - **Waste segregation consistency**
      - Green/yellow/red bin separation supports future sorting and handling.

1. Communal trash collection area (TPS) requirements

   • TPS placement can be:
     • Ground floor, or
     • Basement
   • TPS ideally has three partitions/rooms:
     • Inorganic waste
     • Organic waste
     • B3 waste (described as the smallest partition, but still separated)

   • Each partition should include:

     • Doors
     • Cleanable materials
     • Air circulation (cross ventilation or exhaust systems)

   • For building types with large organic/wet waste volumes (e.g., hotels):

     • AC may be added for organic waste areas to:
       • slow decay,
       • reduce unpleasant odors,
       • manage issues caused by frequent transport delays (not necessarily every day).

2. Placement and sizing logic (final planning guidance)

   • The video concludes with practical planning priorities:
     • Estimate trash room capacity based on:
       • building function
       • number of residents/occupants
     • Ensure the trash room is not too large and not too small for real needs.
     • Place the typical trash room as close as possible to the service lift/service chute (“service lip”).
     • Place the TPS near:
       • the truck loading area (typically in service ground floor/basement areas)
     • Match TPS elevation to the truck loading height to ease staff movement and loading.
