Abstract

The northern coast of Bali possesses significant natural resource potential, particularly in Desa Musi, Kecamatan Gerokgak, which serves as a site for fish and seaweed cultivation managed by the local communities. However, some of these aquaculture activities lack adequate wastewater management systems. This study aimed to evaluate the water quality along the coast of Desa Musi, Kecamatan Gerokgak, Bali. A quantitative descriptive approach was employed, with purposive sampling conducted at selected locations along the coastal area. The water quality parameters assessed included salinity, pH, temperature, phosphate, ammonia, lead, and cadmium concentrations. The findings revealed that the coastal waters of Desa Musi generally support marine biota. However, the concentrations of lead and cadmium exceed the threshold values stipulated by Kep-51/MenKLH/2004. These results underscore the need for regular water quality management and monitoring to ensure environmental sustainability and support the livelihoods of the local community.Keywords: Coastal ecosystems, environmental monitoring, heavy metals.

Abstract

Sidat merupakan ikan katadromus yaitu ikan yang memiliki fase dewasa berada di sungai atau danau tetapi setelah matang gonad akan beruaya ke laut lepas dan memijah disana. Perjalanan yang jauh dan membutuhkan waktu yang lama dengan berbagai rintangan. Sidat memiliki gizi yang tinggi yang kaya akan permintaan akan ekspor. Permintaan yang tinggi juga berdasal dari budidaya pembesaran sidat yang meningkatkan penangkapan sidat akan benih dari alam. Tujuan penelitian ini adalah memberikan gambaran karateristik biologi dan penangkapan ikan sidat di beberapa sungai di Kota Bengkulu. Karateristik yang dimaksud adalah distribusi panjang, hubungan panjang berat, nisbah kelamin, gambaran gonad ikan sidat, indeks kematangan gonad dan indeks hati. Hasil penelitian menunjukan distribusi panjang ikan sidat terbesar berasal dari Sungai Muara Jenggalu dan yang terkecil dari Sungai Hitam. Pola pertumbuhan berbeda tiap lokasi sungai yaitu allometrik negatif untuk ikan yang berasal dari Sungai Hitam dan Muara Bangkahulu. Pola pertumbuhan isometrik didapatkan dari lokasi Muara Jenggalu. Nisbah kelamin yang ada didominasi oleh ikan yang intersex. Indeks kematangan gonad dan indeks hati menunjukan trend kenaikan berat hati mengikuti tren pertumbuhan panjang.

Abstract

Seaweed commodities are one of the products in the fisheries and marine sector that has the potential to be developed. One type is sea grape or commonly known as Caulerna lentillifera which is very widely spread in waters throughout Indonesia. This research method is descriptive quantitative, this research was conducted to determine the heavy metal content in natural sea grapes and cultivated sea grapes. The research procedure consisted of pre-research process to observation and checking of heavy metal content. The results of research on heavy metal content of cultivated sea grapes get good results, while for nature there are levels of heavy metals Pb so it can be said that it is not very good. The results of measuring the length of ramuli in the first week was 3.3 cm, the second week was 4.4 cm then increased in length in the third week to 5.8 cm, and ended in the fourth week with an increase in length of 6.9 cm. The results of the calculation of the number of ramuli in week 1 showed that the average number of ramuli was 12, the average number of ramuli in the first week increased to 14 in the second week and increased in the third week to 17 then ended in the fourth week with an average of 19 ramuli. The quality of water used in the cultivation of sea grapes in Musi Village and natural sea grapes is still in normal status.

Abstract

Peningkatan produksi Oreochromis niloticus dalam sistem budidaya intensif sering terhambat oleh penurunan kualitas air akibat akumulasi limbah organik. Penelitian ini bertujuan mengevaluasi efektivitas pakan bersinbiotik, kombinasi Probiotik EM4 dan Prebiotik tepung ubi jalar (Ipomoea batatas L.), dalam memitigasi senyawa nitrogen toksik dan memperbaiki ekosistem perairan. Penelitian eksperimental dengan pendekatan deskriptif selama 30 hari, ini membandingkan tiga perlakuan: Kontrol (tanpa sinbiotik), Dosis A (Probiotik 1% + Prebiotik 2%), dan Dosis B (Probiotik 2% + Prebiotik 1,5%). Parameter yang diukur meliputi amonia, nitrit, nitrat, dan komposisi plankton. Hasil menunjukkan perlakuan sinbiotik secara signifikan menjaga kualitas air. Perlakuan Kontrol mengalami akumulasi nitrit sangat tinggi, mencapai 35,67 mg/L, yang berakibat pada mortalitas. Sebaliknya, Dosis A dan B berhasil mengendalikan kadar amonia dan nitrit, menunjukkan peningkatan efisiensi siklus nitrifikasi. Dosis A (1% Probiotik, 2% Prebiotik) terbukti paling optimal, memicu pertumbuhan masif plankton (biofilter alami) dengan kelimpahan tertinggi (4,97 x 106 ind/mL) di akhir penelitian. Simpulan, pemberian pakan bersinbiotik, khususnya Dosis A, merupakan strategi manajemen kualitas air yang efektif dalam menciptakan lingkungan budidaya yang seimbang.

Abstract

The purpose of this research was to identify heavy metals in Jembrana waters and analyze water quality to determine water fertility. This study used direct observation and quantitative descriptive. Primary production, biological chemical physical parameters, and heavy metal data were collected in this study. The results showed that Jembrana waters had the highest primary productivity value of 1051.01 mgC/m3/day and the lowest value of 112.61 mgC/m3/day. Water quality in Jembrana is considered quite good. The results of this study showed that the water conditions at the observation site remained stable and within the tolerance limits for marine biota. This is due to the fact that during the sampling period, there was no significant activity from fishermen and local residents. Observations of heavy metals lead and cadmium at the study site showed that some stations exhibited values that exceeded the threshold, but these values were still acceptable for the waters. The heavy metal levels at the stations exceeded the threshold due to sewage effluents from companies and ships in the local harbor.

Abstract

Geographically, Buleleng Regency in North Bali has high potential coastal resources, with a coastline length reaching 157.05 km. Bondalem Village is in Tejakula District, Buleleng Regency, in the northern part of the Island of the Gods. The condition of the coral reefs in the Bondalem Waters area is categorized as very good, with coral reef cover percentages ranging from 65.93% to 81.33%. Besides having potential for diving tourism, Bondalem Village also boasts cultural attractions and local artistic wisdom. The purpose of this research is to identify the minatourism potential in Bondalem Village from the social aspect of the community. This research uses a descriptive quantitative method. The research process begins with the preparation of a proposal and the drafting of a questionnaire, followed by data collection, data processing, and data testing before drawing conclusions from the research activities. Based on research conducted on the potential of minatourism from the social aspect of the community in Bondalem Village, Buleleng, Bali, it is concluded that Bondalem Village in North Bali, specifically in Buleleng Regency, has minatourism potential that can be developed based on cultural, economic, and environmental assessments. The analysis of cultural, economic, and environmental aspects influencing minatourism potential, based on interviews with respondents, yielded scores of 3.253, 3.256, and 3.220, respectively, indicating that respondents support the development of minatourism potential in Bondalem Village from these aspects. This research is expected to provide useful input for various parties, especially the government, the Bondalem Village authorities, and researchers, to jointly support sustainable minatourism development.

Abstract

Healthy cookies is one of the processed pastries by utilizing the nutritional content contained in tuna fish bone by-products so that it is used as an alternative snack for people with osteoporosis. This study aims to analyze the chemical and sensory characteristics of cookies added with tuna fish bone flour. The research method used was an experimental method with two treatments, namely cookies without the addition of tuna fish bone flour and cookies with 6% tuna fish bone flour substitution which were analyzed using one-way Anova on XLStat software. The results showed that the addition of 6% tuna fish bone flour produced higher values of ash, protein and fat content, namely 3.170%, 25.878% and 43.865% while the water content and carbohydrates decreased, namely 5.488% and 21.599% The sensory results of cookies adding tuna fish bone flour received a "good" assessment of color and texture and "neutral" on aroma, taste and overall acceptability.
