Abstract
Shrimp paste is very much needed in NTB culinary. Several Micro small and Medium Enterprises (MSMEs) in Lombok produce shrimp paste. This study aimed to determine the chemical and physical quality of shrimp paste produced by MSMEs on the island of Lombok. The method used in this study was an experimental method with a Randomized Block Design and a single factor experiment with sampling locations, namely Shrimp paste of Putri Nyale (Jerowaru), Jero Acan (Jerowaru), TelukJor (Jerowaru), Lakara Salwa (Pringgabaya), Udang Rebon (Lembar) and SasakMaiq (BatuLayar). Each treatment was repeated three times to obtain 21 experimental units. The data were analyzed by analysis of variance at a 5% significance level using Co-Stat software. Significant different data were further tested with HSD test. The results showed that the moisture content, pH, hardness (texture) and color (Hue o) of shrimp paste from all producers were significantly different. There was a tendency that the higher the moisture content, the lower the hardness value (shrimp texture). Shrimp paste of Sasaq Maiq has the highest hardness of 39631. 98 kg/cm2 with the lowest moisture content of 23.21 %. Shrimp paste of Putri Nyale has the lowest hardness with the highest moisture content of 37. 55 %. Moisture content of Lakara Salwa shrimp paste and SasakMaiq does not meet the quality standards of shrimp paste (SNI 01-2716.1-2009). The acidity level of shrimp paste produced by MSMEs in Lombok is significantly different with a range of 6.4 to 7.57 which is influenced by the length of fermentation applied. Based on Hue°, the Lakara Salwa shrimp paste produces a red color range due to the use of dyes and other shrimp paste has a yellow red color with the use of natural raw materials.

Abstract
Preparation process for meniran (Phillantus urinaria) functional drink (MFD) influences its antioxidant activity. This research aims to understand the phenolic content, DPPH Radical Scavenging Activity (RSA), and LDL oxidation of MFD through various preparation processes. Those preparation processes included soaking fresh meniran (SFM), boiling fresh meniran for 5 minutes (BFM5’), boiling fresh meniran for 10 minutes (BFM10’), and soaking dried meniran (DM). The phenolic content was determined with Folin–Ciocalteu, antioxidant activity was assessed using DPPH and TBARS assay with LDL as the oxidation substrate. An antioxidant references in this research used ascorbic acid. The phenolic content in methods of SFM, BFM5’, BFM10’ and DM were 122±0.022, 182±0.043, 192 ±0.03, and 117 ±0.019 mg GAE/g of meniran respectively. Meanwhile, the DPPH RSA of SFM, BFM5’, BFM10’ and DM accounted for 82.18±0.35, 86.19±0.53, 86.75±0.64 and 69.96% respectively. As comparison, the DPPH RSA of ascorbic acid 50 ppm is 75.65±0.82%. At the same time the optimum inhibition of TBARS formation from BFM5’ and BFM10’ methods were 45.83 % and 48.66%, with MDA concentration in human LDL accounted for 38.30±2.39 and 36.30±1.82 nmol MDA/mg protein, respectively. As comparison, MDA concentration in human LDL added with ascorbic acid 25 ppm accounted for 41.35±2.41 nmol MDA/mg protein. In contrast, the control human LDL was 70.70±2.35 nmol MDA/mg protein. This study concludes that the BFM5’ and BFM10’ methods showed the highest antioxidant properties compared to other methods. All methods showed that MFD extract in concentration more than 25 ppm increased the concentration of MDA in human LDL. Therefore, to produce meniran functional drink in optimum antioxidant properties is best by using BFM5’ and BFM10’ preparation methods in meniran concentration of not more than 25 ppm.

Published: December 2021

AbstractThe Kebon Kongok Regional Landfill (TPA) is one of the final processing sites serving West Lombok Regency and Mataram City. The Landfill is managed by the Regional Technical Implementing Unit (UPTD) of the Regional Waste Landfill of NTB Province under the Department of Environment and Forestry of NTB Province. Currently, waste services in Mataram City and West Lombok Regency have not met the sanitation target. One of the factors that affects it is the financial problem where there is no budget flexibility which often causes difficulties in handling operations, especially at the beginning and end of the year. Therefore, the purpose of this study is to determine the institutional development strategy as an effort to increase the role of UPTD in solid waste services. The analytical method used is Force Field Analysis (FFA). Based on the FFA, it is found that the Total Weight Value (TNB) driving forces are more significant than the restraining forces; this means that UPTD of Regional Waste Landfill of NTB Province is encouraged to carry out institutional development. Therefore, the institutional development strategy is that UPTD applies for the Financial Management Pattern of Public Service Agencies (PPK-BLUD).

Published: December 2021

Abstract
Despite the fact that North Jakarta has been prompted as the new frontier of development with megaprojects, artificial islands, and large-scale infrastructures, little attention is paid to the development of small islands in Kepulauan Seribu, north of Jakarta, focused on Panggang island, one of the inhabited islands in Kepulauan Seribu, among Indonesia’s densest islands. There were the three challenges to the urbanization of small islands in the Jakarta megaregion, including: population growth, land availability and reclamation, and essential infrastructure provision. Through a participatory workshop with local authorities and communities, this paper proposed a model of sustainable settlement planning in Panggang Island, based on housing need assessment and spatial structure improvement to ensure the future settlement sustainability in Panggang island. To conclude, this paper critically reflects on the engagement process with local communities and the challenges in actualizing the settlement planning proposal in Pulau Pangang.

Abstract
The influence of incentives on landowner’s decision-making regarding land-use change is an intriguing consideration when developing sustainable agricultural land policies. Owners of agricultural land in rural areas with varying characteristics and varying agricultural yields each year have varying views on changing or maintaining their land. The purpose of this study was to determine the effect of incentives on people’s attitudes toward maintaining or selling land (land-use change from agricultural land to non-agricultural land). This study employed a descriptive analysis to calculate the impact of incentives from the government on the decision to change or keep the land. The responses of 500 respondents were categorized as follows: 20-46.67 in favor of land change, 46.67-73.33 neutral, and 73.4-100 in favor of maintaining land. The analysis revealed that additional factors influence the decision to sell or maintain the land. However, some villages seek to preserve land through government incentives.

Published: December 2021

AbstractThe present work deals with the recently confirmed widening of the weld pool interface, known as a bulging effect, and its relevance in high power laser beam welding. A combined experimental and numerical approach is utilized to study the influence of the bulge on the hot cracking formation and the transport of alloying elements in the molten pool. A technique using a quartz glass, a direct-diode laser illumination, a high-speed camera, and an infrared camera is applied to visualize the weld pool geometry in the longitudinal section. The study examines the relevance of the bulging effect on both, partial and complete penetration, as well as for different sheet thicknesses ranging from 8 mm to 25 mm. The numerical analysis shows that the formation of a bulge region is highly dependent on the penetration depth and occurs more frequently during partial penetration above 6 mm and complete penetration above 8 mm penetration depth, respectively. The location of the bulge correlates strongly with the cracking location. The obtained experimental and numerical results reveal that the bulging effect increases the hot cracking susceptibility and limits the transfer of alloying elements from the top of the weld pool to the weld root.

Published: December 2021

Abstract
Hybrid additive manufacturing (HAM) describes the combination of additively built structures onto a conventionally manufactured base body. The advantages of both manufacturing processes are combined in one process chain. As a result, new applications can be achieved with higher cost-effectiveness. With the Additive Manufacturing (AM) process a bonding zone is created that is comparable to a welded joint. In order to evaluate the quality and mechanical properties of the bonding zone, two steels (42CrMo4 and 25CrMo4) are investigated as base body materials with the hot working tool steel X40CrMoV5-1 (AISI H13) for the AM structure. Process parameters for Laser-based Powder Bed Fusion of X40CrMo4V5-1 are developed to achieve a crack and defect free structure as well as an optimized bonding zone in dependency of the base body material. Furthermore, the chemical and mechanical properties are examined in the as-built and heat-treated state. It is observed that a crack-free material bonding is possible and samples with relative densities above 99.5% are obtained. The size of the bonding zone depends on the material of the base body as well as post-process heat treatment. An average hardness of 600 HV1 can be achieved in the “as-built” state.
