Abstract

Phalaenopsis merupakan salah satu anggrek yang terkenal karena keindahan bunganya dengan variasi warna yang tinggi dan periode pembungaan yang lama. Salah satu masalah dalam budidaya anggrek adalah Penyakit Busuk Lunak (PBL) yang disebabkan oleh bakteri Dickeya dadantii. Induksi resistensi dengan Asam Salisilat (AS) merupakan metode alternatif dalam mengendalikan PBL pada Phalaenopsis. Penelitian ini dilaksanakan pada bulan November 2018 sampai Maret 2019, di Laboratorium Kultur Jaringan Tanaman, Departemen Agronomi dan Hortikultura IPB. Penelitian terdiri dari dua percobaan. Percobaan 1 bertujuan untuk mengevaluasi keragaman respon planlet in vitro asal biji hasil penyerbukan sendiri P. amabilis terhadap D. dadanti dengan inokulasi pada daun terpisah dan menentukan tingkat ketahanannya. Sebanyak 7 dari 158 planlet yang diuji, memiliki respon agak tahan terhadap D. dadantii, sedangkan sisanya rentan atau sangat rentan. Percobaan 2 bertujuan untuk membandingkan respon bibit P. amabilis terhadap D. dadantii pada 1 hari setelah perlakuan asam salisilat (AS) pada konsentrasi 0, 15, 30, 45, 60, 75, dan 90 ppm menggunakan metode inokulasi daun pada bibit yang masih menempel di tanaman. Percobaan 2 menggunakan rancangan acak kelompok lengkap teracak (RKLT). Hasil penelitian menunjukkan perlakuan AS 75 ppm paling baik dalam menginduksi ketahanan bibit P. amabilis terhadap patogen penyebab busuk lunak D. dadantii. Tanaman pada perlakuan tersebut menghasilkan nilai CFU dan AUPDC lebih rendah dan aktivitas peroksidase lebih tinggi dibanding perlakuan lainnya. Kata kunci: daun terpisah, daun pada tanaman, keparahan penyakit, metode inokulasi, penyakit busuk lunak

Abstract

Tanaman dengan pertambahan tinggi yang lambat merupakan karakter penting dalam program pemuliaan kelapa sawit dan brasinosteroid merupakan hormon penting yang berpengaruh untuk karakter tersebut. Gen sterol metiltransferase 1 (SMT1) merupakan salah satu gen kunci dalam biosintesis brasinosteroid. Pengembangan marker molekuler dapat dimulai dengan identifikasi dan karakterisasi gen yang terkait dengan karakter target. Penelitian ini bertujuan untuk mengisolasi dan mengkarakterisasi keragaman nukleotida gen SMT1. Amplifikasi PCR dilakukan menggunakan genom Elaeis oleifera (E.o.), E. guineensis (E.g.) dan hibrida dari keduanya (E.g. x E.o.) dengan sepasang primer spesifik gen SMT1. Dalam penelitian ini berhasil diamplifikasi satu potongan DNA gen SMT1 dan dari hasil DNA sequencing berhasil diidentifikasi sebanyak 501- 505 pb. Potongan DNA yang diidentifikasi terdiri atas partial intron 8, exon 9, intron 9, dan patial exon 10, yang menyandi antara 104-105 residu asam amino. Domain residu asam amino terkonservasi ditemukan dalam hasil translasi amplikon, yang berkorelasi dengan situs aktif dalam biosintesis brasinosteroid dan mengkonfirmasi identitas amplikon sebagai bagian dari gen SMT1. Keragaman nukleotida potongan DNA gen SMT1 yang teridentifikasi berpotensi dapat digunakan untuk pengembangan marker molekuler yang bermanfaat untuk pemuliaan tanaman kelapa sawit, terutama untuk karakter pertambahan tinggi tanaman yang lambat. Kata kunci: Brasinosteroid, sterol, tanaman kerdil

Abstract

Leaf morphological characters and nutrient content in leaf tissue can vary depending on plant genotype. The nutrient solution culture can produce leaves with good nutritional content. Therefore, this research aimed to evaluate and validate cassava putative mutants' morphological traits and Zn content using a nutrient solution culture system. This research was carried out from January to May 2022 at the greenhouse of Cikabayan Experimental Garden, IPB University, Bogor. This study used two cassava cultivars and ten mutant genotypes from the cassava research team of IPB University, resulting from mutation breeding by gamma irradiation. The plant characters observed in this study included the number of leaves, length and width of the leaflet, leaf colour, plant height, fresh and dry weight leaf, and analysis of Zn content. The data were analyzed using ANOVA at a significant level of α = 5%, followed by Tukey's further test. The results showed that the G2D1-422 genotype had a higher Zn content than the wild type (Ratim/G2) and the other genotypes. The high Zn genotypes (G2D1-422) and low Zn genotypes (Ratim (G2) had not significantly different in fresh and dry leaf weight. Meanwhile, the plant genotype did not affect other growth characteristics such as plant height, the number of leaves, and the length and width of the leaflets, and overall, the characters were similar between the observed genotypes.

Abstract

This study aims to analyze the dynamics of social relations and forms of adaptation of local communities to the presence of the mining company PT. Bumi Suksesindo (PT BSI) in Sumberagung Village, Pesanggaran District, Banyuwangi Regency. The presence of the gold mining industry has significantly changed the social, economic, and cultural structure of the community. This study uses a qualitative approach with a case study method, through data collection techniques in the form of field observations, in-depth interviews with the community, company officials, and government officials, as well as documentation. Data analysis was conducted interactively through the stages of data reduction, data presentation, and conclusion drawing. The results of the study show that the social relationship between the community and PT BSI is dynamic and complex, reflecting a process of negotiation between economic, social, and ecological interests. The community showed three main patterns of response to the presence of the mine: (1) cooperative, through involvement in corporate social responsibility (CSR) programs; (2) adaptive, by adjusting economic and social activities to changes in their living space; and (3) resistant, through rejection or criticism of the perceived environmental and social impacts. These patterns form a layered configuration of social relations between the community, the company, and the government, in which processes of accommodation and conflict occur simultaneously. This study concludes that the success of social relations between mining companies and local communities is highly dependent on two-way communication, policy transparency, and respect for the social values and local wisdom of the community. The implications of this study emphasize the importance of participatory social interaction models as the basis for equitable and sustainable community-corporate relationship management in mining areas

Abstract

This study aims to analyze the practices and impact of a humanistic approach in learning to develop the potential of students at MI Nailul Huda, Jimbaran-Badung. The humanistic approach, which emphasizes respect for the individual, is considered relevant to the principles of Islamic education. This qualitative research utilized a Focus Group Discussion (FGD) method with five teachers from MI Nailul Huda serving as subjects. The data were analyzed thematically to identify the understanding, practices, and impact of this approach. The findings indicate that the implementation of the humanistic approach successfully created a positive learning environment, strengthened teacher-student interpersonal relationships, and significantly enhanced students' self-confidence, creativity, and empathy. The study found that this approach aligns with the concept of fitrah (human nature) in Islam and the educational vision proposed by al-Ghazali. However, challenges such as a dense curriculum and cognitive-oriented assessment remain major obstacles. The research recommends continuous training to strengthen the consistent implementation of this approach.

Abstract

This study examines the discrepancy between das sollen and das sein regarding the obligation to register a business license as mandated in Article 15(1) of Government Regulation Number 80 of 2019. Although the regulation requires all business actors to register their licenses with the Central Government, its implementation in Malang City remains ineffective. Of approximately 85,200 MSMEs, only about 22,000 had obtained official licenses by 2024. The study addresses two issues: (1) the factors contributing to the low compliance of micro-enterprise actors with licensing requirements, and (2) the legal implications for those operating without a business license. Using a socio-legal method with a juridical-sociological approach, the research relies on primary and secondary data collected through fieldwork and literature study. The sample consists of 13 respondents and 2 key informants, analyzed qualitatively. The findings reveal that the main cause of ineffective implementation is the low level of legal awareness and knowledge among micro-enterprise actors. Eight respondents were unaware of the obligation to register with the Disnaker PMPTSP of Malang City, while five respondents were aware but had not complied. This demonstrates that regulatory implementation has not been optimal. The legal implications for non-compliant business actors include the loss of legal validity of their operations and the potential imposition of administrative sanctions under applicable laws.

Abstract

This research aims to analyze the influence of price on purchasing decisions at the Tomika 7 minimarket. Price is an important factor in influencing consumer behavior, especially in the context of fiercely competitive minimarkets. The research method used is a quantitative method with a survey approach. Data was collected through a questionnaire distributed to 100 respondents who were Tomika 7 minimarket customers. The research results showed that price had a significant influence on purchasing decisions. Factors such as affordability, suitability of price to product quality, and promotions or discounts are the main elements that influence customer perceptions of price. Data analysis using linear regression shows that the price variable contributes 65% to purchasing decisions, while the rest is influenced by other factors such as location, service and product variety. Thus, Tomika 7 minimarkets are advised to continue to maintain a competitive pricing strategy and provide added value through discounts or customer loyalty programs to improve consumer purchasing decisions.
