Abstrak: MUTIARA AYU WIDYAKUSUMA NINGRUM. Perencanaan Pemasangan Penanda pada Lanskap Desa Rembangkepuh sebagai Desa Produsen Tanaman Hias. Dibimbing oleh BAMBANG SULISTYANTARA Desa Rembangkepuh merupakan salah satu desa di Kabupaten Kediri yang menjadikan tanaman hias sebagai salah satu komoditas utamanya. Di desa ini, banyak masyarakat yang berprofesi sebagai petani dan penjual tanaman hias. Mereka menanam berbagai jenis tanaman hias dengan komoditas utama bunga bugenvil (Bougainnvillea sp.) dan tanaman penghijauan serta menjualnya di depan rumah. Namun keunggulan tersebut sejauh ini belum dirasakan oleh petani tersebut. Hal ini disebabkan berbagai hal, antara lain tidak adanya penanda yang menunjukkan identitas desa sebagai desa produsen tanaman hias, tidak adanya zonasi yang jelas yang dapat menunjukkan area yang dominan menanam dan menjual setiap kelompok tanaman yang dijual di desa tersebut, dan adanya pandemi COVID-19 yang menyebabkan tanaman hias menjadi sepi pembeli dan petani mengalami banyak kerugian. Oleh karena itu, perlu adanya perencanaan lanskap desa berdasarkan pemasangan penanda secara komprehensif untuk memperkuat jati diri desa sebagai sentra penghasil tanaman hias. Penelitian ini dilakukan dengan proses perencanaan yang meliputi persiapan, pengumpulan data (inventarisasi), analisis dan sintesis, konsep dan pengembangan dengan hasil akhir berupa perencanaan penanda pada lanskap desa dan rekomendasi tanaman hias introduksi untuk ditanam di Desa Rembangkepuh. Analisis dilakukan dengan mempertimbangkan kondisi desa berdasarkan aspek fisik dan biofisik, aspek sosial dan ekonomi, dan aspek bisnis. Analisis untuk perencanaan penanda dalam lanskap dilakukan menggunakan metode wayfinding. Adapun analisis untuk rekomendasi tanaman hias baru, dilakukan dengan menggunakan analisis kualitatif deskriptif.

Planning for Signage Installing in the Landscape of Desa Rembangkepuh as an Ornamental Plant Producer Village. Supervised by BAMBANG SULISTYANTARA Rembangkepuh Village is one of the villages in Kediri Regency that uses ornamental plants as one of its main commodities. Most of the people in this village work as farmers and sellers of ornamental plants. They grow various types of ornamental plants with the main commodities being bougainvillea (Bougainvillea sp.) and greenery and selling them in front of the house. However, these advantages have so far not been felt by these farmers. This is due to various things, including the absence of signage that show the village's identity as an ornamental plant producing village, the absence of clear zoning that can indicate the dominant areas for planting and selling each group of plants sold in the village, and the COVID-19 pandemic. which causes ornamental plants to become less buyers and farmers suffer a lot of losses. Therefore, there is a need for village landscape planning based on the installation of comprehensive signage to strengthen the village's identity as a center for producing ornamental plants. This research was carried out with a planning process which included preparation, data collection (inventory), analysis and synthesis, concept and development with the final result in the form of planning markers in the village landscape and recommendations for introduced ornamental plants to be planted in Rembangkepuh Village. The analysis was carried out by considering village conditions based on physical and biophysical aspects, social and economic aspects, and business aspects. Analysis for signage planning

Judul: Study Procurements and Rental of Plants at the Sentra Tanaman Hias Permata Buana Bojongsari, Depok City
Abstrak: Industri lanskap di Indonesia semakin berkembang seiring dengan munculnya berbagai perusahaan yang bergerak di bidang lanskap, salah satunya adalah nurseri. Sentra Tanaman Hias Permata Buana merupakan sebuah tempat berisi kumpulan nurseri yang menyediakan berbagai jenis tanaman, tidak hanya menjual tetapi juga menyediakan penyewaan tanaman untuk keperluan dekorasi indoor maupun outdoor. Tempat tersebut ramai dikunjungi baik oleh para pecinta tanaman hias maupun perusahaan lanskap yang mencari tanaman untuk kebutuhan lanskap, sehingga pengadaan tanaman pada nurseri perlu diperhatikan. Oleh karena itu diperlukan penelitian ini untuk menemukan kendala/permasalahan pada sistem pengadaan tanaman dan memberikan rekomendasi strategis terkait pengadaan tanaman di nurseri agar usaha nurseri dapat berkembang lebih baik dan berkelanjutan. Selain itu, penelitian ini juga bertujuan untuk mempelajari sistem penyewaan tanaman yang dapat menjadi peluang usaha baru dalam bidang tanaman. Penelitian dilaksanakan di Sentra Tanaman Hias Permata Buana Bojongsari, Kota Depok dari Bulan Januari 2023 sampai dengan September 2023. Pengumpulan data dilakukan dengan observasi langsung di lapangan, wawancara dengan pengelola dan studi pustaka. Data dianalisis secara kualitatif dan kuantitatif menggunakan metode analisis SWOT. Hasil penelitian menunjukkan bahwa sistem pengadaan tanaman di Sentra Tanaman Hias Permata Buana yang terdiri atas perbanyakan, pemeliharaan, dan penjualan masih bersifat konvensional, tetapi beberapa nurseri sudah mulai bergeser ke arah modern dimana pada beberapa nurseri sudah memanfaatkan media digital dan kemajuan teknologi. Berdasarkan pendekatan SWOT, sistem pengadaan Sentra Tanaman Hias Permata Buana berada pada kuadran I (Grow and build strategy) sehingga membutuhkan strategi seperti pengembangan penelitian, sosialisasi/edukasi, atau pengembangan usaha kedepannya. Dengan demikian, rekomendasi strategis yang diberikan untuk sistem pengadaan tanaman di Sentra Tanaman Hias Permata Buana ini berfokus untuk pengembangan pada sistem pengadaan tanaman di nurseri yaitu pengembangan upaya promosi melalui media digital, meningkatkan keterampilan sumber daya dan legalitas, dan memperluas target pasar., The landscape industry in Indonesia is growing along with the emergence of various companies engaged in the landscape sector, one of which is a nursery. Permata Buana Ornamental Plant Center is a place with a collection of nurseries that provide various types of plants, not only selling but also selling plants for indoor and outdoor decoration needs. The place is get crowded with both ornamental and landscape plant lovers who are looking for plant companies for landscape needs, so it is necessary to pay attention to the procurement of plants in nurseries. Therefore, this research is needed to find constraints/problems in the plant procurement system and provide strategic recommendations related to plant procurement in nurseries so that nursery businesses can develop better and sustainably. In addition, this research also aims to study the plant rental system which can be a new business opportunity in the field of plants. The research was conducted at the Sentra Tanaman Hias Permata Buana Bojongsari, Depok from January 2023 to September 2023. Data collection was carried out by direct field observation, interviews with managers and literature study. Data were analyzed qualitatively and quantitatively using the SWOT analysis method. The results showed that the plant procurement system at the Permata Buana Ornamental Plant Center which consisted of propagation, maintenance, and sales was still conventional, but several nurseries had started to move towards modernity

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
