The Role of Coastal Communities in the Rise of Islamic Civilization in Insular Southeast Asia
Authors: Jatmika Muhammad Indrawan
Published: November 2022

Islamic civilization in Insular Southeast Asia is believed to be brought and spread by Islamic Traders through the acculturation of Islamic culture in the coastal communities in the Southeast Asian Region. This paper is aiming to explain how coastal community have a role in the process of the Islamic civilization rise and how they become the dominant civilization in Insular Southeast Asia. The open- minded and egalitarian culture of the coastal communities gave the opportunity to the traders to have good process of acculturation that led to the development of Islamic Civilization in the region. Port cities on the coast became centers of cultural development as well as socio-political aspects of Muslims which then continued to suppress the center of power Hindu-Buddhist civilization which tends to be centralized and isolated in the interior. The development of Islamic culture in the coastal area also provides an opportunity for the development of new political figures and institutions who are then ready to take over the domination of culture after the collapse of the domination of the Hindu-Buddhist empire in Insular Southeast Asia.
Peradaban Islam di Asia Tenggara Kepulauan diyakini telah dibawa dan disebarkan oleh para Pedagang Islam melalui akulturasi budaya Islam yang dimulai pada masyarakat pesisir di Kawasan Asia Tenggara. Tulisan ini bertujuan untuk menjelaskan bagaimana masyarakat pesisir memiliki peran dalam proses kebangkitan peradaban Islam dan bagaimana mereka menjadi peradaban dominan di Asia Tenggara Kepulauan. Budaya masyarakat pesisir yang berpikiran terbuka dan egaliter memberikan peluang kepada para pedagang untuk memiliki proses akulturasi yang baik yang berujung pada berkembangnya Peradaban Islam di wilayah tersebut. Kota-kota pelabuhan di pesisir pantai menjadi pusat pengembangan budaya serta aspek sosial politik umat Islam yang kemudian terus menekan pusat kekuasaan peradaban Hindu-Budha yang cenderung terpusat dan terisolasi di pedalaman. Perkembangan budaya Islam di wilayah pesisir juga memberikan peluang bagi berkembangnya tokoh dan institusi politik baru yang kemudian siap untuk mengambil alih dominasi budaya pasca runtuhnya dominasi kerajaan Hindu-Budha di Asia Tenggara Kepulauan.

Authors: Andrukovich Petr
Published: November 2022

In the first part of this article [5], the structure of the model of the formation of groups of individuals from some of their random totality was described in detail. This part of this article provides an example of a calculation for identifying such groups, correcting the characteristics of individuals when they contact each other or when entering a group, as well as examples of the formation of images of groups. It is shown that even in a random set of individuals, sufficiently dense groups of individuals can arise in relation to the phenomena of the surrounding world known to them. It is also shown that taking into account the synergy of group members makes it possible to assess the differences between groups of individuals much more clearly. The model is implemented in Visual Basic within the framework of the AOM paradigm.

Malang Regency is an endemic area for cases of DHF (Dengue Hemorrhagic Fever) in East Java Province. One of the efforts to reduce the number of cases is to control the breeding of the Aedes aegypti mosquito which is the main vector. However, this will depend on the susceptibility status of Aedes aegypti to the insecticides used, one of which is malathion. This study aims to determine the susceptibility status of Aedes aegypti mosquitoes to malathion insecticides in Malang Regency in the southern part. This descriptive observational study used adult Aedes aegypti mosquitoes obtained from the landing collection of larvae from three sub-districts in Malang Regency in the southern part (Kepanjen, Gondanglegi, and Bantur). The location selection was done by simple random sampling technique. The larvae of the Aedes aegypti mosquito were then reared in the Chemistry Laboratory, University of Muhammadiyah Malang. Adult mosquitoes with stomach conditions full of sugar were then tested using the susceptibility test which refers to WHO standards. The results showed that the mortality rate of the tested mosquitoes in the Districts of Kepanjen, Gondanglegi, and Bantur, respectively, reached 98%, 93%, and 96%. This shows that the Aedes aegypti mosquitoes in the three locations are classified as tolerant to the insecticide malathion by 0.8%. Thus, it can be concluded that the insecticide malathion is still effectively used as vector control for DHF (Dengue Hemorrhagic Fever) in Malang Regency.

This study aims to determine the carrying capacity of the protected function and the carrying capacity of land based on the ratio of land availability and demand for land in Sumbawa Regency. The research method uses a quantitative descriptive approach with an analysis of the carrying capacity of the protected function and the analysis of the carrying capacity of the land is carried out using an approach to land availability and land requirements. The results showed that the carrying capacity of the protected function of 24 sub-districts in Sumbawa Regency obtained 4 sub-districts (16.7%) in very good category, 6 sub-districts (25%) in good category, 2 sub-districts (8.3%) in moderate category, 3 sub-districts ( 12.5%) in the damaged category, and 9 sub-districts (37.5%) in the very damaged category. The sub-districts that fall into the category of severely damaged environmental carrying capacity include: Labuhan Badas, North Moyo, Moyo Hulu, Ropang, Lape, Lopok, Labangka, Maronge, and Tarano sub-districts with an environmental carrying capacity value below 0.20. The sub-districts in Sumbawa Regency that have a deficit land carrying capacity status (25%), include: Alas, Utan, Buer, Rhee, Batulanteh, Sumbawa, and Unterwilis sub-districts. Judging from the ratio of land availability and land demand, it is known that Alas, Sumbawa, and Labuhan Badas sub-districts have the smallest ratio, meaning that the level of land demand in the three sub-districts is high compared to land availability, so that the existing land is no longer able to support the needs of the population.

Moon Orchid (Phalaenopsis sp.) is an ornamental plant that has attractive flowers and has economic value. Cultivation can be optimized by modifying the MS medium. The addition of natural growth regulators with the right concentration can support the success of tissue culture and can also reduce costs. This study aims to determine the addition of water hyacinth root extract in the first subculture stage of the moon orchid. This study used a factorial completely randomized design with 4 treatments and 6 replications, namely: MS0 (MS medium), MS1 (MS medium + 10% water hyacinth root extract), MS2 (MS media + 15% water hyacinth root extract), and MS3 (MS medium + 20% water hyacinth root extract). Observation variables included: number of leaves, number of roots, and plantlet height. The results showed that there was an interaction between MS media and the addition of water hyacinth root extract in the first subculture stage of the moon orchid on MS3 media (MS media + 20% water hyacinth root extract) indicating optimal results on the three parameters, namely: number of leaves 5, 2 strands, the number of roots 5.8 fruit, and plantlet height 2.3 cm.

The study was conducted to determine the effect of several compositions of growth regulators (PGR) on germination and shoot initiation of dates (Phoenix dactylifera L.) in vitro. The study consisted of 2 experimental stages. The first phase of the study was aimed to determine the effect of the addition of Gibberellin PGR on the length of time the sprouts appeared, the number of explants that germinated, and the length of the sprouts produced. The second stage of the research was to determine the combination of PGR Indhol Acetic Acid (IAA) and Benzyl Amino Purine (BAP) which was able to initiate the emergence of shoots in the hypocotyl of dates. The study was designed using a completely randomized design (CRD). The first experiment consisted of 3 media treatments, namely: agar without additional ZPT (GA0); agar medium with 50 ppm GA (GA1); and agar medium with 100 ppm GA (GA2). Each media treatment consisted of 5 seeds and was repeated 3 times. The second stage of the experiment was designed in a completely randomized design with 5 media treatments, namely: P0 (MS medium without PGR); P1 (MS + 1 ppm IAA + 1 ppm BAP); P2 (MS + 2 ppm IAA + 1 ppm BAP); P3 (MS + 3 ppm IAA + 1 ppm BAP); P4 (MS + 1 ppm IAA + 2 ppm BAP); and P5 (MS + 1 ppm IAA + 3 ppm BAP). Each treatment consisted of 5 explants and repeated 3 times. Parameter observation data were analyzed by Analysis of Variance (ANOVA) and if significant results were obtained, continued with the Least Significant Difference (BNT) further test. The results of the first experimental data analysis showed that the treatment with 50 ppm GA3 significantly shortened the time of emergence of sprouts to 10 days and the number of explants that germinated on average was 4.5 explants. The results of observations and data analysis in the second experiment showed that the combination of IAA and BAP ZPT were significantly able to induce shoot formation on P4 and P5 media, which were 2.83 and 1.3 explants that formed shoots, respectively. Treatment with P4 was able to significantly increase the number of shoots produced by an average of 2.63 shoots per explant.

This study aims to: 1) obtain growth regulators that are easy to obtain at low prices, because synthetic growth regulators are relatively expensive for novice researchers and are very difficult to obtain; and 2) to find out whether household waste can be used as a plant growth regulator in vitro which has been widely used and has been successful conventionally in several types of plants. The method used in this study was experimental, using a completely randomized design (CRD) with three replications. The media used was MS media by adding growth regulators from household waste with a concentration of (0-3) mg/L. The parameters in this study were the number of shoots and roots. The data obtained were then analyzed qualitatively, because the resulting data was not normal and not homogeneous. The results showed that the highest number of shoots was at a concentration of 2 mg/L organic waste growth regulator, with 5 shoots and 15.7 roots, with 8 days after planting on chrysanthemum growing media.
