Statistical Classification (KBKI & KBLI)

This method is used to retrieve the list of Indonesian Standard Industrial Classification (KBLI) & Indonesian Standard Commodity Classification (KBKI) from the BPS API. It enables users to access information regarding classification codes and their descriptions.

Enums

There are two enum classes that can be used as parameters.

ClassificationType

ClassificationType is the base class for determining the type of classification. This class is then extended by KBLIType and KBKIType. Each of these classes has the following options.

• KBLIType

  Enum	Value	Description
  KBLI.y2009	kbli2009	KBLI year 2009
  KBLI.y2015	kbli2015	KBLI year 2015
  KBLI.y2017	kbli2017	KBLI year 2017
  KBLI.y2020	kbli2020	KBLI year 2020

  To make a request to the detail endpoint, the KBLI code needs to be formatted in the kbli_year_code format. This class also facilitates this formatting process through the urlParamGenerator method which accepts the code parameter.

  Example:

  final url = KBLIType.y2009.urlParamGenerator('24');
  /// result: kbli_2009_24
  final value = KBLIType.y2009.value;
  /// result: kbli2009
  final year = KBLIType.y2009.year;
  /// result: 2009

• KBKIType

  Enum	Value	Description
  KBKI.y2015	kbki2015	KBKI year 2015

  To make a request to the detail endpoint, the KBKI code needs to be formatted in the kbki_year_code format. This class also facilitates this formatting process through the urlParamGenerator method which accepts the code parameter.

  Example:

  final url = KBKIType.y2015.urlParamGenerator('24');
  /// result: kbki_2015_24
  final value = KBKIType.y2015.value;
  /// result: kbki2015
  final year = KBKIType.y2015.year;
  /// result: 2015

ClassificationLevel

ClassificationLevel is the base class for determining the group/level of classification. This class is then extended by KBLILevel and KBKILevel. Each of these classes has the following options.

• KBLILevel

  Enum	Value	Description
  KBLILevel.category	category	Represents the main classification. Marked with a single alphabet.
  KBLILevel.primaryGroup	primary group	Detailed description from category, each coded with two digits.
  KBLILevel.group	group	Further details from the primary group, each coded with three digits. The first two indicate the primary group and the last digit the economic activity.
  KBLILevel.subGroup	subgroup	Further detail from a group's economic activities, coded with four digits. The first three indicate the group and the last digit specifies the sub-group.
  KBLILevel.cluster	cluster	Distinguishes activities within a subgroup into more homogeneous activities, coded with five digits.

  This class also facilitates the KBLI code validation process through the validateCode method.

  Example:

  final isValid = KBLILevel.category.validateCode('A');
  /// result: true
  final value = KBLILevel.category.value;
  /// result: category

• KBKILevel

  Enum	Value	Description
  KBKILevel.section	section	General classification outline, 1-digit code, 5 sections, 0-4.
  KBKILevel.division	division	Detailed description from section, 2-digit code.
  KBKILevel.group	group	Further details from division, 3-digit code.
  KBKILevel.classes	classes	Further details from group, 4-digit code.
  KBKILevel.subClass	subclass	Detailed from classes, 5-digit code.
  KBKILevel.commodityGroup	commodity group	Detailed from sub-classes, 7-digit code for commodity group.
  KBKILevel.commodity	commodity	Detailed from commodity group, 10-digit code for commodities.

  This class also facilitates the KBLI code validation process through the validateCode method.

  Example:

  final isValid = KBKILevel.section.validateCode('A');
  /// result: false
  final value = KBKILevel.section.value;
  /// result: section

Parameters

Parameter	Type	Description
id	String	ID of specific KBLI/KBKI. It must be in type_year_code format. You can utilize urlParamGenerator method from enum class.
type	ClassificationType	Specifies the classification type from the KBLIType or KBKIType enum.
lang	DataLanguage	The language used for KBLI/KBKI data (default: DataLanguage.id).
page	int	Page number (default: 1).
perPage	int	Number of data per page (default: 10).

Example

Here is an example of usage:

// Fetch KBLI/KBKI data from the BPS API
const type = KBLIType.y2015;

final result = await StadataFlutter.instance.view.statisticClassifications(
  id: type.urlParamGenerator('A'),
  type: type,
);
final statisticClassificationsList = result.data;
final pagination = result.pagination;

// Display page information
print('Current Page: ${pagination.page}');
print('Total Pages: ${pagination.pages}');
print('Data Count on This Page: ${pagination.count}');
print('Per Page: ${pagination.perPage}');
print('Total: ${pagination.total}');
print('------------------------');

// Display the retrieved statuc classification data
for (final statisticClassifications in statisticClassificationsList) {
    print('Statistic Classification ID: ${statisticClassifications.id}');
    print('Source: ${statisticClassifications.source}');
    print('Title: ${statisticClassifications.title}');
    print('Description: ${statisticClassifications.description}');
    print('Last Update: ${statisticClassifications.lastUpdate}');
