Abstract

Suboptimal soil conditions can lead to reduced latex production and quality. One of the main factors influencing latex production is soil fertility, where fertile soil with adequate nutrient content can enhance latex yield. One of the efforts to improve production is through proper fertilization, where the dosage and timing of phosphorus (P) and potassium (K) application must align with the needs of the rubber plant and the condition of the soil. By using appropriate P and K fertilizers, rubber farmers can increase both latex yield and quality. This research was conducted using a factorial experiment with a randomized complete block design (RCBD) and three replications. The first factor was the amount of TSP fertilizer, divided into four categories: P0 = without TSP application per tree, P1 = 175 g per tree, P2 = 200 g per tree, and P3 = 225 g per tree. The second factor was the dose of KCl fertilizer, consisting of four categories: K0 = control, K1 = 200 g per tree, K2 = 250 g per tree, and K3 = 300 g per tree. The findings indicated that TSP fertilizer application had a significant effect on dry rubber content, while KCl doses did not show a significant effect on latex volume, wet latex weight, dry latex weight, or dry rubber content.

Abstract

Abstract Banana (Musa sp) is one of the tropical fruit types originating from Southeast Asia. Bananas have a high enough potential to be managed intensively, because they have become an export and import trading business in the international market.Tissue culture is a method of plant propagation conducted vegetatively in a synthetic medium under sterile conditions (in vitro). Acclimatization is a period of adaptation of plantlets from in vitro (controlled environment) culture media to the open spaces before being planted in the field. One of the factors that influence the success of plantlets acclimatization is the use of the right media composition so that it can produce good plants. This study was conducted to determine the effect of growth of bananas (Musa acuminnata cv. Barangan) resulting from acclimatization with the use of variations in cow manure growing media. The research was using a completely randomized design (CRD) with a single factor. The factor was the treatment of planting media composition (soil: husk: cow manure) consisting of 8 levels: S1 = 1:1:1, S2 = 1:1:2, S3 = 1:2:1, S4 = 1:2:2, S5 = 2:1:1, S6 = 2:1:2, S7 = 2:2:1, S8 = 4:2:1. Variables observed included plant height, leaf number, leaf length, leaf width, and stem diameter. Data were analyzed by analysis of various test levels of 5% and further analysis of Duncan's Multiple Range Test (DMRT). The results showed that the treatment comparison of the composition of the planting medium, soil: husk: cow manure did not significantly affect the growth of barangan banana plants. In the treatment of comparison of the composition of soil: husks: cow manure (1:2:1) gives higher results and better results on all variable variables observed Keywords: Growth; manure; tissue culture

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.
