Abstract

Heat-moisture treatment (HMT) is known as one of physical modification techniques that improves the functional property of starch. Taro beneng starch isolated from taro beneng tuber was modified by HMT to improve its application in the food product. The aim of this research is to determine the physical and functional properties of taro beneng starch modified by HMT. HMT were applied to the taro beneng starch using three different temperatures (90,100, and 100oC). This research was conducted using a randomized-complete design. The results showed that the temperature did not had a significant effect on the whiteness degree and lightness, however had a significant effect on the resistant starch content and flowability of the modified starch. Future studies about its effect on the nutritional and crystallinity characteristics of this starch need to be done to provide a better understanding of the implications of this technique.

Abstract

The quality of palm sugar is greatly influenced by the characteristics of the coconut sap raw material, especially the acidity level (pH), which plays an important role in the crystallization process. The purpose of this study is to analyze the chemical characteristics (reducing sugar content, moisture content, ash content), organoleptic characteristics and panelists' preference levels (color, aroma, taste), and to determine the optimal pH of coconut sap that produces the best palm sugar quality according to quality standards. The research method used was a Completely Randomized Design (CRD) with 4 treatments of sap acidity levels (pH), namely pH 5, pH 6, pH 7, and pH 8. Each treatment was repeated 3 times. The observed parameters included moisture content, ash content, reducing sugar content, as well as an organoleptic test of panelists' preference for the color, aroma, and taste of the resulting palm sugar. The obtained data were analyzed using Analysis of Variance (ANOVA), and if there were differences among treatments, they were further tested with a 5% LSD test. The study results showed that the resulting palm sugar had: reducing sugar content (3.21-6.17%), moisture content (2.27-3.85%), ash content (7.76-21.53%), and the preference test results for color (slightly like-very like), aroma (slightly like-very like), and taste (slightly like-like). It is concluded that the sap acidity level (pH) significantly affects the moisture and ash content of palm sugar, but does not significantly affect the reducing sugar content. The best brown sugar was obtained at pH 8 treatment, which resulted in a lighter color, smooth texture, low moisture content (2.27%), ash content (15.31%), and reducing sugar content (3.21%).

Abstract

Aglaonema 'Dud Unyamanee' merupakan tanaman hias populer yang menghadapi kendala perbanyakan konvensional yang lambat dan terbatas. Benzyladenine (BA) diketahui dapat merangsang tunas lateral dengan memecah dominasi apikal. Penelitian ini bertujuan menentukan konsentrasi BA terbaik untuk menginduksi tunas Aglaonema 'Dud Unyamanee' secara ex-vitro. Penelitian menggunakan Rancangan Acak Lengkap faktor tunggal dengan empat konsentrasi BA (0, 100, 200, dan 300 ppm). Larutan BA diaplikasikan dengan penyemprotan pada pangkal batang seminggu sekali selama empat minggu. Pengamatan dilakukan hingga 12 minggu setelah aplikasi , meliputi persentase kemunculan tunas, jumlah tunas, panjang tunas, diameter tunas, dan jumlah daun. Hasil penelitian menunjukkan aplikasi BA berpengaruh sangat nyata. Perlakuan BA 300 ppm (P3) menunjukkan hasil terbaik, mencapai 100% tunas muncul pada minggu ke-4 , dibandingkan kontrol (0 ppm) yang hanya 41,67% pada minggu ke-12. Konsentrasi 300 ppm juga menghasilkan jumlah tunas (6,83) , panjang tunas (12,93 cm) , diameter tunas (8,92 mm) , dan jumlah daun (13,58 helai) tertinggi. Disimpulkan bahwa aplikasi BA 300 ppm paling efektif untuk mempercepat inisiasi dan meningkatkan pertumbuhan tunas Aglaonema 'Dud Unyamanee'. ABSTRACT Aglaonema 'Dud Unyamanee' is a popular ornamental plant facing constraints from slow and limited conventional propagation methods. Benzyladenine (BA) is known to stimulate lateral shoot growth by breaking apical dominance. This study aimed to determine the most effective concentration of BA for inducing lateral shoots in Aglaonema 'Dud Unyamanee' via ex-vitro application. The research used a single-factor Completely Randomized Design (CRD) with four BA concentrations (0, 100, 200, and 300 ppm). The solution was applied by spraying the stem base once a week for four weeks. Observations were made up to 12 weeks after application , measuring shoot emergence percentage, shoot number, shoot length, shoot diameter, and leaf count. The results indicated that BA application had a significant effect. The 300 ppm BA treatment (P3) showed the best results, achieving 100% shoot emergence by week 4 , whereas the control (0 ppm) only reached 41.67% by week 12. The 300 ppm concentration also yielded the highest shoot count (6.83) , shoot length (12.93 cm) , shoot diameter (8.92 mm) , and leaf count (13.58). It is concluded that a 300 ppm BA application is most effective for accelerating initiation and enhancing the growth of Aglaonema 'Dud Unyamanee' lateral shoots.

Abstract

The Smallholder Palm Oil Rejuvenation Program (PSR) is a strategic government policy aimed at improving the productivity and sustainability of smallholder oil palm plantations, in which farmer institutions play a pivotal role in ensuring effective implementation. This study aims to analyze the factors influencing the role of independent smallholder farmer institutions in supporting the implementation of the PSR program in Indragiri Hilir Regency, Riau Province. A quantitative approach was applied through a survey of 200 independent oil palm farmers, and data were analyzed using Structural Equation Modeling – Partial Least Squares (SEM-PLS) with SmartPLS software. The results show that Institutional Managerial (β = 0.337; p < 0.001), Institutional Performance (β = 0.329; p < 0.001), and Technical and Productivity (β = 0.317; p < 0.001) have a positive and significant effect on the Institutional Role of smallholder farmers. The model demonstrates strong predictive capability, with an R² value of 0.748, indicating that these factors collectively explain a substantial proportion of the variance in institutional effectiveness. These findings highlight the importance of strengthening internal institutional capacity through sound governance, enhanced performance accountability, and improved technical competence to optimize the role of farmer institutions in supporting the success of the PSR program. The study recommends managerial training, institutional transparency, and technology transfer as key strategies to reinforce the strategic role of farmer institutions in achieving sustainable palm oil smallholder development.

Abstract

The use of local ameliorants has the potential to be an effective solution in improving the quality of post-tin mining soil that is poor in nutrients and has a coarse texture. This study aims to analyze the effect of oil palm bunch ash, coconut shell ash, and chicken manure on the germination of two kale varieties (Nemo and Nita) in degraded media. The study used a two-factor Completely Randomized Design (CRD) at the Precision Agriculture Laboratory of the Bangka Belitung State Manufacturing Polytechnic. The parameters observed included plumule length, radicle, fresh weight of seedlings, fresh weight of roots, and dry weight of roots. The results showed that the percentage and germination capacity did not differ significantly between treatments. However, radicle length, fresh weight, and dry weight of seedlings showed a significant effect, with the best response achieved by the coconut shell ash and oil palm bunch ash treatments. Local ameliorants also caused positive changes in soil physical properties, especially in the color and texture of the media. In conclusion, local ameliorants proved effective in improving the initial conditions of post-mining soil and successfully supported kale germination.
