Abstract

Kappa-karagenan yang berasal dari rumput laut merah dikenal bersifat membentuk film yang sangat baik dan banyak digunakan sebagai bahan bioplastik. Formulasi kappa-karagenan dan pati limbah kulit singkong yang diperkuat dengan polivinil alkohol (PVA) berpotensi menghasilkan bioplastik dengan sifat fisikomekanik yang lebih optimal. Penelitian ini bertujuan untuk menentukan formula terbaik kappa-karagenan dan pati limbah kulit singkong sebagai bioplastik berdasarkan sifat fisikomekaniknya yang meliputi ketebalan, kuat tarik, elongasi, dan laju transmisi uap air dengan mengacu pada standar JIS Z 1707. Penelitian menggunakan rancangan acak kelompok lengkap (RAKL) dengan variasi rasio kappa-karagenan dan pati limbah kulit singkong. Hasil menunjukkan bahwa formula kappa-karagenan dan pati limbah kulit singkong secara signifikan memengaruhi seluruh sifat fisikomekanik bioplastik, kecuali densitas. Seluruh formula memenuhi standar JIS untuk kuat tarik dan elongasi. Formula yang menggunakan pati limbah kulit singkong dengan konsentrasi yang lebih tinggi secara signifikan memperbaiki sifat penghalang bioplastik dengan menurunkan laju transmisi uap air dan penyerapan air. Peningkatan konsentrasi pati meningkatkan elongasi film secara signifikan, tetapi mengurangi ketebalan, kuat tarik, dan modulus Young, serta menghasilkan biodegradasi yang lebih lambat. Formula terbaik diperoleh pada rasio 1% kappa-karagenan: 4% pati dengan ketebalan 0,35 mm, kuat tarik 1,14 MPa, elongasi 25,78%, dan laju transmisi uap air 18,47 g/m2/hari. Hasil ini menunjukkan bahwa formulasi kappa-karagenan dan pati limbah kulit singkong dapat menghasilkan bioplastik dengan sifat fisikomekanik yang memenuhi standar dan berpotensi mengurangi polusi plastik secara keberlanjutan di masa depan.

Abstract

This study aimed to determine the level of fisherman's participation in village development and the inhibiting factors of fisherman in participating in Malang Rapat Village, Bintan Regency, Riau Islands Province. This research was conducted in May-June using mixed research methods combining qualitative and quantitative research with a sequential exploratory research design, namely conducting qualitative research using a Likert scale first. By determining the sample that is 15% of the total population of 227 people. So the respondence is 34 people and the key informants are two people, namely the village head and head of BPD. Analysis of the data used is a qualitative descriptive analysis Likert scale with a gradation indicator of participation rate very high (4) high (3) moderate (2) and low (1). Then the sum of the scores for each answer will be divided by the number of respondents so that the average score for each question is obtained. The percentage of fisherman's participation in the development of Malang Rapat Village is by evaluating the three stages of participation, namely the planning stage by achieving an average score of 2.21 or with a percentage of 55.25% being in the high category, while at the implementation stage it reaches an average score of 2, 27 or with a percentage of 56.7% are in the high category, and at the supervision stage, an average score of 1.94 or a percentage of 48.5% is in the medium category. This is because the village of Malang Rapat has an effort to participate in every village activity by carrying out activities during the day when fishermen are not doing activities and establishing good communication with the community, especially fishermen. The inhibiting factor for fishermen in participating in every activity in village development is the awareness of the fishermen themselves in participating in activities.

Abstract

Pengudang Village is a tourist village located in Bintan Regency. The main tourist attraction in Pengudang Village is mangrove tourism. Mangrove tourism has its own charm for tourists, especially foreign tourists. Mangroves in Pengudang Village are very beautiful and their habitats are maintained, this cannot be separated from the participation of the community because their management is community-based. The importance of community participation in supporting the development of mangrove tourism, because effective development requires involvement (participation) from various parties (stakeholders), especially the community. The purpose of this research is to find out the driving factors and inhibiting factors for community participation in the development of mangrove tourism in Pengudang Village. The research uses qualitative research methods. Determination of the sample is 10% of the total

Abstract

Fisher households are coastal community groups that depend heavily on unpredictable marine catches, resulting in fluctuating household income. This condition encourages fishermen’s wives to participate in economic activities to help meet household needs. This study aimed to analyze the contribution of fishermen’s wives to household income in Kawal Urban Village, Bintan Regency. A quantitative descriptive method was employed, with purposive sampling used to select respondents. Data were analyzed by calculating total costs, total revenue, total income, and the percentage contribution of wives’ income to household income. The results showed that fishermen’s wives engaged in ten types of work: processed food seller, tailor, small-scale retailer, teacher, domestic helper, clothing reseller, fisher, religious teacher, babysitter, and food stall operator. Each occupation had different cost and income structures, resulting in varying contributions to household income. The highest average income was obtained from operating a food stall, while the lowest income came from low-capital service work. The percentage contribution of fishermen’s wives to household income ranged from 7.69% to 51.63%, with the highest contribution from the food stall business.
