KOMUNIKASI PEMASARAN SEBAGAI FAKTOR PEMBENTUK CITRA MEREK: STUDI KASUS PADA PT. BPR MITRA KANAKA SANTOSA BANDUNG
Full text linkThis study aims to analyze the effect of marketing communication on brand image at PT. BPR Mitra Kanaka Santosa Bandung, focusing on three dimensions: public relations, advertising, and personal selling. The research is motivated by the increase in promotional activities that have not yet resulted in significant improvements in brand image or customer growth. A quantitative method with a survey approach was employed. The sample consisted of 73 active savings customers selected using probability sampling from a total population of 350 customers. Data were collected using a closed ended questionnaire with a Likert scale, and analyzed using path analysis. The results show that, partially, only personal selling has a significant influence on brand image. Public relations and advertising do not have a significant effect. Simultaneously, the three marketing communication variables do not significantly affect brand image. These findings indicate that direct, personal marketing strategies are more effective in building brand image than one-way communication approaches such as advertising or public relations

Analisis Determinasi Kemiskinan di Kabupaten/Kota Yogyakarta 2018–2023
Full text linkPoverty remains a major issue in the Special Region of Yogyakarta (DIY), which has the highest percentage compared to other provinces on the island of Java. This condition indicates an inequality in welfare that needs to be studied, particularly in terms of education, health, and employment. This study aims to analyze the effect of Literacy Rate (LR), Life Expectancy (LE), and Open Unemployment Rate (OUR) on poverty levels in five districts/cities in DIY. Using a quantitative approach with secondary panel data from the Central Statistics Agency (BPS), the analysis was conducted using Fixed Effect panel data regression through EViews 12 software. The results show that the OUR has a significant positive effect on poverty levels, while the LFR and HLE have a negative but insignificant effect. These findings confirm that unemployment is the most dominant factor in determining poverty levels in DIY. The implication is that poverty alleviation policies should focus on creating productive jobs, aligning education with labor market needs, and equalizing access to health care to strengthen the socio-economic resilience of the community. Kemiskinan masih menjadi isu utama di Daerah Istimewa Yogyakarta (DIY) yang persentasenya paling tinggi daripada provinsi lain di Pulau Jawa. Kondisi ini menunjukkan adanya ketimpangan kesejahteraan yang perlu dikaji, khususnya dari aspek pendidikan, kesehatan, dan ketenagakerjaan. Penelitian ini bertujuan untuk menganalisis pengaruh Angka Melek Huruf (AMH), Angka Harapan Hidup (AHH), dan Tingkat Pengangguran Terbuka (TPT) terhadap tingkat kemiskinan di lima kabupaten/kota di DIY. Melalui pendekatan kuantitatif dengan data panel sekunder dari Badan Pusat Statistik (BPS), analisis dilakukan menggunakan regresi data panel model Fixed Effect melalui perangkat lunak EViews 12. Hasil penelitian menunjukkan bahwa TPT berpengaruh positif signifikan terhadap tingkat kemiskinan, sementara AMH dan AHH berpengaruh negatif namun tidak signifikan. Temuan ini menegaskan bahwa pengangguran merupakan faktor paling dominan dalam menentukan tingkat kemiskinan di DIY. Implikasinya, kebijakan pengentasan kemiskinan sebaiknya difokuskan pada penciptaan lapangan kerja produktif, penyelarasan pendidikan dengan kebutuhan pasar kerja, serta pemerataan akses kesehatan untuk memperkuat ketahanan sosial ekonomi masyarakat
Implementasi Program Sekolah Rakyat di Kota Bengkulu: Analisis Fiskal, Sosial, dan Pendidikan
Full text linkThis study aims to analyze the implementation of the People's School (Sekolah Rakyat, SR) Program in Bengkulu City, which is an educational initiative with a boarding school model targeting poor and extremely poor communities. The research applies a descriptive qualitative approach by supporting primary data from student surveys and secondary data from official government documents, the Regional Fiscal Study (Kajian Fiskal Regional, KFR), and statistics from the Central Bureau of Statistics (BPS). The findings indicate that the SR Program in Bengkulu has successfully enhanced students’ learning motivation, academic performance, discipline, and self-confidence, while also reducing the financial burden on their families. Large-scale fiscal investments through state budget allocation and direct assistance to students have generated positive impacts in both educational and socio-economic domains. However, major challenges include dependence on the state budget (APBN), limited availability of qualified teachers, disparities in general educational infrastructure, and insufficient socialization in remote areas. Penelitian ini bertujuan untuk menganalisis implementasi Program Sekolah Rakyat (SR) di Kota Bengkulu, yang merupakan inisiatif pendidikan berbasis asrama untuk masyarakat miskin dan miskin ekstrem. Pendekatan penelitian menggunakan metode kualitatif deskriptif dengan dukungan data primer dari survei kepada siswa serta data sekunder dari dokumen resmi pemerintah, laporan Kajian Fiskal Regional (KFR), dan data Badan Pusat Statistik (BPS). Hasil penelitian menunjukkan bahwa Program SR di Bengkulu berhasil meningkatkan motivasi belajar, prestasi akademik, disiplin, dan rasa percaya diri siswa, serta meringankan beban ekonomi keluarga. Investasi fiskal yang besar melalui alokasi APBN dan bantuan langsung kepada siswa telah memberikan dampak positif, baik di bidang pendidikan maupun sosial-ekonomi. Namun, tantangan utama meliputi ketergantungan pada APBN, keterbatasan tenaga pendidik berkualitas, kesenjangan infrastruktur pendidikan umum, serta keterbatasan sosialisasi di daerah terpencil
Pengaruh Konsentrasi dan Frekuensi POC Biofouling Tiram Mutiara terhadap Kerapatan Stomata Hotong (Setaria italica (L.)
Full text linkKetersediaan nutrisi berperan penting dalam mengatur fungsi fisiologis tanaman, termasuk pembentukan dan kerapatan stomata yang memengaruhi efisiensi fotosintesis serta penggunaan air. Salah satu sumber nutrisi organik potensial adalah Pupuk Organik Cair (POC) berbasis biofouling Tiram Mutiara, yang mengandung unsur hara esensial seperti nitrogen, fosfor, dan kalium. Penelitian ini bertujuan untuk menganalisis pengaruh konsentrasi dan frekuensi aplikasi POC biofouling Tiram Mutiara terhadap kerapatan stomata tanaman hotong (Setaria italica (L.)). Penelitian dilaksanakan di Desa Mamala, Kabupaten Maluku Tengah, dari Oktober 2023 hingga Januari 2024, menggunakan rancangan acak kelompok lengkap (RAKL) dua faktor, yaitu konsentrasi POC (0, 10, 20, dan 30 mL/L) serta frekuensi aplikasi (satu kali pada 25 Hari Setelah Tanam [HST] dan dua kali pada 25 dan 50 HST). Hasil analisis varians menunjukkan bahwa kedua faktor berpengaruh signifikan terhadap kerapatan stomata, tinggi tanaman, dan jumlah daun. Perlakuan P3W2 (30 mL/L, dua kali aplikasi) memberikan nilai tertinggi dengan kerapatan stomata 366,67 stomata/cm². Hasil ini menunjukkan bahwa peningkatan konsentrasi dan frekuensi aplikasi POC biofouling meningkatkan aktivitas fisiologis tanaman melalui pembentukan stomata yang lebih padat dan efisien. Dengan demikian, POC biofouling Tiram Mutiara berpotensi digunakan sebagai pupuk organik ramah lingkungan yang mendukung pertumbuhan dan efisiensi fotosintesis tanaman hotong. Nutrient availability plays a crucial role in regulating plant physiological functions, including stomatal formation and density, which directly affect photosynthetic efficiency and water use. One promising organic nutrient source is Pearl Oyster biofouling-based liquid organic fertilizer (POC), which contains essential elements such as nitrogen, phosphorus, and potassium. This study aimed to examine the effects of different concentrations and application frequencies of Pearl Oyster biofouling POC on the stomatal density of foxtail millet (Setaria italica (L.)). The research was conducted in Mamala Village, Central Maluku Regency, from October 2023 to January 2024, using a randomized complete block design (RCBD) with two factors: POC concentration (0, 10, 20, and 30 mL/L) and application frequency (once at 25 Days After Planting [DAP] and twice at 25 and 50 DAP). Analysis of variance revealed significant effects of both factors on stomatal density, plant height, and leaf number. The highest stomatal density (366.67 stomata/cm²) was observed in treatment P3W2 (30 mL/L applied twice). These findings indicate that higher concentrations and more frequent applications of biofouling-based POC enhance plant physiological activity by promoting denser and more efficient stomatal development. Therefore, Pearl Oyster biofouling POC can serve as an environmentally friendly organic fertilizer that supports improved growth and photosynthetic efficiency in Setaria italica (L.).Ketersediaan nutrisi berperan penting dalam mengatur fungsi fisiologis tanaman, termasuk pembentukan dan kerapatan stomata yang memengaruhi efisiensi fotosintesis serta penggunaan air.

Full text linkAgeratum conyzoides, and Imperata cylindrica are cosmopolite weeds in agricultural land that can reduce the productivity of cultivated plants. This study aims to analyze the effect of A. conyzoides leaves biomass and I. cylindrical former plant media on the percentage of germination and growth of mung beans (Vigna radiata). The research was conducted by making 3 (three) replications of each Treatment. Treatment A (application of A. conyzoides leaf biomass to the planting media), Treatment B (used I. cylindrica planting media), and Control Treatment. Anova test and Tukey HSD test were conducted using R-Studio. The results showed that Treatments (A) and (B) reduced the success of mung bean germination compared to the control (97%), with A at 60% and B at 50%. The changes in leaf number and root length are very noticeable compared to plant height. The allelopathic effect was stronger in A than B. Biomass of A. conyzoides and used media of I. cylindrica has the potential to inhibit germination and early growth of mung beans.Ageratum conyzoides, and Imperata cylindrica are cosmopolite weeds in agricultural land that can reduce the productivity of cultivated plants. This study aims to analyze the effects of A. conyzoides leaf biomass and I. cylindrica grown in the planting medium on the germination percentage and growth of mung beans (Vigna radiata). The research was conducted by making 3 (three) replications of each treatment. Treatment A involves a planting medium mixed with A. conyzoides leaf biomass, Treatment B consists of a used planting medium overgrown with I. cylindrica, and the Control Treatment serves as a reference. ANOVA test and Tukey HSD test were conducted using R-Studio. The results indicated that both Treatments A and B reduced the germination success of mung beans compared to the control group, which had a germination rate of 97%. Treatment A achieved only a 60% germination rate, while Treatment B recorded 50%. Notable changes were observed in leaf number and root length, while plant height changes were less significant. The allelopathic effect was stronger in Treatment A than in Treatment B. The biomass of A. conyzoides and the used media from I. cylindrica demonstrated potential to inhibit the germination and early growth of mung beans. This study also emphasizes the potential of utilizing allelopathic compounds from both species as environmentally sustainable bioherbicides. Their use can reduce chemical exposure, reduce production costs, and maintain the ecosystem. These bioherbicides have the opportunity to be integrated into integrated pest management (IPM) strategies in food crops to support sustainable agriculture

Keanekaragaman Artropoda pada Berbagai Kombinasi Pola Tanam Jagung Ketan dan Edamame
Full text linkSistem tanam monokultur yang umum diterapkan petani cenderung menurunkan kestabilan agroekosistem karena meningkatnya risiko serangan hama dan penyakit. Salah satu alternatifnya ialah sistem polikultur yang dapat memperkaya habitat bagi berbagai jenis artropoda, termasuk musuh alami hama. Penelitian ini bertujuan untuk menganalisis keanekaragaman artropoda pada berbagai kombinasi tanam jagung ketan dan kedelai edamame dengan tambahan tanaman border serai dan kemangi. Penelitian dilaksanakan pada empat tipe lahan pertaniandi Kebonsari, Jember, Jawa Timur: 1) monokultur jagung ketan, 2) polikultur jagung ketan-edamame, (3) polikultur jagung ketan-edamame dengan border serai, dan 4) polikultur jagung ketan-edamame dengan border kemangi. Pengambilan sampel dilakukan menggunakan pitfall trap, yellow trap, dan sweep net, sedangkan data dianalisis menggunakan indeks keanekaragaman (H'), kemerataan (E), dan dominasi (C). Hasil menunjukkan bahwa perlakuan polikultur bersamaan dengan border tanaman aromatik terbukti meningkatkan keseimbangan komunitas arthropoda yang menguntungkan. Polikultur kemangi efektif meningkatkan parasitoid, sedangkan polikultur serai lebih optimal dalam meningkatkan predator dan penyerbuk. The monoculture system commonly practiced by Indonesian farmers tends to reduce agroecosystem stability due to the higher risk of pest and disease. On the other hand, polyculture can provide a more diverse habitat that supports beneficial arthropods, including natural enemies. This study aimed to analyze the diversity of arthropods in various planting combinations of waxy maize and edamame with additional border plants of lemongrass and basil. The research was conducted from June to September 2024 in Kebonsari, Jember, East Java, using four treatments: (1) maize monoculture, (2) maize–edamame polyculture, (3) maize–edamame polyculture with lemongrass borders, and (4) maize–edamame polyculture with basil borders. Arthropod sampling was carried out using pitfall traps, yellow traps, and sweep nets, and data were analyzed using the diversity index (H'), evenness index (E), and dominance index (C). The results showed that the polyculture combined with aromatic plants as a border effectively enhanced the balance of beneficial arthropod communities. Polyculture with basil effective in increasing parasitoid abundance, while polyculture with lemongrass is more optimal in increasing predators and pollinators.
