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

Nagari Campago is located in Limakoto Subdistrict, Kampung Dalam, Padang Pariaman Regency. The area has great potential in agriculture, because there is a large area of wetland agriculture for white rice cultivation and dry land for chili plants and other seasonal crops. However, the reality that happened to Nagari Campago was that several times the harvest period, farmers experienced pests and diseases that resulted in crop failure. Farmers have limited information on red rice cultivation. The purpose of this activity is for Nagari Campago farmers to gain knowledge and understanding about brown rice, farmers can recognize and be able to make vegetable pesticides that can be used to control plant pests and diseases, thereby reducing maintenance costs. This activity was carried out in Nagari Campago, Limokoto Subdistrict, Kampung Dalam, Padang Pariaman Regency, West Sumatra Province. The method used is lecture, demonstration, discussion, monitoring. Socialization of the benefits of brown rice and demonstration training on the manufacture of vegetable pesticides to partners of the “Bukik Caliak Indah” farmer group. The result of the implementation of the activity is that the community is very interested in the cultivation of organic red rice and chili. The community is able to make their own botanical pesticides to control plant pests and diseases. From the results of the activity, it can be concluded that farmers are aware of environmentally friendly cultivation, and alternative sources of food crops.

Abstract

Farmers commonly use inorganic fertilizers such as urea, rock phosphate, and NPK in crop cultivation. Continuous use of these inorganic fertilizers can degrade the quality of the growing medium and increase production costs. Inorganic fertilizers are also relatively expensive. One way to address this issue is by utilizing allelochemical compounds as Liquid Organic Fertilizers (LOF) for plant cultivation. Applying fertilizers in liquid form is more easily absorbed by plants because they are already dissolved and readily available. Babandotan liquid organic fertilizer contains essential nutrients such as nitrogen (N), phosphorus (P), and potassium (K). These elements play a crucial role in stimulating vegetative growth, promoting root development, and strengthening the plant's overall health. The objective of this activity is to enhance the knowledge of the members of the Banda Langik Women Farmers Group about liquid organic fertilizer made from Babandotan weed, as well as to fulfill the Higher Education Tri Dharma for lecturers in the Agrotechnology Program at the Faculty of Agriculture, Andalas University. This community service activity was conducted at the Banda Langik Women Farmers Group, located at Jl. Ekora RT01/RW07 Sungai Bangek, Balai Gadang Village, Koto Tangah District, Padang City, in May-June 2022. The activities performed included preparation, socialization, closing, and reporting. Based on the results of the activity, several key points were identified, including that the community service program was conducted according to the needs of the Women Farmers Group, the group was satisfied and found the service beneficial for their development in the future, and the group members were committed to using LOF in their cultivation areas.

Abstract

Soybean (Glycine max L.) is a type of nutritious food crop because soybean seeds have high protein amino acid content. Increasing domestic production for soybean self-sufficiency needs to be done by expanding the planting area. The objective of this research is to examine the effect of ethyl methane sulfonate concentration and obtain soybean plants tolerant to drought and aluminum stress through in vitro selection. This research was conducted from November 2023 to January 2024 at the Tissue Culture Laboratory, Faculty of Agriculture, Andalas University. The research was arranged in a Completely Randomized Design consisting of 12 treatment levels of the combination of concentrations of abiotic selection agents PEG 4000 and AlCl3 induced by EMS mutation and 12 treatment levels of the combination of concentrations of abiotic selection agents PEG 4000 and AlCl3 not induced by EMS mutation with 3 replications. Data analysis was performed using independent sample t-test at a significance level of 5% and interpreted descriptively. The results showed that mutation induction using ethyl methane sulfonate (EMS) did not produce soybean somatic embryo mutants tolerant to drought and aluminum stress. Meanwhile, results from non-mutated callus produced somatic embryos suspected to be potential putative somaclonal candidates tolerant to drought and aluminum after double in vitro selection using 10% PEG 4000 and 150 ppm AlCl3 selection agents.

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
