Abstract

The research identifies factors influencing consumer preferences of kasbi sago (Sagu Jay Brand) purchasing decision. It conducts in Ternate from July to December 2020. The kasbi sago from Sagu Jay Brand is produced in Jaya Village, distributed through collectors, and marketed in Ternate City. The brand is chosen because the village is a center of Sagu Jay sales with the highest consumer demand in North Maluku compared to other kasbi sago production. The research is a survey research using qualitative and quantitative methods. The qualitative aims at identifying research descriptions derived from traders in marketing the Sagu Jay product and related respondents. The qualitative data are then quantified by processing the data to generate tabulated valid data. The quantitative data are numeric or values in the variable are expressed in real numbers (Sugiono, 2014). Research variables to be observed include cultural, price, flavor, and purchase location factors. Consumer preference sampling refers to experts’ opinion that sampling used to obtain representative data is a non-probability sampling, namely accidental sampling. The research analysis method used is conjoint analysis. The research results of factors influencing consumer preferences of Sagu Jay purchasing decision in Ternate indicate that flavor factor at the original level (1.921) and the chocolate level (1.668) are dominant factors and levels that form consumer preferences. The second dominant factor is the texture factor at the dry level (0.918) followed by the price factor at the level of Rp. 10.000 (0.576), and purchase location factor at the level of Pasar Kota Baru (0.060). The lowest factor is cultural factors at regional acceptability (0.29). This suggests that the consumers prefer kasbi sago products from the Sagu Jay brand due to the flavor factor at the dry level than other factors.

Abstract

Lupane-type triterpenoid saponins are potent plants’ secondary metabolites for drug development as they showed various activities such as anticancer, Sarcoplasmic Reticulum Ca2+-ATPase (SERCA) activator which is very important for neurons, and antileishmanial. The triterpenoid saponin backbone is produced by cyclization and rearrangement of the 2,3-oxidosqualene precursor by the oxidosqualene cyclase. The type of oxidosqualene cyclase involved determines the type of saponins so it is referred to as a key enzyme. Lupane-type saponins are produced by 2,3-oxidosqualene cyclization through the chair-chair-chair conformation and the formation of various cation intermediates. This study aimed to analyze lupeol synthase, the key enzyme which determines the conversion of 2,3-oxidosqualene into lupane-type saponins.  This in silico project was done using bioinformatics programs including Multiple Em for Motif Elicitation (MEME), ProtParam, and Molecular Evolutionary Genetic Analysis (MEGA-X) for relationship analysis. The amino acid sequences analysis using the MEME program showed that lupeol synthase has QW, DCTAE, and CYCR conserved motifs in the oxidosqualene cyclase family even though some evolutions were also present. Analysis of chemical and physical parameters with ProtParam indicated that lupeol synthase had lower stability than lanosterol synthase from Saccharomyces cerevisiae. The phylogenetic tree showed that lupeol synthase was closely related to other plant oxidosqualene cyclases. The results of this study are expected to support the modification strategy determination to increase the production of lupane-type saponins using a biotechnological approach in the pharmaceutical industry.

Abstract

In daily life, the interaction of the Osing people with their agricultural environment has resulted in various activities that have local wisdom values. All of these activities are still carried out in the midst of the rapid advancement of digital and online technology-based civilization. In addition, in their social life, the community is consistent in carrying out and preserving various traditional ritual traditions from their ancestral heritage. The research aims to make an inventory of various activities that have local wisdom values and record they carry out traditional conservation of the biological resources in their environment. The research used a qualitative descriptive method, while data collection was carried out through observation and interviews in Focus Group Discussions (FGD). The data analysis process uses cross-checking, summarizing, and synthesizing. The results showed that there were various activities of the Osing community that contained local wisdom values, including farming practices using the Javanese calendar (pranotomongso) and the history of making and placing garden lands that function as buffer areas for paddy fields to prevent landslides. ancestors of the Osing tribe. The division of tasks in farming activities in the rice fields carried out by men and women of the Osing tribe reflects a combination of activities that have aspects of local wisdom. Likewise, the use of straw as animal feed and natural organic fertilizers, as well as the use of a kettle, fishing tools, the use of hunting dogs to get wild animals, and skills in the process of making traditional tools. The Osing community carries out traditional ecosystem-based conservation to protect all plants that grow on their agricultural lands. In addition, in maintaining the sustainability of clean water springs (belik) along the banks of the Sobo and Gulung rivers, they do this by making a ban on cutting down trees that grow around the riverbanks and performing the rebo wekasan salvation ritual.

Abstract

The village, which is located in the Coastal District of Jailolo, West Halmahera, had a considerable impact from the earthquake. This is because the earthquakes that occur are influenced by tectonic earthquakes due to the movement and collision of tectonic plates on land and the seabed. If the collision causes a fault in the seabed, a tsunami can occur. The purpose of this study was to analyze the risk of earthquake disasters in supporting development planning and to produce an earthquake risk map for the coastal area of Jailolo District, West Halmahera. The analytical method used is descriptive quantitative, and the data collection model is a questionnaire with random sampling. The results obtained are in the form of a hazard value using the PGA value and produce the same PGA value, namely > 0.70 gal with a high category for Bobanehena Village, Saria Village, Payo Village, Bobo Village, and Idamdehe Village. The value of vulnerability (physical, social, and economic vulnerability) shows that Bobanehena Village has a high vulnerability index value with a score of 1.9. The capacity index value for the five villages has the same score of 3 and is included in the high class. So that the value of the earthquake risk level with a high class is obtained, namely in Bobanehena Village and Bobo Village. The high level of risk in the two villages is influenced by the frequency of occurrence of earthquakes with high intensity in the area, the impact of losses due to earthquakes is quite high. Earthquake risk reduction efforts will be maximized if a comprehensive earthquake risk assessment analysis is carried out and a commitment from the Government is carried out.

Abstract

This study aims to determine the absolute viscosity value of pertalite fuel sold at gas stations and retail. The method used is an experiment with video analysis assisted by Logger Pro software. The number of retail pertalite samples tested consisted of 5 samples taken from different places. The research step is to analyze the video recorded on the motion of a falling object, namely an iron ball (Gotri) into the fluid (pertalite fuel) with logger pro software then track the video recording and obtain terminal time and speed data. From the results of the terminal velocity then it is calculated to the absolute viscosity equation. The results of the test showed that there was no significant difference between the viscosity of pertalite sold by gas stations and those sold at retail. This is evidenced by the average viscosity coefficient value of Pertalite gas stations of 0.4074 (Ns/m²) while the viscosity of retail pertalite is 0.4019 (Ns/m2). These results conclude that the pertalite sold retail in East Ogan Komering Ulu area is still maintains the quality of pertalite from gas stations so that it is safe for vehicle engine performance.
