Abstract

Lautan dan samudra merupakan sumber daya yang tak terbatas di mana lautan telah digunakan sebagai sarana transportasi, sumber makanan, pertambangan dan perdagangan laut serta medium proyeksi kekuatan suatu negara. Nilai penting laut dan samudera di era globalisasi ditandai dengan meningkatnya lalu lintas perdagangan laut. Sejarah membuktikan bahwa negara yang memilih lautan untuk memajukan kepentingan, mereka menjadi kuat secara politik dan makmur secara ekonomi. Indonesia sebagai kekuatan maritim yang besar telah mendominasi pusat jalur sutera di abad ke-10 sampai abad ke-14. Gagasan poros maritim Indonesia saat ini menunjukkan upaya pemerintah untuk memperkuat kekuatan nasional dan kemakmuran rakyat Indonesia berdasarkan kegiatan yang berkaitan dengan aktivitas kemaritiman. Tulisan ini menjelaskan poros maritim dari perspektif sejarah maritim dan perspektif ekonomi pertahanan. Kerangka teoritis dari A.T Mahan, J.S. Corbett, J.R. Hill dan Ken Booth digunakan untuk memahami poros maritim dalam perspektif ekonomi pertahanan. Kedua pendekatan tersebut digunakan secara bertautan di mana sejarah maritim tidak akan membantu tanpa pedoman teoritis, sedangkan teori memerlukan catatan sejarah sebagai bukti empiris untuk menggambarkan pola yang ada sebagai kerangka awal bagi pemahaman poros maritim Indonesia. Seas and oceans are endless resources used for transportation, food sources, offshore mining and sea commerce as well as medium of state’s power projection. In the era of globalization, the importance of seas and oceans is marked with the increasing of international sea commerce traffic. Furthermore, history shows that the nations choosing oceans to advance their interest became politically strong and economically prosperous. Indonesia with a great maritime power dominated the center of ancient maritime Silk Road from 10th to 14th century. The idea of maritime fulcrum in the current development, therefore, shows the government efforts to strengthen Indonesia’s national power and prosperity based on maritime activities. This paper describes maritime fulcrum from the perspectives of maritime history and defense economy. Theoretical frameworks from A.T Mahan, J.S. Corbett, J.R. Hill, and Ken Booth are used to understand the maritime fulcrum in the defense economy perspective. The maritime history will not help without theoretical guidelines and theory requires historical record as empirical evidence to draw the patterns in order to conceptualize Indonesia’s maritime fulcrum.

Abstract

Biodiesel merupakan salah satu alternatif untuk mengurangi ketergantungan bahan bakar fosil dan mengurangi dampak lingkungan. Pemanfaatan limbah ikan patin menjadi salah satu pilihan bahan baku dalam pembuatan biodiesel. Tujuan penelitian yang dilakukan yaitu memanfaatkan limbah ikan patin (jeroan) sebagai bahan baku pembuatan biodiesel. Proses pembuatan diawali dengan pencucian dan pembersihan limbah ikan. Selanjutnya, dilakukan pengambilan minyak dengan cara di oven hingga ampas limbah ikan dan minyak ikan terpisah. Minyak ikan di uji kadar FFA awal untuk penentuan tahapan selanjutnya, yaitu esterifikasi atau langsung ke tahap transesterifikasi. Proses transesterifikasi dilakukan dengan menggunakan pelarut metanol dan katalis KOH. Hasil proses transesterifikasi didekantasi untuk pemisahan biodiesel dengan gliserol. Kemudian didistilasi agar biodiesel terpisah dari sisa-sisa pengotor dan dilakukan analisis. Hasil penelitian menunjukkan bahwa pembuatan biodiesel berbahan baku ikan patin berhasil dilakukan dan senyawa metil ester menjadi komponen penyusun utama sampel biodesel yaitu senyawa 9-Octadecenoic acid (Z)-, methyl ester.

Abstract

The establishment of the Eucalyptus urophylla plantation has a potential contribution to the improvement of dryland ecosystem productivity in East Nusa Tenggara. However, the productivity of E. urophylla stand in this area is rarely documented even though it has been managed for more than 20 years. This study was directed to evaluate the growth performance, biomass accumulation, and carbon storage in E. urophylla plantation managed by Timor Tengah Selatan Forest Management Unit (FMU). Data were collected by a field survey using N-trees sampling method. Results demonstrated the mean tree density of E. urophylla in this area was 182 trees/ha with an average stand volume of 150.12 m3/ha. The mean annual increment in volume varied from 1.83 to 19.45 m3/year. The mean biomass accumulation and carbon storage in E. urophylla plantation approached 171.76 and 52.25 Mg/ha. Around 65% of total biomass and carbon storage were accumulated in the stem. Interestingly, the relative contribution of the stem to total biomass increased slowly with diameter class increasing while the dissimilar trend was observed in root, branch, and foliage. Based on the results, this study confirmed that the existence of E. urophylla plantation could increase the productivity of dryland ecosystem in East Nusa Tenggara.

Abstract

Anthropogenic activities carried out by communities around forests in production forests, protected forests, and conservation forests have an impact on changes in the land cover of these areas. This impact is difficult to avoid because, on the other hand, production forests and protected forests are in direct contact with the lives of local communities. Changes in land cover have a significant impact on the contribution of Folu Net Sink, which is set by the government at 31.89% in 2030 with its efforts. This research aims to provide an overview of land cover changes that occurred in natural forests of the Eucalyptus urophylla type from 2002 to 2022. The method used in this research is a supervised/guided digital classification technique. Ground checks were also carried out in this research to match the accuracy of the image data with the actual conditions in the field. The research results show that changes in land cover in 2012 and 2017 were very extreme. Forest fires were the cause of changes in land cover during this period. Meanwhile, in 2002, 2007, and 2022, the land cover was still good, in a positive direction. The causes of changes in land cover are encroachment activities, encroachment, illegal logging, firewood theft, rice fields, forest fires, plantations, and farming. Forest preservation provides very high benefits for life on earth. Therefore, it is important to pay attention to the welfare of local communities so that they do not damage the forest, as well as increase the capacity to educate the community regarding zoning or blocks in conservation and protected forests. Apart from that, good forest management is needed to ensure forest sustainability in the future.
