Judul: Changes in Staple Food Consumption as a Community Adaptation Process in Facing Climate Change (Case: An RT in a Traditional Village, South Cimahi Sub-district, Cimahi City
Abstrak: Sistem pangan masyarakat Indonesia tidak dapat lepas dari pengetahuan lokal dalam praktik sistem pertanian yang diadopsi oleh suku tertentu yang diterapkan secara turun-temurun antar generasi. Perubahan iklim menjadi tantangan dalam pemenuhan kebutuhan pangan yang dapat mengancam ketersediaan pangan pada komunitas adat tertentu. Penelitian ini bertujuan untuk menganalisis perubahan pangan pokok dan faktor yang menyebabkan perubahan konsumsi pangan pokok pada sebuah komunitas di Kampung Adat yang terletak di Kota Cimahi yang memiliki bentuk kearifan lokal berupa budaya mengkonsumsi pangan singkong. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif yang dilengkapi data kualitatif melalui metode kuesioner dan wawancara mendalam dengan responden sebanyak 50 orang yang dipilih melalui teknik simple random sampling. Hasil penelitian menunjukkan bahwa mulainya terdapat perubahan konsumsi pangan pokok pada komunitas adat berupa mengkombinasikan antara rasi dan beras padi yang disebabkan oleh faktor adaptasi berupa ancaman ketersediaan pangan singkong. Walaupun mulai terdapat perubahan, mayoritas masyarakat masih menyukai rasi untuk dikonsumsi yang disebabkan oleh adanya nilai-nilai yang diturunkan para leluhur sehingga masyarakat memilih mempertahankan budaya mengkonsumsi rasi., The food system of the Indonesian people cannot be separated from local knowledge in agricultural system practices adopted by certain ethnic groups which are passed down from generation to generation. Climate change is a challenge in meeting food needs which can threaten food availability in certain indigenous communities. This study aims to analyze changes in staple food and the factors that cause changes in staple food consumption in the community in Traditional Village, Cimahi City which has a form of local wisdom in the form of a culture of consuming cassava food. The method used in this study is a quantitative method equipped with qualitative data through a questionnaire method and in depth interviews with 50 respondents who were selected through a simple random sampling technique. The results of the study indicated that there was a change in staple food consumption in indigenous communities in the form of a combination of rasi and rice which was caused by adaptation factors in the form of threats to cassava food availability. Even though there have been changes, the majority of people still prefer rasi to be consumed due to the values passed down from their ancestors so that the community chooses to maintain the culture of consuming rasi.

Judul: Sikap dan Perilaku Konsumsi Masyarakat terhadap Beras Padi (Oryza sativa) dan Beras Singkong (Manihot esculenta) sebagai Bahan Pangan Pokok (Kasus Masyarakat Kampung Cireundeu, Kelurahan Leuwigajah, Kecamatan Cimahi Selatan, Kota Cimahi, Provinsi Jawa Barat
Abstrak: Indonesia has a high proportion of household, which have deficit food energy in every provinces, that is why diversification is needed, even become one of the main pillars in achieving the food security. However, in fact, Indonesian people are still depended on the rice paddy. Changing people's behavior in consuming the rice paddy is not easy, it is needed to learn first about how people's attitudes towards staple’s food of the rice paddy and the non rice paddy. That is because the attitudes can influence behavior. This study investigated the attitude and consumption behavior of Cireundeu Village community between the rice paddy and rice cassava. Some people of Cireundeu village have been consumed rice cassava as their staple food. Based on those case, people’s attitudes and consumption behavior can be interesting to be used as the implementation learning of food security or food diversification in other areas. The method used in this study are quantitative and supported by qualitative data. Quantitative data collected by interviewing peoples with questionnaires. The results of this study indicated that the group of respondents that consume rice paddy tended to have a positive attitude towards the rice paddy and a neutral attitude towards rice cassava. While the group of respondents who consume rice cassava and the group of respondents who consume both staple food have a tendency to a neutral attitude to both. However, attitudes toward food staples did not correlate consumption behavior, that’s meaning attitude did not determine the consumption behavior.

Judul: Sintesis dan Pencirian Senyawa 4-Dodekanadioilbis(1-fenil-3-metil-5-pirazolon) sebagai Ionofor untuk Penentuan Ion Lu3+ dengan Teknik Elektrode Selektif Ion
Abstrak: Ion selective electrode (ISE) as an alternative potentiometric method is used widely in determining Lu3+. The success of this method depends on the ionophor used on the ISE. The compound of 4-dodecanedioylbis(1-phenyl-3-methyl-5-pyrazolone) or H2DdBP as pyrazolone derivatives will be used as ionophor on ISE-Lu3+. H2DdBP had been successfully synthesized by Jensen’s method. This method involved reaction of 1-phenyl-3-methyl-5-pyrazolone and dodecanedioyl chloride in basic condition. A compound was produced as a solid substance and was purified by recrystallization using chloroform-ethanol. High performance liquid chromatogram showed that the compound was pure. The compound was in keto form with melting point range of 150-152ºC. Infrared spectra showed vibration peaks (cm-1) were 3451 (br, OH), 1624 (s, C=O), 1589 (s, phenyl C=C), 1558 (s, pyrazolone ring). Chemical shifts (Hz) for 1H-NMR were 7.81–7.84, 7.43–7.46, 7.26–7.290 (m, 10H, Ph); 2.72–2.75 (t, 4H, (CH2)2); 2.47 (s, 6H, CH3); 1.71–1.76 (m, 4H, (CH2)2); 1.32 (m, 12H, (CH2)6). All of these properties showed the characteristics of H2DdBP. Nernst factor of ISE-Lu3+ for two repetitions were 10.40 mV/decade and 8.60 mV/decade which showed that ISE-Lu3+ had good response in determining Lu3+.
