Abstract

The maintenance of peat swamp forest ecosystems' ability to function has become more important throughout the last ten years. a global issue mostly associated with the loss of nutrients and the emission of greenhouse gases into the environment. Peat forests are becoming more and more degraded as a result of high land fires, illicit logging, and the severity of peatland conversion. Every year, peat swamp forests are destroyed by fires that contribute to smog and global warming, making the issue a national and even global one. The restoration of degraded peat swamp forests using Dyera lowii Hook, an endemic peat swamp forest species and a companion type of vegetation that grows in the following time in the process of peat swamp forest development, should be an attempt to address this issue. The pH of the soil is quite acidic, and peat swamp forests are typically degraded with some nutrients, making it difficult for plants to flourish. Because of this, technology must be incorporated through the use of biological fertilizers, specifically mycorrhizae. The purpose of this study is to investigate the mycorrhizal species that most successfully promote the growth of peat indigenous D. lowii plants, as there is currently no evidence of research on the subject. Using a completely randomized design model (CRD) and mycorrhizal treatment, the study employed an experimental methodology; M0 = without mycorrhiza, M1 = Glomus sp1, M2 = Glomus sp 2, M3 = Glomus sp 3, M4 = Glomus sp 4 and M5 = Gigaspora sp. repeated 5 times. Planting tests were carried out at the Silvicultural Laboratory screen house of the Faculty of Forestry, Tanjungpura University. The study's findings demonstrate that the best Arbuscular Mycorrhizal Fungus for promoting the growth of D. lowii plants in nurseries is Glomus sp. 3.Keywords: arbuscular mycorrhizal fungi, dyera lowi, peatsoils.AbstrakPengurasan hara, serta pelepasan gas rumah kaca ke atmosfer telah menjadi fokus perhatian global selama sepuluh tahun terakhir untuk menjaga kelestarian fungsi ekosistem hutan rawa gambut. Semakin banyak hutan gambut terdegradasi karena konversi lahan gambut, penebangan liar, dan kebakaran hutan dan lahan yang tinggi. Hutan rawa gambut yang terdegradasi terbakar setiap tahun, yang menyebabkan kabut asap dan pemanasan global, yang merupakan masalah di tingkat nasional dan internasional. Pemulihan hutan rawa gambut yang telah terdegradasi harus dilakukan. Jelutung (Dyera lowii Hook) adalah salah satu jenis pohon yang tinggal di hutan rawa gambut, adalah jenis vegetasi penyerta yang tumbuh pada tahap berikutnya dari proses pembentukan hutan rawa gambut. Sebagian besar, hutan rawa gambut telah terdegradasi, menyebabkan beberapa unsur hara kahat dan pH tanah sangat masam. Akibatnya, tanaman menjadi sulit untuk tumbuh. Untuk mencapai hal ini, teknologi seperti pemanfaatan mikoriza, yang merupakan pupuk hayati, diperlukan. Penelitian ini dilakukan untuk mengidentifikasi jenis mikoriza paling berhasil meningkatkan tumbuh tanaman jelutung endemik gambut karena belum ada penelitian yang meneliti jenis mikoriza mana yang paling efektif meningkatkan pertumbuhan tanaman jelutung. Penelitian melakukan eksperimen dengan model rancangan acak lengkap (RAL) dengan perlakuan jenis mikoriza; M0= tanpa mikoriza, M1= Glomus sp1, M2= Glomus sp 2, M3= Glomus sp 3, M4= Glomus sp 4dan M5= Gigaspora sp. diulang sebanyak 5 kali ulangan. Laboratorium Silvikultur Fakultas Kehutanan Universitas Tanjungpura memiliki rumah kasa tempat pengujian penanaman dilakukan. Hasil penelitian menunjukkan bahwa jenis Glomus sp 3 adalah jenis jamur mikoriza arbuskula terbaik untuk mempercepat pertumbuhan tanaman jelutung di persemaian.Kata Kunci: fungi mikoriza arbuskula, jelutung, gambut

Abstract

[ID] Pembangunan ruko di Kota Pekanbaru berkembang dengan sangat pesat. Pengguna dan pengembang ruko merupakan pihak yang terlibat langsung dengan fenomena ini. Pihak pengguna dan pengembang ruko mempunyai pertimbangan dalam melakukan pemilihan terhadap lokasi ruko. Pertimbangan tersebut merupakan faktor-faktor penting yang dianggap sangat menentukan dalam memilih lokasi ruko. Oleh karena itu, peneliti ingin mengetahui faktor-faktor apa saja yang menjadi preferensi bagi pengguna ruko. Dalam penelitian ini digunakan pendekatan deduktif dengan metode analisis kuantitatif . Penelitian ini dimulai dari teori-teori yang sudah ada kemudian meneliti kondisi di lokasi studi. Untuk pengguna ruko, sampel ditetapkan terlebih dahulu dan dipilih secara random. Penelitian dilakukan terhadap pengguna ruko di tujuh (7) kecamatan yang mempunyai jumlah ruko paling dominan dikota Pekanbaru selama lima tahun. Berdasarkan hasil analisis, ditemukan bahwa semua faktor yang terkandung dalam teori, memang merupakan faktor-faktor yang dianggap menentukan oleh pengguna dalam melakukan pemilihan terhadap lokasi ruko. namun tidak semua sub faktor tersebut merupakan faktor-faktor yang dianggap menentukan oleh pengguna ruko. Dalam menilai faktor-faktor pemilihan lokasi ruko tersebut,secara garis besar terjadi persamaan preferensi diantara pengguna ruko. Faktor yang sangat menentukan yaitu tersediannya jaringan listrik, sangatlah penting karena merupakan salah satu pemenuhan kebutuhan hidup yang dimanfaatkan untuk sumber energi dalam menunjang berbagai macam aktivitas manusia. [EN] The development of ruko (house and shop in the same building) has been very rapid in all cities in Indonesia. The users and investors of ruko were the parties involved directly in the phenomena. In deciding the location of ruko to be built, the users and investors had important factors they took into their consideration including very determinant factors. The researcher wish to discover the preference of the factors to the users. In this research, deductive method was employed using quantitavive analysis. The research reviewed the existing theories and then compared them with the reality. For ruko users, samples were determinded and chosen randomly. The research was also conducted to the ruko users in 7 district that had the highest number of ruko ini Pekanbaru for five years .The result of researc h showed that all factors determining the location of ruko which were proposed in the theories were considered the determinant factors by users, but not all sub factors were considered. In assesing factors, users have the similar preference. Very determinant factor according to users is the availability of the power grid, it is important because it is one of subsistence which is used for energy resources in supporting a wide range of human activities.

Abstract

Varietas semangka hibrida memiliki produktivitas dan keseragaman yang tinggi sehingga diminati oleh konsumen. Penelitian ini bertujuan untuk mengevaluasi beberapa hibrida hasil persilangan antara galur inbrida dengan varietas Serif Saga Agrihorti (SSA) sebagai tetua jantan. Percobaan menggunakan rancangan acak kelompok (RAK) dengan tiga ulangan, melibatkan 12 hibrida hasil topcross dan Serif Saga Agrihorti (SSA) sebagai satu varietas pembanding. Semua genotipe ditanam di lapangan dengan mengikuti praktik agronomi semangka yang standar. Karakteristik yang diamati meliputi waktu berbunga jantan dan betina, umur panen, serta diameter dan bobot buah, ketebalan kulit buah, tingkat kemanisan, dan jumlah biji fertil dan biji steril. Data dianalisis menggunakan ANOVA dilanjutkan dengan uji BNT (Beda Nyata Terkecil). Variabilitas genotipik dan fenotipik, heritabilitas dan koefisien korelasi genotipik dan fenotipik  karakter, diestimasi berdasarkan partisi nilai ragam dari ANOVA. Hasil penelitian menunjukkan variabilitas genetik yang luas pada karakter umur berbunga jantan dan betina, serta bobot buah. Nilai duga heritabilitas yang tinggi diperoleh pada karakter umur berbunga jantan dan betina, bobot buah, diameter buah dan jumlah biji fertil. Empat genotipe hibrida yaitu G1, G6, G8, dan G10, menunjukkan bobot buah dan tingkat kemanisan yang lebih tinggi dibandingkan varietas SSA. Berdasarkan heritabilitas yang tinggi pada karakter bobot buah, maka keempat hibrida ini berpotensi untuk dikembangkan menjadi varietas semangka hibrida baru atau dimanfaatkan sebagai populasi dasar untuk perakitan varietas bersari bebas.

Abstract

Patchouli (Pogostemon cablin Benth.) is among the top 20 essential oil-producing plants traded in the global market. This plant shows narrow genetic diversity due to non-flowering and seed production, increasing the challenges in obtaining new varieties through crossbreeding. Therefore, this research aimed to apply mutation method using ultraviolet-C irradiation combined with tissue culture to broaden the genetic diversity of patchouli. The potential of UV-C irradiation and the morphological changes occurring in the plant were explored from October to December 2023 at the Tissue Culture Laboratory, Andalas University, Padang. In addition, the experiment was arranged in a Randomized Complete Block Design (RCBD) with 10 treatment levels and 3 groups. The treatments included UV-C irradiation doses of 0 (wild type), 30, 60, 90, 120, 150, 180, 210, 240, and 270 minutes at a distance of 30 cm. Data for each patchouli plant per observation variable were presented as mean values, variance, and standard deviation and analyzed using an unpaired t-test. The results showed that exposure to ultraviolet-C radiation impacted several morphological characteristics, such as chlorosis, delayed bud development, increased bud and leaf count, as well as faster bud growth. This phenomenon shows the potential of ultraviolet-C radiation as a physical mutagenic agent.

Abstract

LSD disease is caused by the DNA virus of the genus Capripox from the family poxviridae. This disease is transmitted in various ways, one of which is a vector bite. It is suspected that drum flies and wild animals such as rats in drums play a role in spreading this disease within one drum or in a larger area. According to tests that have been carried out and existing theories, this disease is also excreted in livestock products, for example saliva, milk and semen directly, and also spreads indirectly through the use of non-sterile livestock equipment and human power (REF). (search about whether it has gone so far and the samples used and the results at the Wates bbvet. Cases of LSD disease have spread to almost all regions in Java and have been confirmed by the competent ministry. This article contains findings from residents' reports to local agencies who submitted requests for examination starting from physical signs, clinical symptoms, Real Time Polymerase Chain Reaction (RT-PCR) examination as well as histopathological examination of a biopsy of skin tissue where the nodule lesion was formed. RT-PCR examination to confirm the presence of the virus from swab samples and lesion scrapings as well as histopathological examination is carried out to ensure the formation of intracytoplasmic inclusion bends as one of the characteristic features of LSD disease.
