Sosialization of Chitosan as Natural Preservation for Palm Tree’s (Arenga pinnata Merr.) Sap in Akelamo, Central Oba

Palm tree’s (Arenga pinnata Merr.) sap is the main ingredient for palm sugar. Palm tree’s sap is obtained by tapping the male flowers of palm tree. The sap is rich in sugar thus it is easy to be fermented. Palm farmers in Akelamo Village use soap as a preservation agent to prevent fermentation during the taping and loading period before the sap is cooked. Soap is a non-food product which is unsafe to be used in food product. Based on this fact, the community service program was designed to educate and share information about the danger of non-food preservation agent in food product, and also introduce chitosan as potential natural preservation to prevent fermentation process on palm tree’s sap among the palm farmers in Akelamo Village. There were four activities that had been done, such as discourse about food preservation and chitosan as natural preservation agent, workshop about how to apply chitosan to prevent fermentation during palm tree tapping, workshop about how to make palm sugar, and interactive dialogue with palm farmers. All the activities were done succesfully. The farmers were actively participated in every activity during the program

Mini Review: Hypocholesterolemic Potential of Unsaponifiable Matter from Palm Fatty Acid Distillate

Palm fruit as raw material of palm oil is the main commodity of Indonesian agriculture. Palm fatty acid distillate (PFAD) is a by-product of palm oil refinery process in deodorization stage. PFAD contained bioactive compounds such as vitamin E, phytosterols, and squalene. Vitamin E, phytosterols, and squalene have knows for its hypocholesterolemic effect and cardio protector. Bioactive compounds of PFAD can be separated from its fatty acid using saponification reaction. Saponification of PFAD produced unsaponifiable matter (USM) which was rich in bioactive compounds. Food fortification is aimed to enhance the nutrition quality of food for specific reason. The fortificant can be macronutrient or micronutrient. USM of PFAD potentially become food product fortificant which will give hypocholesterolemic effect. This review is discussed about hypocholesterolemic effect of each bioactive compounds in USM of PFAD and the potential of USM as food fortificant espsecially for food with hypocholesterolemic effect

User Interface and User Experience Analysis of Kejar Mimpi Mobile Application Using The User-Centered Design Method

User criticism on the Play Store revealed some flaws in the Kejar Mimpi App review. Observations were made on research that discussed the Kejar Mimpi Application, and it discovered that no prior research on User Experience and User Interface had been conducted. Interviews will be conducted to collect additional data, and the initial questionnaire will be distributed on May 6, 2022. Developers and designers use User-Centered Design (UCD) design methodologies to ensure that the product or system meets the users' needs. This study used the System Usability Scale (SUS) and User Experience Questionnaire (UEQ) methods or techniques to assess user interface and user experience. This research has produced as many as 24 design recommendations and a style guide. The final evaluation results measured using the SUS questionnaire increased the average value by 14,9% from a value of 67 (adjective rating Ok category, grade scale D, High Marginal category) to 77 (adjective rating Good, grade scale C, Acceptable category). The results of the UEQ also have gained an average increase in the ratio, where previously most were in below-average positions, now in good positions. Research on the user interfaces analysis and user experience of the Kejar Mimpi Application has the potential to be developed further. Therefore, the author has several suggestions that can be used for further research so that prototype part can be developed again to be more responsive and use different methods for evaluation of design results, such as Eye Tracking, Cognitive Walkthrough, and Heuristic Evaluation.User criticism on the Play Store revealed some flaws in the Kejar Mimpi App review.

Analisis pertumbuhan alga merah (Ptilophora pinnatifida) yang di budidaya pada skala laboratorium

Ptilophora pinnatifida termasuk dalam genus alga merah yang tersebar di Indo-Pasifik Barat, terutama dihabitat subtidal pada kedalaman lebih dari 100 meter. Genus ini jarang ditemui, 3 dari 14 spesies yang telah dikenali hanya dapat dikumpulkan dari arus atau aliran air. Spesies Ptilophora umumnya berasal dari perairan beriklim sedang (hanya 2 spesies yang diketahui berasal dari perairan beriklim tropis) dan secara biogeografis area penyebarannya masih terbatas. Laju pertumbuhan rumput laut umumnya mengalami peningkatan pesat pada periode tertentu tergantung pada umur tanaman tersebut dan setelah mencapai puncak, laju pertumbuhan akan menurun. Tujuan dari penelitian ini adalah untuk mengetahui pertumbuhan harian dan pertumbuhan spefifik alga merah (Ptilophora pinnatifida).
