Abstract

Poverty is not only seen from the inability in economic terms, but also the inability to fulfill education, health, and living standards. This study aims to determine the poverty status of households of smallholder oil palm harvest laborers in Air Rami Subdistrict, Mukomuko District, as well as the factors that influence multidimensional poverty. The research method used a quantitative approach with logistic regression analysis. The results showed that 30% of smallholder oil palm harvest laborer households were categorized as multidimensionally poor, with key indicators such as cooking fuel, years of schooling, and poor nutrition. Factors such as number of working days and health have a significant influence on multidimensional poverty, while variables such as land size, age, family dependents, alternative employment, and work experience are not significant. This study concludes that the multidimensional poverty of harvest labor households in Air Rami Sub-district is complex and multidimensional, not only related to income but also lack of access to basic needs.

Abstract

Lemon peel has various benefits and can be processed into higher-value products such as vinegar. Generally, vinegar is an acidic compound composed of acetic acid produced through a two-stage fermentation process. However, in this study, an innovation was introduced to convert acetic acid into lactic acid using Lactobacillus plantarum as the fermenting agent and sugar as the nutrient source. The aim of this study was to determine the effect of varying concentrations of L. plantarum and sugar on the chemical, physical, microbiological, and organoleptic characteristics of lemon peel vinegar. This study employed a Randomized Complete Block Design (RCBD) consisting of two factors: L. plantarum concentration (5%, 10%, 15%) and sugar concentration (15%, 10%, 5%). The results showed that the concentration ratio of L. plantarum and sugar significantly affected several characteristics of the lemon peel vinegar product. The best treatment was found in treatment A3, which used 15% L. plantarum and 5% sugar, with the following characteristics: moisture content of 93.43%, vitamin C content of 41.61 mg/100g, total titratable acidity (TTA) of 0.97%, pH of 2.76, viscosity of 3.72 cP, total plate count (TPC) of 13.75×10⁷ CFU/ml, and organoleptic test scores of 2.66 for color preference, 2.74 for aroma, 2.53 for taste, and 2.68 for texture.

Abstract

This study aims to examine sellers’ perceptions of foliage ornamental plants, identify consumer preferences, and compare the two perspectives. The research was conducted along a series of ornamental plant kiosks located on Sersan Bajuri Street, Cihideung Village, Parongpong District, Indonesia. The method used was a verificative survey. The seller population consisted of 362 individuals, from which 36 respondents were selected using simple random sampling, while 96 buyer respondents were selected using systematic random sampling. The findings indicate that sellers generally perceive ideal foliage ornamental plants as having green leaves, medium plant size, high durability, moderate popularity, small plant type, affordable price, a reasonably strategic sales location, and promotional activities primarily through social media. Conversely, buyers tend to prefer foliage ornamental plants with colorful leaves, medium size, high durability, moderate popularity, medium-sized types, affordable prices, strategic sales locations with diverse options, and social media-based promotions. Statistical analysis revealed significant differences between sellers’ perceptions and buyers’ preferences, particularly in terms of leaf color and plant type. However, an overall comparison using the Mann-Whitney U test yielded a Z-score of -1.207, with a critical Z-value of 1.96 and a significance level (2-tailed) of 0.227 (p > 0.05). These results suggest that, overall, there is no statistically significant difference between sellers’ perceptions and buyers’ preferences regarding the characteristics of foliage ornamental plants.

Abstract

Penggunaan plastik sebagai kemasan bahan pangan telah banyak digunakan dalam kehidupan sehari-hari. Akan tetapi plastik adalah pengemas yang kurang ramah lingkungan karena mempunyai karakter nonbiodegradable. Edible film menjadi alternatif untuk menggantikan plastik pengemas makanan karena bersifat biodegradable. Kulit singkong merupakan limbah agroindustri yang memiliki kandungan pati dan jahe merah memiliki senyawa antibakteri. Tujuan dari penelitian ini adalah untuk mengetahui karakteristik edible film berbasis pati kulit singkong dan pengaruh ekstrak jahe merah sebagai antibakteri terhadap edible film. Penelitian ini menggunakan desain Rancangan Acak Kelompok (RAK) non faktorial, yang melibatkan empat variasi konsentrasi pati kulit singkong (3%, 4%, 5%, dan 6%) sebagai perlakuan tunggal. Setiap perlakuan direplikasi sebanyak tiga kali untuk analisis statistik. Hasil penelitian meliputi ketebalan, kuat tarik, elongasi, mudah terurai, dan antibakteri pada perlakuan terbaik. Hasil penelitian menunjukkan bahwa konsentrasi pati kulit singkong berpengaruh nyata terhadap ketebalan, kuat tarik, dan mudah terurai akan tetapi berpengaruh tidak nyata terhadap elongasi. Konsentrasi pati kulit singkong P4 6% merupakan perlakuan terbaik.
