Abstrak: LDITP-IPB merupakan laboratorium pengujian yang mengacu pada SNI 17025 harus mengutamakan kepuasan konsumen. Penelitian ini bertujuan untuk: mengidentifikasi karakteristik konsumen, mengidentifikasi proses keputusan pembelian dan menganalisis tingkat kepuasan konsumen LDITP-IPB. Dalam penelitian ini digunakan analisis deskriptif, Customer Satisfaction Index dan Importance Perpormance Analysis. Hasil penelitian menunjukkan bahwa kualitas pelayanan LDITP-IPB memiliki indeks kepuasan konsumen sebesar 84.55 persen dengan kriteria sangat puas. Dari hasil metode IPA, atribut-atribut pelayanan yang perlu diperbaiki untuk meningkatkan kepuasan konsumen LDITP-IPB yaitu: pengujian harus dilakukan dengan tepat waktu sesuai perjanjian, kemampuan laboratorium memberikan penjelasan atas hasil pengujian, daya tanggap dalam menangani permintaan pengujian, kesopanan dan keramahan staff laboratorium, dan biaya pengujian yang sesuai dan bersaing.

Abstrak: LDITP-IPB is a testing laboratory ISO 17025 refers to give priority to customer satisfaction. The purposes of this research are: identified characteristics of consumers, identify the process of buying decision and to analysis the level of customer satisfaction of LDITP-IPB. This study used a descriptive analysis, Importance Performance Analysis and Customer Satisfaction Index. The results showed that the service quality of LDITP-IPB obtained customer satisfaction index by 84.55 percent, which means very satisfied in the criteria. From the results of the IPA method, the service quality attributes that need to be improved LDITP-IPB are: testing should be done on time based on the agreement, the ability to provide an explanation of laboratory testing results, responsiveness in handling testing requests, courtesy and friendliness employees, than appropriate and competitive cost of testing.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
