Abstract

Dunaliella salina is a green microalgae that has the ability to produce β-carotene used in various fields, such as food supplements, natural colorant, antioxidants, anti-cancer, and anti-aging. D. salina is capable of producing large amounts of carotenoids under stressful conditions, including light and nutrient. Light is the main factor that stimulate the production of carotenoid pigments and media composition plays an important role for growth, biomass, and β-carotene production. The accumulation of β-carotene in microalgae is closely related to the type and quality of light and the composition of the culture media. This study aimed to determine the production of β-carotene in microalgae D. salina using LEDs and different culture media to select the best culture conditions for producing high value compounds. The results showed that D. salina cultured using red LED light and technical Walne media was able to produce β-carotene with the highest amount of 767,499 mg/100 g. In blue LED light and Walne Pro-analysis media, the β-carotene content was 380,522 mg/100 g, while the ZA+NPK media has the lowest value. In this study, Walne Pro-analysis media became the best culture medium for D. salina. Therefore, natural sources of β-carotene can be obtained from D. salina, so it could reduce the use of synthetic carotene in meeting global demand.

Abstract

Macroalgae or known as seaweed is one of the potential resources and is responsible for primary productivity in marine waters. Macroalgae plays an important role in marine ecosystems, provides food, oxygen, and habitat for several types of marine biota. Moreover, macroalgae have been reported as renewable resources in marine environment and widely used in various fields. The biodiversity and abundance of macroalgae are strongly influenced by aquatic environmental factors. Lemukutan Island is the largest inhabited island located in Bengkayang Regency, West Kalimantan and has the potential natural resources, including macroalgae. This Island can become a center for producing macroalgae that can be used to meet food needs both locally and domestically. The main objective of this study were to determine the community structure of macroalgae and the condition of the environmental physico-chemical parameters. The sampling locations were carried out in-situ at three stations and the determination of the sampling site was done by purposive random sampling method, by selecting an area based on the presence of macroalgae. The sampling of macroalgae was carried out using a quadratic transect with size of 10x10 m2 and the water quality parameters were measured using the AZ 8603 of WQC instrument. The study found 6 genera of macroalgae, such as Caulerpa, Halimeda, Padina, Turbinaria, Sargassum, and Gracillaria. Among the identified macroalgae, Phaeophyceae have the highest per cent contribution (50%), and Padina had the highest abundance (29.84 ind/m2). Lemukutan Island waters had a moderate level of diversity, high macroalgae uniformity, and dominance index in the low category. The aquaatic environmental factors influenced the abundance of macroalgae in Lemukutan Island waters.

Abstract

Pulau Lemukutan merupakan salah satu pulau kecil di Kecamatan Sungai Raya Kepulauan, Bengkayang, Kalimantan Barat. Keanekaragaman hayati di perairan pulau ini cukup tinggi dan melimpah, salah satunya adalah rumput laut. Rumput laut cokelat jenis Sargassum polycystum dan Padina australis paling banyak ditemukan di perairan ini dengan pemanfaatannya yang kurang optimal. Rumput laut cokelat telah banyak dilaporkan memiliki zat pengatur tumbuh (ZPT), mineral, dan senyawa bioaktif yang berpotensi sebagai biostimulan. Penelitian ini bertujuan untuk menentukan pH terbaik (asam, basa, dan netral) dalam mengekstrak kandungan nutrien dan fitohormon pada rumput laut S. polycystum dan P. australis asal perairan Pulau Lemukutan, Kabupaten Bengkayang, Kalimantan Barat. Nutrien tersebut diekstrak dari rumput laut dengan pH yang berbeda, yaitu 3, 7 dan 9. Ekstraksi dilakukan pada kondisi asam (SA dan PA), netral (SN dan PN) dan basa (SB dan PB). Kandungan nutrisi (N, P, K) dianalisis mengacu pada AOAC (Association of Official Analytical Chemist). Analisis fitohormon dilakukan dengan kromatografi cair kinerja tinggi (KCKT). Konsentrasi N, P dan K tertinggi yaitu 0,14% (SN dan PN); 0,03% (SA) dan 0,59% (SB). Hasil ini menunjukkan nutrien tertinggi terkandung pada S. polycystum dibandingkan P. australis. Fitohormon tertinggi terkandung pada S. polycystum, yaitu auksin 8,40 mg/g dan zeatin 17,99 mg/g.

Abstract

One fishery commodity that has economic value in trade both nationally and internationally is seaweed. Euchema spinosum belongs to the class of red seaweed (Rhodophyceae) which has great health benefits, because it contains high alginate, carrageenan and fiber, which are very good for digestion and are widely used in the textile, cosmetics, and other industries. E. spinosum also has several very important biological activities such as antioxidants.Lemukutan Island is a group of islands in the West Kalimantan region with the main livelihood of the population is fishing and farming. E. spinosum naturally grows a lot in the waters of Lemukutan Island. The potential for seaweed development in the area is very large, because in addition to the waters being far from urban or industrial activities so that a well-conditioned aquatic environment is very suitable as a seaweed cultivation center, this area is also shaded and protected so that it is not so affected by high waves from high seas.This activity aims to improve fishermen's skills while increasing productivity so that it can have an effect on improving the welfare of the farmers. The training was attended by 30 participants who are fish fishermen and seaweed farmers. The cultivation method applied in community service activities at this time is the floating netting method, using bamboo and a net at the bottom of the kerambah so that it protects the seaweed from predators such as fish and turtles. E. spinosum which is cultivated by the community in various ways, such as long line, off-bottom cages, is very risky to the threat of predators and being dragged by currents so that it has the potential to reduce the productivity of seaweed

Abstract

A common problem faced by coastal communities is the lack of clean water kamislot. This issue also occurs in the coastal area of Sungai Nibung Village, Teluk Pakedai District, Kubu Raya Regency. The community relies on dug well water; however, this water is yellowish, murky, and has an iron odor. This activity, in Community Service (PKM), aims to collect data on the condition of water and existing clean water fasilities and infrastructure, and offer treatment solutions that consider the current situation. The method was carried out through field surveys, raw water sampling, simple water testing (pH, salinity, and coagulation-flocculation tests), and observation of clean water supporting facilities. High levels of in the water can be reduced through coagulation-flocculation using soda ash and PAC to precipitate the iron. If the sedimentation stage is skipped, the workload of the filters in te available facilities becomes heavier. One applicable solution for the community is to add aeration and sedimentation tanks to oxidize and precipitate the iron.

Abstract

Penelitian ini bertujuan untuk menganalisis sirkulasi laut di Teluk Weda, Pulau Halmahera, dengan pendekatan spasial dan temporal. Data arus, suhu permukaan laut dan angin diambil dari produk CMEMS dan CDS untuk periode 2010–2020. Analisis dilakukan untuk mengidentifikasi pola musiman arus dan hubungan antara angin muson dan dinamika arus. Selain itu, profil vertikal arus dan distribusi arus berdasarkan transek melintang dianalisis untuk melihat pola dua lapisan (two-layer flow). Hasil menunjukkan bahwa sirkulasi arus bersifat musiman dengan arus masuk melalui Laut Maluku pada musim barat dan dari arah utara Papua pada musim timur. Komponen angin zonal dan meridional berperan besar dalam mengontrol pola sirkulasi arus. Arus permukaan lebih kuat dibandingkan arus dalam, dan pola dua lapisan tercermin dalam transek vertikal, terutama saat musim transisi. Penelitian ini menekankan pentingnya pemantauan jangka panjang terhadap dinamika arus di wilayah timur Indonesia.

Abstract

Tanah ultisol yang mendominasi wilayah Kalimantan Barat (64,83%) menghadapi kendala kesuburan utama berupa pH sangat masam dan kandungan kalium yang tersedia rendah. Penelitian ini bertujuan mengevaluasi efektivitas amelioran Turbinaria sp. segar dan fermentasi dalam meningkatkan kandungan kalium dan memperbaiki pH tanah ultisol. Rancangan Acak Lengkap diterapkan dengan tiga perlakuan: kontrol tanpa amelioran (T₀), aplikasi 100 g/kg Turbinaria sp. segar (T₁), dan aplikasi 100 mL/kg Turbinaria sp. fermentasi menggunakan EM4 selama tujuh hari (T₂), masing-masing lima ulangan. Analisis kalium menggunakan ICP-OES Agilent 5900 pada panjang gelombang 767 nm dan pH diukur dengan pH meter digital secara in situ pada hari ke-3, 7, 10, dan 14. Hasil menunjukkan perlakuan fermentasi (T₂) memberikan kandungan kalium tertinggi sebesar 0,33 cmol/kg pada hari ke-7, meningkat 65% dibandingkan kontrol (0,20 cmol/kg), sedangkan perlakuan segar (T₁) meningkat 50% (0,30 cmol/kg). pH tanah perlakuan segar mencapai nilai tertinggi 7,00 pada hari ke-10, sementara perlakuan fermentasi dan kontrol mengalami fluktuasi lebih moderat. Uji ANOVA menunjukkan pengaruh sangat nyata aplikasi amelioran terhadap kandungan kalium (F-hitung = 52,18; p < 0,001). Uji Duncan mengonfirmasi hierarki T₂ > T₁ > T₀ (p < 0,05). Turbinaria sp. fermentasi terbukti efektif sebagai amelioran organik untuk meningkatkan ketersediaan kalium pada tanah ultisol.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh aplikasi biofertilizer berbasis Padina sp. terhadap ketersediaan kalium (K) pada tanah ultisol. Tiga perlakuan digunakan, yaitu tanpa aplikasi Padina sp. (P0), Padina sp. segar (P1), dan Padina sp. fermentasi (P2), masing-masing dengan lima ulangan. Analisis kandungan K dilakukan pada hari ke-3, 7, 10, dan 14 menggunakan ICP-OES. Hasil penelitian menunjukkan bahwa perlakuan Padina sp. fermentasi memberikan peningkatan K tertinggi yaitu sebesar 0,31 cmol/kg. Proses fermentasi mempercepat dekomposisi biomassa dan pelepasan K sehingga ketersediaan unsur tersebut dalam tanah meningkat lebih cepat. Meskipun terjadi sedikit penurunan pada akhir pengamatan, nilai K pada perlakuan fermentasi tetap lebih tinggi dibandingkan perlakuan lainnya. Uji ANOVA satu arah menunjukkan pengaruh nyata (p < 0,01) pada nilai K tanah ultisol. Dengan demikian, Padina sp. fermentasi berpotensi sebagai biofertilizer alami untuk meningkatkan ketersediaan K pada tanah ultisol.

Abstract

Kuala Secapah Village serves as a prominent hub for capture fisheries along the coast of West Kalimantan. Alongside premium catches, local fishermen frequently haul trash fish (ikan rucah), that remains economically underutilized. Applying innovative and sustainable processing approaches to these marine resources can significantly generate added value for the community. This community service program aims to educate and train coastal women on upgrading these underutilized catches into competitive food products. The program was delivered in participatory workshop divided into two sessions: an instructional lecture and a hands-on culinary production practice. The intervention yielded substantial progress, with participants' technical knowledge skyrocketing from 64% to 99.6% regarding standardized and proper fish-processing techniques. Ultimately, this initiative successfully fosters local economic resilience by converting underutilized marine waste into high-value commodities.
