Aglonema merupakan tanaman hias yang memiliki berbagai macam variasi daun, baik dari motif, bentuk, warna dan ukurannya. Aglonema sp. var Red Borju mempunyai daya tarik pada daun yang berwarna hijau tua dan merah muda pada tulang daunnya. Tanaman ini mempunyai nilai ekonomis yang cukup tinggi, namun budidayanya masih terbatas. Teknik kultur jaringan dengan penambahan bahan organik merupakan salah satu alternatif perbanyakan tanaman Aglonema sp. untuk memenuhi permintaan pasar yang semakin meningkat. Dengan teknik kultur jaringan bisa didapatkan bibit tanaman dalam jumlah yang banyak, seragam sehat dan dalam waktu yang lebih singkat. Bahan organik yang ditambahkan ke dalam media dapat digunakan sebagai zat pengatur tumbuh alami yang membantu pertumbuhan tanaman. Penelitian ini bertujuan untuk mengetahui jenis dan konsentrasi bahan organik bawang merah (Allium cepa) dan taoge (Phaseolus radiatus) terbaik terhadap pertumbuhan eksplan Aglonema sp. Varietas Red Borju secara in vitro. Hasil penelitian menunjukkan bahwa penambahan bahan organik bawang merah lebih berpengaruh terhadap pertumbuhan tanaman Aglonema sp. Varietas Red Borju dibanding bahan organik taoge. Konsentrasi terbaik untuk pertumbuhan tanaman diperoleh pada penambahan bahan organik bawang merah 25 g/L yaitu pada penambahan tinggi tanaman 7,4 cm, jumlah tunas 6 tunas, jumlah akar 6,3 akar dan jumlah daun 3 helai. Hal ini berarti bahwa pemberian bahan organik bawang merah dengan konsentrasi rendah (25 g/L) dapat meningkatkan pertumbuhan tanaman Aglonema sp. secara in vitro.

Bawang merah (Allium ascalonicum L.) merupakan komoditas sayuran yang memiliki banyak manfaat dalam bidang pangan dan pengobatan. Untuk memaksimalkan pemanfaatan bawang merah sebagai tanaman obat, digunakan bahan berupa kalus yang diperoleh melalui teknik kultur jaringan. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi sukrosa terhadap pertumbuhan kalus, kandungan senyawa metabolit sekunder, dan aktivitas antioksidan bawang merah. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan konsentrasi sukrosa, yaitu 0, 15, 30, 45, dan 60 g/L dalam media Murashige Skoog (MS) yang ditambahkan zat pengatur tumbuh (ZPT) pikloram 5 mg/L + kinetin 3 mg/L. Setiap perlakuan diulang lima kali sehingga total percobaan sebanyak 25 unit. Pengujian meliputi induksi kalus, uji fitokimia (alkaloid, fenolik, flavonoid, saponin, steroid-triterpenoid), dan uji aktivitas antioksidan. Hasil penelitian menunjukkan bahwa penambahan sukrosa 30 g/L memberikan hasil terbaik dalam menginduksi kalus, dengan rata-rata waktu tumbuh kalus 33,6 hari, tekstur kalus remah-kompak, warna kalus kuning, dan berat rata-rata kalus 0,583 ± 0,278 g. Kandungan metabolit sekunder meliputi alkaloid, fenolik, flavonoid, dan saponin. Aktivitas antioksidan mencapai 17,691 ppm, yang termasuk dalam kategori antioksidan sangat kuat.

Borneo prima tangerine (Citrus reticulata) is a plant species from East Kalimantan, which is expected to become one of the leading citrus in the country. The obstacle to developing this citrus is that cultivation is still limited, so efforts are needed to cultivate plants using in vitro techniques. The process of plant multiplication has been done, the next step is rooting. The purpose of this research is to know the type and concentration of plant growth regulators (PGR) that are optimal in stimulating root growth in Borneo prima tangerine plants. This study used a completely randomized design consisting of 9 treatments, namely control (without the addition of PGR), the addition of natural PGR raja banana extract with concentrations of 25; 50; 75; and 100 g/L, synthetic PGR Naphthalene Acetic Acid (NAA) concentrations of 0.5; 1.0; 1.5; and 2.0 mg/L, each treatment with 3 replicates. The results showed the addition of raja banana extract 75 g/L produced the fastest root emergence time of 3.33 days, the addition of NAA 0.5 mg/L produced the highest number of roots, namely 4.67 roots, and plantain extract 50 g/L produced the longest roots, namely 4.50 cm. This means that the addition of raja banana extract gives the best results in inducing root formation.

Earthquake and tsunami have high risk level in Padang State that predict earthquake 8.9 Richter of MentawaiMegatrust. Padang State Senior High School 2 located in Red Zone of earthquake and tsunami and also close withBanda Bakali River. There are still found some students whose have not expressed enough knowledge related toearthquake and tsunami preparedness and not ready if disaster occur. This study aims to determine therelationship of knowledge and attitude with preparedness to confront earthquake and tsunami risk on students atPadang State Senior High School 2. Research design used analytics descriptive with cross sectional studyapproach to 280 respondents. The instrument of research consisted of 4 parts of questionnaire, which aredemographics data, knowledge, attitude, and preparedness. Research analysis used a comparative test by usingsoftware computer. The results of this study showed that 55.4% had high knowledge, 53.2% good attitudes, and66.1% moderate preparedness.

Introduction: Pregnancy in adolescents has the potential risk of disrupting psychological well-being. Understanding how psychological well-being is conceptualized and assessed among adolescents, as well as identifying influential factors, is essential for developing appropriate and effective interventions. This review aims to map the conceptual approaches and assessment methods used to evaluate psychological well-being among pregnant adolescents and to identify influential factors associated with psychological well-being during pregnancy. Methods: The study procedures were carried out using a scoping review that followed the Joanna Briggs Institute approach. Literature searches included terms from Emtree, MeSH, and CINAHL headings across 5 databases, including Embase, Medline (Ovid), CINAHL, Cochrane, and ScienceDirect until April 2024. After the search, a total of 8 studies were included, which met the needed criteria. Results: This review identified 5 conceptual approaches used to understand and assess psychological well-being in pregnant adolescents, namely (i) self-esteem, (ii) measures on anxiety, depression, emotional bonding, general positive affect, and the absence of psychological distress, (iii) discrimination experiences, self-perceptions, and social barriers experienced, (iv) positive and negative mood concepts, and (v) positive psychological functioning. The results showed that several factors were associated with psychological well-being of pregnant adolescents, including educational level, neighborhood support, financial constraints, rejection from close people, trust, and attachment with caregiver. Conclusion: This review shows the need for a more comprehensive and multidimensional approach to conceptualizing and assessing psychological well-being in pregnant adolescents. The complexity of this issue demands a thorough and inclusive approach that focuses on individual and social factors. Keywords: adolescent pregnancy; psychological well-being; adolescent growth and development
