Abstract

Research on transesterification of soybean oil with sodium methoxide as the catalyst in methanol has been conducted. Yields of transesterification reaction were analyzed by gas chromatography-mass spectroscopy (GC-MS). GC-MS spectrum showed that mehtyl palmitic, methyl stearic, methyl oleic and methyl linoleic were produced from the reaction. The reaction was done for 90 minutes and gave convertion of 84.53% (b/b).

Abstract

Sintesis senyawa 4-(5-bromo-4-hidroksi-3-metoksifenil)-3-buten-2-ol dan uji potensi sebagai atraktan lalat buah telah dilakukan. Penelitian ini bertujuan untuk mensintesis senyawa 4-(5-bromo-4-hidroksi-3-metoksifenil)-3-buten-2-ol dan uji potensi sebagai atraktan lalat buah hama yang baru. Sintesis senyawa 4-(5-bromo-4-hidroksi-3-metoksifenil)-3-buten-2-ol tersebut dilakukan melalui tiga tahap, tahap pertama yaitu reaksi brominasi terhadap vanilin dengan menggunakan KBrO3 dan HBr dalam kondisi asam. Tahap kedua yaitu reaksi kondensasi aldol terhadap 5-bromovanilin dengan aseton menggunakan katalis NaOH 20%. Tahap ketiga yaitu sintesis senyawa 4-(5-bromo-4-hidroksi-3-metoksifenil)-3-buten-2-ol melalui reaksi reduksi produk kondensasi aldol dengan NaBH4. Senyawa produk hasil reaksi dianalisis dengan GC-MS dan FT-IR.  Hasil sintesis 4-(5-bromo-4-hidroksi-3-metoksifenil)-3-buten-2-ol berupa cairan dengan rendemen 48,77%. Uji potensi sebagai atraktan lalat buah hama menunjukkan bahwa senyawa hasil 4-(5-bromo-4-hidroksi-3-metoksifenil)-3-buten-2-ol dapat berpotensi sebagai atraktan lalat buah (Bactrocera spp).

Abstract

Abstract: The inadequate management of medical waste could have significant repercussions on the environment and public health. This study sought to assess the medical waste management procedures implemented in Yogyakarta's COVID-19 national referral hospitals during the pandemic. This study employed a descriptive research design with a qualitative approach. Data were gathered through interviews, observations, and the analysis of secondary sources. The findings were then juxtaposed with the regulations outlined in the Minister of Environment and Forestry's Regulation Number 56 of 2015 and the Guidelines for Waste Management in Referral Hospitals, Emergency Hospitals, and Health Centers Handling COVID-19 Patients. The research findings revealed that the referral hospitals had experienced a decline in medical waste sorting, storage, and transportation practices. Additionally, the incineration process employed an incinerator with the burner set at 1200°C, a procedure exclusively conducted by Hospital Y. The management of medical waste in these hospitals adhered to the relevant guidelines and regulations.Keywords: Medical Waste, Infectious Waste, Waste Management, COVID-19

Abstract

Fruit flies are an economic important of pest on horticultural crops. One of the commodities that are affected much due to fruit fly attack is salacca var. pondoh. The number of fruit flies attacking salacca increased from 2018 to 2021. The aims of the research was to study the population dynamics in salacca orchards in relation to climate factors and host plants. The research was conducted from July 2022 to May 2023 in salacca orchards that are members of the Salacca Farmers Association Mitra Turindo in Wonokerto, Turi, Sleman, Yogyakarta, Indonesia. The methods were counting the number of fruit flies trapped in three observation groups with different levels of sanitation and host plants around salacca orchards. Descriptive and arithmetic methods were used to determine the pattern of population oscillation among the three observation groups and differences in sanitation levels and host plants around the salacca orchards. The result showed that population fluctuations of Bactrocera spp. in salacca orchards were correlated with rainfall and relative humidity and less correlated with temperature and wind speed. Fruit fly abundance was lower in salacca orchards with better sanitation and fewer host plants around the salacca orchard.

Abstract

Fruit flies (Diptera: Tephritidae) are major pests in the horticultural sector. However, comprehensive information on their distribution across different habitats in Central Sulawesi is still lacking. This study aimed to assess the species diversity of fruit flies in three habitat types—urban, agricultural, and forest areas—in Central Sulawesi, Indonesia. Collections were conducted from November 2022 to May 2023 using Steiner traps baited with cue lure (CUE) and methyl eugenol (ME). Fruit fly specimens were identified to the species level, and diversity, dominance, and evenness indices were calculated. A total of 32 species and 10,393 individual fruit flies were collected across the three habitat types. The forest habitat exhibited the highest diversity and evenness indices, followed by agricultural and urban areas. In contrast, the urban habitat showed a higher dominance of certain species. The most dominant species were Bactrocera dorsalis (ME trap) and B. albistrigata (CUE trap). Notably, the presence of rare species found exclusively in forest habitats contributed significantly to the higher species richness observed there.
