chemistry in the curriculum. Your description should be completed with

competency standard, basic competencies, topics and subtopics!

Answer:

In this task, I used curriculum used at SMPN 1 Singaraja. At SMPN 1 Singaraja,

there are two different curriculum used, namely KTSP (School curriculum) and 2013

curriculum. The KTSP is used in VIII and IX grade, while the 2013 curriculum is used in VII

grade. The following are the descriptions of chemistry content in the curriculum used at

SMPN 1 Singaraja.

I. Students of JHS grade VII will learn chemistry as the following main competencies

and basic competencies, based on the 2013 curriculum.

The 2013 curriculum consists of main competencies and basic competencies. Later

on, it produces topic and sub topic. The main competencies of 2013 curriculum are

shown below.

a) Respecting and living based on religion believed;

b) Respecting and effectively doing behavior, such as honest, discipline,

responsible, care, tolerance, polite, confidence in interaction with social and

natural environment around the students;

c) Comprehending knowledge (factual, conceptual and procedural) based on

students curiosity about science, technology, art, and culture;

d) Trying, processing and presenting concretely (using, analyzing, assembling,

modifying and creating) and abstractly (writing, reading, calculating and

drawing) based on what students learnt in school as well as learning resources

II. Students of JHS grade VIII in first semester, especially in SMPN 1 Singaraja will

learn chemistry as the following standard competence and basic competencies (still

using the old curriculum):

Standard competence Basic competence

matter

a. Explaining the concept of atoms,

ions and molecules.

b. Relating the concept of atoms,

ions and molecules with the

chemical product in daily life.

c. Differentiating the molecules of

elements and molecules of

compounds.

The standard competence and the basic competence above produce some topic andsub topic:

a. Topic : Particle of matter

Sub topic : Atoms, Ions and Molecules

Students of JHS grade VIII in first semester will also learn chemistry as the following

standard competence and basic competencies:

Standard competence Basic competences

Understanding the uses of chemicals in

daily life

a. Searching information about uses

and side effects of chemicals in

daily life.

b. Communicating information about

uses and side effects of chemicals.

7/12

addictive substance and

psychotropic.

e. Avoiding the influence of addictive

substances and psychotropic. .

The standard competence and the basic competence above produce some topic and

sub topic:

a. Topic : Chemicals in daily life

Sub topic : cleaner

Bleach

Deodorizer

Disinfectant

Drugs

Addictive substances in food

2. Write short description of the content of each topic and subtopic!

Answer:

a. Topic : Characteristic of substance

Subtopic :

Physical change is a change in which no new substance is formed.

Example : ice change become water

Chemical change is a change of substance from one form of matter into

another form of matter. The reactants are placed on the left of the

arrow while the product is located to the right of the arrows.

The separation of mixtures can use several methods such as

crystallization, filtration, distillation, chromatography, etc. They are

physical properties of substance that are going to be separated, for

example particle size, boiling point, solubility, adsorption, etc.

Acid and Base indicators

There are the different characteristic of acid and base

Acid Base

sour Bitter

Turn the red

litmus to blue.

Turn the blue

litmus to red.


8/12

Indicators is needed to determine whether a solution is acid, base. Litmus paper is a

common acid-base indicator. If acids the blue litmus will change become red while

bases the red litmus will change become blue litmus.

b. Topic: The impact of pollution for living things

Subtopic:

Pollution

The act or process of polluting or the state of being polluted, especially the

contamination of soil, water, or the atmosphere by the discharge of harmful

substances

The effect of pollution for living things

The effects of pollution are environment degradation and human health

The solution to avoid Pollution

c. Topic: Global warming and ecosystem

Sub topic:

Greenhouse effect

The reason of occurrence of global warming

The effect to the ecosystem

The solution to decrease the effect of Global warming

d. Topic : Particle of matter

Subtopic :

Atom is smallest particle of element. It cannot be decomposed become simpler matter

using an ordinary chemical reaction. Example: Ion is an atom or combination of

several atoms that has electrical charge either positive or negative. If atom accept the

electron, it will change become negative ion (anion) and also if atom release the

electrons it will change become positive ion (cation). Molecule is small particles from

substance which has their properties. Molecules composed of two or more same or

different atoms.

Example: Molecules: CO2, H2O

Atom : Nitrogen atom, Sulfur atom, Chloride atom.

Ion : Sodium ion (Na+), Calcium (Ca2+).

e. Topic : Chemicals in daily life


9/12

Subtopic :

The chemical in daily life is the topic is very close with the students. Students will see

many chemical in environment such as cleaner, fragrance, and pesticides. Also the

addictive substance and psychotropic. It chemical also have negative effect to

environment. There are uses and negative effect to environment:

Cleaner, fragrance and peptides is chemical in daily life we use that. But, the negative

effect of it chemical for environment because it will be pollution of water and soil.

Because, the pollutant in water and soil cant decompose by bacteria.

Chemicals in food can be distinguished into two kinds those are natural and artificial

chemicals:

The natural chemical are chemical from plants or animals such as peppers, sugar, salt

and the others

The artificial chemical are chemicals produced by industry through a chemical

reaction from the certain chemical compounds such as monosodium glutamate,

saccharine, monosodium glutamate.

The addictive substance an psychotropic also the chemicals daily life. This substance

has many negatives effect for human life. But if use correctly it can useful for humans

such as anesthetic.

Narcotic comes from three kind of plants that is Papaver somniferum(opium),

Erythroxylum coca (cocaine) and cannabis sativa (hashish). Generally, narcotics

can be distinguished into four kinds those are depressant, stimulant,

hallucinogen and dependent narcotics.

Psychotropic is a kind of narcotics which are synthetic substance which have

properties of stimulant (amphetamine and methamphetamine) and depressant

(barbiturate and benzodiazepine).

3. Find out and write learning resources that can be used to support the teaching

learning process of JHS Chemistry.

Answer:

Udin Saripuddin and Winataputra in Syaiful Bahri a nd Aswan Zain (2006:122) classified

learning resources into five categories such as human, books, mass media, environment, and

educational media.

a. Human

Chemistry for Students in Junior High School: SMPN 1 Singaraja

Chemistry for junior high school is series of chemistry material which is included in

one lesson, natural science. In SMPN 1 Singaraja, curriculum which is used recently in is

2013 curriculum for the 7th grade, and KTSP or school curriculum for the 8th grade.

The 2013 curriculum which is used in 7 th grade consist of 4 main competencies, 4

general basic competencies and several basic competencies related to the content of

chemistry. The several basic competencies related to the content of chemistry cover some

several chemistry topics, namely characteristics of substance, the impact of pollutant for

living things and the global warming and ecosystem. For the 8th grade, there are two

standard competence. The first standard competence which ask students to be able to explain

explaining the concept of particle of matter is learned in first semester of grade VIII. This

standard competence produce one topic namely atom, ion and molecule. The second standard

competence which ask students to understand the uses of chemicals in daily life is also

learned in first semester of grade VIII. This standard competence produce the topic of

chemicals in daily life. Meanwhile, it is used some learning resources in the process of

teaching and learning of junior high school chemistry. Human, books, educational media,

mass media and environment are able to provide supports as the resources of the process of

teaching and learning of junior high school chemistry.

Based on the explanation above, it can be concluded that students in SMPN 1

Singaraja learn chemistry in 7th and 8th grade. The 7th grade learn chemistry based on 2013

curriculum, while the 8th grade learn chemistry based on KTSP curriculum.
