The purpose of this study was to determine how the application of Local Microorganisms (LOM) from stale rice and oil palm boiler ash impacts the growth and production of shallots (Allium ascalonicum L.) and to determine the interaction between the two treatments. Shallots are a horticultural commodity with high economic value, so efforts are needed to increase production through the use of environmentally friendly organic materials. The study used a factorial Randomized Block Design (RBD) with two factors and three replications. The first factor was LOM from stale rice with four levels (0, 20, 40, and 60 ml/L water/plot) and the second factor was oil palm boiler ash with four levels (0, 500, 1000, and 1500 grams/plot), resulting in 16 treatment combinations and 48 experimental plots. The parameters observed included plant height, number of leaves, number of tillers, fresh weight of bulbs, dry weight of bulbs, and bulb diameter. If there was a significant effect, the data were tested using analysis of variance (ANOVA). This research is expected to produce scientific data on the use of organic waste as an environmentally friendly fertilizer alternative.

separating and shredding organic and inorganic waste. This study aims to analyze the process of shredding household waste using the Computational Fluid Dynamics–Discrete Element Method (CFD-DEM) and determine the optimal operational parameters based on variations in rotor speed. The research method uses numerical simulation with SolidWorks 2024 software for geometric modeling and Ansys Rocky 2023 R1 for CFD-DEM simulation. The rotor speed variations used are 1000 RPM, 2500 RPM, and 4000 RPM with a mass flow rate of 4 tons/hour and a simulation duration of 2 seconds. The parameters analyzed included particle mass flow rate, shredding characteristics, and power consumption. The simulation results showed that a speed of 1000 RPM produced the most optimal performance with a maximum capacity of ±4 tons/hour and a stable shredding response compared to other variations. At 2500 RPM, there were high fluctuations with low capacity (±0.6 tons/hour), while at 4000 RPM, the capacity was moderate (±1.1 tons/hour) but still did not exceed the performance of 1000 RPM. Based on these results, it can be concluded that a rotor speed parameter of 1000 RPM is the most effective condition for improving the grinding efficiency and production capacity of a hammer mill-type Depackaging machine based on CFD-DEM simulation.

Waste management has become a critical environmental issue at both global and national levels due to increasing population and changing consumption patterns. In Indonesia, waste generation exceeds 60 million tons annually, with a significant portion consisting of plastic waste that requires hundreds of years to decompose. One of the main challenges in addressing this issue is the low level of public awareness and understanding regarding waste types and their decomposition time. This community service program conducted by students of Universitas Negeri Padang aims to improve environmental awareness through environmental education and community empowerment using an innovative visual medium in the form of waste decomposition time educational boards. The activity was implemented in Pasar Hilir Hamlet, Lumindai Village, using a participatory approach involving observation, socialization, board design, production, and installation. The results indicate that the program successfully enhanced community knowledge regarding the differences between organic and inorganic waste and their environmental impacts. The educational boards, placed in strategic locations near waste disposal areas, function as effective visual tools that continuously deliver information and reinforce environmentally responsible behavior. In addition, this program contributes to improving environmental cleanliness, strengthening community participation, and increasing environmental literacy. Therefore, the innovation of waste decomposition time educational boards serves not only as an informative medium but also as a sustainable educational tool to promote long-term behavioral change toward environmental awareness.

The farmer empowerment program in Dilem Village, Gondang District, was implemented through training on the production of solid compost based on livestock manure as an effort to enhance the independence and agricultural productivity of the local farming community.

The implementation methods included socialization activities, material delivery, hands-on practice in compost production, and post-training assistance to ensure the sustainability of technology application at the farmer level. The results of the program indicated an increase in farmers’ knowledge and skills in the compost-making process, enabling them to produce organic fertilizer independently and reduce dependence on chemical fertilizers. This program also had a positive impact on soil quality, production cost efficiency, environmental cleanliness, and supported environmentally friendly and sustainable agricultural practices. Thus, this training activity contributes to strengthening the local economy, improving farmers’ welfare, and developing a sustainable agricultural system based on local resources in Dilem Village in a continuous and practical manner.

Household waste management in Gondang Village remains a major problem because waste is not sorted from the source and supporting facilities are still limited, resulting in mixed organic, inorganic, and residual waste, potentially polluting the environment. To support the planned development of a 3R Waste Management Site (TPS 3R) in 2026, a community service activity was conducted aimed at increasing community knowledge, awareness, and readiness regarding waste sorting and the application of the Reduce, Reuse, and Recycle concept. This activity used a participatory approach through outreach, waste sorting demonstrations, installation of educational boards on waste decomposition times, and the provision of separate trash bins in four hamlets. The results of the activity showed an increase in community understanding of waste types, 3R principles, and long-term environmental impacts, accompanied by positive responses and high enthusiasm. The educational boards and facilities provided served as visual reminders that encouraged behavioral change, making this activity an important first step in preparing the Gondang Village community towards sustainable waste management through the 3R Waste Management Site (TPS 3R).

The 2025 Real Work Lectures use the Berdampak model (Real Work Lectures based on Community Impactful). The theme of our group's Community Service Program is the problem of household waste management in Bakalan Village, Gondang District, Mojokerto Regency, which requires proper handling. Open burning of waste causes air pollution and other adverse effects. In an effort to overcome this problem, KKN students have initiated the use of used barrels as a place to burn waste with minimal smoke. This program includes observation and socialization related to innovative technology in waste management. Through this activity, the community is introduced to the use of trash cans that reduce smoke pollution and produce briquettes as an alternative fuel from combustion residues. The program results show an increase in community awareness of waste management and the potential for reducing negative environmental impacts. This innovation opens up opportunities for the community to become a model of independent and sustainable waste management, which can be applied in other villages.

This research is prompted by legal complications within civil procedural law, specifically regarding the failure of judges to identify formal defects in special powers of attorney during the preliminary stages of trial. The central focus of this study examines Decision Number 14/Pdt.G/2025/PN Kba, in which a lawsuit was declared inadmissible (Niet Ontvankelijke Verklaard) only after a seven-month litigation process that had already progressed through evidentiary hearings and local inspections. The objective is to evaluate the effectiveness of the dominus litis principle in empowering judges to provide procedural guidance for lawsuit amendments, while testing its alignment with the principles of simple, fast, and low-cost justice. Employing a normative legal research method with statutory and case-based approaches, the legal materials are analyzed qualitatively using the legal syllogism technique. The findings indicate that the application of the dominus litis principle in the a quo case remains ineffective due to the judges' passive and formalistic tendencies. Such an approach neglects the ex-officio authority mandated under Articles 119 and 132 of the HIR. This ineffectiveness results in significant judicial inefficiency, causing undue loss of time and financial resources for justice seekers. Consequently, this study recommends strengthening rigorous initial screening mechanisms by the panel of judges at the first hearing. This preventive measure is essential to curb the waste of judicial resources and ensure the realization of substantial justice for all disputing parties.

The implementation of Clean and Healthy Living Behavior (PHBS) begins at an early age, particularly among school children, who learn extensively from their surrounding environment through the School Health Program (UKS). Although the family is the primary unit in shaping PHBS habits, parents’ busy schedules often lead children to interact more with teachers and peers at school. This study aims to determine the effectiveness of the UKS program on students’ PHBS at SD Lambaro Angan, Darussalam District, Aceh Besar Regency in 2024. This research employed a cross-sectional design with a population of 321 students and a sample of 76 respondents. Data collection was conducted on March 4, 2024. The results indicate that the UKS program has a significant effect on students’ PHBS, including habits such as washing hands with running water and soap, purchasing healthy snacks at the school canteen, disposing of waste properly, participating in physical exercise, not smoking at school, eliminating mosquito larvae, and using school sanitation facilities (p < 0.05). However, no significant effect was found on activities such as weighing body weight and measuring height. In conclusion, the UKS program is effective in improving students’ PHBS. These findings are expected to provide input for schools to optimize the implementation of UKS and enhance PHBS promotion so that students can apply clean and healthy living behaviors in their daily lives.

Vannamei shrimp (Litopenaeus vannamei) is one of the most important aquaculture commodities with high economic value and strong market demand. The transportation of broodstock shrimp is a critical stage that may affect survival due to decreased oxygen levels and water quality deterioration. High stocking density during transportation can accelerate oxygen depletion and increase metabolic waste, leading to higher mortality. This study aimed to determine the effect of different packing densities on the survival rate of broodstock shrimp during 12 hours of transportation. The experiment used four treatments with densities of 6, 8, 10, and 12 shrimp per bag, each with six replications. Observed parameters included temperature, dissolved oxygen (DO), and survival rate. The results showed that lower stocking density produced higher survival rates, with the best result obtained at 6 shrimp per bag. Water quality remained within acceptable limits, although oxygen levels decreased with increasing density. Therefore, proper stocking density is essential to maintain shrimp survival during transportation.  

Human activities, from household to industrial operations, generate liquid waste that poses a threat to the environment. Before discharge, liquid waste should be treated to ensure it is safe for release into the environment. This study aims to evaluate the effectiveness of a hybrid ozonation-adsorption method with varying contact times. This study collected leachate samples from the Rajabasa Landfill and used fly ash from the Tarahan Coal-Fired Power Plant as the adsorbent. First, the study used contact times of 20, 40, 60, and 80 minutes for ozonation. Subsequently, the 80-minute sample proceeded to the adsorption stage and was ultimately tested against six parameters. The measured parameters included COD, TSS, TDS, turbidity, UV254, and DO. The results showed that the 80-minute ozonation process significantly reduced TSS, TDS, and DO levels. However, the ozonation process still left intermediate compounds, which were subsequently removed by adsorption. Ultimately, the combination of the two processes yields good results, particularly for COD and UV254. This aligns with the theory that ozonation breaks down complex compounds while the adsorbent absorbs residual pollutants. This hybrid process achieves a 45.47% reduction in COD and an 87.83% reduction in UV254.

As an agricultural country, Indonesia is able to meet the demand for animal protein in the form of meat. Pigs are a potential business opportunity for some people because they are a promising livestock business. The study aims to determine the characteristics of livestock farmers and preferences for pig livestock in Tasinifu Village, Mutis District, North Central Timor Regency. This study was designed using a survey method. The technique for determining the research location used a purposive technique (intentionally) because Tasinifu Village is a village that has the highest pig population in Mutis District, TTU Regency. Data analysis was done using a quantitative descriptive method. The results of the study showed that livestock farmers were aged 18-40 years (31.67%), female farmers (55%), the highest level of education was elementary school (61.67%), the highest number of family dependents was 4-6 people (23.33%), livestock experience was 2-10 years (95%), dominant livestock ownership was 2-5 pigs with the majority of farmers working as farmers (97%), with land area owned 0-025/ha (66.67%). Pigs aged 5-7 months (41.67%), the most commonly raised breed is the Timor pig (75%), with female Calamine (58.33%), black skin (55%), and medium body weight (80%).

This study aims to evaluate the growth performance of KUB chickens fed with a combination of fermented agricultural waste, specifically Maggot BSF (Hermetia illucens) and Azolla microphylla. A total of 96 KUB chickens aged 30 days were used in a Completely Randomized Design (CRD) with four treatments and four replications. The treatments consisted of a basal diet substituted with the fermented waste combination at levels of 0% (P0), 5% (P1), 10% (P2), and 15% (P3). Parameters observed included feed consumption, body weight gain (BWG), and Feed Conversion Ratio (FCR). The results showed that increasing the level of waste substitution significantly affected feed consumption due to the bulky nature of the fiber, yet body weight gain remained stable across all treatments. The FCR values ranging from 3.21 to 3.25 indicated that the high-quality protein from Maggot BSF effectively compensated for the reduced feed intake. It is concluded that the substitution of fermented agricultural waste up to 15% (P3) is an optimal and efficient formulation to maintain the growth performance of KUB chickens.
