the ship. Ship maneuvering, on the other hand, refers to the ability to turn and pivot while sailing. This ability is crucial for the safety of the ship, especially when operating in restricted waters or near ports. The blackout occurs as a result of generator overload or the inability of an electrical voltage and current to flow too high or too large. The load is too high because the bow thruster consumes too much electrical voltage. In fact, on KM. Dharma Kartika IX, the generator has already supplied a significant amount of electricity to various parts of the ship, including the lighting system throughout the ship, from the mast to deck 3, the cooling system, and several navigation systems. The aim of this research is to understand and explain the causes of blackouts in the electrical system of KM Dharma Kartika IX during maneuvering and to find solutions that should be implemented in case of problems with the generator unit. The method I used to gather this data is through direct observation during seagoing service on the subjects under examination.

Abstract:Islamic economics has different principles from conventional economics, including in terms of sales contracts. In Islamic economics, there are several types of sales contracts used, such as bai' al-salam (future sales) and…
nd bai’ al-salam(manufacturing sales). Trust sales contracts are also important in ensuring transparency of the price of the goods or services sold. The research method uses descriptive qualitative in describing and explaining specifically with literature studies in data collection. The purpose of this research is to find out specifically about the types and qualifications of sharia sales that do not contain gharar and usury. In Islamic economics, payments in sales contracts can be deferred or paid in installments without involving interest or riba. This allows the buyer to pay according to an agreed schedule. Sales contracts in the Islamic economy differ from interest-bearing loan contracts, where there is an exchange of goods or services at a predetermined price. Islamic banks use sales contracts as a legitimate alternative to interest-bearing loan contracts, allowing them to provide financing that is fair and compliant with sharia principles. In the Islamic economy, there are also contracts for the sale of future commodities (salam), the sale of manufacturing (istisna'), and currency exchange (sarf). Islamic banks have an important role to play in facilitating these sales contracts, as intermediaries who ensure the contracts adhere to Shariah principles and meet applicable legal requirements. With a good understanding of the different types of these sales contracts, economic actors can choose the ones that suit their needs while complying with sharia principles.

on Damer’s theory. The method used in this study is qualitative descriptive. Data has been collected in the analysis by way of presenting, describing, and interpreting data. Research results show that there are twelve data in in this study, such as structural principle (twelve data), relevance (ten data), acceptability (one Data), sufficiency (six data), and rebuttal principle (four data). The researcher found that the structural principle is most dominantly used in the argument because there is a claim from the speaker’s argument to strengthen the speaker’s statement so that it can be accepted by the audience, relevance of reasons that are directly related to the claim, acceptability of the audience's opinion regarding the speakers’ argument, sufficiency provides evidence to strengthen the argument, and rebuttal principle which is the speaker's criticism of the argument presented by the opponent. Therefore, this concluded that the most consistent during the debate was Randa saying that quotas can help gender equality while Christina said that quotas cannot work and only harm because there is no evidence that gender quotas can help equality.

ar respons siswa dapat ditelaah secara mendalam tanpa adanya perlakuan atau manipulasi terhadap variabel penelitian. Sebanyak 30 siswa kelas VIII dijadikan subjek melalui teknik purposive sampling, dan 6 di antaranya dipilih untuk sesi wawancara semi terstruktur yang mewakili tiga tingkat kemampuan akademik, yaitu tinggi, sedang, dan rendah. Pengumpulan data dilakukan melalui tes diagnostik tertulis, wawancara yang direkam, dan dokumentasi. Analisis data mengacu pada model interaktif Miles dan Huberman yang terdiri atas reduksi data, penyajian data, dan penarikan kesimpulan, dengan triangulasi metode untuk menjaga keterpercayaan temuan. Hasil penelitian menunjukkan bahwa 46,67% siswa melakukan setidaknya satu kesalahan dalam mengidentifikasi sisi kubus, 63,33% siswa melakukan kesalahan terkait rusuk, dan 36,67% siswa mengalami kesulitan dalam mengidentifikasi titik sudut secara tepat. Tiga kategori kesalahan yang dominan teridentifikasi, yaitu kesalahan konsep berupa kekeliruan mengidentifikasi unsur geometris, kesalahan visualisasi yang berkaitan dengan kesalahan membaca representasi tiga dimensi, dan kesalahan prosedural dalam menghitung komponen geometris secara sistematis. Faktor penyebab meliputi dimensi internal, terutama lemahnya pemahaman konsep dan rendahnya kemampuan penalaran spasial, serta dimensi eksternal seperti minimnya media pembelajaran dan dominasi strategi mengajar berbasis ceramah. Temuan ini menegaskan perlunya pendekatan pembelajaran geometri bangun ruang yang lebih eksploratif, konstruktivis, dan berbasis media di jenjang SMP.
This study investigates the types and underlying causes of errors made by eighth-grade junior high school students when identifying the faces, edges, and vertices of a cube. A qualitative descriptive research design was employed to examine students' responses in depth without manipulating any research variables. Thirty students from the eighth grade were selected through purposive sampling, and six of them participated in semi-structured interview sessions representing three levels of academic ability: high, moderate, and low. Data were gathered using written diagnostic tests, audio-recorded interviews, and documentation. Analysis followed the interactive model proposed by Miles and Huberman, encompassing data reduction, data display, and conclusion drawing, with methodological triangulation applied to ensure the trustworthiness of findings. Results indicated that 46.67% of students committed at least one error in identifying cube faces, 63.33% made errors related to edges, and 36.67% had difficulty identifying vertices correctly. Three dominant error categories were identified: conceptual errors, visualization errors, and procedural errors. Causal factors encompassed internal dimensions, particularly weak conceptual understanding and limited spatial reasoning ability, and external dimensions, including insufficient instructional media and lecture-based teaching strategies.
