"Purple sweet potato is rich in anthocyanin giving a potential application in food product development. However, anthocyanin is relatively unstable and easily degraded during processing and storage. Understanding the stability and bio-accessibility of anthocyanin during processing, storage and simulated digestion is very important. The study aimed to investigate changes in anthocyanin degradation during processing, storage and simulated digestion of purple sweet potato pasta. The pasta was prepared through several processing steps, i.e. steaming the tuber, steaming the dough formula, extrusion, drying and boiling. Anthocyanin was analyzed at every stages of processing and storage of the pasta. The durability of the pasta during storage was analysed using an accelerated shelf-life testing method at 30, 40 and 50ºC for 28 days. The study showed that anthocyanin content decreased during the whole stages of processing and storage, but slightly increased during steaming. The highest loss of the anthocyanin occurred in the boiling process. Based on resistance to stomach and intestinal conditions, the bio-accessibility of anthocyanin was better in the digestive system in the stomach than that in the intestines. The increased anthocyanin appeared again in the colon. This study provides useful information for designing an effective method to minimize an extensive loss of anthocyanin of purple sweet potato for food product development."

"ABSTRAKPenggunaan bioteknologi untuk menghasilkan produk rekayasa genetik dalam bidang pangan, dikarenakan kekhawatiran atas ketidakmampuan petani tradisional menghasilkan pangan yang cukup diakibatkan faktor-faktor seperti pertumbuhan penduduk, perubahan iklim, kegiatan alih fungsi lahan dan lainnya. Penemuan tersebut diharapkan dapat membatu produsen pangan khususnya petani melalui bibit GMO, untuk dapat meningkatkan produktifitas dan menghasilkan keuntungan yang tinggi bagi mereka. Akan tetapi dalam beberapa kasus penggunaan GMO banyak menimbulkan dampak buruk bagi lingkungan, kesehatan manusia yang kemudian akan merugikan petani. Dengan keadaan seperti ini, prinsip kedaulatan pangan sebagai prinsip sistem pangan yang diadopsi di Indonesia, harus diterapkan untuk memastikan bahwa setiap individu terpenuhi hak dasarnya atas pangan dan juga memberikan perlindungan bagi petani-petani untuk memproduksi pangan sesuai dengan potensi sumber daya lokal. Skripsi ini mencoba untuk mengkaji secara normatif perlindungan hukum terhadap proses produksi hingga distribusi terkait penggunaan GMO yang ditinjau dari prinsip kedaulatan pangan. Hasil penelitian dalam skripsi ini menunjukan bahwa penggunaan GMO belum mewujudkan kedaulatan pangan baik bagi konsumen maupun produsen. Untuk itu, Pemerintah sebelum memberikan izin edar produk GMO, harus bertindak lebih hati-hati dalam membuat kebijakan atas ketidakpastian atas dampak dari penggunaan GMO.

ABSTRACTThe use of bio technology produces genetically modified foods, started with human needs to fulfill their basic rights of food, due to concern the inadequacy of traditional farmers produces enough food caused by some factors such as population growth, climate change, land use change and others. This finding is expected to help food producers especially traditional farmers with GMO seeds to help increase their productivity and improve their profits. However in certain cases, the use of GMO seeds caused many adverse effects to environment and human s health which then harming these farmers. With this situation, the principle of food sovereignty as the principle of food system that is adopted by Indonesia, should be applied to ensure that every individuals has their basic rights of food fulfilled and also to protect farmers to produce foods in accordance with potential local resources. This thesis tries to study normatively law protection of food production process in relation to distribution to the use of GMO seeds from the perspective of food sovereignty principle. The result of this research show us that the use of GMO has yet to realize proper food sovereignty to both of consumers and producers. Thus, before authorizing GMO products, the government should act more carefully in making policy on the uncertainty of the impact of the use of GMO."

"Food production, particularly rice, has been one of the major concerns in Indonesia. Primary threats to production include agricultural land conversion and climate change. In this paper, a GIS-based approach is presented to assess agricultural drought. This approach was developed using the water balance technique, which accounts for spatial population data. We found that agricultural fields in the Upper Bengawan Solo basin were fairly vulnerable to drought, mainly due to expanding Surakarta (Solo) city."

"Beras berwarna memiliki nutrisi lebih baik karena mengandung pigmen antosianin. Kandungan antosianin beras dipengaruhi oleh pemaparan iradiasi sinar gama dan masa penyimpanan. Pemaparan iradiasi sinar gama dapat menginduksi radikal bebas sehingga memicu sintesis antosianin atau memutus ikatan glikosidik antosianin. Kandungan antosianin juga dapat teroksidasi selama masa penyimpanan. Pemaparan sinar gama pada enam beras hitam dan merah dengan variasi dosis 0, 2, 5, 10, 20, dan 30 kGy serta disimpan selama 6 bulan. Antosianin dianalisis menggunakan metode perbedaan pH. Hasil pemaparan iradiasi sinar gama menyebabkan peningkatan kandungan antosianin tertinggi pada beras hitam yaitu Botanik (50,264 menjadi 82,743 mg/100g) dan Jatiluwih (15,697 menjadi 32,228 mg/100g). Beras hitam lainnya mengalami penurunan antosianin terendah yaitu Hariku (27,553 menjadi 14,110 mg/100g), Seblang Banyuwangi (33,481 menjadi 13,943 mg/100g), dan Jawa Melik (53,353 menjadi 31,060 mg/100g). Pada beras merah, kandungan antosianin tertinggi yaitu Cempo Sleman (1,252 menjadi 20,539 mg/100g), Seblang Banyuwangi (2,672 menjadi 17,867 mg/100g), Jatiluwih (2,254 menjadi 43,000 mg/100g), Bronrice (6,680 menjadi 19,287 mg/100g), PK Sundakala (1,085 menjadi 20,289 m/100g), dan Healthy Choice (2,004 menjadi 23,044 mg/100g).

Colored rice has better nutrition because it contains anthocyanin pigments. The anthocyanin content of rice is influenced by exposure gamma radiation and storage time. Gamma radiation exposure can induce free radicals, triggering anthocyanin synthesis or breaking anthocyanin glycosidic bonds. Anthocyanin content can also be oxidized during storage. Six varieties of black and red rice were exposed to gamma radiation at doses of 0, 2, 5, 10, 20, and 30 kGy, followed by a 6-month storage period. Anthocyanins were analyzed using the pH difference method. The results of gamma radiation exposure caused the highest increase anthocyanin content in black rice, namely Botanik (50.264 to 82.743 mg/100g) and Jatiluwih (15.697 to 32.228 mg/100g). Other black rice varieties experienced the lowest decrease in anthocyanin, namely Hariku (27.553 to 14.110 mg/100g), Seblang Banyuwangi (33.481 to 13.943 mg/100g), and Jawa Melik (53.353 to 31.060 mg/100g). The highest red rice anthocyanin content was in Cempo Sleman (1.252 to 20.539 mg/100g), Seblang Banyuwangi (2.672 to 17.867 mg/100g), Jatiluwih (2.254 to 43.000 mg/100g), Bronrice (6.680 to 19.287 mg/100g), PK Sundakala (1.085 to 20.289 mg/100g), and Healthy Choice (2.004 to 23.044 mg/100g). Anthocyanin Storage for 6 months tended to increase anthocyanin content in both black and red rice."
