Please note that in the provided Java code snippet, the SPARQL query is enclosed within a string variable named sparqlQuery. Make sure to replace the placeholders like :resep_makanan and :6-7_bulan with actual URIs or prefixes that you're using in your OWL ontology. Additionally, the double quotes within the SPARQL query are escaped with a backslash (\") to include them as part of the string.

    SELECT ?resep_makanan
WHERE {
	?resep_makanan rdf:type :resep_makanan.
	?resep_makanan :resep_untuk :6-7_bulan.
	?malnutrisi rdf:type :malnutrisi.
	?malnutrisi :memiliki_penawar ?resep_makanan.
	FILTER regex(str(?malnutrisi),"beriberi")
}
ORDER BY ?resep_makanan
