Abstract

Mice are the main reservoir in transmitting leptospirosis, which is an infectious zoonotic disease caused by pathogenic leptospira bacteria, so it needs to be controlled effectively. Mice control has been using traps or rodenticides. One of the pesticides available is permethrin and malathion, which has been used as an insecticide. The purpose of this study was to determine the effectiveness of insecticide formulas as rodenticides in killing field mice, house mice, and tree mice. In the research of liquid rodenticide formula, the concentration is 0.025; 0.050 and 0.075% of the active ingredients were tested for efficacy against mice. Data analysis in the form of descriptive. The results showed that the absence of mice that died from these three types of mice, which showed a dose of 0.075%, was too small for mice so that they only experienced seizures. So that further testing is needed to make the killing power more effective on mice.

Abstract

Teh merupakan minuman yang dihasilkan dari pucuk daun tanaman Camellia sinensis  yang tumbuh di pegunungan pada ketinggian 600–2500 m dpl. Teh hitam merupakan jenis teh yang banyak dikonsumsi masyarakat Indonesia. Teh ini diproduksi dengan cara fermentasi melalui proses oksidasi enzimatis katekin oleh polifenol oksidase. Teh hitam yang dikemas dalam bentuk the celup banyak digemari konsumen.  Tujuan dari penelitian ini mengetahui konsentrasi polyfenol dalam teh hitam celup komersial. Sampel teh hitam celup komersial dengan merk dagang TP, TDT, TB, TL,  TD, dan TM diproduksi oleh enam perkebunan teh di Jawa Tengah yang diperoleh secara acak dari swalayan di Kota Semarang.   Kandungan polyfenol pada sampel teh hitam celup dianalisa dengan menggunakan spetrofotometer UV-Vis pada panjang gelombang 725nm. Hasil penelitian menunjukkan bahwa teh hitam celup komersial yang beredar di Kota Semarang telah memenuhi  standard SNI 3753–2014, dengan rata-rata konsentrasi polyfenol 8,83-43,63 %b/b. Analisa Zscore  menunjukkan tidak ada perbedaan yang sangat nyata antar konsentrasi polyfenol di enam sampel teh hitam celup komersial, hal ini dimungkinkan dengan adanya standarisasi proses produksi teh hitam di berbagai industri teh di Indonesia. Dan teh hitam celup komersial TDT mempunyai konsentrasi polyfenol diatas rata-rata yaitu 43,63 % b/b.    Tea is a drink produced from the leaves of the Camellia sinensis plant that thrives in the mountains at an altitude of 600–2500 m above sea level. Black tea is a type of tea that is widely consumed by Indonesian people. Black tea is produced by fermentation, namely the process of enzymatic oxidation of catechins by polyphenol oxidase. Black tea is produced in several packages, including as black tea bags. The purpose of this study was to determine the concentration of polyphenols in commercial black tea bags. Samples of commercial black tea bags with the trademarks TP, TDT, TB, TL, TD, and TM were produced by six tea plantations in Central Java which were obtained randomly from supermarkets/stores in Semarang City. The polyphenol content in black teabag samples was analyzed using a UV-Vis spectrophotometer at a wavelength of 725nm. The results showed that the commercial black tea bags marketed in the Semarang City had met the standards of SNI 3753–2014, with an average polyphenol concentration of 8.83-43.63% w/w. The Zscore analysis showed that there was no significant difference between the concentrations of polyphenols in the six samples of commercial black tea bags, this may cause by the standardization of black tea production processes in various tea industries in Indonesia, but commercial black tea bags with the trademark TDT had polyphenol concentrations above the average is 43.63% w/w.

Abstract

Kelareyan Village, Pemalang Regency is topographically a lowland area which is also the economic traffic of Pemalang district, so it is very suitable for agricultural and trading businesses. Kelareyan Village trading commodities are people's daily commodities such as food, beverages, clothing, medicine, and so on. With the position of the region, Kelareyan Village has enormous economic potential from the agricultural and trade sectors. The potential in question is the existence of a herbal beverage production center. In Kelareyan Village, there is a Kelareyan Independent Farmer Business Group (KUT) owned by Mr. Eko by producing instant ginger drinks from ginger-based ingredients. The problem faced by the Independent Farmer Business Group (KUT) is the contraction for ginger grinding with simple manual tools, causing the size of fine ginger to be not uniform so that it is less optimal in quality and quantity of production and other problems, namely the expired date printer that is still simple (stampel) so that it can still be quickly lost on the packaging. Therefore, the community service program that will be implemented focuses on socialization innovations and training on the use of ginger shredding machines and automatic expired date machines. In addition, the program was made with the aim that the Kelareyan Independent Farmer Business Group (KUT) can be more optimal in producinginstant ginger drinks.

Abstract

Mikroplastik merupakan partikel plastik yang berukuran 1–5000 μm. Mikroplastik dapat ditemukan dimana saja dan salah satunya adalah pada  air minum. Air minum dalam kemasan (AMDK) selama ini dianggap sebagai produk higienis sehingga aman dikonsumsi, dan menjadi andalan masyarakat untuk memenuhi asupan cairan tubuh. Penelitian ini bertujuan untuk menganalisis kandungan mikroplastik yang terdapat dalam AMDK yang beredar di Semarang, Jawa Tengah. Sampel berupa AMDK merek A dan P dalam kemasan botol plastik bervolume 600 dan 500 mL serta gallon bervolume 19 Liter diambil dari distributornya di Kota Semarang, yang dipanaskan dengan sinar matahari pada suhu 28 dan 40oC. Air sampel kemudian disaring menggunakan membrane filter PTFE hydrophilic dengan pori 0,22 µm dan dikeringkan dalam desikator selama 24 jam, ditimbang serta diamati dengan mikroskop stereo dan dengan FTIR Spectometer. Hasil penelitian menunjukkan bahwa di semua sampel terdapat mikroplastik dalam bentuk fragmen dan fiber yang berturut-turut berukuran 1,91-44,85µm dan 2,94-130,02 µm. Mikroplastik berukuran 1–10 µm mempunyai angka Z-score terbesar yaitu 1,953.  Jumlah dan berat mikroplastik tertinggi ditemukan pada air dalam kemasan botol P pada suhu 40oC yaitu 97 partikel/500 mL dan 0,0136 gr. Mikroplastik yang ada dalam AMDK merupakan plastic dengan gugus fungsi polyethylene terephthalate (PET), yang diperkirakan berasal dari kemasan AMDK tersebut.     Microplastics are plastic particles measuring 1–5000 μm. Microplastics can be found anywhere, and one of them is in drinking water. Bottled drinking water (or Air Minum dalam kemasan/AMDK) has long been considered hygienic. Hence, it is safe for consumption and has become a mainstay for people to fulfill their body's fluid intake. This research aims to analyze the microplastic content in AMDK marketed in Semarang, Central Java. Samples in the form of AMDK brands A and P in plastic bottles of 600 and 500 ml and gallons with a volume of 19 liters were taken from the distributor in Semarang City, which were heated with sunlight at temperatures of 28 and 40oC. The sample water was then filtered using a PTFE hydrophilic membrane filter with 0.22 µm pores, dried in a desiccator for 24 hours, weighed, and observed with a stereo microscope and an FTIR Spectrometer. The results showed that there were microplastics in all samples in fragments and fibers measuring 1.91-44.85µm and 2.94-130.02µm, respectively. Microplastics measuring 1–10µm have the largest Z-score, i.e. 1.953. The highest number and weight of microplastics were found in P bottles of water at a temperature f 40oC, i.e. ,97 particles/500 mL and 0.0136 gr. The microplastics in AMDK are plastics with the polyethylene terephthalate (PET) functional group, which is thought to come from their packaging

Abstract

Sikunang Village is one of 16 villages in Kejajar District, Wonosobo Regency, Central Java. Sikunang village with an area of 374 km2. Sikunang Village is referred to as an agropolitan village because of its abundant agricultural potential, especially carrots. Carrots that are ready to harvest are directly sold by farmers to middlemen so there has been no diversification of processed products from carrots that have a higher value. So it takes the creativity of citizens in diversifying processed food products from carrots. One of them is processing carrots into carrot jam using appropriate technology. The problem faced is that the jam cooker is still simple manual so that the doneness of the jam is not evenly distributed and some of the burnt is dark in color and the carrot jam filter has a small capacity so that it still cannot be perfectly smooth for the final result. Therefore, the community service program focuses on training innovations in the use of automatic jam cookers and jam filtration tools. In addition, the program was made with the aim that the Information and Counseling Center (PIK) for Adolescents in Sikunang Village and MSMEs in Sikunang Village can be optimal in producing carrot jam. It is expected that diversification of processed carrot jam food products will increase creativity in processing natural resources independently in the village and the economy of surrounding residents.
