Abstract

Karotenoid, fukosantin dan fenol merupakan senyawa yang terkandung pada rumput laut Sargassum duplicatum. Senyawa-senyawa ini berperan dalam menghambat radikal bebas. Namun, kemampuan penghambatan radikal bebas senyawa ini mempunyai kestabilan yang rendah, terutama terhadap perlakuan suhu. Tujuan penelitian ini adalah untuk menentukan pengaruh pre-treatment suhu tinggi (blanching) dan suhu rendah (pembekuan) serta perlakuan terbaik yang dapat mempertahankan stabilitas senyawa aktif pada ekstrak metanol rumput laut selama penyimpanan. Metode penelitian yang digunakan adalah experimental laboratories menggunakan rancangan acak lengkap (RAL) faktorial 2x5 yaitu pola terbagi menjadi faktor suhu pengolahan (suhu tinggi dan suhu rendah) dan lama penyimpanan (0, 2, 4, 6, dan 8 hari). Blanching dilakukan pada suhu 95 oC sedangkan pembekuan pada suhu -27 oC. Hasil penelitian menunjukkan karotenoid, fukosantin, dan senyawa fenol dengan perlakuan blanching lebih stabil dibandingkan perlakuan pembekuan. Berdasarkan hasil penelitian menunjukkan bahwa adanya interaksi antara pre-treatments dan lama penyimpanan yang berpengaruh nyata terhadap nilai total karotenoid, kandungan fukosantin, total kandungan fenol, dan nilai perubahan warna (ΔE).

Abstract

This study aims to determine: (1) the effect of risk-related information on risk perception; (2) the effect of risk perception on travel anxiety; (3) the effect of travel anxiety on travel intentions; (4) the effect of related information on travel intentions. The research used is descriptive analysis research with a quantitative approach and assisted by the SmartPLS program. Collecting data by distributing questionnaires with google form. The population in this study were all domestic tourists in Indonesia. The sampling technique used is accidental sampling. The sample is 403 respondents. The results showed that: (1) Information related to risk affects the perception of risk; (2) Perceived risk has a significant effect on travel anxiety; (3) Travel anxiety has a significant effect on travel intentions; (4) Information related to risk has a significant effect on travel intentions. Overall, risk-related information has an important role in influencing tourists' travel intentions. Thus, the role of risk-related information as an external factor becomes important in influencing the psychological factors of tourists during the COVID-19 pandemic. It is hoped that the government can make considerations in rebuilding tourism activities in Indonesia through policies that can support business people and protect the health of tourists and their communities. Keywords: Risk-Related Information, Risk Perception, Travel Anxiety and Travel Intention, Crises, COVID-19 Pandemics

Abstract

Four tropical fish species, Thunnus albacares (Yellowfin tuna), Ephinephelus striatus (Nassau Grouper), Cyprinus carpio (Carp), and Osphronemus gourami (Gouramy), were assayed for oxidation reduction potental (Eh) and pH in different temperature,i.e.  ambient and chilled temperature.  Every species has different pattern of Eh and pH values. Eh values of tropical freshwater fish were higher than tropical marine fish, however pH values  four tropical fish have same trend. The rates of the Eh and pH changing in four tropical fish were faster at ambient storage and they were slower at chilled storage. The present study also demonstrated the relationship between Eh and pH.

Abstract

Some traditional fish products in Indonesia have potential opportunity for global market, such as fish crackers, dried fish, ikan kayu (‘katsuobushi’) and dried pempek (traditional fish product from Palembang). Study on such products based on its glass transition temperature is still rare. On the other hand, glass transition phases of dried product play an important role in determining food stability because it can give an overview of physicochemical properties of the products. Using its glass transition temperature, dried fish product can be estimated for its shelf life. The purposes of this research are to observe the relation between some physicochemical properties of glass transition temperature of some dried fish products and its water content/water activity to the self life of the products. Dried fish products used were: fish cracker, dried-salted fish, ikan kayu (katsuobushi), fufu (very dried-smoked fish) and dried pempek. The samples were taken from different area in Indonesia (Cilacap, Palembang, and Sulawesi). The sample were taken using purposive sampling method. The method used for analysis of glass transition temperature was DSC method (Differential Scanning Calorimetry), and for water content and water activity were analysed using Aw meter and Moisture analyzer. All samples were analyzed in duplo. Research method used was experimental laboratory with research design of Completely Randomised Design. The experiment was conducted from August 2008 to December 2008 at Fish Product Processing Laboratory, Fisheries Department, Faculty of Fisheries and Marine Science – Diponegoro University, Food Engineering Laboratory – SQU, Oman. The results showed that different sample with different characteristics on physicochemical properties give different in water activity and also water content. The lowest water activity was performed by dried pempek. Glass transition temperature (Tg) of the products was very depend on the water content. The Tg of samples was ranged between 38.4oC – 76.4oC. The water content of the products ranged between 8.28%-37.28%. The Aw of the product was ranged between 0.57 – 0.87.

Abstract

AbstrakPelaksanaan mengenai perwakafan sebelum diberlakukan Peraturan Pemerintah Nomor 28 Tahun 1977 adalah banyak tersebar isu bahwa banyak tanah wakaf yang tidak sesuai dengan peruntukannya semula.Sehingga untuk mendapatkan suatu keabsahan tanah wakaf yang sudah bersertifikat, maka semua tanah wakaf yang sudah bersertifikat itu harus didaftarkan kepada Kantor Pertanahan Wilayah Kabupaten/Kotamadya setempat, khususnya Kotamadya Samarinda.        Apabila terjadi adanya perselisihan atau sengketa dalam praktek perwakafan, agar diupayakan pihak kelurahan atau desa untuk dapat menyelesaikan sengketa tersebut secara kekeluargaan, sehingga tidak sampai membawa sengketa itu ke Pengadilan.

Abstract

Tujuan penelitian ini adalah ingin menelusuri secara mendalam potensi ekonomi digital masyarakat desa pelosok dari sisi sumber daya alam, sumber daya manusia dan sarana prasarana. Penelitian ini dilaksanakan dengan pendekatan kualitatif berdasarkan penelitian lapangan. Adapun metode pengumpulan data yang digunakan adalah observari, wawancara, dan penyebaran angket. Sampel penelitian sebanyak 50 orang pelaku bisnis di usia produktif. Hasil penelitian menunjukkan pertama masyarakat desa pelosok memiliki potensi sumber daya alam yang cukup baik, hanya saja potensi ini kurang dapat dipasarkan karena belum adanya sistem pengemasan produk yang baik. Kedua masyarakat desa pelosok kurang memiliki potensi sumber daya alam, karena mayoritas penduduk masih kurang menguasai sistem transaksi online berbasis aplikasi. Ketiga dari sisi sarana dan prasarana, masyarakat desa pelosok hari ini dinilai cukup memiliki akses internet yang baik, hanya saja pada kasus desa pedalaman kendala yang cukup menyulitkan adalah sulitnya medan tempuh dengan jarak jauh sehingga bagian transportasi kurang begitu mendukung.
