1 · Dasar

An amount held within a system.
Separate physical evidence from value judgements. A stock is an amount at a time; a flow is an amount per time. Sustainability decisions require ecological, social and economic evidence and a stated scale.
Draw the system boundary before calculating a budget. Identify inflows, outflows and possible unmeasured terms. Compare stakeholder claims using the same evidence, then explain where values lead to different choices.

stok: Jumlah yang disimpan dalam sebuah sistem
aliran: Transfer jumlah per satuan waktu

2 · Ekologi

A defined area used for sampling.
Estimate total abundance by multiplying mean density by area, with consistent units. This assumes sampled areas represent the habitat. Patchiness and too few samples widen uncertainty.
Choose coordinates with random numbers before visiting the patches. Record quadrat area and counting rules. For a transect, use fixed distances and measure a relevant abiotic variable. Do not damage habitats or sample unsafe locations.

kuadrat: Area terdefinisi yang digunakan untuk pengambilan sampel
populasi: Organisme satu spesies dalam area terdefinisi
stok: Jumlah yang disimpan dalam sebuah sistem
aliran: Transfer jumlah per satuan waktu

3 · Keanekaragaman hayati dan konservasi

The number of species recorded.
Compare surveys with similar area, effort, season and identification rules. A diversity index is meaningful only with its formula and conventions specified. Habitat fragmentation can affect movement and gene flow even when total area changes little.
Use non-destructive field sampling approved by the school. Identify organisms with a suitable key and record uncertain identifications rather than inventing species. Combine ecological evidence with stakeholder perspectives on land use.

kekayaan spesies: Jumlah spesies yang tercatat
keseragaman: Seberapa merata individu terdistribusi di antara spesies

4 · Air

Nutrient enrichment with ecological consequences.
Distinguish concentration from total pollutant load. Dilution can reduce concentration without removing the pollutant mass. A management plan should consider upstream causes, users and effects on other parts of the catchment.
Collect approved water-quality observations at matched sites and times. Use calibrated instruments and consistent sampling depth. Avoid contact with contaminated water and do not infer potability from clarity.

eutrofikasi: Pengayaan nutrisi dengan konsekuensi ekologis
beban polutan: Massa polutan yang ditransfer per waktu

5 · Tanah

Removal and transport of soil or rock.
Distinguish total yield from yield per area and energy input. Sustainable management must consider regeneration rates and impacts beyond the farm boundary. Different stakeholders may rank food security, biodiversity and income differently.
Compare management options using a stated functional unit and the same timescale. Use approved secondary datasets or non-destructive soil observations. Explain trade-offs instead of claiming a method has no disadvantages.

erosi: Pengangkatan dan transportasi tanah atau batuan
sumber: Bahan atau layanan yang digunakan untuk memenuhi kebutuhan

6 · Atmosfer dan perubahan iklim

Actions addressing causes of environmental change.
Distinguish mitigation, which addresses drivers, from adaptation, which reduces harm from impacts. A policy assessment needs evidence about effectiveness, cost, equity and uncertainty; one criterion is not the entire decision.
Compare multi-year data using consistent baselines. State the region, timescale and uncertainty. At HL, connect a management decision to law, economics and ethics rather than treating these lenses as extra definitions only.

mitigasi: Tindakan yang menargetkan penyebab perubahan lingkungan
adaptasi: Tindakan yang mengurangi dampak buruk dari pengaruh lingkungan

7 · Sumber daya alam

Removal and transport of soil or rock.
Distinguish total yield from yield per area and energy input. Sustainable management must consider regeneration rates and impacts beyond the farm boundary. Different stakeholders may rank food security, biodiversity and income differently.
Compare management options using a stated functional unit and the same timescale. Use approved secondary datasets or non-destructive soil observations. Explain trade-offs instead of claiming a method has no disadvantages.

erosi: Pengangkatan dan transportasi tanah atau batuan
sumber: Bahan atau layanan yang digunakan untuk memenuhi kebutuhan

8 · Populasi manusia dan sistem perkotaan

Movement into a population.
Compare rates with a common denominator and interval. An average can hide unequal access to services. At HL, evaluate how economic incentives, legal responsibilities and ethical priorities change an urban management proposal.
Use published demographic and city-service data with dates and definitions. Protect privacy when collecting local opinions. Compare the same geographical boundary rather than mixing an urban core with a whole metropolitan region.

imigrasi: Pergerakan masuk ke dalam populasi
indikator: Ukuran dari kondisi tertentu

HL.a · Hukum lingkungan

Implementation of rules through monitoring and consequences.
Distinguish the legal instrument from the evidence about its effect. A concentration limit can be satisfied while total pollutant load rises if flow increases. Evaluate monitoring coverage, detection probability, incentives, access to justice and effects on different groups. An observed change after a policy is compatible with an effect but also with rainfall, industrial changes or other interventions.
Use an attributed historical or clearly fictional permit and paired monitoring data. Identify the regulated activity, responsible authority, geographical boundary and date. Compare upstream/downstream and before/after observations where available, document sampling gaps, and discuss whose evidence or costs are excluded. Do not present this classroom model as advice about current local law.

penegakan: Penerapan aturan melalui pemantauan dan konsekuensi
yurisdiksi: Cakupan geografis atau institusional dari sebuah otoritas

HL.b · Ekonomi lingkungan dan ekologis

A transaction effect on a third party not fully reflected in its price.
In a simplified model, marginal social cost equals marginal private cost plus marginal external cost. A pollution charge can alter incentives, but selecting a charge requires evidence and a stated objective. Monetary totals do not by themselves settle distribution, irreversibility, uncertainty or whether a service can be substituted.
Construct a transparent table with a common currency, time period and system boundary. Separate measured expenditure from estimated environmental damage. Compare at least two valuation assumptions, identify who pays and who benefits, and consider a non-monetary indicator such as habitat condition. Label these as classroom scenarios rather than forecasts.

eksternalitas: Efek transaksi pada pihak ketiga yang tidak sepenuhnya tercermin dalam harganya
biaya sosial: Biaya privat ditambah biaya eksternal dalam model yang disebutkan

HL.c · Etika lingkungan

Value considered independent of usefulness to another party.
Separate descriptive claims from normative claims. A species count is evidence about the sampled community; deciding that every species has intrinsic value is a value position. Compare consequences, rights, duties and fairness across generations. A defensible argument states its values, uses accurate evidence and acknowledges competing claims rather than disguising a value choice as a calculation.
Use a fictional planning dispute or an attributed historical case. Build an argument table: stakeholder, factual claim, evidence, value principle and possible response. Include affected communities and future generations without pretending to speak for them. Use voluntary anonymous classroom positions; assess the reasoning rather than agreement with a preferred worldview.

nilai intrinsik: Nilai yang dianggap independen dari kegunaan bagi pihak lain
keadilan lingkungan: Perlakuan adil dalam beban lingkungan, manfaat, dan pengambilan keputusan

Practical · Program eksperimen

A quantified limitation on a measured result.
For a product or quotient, adding fractional uncertainties is a common maximum-uncertainty approximation. For a difference, add absolute uncertainties. A nonzero intercept can reveal an offset or an incomplete model.
Show units on axes and choose a sensible scale. Plot uncertainty bars where justified, draw a best-fit line rather than joining every point, and estimate steepest and shallowest plausible gradients when the course method calls for them.

ketidakpastian: Keterbatasan terkuantifikasi pada hasil pengukuran
kesalahan sistematis: Bias pengukuran yang konsisten

Menyiapkan diri untuk kualifikasi ini

ESS integrates ecological evidence with human values, systems and sustainability; it is not a generic Biology course.
HL adds environmental law, environmental/ecological economics and ethics as lenses integrated with topic evidence, alongside deeper topic coverage.
Both levels have practical work 30 h, collaborative sciences project 10 h and individual investigation 10 h. Use school-approved fieldwork and ethical social-data collection.
Written assessment and investigation details are recorded from the 2026 brief; the old SL-only 2017 brief is not the current course.
2026 assessment: SL Paper 1 is 1 h/25%, Paper 2 is 2 h/50%, investigation 25%; HL Paper 1 is 2 h/30%, Paper 2 is 2.5 h/50%, investigation 20%. Paper 1 uses an unseen case study; Paper 2 has short/data questions and structured essays. The individual investigation is a real student-formulated inquiry, 10 h and a maximum 3,000-word report.
