Land development that occurs in Pringsewu Regency is for the public interest, as a government step to more easily acquire lands which function as cultivation areas for physical development as a form of service to community needs. The limited provision of land will make it difficult for the government to develop an area as a form of land use for public purposes. This research will discuss about the analysis of land use for the public interest. There are several criteria and indicators that determine the location of land to be used for public use, consisting of land area, existing land use, spatial plan, area function, slope, land shape, soil movement, flood hazard, population density and market land prices. Based on the results of the scoring analysis of 11 indicators through the application of spatial multicriteria analysis which involves eleven criteria for determining the location as the most appropriate variable to be used as state land as a balancing material, the Pringsewu Regency government explains that zone 3 (Kecamatan Pagelaran, Pringsewu dan Ambarawa) has the most land dominance which can be prioritized first.

The green synthesis of ZnO nanoparticles was carried out using a natural capping agent, Sapindus rarak DC rinds extract at low-temperature calcination and environmentally friendly solvent. The mixture of Zn(CH3COO)2, NaOH, and rinds extract was sonicated for 4 h at room temperature. The calcination was carried out at low temperature, 95oC for 8 h, and resulted in pale brown powder. XRD and SEM were used to confirm the structure and to analyze the morphology of ZnO nanoparticles respectively. XRD pattern of ZnO nanoparticles was corresponding to JDCPS card no 36-1451 with hexagonal structure. The average crystal size of ZnO nanoparticles was calculated using the scherrer equation and the average size was about 35.8 nm. From this study, the extract of the rind of Sapindus rarak DC was found to be a natural capping agent to synthesis ZnO nanoparticles because Sapindus rarak DC contain a pythochemical compound to limit the interaction between crystal seeds.

Trend of public transport service in rural area is decreasing in terms of the number of operational route and the performance. However, there are people who cannot access private vehicles and depend on rural transport services including the elderly, people with disabilities, women, and students. The existence of this rural transportation indirectly improves the quality of life of the community by providing easier access to better economic, health and educational facilities than in the areas where they live. Responding to these conditions, the aim of this study is to analyze rural transit service needs to accommodate passengers trip. Case study of this research is rural public transport on route 061 Cilimus-Mandirancan in Kuningan Regency. This study used quantitative method with descrptive and comparative analysis. The result show that public transport needs improvement in such performance parameter like route, schedule, load factor, waiting time, baggage space, vehicle operating cost, and institutional. Improving the quality and innovation of rural public transport services can be realized if there is intervention from the government and other related parties in the management and operational costs of rural public transport vehicles.

PT PLB (pseudonym) is a company that produces household appliances and kitchen utensils. The country kettle is one type of product made by PT PLB. The productivity of the country kettle production line decreased by 56%. This was due to defective products. The largest percentage of defects in-country kettle products occurred in the spinning process of 40.18%. This study aimed to identify the causes of defects in-country kettle products and how to overcome them by designing improvement proposals. Lean manufacturing principles were used to evaluate the problems that occur. There were three types of lean manufacturing tools used in this study: Value Stream Mapping (VSM) and 5Ways. VSM was used to describe and identify value-added activities, non-value-added activities but necessary, and non-value-added activities so that the production process becomes lean. The root cause analysis was performed using the 5 Whys method. Unskilled workers and non-standard material types between suppliers are the highest contributors to defects in the spinning process. Based on this, this research was focused on improvements made in the spinning process. Proposals for improvements to the causes of the problems found are standardization of work procedures, standardization of supplier specifications, and arrangement of semi-finished goods and/or supplies. Based on the company's results, the proposed standardization of work procedures and arrangement of semi-finished goods and/or supplies may be implemented in the company. Meanwhile, the proposal for selecting suppliers is not feasible due to company limitations

Fish gelatin hydrolysate is a well- known fish by-product that is high in protein content. It is produced from by-product waste from the fish processing industry, which includes fish skin, head, and bones. Gelatin hydrolysates have recently received much attention due to its high protein content and bioactivity, which includes antioxidant, antimicrobial and antihypertensive activities. The transformation of gelatin hydrolysate into nanoparticles is believed to increase its economic value. Furthermore, reduction into nano-size increases the absorption characteristic of this material. Here, fish gelatin hydrolysate nanoparticles are prepared for the first time using desolvation method. The effects of concentration of gelatin hydrolysate, pH of solution, and acetone concentration on nanoparticle size are determined. The prepared gelatin hydrolysate nanoparticles were found to have spherical shape with sizes varying from 300-400 nm with a mean size of 408 ± 11.4 nm, zeta potential of -16.4 ± 1.2 mV and PDI 0.203 ± 0.07. This study showed that concentration of gelatin hydrolysate, pH and concentration of solvent have significant effects on nanoparticle size. The gelatin hydrolysate nanoparticles can be applied in the pharmaceutical industry for the encapsulation of drugs to facilitate delivery to target sites.
