Abstract

Genealogy as a system is generally used to preserve a tradition, culture, thought, science, or power. However, in the Raudhatul Muttaqin Mosque, Kotaraja East Lombok and Al-Bayani Mosque, Gondang, North Lombok, this system is actually used to determine the imam, which in Islam and the government there are no rules regarding the obligatory prayer imam from certain descendants. The purpose of the research is to identify how the descendants of Sheikh H. L. Abdurrahman and Amiq Sahabuddin communicate with the community in implementing the genealogical system of mosque imam in Kotaraja and Gondang. The research method used is a qualitative type of a case study and data were collected through observation, documentation, and interviews with the generations of Shaykh H. L. Abdurrahman and Amiq Sahabuddin as mosque imam, community leaders, and villagers. The study concluded that the main actors of persuasion to the community are the descendants of the imam who are supported by the power of the message, media, argumentation, psychological appeal, credibility, and legitimacy of the community. The persuasion process of the descendants of the imam displays convincing expressions and contains various values, both religious, customary, social, and educational values, so that the community can accept it well.

Abstract

This research aims to describe the practice of buying and selling land carried out by sellers to other parties, even though the land was previously the object of sale and purchase with previous parties in the PPJB. The research methodology employed is qualitative research with a case study approach. The findings of this research indicate that land sale and purchase transactions (mutsman) conducted by the seller (al-ba'i) with buyers (al-Musytari) still within the PPJB with other parties constitute a form of buying and selling that does not align with the pillars and conditions of transactions in Sharia economics. The object of sale and purchase (mutsman) that is resold by the seller (al-ba'i) must be owned outright, or if not owned, permission must be obtained from the rightful owner. The resale of goods (mutsman) previously purchased by another individual is prohibited for the seller (al-ba'i) to the buyer (al-Musytari). Consequently, the sale and purchase are deemed invalid.

Abstract

Human smuggling is a form of transnational crime involving individuals or groups to facilitate the movement of illegal immigrants across national borders, either in an organized or unorganized manner. Immigrants who are often victims of armed conflict or war use land and sea routes to seek protection in their destination countries. The Strait of Malacca as one of the most important international shipping lanes in the world is an area that is vulnerable to being used as a route for human smuggling. Koarmada I has a strategic role in maintaining the security of the Strait of Malacca, especially in combating human smuggling. The strategies used include deploying troops at sea, coordinated patrols with neighbouring countries, and Indonesian Navy diplomacy. Obstacles in implementing this strategy include the very large operational area, limited intelligence information, and the absence of special standard operating procedures for handling illegal immigrants at sea. This study uses a qualitative methodology with the Nvivo application with the aim of analysing the strategy for handling human smuggling in the Strait of Malacca implemented by Koarmada I. The results of the study are expected to provide relevant recommendations for the development of more effective strategies in efforts to maintain national security. This approach is also expected to improve cooperation between the Indonesian Navy and relevant stakeholders to face the challenges of human smuggling in the Malacca Strait region.

Abstract

The carrageenan production process from Kappaphycus alvarezii seaweed produces solid waste of 60%-70% w/w, primarily composed of cellulose, which can be used for bioplastic films. This research aims to determine the effect of glycerol plasticizer addition on the characteristics of K. alvarezii waste-based bioplastics. Bioplastics were made by mixing 50 g of wet waste with 90 mL of distilled water, homogenized at 70°C for 30 minutes. Glycerol (0%, 1%, 2%, 3%, 4%) was added, with water to a total volume of 150 mL, and homogenized again for 30 minutes. The solution was poured into a polypropylene mold and dried at 60°C for 24 hours. Results showed glycerol increased transparency and elongation but reduced tensile strength and water resistance. The addition of 1% glycerol produced bioplastics with the best characteristics, meeting Japanese Industrial Standards. FTIR and SEM showed similar bioplastic properties across treatments. This research indicates that K. alvarezii carrageenan extraction waste is promising for packaging material and bioplastic production.  Proses produksi karagenan dari rumput laut Kappaphycus alvarezii menghasilkan limbah padat sebesar 60%-70% w/w, terutama terdiri dari selulosa yang dapat digunakan untuk film bioplastik. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan plastisizer gliserol terhadap karakteristik bioplastik limbah K. alvarezii. Bioplastik dibuat dengan mencampurkan 50 g limbah basah dengan 90 mL akuades, dihomogenkan pada suhu 70°C selama 30 menit. Gliserol (0%, 1%, 2%, 3%, 4%) ditambahkan hingga volume 150 mL, dihomogenkan kembali selama 30 menit. Larutan dituang dalam cetakan polipropilena dan dikeringkan pada suhu 60°C selama 24 jam. Hasil penelitian menunjukkan gliserol meningkatkan transparansi dan elongasi, tetapi mengurangi kuat tarik dan ketahanan air. Penambahan 1% gliserol menghasilkan bioplastik dengan karakteristik terbaik, memenuhi Japanese Industrial Standard. FTIR dan SEM menunjukkan sifat bioplastik yang serupa pada semua perlakuan. Penelitian ini menunjukkan bahwa limbah ekstraksi karagenan K. alvarezii menjanjikan sebagai bahan kemasan dan produksi bioplastik.

Abstract

Synthetic plastic is commonly used daily, but its non-biodegradable nature poses a significant environmental threat. Therefore, it is urgent to explore sustainable alternatives such as bioplastics. Alginate, a polysaccharide, is a promising raw material for bioplastics. However, its poor elasticity characteristic necessitates the addition of other polysaccharides, such as carrageenan, to improve bioplastics' mechanical properties. This research aims to determine the characteristics (physical and mechanical properties) of bioplastics made from a mixture of alginate and kappa-carrageenan. The laboratory experimental methods were applied with a completely randomized design. The treatments are mixtures of alginate and k-carrageenan in the following ratios: 10:0 (A10K0), 8:2 (A8K2), 6:4 (A6K4), 4:6 (A4K6), 2:8 (A2K8), 0:10 (A0K10). The characteristics of bioplastic films measured were thickness, water resistance, tensile strength, elongation, and appearance. The optimal bioplastic formulation (4:6 ratio of k-carrageenan to alginate) exhibited a film thickness of 138.3 µm, 16.6% biodegradability, tensile strength of 22.965 N/mm², and 2.73% elongation. The scanning electron microscope showed that the surface structure of bioplastic A4K6 made fromthe ratios of k-carrageenan and alginate of 4:6 had fewer structure cracks and more surface smoothness.

Abstract

Salah satu faktor penurunan produktivitas udang disebabkan oleh faktor lingkungan, termasuk salinitas dan kualitas pakan, sehingga perlu ditingkatkan. Tujuan penelitian ini untuk mengetahui pengaruh pemberian Artemia yang diperkaya alginat terhadap tingkat kelangsungan hidup, pertumbuhan dan ketahanan terhadap stres salinitas pada Post-Larva (PL)1 Litopenaeus vannamei. Pengkayaan Artemia dilakukan dengan proses perendaman selama satu jam. Metode yang digunakan pada penelitian ini adalah Rancangan Acak Kelompok, dengan Kontrol (tanpa pengkayaan alginat) dan 3 perlakuan (pengkayaan Artemia sebanyak 10 ekor/mL/hari dengan alginat pada dosis 0 (kontrol), 400, 600, 800 ppm). Setiap perlakuan diulang sebanyak tiga kali. Pemeliharaan dengan pemberian pakan pengkayaan Artemia dilakukan selama 14 hari. Pertumbuhan panjang mutlak tertinggi diperoleh perlakuan yang diberi Artemia yang diperkaya alginat 600 ppm. Pertumbuhan mutlak berat diperoleh dari perlakuan Artemia dengan pengkayaan alginat 600 dan 800 ppm. Ketahanan stres salinitas tertinggi dengan kematian terlama diperoleh pada perlakuan yang diberi Artemia dengan pengkayaan alginat 400 ppm. Pemberian Artemia yang diperkaya alginat mampu meningkatkan pertumbuhan dan ketahanan terhadap stres salinitas PL L. vannamei, namun tidak menunjukan pengaruh terhadap tingkat kelangsungan hidup.

Abstract

Logam besi (Fe) merupakan logam berat essensial yang dibutuhkan oleh makhluk hidup termasuk manusia dalam jumlah sedikit.  Jika jumlahnya melebihi batas ambang dapat menimbulkan efek racun karena bersifat karsinogenik. Salah satu upaya mengurangi kadar logam Fe pada daging kerang tersebut dapat dilakukan dengan memanfaatkan kitosan atau turunan kitosan yaitu karboksimetil kitosan (KMK) sebagai adsorben. Penelitian ini bertujuan mengetahui pengaruh variasi konsentrasi KMK dan kitosan terhadap kapasitas dan daya adsorpsi, serta konsentrasi terbaik dalam menurunkan kandungan logam berat Fe pada jaringan lunak kerang hijau. Metode penelitian secara eksperimental laboratoris. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktor. Faktor pertama yaitu sumber kitosan yang digunakan yaitu kitosan dan karboksimetil kitosan (KMK) dan faktor kedua yaitu variasi konsentrasi yaitu kontrol (0%); 0,5%; 1%; 1,5% dan masing-masing perlakuan dengan 3 ulangan. Konsentrasi logam berat Fe awal pada kerang hijau sebesar 13,17 mg/kg. Hasil penelitian menunjukkan adanya pengaruh variasi konsentrasi kitosan dan KMK terhadap kapasitas dan daya adsorpsi logam berat Fe pada jaringan lunak kerang hijau. Konsentrasi terbaik pada kitosan 1,5% dapat menurunkan logam berat Fe menjadi 2,43 mg/kg dengan kapasitas adsorpsi sebesar 0,72 mg/g dan daya serap 81,56%, sedangkan KMK 1,5% dapat menurunkan logam berat Fe menjadi 3,68 mg/kg dengan kapasitas adsorpsi 0,63 mg/g dan daya serap sebesar 72,04%.  Fe is an essential heavy metal needed by humans in small amounts, if the amount exceeds the threshold, it can cause toxic effects because it is carcinogenic. To reduce the metal content of Fe in mussel meat, it can be done by utilizing chitosan or chitosan derivatives, namely carboxymethyl chitosan (KMK) as an adsorbent. This study aims to determine the effect of variations in the concentration of KMK and chitosan on the adsorption capacity and power as well as the best concentration in reducing the heavy metal content of Fe in the soft tissue of green mussels. The research method is experimental laboratory. The research design used a completely randomized design (CRD) with 2 factors. The first factor is the source of chitosan used, namely chitosan and carboxymethyl chitosan (KMK) and the second factor is the variation in concentration used, namely control (0%), 0.5%, 1%, and 1.5% and each treatment 3 repetition. The initial heavy metal concentration of Fe in green mussels was 13.17 mg/kg. The results showed that there was an effect of variations in the concentration of chitosan and KMK on the capacity and adsorption ability of heavy metal Fe in green mussel meat. The best concentration of 1.5% chitosan can reduce heavy metal Fe to 2,43 mg/kg with adsorption capacity of 0.72 mg/g and absorption ability of 81.56%. Meanwhile, KMK 1.5% can reduce heavy metal Fe to 3.68 mg/kg with adsorption capacity of 0.63 mg/g and absorption ability of 72.04%.

Abstract

The purpose of this study was to describe the problem of unemployment and work obligations according to al-Syaibani, using qualitative research methods and a literature study approach. The results of the study showed that the total unemployment rate in the period 2014 to 2018 was still fluctuating, and the average unemployment rate in that period of 100 Indonesians is 6 people who were unemployed. Meanwhile, according to Al-Syaibani, work was obligatory. Al-Syaibani also argued that everyone needed labor from others based on their expertise. The distribution of work was an economic object that had two aspects simultaneously, namely the economic aspect and the religious aspect. The problem of unemployment was an economic problem, so that all elements, both the government and the community, needed synergy in reducing the unemployment rate in Indonesia.
