Abstract

Museum adalah bangunan yang memamerkan benda-benda pameranpameran yang menarik perhatian publik. Seperti warisan sejarah, artistik , dan ilmu atau bisa disebut tempat penyimpanan barang-barang lama. Pembangunan Museum POLRI dilakukan atas usulan dari Kapolri Jendral Polisi Bambang Hendarso Danuri. Tujuannya untuk menjaga kelestarian nilai-nilai sejarah dari polisi Indonesia untuk generasi selanjutnya. Penelitian ini berfokus pada pemecahan masalah yang dialami Museum POLRI yakni terjadinya penumpukan antrian karena kurangnya jumlah pemandu yang mengakibatkan penurunan kepuasan pelanggan. Karena permasalahan tersebut peneliti melakukan simulasi menggunakan AnyLogic dan melakukan empat skenario dengan mengubah variable jumlah pengunjung dan jumlah pemandu dengan adanya simulasi ini di harapkan jumlah antrian yang ada pada museum POLRI akan berkurang.

Abstract. Cahyadi MA, Yunus A. 2025. Antioxidant profile of several local rice varieties from Central Java, Indonesia, under biotic stress conditions of bacterial leaf blight. Asian J Agric 9: 368-376. Central Java harbors diverse local rice germplasm that requires preservation, yet their resistance to bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) remains underexplored. Antioxidant activity has been linked to BLB resistance, indicating its potential as a screening tool for identifying tolerant varieties in breeding programs. This study examined four local rice varieties inoculated with Xoo, focusing on catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), total flavonoids, and total phenolic compounds. Based on lesion length, Mentik Susu (MS) and Rojolele (RL) were resistant, while Merah Segreng (MSeg) and Hitam Mutiara (HM) showed moderate resistance. At 5 days post-inoculation (dpi), the highest CAT activity (0.019 units/mg protein) occurred in MSeg, while at 20 dpi HM showed the highest (0.014 units/mg protein). For POD, RL exhibited the highest activity (0.271 units/mL protein) at 5 dpi, and MSeg at 20 dpi (0.436 units/mL protein). The highest SOD activity at 5 dpi was observed in HM (169.35 units/mg protein), whereas MS peaked at 20 dpi (157.95 units/mg protein). These enzymatic antioxidant levels did not differ significantly among varieties, but non-enzymatic antioxidants—flavonoids and phenolics—showed significant variation, with MS and RL containing 44.30 and 27.09% more flavonoids and 25.88 and 18.91% more phenolics, respectively, than moderately resistant varieties. These findings indicate that non-enzymatic antioxidants contribute more prominently to BLB resistance than enzymatic ones, and that varieties rich in flavonoids and phenolic compounds, such as Mentik Susu and Rojolele, have stronger resistance, highlighting their potential for breeding programs to enhance tolerance against bacterial leaf blight while supporting the conservation and utilization of Central Java’s local rice diversity.

Abstract

The Kepok Unti Sayang variety is a superior type of banana that is resistant to fusarium wilt. The high demand for Kepok Unti Sayang needs to be balanced with good seed production. One of the methods used for multiplying superior seeds of Kepok Unti Sayang is through tissue culture. This research aims to obtain the optimal concentration of Naphtaleine Acetic Acid (NAA) in the subculture media for the growth of root numbers in the Kepok Unti Sayang Banana. The second objective is to determine the optimal concentration of Benzyl Amino Purine (BAP) in the subculture medium for shoot number growth in Kepok Unti Sayang bananas. Another goal is to identify the best treatment combination that can produce the highest number of shoots in Kepok Unti Sayang bananas. The research was conducted at the Laboratory of Plant Physiology and Biotechnology at Sebelas Maret University from February to July 2025. The study was conducted with 4 levels of NAA treatment: 0; 0.5; 1; and 1.5 ppm. The BAP treatment was administered at 4 levels: 0; 1; 2; and 3 ppm. The variables observed in this study were the time of shoot emergence, number of shoots, time of root emergence, root length, and final height of the planlet. Data from each variable were then analyzed using analysis of variance (ANOVA) with an F-test at a significance level of 95%. Significantly different data were then followed by Duncan's Multiple Range Test (DMRT) at a significance level of 95%. The significant combination of NAA and BAP on the observed variables was then reanalyzed using regression tests. The results showed that the application of various concentrations of NAA does not affect the growth of the number of roots of Kepok bananas var. Unti Sayang. The application of 2 ppm BAP is optimal for the growth of the number of shoots of Kepok bananas var. Unti Sayang. The interaction between 1 ppm NAA and BAP at 1-2 ppm produces the most optimal average shoot emergence time.

Abstract

Barangan banana is a banana variety that has high economic value, but its production is still carried out conventionally, resulting in limited barangan bananas on the market. The use of tissue culture methods can quickly produce high-quality, disease-free plants regardless of seasonal conditions. The aim of this research is to determine the effect of providing the best ZPT IAA and BA for the growth of the Barangan banana planet. The research was conducted in August-October 2023 at the Biotechnology and Plant Physiology Laboratory, Sebelas Maret University. This research used a two-factor Completely Randomized Design (CRD) with 6 replications. The first factor was the use of ZPT Indole Acetic Acid (concentrations 0, 0.5, 1, and 1.5 ppm and the second factor was the use of ZPT Benzyl Adenine (0, 0.5, 1, 1.5 ppm). The variables observed were root emergence time, number of roots, root length, time of leaf emergence, number of leaves, time of shoot emergence, number of shoots, and height of shoots. The observed data were analyzed using Analysis of Variance (ANOVA) with a 5% level test and if there was a significant difference, it was continued with Duncan's Multiple Range Test (DMRT) at the level 5%. The results showed that giving 0.5 ppm IAA increased root length; 0.5 ppm IAA was given optimally for root formation; and 1 ppm IAA increased the shoot height of the Barangan banana plnalet. Giving BA 0.5 ppm root number; BA 1, 5 ppm produces the highest number of leaves; BA 1 ppm increases shoot height of barangan banana plantlets.
