Abstract

The study of the Effect of Cesium-137 Gamma Ray Radiation on the Growth of Soybean Plants (Glycine max L.) aims to determine the quality of growth of soybean plants (Glycine max L.). The Cesium-137 source was used as a source of irradiation in the study, with a constant distance (x) of irradiation of 100 cm from the wall, with dose variations of 0 Control, 25 mGy, 50 mGy, 75 mGy, 100 mGy and 120 mGy. The method used in this research is descriptive statistical analysis. The samples used in this research are soybean seeds from the Langkowa Soybean plantation, Tonasa Village, Tombolopao Subdistrict and packaged soybeans taken from the packaging seeds of Flower Seed Shop Jl. Veteran Selatan No.395. The results of this study showed that the sprout growth time with a dose treatment of B5 (75 mGy) took 9 days to grow, the percentage of stem height (cm) at a dose of B5 (75 mGy) the average stem height was 3.7 cm, the percentage of leaf width (cm) at a dose of B4 (100 mGy) the average leaf width was 2.9 cm, the percentage of the number of leaves (sheets) at a dose of B3 (75 mGy) the average number of leaves was 4 sheets. The use of Cesium-137 and Cobalt-60 Gamma radiation in plant breeding can be utilised on various types of plants to increase plant cultivation and better production results.

Abstract

This study investigates the effects of gamma radiation from Cesium-137 on the growth of bean plants (Phaseolus vulgaris L.) to understand its impact on plant quality. The Cesium-137 source was applied at a constant distance of 200 cm from the wall, using dose variations of 0 (control), 25 mGy, 50 mGy, 75 mGy, 100 mGy, and 125 mGy. The seeds used in this research were sourced from the Arango bean plantation in Arabika Village, Sinjai Barat District. A descriptive statistical analysis method was employed, presenting the data in tables that were then converted into graphs to illustrate the germination time (in days), stem height (cm), leaf width (cm), and leaf count (number of leaves). The results revealed that sample D, exposed to a radiation dose of 75 mGy, took only 5 days to germinate, with an average stem height of 45 cm, leaf width of 10.6 cm, leaf count of 16 leaves, and an average fruit mass of 0.008 kg. In contrast, the normal germination time for bean plants is 7 days, with a stem height of approximately 30 cm, leaf width of 6 cm, leaf count of 14 leaves, and a fruit mass of 0.006 kg. However, it was observed that both excessively low and high radiation doses could hinder the growth of bean plants.

Abstract

Penelitian mengenai bio-briket berbahan dasar limbah kulit kakao, kulit pisang Musa Paradisiaca L., dan tepung tapioka dilakukan sebagai solusi bahan bakar alternatif pengganti bahan bakar fosil. Pada penelitian ini dibuat beberapa briket dengan variasi campuran yang bertujuan untuk mengetahui karakteristik dan perbandingan komposisi campuran kulit kakao, kulit pisang Musa Paradisiaca L., dan tepung tapioka sehingga diperoleh briket bioarang yang memenuhi standar Standar Nasional Indonesia (SNI) berdasarkan kualitas seperti kadar air, kadar abu, nilai kalor, kerapatan, dan lama pembakaran. Metode pembriketan yang digunakan adalah teknik pemadatan dengan menggunakan bahan baku padat. Bahan baku yang digunakan untuk pembuatan briket adalah kulit kakao kering, kulit pisang Musa Paradisiaca L., dan tepung tapioka yang digiling halus dengan cara digiling. Perbandingan sampel kulit kakao, kulit pisang Musa Paradisiaca L., dan tepung tapioka yang digunakan dalam penelitian ini adalah 70:20:10 (sampel A), 75:15:10 (sampel B), dan 80:10:10 (sampel C). Berdasarkan hasil penelitian dari ketiga variasi sampel tersebut, sampel B menunjukkan nilai yang paling optimal dibandingkan dengan sampel lainnya. Sampel B menunjukkan nilai kalor sebesar 2.814 kkal/g, massa jenis 0,55 g/cm³, kadar abu 14%, kadar air 8%, dan lama pembakaran 13 menit. Beberapa parameter yang diuji telah memenuhi standar SNI, khususnya kadar air dan kerapatan briket. Namun demikian, briket bioarang ini dinilai layak untuk digunakan sebagai bahan bakar alternatif.

Abstract

Edible film berbasis pati menawarkan alternatif kemasan biodegradable, tetapi masih memiliki keterbatasan pada kekuatan mekanik dan sensitivitas terhadap air. Penelitian ini bertujuan menyintesis dan mengevaluasi edible film biokomposit dari pati jagung, gliserol, dan serbuk limbah kulit salak sebagai penguat lignoselulosik melalui metode solvent casting. Formulasi menggunakan 6 g pati jagung, 4 mL gliserol, serta variasi serbuk kulit salak 0,5 g (A), 0,7 g (B), dan 0,9 g (C). Karakterisasi mencakup kuat tarik, elongasi, modulus elastisitas, penyerapan air, biodegradasi, dan spektroskopi FTIR. Kuat tarik meningkat dari 0,271 MPa pada A menjadi 0,752 MPa pada B dan 1,008 MPa pada C. Modulus elastisitas juga meningkat dari 4,46 menjadi 7,10 MPa. Elongasi tertinggi diperoleh pada B sebesar 15,27%, sedangkan C menurun menjadi 14,21%, yang menunjukkan bahwa penambahan penguat pada konsentrasi lebih tinggi meningkatkan kekakuan film. Penyerapan air terendah diperoleh pada A sebesar 4,65%, sedangkan B dan C masing-masing sebesar 27,56% dan 23,43%. Pada hari ke-5, biodegradasi mencapai 28,05% (A), 35,66% (B), dan 100% (C); seluruh formulasi terdegradasi 100% pada hari ke-7. Spektrum FTIR menunjukkan pita O–H, C–H, C=C/H–O–H, C–O, dan daerah sidik jari polisakarida yang mengonfirmasi interaksi fisik antarkomponen. Formulasi B memberikan keseimbangan mekanik terbaik, sedangkan A unggul dalam ketahanan air dan C dalam kekuatan serta laju biodegradasi. Hasil ini menunjukkan adanya trade-off kuantitatif antar sifat dan memperkuat potensi serbuk limbah kulit salak sebagai penguat edible film berbasis pati jagung.
