Kretek

Kretek is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kretek rather than just read about it. In short: Kretek () is a type of Indonesian cigarette made with a blend of tobacco, cloves and other flavors. They are available filtered or unfiltered.

Key takeaways

  • Kretek belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Kretek to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Kretek from memory before moving on to harder problems.

Reference excerpt

Kretek () is a type of Indonesian cigarette made with a blend of tobacco, cloves and other flavors. They are available filtered or unfiltered. The word "kretek" is an onomatopoetic term for the crackling sound of burning cloves. Partly due to favorable taxation compared to filtered "white" cigarettes, kreteks are by far the most widely smoked form of cigarettes in Indonesia, where they are preferred by about 90% of smokers. In Indonesia, there are hundreds of kretek manufacturers, including small local makers and major brands. Most of the widely known international brands, including Sampoerna, Bentoel, Nojorono, Djarum, Gudang Garam, and Wismilak originate from Indonesia. Nat Sherman of the United States produced cigarettes branded as "A Touch of Clove" but they were not true kreteks, since there was clove flavoring infused into small crystals located inside the filter, rather than actual clove spice mixed with the tobacco. Kreteks often serve as a base for Indonesian herbal cigarettes manufactured by small local brands, by adding various herbs in addition to clove spice. Compared with traditional cigarettes, studies have shown that kreteks contain significantly higher levels of nicotine, carbon monoxide, and tar, as well as several more chemicals, thus making them much more harmful overall.

History

The origin of kretek cigarettes can be traced to 1880. The creator of kretek was Hajj Djamhari, a native of Kudus in Indonesia's Central Java region. Suffering from chest pains, Djamhari attempted to reduce the pain by rubbing clove oil on his chest. Djamhari sought a means of achieving a deeper relief and smoked his hand-rolled cigarettes after adding dried clove buds and rubber tree sap. According to the story, his asthma and chest pains healed immediately. Word of Djamhari's product spread rapidly among his neighbors, and the product soon became available in pharmacies as rokok cengkeh; clove cigarettes. First marketed as a medicinal product, kreteks became widely popular. In those years, the locals used to hand-roll kreteks to sell on order without any specific brand, packing, or limits on ingredients used in production. A resident of Kudus named Nitisemito had the idea of starting serial production and selling kreteks under a proprietary brand name. Unlike other manufacturers, Nitisemito, who first created the Bal Tiga brand in 1906, enjoyed great success by implementing unprecedented marketing techniques, such as using embossed packs or offering free-of-charge promotional materials. Commercial manufacture did not start in earnest until the 1930s. Furthermore, he also developed a means of production called the abon system which offered opportunities for other entrepreneurs with insufficient capital. In this system, a person called an "abon" assumes the job of delivering finished products to the company which pays the price of piecework done whereas the company is liable to supply the necessary production materials to the "abons". Most manufacturers have since opted to have their workers working under the roof of their own factories, to maintain quality standards. Nowadays, only a few kretek manufacturers make use of the abon system. Between 1960 and 1970, and the earlier days of the New Order regime, kreteks became a national symbol against "white cigarettes". In the mid-1980s, the number of machine-produced cigarettes exceeded that of hand-rolled ones. One of the largest income sources of Indonesia, the kretek industry comprises 500 large and small manufacturers employing a total of around 10 million people. Since 2009, kreteks are not legal for sale in the United States. A variation of the kretek is sold: "cigars" that are similar in size and shape to the original kreteks, also with a filter and the original tobacco/clove blend, but in a tobacco-based paper.

Structure and ingredients The quality and variety of tobacco play an important role in kretek production. One kretek brand can contain more than 30 types of tobacco. Minced dried clove buds weighing about 1/3 of the tobacco blend are added. Sometimes the last process that machine-made or hand-rolled kreteks go through is the spraying of sweetener at the butt end of the cigarette.

Health effects

Djarum Black cigarettes sold in European, Southern African and South American countries have 10–12 mg tar and 1 mg nicotine, as indicated on the pack. This level of tar and nicotine is comparable to the majority of other regular or "full-flavor" cigarettes available. Djarum Black cigarettes produced for consumption in Indonesia contain a significantly higher quantity of tar and nicotine, 25 mg and 1.6 mg respectively. In Canada, Djarum Black cigarettes are listed as containing 44.2–86 mg of tar and 1.73–3.24 mg of nicotine, a significantly higher amount than most other cigarettes. Studies have also shown that kreteks contain much higher levels of carbon monoxide and several more chemicals not found in other cigarettes. The venous plasma nicotine and carbon monoxide levels from 10 smokers were tested after smoking kreteks and were found to be similar to non-clove brands of cigarettes, such as Marlboro. Rats were given equal inhalation doses of conventional tobacco cigarettes and kreteks over a short period. Those that had inhaled kreteks did not appear to show worse health effects compared to those that had inhaled conventional cigarettes. The study was repeated with a 14-day exposure and kreteks again did not produce worse health effects than conventional cigarettes. The eugenol in clove smoke causes a numbing of the throat which can diminish the gag reflex in users, leading researchers to recommend caution for individuals with respiratory infections. There have also been a few cases of aspiration pneumonia in individuals with normal respiratory tracts possibly because of the diminished gag reflex. Daily kretek users are more likely to experience symptoms of malabsorption, anorexia, bone and muscle loss compared with regular tobacco users.

Worked examples

Example 1 — a first encounter with Kretek

Start with the simplest possible case. Write down what Kretek claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kretek before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kretek ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kretek

In research
Kretek appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Kretek in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Kretek is common in secondary-school and first-year university syllabi. It links to neighbouring topics Culture of Indonesia, Indonesian inventions, Smoking in the United States, so understanding it makes those chapters shorter.
In everyday life
Look for Kretek outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
