Abstract

The aim of this work is to study theoretically, by mathematical model development, the effect of particle size distribution on the performance of rotary dryer to dry ammonium sulphate fertilizer assuming plug flow with axial dispersion pattern (PFDA model) for solid particle flow. The mathematical model development was carried out by combining the drying processes model with particle size distribution model. Particle size distribution models used are Rosin-Rommler model and Gamma distribution model. For simplicity, the model of drying processes of solid particles in the rotary dryer was developed by assuming of uniform air conditions (temperature and humidity) along the rotary dryer as in the entry conditions. The resulting differential equations were solved analytically under Matlab 6.1 facility.Since this model, solid hold up, and axial dispersion number were obtained from empirical correlations in the literatures. The drying rate of ammonium sulphate fertilizer in rotary dryer was estimated using isothermal diffusion model with effective diffusivity of moisture in the particle obtained from previous study [2]. Using Gamma function distribution, this research showed that for the value of the coefficient of variance (CV) less than 0.5, particle size distribution does not have significant effect on dryer performance. For the value of CV greater than 0.5, the dryer performance increase (or outlet solid moisture content decrease) with increasing the value of CV. The application of Rosin-Rammler model gives lower prediction of outlet solid moisture content compared to the application of Gamma function model.

Abstract

Shallot is an important spice and seasoning in Indonesia. It is consumed almost daily in many dishes. The objective of this experiment was to study the effect of the medium and the variety on the yield of shallots grown in a polybag. The experiments were arranged in a two-factorial randomized complete block design with three replications. The factors were medium (1 soil: 1 paddy husk ash and 1 soil: 1 compost) and variety (Agrihorti 1 and Mentes). Data were statistically analyzed by Analysis of Variance (ANOVA), and the means were compared using Honestly Significant Difference (HSD) at P < 0.05. There was no interaction between medium and variety. Overall, all treatments did not significantly affect yield. Varieties were significant differences on bulb diameter; however, they were not significant differences on bulb height, fresh bulb weight per polybag, and bulb number per polybag. Those media are considered as precise media due to they contain organic materials.

Abstract

Wastewater from the food industry that contains a high organic load, such as wastewater from the tofu manufacturing process, requires an appropriate and efficient treatment system to reduce pollutants before being discharged into water bodies. The most suitable treatment for high organic loads is the anaerobic treatment system. The anaerobic treatment process is a system of suspended media, attached media, or the combination thereof as a hybrid. This study uses a Hybrid Upflow Anaerobic Sludge Blanket (HUASB) reactor with the consideration that this reactor has advantages in maintaining high concentrations of biomass, high operating load rates, good decomposition capabilities, and good solid-liquid separation due to suitable granulation. The purpose of this study was to determine the effect of the addition of the trace metal FeCl3 on biogas production and the ability to remove pollutants in the tofu industrial process wastewater treatment in the HUASB reactor. The operation of the reactor uses variations in the concentration of tofu industrial waste water (75 and 100%) and trace metal concentrations (0.3–0.6 mg/L). The optimum biogas production was obtained with 8190 mL at a concentration of 75% tofu industrial waste water, a trace metal concentration of 0.6 mg/L FeCl3, and removal of COD and TSS of 94.09% and 94.2%, respectively. The role of the trace metal FeCl3in the anaerobic process shows that it is a source of nutrition for increasing the growth of microorganisms in anaerobic systems so that biogas production and pollutant removal are increased.

Abstract

The general election (Pemilu) is a process by which people elect individuals to political positions at various levels in Indonesia. Elections are conducted to elect leaders such as presidents or executive officials, representatives of the people in the legislature, and village heads. A quality election will certainly give birth to quality leaders as well. The Village Head as a leader at the village level will represent the quality of a village. Thus, the function of the Village Head towards village development is to think, plan, and implement. One of the efforts made by the Cianjur Regency Government to improve the quality of the implementation of the simultaneous village elections is by creating an E-Administration system to be used in the registration process for candidates for village heads. The purpose of creating this E-Administration system is to facilitate the organizers and prospective village head candidates in the implementation of registration The implementation method in this service activity goes through several preparatory stages, namely First, increasing commitment. Second, development and harmonization of the e-administration system prototype. Third, supervision of the legalization process. And fourth, mentoring/technology transfer of the e-administration system. The results of this research are the formation of an E-Administration system designed by the IT Team of the Faculty of Engineering, Suryakancana University, which is adaptive to existing systems in stakeholders or institutions.

Abstract

Varietas semangka hibrida memiliki produktivitas dan keseragaman yang tinggi sehingga diminati oleh konsumen. Penelitian ini bertujuan untuk mengevaluasi beberapa hibrida hasil persilangan antara galur inbrida dengan varietas Serif Saga Agrihorti (SSA) sebagai tetua jantan. Percobaan menggunakan rancangan acak kelompok (RAK) dengan tiga ulangan, melibatkan 12 hibrida hasil topcross dan Serif Saga Agrihorti (SSA) sebagai satu varietas pembanding. Semua genotipe ditanam di lapangan dengan mengikuti praktik agronomi semangka yang standar. Karakteristik yang diamati meliputi waktu berbunga jantan dan betina, umur panen, serta diameter dan bobot buah, ketebalan kulit buah, tingkat kemanisan, dan jumlah biji fertil dan biji steril. Data dianalisis menggunakan ANOVA dilanjutkan dengan uji BNT (Beda Nyata Terkecil). Variabilitas genotipik dan fenotipik, heritabilitas dan koefisien korelasi genotipik dan fenotipik  karakter, diestimasi berdasarkan partisi nilai ragam dari ANOVA. Hasil penelitian menunjukkan variabilitas genetik yang luas pada karakter umur berbunga jantan dan betina, serta bobot buah. Nilai duga heritabilitas yang tinggi diperoleh pada karakter umur berbunga jantan dan betina, bobot buah, diameter buah dan jumlah biji fertil. Empat genotipe hibrida yaitu G1, G6, G8, dan G10, menunjukkan bobot buah dan tingkat kemanisan yang lebih tinggi dibandingkan varietas SSA. Berdasarkan heritabilitas yang tinggi pada karakter bobot buah, maka keempat hibrida ini berpotensi untuk dikembangkan menjadi varietas semangka hibrida baru atau dimanfaatkan sebagai populasi dasar untuk perakitan varietas bersari bebas.

Abstract

This study aims to develop and examine the effectiveness of a Culturally Responsive Teaching (CRT)-based module to enhance narrative text reading comprehension among grade 4 elementary students. CRT was selected for its strength in integrating the local cultural context of West Java into the learning process, creating a cognitive bridge between students' daily experiences and the material. The research employed a modified 4D R&D model that included cultural analysis. Participants involved material, language, and media experts, teachers, and 30 fourth-grade students from SDN Puncakmanis, Sukabumi Regency. Data were collected using expert validation, questionnaires, and reading comprehension tests. Results indicated that the CRT-based module was valid (material 87.27%, language 88.33%, media 85%), practical (teachers 93.33%, students 87.22%), and effective—evidenced by an N-Gain of 0.61 (medium category) and an improvement in learning completeness from 40% to 100%. The findings suggest that CRT-based learning can significantly improve students' reading skills and support the integration of cultural relevance in education. However, the study's limitation lies in its specific cultural scope (West Java), suggesting a need for adaptation in other regions with different cultural backgrounds. Additionally, implementation was limited to a single school, requiring broader application for generalization. Highlights: Culturally Relevant: Integrates West Java culture to boost reading comprehension. Well-Validated: Scored highly in expert and user evaluations. Effective Results: Improved learning completeness from 40% to 100%. Keywords: Teaching Module, Culturally Responsive Teaching, Reading Comprehension Skills, Narrative Text, Elementary School
