Judul: Satisfaction of Visitor to Mandalawangi Camping  Ground, Mount Gede Pangrango National Park (TNGGP)
Abstrak: Kepuasan pengunjung merupakan fungsi dari persepsi atas kinerja pengelola dengan harapan pengunjung. Penelitian ini bertujuan untuk mengidentifikasi proses pengambilan keputusan, kepuasan pengunjung, kesenjangan, serta rekomendasi strategi untuk pengelola. Pengumpulan data dilakukan dengan menyebarkan kuesioner kepada 255 pengunjung, observasi lapang, dan studi literatur. Metode analisis data yang digunakan dalam penelitian yaitu analisis deskriptif, chi-square, IPA, CSI, dan analisis gap. Hasil akhir dari proses pengambilan keputusan, pengunjung merasa puas terhadap fasilitas maupun pelayanan. Hasil analisis IPA, terdapat satu atribut yang harus diperbaiki yaitu ketersediaan tempat parkir. Hasil analisis CSI, tingkat kepuasan pengunjung sebesar 77.21% dan termasuk kategori puas. Hasil dari analisis gap, terdapat tiga atribut yang memenuhi kepuasan pengunjung dan sebelas atribut yang belum memenuhi kepuasan pengunjung. Rekomendasi hasil penelitian untuk pengelola terdapat dua hal utama yaitu perbaikan mengenai fasilitas umum dan sarana informasi., Visitor satisfaction is a function of perceptions of management performance and visitor expectations. The purpose of this research is to identify decision-making processes, visitor satisfaction, gaps, and strategy recommendations for managers. Data collection was carried out by distributing questionnaires to 255 visitors, field observations, and literature studies. The data processing methods used in the research were descriptive analysis, chi-square, IPA, CSI, and gap analysis. The final result of the decision making process was that visitors feel satisfied with the facilities and services. The IPA analysis showed that there was one attribute that must be improved, namely the availability of parking spaces. The level of visitor satisfaction resulted from CSI analysis was 77.21% and was included in the satisfied category. The gap analysis showed that three attributes had met visitor satisfaction, while eleven attributes had not met visitor satisfaction. There are two main recommendations from the research results for managers, namely improvements to public facilities and information facilities.

Judul: Visitor satisfaction analysis in Situ Gunung Park, Mount Gede-Pangrango National Park
Abstrak: Permintaan pariwisata yang meningkat setiap tahun menyebabkan sektor pariwisata di Indonesia menempati urutan kelima penyumbang devisa negara terbesar. Situ Gunung Park merupakan salah satu tempat wisata alam di Jawa Barat yang berlokasi di dalam kawasan Taman Nasional Gunung Gede-Pangrango, Sukabumi. Tujuan penelitian ini adalah mengevaluasi kepuasan pengunjung dengan analisis kepentingan-kinerja dan indeks kepuasan konsumen untuk meningkatkan fasilitas dan pelayanan bagi pengunjung. Selain itu, analisis model persamaan struktural dilakukan untuk melihat hubungan antar peubah laten dan antara peubah laten dengan peubah indikatornya. Pengunjung yang datang ke tempat wisata didominasi oleh pelajar atau mahasiswa yang berusia 15-23 tahun. Pengunjung berasal dari Sukabumi dan datang bersama teman atau keluarga. Berdasarkan diagram analisis kepentingan-kinerja, indikator kondisi jalan di tempat wisata, kelengkapan sarana dan prasarana, fasilitas toilet, dan pusat informasi masuk ke dalam kuadran I sedangkan indikator kebersihan, kenyamanan, dan keamanan masuk ke dalam kuadran II. Secara keseluruhan, pengunjung cukup puas terhadap fasilitas dan pelayanan yang diberikan oleh pengelola Situ Gunung Park. Uji kebaikan suai untuk model persamaan struktural sudah memenuhi nilai yang disarankan sehingga menunjukkan model sudah fit. Hubungan antar peubah yang signifikan adalah hubungan antara peubah reliability, yaitu kenyamanan dan kemudahan mencapai Situ Gunung Park, dengan kepuasan dan peubah laten kepuasan dengan loyalitas., The increasing of tourism demand in Indonesia has placed its sector become the fifth of the highest sectors that contribute for national income of the government. One of the most popular tourism objects is ecotourism which one of those sites is managed by Situ Gunung Park. Situ Gunung Park is one of the natural tourism in West Java located in Mount Gede-Pangrango National Park, Sukabumi, which provides outdoor tourism. To develop its facilities and services for visitors, visitor satisfaction evaluation using the Importance-Performance Analysis and Customer Satisfaction Index is used. Structural equation models was performed to see the relations between every latent variables and between latent variables and indicators variables. The visitors who come to Situ Gunung Park are dominated by student and collegers aged 15-23 years old. Mostly visitors came from Sukabumi and they came with their friends or families. Based on The Importance-Performance Analysis, the indicators of toilet and information center are in the first quadran while the indicators of cleanness, comfort, and security are in the second quadran. Overall, the visitors feel quite satisfied with the facilities and services given by Situ Gunung Park. Goodness-of-fit test for structural equation models is fit and can be used for the minimum requirements of this model. The relationships of significant variables are relations between reliability variables, which is comfort and easiness to Situ Gunung Park, with satisfaction variable and satisfaction variable with loyalty variables.

Judul: Mathematical model of Hematopoietic Stem Cell in Chronic Myelogenous Leukemia with and without Therapy
Abstrak: Leukemia or blood cancer is a diverse group of neoplastic disease, characterized by the multiplication of abnormal leukocytes or malignant transformation of blood-forming cells in bone marrow and lymphoid tissues. One of the most common types of leukemia is Chronic Myelogenous Leukemia (CML), which is usually diagnosed by the presence of certain chromosomal abnormalities, the so-called Philadelphia chromosome (Ph). One of the treatments of CML is Granulocyte Colony-Stimulating Factor (G-CSF). In this paper, we discuss two Hematopoietic Stem Cell (HSC) models, i.e. HSC without treatment and HSC with G-CSF treatment. The model of HSC without treatment included three equations representing the dynamics of HSC, leukocyte and platelet. Whereas, the model of HSC with G-CSF treatment includes the previous three equations and adds two more equations representing G-CSF injection and G-CSF circulation. The stability behavior of the system approaching the equilibrium points in the simulation study is carried out using Mathematica 7.0. The simulation results show that the G-CSF treatment can successfully decrease the number of HSC, which means reducing the CML.
