Abstract

AbstractPandan wangi leaves have bioactive properties that can inhibit the growth of Staphylococcus aureus and Escherichia coli bacteria so they can prevent skin infections. The ability of pandan wangi leaf extract to inhibit microbial growth can be applied to liquid soap. This research was conducted to determine the characteristics of liquid soap with the addition of pandan wangi leaf extract. This study used a completely randomized design with five treatments and three replications. The treatment in this study was a variation of adding pandan wangi leaf extract to the liquid. soap formulation, which were 1.5; 2.0; 2.5; 3.0; and 3.5 grams. The data obtained was analyzed statistically using analysis of variance (ANOVA). The results of variance showed that the addition of pandan wangi leaf extract had a significant effect on foam stability, acidity (pH), anti-bacterial activity test, and sensory test. The liquid soap treatment chosen in this study was the addition of 3.5 grams of pandan wangi extract with a foam stability value of 81.52%, specific gravity of 1.0596 g/ml, viscosity of 271.7 mPas, acidity of 9.02, amount of free alkali 0%, has an anti-bacterial inhibition zone against Escherichia coli 11.22 mm and Escherichia coli 12.22 mm, does not irritate, and is preferred by hedonic panelists with a description of pandan wangi aroma.Keywords: anti-bacterial, liquid bath soap, pandan wangi leaf extract AbstrakDaun pandan memiliki sifat bioaktif yang dapat menghambat pertumbuhan bakteri Staphylococcus aureus dan Escherichia coli sehingga dapat mencegah infeksi kulit.

Abstract

AbstractRobusta coffee contains relatively high levels of caffeine, so consumption should be limited due to potential health risks if consumed excessively. This condition drives the development of effective, safe, and sustainable decaffeination technologies. Enzymatic decaffeination using a crude bromelain extract from pineapple peel offers a green chemistry approach that uses natural biocatalysts and agricultural waste. This study aimed to determine the optimal concentration of crude bromelain extract to reduce caffeine content in Robusta coffee beans and to evaluate its effects on moisture content, ash content, pH, and color brightness. A completely randomized design with one factor and six bromelain concentrations (0–50%) with three replications was applied. Data were analyzed using analysis of variance followed by Duncan’s multiple range test at a significance level of 0.05. The results showed that increasing bromelain concentration consistently reduced caffeine content from 2.74% to approximately 0.21% at 5% concentration. The pH and color brightness decreased as the enzyme concentration increased. The moisture content increased but remained below the national quality standard, whereas the ash content decreased, indicating mineral leaching during the enzymatic process. A crude bromelain concentration of 50% was considered practically optimal, achieving significant caffeine reduction with manageable physicochemical changes. These findings highlight the potential of scalable, efficient green decaffeination to support a sustainable, low-caffeine Robusta coffee industry.Keywords: bromelain, enzymatic decaffeination, green chemistry, Robusta coffee, pineapple peel AbstrakKopi Robusta memiliki kadar kafein relatif tinggi sehingga konsumsinya perlu dibatasi karena berisiko menimbulkan gangguan kesehatan jika dikonsumsi berlebihan. Hal ini mendorong pengembangan teknologi dekafeinasi yang efektif, aman, dan berkelanjutan. Dekafeinasi enzimatik menggunakan ekstrak kasar bromelain dari kulit nanas berpotensi menjadi pendekatan green chemistry melalui pemanfaatan biokatalis alami dan limbah pertanian. Penelitian ini bertujuan menentukan konsentrasi optimal ekstrak kasar bromelain untuk menurunkan kadar kafein biji kopi Robusta serta mengevaluasi pengaruhnya terhadap kadar air, kadar abu, pH, dan tingkat kecerahan warna. Percobaan disusun menggunakan rancangan acak lengkap satu faktor dengan enam taraf konsentrasi bromelain (0–50%) dan tiga ulangan. Data dianalisis menggunakan analisis ragam dan uji lanjut Duncan multiple range test pada taraf signifikansi 0,05. Hasil menunjukkan peningkatan konsentrasi bromelain menurunkan kadar kafein secara konsisten dari 2,74% hingga sekitar 0,21% pada konsentrasi 5%. Nilai pH dan kecerahan warna menurun seiring peningkatan konsentrasi enzim. Kadar air meningkat namun tetap di bawah standar mutu nasional, sedangkan kadar abu menurun yang mengindikasikan pelindian mineral selama proses enzimatik. Konsentrasi ekstrak kasar bromelain 50% dinilai paling optimal secara praktis karena menghasilkan reduksi kafein signifikan dengan perubahan mutu fisikokimia yang masih dapat dikelola. Temuan ini menunjukkan potensi penerapan dekafeinasi hijau yang efisien siap ditingkatkan skalanya dan mendukung keberlanjutan industri kopi Robusta rendah kafein.Kata kunci: bromelain, dekafeinasi enzimatik, green chemistry, kopi Robusta, kulit nanas

Abstract

Sago stem bark and coconut shell contain lignin and cellulose compounds which are quite high and have not been utilized optimally. Therefore this study aimed to obtain the best formulation of the sago stem bark and coconut shell as the main ingredients in making good quality briquette. The research was carried out experimentally using the Completely Randomized Design (CDR) method with 5 treatments and 3 replications. The treatments in this study were P1 (ratio of sago bark charcoal and coconut shell charcoal 90:10), P2 (ratio of sago bark charcoal and coconut shell charcoal 80:20), P3 (ratio of sago bark charcoal and coconut shell charcoal 70:30), P4 (ratio of sago bark charcoal and coconut shell charcoal 60:40), P5 (ratio of sago bark charcoal and coconut shell charcoal 50:50). Data obtained were statically analyzed by analysis of variance (ANOVA) and continued with Duncan’s New Multiple Range Test (DMRT) at level 5%. The results show that the ratio of sago stem bark and coconut shells did not significantly affect moisture, ash and bound carbon contents as well as density, heating value, volatile matter levels and fuel power. The best treatment was P5 (rasio of sago bark charcoal and coconut shell charcoal 50:50) with moisture content 3.67%, ash power 4.54%, volatile matter 1.13%, density power 0.67 g/cm3, bound carbon 90,68%, calorific value 7748.62 cal/g and fuel power 0,0029 g/second.

Abstract

Village Talang Maur is known as an agroindustry producing palm sugar. The agroindustry is experiencing problems in marketing palm sugar which will affect the agroindustry income and has not been able to determine efficient marketing channels. The objective of this study was to examine which marketing channels are the most effective in the palm brown sugar agroindustry. Marketing of palm brown sugar agroindustry consists of two marketing channels, namely channel I includes farmers (producers) – retailers – consumers, channel II includes farmers (producers) – collectors – retailers – consumers. Marketing channel I is an efficient channel consisting of a marketing margin of IDR 4000, 15,6% percentage margin, 84,3% farmer’s share, and 5,27% marketing efficiency while marketing channel II is is an efficient channel consisting of a marketing margin of IDR 8000, 30,5% percentage margin, 71,4% farmer’s share, and 10,01% marketing efficiency Channel I is considered the most efficient due to its low marketing efficiency, high farmer’s share, and lowmarketing margins.
