Abstrak: NISSA AMALIA SIREGAR. Analisis Rantai Nilai Pengusahaan Wisata Alam PT. Fontis Aqua Vivam di Situ Gunung Taman Nasional Gunung Gede Pangrango. Dibimbing oleh SAMBAS BASUNI DAN TUTUT SUNARMINTO. Pengembangan pariwisata memiliki peran penting dalam pembangunan ekonomi daerah. Pariwisata memiliki efek pengganda yang dapat mendorong pertumbuhan sektor lain seperti perdagangan, jasa, hunian, dan tenaga kerja. Pengembangan wisata alam Situ Gunung memberikan manfaat ekonomi dan mendukung lingkungan serta budaya. Kerjasama dengan PT. Fontis Aquam Vivam (FAV) memungkinkan pengembangan ekowisata melalui partisipasi masyarakat. Pendekatan rantai nilai mengintegrasikan aktivitas wisatawan dan melibatkan masyarakat lokal, meningkatkan pendapatan mereka. Ini membuat pengembangan ekowisata di Situ Gunung berdampak positif ekonomi dan sosial pada masyarakat lokal. Pengelola Balai Besar Taman Gunung Gede Pangrango (BB- TNGGP) mencatat bahwa jumlah pengunjung ke wisata alam Situ Gunung mengalami peningkatan signifikan setelah pembangunan jembatan gantung, mencapai peningkatan sekitar 1000% dari tahun sebelumnya. Jumlah pengunjung pada tahun 2018 mencapai 158.278 orang, dibandingkan dengan 22.507 orang pada tahun sebelumnya. Penelitian dilakukan di Resort Situ Gunung, kawasan Taman Nasional Gunung Gede Pangrango (TNGGP), oleh PT. FAV pada bulan Januari-April 2023. Penelitian ini menggunakan metode deskriptif dengan memilih lima anggota rantai nilai sebagai sampel. Pendekatan ini memanfaatkan data mengenai kawasan dan daya tarik wisata. Lima anggota rantai nilai yang dipilih adalah travel agent dan angkutan lokal (biro perjalanan dan transportasi), akomodasi penginapan, Restoran Pangrango dan UMKM (restoran dan makanan), serta UMKM Souvenir (shopping). Wisata alam Situ Gunung adalah aktor objek tujuan wisata (visit experience). Teknik pengambilan sampel menggunakan snowball sampling pada masyarakat yang berdomisili di Desa Gede Pagrango, Desa Sukamanis, dan Desa Sukamaju yang berbatasan langsung dengan wisata alam Situ Gunung. Menurut data yang diperoleh yaitu pada aktor agen perjalananBumi Adventure Sukabumi (BAS) memiliki kedudukan yang mempunyai kontribusi besar dan memiliki peran penting dalam peningkatan peran rantai nilai wisata. Rantai nilai dengan derajad kerjasama yang lemah dari aspek nilai tambah penghantaran wisatawan adalah pihak UMKM Souvenir. Rantai nilai yang mendapatakan manfaat lebih banyak dari aspek ekonomi dan penghantaran wisatawan ke wisata alam Situ Gunung adalah Resto Pangrango, akan tetapi belum terbentuknya pola kerjasama yang sistematis membuat peningkatan rantai nilai tidak merata dari semua aktor. Peningkatan sistem kerjasama kegiatan wisata dari tahap awal kedatangan wisatawan sampai dengan kepulangan wisatawan akan meningkatkan rantai nilai dari semua aktor yang terlibat., NISSA AMALIA SIREGAR.

Judul: Performance of Management and Development Strategy of Natural Recreation of Situ Gunung, Gunung Gede Pangrango National Park
Abstrak: Management of natural recreation usually not equal yet with evaluation activities. Carrying out of Natural Recreation of Situ Gunung need evaluation in order to know how far satisfaction of visitor can be reached and brought into line with tourism activities in conservation area. This research aim is analysing management performance of natural recreation for gaining strategic alternatives of Situ Gunung Natural Recreation. The operationally research were bound on visitors satisfaction and on impact of tourism activities on social economic of communities and environment around the recreation place. The aspect on social economic of communities was observed from tourism impact and communities motivation on participating of recreation activities. Environmental aspect was observed from naturalism and preservation of the recreation area. Data analysis method consist of management performance analysis (descriptive analysis), visitors satisfaction analysis (Important – Performance Analysis/IPA and Customer Satisfaction Index/CSI) and Analysis of development alternatives (SWOT Analysis). Situ Gunung managed by two prominent institutions, i.e. Perum Perhutani and Bureau of Gunung Gede National Park. Man resources which behave are 4 employees of Situ Gunung Resort of Gunung Gede Pangrango National Park and 6 employees of Perum Perhutani. Access toward the location easily is reached by private vehicles or public transportation means. Situ Gunung Natural Recreation has 4 ultimate objects connected by roads that need repairing in some parts. The visitor backgrounds of dominant education are elementary school, occupations as student who came from inner side of Sukabumi itself, with recreation as arrival destination. The promotion of location is not effectively yet to these visitors. Visitor services form is recreation without tourist guide. There are in total 100 hectares area that intensively used as natural recreation activities, about 7 % area has been changed. Violation actions that probable can destroy resources are illegal logging/hunting although in small intensity. Visitors valuation of 16 attributes put into ‘SATISFACTORY’ category in CSI. It was identified 8 strengths and 8 weaknesses as internal factors and 8 opportunities and 5 threats as external environmental factors. Result of the SWOT analysis showed that Situ Gunung Nature Recreation lay in positive side of its internal and external factors with suggested development strategy is Strengths-Opportunities.

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.
