2026-01-19T06:08:29+07:00

Coffee is a strategic plantation commodity in Indonesia, whose quality is strongly influenced by fruit maturity at harvest. However, maturity assessment in the field is still largely conducted manually, leading to subjectivity and low efficiency. This study aims to analyze the performance of YOLOv8 in detecting three coffee fruit maturity levels—unripe, semi-ripe, and ripe—and to evaluate the impact of different training configurations on model performance. The experiments were conducted using the public “Coffee Cherry” dataset from Kaggle, consisting of 432 images with 1000 bounding box annotations. Several configurations were evaluated, including YOLOv8 variants (n, s, m), image sizes, batch sizes, number of epochs, and data augmentation techniques based on HSV color space, object scaling, and mixup. The results show that YOLOv8s provides the best balance between detection accuracy and computational efficiency. The optimal configuration was achieved using an image size of 416, batch size of 8, and 30 epochs, with augmentation improving recall and mAP@50, particularly for challenging classes. Nevertheless, limited dataset size and diversity remain the main constraints affecting performance. Overall, YOLOv8 demonstrates strong potential for coffee fruit maturity detection under real-world conditions.

Octopus is one of the important fishery commodities in the Alas Strait, West Nusa Tenggara, which has high economic value and plays a role in the marine ecosystem. This study aims to identify and characterise octopus species caught in the Alas Strait based on morphometric and taxonomic characters. Sampling was conducted at seven fishing locations in the Alas Strait, namely Gili Lebur, Pulau Kambing, Pulau Panjang, Pulau Belang, Gili Belang, Pasir Putih, and Gili Ular. A total of 29 individual octopuses were collected and analysed based on morphometric characters, including body weight, head length (HL), mantle length (ML), HL/ML ratio, body colour, and key taxonomic characters. The identification results showed that all octopus specimens caught in the Alas Strait belonged to one species, namely Octopus cyanea (Gray, 1849), which is a member of the family Octopodidae and Genus Octopus. The main diagnostic characters found include the presence of oceli on the arm crown, white to light blue spots on the lateral surface of the arms, zebra stripes on the latero-ventral surface, and HL/ML ratios ranging from 15.8–42.9%. The specimens found consisted of 16 adult individuals and 13 juvenile individuals, with body weights ranging from 0.33–2.70 kg and mantle lengths of 7–22 cm.

Self-regulation is the fundamental skills that you need in your day-to-day life to control your emotions and behavior as well focused your attention on work. For some ADHD children, especially those with associated learning disabilities, self-regulation can present an even greater challenge, requiring parents most optimal involvement. The objective of the study was to explore parental strategies regarding the development of self-regulation in children with an empirical diagnosis of ADHD and intellectual disabilities (ID) by means of a literature review approach. this research method is a qualitative literature review by analysis: deliberately scrutinizing scientific sources. Parenting strategies that increase children`s self-regulation skills as clear parenting practices, daily routine, positive reinforcement with rats and when parents use emotional coaching (attention) to kids and parent modeling of their willingness to self-regulate such behaviours. Moreover, enhancing factors such as parental awareness, family support, school coordination and professional help reinforce the effectiveness of these strategies. Parenting stress, lack of knowledge, low financial status and social stigma are the major challenges that may slow down the developmental process. In conclusion, at least for children diagnosed with attention-deficit/hyperactivity disorder and intellectual disabilities, a concert between family, school and social environment is needed to maximize children cognitive-emotional-social development toward self-regulation

ANALISIS KEBUTUHAN PARKIR DI WILAYAH PASAR KARANG SUKUN

2026-07-17T05:45:02+07:00

This study aims to determine the parking capacity and requirements for Karang Sukun Market in Mataram City, West Nusa Tenggara. It is a survey-based study employing a quantitative descriptive approach, conducted at the market from March 5 to March 12, 2025. The results indicate that parking volume and accumulation values fluctuated across the observed time periods and days. However, peak values generally occurred during the market's operational hours of 08:00–12:00 WITA, with a subsequent decline between 13:00 and 17:00 WITA. Parking capacity was sufficient on Tuesdays (both morning and afternoon) and Thursday afternoons (13:00–17:00), but proved inadequate on Mondays, Wednesdays, and Fridays. Fridays saw the highest visitor density, with a total of 668 vehicles parking. On average, the parking capacity at Karang Sukun Market was insufficient to meet demand; the facility accommodates 133 vehicles, whereas the average number of parked vehicles was 194. Due to this lack of adequate parking space, motorists resorted to parking along the streets surrounding the market, causing traffic congestion during peak hours.

Giant gourami (Osphronemus goramy) is one of the most economically important freshwater fish species widely cultured in Indonesia. The success of giant gourami culture is strongly influenced by water quality, particularly dissolved oxygen availability, which can be improved through aeration. This study aimed to analyze the effect of aeration intensity on the growth and feed utilization efficiency of giant gourami (Osphronemus goramy) juveniles. The research was conducted from March to April 2026 at the Wet Laboratory, Faculty of Fisheries, Universitas 45 Mataram. An experimental method with a Completely Randomized Design (CRD) was used, consisting of four treatments and three replications. The treatments included P0 (without aeration), P1 (one air stone), P2 (two air stones), and P3 (three air stones). The results showed that the highest absolute weight growth was obtained in treatment P3, reaching 0.80 g/day, while the lowest was observed in P0 at 0.65 g/day. The highest absolute length growth was also recorded in P3 at 0.23 cm/day, whereas the lowest was found in P0 at 0.14 cm/day. The best FCR value was obtained in treatment P1 with a value of 1.98, while the highest feed utilization efficiency (FUE) was also observed in P1 at 50.42%. ANOVA results indicated that different aeration intensities did not significantly affect (Sig. >0.05) either weight growth or length growth of giant gourami juveniles. Treatment P3 resulted in the best growth performance, while treatment P1 provided the most efficient feed utilization.
