Abstract

The study was conducted in three different ecosystems: mamar (a typical local ecosystem close to water catchment areas), farm, and coastal ecosystems. In each ecosystem, soil samples were taken from the rhizosphere of five different plants to investigate the occurrence of PSM, molecularly identify the potential isolates, and evaluate their ability to increase soil phosphorus (P) availability and mungbean yield. The highest population of phosphate-solubilizing bacteria (PSB) was found in the mamar ecosystem. Phosphate-solubilizing fungi were only found in the farm and coastal ecosystems, with low populations, and restricted to the rhizosphere of a few plants. The number of PSB isolates was higher in the coastal ecosystem, followed by the farm and mamar ecosystems. The phosphate solubilizing index of the isolate was quite high, ranging from 210 to 300. One isolate from the five molecularly selected isolates from Kupang regency was identified as Aspergillus sp. (cassava rhizosphere origin), one isolate from the farm ecosystem (Moringa rhizosphere origin), and three isolates from the coastal ecosystem (Jatropha gossypiifolioa, Scheichera oleosa and Calotropis gigantea L. rhizosphere origin) were all identified as Pseudomonas sp. Two selected isolates from a previous study in Timor Tengah Selatan regency, collected from the mamar ecosystem (bamboo and Leuchaena leucocephala rhizosphere), were both identified as Acinetobacter baumannii. Inoculation of PSB resulted in higher available soil P compared to the uninoculated treatment. PSB inoculation also provided higher tissue P than the uninoculated treatment. PSB from coastal areas gave the highest pod weight and seed weight compared to other inoculation treatments.

Abstract

The main issue faced by Kelompok Tani Pelangi (Pelangi Farmer Group) in lowland rice cultivation is the frequent attack of pests and diseases, such as brown planthopper, rice stem borer, and rice bug. To control these pests, most farmers still rely heavily on synthetic pesticides without considering their impacts on beneficial organisms and the environment. This Community Partnership Programme aims to enhance farmers' capacity in environmentally friendly pest management through educational outreach and field-based practices. The methods employed in this programme include educational sessions, hands-on field demonstrations, interactive discussions, and questionnaire-based evaluations. The material delivered covered the identification of pests and diseases in rice, the introduction and implementation of eco-friendly pest control strategies, correct use of synthetic pesticides, and the role and function of refugia plants in conserving natural enemies. Evaluation results indicated a positive impact on the knowledge of farmer group members: 98% were able to identify pest types and their symptoms, 67% recognised predators in the field, 50% understood the principles of appropriate pesticide use, 60% comprehended the negative impacts of pesticides, and 44% recognised the benefits of refugia plants in the rice agroecosystem. The active participation of farmers during discussions and practical sessions reflects a behavioural shift towards sustainable farming practices. This Community Partnership Programme (PKM) has proven effective in improving ecological awareness and technical skills among members of Kelompok Tani Pelangi and is recommended as a model for empowering farmers in surrounding areas through the Integrated Pest Management (IPM) approach.

Abstract

Penelitian ini bertujuan untuk menganalisis dinamika sistem sosial budaya dan dampaknya terhadap integrasi bangsa di Indonesia. Dalam masyarakat yang multikultural, dinamika sosial budaya berperan penting dalam memperkuat atau melemahkan integrasi bangsa. Melalui metode penelitian literatur, berbagai aspek sistem sosial budaya yang berkontribusi terhadap integrasi bangsa akan dikaji dengan fokus pada pengaruh faktor-faktor seperti globalisasi, modernisasi dan teknologi terhadap kehidupan sosial masyarakat. Hasil penelitian menunjukkan bahwa dinamika sosial budaya yang dikelola dengan baik dapat memperkaya identitas nasional, memperkuat toleransi dan membangun semangat persatuan. Sebaliknya, jika tidak dikelola dengan bijak, dinamika ini berpotensi menimbulkan konflik, pergeseran nilai budaya, dan disintegrasi sosial. Oleh karena itu, penting untuk terus memperkuat pendidikan nilai kebangsaan, pelestarian budaya lokal, serta penguatan komunikasi antar kelompok sosial agar keberagaman tidak menjadi sumber perpecahan melainkan kekuatan pemersatu bangsa.This study aims to analyze the dynamics of the socio-cultural system and its impact on national integration in Indonesia. In a multicultural society, socio-cultural dynamics play an important role in strengthening or weakening national integration. Through the literature research method, various aspects of the socio-cultural system that contribute to national integration will be studied with a focus on the influence of factors such as globalization, modernization and technology on the social life of society. The results of the study indicate that well-managed socio-cultural dynamics can enrich national identity, strengthen tolerance and build a spirit of unity. Conversely, if not managed wisely, these dynamics have the potential to cause conflict, shifts in cultural values, and social disintegration. Therefore, it is important to continue to strengthen national value education, preserve local culture, and strengthen communication between social groups so that diversity does not become a source of division but a unifying force for the nation.

Abstract

This paper compares the magnetic, electrical, and mechanical characteristics of two permanent magnet generator topologies: single-gap axial flux and single-gap inner rotor radial flux. The study aims to identify how the key parameters fluctuate at each power capacity and investigate the trends in their values as power changes. The power capacities observed are 300 W, 600 W, 900 W, 1200 W, and 1500 W. Simulations used with the help of Ansys Maxwell software to obtain: i) magnetic characteristics without load, including air gap flux density, flux linkage, and induced voltage, ii) electrical performance, consisting of armature current, terminal voltage, voltage regulation, total harmonic distortion, core loss and output power, and iii) mechanical performance, including shaft torque and cogging torque. The last step compares the power density of both topologies. The simulation results show that the axial flux permanent magnet generator (AFPMG) has better air gap flux density, voltage regulation, total harmonic distortion (THD), efficiency, electromagnetic torque, and power density characteristics. Meanwhile, the radial flux permanent magnet generator (RFPMG) is superior in induced voltage and output power. These results conclude that, in general, AFPMG is exceptional from a technical point of view and is more economical when applied to hydro or wind energy systems.

Abstract

The study area is located in Mootilango Village Anggrek Sub-district, North Gorontalo Regency, Gorontalo Province. Geographically, the study area is located at coordinates 0° 46' 0" - 0° 46' 45” LU and 122° 48' 0” - 122° 48' 45" BT with an area of about 3.7 km². The purpose of this study was to determine the characteristics of tuff rocks through petrological, petrographic and geochemical analysis in the laboratory. The results of petrological identification show that the rock types are coarse tuff, fine tuff and pyroclastic breccia. The results of petrographic analysis show that the tuff in this area belongs to Vitric tuff according to the classification of Schmid (1981). The results of geochemical analysis show that the tuff in the study area belongs to the basalt-andesite type transition rock group according to the classification of Le Bas et al. (1986). Two classification approaches were used in the analysis to determine the magma series of the rock, namely according to Irvine and Baragar (1971), which shows that the rock belongs to the tholeiitic magma series.
