Lis-alis

Lis-alis 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 Lis-alis rather than just read about it. In short: Lis-alis is a type of traditional boat of Madura, Indonesia. Lis-alis usually present in canals that provide salt evaporation service in southern part of Madura and around Surabaya.

Key takeaways

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

Reference excerpt

Lis-alis is a type of traditional boat of Madura, Indonesia. Lis-alis usually present in canals that provide salt evaporation service in southern part of Madura and around Surabaya. Until the present, lis-alis remained overwhelmingly popular as a fishing craft in Bangkalan and Sukolilo, while a larger version, the kroman, has been used in this area for at least a century for inshore transport work.

Etymology

It is also known as alisalis or alis alis. The name come from Indonesian word alis which means "eyebrows". This may refer to an ornamental motif which does resemble a pair of eyebrows, often applied to the top of the bow. Eyebrows are an important aspect of feminine beauty in traditional Indonesian culture, and these boats strongly associated with the feminine — on the northwest coast they were commonly referred as parao bini, which means "female boat".

Description

These boats come from varying size between 5 metres long to more than 10 metres. Usually the length is no more than 4 times the size of its mast. The ribs are never excessive on the hull. The hull was held together by the boat's stempost in its tip, with hidden wooden dowel in the corner of the planks. In the 19th century there are some models with outrigger, but now they are rarely seen. The rigging used is the traditional triangular layar lete with short mast. At the stern of the boat is a wide storage space (about as wide as the boat itself), covered from rain by bamboo cover. A row of fire pots in this storage space supports the pots for boiling water. Firewood and fish were stored in the deckhouse. These perahu were lightly built so they may be fast, for carrying fish from mayangs in the Java sea. Small lis alis is an open vessel, it doesn't have roofing. Lis alis is a bifid-ended boat (with double stem and sternpost), the lower "jaw" called antek, cantek or jabaran is an elongation of the keel that functions as a bumper.

Role

Lis-alis boats usually provide cargo carrying services in general, carrying the catch from fishing boats at the same area, and as ferry boats from Gresik to Madura. Bigger lis-alis act as favorite transport boat to carry fishes from other fisherman in sea to Surabaya. The boats is about 10–12 metres long with a deckhouse that carried processing plant for preserving the fish in the sea. They brought about 0.5 ton rough sea salt in a box. Fishes were sterilized in cooking water, then grinded and stirred in the pot until it cools down and packed in bottles to be sold as shrimp paste. The reason for this sea sterilization is that there are not enough space to dry the fish in the boat, rainstorms often occurring and ice was not used. This means a cargo of fishes won't last long, especially if there are sudden strong winds.

Worked examples

Example 1 — a first encounter with Lis-alis

Start with the simplest possible case. Write down what Lis-alis 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 Lis-alis 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 Lis-alis 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 Lis-alis

In research
Lis-alis 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 Lis-alis 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
Lis-alis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Boats of Indonesia, Indonesian inventions, so understanding it makes those chapters shorter.
In everyday life
Look for Lis-alis 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.
