Medicinal plants are plants whose leaves, stems and roots can be used as medicine. Some of these medicinal plants are used in traditional or alternative medicine in local communities. Apart from that, medicinal plants also have the advantage that they do not cause side effects and can be treated by family members themselves. The successful use of medicinal plants is greatly influenced by public knowledge about the benefits of each type of medicinal plant, especially medicinal plants that have been studied empirically. Research with the title Inventory of Medicinal Plants in the Babakan Siliawangi City Forest Area on June 12 2024, with this research method aims to determine the diversity of types of medicinal plants and to determine the potential of these medicinal plants for the surrounding community. The results of this research were 10 types of medicinal plants, including: Binahong, Yellow Bamboo, Jengkol, Matoa, Forest Tea, Forest Betel, Japanese Papaya, Sausage Tree, Butterfly Tree, Simpur Tree. The most widely used medicinal plant organ is the root, bark, flowers and leaves.
 
 

This study aims to analyze the effect of feed supplements on the health and growth of beef cattle. The method used is a literature review, examining various relevant sources related to livestock feed and supplements. The results show that the addition of protein in feed increases the average daily gain (ADG) of cattle by 1.0-1.2 kg/day compared to cattle without supplements (0.7 kg/day). Feed supplements also proved to improve feed conversion efficiency by up to 20-25% and reduce feed costs when combined with local feed. Additionally, the provision of minerals and vitamins such as vitamin E and selenium contributes to improving cattle immunity and reproductive health. The implementation of good livestock health management, including routine administration of vitamins and deworming, is key to enhancing the productivity and health of beef cattle.

The Ritel business in Indonesia is growing and increasing every year because it is considered a promising investment with great potential for significant profits. This study aims to understand and evaluate the layout of Retail Lestari's business. The method used in analyzing the data is the Activity Relationship Chart (ARC) and Total Closeness Rating (TCR) method. Based on the results of the Activity Relationship Chart (ARC) analysis of Ritel Lestari, the facility prioritized for first construction is the cashier, as the cashier has the highest Total Closeness Rating (TCR) value of 76. Therefore, to facilitate the operational process, the placement of other facilities is prioritized based on their highest relationship values to the warehouse to be in close proximity.

This study investigated the effect of genetic quality of local North Sumatra cattle on fattening efficiency. PCR and RFLP-based genetic analyses and fattening efficiency measurements through average daily growth (ADG) and feed conversion (FCR) were used. local cattle from Deli Serdang, Langkat, and Simalungun were used. The study showed that feed management involving the use of concentrate and high-quality forage can improve cattle fattening efficiency, and the IGF-1 gene plays a significant role in cattle growth. A strong correlation between fattening efficiency and genetic quality (r = 0.85) indicates the importance of genetic selection to improve productive local cattle. Based on these findings, it is recommended to implement molecular marker-based genetic selection programmes and improve feed management by diversifying local feed sources. In addition, it is necessary to improve farmer training on more efficient husbandry methods. This research provides policy suggestions that can be implemented to support the curiosity of the livestock industry in North Sumatra and improve the efficiency of local cattle production.

Rice holds a significant place as a staple food in Indonesia, with its life cycle spanning between 3 to 6 months, depending on the specific variety. An essential part of preserving the quality of rice grains is the drying process. This research aims to investigate how drying affects the quality of rice during this crucial stage. The findings of this study are not only intended to build upon previous research but also to serve as valuable guidance for farmers in making informed decisions about the drying process, ultimately ensuring optimal quality in their harvested grains. This study employed an experimental approach using a completely randomized design, wherein treatments were assigned randomly across all experimental units. The results indicated that the duration of drying significantly impacts the quality of rice grains. It was found that optimal drying occurs over a period of 3 to 4 days under sunlight on a tarpaulin base, which can be effectively used as a benchmark for assessing the quality characteristics of milled upland rice.

Study was to emit various strategies to develop buffalo cattle in a semi-intensive rearing system at BPTU HPT Siborongborong. Primary data, collected through observation, focus group discussion (FGD), and secondary data, collected through relevant reports and literature. Development potential, challenges and opportunities were identified using desirability evaluation, descriptive analysis and SWOT. The results show that the semi-intensive system implemented has improved animal productivity, with adult buffaloes averaging 500 kilograms in weight and 0.7 kilograms in daily growth. The system also offers significant economic benefits, with an average net profit of IDR 800,000 for each head each month. However, a lack of protected human resources and seasonal forage shortages remain constraints. Feed diversification, farmer training and analysing the use of advanced technology are the plans made based on SWOT. The Siborongborong semi-intensive system has a great opportunity to become an example of effective and sustainable buffalo management in Indonesia.

Physical modification of starch using microwave heat treatment (MHT) technology serves as an efficient and environmentally friendly alternative to enhance the functional properties of starch without chemical additives. This article aims to examine the influence of microwave power and heating duration on the swelling power and solubility of various starch types, including tapioca, taro, sago, and lotus rhizome. A review of four studies revealed that power and time parameters significantly affect the crystalline structure of starch granules, resulting in either enhancement or reduction of their functional properties. High power or prolonged heating may decrease swelling power due to crystal restructuring and granule disruption, while solubility increases as a result of amylose and amylopectin degradation. MHT has proven to accelerate the heating process in a volumetric and efficient manner, improving water absorption capacity and viscosity. Despite its drawback of uneven heat distribution, this method remains relevant as a physical modification technique aligned with green processing principles in the food industry.

Harvesting is a crucial stage in the palm oil production process that impacts the efficiency and productivity of the plantation. Choosing the right harvesting method can increase the effectiveness of time and labor. This study compares harvesting efficiency using manual and mechanized methods by measuring the duration of fruit harvest and transportation time to the collection point (TPH). This study was conducted in November–December 2024 at PT. Kencana Sawit Indonesia, located in Talao Sungai Kunyit, South Solok, West Sumatra. The equipment used included stationery, a stopwatch, and data related to working time and harvest results. Data were collected through direct observation. The analysis was carried out using the t-student statistical test to evaluate the difference in working time between the manual and mechanized methods. The results showed that harvesting with mechanization was more efficient than the manual method. The difference in harvest time reached 12 seconds per bunch with a P value of 0.0002, while the transportation time to the TPH was 23.48 minutes faster per ton with a P value <0.0001. Monthly production with mechanization averaged 48.69 tons, while the manual method only produced 38.13 tons per month. Thus, the use of mechanized harvesting methods has proven to be faster in the harvesting process, fruit transportation, and increasing monthly production results. The implementation of mechanization can be a strategic step to increase operational efficiency and productivity of oil palm plantations.
