"Nepenthes tergolong tumbuhan karnivora yang tersebar luas di Indonesia. Pulau Sumatra memiliki keanekaragaman Nepenthes tertinggi kedua setelah Borneo. Penelitian bertujuan untuk mengetahui keanekaragaman jenis Nepenthes di Provinsi Sumatra Utara dan Sumatra Barat, termasuk distribusi, populasi, kondisi habitat, konsentrasi unsur hara dan status konservasinya. Eksplorasi dilakukan untuk inventarisasi jenis-jenis Nepenthes yang ditemukan di setiap lokasi penelitian, purposive sampling plot dibuat untuk mempelajari ekologinya serta analisa unsur hara pada Nepenthes dilakukan di Laboratorium. Hasil penelitian bahwa, total sebanyak 33 jenis Nepenthes ditemukan di lokasi penelitian, terdiri dari 22 jenis di Sumatra Utara dan 23 jenis di Sumatra Barat. Sepuluh jenis di antaranya tergolong kedalam kriteria terancam punah, mengingat populasi dan distribusinya sangat terbatas. Nepenthes berasosiasi sangat kuat dengan jenis vegetasi dominan di habitatnya. Pada satuan yang sama (%), konsentrasi nitrogen pada daun Nepenthes umumnya lebih besar daripada konsetrasi pada cairan kantong, sedangkan konsentrasi Nitrogen pada daun Nepenthes tidak dipengaruhi dengan bertambahnya ketinggian tempat hidupnya.

Nepenthes are classified as carnivorous plants with their distribution center in Indonesia. The island of Sumatra has the second highest diversity of Nepenthes after Borneo. The research aims to determine the diversity of Nepenthes species in North Sumatra and West Sumatra Provinces, including distribution, population, habitat conditions, nutrient concentrations and conservation status. Exploration was carried out to inventory the species of Nepenthes found at each research location, purposive sampling plots were made to study their ecology and nutrient analysis of Nepenthes was carried out in the laboratory. The results showed that a total of 33 species of Nepenthes were found at the site, consisting of 22 species in North Sumatra and 23 species in West Sumatra. Ten of these species are classified as endangered, considering that their population and distribution are very limited. Nepenthes is very strongly associated with the dominant vegetation species in its habitat. In the same unit (%), the nitrogen concentration in Nepenthes leaves is generally greater than the concentration in the pitchers fluid, while the nitrogen concentration in Nepenthes leaves is not affected by increasing the altitude at which it lives."

"Karhutla di Provinsi Riau selalu menjadi sorotan karena ulah manusia yang menyebabkan kerusakan ekosistem hingga kestabilan politik dengan negara tetangga. Untuk menyikapinya, Presiden memprioritaskan upaya pencegahan melalui kolaborasi multisektor antara pemerintah, swasta, hingga masyarakat. Penelitian ini bertujuan untuk menganalisis proses serta faktor-faktor yang mempengaruhi dalam kolaborasi pencegahan karhutla dengan model collaborative governance. Hasil penelitian menunjukkan bahwa proses collaborative governance secara keseluruhan sudah diterapkan meskipun diperlukan penyempurnaan pada proses dan faktor-faktor yang mempengaruhi kolaborasi. Intensitas dialog tatap muka masih rendah dan agenda pembahasan para aktor masih umum terhadap pengendalian kerhutla. Hasil sementara kolaborasi pencegahan belum terukur dengan baik sehingga egosektoral terlihat melalui berbagai program para aktor yang sifatnya mirip. Faktor-faktor yang menghambat kolaborasi adalah desain kelembagaan belum mengalokasi tugas pencegahan para aktor dengan jelas yang beresiko pada tumpang tindih kegiatan dan menurunnya transparansi kolaborasi. Anggaran pencegahan belum memadai karena Provinsi Riau belum memiliki dana alokasi khusus untuk pencegahan dan hanya bergantung pada anggaran aktor yang terlibat.

Karhutla in Riau Province has always been in the spotlight because of human activities that have caused damage to the ecosystem and political stability with neighboring countries. The President prioritizes prevention efforts through multi-sector collaboration between government, private sector, and community. This study aims to analyze the process and the factors that influence collaboration in preventing ‘karhutla’ with the collaborative governance model. The study indicates that collaborative governance process as a whole has been implemented although improvements are needed in the process and the factors that affect collaboration. Intensity of face-to-face dialogue is still low and the discussion is still on controlling ‘karhutla’. The interim results of prevention collaboration haven’t been well measured so that ego sector can be seen through various programs of actors that are similar in nature. The factors that hinder collaboration are the institutional design hasn’t allocated the task of preventing clearly so it’s risky to overlapping activities and decreasing collaboration transparency. The budget of prevention is not sufficient because Riau Province doesn’t have yet a special allocation fund for prevention and depends on the budget of the actors involved."

"The main effect of logging is to create an artificial disturbance regime resulting in canopy gaps and disturbance to soil, seedlings and the forest understory. The effects of logging on the physical environment of a lowland dipterocarp forest in Central Kalimantan are being investigated. A range of approaches are being applied to characterize these impacts. The effect of logging on cnopy cover, seedling density and soil disturbance are recorded to produce low resolution maps of the plots before and after logging. More detailed information about changes in canopy structure is determined using image analysis of hemispherical canopy photographs.

"Research related to the diversity and conflict in Indonesia to date concludes that ethnic fractionalization, as an indicator of diversity, is positively related to the level of conflict. However, this research has not included other indicators of diversity, namely ethnic polarization, which is considered better than ethnic fractionalization in explaining conflicts, especially identity conflicts. Using the National Violence Monitoring System (NVMS) data along with 2000 and 2010 Indonesia Census data, this study found that ethnic polarization and religious fractionalization contribute to the increase of identity conflict in Indonesia. Otherwise, there is no statistical proof that validates the positive relationship between ethnic fractionalization and the identity conflict in general. Furthermore, this study also shows that the degree of heterogeneity at district level significantly reduces some aspects of social outcomes, such as trust to non co ethnics, solidarity, participation in community, and perceived safety which act as a channel through which diversity affect identity conflict.

Penelitian terkait dengan keberagaman dan konflik di Indonesia hingga saat ini menyimpulkan apabila fraksionalisasi etnik, sebagai indikator dari keberagaman, berhubungan positif dengan tingkat konflik. Namun, penelitian tersebut belum memasukkan indikator lain dari keberagaman, yaitu polarisasi etnik, yang dianggap lebih baik daripada fraksionalisasi etnik di dalam menjelaskan konflik, khususnya konflik identitas. Dengan menggunakan data dari Sistem Nasional Pemantauan Kekerasan dan data keberagaman dari Sensus Penduduk tahun 2000 dan 2010, ditemukan apabila polarisasi etnik dan fraksionalisasi agama, berkontribusi terhadap peningkatan konflik identitas. Sebaliknya, tidak ditemukan bukti statistik yang dapat menjelaskan hubungan antara fraksionalisasi etnik dan konflik identitas secara umum. Selain itu, studi ini juga menemukan apabila tingkat keberagaman di suatu wilayah, berpengaruh negatif terhadap beberapa keluaran modal sosial seperti kepercayaan antar-etnis, solidaritas, partisipasi di komunitas, dan perasaan aman, yang berperan sebagai saluran yang menghubungkan keberagaman dengan konflik identitas.

"Kota-kota di Indonesia terintegrasi dengan keragaman dalam permukimannya, bahkan di kota-kota administratif di Jakarta terlihat adanya identitas tertentu dari masing-masing wilayah yang mempengaruhi kehidupan perkotaan. Untuk meningkatkan pengalaman dalam kehidupan perkotaan yakni dengan memiliki komunitas yang hidup berdampingan. Oleh karena itu, keberadaan kampung di dalam kota inilah yang membuat setiap dalam kecamatan memiliki hubungan saling ketergantungan yang mempengaruhi identitas dan aktivitasnya. Hubungan yang saling tergantung itu meliputi latar belakang sosial ekonomi, jaringan, gaya hidup, dan kemungkinan pengaruh dari teori place identity dan assemblage pada urban. Skripsi ini akan membahas studi kasus koeksistensi yang saling berketergantungan di lingkungan urban kampung dan kawasan elit yang berada di Tebet, Jakarta Selatan melalui sejarah, tipologi, dan aktivitas sosial-ekonomi yang bisa mengarahkan kemungkinan adanya dampak interdependensi dalam koeksistensi. Metode yang digunakan dalam tugas akhir ini adalah kajian literatur dengan observasi langsung.

Cities in Indonesia are integrated with diversity in their settlements, even in administrative cities in Jakarta there is a certain identity from each region that influences urban life. To enhance the experience in urban life is by having a coexisting community. Therefore, the existence of kampung within the city makes each district have a relationship of interdependence that influences their identity and activities. These interdependent relationships include socio-economic background, networks, lifestyles, and the possible influence of place identity and assemblance theories on urban areas. This thesis will discuss a case study of interdependence of coexistence within urban kampung and elite areas in Tebet, South Jakarta through history, typology, and socio-economic activities that can aim at the possibility of interdependence impacts from the coexistence. The method used in this final project is a literature review with direct observation.
