Judul: Management of Pekarangan as Improvement of Landscape Services for Settlements along Riparian Cisadane River in Tangerang City
Abstrak: Laju pertumbuhan yang tidak terkendali menyebabkan terjadinya alih fungsi lahan menjadi kawasan permukiman di kawasan riparian sungai. Diperlukan pengelolaan permukiman melalui pengembangan pekarangan. Penelitian ini bertujuan untuk mengidentifikasi karakteristik dan pengelolaan pekarangan, persepsi dan preferensi masyarakat, serta merumuskan rekomendasi pengelolaan pekarangan pada permukiman formal dan informal. Objek penelitian adalah pekarangan pada permukiman formal dan informal di riparian Sungai Cisadane Kota Tangerang. Sebagian besar pekarangan terletak di bagian depan dengan didominasi oleh tanaman Strata I dan fungsi estetika masing-masing sebanyak 54 dan 42 spesies. Indeks keanekaragaman jenis di kedua jenis permukiman termasuk dalam kategori tinggi dengan nilai rata-rata 4,1 dan 3,6. Berdasarkan hasil analisis uji korelasi, beberapa faktor berpengaruh positif dan negatif terhadap persepsi dan preferensi masyarakat mengenai pengembangan pekarangan. Rekomendasi dari penelitian ini adalah konsep pengembangan pekarangan sebagai strategi untuk meningkatkan jasa lanskap permukiman formal dan informal di riparian Sungai Cisadane melalui pengelolaan pekarangan., The uncontrolled population growth rate causes the conversion of land into residential areas in river riparian areas. Settlement management is needed through homegarden development. This study aims to identify the characteristics and management of homegarden, community perceptions and preferences, and formulate recommendations for homegarden management in formal and informal settlements. The research object is the homegarden of formal and informal settlements in the Cisadane River riparian Tangerang City. Most of the homegarden is located in front of the house with plants dominated by Strata I and aesthetic functions in formal and informal settlements with 54 and 42 species. The species diversity index in both settlements is in the high category with an average value of 4,1 and 3,6. Based on correlation test analysis, several factors affect people's perceptions and preferences positively and negatively in homegarden development. The recommendation from this research is the concept of homegarden development as a strategy to improve the formal and informal Cisadane River landscape services through homegarden management.

Judul: Analysis of Land Cover Change Impacts on The Landscape Services Quality in Cisadane Watershed Tangerang City
Abstrak: Peningkatan jumlah penduduk dan pembangunan di Kota Tangerang dapat menyebabkan dampak terhadap penurunan kualitas lingkungan. Hal tersebut akan mempengaruhi kondisi jasa lanskap khususnya di Daerah Aliran Sungai (DAS) Cisadane yang melewati kota ini. Penelitian ini bertujuan mengetahui perubahan tutupan lahan tahun 2010 dan 2020, perubahan kualitas jasa lanskap, dan rekomendasi pengelolaan di DAS Cisadane Kota Tangerang berdasarkan jasa lanskap. Indikator jasa lanskap yang digunakan adalah karbon tersimpan, keanekaragaman hayati, keindahan lanskap, pengaturan tata air, dan ameliorasi iklim. Hasil penelitian ini menunjukkan bahwa terjadi perubahan tutupan lahan sebesar 14,28%. Kebun campuran mengalami peningkatan luas tutupan lahan tertinggi sedangkan lahan pertanian mengalami penurunan luas tertinggi. Akibat perubahan tersebut, terjadi penurunan nilai jasa lanskap serta memperlihatkan kondisi yang kurang baik. Hasil analisis Strength, Weakness, Opportunity, Threat (SWOT) menunjukkan pengelolaan DAS Cisadane Kota Tangerang berada pada posisi hold and maintain. Strategi utama adalah pengelolaan secara pentahelix yang merupakan kolaborasi antara akademisi, pengusaha, pemerintah, masyarakat, dan media massa (ABCGM)., The increase of population and development in Tangerang City can have an impact on environmental degradation. This will affect landscape conditions, especially in the Cisadane Watershed that passes through this city. This study objectives are to determine land cover changes from 2010 to 2020, changes in landscape services quality, and recommendations for management strategies for Cisadane Watershed in Tangerang City based on landscape services. The indicators used for landscape services assessing are carbon stock, biodiversity, landscape beautification, water management, and climate amelioration. The results of this study indicate that there is a change in land cover as much as 14,28%. Mixed gardens has the largest increase and field land has the largest decrease. As a result, there is a decrease of landscape services and the quality of landscape services showed less good condition. The results of the Strength, Weakness, Opportunity, Threat (SWOT) analysis indicate that the management of the Cisadane Watershed in Tangerang City is in hold and maintain position. The main strategy is pentahelix management that is collaborative management between Academician, Businessman, Community, Government, and Mass-media (ABCGM).

Judul: Kajian Stabilitas Inti Super Berat dengan Nomor Atom 110 Sampai dengan 200 Menggunakan Model Inti Tetesan Cairan
Abstrak: Liquid droplets of nucleic models can be derived equations to estimate the binding energy, binding energy per nucleon, the most stable isotope, and the condition of the occurrence of spontaneous fission. The equations are then converted into a numerical equation form which is then inserted into the MATLAB programming language. Based on the results of the calculations have been carried out in this study, super-heavy nuclei will undergo spontaneous fission in the Z = 135. At Z = 135 the energy needed to create the nucleus undergoing fission or activation energy is very small at around 0:48 MeV. Above Z = 135 the activation energy is negative, it means to form a nucleus with Z> 135 needed some energy. Then at Z = 135 the ratio Z2 / A is 48.86, almost reaching requirement ratio Z2 / A where the nucleic will undergo spontaneous fission is 49. Binding energy per nucleon for super-heavy nuclei up to Z = 200 is about 7 - 5.5 MeV, together with a range of light nuclei are stable. So there may be a super-heavy nuclei are stable at Z <135 and above Z> 135 there will be no stable nucleic
