Abstract

Five days after the Kelud Volcano eruption of 13 February 2014, lahar occurred in several channels of the Volcano. Rainfall with intensity of 26 mm/hour mobilized pyroclastic material from the upper slopes of Kelud Volcano down the channel during 3.5 hour. Using this eruption as a case study, the aims of this paper are (1) to study the geomorphic impact of lahars and (2) to study future hazards and risks due to the potential of lahar source material and lahar repose area. To reach these two goals, we use both primary and secondary data. The primary data comprises an integration of remote sensing, GIS approach, and fieldwork control, in order to investigate the geomorphic impacts of lahars. Secondary data were collected through interviews and statistical approach in villages, in order to determine their perception to the risk of lahar. Morphogenic processes such as riverbank erosion, channel-widening and riverbed downcutting took an important role in generating the impact of lahar in Kali Konto. The medial and distal areas were affected more largely affected than the proximal area. This major impacts have been river widening and buried crop field inside of the channel. This result allowed us to provide recommendation to population living along those areas at risk, in order to be prepared against the eventuality of potentially large and destructive lahars.

Abstract

Anemia pada ibu hamil merupakan masalah kesehatan serius yang dapat memengaruhi kesehatan ibu dan janin, dengan prevalensi mencapai 48,9% (Riskesdas 2018). Penelitian ini bertujuan untuk mengetahui hubungan antara kepatuhan konsumsi Tablet Tambah Darah (TTD) dan tingkat pengetahuan dengan kejadian anemia pada ibu hamil di RS Melania Bogor. Penelitian ini menggunakan desain cross-sectional dengan jumlah responden sebanyak 30 ibu hamil. Data dikumpulkan menggunakan kuesioner dan dianalisis dengan uji Chi-Square. Hasil penelitian menunjukkan terdapat hubungan signifikan antara tingkat pengetahuan (p-value = 0,000) dan kepatuhan konsumsi TTD (p-value = 0,001) dengan kejadian anemia. Responden dengan tingkat pengetahuan yang kurang dan kepatuhan rendah cenderung mengalami anemia, meskipun pemberian TTD sudah dilakukan. Berdasarkan hal tersebut dapat diketahui bahwa pentingnya meningkatkan edukasi tentang manfaat TTD serta mendorong kepatuhan konsumsi melalui pendekatan yang lebih intensif dan berkelanjutan.

Abstract

Synthesis of silica membrane from coal fly ash to decrease the color intensity of the liquid waste of sarung Samarinda industry has been done. The extraction of silica from coal fly ash by using the sol-gel process, and for silica membrane by using mixture of PVA (Poly Viny Acohol) and PEG (Polyethylen Glycol. Decrease in color intensity were analyzed using UV-Visible Spectrofotometer and the morphology of the membrane was observed by SEM-EDX. Based on the results from the spectrofotometer the concentration of the liquid waste berofe is 52.92 Unit Pt.Co and after decolorization is 25.04 Unit Pt.Co. The result show that decreasing are concentration is 52.68%, and the results the Scanning Electron Microscope (SEM)-EDX on the membrane after decolorization of liquid waste show distribution of pores in the membrane experiencing changes caused by new particles covering membrane be expected from liquid waste, and the elements are C, O, Na, Al and Si.

Abstract

Catfish has long been a popular fishery commodity among Indonesians (Santoso, S., Yanti, WS, & Manajemen, E. 2019). This research is an experimental study conducted in May 2024 at the nutrition laboratory of MH. Thamrin University and will be continued at the DKI Jakarta Regional Health Laboratory in September 2024. This study involved 25 undergraduate students of Nutrition at MH. Thamrin University, Jakarta, as panelists. This study used a Completely Randomized Design (CRD) with 3 different treatments and 2 replications. The data were processed using SPSS using the Analysis of Variance (ANOVA) test and will be continued to the Duncan's Multiple Range Test, if there is a significant difference in the ANOVA test. This study shows that the addition of kale and green beans affects the organoleptic quality of catfish nuggets, especially in the aspects of color, taste, and texture. However, there is no significant effect on aroma. The panelists' level of preference for color, taste, aroma, and texture also increased, although not significantly in the overall assessment. The best product was obtained in treatment P1 (10% kale and 20% mung beans). It is recommended that further research examine the product's shelf life, use fresh catfish without steaming, and apply an egg coating to prevent the breading from coming off easily.
