Proposed Improvement of Trans Semanggi Suroboyo Services Using IPA and QFD Methods
Full text linkThe high intensity of private vehicle usage has led to uncontrolled road congestion. To encourage residents to switch to public transportation, the Surabaya City Government introduced Trans Semanggi Suroboyo. Trans Semanggi Suroboyo experienced a decrease in passengers in 2023, with a decline of 324,711 passengers. Based on a preliminary survey with direct interviews conducted with 35 Trans Semanggi Suroboyo passengers, frequent complaints were related to service and facilities. Therefore, it is important to analyze and propose improvements to the services of Trans Semanggi Suroboyo as public transportation in Surabaya. To enhance the quality of services and facilities, it is essential to identify and evaluate passenger perceptions using service quality dimensions based on the Decree of the Director General of Land Transportation Number SK.5923/AJ.005/DRJD/2016. The most important service quality priorities for passengers are measured using the Importance Performance Analysis (IPA) method. This research identified 9 critical attributes that require improvement. Subsequently, a service quality improvement design was developed using the Quality Function Deployment (QFD) approach through the House of Quality (HoQ) matrix, resulting in 5 priority technical responses. Based on these findings, a plan for improving the service and facilities of the Trans Semanggi Suroboyo bus was proposed to maintain the quality of public transportation services
Production of Biomass and Bioactive Compound as a-Glucosidase Inhibitor Activities Simplisia Cat Whiskers (Orthosiphon aristatus) at Fertilization and Differences Harvest Rotation Time
Full text linkCat whiskers are traditional medicinal plants with bioactive compounds like flavonoids like sinensetin. The development of cat whiskers as a medicinal plant is still constrained by the quality of the simplisia. Fertilization and harvesting are essential aspects of the cultivation of medicinal plants. The research aims to determine the proper fertilization and harvest rotation time differences to produce biomass production and bioactive compound simplisia in cat whisker leaves. The method used was a Randomized Complete Block Design composed of two factors. The first factor was harvest rotation, consisting of four and six levels. The second factor was fertilization, composed of three levels, namely 100 g Indigenous Arbuscular Mycorrhizal Fungi (AMF) inoculum, 2.1 g Urea (N fertilizer) & 2.7 g SP-36 (P fertilizer), and a combination of 100 g Indigenous AMF inoculum + 2.1 g Urea (N fertilizer) & 2.7 g SP-36 (P fertilizer). The results showed that the highest simplisia biomass production was obtained by giving a combination fertilizer (Indigenous AMF, N & P). In contrast, the highest simplisia bioactive compound production was obtained with indigenous Arbuscular Mycorrhizal Fungi (AMF) fertilizer or a combination fertilizer (Indigenous FMA, N & P). Production of biomass and bioactive compounds of cat whisker plants simplisia can be done by harvesting earlier every four weeks or extending the harvesting time to every six weeks
The Graded Concentration of Bleach Solution and Material Size Plays an Important Role in the In Vitro Sterilization of Thyphonium flagelliforme Plants
Full text linkThe sterilization is a primary step in in-vitro culture. plant breeding through in-vitro culture hinges on the successful effectiveness of the sterilization method in producing sterile plants.

The study revealed that Material sizes do not have a significant effect on contamination level, all the same, large size materials increase the survival rate of sterilized rodent tuber plants. The application of graded bleach solution concentrations at 25%, 20%, and 15% is able to reduce contamination to 0% on small size materials and 5 % on large size materials. Material sizes do not have a significant effect on contamination level, all the same, large size materials increase the survival rate of sterilized rodent tuber plants
Notarial Challenges for Aircraft Deeds: Unlocking the Potential of Aircraft as Collateral
Full text linkA notary is a public official entrusted with the authority to draft legal deeds pertaining to agreements within the scope of private law. However, their ability to fulfill this role is limited when they are unable to draft aircraft mortgage deeds. This study aims to critically evaluate the scope of a notary's authority in preparing aircraft-related deeds and to examine the various forms of legal deeds that have emerged in practice when aircraft are used as collateral in credit agreements. Using a normative legal approach, the research employs statutory analysis, conceptual exploration, and interpretative methods to assess legal materials. The findings reveal that notaries face considerable obstacles in exercising their authority due to the lack of specific regulations on aircraft mortgages, even as the aviation industry continues to grow rapidly. This regulatory void has resulted in the emergence of diverse deed types, such as Deeds of Agreement for the Transfer of Guarantee and Grant of Power of Attorney, Fiduciary Deeds, and Deeds for the Transfer and Guarantee of Power of Attorney. Furthermore, as aircraft, categorized as registered objects, can be classified as immovable property and potentially treated as mortgageable collateral, the establishment of specific regulations governing aircraft mortgages is essential to avoid legal uncertainty and ensure clear regulatory guidance

Indonesia Passenger’s Right Compensation for Transport Accidents: Is It Fulfilling a Sense of Justice?
Full text linkThe mode of transportation—whether on land, at sea, or in the air—plays a crucial role in passenger mobility across various countries. Between passengers and carriers, binding contracts establish their legal relationship. However, a persistent issue remains: to what extent should carriers be held liable in cases of loss, injury, or death of passengers, and what are their obligations regarding compensation? The key question revolves around the scope of the carrier's responsibility to compensate passengers. As such, regulations governing carrier liability and compensation have become a critical focus in international legal studies, including in Indonesia, with comparisons drawn to several Southeast Asian countries. This research employs normative legal methodology with a conceptual framework. It is analyzed descriptively using a qualitative approach and concludes through deductive reasoning. The findings suggest that passenger compensation in several Southeast Asian countries does not fully satisfy the sense of justice. While there are regulations addressing compensation, they are often insufficiently stringent. In cases where accidents lead to legal action, the compensation amount is typically determined by the presiding judges on a case-by-case basis.
Experimental Study of HRS-WC Asphalt Mixture Using Limestone as Aggregate Substitute in Cantabro Test
Full text linkThe commonly used materials in asphalt mixtures are coarse aggregates, fine aggregates, and filler. In flexible pavement mixtures, river stones serve as coarse aggregates, sand as fine aggregates, and cement as filler. However, their availability is limited and their prices are relatively high. This study aims to analyze the wear of HRS-WC mixture using limestone material as an aggregate substitute. The mixture consists of 16% crushed stone aggregate 1-2, 30% crushed stone aggregate 0.5-1, 52% fine aggregate, and 2% filler, based on the 2018 Bina Marga specifications in the laboratory. The optimum asphalt content for the mixture obtained from the Pb calculation is 5.8%, 6.3%, 6.8%, 7.3%, and 7.8%. Wear resistance of the specimens is planned to be tested using Cantabro testing method. The Cantabro test results show that the wear rate at an asphalt content of 6.8% is 3.72%, meeting the Bina Marga specification with a wear value ≤ 20%. Thus, the use of limestone can fulfill the requirements as an aggregate substitut
