Abstract

Indonesia has marine biological natural resources consisting of fish, seaweed, crabs and shrimp which are very potential. The purpose of this study was to determine the composition of pigments in Ulva sp (Chlorophyta), Padina australis (Paeophyta) and Hypnea sp (Rhodophyta) obtained from Tablolong waters. The method used in this research is descriptive qualitative and quantitative. Proof of pigment in samples using thin layer chromatography (TLC). The results of pigment analysis of Ulva sp obtained twelve color spots with identified pigment types consisting of chlorophyll a, chlorophyll b, xanthophyll, b-carotene and feofitin. The pigment content identified in Padina australis samples are chlorophyll b, feoforbid, xanthophyll, chlorophyll a, carotene and feofitin a. The types of pigments identified in Ulva sp include pigment chlorophyll a, chlorophyll b, carotene and feofitin from the total color spots formed. Based on the results of this study concluded that non-cultivated seaweed obtained from Tablolong waters contains carotenoid and chlorophyll pigments. Suggestions from this study are expected to do an analysis of pigment content analysis in the dry season time period and continued with antioxidant testing.  Indonesia memiliki Sumber Daya Alam hayati laut yang terdiri dari ikan, rumput laut, kepiting dan udang yang sangat potensial.

Abstract

Macroalgae live on the bottom of the waters where sunlight can still penetrate like land plants. Like macro algae in general, green algae have chlorophyll or other accessory pigments that are used for photosynthesis. This color composition is used to classify the types of macroalgae. The purpose of this study was to determine the composition of the types of pigments contained in green algae. This research was conducted in September - November 2021 in Bolok Marine Waters, Kupang Regency. The identification process of algae species and pigment extraction was carried out at the Biology Laboratory of Artha Wacana Christian University Kupang, Thin Layer Chromatography (TLC) and Spectrophotometric Methods were used to identify pigment types. The results of the collection found three species of green algae: Ulva lactuca, Ulva reticulata, and Halimeda opuntia, these three types of algae were found in the intertidal zone which is still influenced by tides. Thin Layer Chromatography results for these three green algae obtained 4 - 5 fractions with a range of Retention Factor (Rf) value 0.2 – 1.0. The Rf value of 1 in the first fraction was identified as b-carotene pigment, the Rf value of 0.6 and 0.5 in fractions 2 and 3 was an indicator of chlorophyll pigment, the gray Rf value of 0.4 is a type of pheophytin pigment, while the Rf value of 0 The yellow ,3 and 0.2 are indicators of the type of lutein pigment (xanthophyll).

Abstract

Seaweed cultivation in the marine waters of Banli, OP Village, Nunkolo District, South Central Timor Regency, has never been carried out by residents of the area. This cultivation activity is to provide new jobs for the Banli Jaya fishing group in particular and it is hoped that later this group will share with other residents. This activity is also a solution for residents whose livelihoods only choose beach pebbles to sell, which in the long term will damage coastal construction which can later lead to coastal degradation and erosion.This activity is intended to train the community so that they know how to cultivate seaweed. This will be a new source of livelihood for the Banli Jaya group in particular and the population in general.Although Banli Waters is located in the South Coast region which is known for strong currents, the timing of cultivation is an important point that must be considered. The timing of June to December is the right time because in this season the southern waters are relatively calm. The Community Service Activities (PKM) for Red Algae Cultivation Kappaphycus alvarezii were carried out well, where the red algae cultivated grew well.

Abstract

Tempat Pendaratan Ikan (TPI) Oeba merupakan salah satu fasilitas atau tempat terjadinya transaksi penjualan hasil tangkapan ikan di Kota Kupang. Hasil tangkapan nelayan didaratkan di TPI Oeba beraneka ragam jenis terdiri dari ikan pelagis kecil dan besar, ikan demersal serta hasil laut lainnya. Ikan selar kuning (Selaroides keptolepis Cuvier, 1833) merupakan salah satu jenis ikan pelagis kecil hasil tangkapan nelayan yang didaratkan di TPI Oeba Kota Kupang. Jenis ikan ini termasuk ikan ekonomis penting yang sangat diminati oleh masyarakat di Kota Kupang. Penangkapan ikan selar kuning (Selaroides keptolepis Cuvier, 1833) terjadi selama musim tangkap di sekitar pesisir pantai. Adanya penangkapan secara terus menerus kemungkinan akan berpengaruh terhadap beberapa aspek biologi reproduksi seperti ukuran dan sebaran panjang, tingkat kematangan gonad, indeks kematangan gonad dan faktor kondisi. Tujuan penelitian ini adalah mendeskripsikan aspek biologi reproduksi ikan selar kuning (Selaroides keptolepis Cuvier, 1833) yang didaratkan di TPI Oeba Kota Kupang. Metode penelitian yang digunakan adalah survei pasar, dengan teknik pengambilan data dilakukan secara random sampling. Waktu penelitian dilakukan selama bulan Oktober-November. Berdasarkan analisis hubungan panjang berat, maka pola pertumbuhan ikan selar kuning (Selaroides keptolepis Cuvier, 1833) yang didaratkan di TPI Oeba bersifat allometric negatif dengan nilai b < 3. Sebaran ukuran panjang ikan selar kuning antara bulan Oktober dan November berbeda. Hasil pengamatan visual terhadap tingkat kematangan gonad terdiri dari TKG I, II dan III. Indeks kematangan gonad tertinggi pada TKG III yaitu 0,967 (ikan jantan) dan 1,012 (ikan betina). Nilai faktor kondisi ikan selar bulan Oktober-November sebesar 1. Oeba Fish Landing Site (TPI) is one of the facilities or places where fish catch sales transactions occur in Kupang City. Fishermen's catches are landed at TPI Oeba in various types consisting of small and large pelagic fish, demersal fish and other marine products. Yellowstip shad (Selaroides leptolepis Cuvier, 1833) is one of the small pelagic fish caught by fishermen landed at Oeba TPI in Kupang City. This fish species is an economically important fish that is highly demanded by the people in Kupang City. Catching yellowstrip shad (Selaroides leptolepis Cuvier, 1833) occurs during the fishing season around the coast. The existence of continuous fishing is likely to affect several aspects of reproductive biology such as size and length distribution, gonad maturity level, gonad maturity index and condition factors. The purpose of this study is to describe the reproductive biology aspects of yellowstrip shad (Selaroides leptolepis Cuvier, 1833) landed at TPI Oeba, Kupang City. The research method used was a market survey, with data collection techniques carried out by random sampling. The research time was conducted during October-November. Based on length-weight relationship analysis, the growth pattern of yellowstrip shad (Selaroides keptolepis Cuvier, 1833) landed at Oeba TPI is negative allometric with the value of b < 3. Length distribution of yellwstrip shad between October and November is different. Visual observation of gonad maturity level consisted of TKG I, II and III. The highest gonad maturity index in TKG III is 0.967 (male) and 1.012 (female). The value of the condition factor of yellowstrip shad in October-November was 1.

Abstract

The rapid expansion of digital payment technologies has transformed financial transaction behavior, particularly in emerging urban environments. However, adoption decisions are influenced not only by technological functionality but also by psychological factors. This study examines the effect of perceived ease of use on digital payment usage decisions, with trust positioned as a mediating variable. A quantitative approach was employed using survey data collected from 96 digital payment users in Kupang City, Indonesia. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results indicate that perceived ease of use has a significant positive effect on trust (β = 0.870, p < 0.001) and usage decision (β = 0.612, p < 0.001). Trust also significantly influences usage decision (β = 0.295, p = 0.020) and partially mediates the relationship between perceived ease of use and usage decision. The model demonstrates substantial explanatory power, with R² values of 0.757 for trust and 0.776 for usage decision, and a good model fit (SRMR = 0.042). These findings extend the Technology Acceptance Model by demonstrating that usability influences digital payment adoption through both direct functional pathways and indirect trust-building mechanisms. The study highlights the strategic importance of integrating usability and trust to promote digital payment adoption in emerging urban contexts.

Abstract

This study examines the development of a value chain based strategic management accounting model in private higher education institutions. The issue has become increasingly important in a competitive higher education environment, where institutions are required to manage academic and managerial activities more strategically to create value and sustain competitiveness. Using a qualitative case study approach, the study was conducted across three private higher education institutions. Data were collected through in depth interviews, observations, and document analysis, and were examined using open coding, axial coding, and selective coding procedures. The analysis focused on identifying the interdependencies among primary and support activities within the institutional value chain and assessing their contributions to value creation. The findings show that value creation is achieved through the integration of academic functions and support systems, while strategic management accounting plays an important role in generating relevant cost and performance information for managerial decision making. This integration contributes to stronger institutional reputation, improved accreditation outcomes, and greater financial sustainability. The study concludes that the proposed model can support competitive advantage by aligning value chain activities with strategic information needs, thereby strengthening managerial responsiveness and long term institutional performance.
