Judul: Adaptive Strategies of Small Scaled Gillnet  Fisheries at Morodemak Coast Fishing Port, Demak Regency to Extreme Weather  at Sea
Abstrak: Peningkatan frekuensi kejadian cuaca ekstrim mempengaruhi sektor perikanan. Nelayan kecil dari perikanan jaring insang di Morodemak termasuk kelompok yang mengalami dampak buruk dari cuaca ekstrim sehingga Pemerintah Kabupaten Demak perlu melakukan upaya untuk membantu mereka menghadapi kondisi tersebut. Pemerintah daerah perlu mempertimbangkan tingkat ketangguhan nelayan, dalam menentukan kelompok sasaran, jenis dan volume bantuan yang akan disalurkan. Tingkat ketangguhan ditentukan oleh kemampuan beradaptasi pada saat kegiatan penangkapan ikan sulit dilakukan. Penelitian ini bertujuan menjelaskan fluktuasi kondisi laut dan cuaca, pola adaptasi nelayan jaring insang, menginventarisasi tindakan Pemerintah, dan menyusun rekomendasi strategi bantuan. Penelitian ini menggunakan data yang dikumpulkan melalui wawancara nelayan, dan mengunduh data satelit curah hujan dan kecepatan angin dari Power Data Access Viewer. Analisis dilakukan untuk menentukan periode waktu terjadinya cuaca ekstrim, modus adaptasi nelayan, akar permasalahan dan mengidentifikasi strategi terbaik dalam memberikan bantuan. Hasil penelitian menunjukkan aktivitas penangkapan nelayan jaring insang Morodemak sangat dipengaruhi oleh kondisi laut dan cuaca. Cuaca ekstrim menyebabkan jumlah trip operasi berkurang drastis dan nelayan kehilangan pendapatan. Nelayan jaring insang Morodemak cenderung melakukan pola adaptasi negatif, berhutang dan menjual/menggadaikan aset. Selain melakukan tindakan mitigasi, respons Pemerintah Kabupaten Demak sebaiknya mencakup implementasi program yang bersifat membangun adaptasi nelayan agar semakin tangguh dalam menghadapi cuaca ekstrim, More occurrence of extreme weather seriously affects fishing activities. Fishers of the small scaled gillnet fisheries in Morodemak are among the most affected. The Demak Regency Government has responded with mitigation effort that includes provision of assistance when they experience this bad condition. The Government need to consider their resilience to the extreme weather in determining prioirity target, types and volume of assistance. This study aims to describe the occurrence and periods of extreme weather at sea, adaptation patterns of the fishers, inventory of government actions, and identify strategic recommendations to improve their resilience. Data were collected by conducting interviews, downloading satellite data of rainfall and wind speed from the Power Data Access Viewer. A number of analysis were carried out to determine frequency and time of occurrence of extreme weather at sea, modus of adaptive actions, problem analysis, advantages/disadvantages analysis of assistance and opportunity for improving resilence of the fishers. The results showed that the activities of the small scaled gillnet fisheries are sensitive to the extreme weather. In the event of extreme weather which may take several days to two weeks, number of fishing trips and their income dropped drastically. Their adaptive strategies include borrowing money and selling or pawning their belongings. In addition to mitigation effort, the Demak Regency Government's program must also include adaptive strategies to improve of resilience of the fishers to the extreme weather.

Abstrak: Dampak perubahan iklim seperti meningkatnya permukaan air laut, bertambahnya intensitas terjadinya gelombang pasang, serta terjadinya hujan yang disertai dengan angin kencang berakibat pada terhentinya kegiatan nelayan untuk melaut. Hal tersebut mengharuskan para nelayan melakukan strategi adaptasi guna mencukupi kebutuhan hidupnya. Persepsi nelayan terhadap dampak perubahan iklim dapat memengaruhi bentuk adaptasi yang mereka pilih. Adapun tujuan penelitian ini adalah untuk menganalisis persepsi dan faktor-faktor yang memengaruhi persepsi nelayan terhadap dampak perubahan iklim, menganalisis strategi adaptasi nelayan dalam menghadapi dampak perubahan iklim, serta menganalisis pengaruh persepsi terhadap dampak perubahan iklim pada strategi adaptasi nelayan. Metode penelitian yang digunakan dalam penelitian ini, yaitu metode survei dengan menggunakan pendekatan kuantitatif yang dilengkapi oleh data kualitatif. Data kuantitatif diolah menggunakan uji regresi linear sederhana dengan pemilihan responden yang menggunakan teknik clustered random sampling dengan jumlah responden 45 orang., The impacts of climate change such as rising sea levels, increasing intensity of tidal waves, and rain accompanied by strong winds have resulted in the cessation of fishing activities. This requires fishermen to carry out adaptation strategies to meet their daily needs. Fishermen's perception of the impacts of climate change can influence the form of adaptation they choose. The purpose of this study is to analyze perceptions and factors that influence fishermen's perceptions of the impact of climate change, analyze fishermen's adaptation strategies in dealing with the impacts of climate change, and analyze the effect of perceptions on the impact of climate change on fishermen's adaptation strategies. The research method used in this study is a survey method using a quantitative approach which is complemented by qualitative data. Quantitative data was processed using a simple linear regression test with the selection of respondents using clustered random sampling technique with a total of 45 respondents.

Judul: Prenilasi Senyawa β-Diketon sebagai Prekursor 3-Prenilflavon
Abstrak: One group of flavonoids that has not been commonly synthesized is 3- prenylflavone. The main objective of this experiment was to synthesize precursor of 3-prenylflavone. Firstly, β-diketone was synthesized via 4 steps from phenol as starting compound with total yield of 24%. Prenylation of β-diketone with prenyl bromide and K2CO3 base produced 4 fractions which were separated by using preparative thin layer chromatography (PTLC) with n-hexane:EtOAc (8:2) as the eluent. Fraction with Rf = 0.80 was further separated by using preparative PTLC with n-hexane:EtOAc (99:1) as the eluent. Two fractions were obtained with Rf = 0.38 and 0.42. The first fraction has been characterized as diprenylated β-diketone with 49% yield. Application of protecting group on the phenolic OH group in β- diketone are needed to obtain monoprenylated β-diketone which can be further cyclized into 3-prenylflavone
