Judul: Agrotourism Landscape Planning for Coffee Plantations in Purwabakti Village Pamijahan District Bogor Regency West Java.
Abstrak: Desa Purwabakti yang terletak di Kecamatan Pamijahan, Kabupaten Bogor, Jawa Barat, masuk dalam 75 besar desa wisata terbaik pada tahapan ajang Anugerah Desa Wisata Indonesia (ADWI) tahun 2023 karena memiliki potensi wisata alam, pertanian, dan perkebunan yang besar. Potensi budaya dan kekayaan alam yang ada di Desa Purwabakti salah satunya ada di perkebunan kopi Gunung Gagak, terletak di Dusun Cikudamulya memiliki total luas 314,73 ha. Jumlah total produksi kopi sekitar 15-25 ton untuk sekali musim panen. Namun pemanfaatan potensi khususnya disektor perkebunan kopi di Desa Purwabakti masih fokus terhadap hasil produksi dan belum dikembangkan menjadi agrowisata. Oleh karena itu penelitian ini bertujuan menganalisis kesesuaian lahan untuk kawasan agrowisata yang berkelanjutan, dan membuat rencana lanskap yang mengutamakan pengembangan agrowisata. Metode perencanaan yang dilakukan dimulai dari inventarisasi, analisis, sintesis, dan perencanaan lanskap. Analisis dilakukan pada aspek fisik, biofisik, kesesuaian lahan pengembangan komoditas, objek dan daya tarik wisata, persepsi dan preferensi, serta daya dukung. Konsep perencanaan yang digunakan adalah agrowisata berkelanjutan dengan memanfaatkan potensi alam dan budaya masyarakat. Penelitian ini menghasilkan rencana lanskap yang terdiri dari zona pengembangan agrowisata seluas 199,73 ha, dan zona non-pengembangan agrowisata seluas 115 ha., Purwabakti Village, located in Pamijahan District, Bogor Regency, West Java, was included in the top 75 best tourist villages in the 2023 Indonesian Tourism Village Award (ADWI) event due to its great potential for natural, agricultural, and plantation tourism. One of the cultural potentials and natural richness in Purwabakti Village is the Gunung Gagak coffee plantation, located in Cikudamulya Hamlet, with a total area of 314.73 ha. The total coffee production is around 15-25 tons per harvest season. However, the utilization of potential, especially in the coffee plantation sector in Purwabakti Village, is still focused on production results and has not been developed into agro-tourism. Therefore, this study aims to analyze land suitability for sustainable agro-tourism areas and create a landscape plan that prioritizes agro-tourism development. The planning method starts from inventory, analysis, synthesis, and landscape planning. The analysis is carried out on physical, biophysical, land suitability for commodity development, tourism objects and attractions, perceptions and preferences, and carrying capacity. The planning concept used is sustainable agro-tourism by utilizing the natural and cultural potentials of the community. This research resulted in a landscape plan consisting of a 199.73 ha agro-tourism development zone and a 115 ha non-agro-tourism development zone.

Judul: Planning A Sustainable Landscape Area Of Agro-Tourism In The Region Of Gunung Leutik, Bogor
Abstrak: Indonesia as an archipelagic country has a natural potential to be developed as a tourism attraction development. One of the tourism potential that can be developed is agro- tourism. Bogor region has an agricultural land managed by the unit of society and agriculture corporate. One of the farming community center is area of Gunung Leutik, Benteng Village, Ciampea, Bogor. Gunung Leutik Area Tourism has 41.4 hectares which is divided into three units, including education area of Pesantren Darul Fallah agriculture land bussiness area, and Gunung Leutik region. The existence of cultivation areas with interesting scenery, residential area and Islamic education area are potential landscape to develop as tourism object and attractions. General aim is to planning a sustainable landscape area of agro-tourism in Gunung Leutik region, that support agriculture tourism activities and environmental education. This research uses descriptive quantitative method. Quantification was performed to assess the suitability of agricultural land use for certain types of physical plant and the suitability of agricultural tourism using the land evaluation guidelines of Soil and Agro-climate Research Center of Bogor (2008). The planning approach is sustainable tourism. Stakeholder approach is carried out through stakeholder analysis derived from previous research. The main concept is to create sustainable landscape by developing agro-tourism based on physical environment to maintain its quality and increasing local communities welfare. Gunung Leutik potentially be developed as a sustainable agro-tourism area. Development of sustainable landscapes agriculture requires the integration of tourism, cultivation and education activity space. The sustainability of tourism in the region through the development of low external input sustainable agriculture (LEISA). Development of sustainable agriculture tourism is divided into tourism activities integrative zones based on the type of utilization. The zone includes : active, passive and buffer zone. Through tourism activities that involve all stakeholders make landscape ecologically and economically sustainable.

Judul: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
