Abstract

Putri Malu (Mimosa pudica L.) is a weed that often found in various places, especially on agricultural land and plantations. Mangifera indica L. has potential as a bioherbicide because it contains aleochemical compounds, which inhibit the growth of other plants. This research aims to determine the potential and the best concentration of methanol extract of mango leaves (Mangifera indica L.) in inhibiting the growth of putrimalu weed (Mimosa pudica L.). This research was carried out for four months, in the Kasa House Laboratory, Biology Department, Faculty of Mathematics and Natural Sciences, Tanjungpura University. The research used a Completely Randomized Design (CRD) with five mango leaf extract concentration treatment levels, namely control (P0), 10% (P1), 20% (P2), 30% (P3), and 40% (P4). Each treatment was repeated five times to obtain 25 experimental units. The results showed that the methanol extract of mango leaves (Mangifera indica L.) had an effect on inhibiting the germination and growth of the M. pudica weed. The best concentration of methanol extract of mango leaves in inhibiting the germination and growth of putrimalu weed is a concentration of 20%.

Abstract

Glutinous corn (Zea mays L. var. ceratina) is a local variety known for its distinctive traits, particularly its high amylopectin content, comprising 72% amylopectin and 28% amylose. This research aims to explore the impact of incorporating Naphthalene Acetic Acid (N.A.A.) and coconut water and identify the optimal concentrations that influence the growth of epicotyl shoots in glutinous corn. The study was conductedk in the Tissue Culture Laboratory at the Department of Biology, Faculty of Mathematics and Natural Sciences, Tanjungpura University in Pontianak. A completely randomized design (C.R.D) with factorial arrangements was employed. The first factor considered various concentrations of NAA (0, 0.5, 1.0, and 1.5 ppm), while the second factor involved coconut water at different concentrations (0%, 15%, 30%, and 60%). The findings indicated that the combination of NAA and coconut water significantly impacted the shoot emergence time and height. The combinations of 0.5 ppm NAA with 15% and 30% coconut water resulted in the fastest shoot growth, averaging 2.4 days after seed treatment (hst). In contrast, using 30% coconut water alone, without NAA, produced the tallest shoots, averaging 3.48 cm. However, the growth of glutinous corn epicotyl shoots was optimal only until 14 days of age.

Abstract

Sugarcane sap is a liquid found in sugarcane stalks, which can be drunk directly as a refreshment and as a basic ingredient for making granulated sugar. The nutritional content contained in sugarcane juice can be a growth medium for Acetobacter xylinum bacteria forming cellulose (nata). One of the factors supporting the growth of Acetobacter xylinum bacteria is a nitrogen source. This study aims to determine the effect and the best concentration of soybean extract on the quality characteristics of nata de cane. The research design used was a completely randomized design (CRD) with 7 concentrations of nitrogen sources including control (0%), 1% ZA, 2.5%, 5%, 7.5%, 10% and 12.5% soybean extract. Each treatment consisted of 4 replications. Parameters observed were the thickness and fiber content of nata and then analyzed using ANOVA (Analysis of Variance). Based on the results of the study, the addition of soybean extract (Glycine max L.) had an effect on the thickness and fiber content of nata de cane compared to the control treatment. The resulting Nata has a chewy texture and a distinctive aroma of fragrant sugarcane juice. The highest thickness and fiber content of nata de cane was obtained in the 12.5% soybean extract treatment, namely 1.58 cm and 2.95% and has met the quality requirements of SNI 01-4317-1996. Overall, the most preferred nata de cane organoleptic test result was nata de cane with the addition of soybean extract at a concentration of 12.5% in the very like category. The reseach results can be recommended to the public that soybean extract has the potential as an alternative to ZA in the process of making nata.

Abstract

Abstract: Citrus Vein Phloem Degeneration (CVPD) disease outbreaks in citrus are one of the limiting factors in conventional vegetative cultivation. This affects the availability of plant material for cultivation, which in turn impacts the productivity and sustainability of Siam Pontianak orange cultivation. Micropropagation through indirect somatic embryogenesis in liquid medium is expected to produce a larger number of disease-free seedlings. Cells from embryogenic callus have the potential to develop into new individuals and are widely used for plant propagation and genetic manipulation. This study aims to determine the best treatment combination for embryogenic callus propagation in solid medium and to observe embryo development in cell suspension culture. The study used a completely randomized design (CRD) consisting of two stages: (1) micropropagation of embryogenic callus on Murashige Skoog (MS) solid medium suplemented with of 0.5 ppm 2,4-D + 0.5 ppm kinetin; 0.5 ppm 2,4-D + 1.5 ppm kinetin; 1.0 ppm 2,4-D + 1.0 ppm kinetin; 1.5 ppm 2,4-D + 1.5 ppm kinetin; and 2.0 ppm 2,4-D + 2.0 ppm kinetin; and (2) proliferation and development of somatic embryos in cell suspension culture on liquid MS medium with the following treatments: without Plant Growth Regulators (D0K0); 1.0 ppm kinetin (D0K1); 0.5 ppm 2,4-D + 1.0 ppm kinetin (D0.5K1); 1.0 ppm 2,4-D (D1K0); and 1.0 ppm 2,4-D + 1.0 ppm kinetin (D1K1). The results showed that the medium with 1.0 ppm 2,4-D + 1.0 ppm kinetin produced the highest average fresh weight (0.568 g), which was significantly different from all other treatments. Somatic embryo formation was observed in all suspension culture treatments 14 days after culture (DAC). Observations at 42 DAC showed that embryo development in the 1.0 ppm 2,4-D + 1.0 ppm kinetin treatment had reached the heart stage (60%), while the other treatments showed embryos only at the globular stage. Abstrak: Serangan penyakit Citrus Vein Phloem Degeneration (CVPD) pada tanaman jeruk merupakan salah satu faktor penghambat dalam budidaya vegetatif konvensional. Ketersediaan bahan tanaman, khususnya dalam budidaya jeruk Siam Pontianak, sangat penting bagi produktivitas dan keberlanjutan budidayanya. Perbanyakan melalui indirect somatic embryogenesis dari kalus embriogenik pada media cair dapat menghasilkan bibit yang bebas penyakit dalam jumlah lebih besar. Sel kalus bersifat embriogenik yang diinduksi dari eksplan kotiledon pada media MS dengan penambahan 2,4-D dan kinetin memiliki potensi untuk berkembang menjadi individu baru. Penelitian ini bertujuan memperoleh kombinasi perlakuan terbaik sebagai media perbanyakan kalus embriogenik serta mengamati perkembangan embrio pada kultur suspensi sel. Penelitian menggunakan Rancangan Acak Lengkap (RAL) terdiri atas 2 tahap, yaitu: (1) optimasi perbanyakan kalus embriogenik pada media padat MS dengan penambahan 0,5 ppm 2,4-D + 0,5 ppm kinetin; 0,5 ppm 2,4-D + 1,5 kinetin; 1,0 ppm 2,4-D + 1,0 ppm kinetin; 1,5 ppm 2,4-D + 1,5 ppm kinetin, dan 2,0 ppm 2,4-D + 2,0 ppm kinetin; serta (2) proliferasi dan perkembangan embrio somatik pada kultur suspensi sel pada media MS cair dengan perlakuan: tanpa penambahan Zat Pengatur Tumbuh (D0K0); 1,0 ppm kinetin (D0K1); 1,0 ppm 2,4-D (D1K0); 0,5 ppm 2,4-D + 1,0 ppm kinetin (D0,5K1), dan 1,0 ppm 2,4-D + 1,0 ppm kinetin (D1K1). Hasil penelitian menunjukkan bahwa media dengan kombinasi 1,0 ppm 2,4-D + 1,0 ppm kinetin menghasilkan rerata berat basah kalus terbesar (0,568 g) dan berbeda nyata dengan semua perlakuan.  Persentase pembentukan embrio somatik sebesar 100% terlihat pada semua perlakuan kultur suspensi umur 14 hari setelah tanam (hst). Pengamatan pada 42 hst menunjukkan bahwa perkembangan embrio pada perlakuan 1,0 ppm 2,4-D + 1,0 ppm kinetin telah mencapai tahap jantung (60%), sedangkan perlakuan lainnya hanya menunjukkan embrio pada tahap globular.
