STRATEGI PENINGKATAN FASILITAS DI PELABUHAN PERIKANAN LAMBADA LHOK, ACEH BESAR
Get PDFThe Lambada Lhok Fish Landing Base (PPI Lambada Lhok), strategically located in Aceh Besar District, serves as an important fisheries port. However, its current infrastructure remains insufficient to support optimal fishing activities. This study aimed to develop strategic recommendations for improving the facilities and operational performance of PPI Lambada Lhok. Primary data were collected through direct observation, questionnaires, and semi-structured interviews with purposively selected stakeholders. Secondary data, encompassing fishing gear inventories, landing volumes, fleet composition, and existing infrastructure, were obtained from the port management authority. Data were analysed using SWOT analysis, followed by prioritization of strategic alternatives through the Quantitative Strategic Planning Matrix (QSPM). The QSPM results identified three priority strategies: (1) dredging the port basin to maintain adequate navigational depth and ensure smooth vessel operations (TAS = 5.969); (2) increasing the number of fishing vessels above 5 gross tonnes (GT) to enhance fleet capacity (TAS = 5.598); and (3) upgrading port facilities to support increased production of key fishery commodities, leveraging the resource potential of Fisheries Management Areas (WPP-NRI) 571 and 572 (TAS = 5.562). Implementation of these prioritized strategies is strongly recommended to port authorities and relevant stakeholders to accelerate the development and operational efficiency of PPI Lambada Lho
THE INFLUENCE OF LENGTH OF SOAMING POWDER FISHING TOOLS ON FRESHWATER LOBSTER CATCH RESULTS(Cherax quadricarinatus) IN TELAGO VILLAGE KERINCI LAKE
No full textKerinci Lake is a type of tectonic lake located in the Kerinci Regency, Jambi Province. The fishing gear such as tangkul/ pesap, nets (trawls), and traps (lukah) are commonly used in Telago Village. This research aims to investigate the effect of soaking duration of trap fishing gear on the catch of freshwater lobster. This research was conducted from February 27 to March 18, 2024. An experimental fishing method was employed, comparing soaking durations of 24 hours and 12 hours. Quantitative data were analyzed using frequency of occurrence, followed by T-test analysis. The results showed that a 24-hour soaking period yielded 237 lobsters with an average weight of 34.75 grams, with the highest frequency of occurrence at 44% and the lowest at 24%, averaging 33.20%. In contrast, a 12-hour soaking period resulted in 119 lobsters with an average weight of 33.88 grams, with the highest frequency of occurrence at 32% and the lowest at 8%, averaging 17.60%. T-test analysis indicated no significant effect of soaking duration on the number of lobsters caught, average weight, or depth-related environmental parameters. However, significant effects were observed for environmental parameters such as temperature and pH. In conclusion, while soaking duration does not significantly affect the catch of freshwater lobster (Cherax quadricarinatus), the 24-hour soaking period resulted in a higher yield
Apakah CG Disclosure dan ROE Mempengaruhi Financial Distress?
Get PDFFinancial Distress (FD) is a critical stage requiring an accurate early warning system. Previous studies identify profitability (Return on Equity - ROE) and Corporate Governance (CG) as key determinants. However, gaps exist regarding CG's weakening effectiveness under pressure and the challenging interpretation of high profitability in the Indonesian context. This study aims to examine the effect of the Corporate Governance Disclosure Index (CGDI) and ROE on FD probability. The methodology employs Logistic Regression on 256 companies from the Cyclical Industry (2023–2024). Variables and measures utilized include: FD as the binary dependent variable (Springate S-Score), CGDI and ROE as an independent. The model was found to be simultaneously significant in predicting FD, yet the Hosmer and Lemeshow Test indicated the model is not fully fitted. Individually, CGDI has no significant effect on FD. This finding supports the view that formal CG mechanisms lose monitoring effectiveness under financial pressure (distress), often acting as mere formal legitimacy (Legitimacy Theory). Conversely, ROE has a significant and positive effect on FD probability. This counter-intuitive finding is interpreted as illusory profitability or earnings management due to strong managerial incentives (Agency Theory). High ROE becomes a misleading signal, reinforcing that profitability interpretation is a major issue within the Indonesian distress context. Consequently, the findings highlight the imperative for market participants to shift analytical focus toward underlying cash flow and liquidity indicators, while demonstrating the need for internal CG mechanisms beyond mere disclosure to effectively mitigate financial distress risk in the Indonesian market environment
Implementasi Sanksi Adat bagi Calon Mempelai dalam Pemutusan Hubungan Pertunangan (Studi Penelitian di Desa Meurandeh, Kecamatan Lembah Sabil, Kabupaten Aceh Barat Daya)
Get PDFEngagement as a stage before marriage is expected to proceed as it should. However, along the way, various problems arise that lead to the dissolution of the engagement. If it is broken, sanctions will certainly be imposed. The purpose of this paper is to examine the implementation of customary sanctions for prospective brides and grooms in the termination of engagement in Meurandeh Village, Lembah Sabil District, Southwest Aceh Regency. The research method used is the empirical juridical method. The results of the study indicate that the implementation of sanctions is carried out according to the form of the sign given during the engagement. If the sign given in the engagement is gold, then the gold is returned to the groom (if the guilty party is a woman). However, if the guilty party is the man, then the gold is forfeited (remains the property of the woman), the man no longer has any rights to the gold. If the sign given in the engagement is a sum of money, and the guilty party is a woman, then the money given must be returned to the groom twice as much. However, if the guilty party is the man, then the money that has been given is forfeited and becomes the property of the woman. It is recommended that village customary officials strengthen the delivery of information regarding sanctions during engagements, so that prospective brides and grooms are committed to carrying out the engagement until the marriage contract and marriage.
COMBINATION OF VCO (Virgin Coconut Oil) AND FISH OIL IN COMMERCIAL FEED ON THE GROWTH AND SURVIVAL OF FRESHWATER POMFRET FISH (Colossoma macropomum)
Get PDFPomfret (Colossoma macropomum) is a freshwater fish that is one of the leading commodities in Indonesia, and has good prospects for development because it has a delicious and savory taste. The obstacle that is often faced today in pomfret cultivation is the high Feeding Rate value in pomfret fish is not comparable to the growth produced by efforts made to increase growth and survival in pomfret fish, namely by adding VCO and fish oil to commercial feed. The research design used in this study was an experimental method using a Completely Randomized Design (CRD) with 4 treatments and 3 replications where P1: 7% Fish oil / kg feed, P2: 5% Fish oil + 2% VCO / kg feed, P3: 3% Fish Oil + 4% VCO / kg feed, and P4: 7% VCO / kg feed. The results obtained on absolute weight growth showed the best treatment, namely in P3, which was 10.46 g, while the best survival rate was in P1, which was 96.67%. In P1, where fish oil is 7% with a survival value of 96.67%, this is because fish oil contains omega-3 fatty acids such as DHA and EPA which are important for increasing the immunity and physiological function of pomfret fish

Pengaruh Penambahan Tembaga (Cu) terhadap Kekerasan Aluminium Berbasis Daur Ulang Limbah Otomotif
Get PDFPerkembangan industri otomotif berbanding lurus dengan peningkatan komponen kendaraan, khususnya alumunium. Alumunium memiliki sifat kemampuan daur ulang yang baik sehingga dapat dilakukan penambahan tembaga (Cu) untuk meningkatkan sifat mekanis. Limbah alumunium diperoleh dari limbah tromol sepeda motor dan kabel yang berisi tembaga sebagai bahan tambah dilebur menggunakan krusibel garfit pada temperatur 680º C - 723º C diaduk selama 15 menit menggunakan sistem stirrer casting. Penambahan tembaga (Cu) sebanyak 10 dan 20% berat total. Hasil uji, menunjukan penambahan tembaga (Cu) pada aluminium daur ulang berpengaruh terhadap kekerasan dan kekuatan tarik paduan Al-Cu. Kekerasan mikro Vickers meningkat dengan penambahan Cu hingga 10%, mencapai nilai tertinggi rata-rata 132Hv, namun menurun pada penambahan 20% Cu menjadi 130Hv. Kekuatan tarik juga mengalami peningkatan hingga penambahan 10% Cu (6.1 kg/mm2), diikuti penurunan pada penambahan 20% Cu (4.6 kg/mm2). Struktur mikro menunjukkan bahwa peningkatan kandungan Cu meningkatkan jumlah fasa θ (CuAl2) yang dapat berpengaruh sifat mekanik Al-Cu. Penelitian ini dapat berkontribusi penting dalam pengolahan limbah aluminium otomotif dengan menunjukkan potensi penambahan tembaga untuk meningkatkan kekerasan dan kekuatan tarik paduan Al-Cu hasil daur ulang, meskipun perlu diperhatikan penambahan Cu yang optimal agar tidak menurunkan sifat mekanik
