Abstract

The purpose of pasteurization of milk is to improve the quality of the milk, kill pathogenic and non-pathogenic bacteria. The heating process is carried out to eliminate pathogenic microorganisms in milk, but pathogenic microorganisms can grow again after processing and packaging milk. Based on this, it is necessary to test the safety level of pasteurized milk. An important test that needs to be carried out is the physicochemical properties. The results of testing pasteurized milk using a cold chain showed a pH of 6.7, protein content about 2.67%, and fat content about 3.37%.  The influence of pasteurized milk storage conditions on its physicochemical properties also needs to be tested. The test results showed that the acidity of pasteurized milk increased during two days of storage at 20°C from 0.142 ± 0.00119% to 0.162 ± 0.00342%, the pH was lowered by 0.068 units, the average electrical conductivity (EC) increased from 5.220±0.0397 mS/cm to 5.880±0.1006 mS/cm. Increasing temperature and storage time causes an increase in phosphate ions and lowers pH rapidly, because acidification of milk causes changes in salt balance. Physical and sensory quality tests of pasteurized milk products were also carried out to determine the effect of temperature and transportation time. The test results explained that at 72 hours of transportation with a temperature of 5oC the pH value was 6.7-6.8.  These results indicate that the pH of pasteurized milk still complies with SNI, this condition is also supported by the sensory condition which is still normal.

Abstract

Penelitian pembuatan pupuk kompos dari Tandan Kosong Kelapa Sawit (TKKS) dan decanter solid telah dilakukan di Pusat Pengolahan Sampah Terpadu (PPST) di Universitas Andalas dengan tujuan untuk mendapatkan perbandingan komposisi terbaik pupuk kompos dengan memanfaatkan limbah TKKS dan decanter solid. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 3 ulangan. Perlakuan pada penelitian ini adalah perbedaan berat TKKS dan decanter solid, dengan masing-masing perlakuan A = TKKS 3 kg dan decanter solid 0 kg, B = TKKS 2,5 kg dan decanter solid 0,5 kg, C = TKKS 2 kg dan decanter solid 1 kg, D = TKKS 1,5 kg dan decanter solid 1,5 kg, E =  TKKS 1 kg dan decanter solid 2 kg. Hasil penelitian ini menunjukkan pengolahan pupuk kompos dari TKKS dan decanter solid memberikan pengaruh berbeda tidak nyata terhadap kadar air 49,5% dan pH 7,10%, dan sedangkan hasil pengujian unsur hara pupuk kompos berupa nitrogen 1,56 %, phosfor 0,73%, kalium 0,55%, C-Organik 24,36%, C/N ratio 15,6% telah memenuhi standar SNI 19-7030-2004. Berdasarkan analisis yang telah dilakukan dipilih perlakuan terbaik yang sesuai dengan standar SNI 19-7030-2004 yaitu perlakuan C (TKKS 2 kg dan decanter solid 1 kg).

Abstract

This study aimed to evaluate the effect of green tea extract addition on the stability of Caesalpinia sappan (sappanwood) extract under ultraviolet (UV) radiation exposure. A completely randomized factorial design was employed using two factors: the combination ratio of sappanwood and green tea extract (100%:0%, 85%:15%, and 70%:30%) and the duration of UV exposure (0, 30, and 60 minutes). Parameters analysed included colour, antioxidant activity (IC??), total anthocyanin content, and spectrophotometric absorbance. The results demonstrated that both factors significantly affected the stability of the extract. The addition of green tea extract, particularly at a ratio of 85% sappanwood to 15% green tea, yielded the highest antioxidant activity (6.77 ?g/mL) and anthocyanin total (4.98%), indicating enhanced stability due to the antioxidant and photoprotective effects of catechins. However, the longer the exposure time, the lower the antioxidant activity and total anthocyanin. These findings emphasize the possible use of green tea as a natural copigment to enhance the photostability of brazilin-containing herbal extracts, thereby broadening their functional and pharmaceutical applications.

Abstract

Limau Manis Village as Kampung Manggis is supported by the production of mangosteen in Padang City which is number 2 (two) in West Sumatra and 80% of mangosteen in Padang City comes from Pauh Subdistrict, with the center being in Limau Manis Village and the existence of Kampung Manggis brings hope for the community to improve their economy and will have an impact on the economy of the Padang City community. The skin of mangosteen fruit can be processed into value-added products. However, farmers and local businesses still face several challenges, such as the lack of knowledge and technology to process mangosteen peels into economically valuable products. Abundant mangosteen peels during the harvest season are often discarded or burned, causing environmental impacts such as soil and air pollution. However, due to the lack of public knowledge on mangosteen peel processing as waste, an innovative solution is needed to turn mangosteen peel waste into a new source of income through the development of competitive derivative products. This community service activity is designed as a strategic step to empower the community, optimize local potential, and build an innovative, sustainable mangosteen agroindustry, creating value-added products and improving the economic welfare of the community. In addition, this activity is also expected to be a model of agroindustry development based on local potential that can be developed. The purpose of this community service activity is to provide training in improving the knowledge, skills of the community in processing mangosteen skin, increasing the added value of mangosteen skin into mangosteen skin tea and mangosteen skin syrup products that have a broad impact on economic, social and environmental improvement.
