Globalisasi di bidang ekonomi dan perdagangan bebas mangakibatkan

tingginya tingkat persaingan diantara perusahaan. Peningkatan kualitas produk

dengan penerapan Sistem Manajemen Kualitas ISO Seri 9000 merupakan langkah

yang ditempuh oleh perusahaan untuk menghadapi persaingan tersebut. PDAM

Tirtanadi Instalasi Pengolahan Air Deli Tua telah menerapkan Sistem Manajemen

Kualitas ISO Seri 9000 pada akhir tahun 2000.

Penelitian ini bertujuan untuk mengetahui Perbandingan Kualitas Air Minum

Sebelum dan Sesudah Penerapan Sistem Manajemen Kualits ISO Seri 9000 di

PDAM Tirtanadi Instalasi Pengolahan Air Deli Tua. Perbandingan dilaksanakan

terhadap variabel kualitas air yaitu pH, TUrbidity, dan chlorine. Penelitian ini juga

bertujuan untuk mengetahui penerapan sistem psrencanaan dan pengendalian

kualitas air minum sesuai dengan Sistem Manajemen Kualitas ISO Seri 9000.

Jumlah sampel yang digunakan untuk analisis ini adalah seluruh data kualitas

air minum selama 12 bulan (dua belas) bulan, yang dimulai dari bulan Juni 2000

sampai dengan bulan Mei 2001, yaitu sebanyak 6120 data untuk masing-masing

variabel pH, TUrbidity, dan chlorine.

Sumber data yang digunakan dalam

penelitian ini berasal dari Form Isian Data Kualitas Air Minum yang telah ada.

Pengujian hipotesis dengan menggunakan uji beda atau uji-t

(T-Test Two

Independent Sample)

pada tingkat kepercayaan 95%.

Diperoleh hasil pengolahan data untuk pH bahwa terdapat perbedaan yang

signifikan antara rata-rata pH air minum sebelum dan sesudah penerapan Sistem

Manajemen Kualitas ISO Seri 9000 di PDAM Tirtanadi Instalasi Pengolahan Air

Deli Tua. Nilai ph sesudah penerapan lebih sesuai dengan sasaran kualitas air

minum dibanding nilai ph sebelum penerapan Sistem Manajemen Kualitas ISO

Seri 9000.

Diperoleh hasil pengolahan data untuk turbidity bahwa terdapat

perbedaan yang signifikan antara rata-rata turbidity air minum sebelum dan

sesudah penerapan Sistem Manajemen Kualitas ISO Seri 9000 di PDAM Tirtanadi

Instalasi Pengolahan Air Deli Tua. Nilai turbidity sesudah penerapan lebih sesuai

dengan sasaran kualitas air minum yang ditetapkan dibanding nilai turbidity air

minum sebeJum penerapan Sistem Manajemen Kualitas ISO Seri 9000. Diperoleh

hasil pengolahan data untuk chlorine bahwa terdapat perbedaan yang signifikan

antara rata-rata chlorine air minum sebelum dan sesudah penerapan Sistem

Manajemen Kualitas ISO Seri 9000 di PDAM Tirtanadi Instalasi Pengolahan Air

Deli Tua. Nilai chlorine sesudah penerapan lebih optimal dari sebelurn penerapan

Sistem Manajemen Kualitas ISO Seri 9000.

Berdasarkan pengujian ketiga hipotesis maka dapat simpulkan bahwa

terdapat perbedaan yang signifikan antara rata-rata kualitas air minum sebelum

dan sesudah penerapan Sistem Manajemen Kualitas ISO Seri 9000 di PDAM

Tirtanadi Instalasi Pengolahan Air Deli Tua.

Berdasarkan pengamatan dan

penelitian di lapangan bahwa PDAM Tirtanadi Instalasi Pengolahan Air Deli Tua

telah melaksanakan operasional perusahaan sesuai dengan Sistem Manajemen

Kualitas ISO Seri 9000.

ABSTRACT

PANGERAN HKS, 2004, A Comparison of Drinking Water Quality Before and

After The Implementation of Quality Management System ISO 9000 Series at

PDAM Tirtanadi Water Treatment Installation Deli Tua, supervised by Rahim

Matondang (Chief), Herman Mawengkang (member), and Rahim Siregar

(member).

Globalization in Economic and Free Trade effects the highly increased

competition among companies around the world. And in order to face the

competition, companies should implement The Quality Management System ISO

9000 Series to increase the quality of products. Thus, by the end of the year 2000

PDAM Tirtanadi Water Treatment Installation Deli Tua implemented the Quality

Management System ISO 9000 Series.

The purpose of this research is to compare the drinking water quality before

and after the implementation of The Quality Management System ISO 9000 Series

at PDAM Tirtanadi Water Treatment Installation Deli Tua. The comparison is

treated towards the variables of water quality which are pH, turbidity, and chlorine.

Furthermore, this research is also done to know the implementation of the planning

system and quality control based on Quality Management System ISO 9000

Series.

Samples used for this study are all data

of

the drinking water quality during

12 months, started from June 2000 until May 2001. And there are 6120 datas for

each variables, pH, turbidity, and chlorine. The source of datas that are used for

this research dirived from the form of existing drinking water quality data.

Hypothesis test uses different test of T - Test ( T -

two

Test Independent Sample)

on significance level of 95%.

The result of pH data processing shows that there is a significant difference

between the average of drinking water pH before and after the implementation of

The Quality Management System ISO 9000 Series at PDAM Tirtanadi Water

Treatment Installation Deli Tua. The pH value after the implementation of The

Quality Management System ISO 9000 Series is better than before. The result of

turbidity data processing also shows a significant difference between the average

of tUrbidity drinking water before and after The Quality Management System ISO

9000 Series. The value of turbidity after the implementation of Quality Management

System ISO 9000 Series is better than the value of turbidity before that

implementation. And lastly, the chlorine data processing also shows a significant

difference between the average of drinking water chlorine before and after the

implementation of The Quality Management System ISO 9000 Series at PDAM

Tirtanadi Water Treatment Installation Deli Tua. The value of chlorine used after

the implementation is more optimal than before the implementation of The Quality

Management System ISO 9000 Series.

Based on the study, the 3 hypothesis proved that there is a significant

difference between drinking water quality before and after the implementation of

The Quality Management System ISO 9000 Series at PDAM Tirtanadi Water

Treatment Installation Deli Tua. Thus, observation and research in the field also

proved that PDAM Tirtanadi Water Treatment Installation Deli Tua has ran the

company's operations correctly according to the Quality Management System ISO

9000 Series.
