Ice cream is a kind of dessert with a sweet taste and served in a cold and frozen. Ice cream has a soft texture, to make the texture required stabilizer, which is one of the ingredients added in the manufacture of ice cream in order to prevent crystallization, as a binder and improve the texture. Stabilizers can be met from starch-based materials of local potency of tubers. Gelatinization of starch in the tuber flour can replace the function of the stabilizer. Some types of tubers that can be developed as an alternative source of natural stabilizer such as porang, uwi, and taro. The study is entitled "The Effect of Adding Natural Stabilizer Based on local tubers for Improving physical and chemical properties of Red Dragon Fruit Ice Cream(Hylocereus polyrhizus sp)". This study aims to examine the effect of local tubers (lombos,flour (porang), uwi flour and belitung taro flour) as a stabilizer on manufacture dragon fruit ice cream. The research will be done first with the preparation stage which is the manufacture of tuber flours (porang, uwi and Belitung taro). Implementation of the research was conducted in two stages are 1) making dragon fruit ice cream with tuber flours; 2) determining the best treatment of the use of stabilizer from the tubers. The tests include the physical and chemical quality that has been performed in the Quality Control Laboratory, the Chemical Laboratory and the Food Biochemistry and the Food Processing Laboratory. Parameters observed in this study include moisture content, total dissolved solids, melting time, emulsion stability, and texture. Based on the results of the research known that the best treatment is the use of porang stabilizer with 0.5% concentration in the manufacture of red dragon fruit ice cream. The treatment is able to match the ability of CMC as an ice cream stabilizer. In the treatment porang 0.5% obtained water content 64.39%, total soluble solids 14.80%, emulsion stability 87.41%, and melting time 95.45 minutes / 100 grams.
Religion is not only a teaching that is believed, but also practiced by its followers. Religionaims to regulate relations to God, humans, and other creatures to be able to work togetherand serve as a guide for world and afterlife. The aim of this noble religion becomestarnished when many religious communities had conflict in the name of religion. Althoughconflict can not be separated from human life, it would be strange if the conflict is of areligious background that should bring peace and eliminate chaos. Religious followes whohave a long history of conflict are between Muslims and Christians. The aim of this researchis wants to see how the social relations between Muslims and Christians, as well as thepotential for conflict between the two adherents of the religion. This research is located inthe city of Mataram, where religious conflicts have occurred in this city. The conflictbetween Muslims and Christians in Matatam occurred on January 17, 2000, which wasfinally called the Satu Tujuh Satu conflict (171). This research uses qualitative methods, andthe instruments are observation, interviews, and documentation. The results of this study arethe social relations between Islam and Christianity in Mataram quite well established. Thisis characterized by each religion interacting well in the social sphere such as at work,markets, schools and on campus. The potential for conflict in Mataram is economicinequality, low levels of community literacy, Christianization issues and other socialproblems such as garbage, and juvenile delinquency.
This study examines the impact of social interactions of the Sasak transmigrants community in Dompu County Manggelewa. The release of transmigrants in this transmigration areacertainly has the process of adaptation and assimilation of both communities, both migrants and local communities. The method of research used is to use a qualitative approach. Datacollection is done through observation, in-depth interview (Indept interview) and FGD. FGD is used to complement the results of observation and interviews in depth. Data analysis is conducted through three phases of data reduction, classification and draw conclusions based on the overall data. The results of the research of local people and Sasak transmigrants have an equivalent interaction pattern, which tends to be associative. This can be seen from the social relations between Sasak migrant citizens with local people in various social activities that take place. Although between these two groups of people has a different social background that includes language, customs and political opportunities, they remain equal interactions. Assimilation and Acculturas are indicated by the habit of the two groups because it is vulnerable to a long time. The existence of Sasak migrant citizens in Manggelewa for a long time has made the two communities to adapt to each other. As in the event of a resident of Sasak migrant citizen with local people who choose to define newhabits. The habit formed is the unification of two or more assimilated cultures.
The study aimed to analyze the effect of using some local tuber flour as alternative stabilizer on dragon fruit ice cream through physical and sensory quality. Tuber local utilizing was lombos (porang), meanwhile uwi, talas belitung, and CMC as a control. The research was conducted in three stages: 1) making of flours: lombos, porang, and talas belitung 2) making dragon fruit ice cream in addition of natural stabilizer of lombos flour, porang flour and talas belitung flour under various concentration levels at 0.1, 0.3 and 0.5% w / v and 3) determining of the best treatment from each natural stabilizer. The result showed that was red dragon fruit ice cream with 0.5% porang flour as stabilizer had similar effect to CMC as an ice cream stabilizer. The porang 0,5% treatment was overrun, 87,41% emulsion stability, melting time 95,45 minutes / 100 gram, 54,5 dPa.s viscosity, and 3.95 hedonic score (mildly like to like), 4.33 (like) hedonic texture and 4,53 (mildly gentle to soft) texture with scoring test.Keywords: ice cream, tuber, stabilizerABSTRAKPenelitian ini bertujuan untuk menganalisa pengaruh dari penggunaan beberapa tepung umbi lokal sebagai alternatif stabilizer pada es krim buah naga terhadap sifat fisik dan sensori. Umbi lokal yang digunakan adalah umbi lombos (porang), umbi uwi dan umbi talas belitung serta CMC sebagai kontrol. Penelitian dilakukan dalam tiga tahap yaitu 1) pembuatan tepung talas belitung, pembuatan tepung umbi porang, pembuatan tepung umbi uwi, 2) pembuatan es krim buah naga dengan penambahan stabilizer alami berupa tepung umbi talas belitung, tepung umbi porang, tepung uwi pada berbagai tingkat konsentrasi yaitu 0.1, 0.3 dan 0.5 %b/v dan 3) penentuan perlakuan terbaik dari masing-masing penggunaan penstabil alami. Berdasarkan hasil penelitian diketahui bahwa es krim buah naga merah yaitu jenis penstabil porang dengan konsentrasi 0,5% dan mampu menyamai CMC sebagai penstabil es krim. Pada perlakuan porang 0,5% diperoleh overrun 68,50%, stabilitas emulsi 87,41 %, waktu leleh 97.7 menit/100 gram, viskositas 54.5 dPa s, skor hedonik rasa 3,95 (agak suka mengarah ke suka), hedonik tekstur 4,33 (suka), skoring tekstur 4,53 (agak lembut mengarah ke lembut).Kata kunci: es krim, umbi, stabilizer
Tablighi Jamaat's (TJ) proselytizing activity has had a significant impact on improving the religious practices of the community not only in India, where TJ was born and evolved, but also in other nations where they preach, including Indonesia. TJ's da'wah has reached rural places with strong customs. The purpose of this study is to investigate the growth and influence of TJ's da'wah movement in the Wetu Telu Bayan indigenous community in North Lombok. This study employs qualitative data collection approaches such as participant observation, in-depth interviews, and focus group discussions. According to the findings of this study, the beginning of TJ's da'wah expansion began with the movement of young people from the hamlet who were still in high school to Jamaah Tabligh's da'wah. He was successful in enticing the community to join by presenting various programs such as Safari Friday (Safari Jumat), a three-day church for spiritual growth. This program was strengthened by the Lombok Uatara Regent's program, namely emotional treatment (Termos) through khuruj, particularly Haji Bakrie, who is also a Tablighi Jamaat figure. This approach is highly effective and has a significant impact on the religious reformation in the Bayan customary region. Another study indicates that TJ members have successfully negotiated their teachings with traditional practices. The society began to renounce traditional practices that were seen incompatible with Islamic teachings.
