Abstract

Tepung pati aren merupakan hasil ekstraksi empulur pada batang aren. Proses pengeringan tepung pati aren bertujuan untuk memperpanjang umur simpan dan meningkatkan nilai harga jual tepung. Pengeringan tepung pati aren yang dilakukan saat ini masih menggunakan cara tradisional atau konvensional dengan menggunakan terpal sebagai lantai pengeringan. Proses pengeringan tersebut menyebabkan tepung pati aren tidak kering sempurna, membutuhkan waktu pengeringan yang lama serta berpotensi masuknya kontaminan seperti debu dan benda asing yang dapat merusak mutu tepung pati aren. Penelitian ini bertujuan untuk melakukan rancang bangun dan uji kinerja alat pengering efek rumah kaca (ERK). Alat pengering hasil rancangan diharapkan dapat mempercepat proses pengeringan serta meningkatkan mutu tepung pati aren. Metode penelitian yang digunakan adalah metode rancang bangun alat. Tahapan penelitian, diantaranya adalah identifikasi masalah, penetapan kriteria perancangan, perancangan alat pengering tipe ERK, perhitungan analisis teknik, pembuatan gambar teknik, pembuatan alat, uji kinerja alat serta pengolahan data. Alat pengering tepung pati aren tipe ERK yang telah dibuat memiliki panjang 4 m, lebar 2 m dan tinggi 1,5 m. Rangka alat pengering menggunakan konstruksi kayu dengan atap pengering berbentuk setengah oval menggunakan plastik UV 6%. Hasil dari pengujian alat didapatkan profil suhu rata-rata alat sebesar 37,2⁰C, RH rata-rata alat sebesar 41,85%, intensitas cahaya matahari rata-rata alat sebesar 301,16 W/m2, suhu bahan rata-rata alat sebesar 31.94⁰C, kadar air hasil pengeringan bahan rata-rata sebesar 15,46% (bb), laju pengeringan rata-rata sebesar 4,10% (bb)/jam, efisiensi alat sebesar 35,94%, serta efisiensi proses pengeringan sebesar 76,69%.

Abstract

This study discusses the scope of innovation diffusion in education in Indonesia. In essence, education plays a fairly essential role in shaping the quality of human resources that are able to face the challenges of the times. Along with global changes marked by technological developments and economic transformation, demands on the education system continue to increase. The researcher uses a Qualitative Literature Review which is carried out by the researcher reading and observing various written reference sources related to the scope of innovation in education in Indonesia. The results of this study indicate that overall, the process of innovation diffusion in education involves various complex stages and requires support from all parties involved in the education system. Diffusion of educational innovation in general can be concluded as a very complex process and is influenced by various specific factors, both internally and externally in the educational environment.

Abstract

The purpose of this study is to discuss the role of educational philosophy in the development of educational theory and practice in Indonesia. Education is an essential component of human life. Education is critical in shaping human character and traits. The author employs qualitative research techniques. The author employs a literature review as a research method, while perusing and observing multiple written sources of information associated to the topic of educational philosophy's role in the formation of the Independent Learning Curriculum in the development of educational theory and practice in Indonesia. According to the research findings, the Independent Learning Curriculum is a curriculum designed by the Ministry of Education, Culture, Research, and Technology to give educational institutions flexibility in establishing a curriculum based on their unique requirements and features. The autonomous Learning Curriculum embodies the ethos of autonomous learning, specifically the spirit of student-centered learning. This paper concludes that theme learning is one of the learning approaches used in the Merdeka Belajar curriculum. This is consistent with the progressive educational concept, which holds that education must be focused on students' needs and interests.

Abstract

Tempe is a nutritious food that is popular with many people. The problem is that tempe has a short shelf life and must be consumed immediately. Instant tempe is one of the innovative tempe products with a longer shelf life. This research aims to analyze the shelf life of instant tempe in various packages and at different storage temperatures using the Arrhenius model. The method used in this research was laboratory experimental, using 378 samples of instant tempe which were packaged in vacuum packaging, non-vacuum packaging, and cup packaging, and stored at cold temperature (12°C), room temperature (27°C), and hot temperature. (35°C). There are nine treatment combinations regarding the relationship between packaging and temperature, each treatment is carried out 3 times. Measurements for each treatment are carried out until the instant tempe cannot ferment to become tempe ready for consumption. This shows that the fungus Rhizopus oligosporus has died. The research results show that the CIE L* value of instant tempe decreases as the storage period for instant tempe increases. The shelf life of estimation results using the Arrhenius model for vacuum packaging and storage temperatures of 12°C, 27°C, and 35°C respectively is 36.98 days, 6.88 days, and 3.00 days. The use of non-vacuum packaging and storage temperatures of 12°C, 27°C, and 35°C were respectively 15.84 days, 5.63 days, and 2.38 days. In comparison, the use of cup packaging and storage temperatures of 12°C, 27 °C, and 35°C respectively are 17.62 days, 6.31 days, and 2.80 days.

Abstract

Fake palm oil seeds pose a substantial economic threat, which makes their authentication crucial. However, distinguishing between genuine and fake seeds remains a challenge. This study explored the potential of ultrasonic technology to measure shell thickness as a distinguishing factor based on the reported variations between the two types. Ultrasonic wave measurement software was developed using Arduino Uno to facilitate the analysis. The results highlight the complexity of accurately measuring the seed shell thickness owing to high attenuation. Micro-CT imaging confirmed the presence of pores within the seed structure, which significantly scattered and absorbed ultrasonic waves, limiting the penetration depth and accuracy. Despite these obstacles, the developed software exhibited promising capabilities, accurately determining the thickness or propagation speed with a high-resolution time-of-flight measurement of up to 62.5 nanoseconds. Additionally, the software is capable of sampling ultrasonic signals at frequencies up to 178 kHz. Although the software performs well under specific conditions, further advancements in ultrasonic technology are necessary to mitigate porosity-related limitations and enhance the effectiveness of seed authentication methods, particularly in transducer selection and measurement techniques such as Harmonic or QSC testing.
