Abstract

The Bureau of Human Resources, Organization, and Administration (SDMOT) of the Cabinet Secretariat experienced a performance decline in 2018, with personnel services decreasing by 6.98%, training utilization decreasing by 7.77%, and satisfaction with personnel service output decreasing by 7.71%. This decline is suspected to be due to a lack of group cohesiveness and work motivation among SDMOT employees. The purpose of this research is to determine the impact of group cohesiveness and work motivation on the performance of the SDMOT Bureau. This study uses a quantitative approach. Validity testing was conducted using expert judgment, discrimination power using the item-total correlation analysis technique, and reliability using Cronbach's alpha variance analysis, while data analysis used multiple regression techniques. The results show a very strong relationship between group cohesiveness and performance. The adjusted R2 value of group cohesiveness on performance is 0.644, which means that group cohesiveness contributes 64.4% to performance. Work motivation has a significantly positive effect on performance. The adjusted R2 value is 0.678, indicating that work motivation contributes 67.8% to performance. Together, group cohesiveness and work motivation on performance are seen from the correlation coefficient (R) of 0.861, which shows a very strong relationship between the independent variables of group cohesiveness and work motivation with the dependent variable performance. The combined contribution of group cohesiveness and work motivation to performance is 72.7%, while 27.3% is influenced by other variables outside the study.

Abstract

This research aims to determine the role of public relations communication in educational institutions. This research uses various research methods, one of which is library research. Research carried out in libraries using books, journals, previous research and other sources is called library research. The steps for setting goals and the stages of knowing the direction of the target components must be understood by humans before choosing strategies to be used in the classroom. In reality, there are many obstacles that must be overcome in creating public relations communications. Higher education institutions serve as valuable tools for human development and the creation of a better future. Each member of the institution will experience development and change according to the color and pattern of the organization. Public relations can be used to carry out an organization's strategic communications initiatives, but management must fully support public relations. The purpose of this article is to discuss the role of public relations in educational organizations globally. The practice of public relations or public relations has developed and continues to develop, whether consciously or not, as a result of increasingly fierce competition to win public attention. There are many ways used by institutions or companies to explain their programs or policies, even their advantages, but the main goal is to convey them to the public by empowering public relations or public relations, who in this case are tasked with conveying information to the public.

Abstract

Talang Gulo Final Disposal Site (FDS) has a Leachate Treatment Plant (LTP) equipped with denitrification and nitrification facilities which function to reduce the concentration of ammonia (NH3) in leachate according to predetermined environmental quality standards. Research samples were taken in the form of leachate using the grab sampling method in accordance with SNI 6989.59:2008. The results of the research showed that the aeration time for the ammonia stripper of 3 hours, 6 hours and 12 hours both gave the highest value for the ammonia stripper efficiency percentage variable. The highest ammonia removal efficiency is aeration time of 12 hours. However, if we look at the operating efficiency of the ammonia stripper, the removal of ammonia by using an aeration time of 12 hours does not provide a significant improvement when compared to a treatment with an aeration time of 6 hours. This means that the operating time is 6 hours faster, the 6 hour variation can provide an ammonia removal efficiency of more than 90%

Abstract

A submersion tank bunker is a storage place for fuel oil tanks at public fueling stations (gas stations). Its function is to localize oil splatters so as not to pollute the soil below if there is a leak in the oil tank. The construction of the submersion tank bunker at the Kelapa Gading gas station in North Jakarta, the basic soil condition is muddy due to low groundwater. This condition is improved by applying a covering layer of bamboo mattress. Bamboo mats are made from wormwood bamboo (Gigantochloa Apus) which is split 5 cm wide each sheet, and then woven to form a woven grid. The presence of groundwater at the bottom of the excavation, drained by pumping out (dewatering). After laying sand, the next step can be casting the bunker concrete floor slab. It is proven that woven bamboo in the form of bamboo mattresses is an alternative to basic soil improvement that can increase the carrying capacity of basic soil effectively.

Abstract

Indonesia is the country with the fourth largest population in the world. In 2022, waste in Indonesia reached 36.00 million tons/year. DKI Jakarta Province has a vast waste generation rate of 3.10 million tons/year potentially ending in a waste processing site called TPST Bantargebang. The DKI Jakarta Province recorded as much as 7,000 to 8,000 tons/day of waste entering the TPST Bantargebang, with a regional waste reduction target of 27.00%. TPST Bantargebang has reduced waste by processing waste into fuel and electricity. Another reduction factor that has yet to receive attention is the role of waste pickers. In 2022, the number of waste pickers at TPTS Bantagebang is 6,413 people. This research examines the potential role of waste pickers in reducing waste at the TPST Bantargebang. This research is an observational study conducted by sampling and interviewing the waste pickers. The sample in this research was 98 waste pickers who collected waste samples for eight consecutive days. The results show that waste pickers at TPST Bantargebang potentially reduced 144.08 kg of waste/person/day, with the most prominent composition being plastic waste at 49.88%. Based on these results, it can be concluded that scavengers at TPST Bantargebang can reduce waste by up to 12.55%. The value of potential waste reduction by waste pickers can be used for waste reduction calculations at TPST Bantargebang.

Abstract

Sewage sludge is a major by-product of the wastewater biological treatment process. Wastewater Treatment Plants at Palm Oil Mills (PKS) produce a lot of sewage sludge and until now it has not been optimally utilized. This study aims to examine the potential of PKS sewage sludge as an adsorbent for the removal of kromium (Cr) by the fixed bed column method. The study will also analyze the effect of recirculation on the reduction of kromium levels. The sludge was carbonized in a furnace at 300°C for 2 hours. Synthetic kromium wastewater was made at three concentrations of 2000 ppm, 3000 ppm, and 4000 ppm. The sludge adsorbent used was 100 grams which was filled into the fix bed column. Recirculation of kromium wastewater was performed 3 times. Adsorption isotherms were analyzed using Langmuir and Freundlich models. The results showed that the best removal without recirculation occurred at a kromium concentration of 3000 ppm with a removal efficiency of 48.07%. Furthermore, recirculation was carried out 3 times and resulted in varying removal values at the 1st, 2nd, and 3rd recirculation of 37.9%, 40.06% and 35.4%. The highest removal occurred in the second recirculation. The addition of recirculation led to a decrease in the sorption of chrome as the adsorbent had reached saturation point. This allows the release of kromium ions that have been adsorbed and causes the removal efficiency to decrease. A suitable adsorption isotherm model for sludge adsorbent is the Langmuir model, where the adsorption process occurs in a single layer and is homogeneous.

Abstract

Tourism is a set of ‘machines’ that can drive the economy for regions that have tourist destinations. At present, tourism is developing according to the demands of the global market which tries to combine culture and tourism. This process is called commodification, which essentially leads to the transformation of cultural values into goods or services that have exchange value in the tourism industry. The Sarugo Village tourism area is included in the KPPK (Regency Tourism Potential Area) in Gunuang Omeh District which has cultural, religious, ecological and historical attractions. So, the development of community-based cultural tourism. This paper aims to explain the mix between culture and tourism in Sarugo Village so as to show the positive and negative effects on the culture itself or even make the culture survive. Through an ethnographic approach and data collection by observation and in-depth interviews with 15 informants, the results show that cultural aspects that are an important element in the lives of people in Sarugo Village are modified into tourism products. Rumah Gonjong is transformed into a homestay to accommodate overnight guests. This shows that the private sphere (Rumah Gonjong) turns into a public sphere in the tourism industry with the management of the local community itself. Thus, the managers of the Gonjong House, which initially only made it a place to stay, have now provided an economic increase. Therefore, the Gonjong House is currently maintained and the consequences of the tourism industry make the cultural survival of the Sarugo Village community.

Abstract

This research aims to determine the survival rate of frozen semen from Bali cattle on a liquid nitrogen surface. The research design used was a Completely Randomized Design (CRD) consisting of 5 treatments and 5 replications. The lifting and immersion treatment of frozen cement is based on the distance of the frozen cement from the liquid nitrogen surface at P0 (Control), P1 (5 cm for 5 minutes), P2 (10 cm for 5 minutes), P3 (15 cm for 5 minutes), P4 (20 cm for 5 minutes), and P4 (25 cm for 5 minutes). The variables observed were motility, survival percentage and abnormalities. The data was analyzed using variance, if it showed a significant effect, it was continued with the Duncan distance test. The results of this study found that placing frozen cement at different distances away from the liquid nitrogen surface reduced motility and survival percentage and did not affect abnormalities. Placing frozen semen from Bali cattle at a height of 15 cm or less from the surface of liquid nitrogen for 5 minutes did not reduce the quality of spermatozoa. Placing frozen Bali cattle semen as high as 20 cm or more above the surface of liquid nitrogen for 5 minutes reduces the quality of spermatozoa.
