Abstract

Keberadaan ruang terbuka hijau perkotaan penting untuk menciptakan lingkungan yang nyaman di tengah isu pemanasan global dan peningkatan populasi. Salah satu faktor penting yang memengaruhi kenyamanan pengunjung taman kota adalah kondisi iklim mikro. Penelitian ini bertujuan untuk menganalisis kondisi iklim mikro, menghitung indeks kenyamanan (THI), dan menganalisa persepsi pengunjung terhadap tingkat kenyamanan pada Taman Ulin, Taman PAUD, dan Taman Pintar di Kota Tenggarong, Kabupaten Kutai Kartanegara. Data iklim mikro (intensitas cahaya, suhu udara, dan kelembapan udara) diukur langsung di lapangan, sedangkan persepsi pengunjung dikumpulkan melalui survei. Hasil penelitian menunjukkan tiga taman kota yang diteliti memiliki kondisi iklim mikro yang berbeda disebabkan perbedaan jumlah vegetasi yang ditanam pada setiap taman kota. Indeks kenyamanan di Taman Ulin (27,66), Taman PAUD (28,02), dan Taman Pintar (27,88) termasuk dalam kategori “nyaman”. Persepsi pengunjung terhadap kenyamanan berdasarkan indikator iklim memiliki rata-rata penilaian secara berturut-turut di Taman Ulin sebesar 4,32 (kategori sangat baik), Taman PAUD sebesar 2,84 (kategori kurang baik), dan Taman Pintar sebesar 4,13 (kategori baik). Informasi kondisi iklim mikro dan persepsi pengunjung serta tingkat kenyamanan pada taman kota dapat dijadikan bahan pertimbangan dan menjadi rekomendasi bagi pemerintah daerah dalam pengelolaan dan perencanaan taman kota yang lebih baik, termasuk penempatan vegetasi, kawasan teduh, dan fasilitas pendukung lainnya, dengan mempertimbangkan kebutuhan masyarakat dan prinsip-prinsip kenyamanan iklim.

Abstract

Spodoptera frugiperda (FAW) is the main threat to the early vegetative phase of corn in North Gorontalo. This research aims to develop a typology of adaptive strategies based on local knowledge, serving as the foundation for contextual and affordable PHT recommendations. The qualitative approach is employed through a combination of focused ethnography, Participatory Rural Appraisal (PRA), and Grounded Theory analysis. Data were collected in three sub-districts (Kwandang, Gentuma Raya, Atinggola) through 28 in-depth interviews, 7 FGDs, 5 PRA sessions, and 9 farm-walks with purposive snowball sampling. The results indicate the presence of a "practical threshold" used by farmers: checking 20 random plants/beds every 5–7 days and acting if ≥5 plants are symptomatic or damaged yields a score of 3–4. Thematic coding resulted in three adaptive strategies: preventive (simultaneous planting, garden cleanliness, intercrops/cover crops), reactive (ash/sand shoots treatment, selective spray), and integrative (simple monitoring → plant treatment → measurable spray with MOA rotation). The ranking matrix places simultaneous planting, observation-based spraying, and simple monitoring as the most effective strategies according to farmers. The main obstacles include the simultaneous planting, limited scouting personnel, high cash costs, and a lack of affordable monitoring equipment. The drivers are group leadership, regular meetings, and small demonstration plots. The research resulted in a 6-step protocol that was agreed upon at the group/overlay level and was well-received because it was simple. The findings emphasized the need to strengthen monitoring, simultaneous planting coordination, and information curation (WA kiosk extensions) so that adaptive practices develop into collective habits.

Abstract

This study aims to analyze the effectiveness of biopesticides based on local endophytic microorganisms as an environmentally friendly alternative in controlling Spodoptera frugiperda pests in corn plants. The study was conducted using a qualitative approach based on library research, reinforced by field data from previous studies and simulations of comparative field tests between endophytic biopesticide treatments and chemical pesticides. Data were analyzed descriptively and comparatively by reviewing control effectiveness, crop productivity, and the environmental efficiency index (EI). The results showed that endophytic biopesticides containing isolates of Bacillus subtilis and Trichoderma harzianum were able to reduce the intensity of S. frugiperda attacks by up to 65.8%, approaching the effectiveness of synthetic chemical pesticides (79.4%). In addition, the endophytic biopesticide treatment produced an average harvest of 7.42 tons/ha with an EI of 0.92, indicating a much lower ecological impact compared to chemical pesticides (EI of 0.45). These results indicate that local endophytic biopesticides are agronomically effective, environmentally safe, and have great potential for application in integrated pest management (IPM) systems in corn cultivation in Indonesia.

Abstract

The increasing worldwide demand for natural products in fields ranging from pharmaceuticals to food industry has made clear an urgent necessity of more effective and sustainable production technologies. In this regard, the gamma-ray technology is a very promising Biotechnological tool of choice. Because of its effective physical mutation and unique biological effects, gamma irradiation has been responsible for more than 60% of professionally released mutant crop verities. This approach possesses the potential to exploit the mutagenic effects of ionizing radiation, and to cause genetic diversity in plants for their agronomic traits such as yield productivity and specifically at large scale, the enhancement of important secondary metabolite profiles. The utility of gamma rays goes beyond mutations induction: as an elicitor, they cause dramatic physiological and molecular responses in plants leading to the overproduction of bioactive compounds. The mode of action may be through the generation of DNA damage, e.g., single and double strand breaks, which runs a novel pathway or activates an alternative one leading to enhanced production of certain secondary metabolites. This review intended to comprehensively discuss the versatile bioprocesses of gamma irradiation, biological mechanisms underlying its action and how this effect interprets into metabolite production, crop quality and overall agricultural sustainability. The application of this technology provides a promising option not only to improve the productivity high-value natural products but also the development of new plant germplasms with enhanced resilience (or stress tolerance) that is relevant for securing food production in an era of climate change.

Abstract

This study aims to determine the effect of mixing Merkubung and Red Meranti wood particles on the dimensional stability of particleboard. Particle cement boards were made using conventional methods with Merkubung and Meranti Merah particle ratios of 100:0, 0:100, and 50:50 (in %), with a target board density and thickness of 1.2 g/cm³ and 12 mm. The weight ratio of particles to cement was 1:3 with a compression pressure of 20 bar. Dimensional stability testing was carried out by testing the thickness swelling properties of the boards in accordance with ISO 8335 (1987) standards. The test results showed that the boards produced were uniform in thickness, density, and moisture content. The mixing of Merkubung and Red Meranti wood particles in equal proportions of each type of wood particle showed a significant effect. Meanwhile, Merkubung particle cement boards had no significant effect on Red Meranti particle cement boards. In terms of utilization, if particle cement boards are to be used, Merkubung wood particles cannot be mixed with Red Meranti wood particles.

Abstract

The agribusiness sector plays a strategic role in economic development and national food security. However, interest among the younger generation in this sector tends to decline, especially amid the rapid advancement of digital technology. This study aims to analyze the interest and perceptions of young people, particularly university students, toward the agribusiness sector in the digital era. A quantitative survey with a descriptive approach was conducted, involving respondents from various faculties within a university setting. The results indicate that although most respondents have a positive perception of agribusiness potential, their willingness to engage directly in the sector remains low. Factors such as limited understanding of digital opportunities in agribusiness, minimal exposure to modern agribusiness practices, and the dominance of industrial and service sectors in career aspirations contribute to this lack of interest. The study recommends integrating digital technology into agribusiness education and actively promoting digital-based agribusiness innovations to attract youth engagement.

Abstract

The application of arbuscular mycorrhizal fungi can enhance the fertility of peat soils and reduce the requirement for NPK fertilization on the plat. The study aimed to evaluate the role of AMF in improving the growth and yield of bird’s eye chili and in supporting NPK fertilizer efficiency on peat soil. The experiment was conducted in Pontianak City, West Kalimantan, from July to November 2024, using a factorial completely randomized design. The first factor consisted of three levels of AMF application without AMF, AMF sourced from pineapple vegetation, and AMF sourced from weed vegetation. The second factor consisted of four levels of NPK fertilizer dosage 100% recommended NPK, 75% recommended NPK, 50% recommended NPK, and 25% recommended NPK. The results showed that the application of AMF significantly improved the growth and yield of bird’s eye chili on peat soil and enhanced the efficiency of NPK fertilization. The interaction between AMF and NPK dosages indicated that plants inoculated with AMF, particularly AMF from pineapple vegetation, exhibited greater plant height, higher plant dry weight, earlier flowering, and higher fruit weight per plant compared to plants without AMF across all fertilizer levels. The most optimal effect of AMF was observed at the 50% NPK dosage, which produced the best growth and yield performance, indicating that AMF application can reduce chemical fertilizer requirements without compromising crop productivity.
