Purpose The purpose of this paper is to analyze the relationship between Job Design, Job Commitment and Organizational Culture with Human Resource Performance: a study of the construction services provided by national consultants. Design/methodology/approach The research population consisted of all employees of a national company offering consultation services, from four big Indonesian State-Owned Enterprises Contractors: PT. Yodya Karya Company, PT. Hutama Karya, PT. Adhy Karya, PT. Waskita Karya Referring to the approach to SEM modeling with an average population of 600 employees for each enterprises, the sample to be used as respondents consisted of 100 employees for each enterprises, and total 100×4 enterprises=400 samples. Findings The variables Organizational Culture and Job Design have a significant direct effect on Job Commitment. Likewise, the effect of Organizational Culture and Job Commitment on Human Resource Performance is also significant. However, a different result is shown in the result of the direct effect of the variable Job Design on the variable Human Resource Performance, which indicates that the variable Job Design does not have a significant direct effect on the variable Human Resource Performance. In other words, the intensity of the Job Design value will not affect the intensity level of Human Resource Performance. In addition, a mediating effect of the variable Job Commitment is found on the effect of Job Design and Organizational Culture on Human Resource Performance. Originality/value The use of Job Commitment to exercise a mediation effect on the relationship between the effect of Job Design and Organizational Culture on Human Resource Performance, and the research site (no previous research investigating this relationship).

Purpose The purpose of this paper is to know the effect of mediation of work motivation on the influence of job design and organizational culture on human resource performance. Design/methodology/approach The design of the study is the detailed planning used as a study guide that leads to the purpose of the study. The unit of analysis of this research is the expert and skilled labor of construction service actors working in the national consulting company PT. Yodya Karya (Persero) at the central level and branches spread over 11 branches in Indonesian territory. Data analysis method used is path analysis and Sobel test to test the indirect effect (mediation effect). Findings Based on the results of the analysis, several things can be concluded such as: there is a significant direct influence of work design on the performance of human resources and work motivation; there is a significant direct influence of organizational culture on work motivation and human resource performance; and there is a significant direct influence of work motivation on human resource performance. There is an indirect influence of work design on the performance of human resources through work motivation mediation variables. Meanwhile, work motivation is not the influence of organizational culture on human resource performance. Originality/value The originality of this research lies in forming the mediator variable that is the work motivation on the causal relationship of two variables and adding new variables of work design on the effect on the human resource performance.

BackgroundThe HIV prevalence among injecting drug users (IDUs) in Indonesia reached 50% in 2005. While drug use remains illegal in Indonesia, a needle and syringe program (NSP) was implemented in 2006.MethodsIn 2007, an integrated behavioural and biological surveillance survey was conducted among IDUs in six cities. IDUs were selected via time-location sampling and respondent-driven sampling. A questionnaire was administered face-to-face. IDUs from four cities were tested for HIV, syphilis, gonorrhoea and chlamydia. Factors associated with HIV were assessed using generalized estimating equations. Risk for sexual transmission of HIV was assessed among HIV-positive IDUs.ResultsAmong 1,404 IDUs, 70% were daily injectors and 31% reported sharing needles in the past week. Most (76%) IDUs received injecting equipment from NSP in the prior week; 26% always carried a needle and those who didn’t, feared police arrest. STI prevalence was low (8%). HIV prevalence was 52%; 27% among IDUs injecting less than 1 year, 35% among those injecting for 1–3 years compared to 61% in long term injectors (p < 0.001). IDUs injecting for less than 3 years were more likely to have used clean needles in the past week compared to long term injectors (p < 0.001). HIV-positive status was associated with duration of injecting, ever been imprisoned and injecting in public parks. Among HIV-infected IDUs, consistent condom use last week with steady, casual and commercial sex partners was reported by 13%, 24% and 32%, respectively.ConclusionsAlthough NSP uptake has possibly reduced HIV transmission among injectors with shorter injection history, the prevalence of HIV among IDUs in Indonesia remains unacceptably high. Condom use is insufficient, which advocates for strengthening prevention of sexual transmission alongside harm reduction programs.

BACKGROUND: Stunting remains a nutritional problem in children in Indonesia and some other developing countries. It has become a public health problem that must be taken seriously and continuously. Although there was an improvement in 2018, the incidence of stunting in Indonesia is still quite high (36.4%), compared to other Southeast Asian countries such as Malaysia (20%) and Thailand (10.5%). In the world, Indonesia occupies the 17th position of 117 countries for the stunting incidence. AIM: This study aims to describe the risk factors of stunting in children under five in developing countries. METHODS: This research is a scoping review. The sources were drawn from multiple databases such as Ebsco, PubMed, ProQuest, and Science Direct with the keyword “stunting” AND “risk factors” AND “developing countries.” Inclusion criteria include the research must be related to the risk factors of stunting, should be conducted in developing countries, should be full texted in English, and published in 2015–2019. RESULTS: The search of databases found 3605 articles, with the details of 10 articles from Ebsco, 45 articles from PubMed, 20 articles from ProQuest, and 3530 articles from Science Direct. According to all the databases, only 9 articles were reviewed that met the inclusion criteria of this study. CONCLUSION: Parent factors, toddler factors, and environmental factors are risk factors of stunting in children under five.

Education is one way to prepare the next generation of quality nations. The magnitude of the marine territory of Indonesia must be balanced with the next generation who have the high marine life. This is in contrast to the fact that the people of Untung Jawa island have not shown their concern and care to provide targeted marine education as a form of social responsibility in preparing the maritime generation in its territory, the school education institution (especially SD Negeri Untungjawa) has not been structured and programmed to provide marine education as part of the implementation of the Curriculum 2013, especially on curriculum diversification in accordance with geographical conditions, advantages and disadvantages of the institution. This research is an R & D research that aims to develop an integrative thematic model of project-based learning in implementing maritime education on elementary school students in the Thousand Islands, DKI Jakarta. This project-based integrative thematic conceptual learning model is expected to be an alternative and contribute to implement marine education from early years.   Key Word: Integrative thematic learning, project learning, marine education   Pendidikan menjadi salah satu cara untuk mempersiapkan generasi penerus bangsa yang berkualitas. Besarnya wilayah kelautan Indonesia harus diimbangi dengan generasi penerus yang memiliki jiwa kelautan yang tinggi. Hal ini bertolak belakang dengan fakta yaitu warga masyarakat pulau Untung Jawa belum ada yang menunjukkan perhatian dan kepeduliannya untuk memberikan pendidikan kelautan yang terarah sebagai bentuk tanggung jawab sosial dalam mempersiapkan generasi maritim di wilayahnya, lembaga pendidikan sekolah (khususnya SD Negeri Untungjawa) belum secara terstruktur dan terprogram memberikan pendidikan kelautan sebagai bagian dari pelaksanaan Kurikulum 2013, terutama pada diversifikasi kurikulum sesuai kondisi geografis, keunggulan dan kelemahan yang dimiliki lembaga. Penelitian ini merupakan penelitian R&D yang bertujuan untuk mengembangkan model pembelajaran tematik integratif berbasis proyek dalam mengimplementasikan pendidikan kelautan pada siswa SD kelas awal di kepulauan Seribu, DKI Jakarta. Model konseptual pembelajaran tematik integratif  berbasis proyek ini diharapkan  dapat dijadikan alternatif dan memberikan kontribusi untuk mengimplementasikan pendidikan kelautan sejak usia dini.   Kata Kunci: Pembelajaran tematik integratif,  proyek, pendidikan kelautan.

It is important to develop a renewable source of energy to overcome a limited source fossil energy. Palm oil is a potential alternative and environmental friendly energy resource in Indonesia due to high production capacity of this vegetable oil. The research studied effect of catalyst to selectivity of biofuel product from cracking of palm oil. The catalyst consisted of HZSM-5 catalyst with or without impregnation. The research was conducted in two steps, namely catalyst synthesized and catalytic cracking process. HZSM-5 was synthesized using Plank methods. The characterization of the synthesized catalysts used AAS (Atomic Absorption Spectroscopy) and BET (Brunaueur Emmet Teller). The cracking was carried out in a fixed bed microreactor with diameter of 1 cm and length of 16 cm which was filled with 0.6 gram catalyst. The Ni/HZSM-5 catalyst was recommended for cracking palm oil for the high selectivity to gasoline.

This study is qualitative research that aims to describe and analyze the students’ learning difficulties in mathematical operations of negative integers. The subjects of the study were two students of 286 SDN 286 Pasaka. Giving test (diagnostic tests) and interviewing were conducted to collect the data. The results of the study show that basically the learning difficulties experienced by the subject IS and subject RV is the same: the lack of understanding of the concept of negative integer operations. Due to the lack of understanding of the concept, the subject is difficult to abstract, generalize and remember the concept or principle of operating negative integer operations. To overcome the learning difficulties experienced by students, the teacher must ensure students have mastered the prerequisite material, design ways of delivering teaching materials with effective communication and pay attention to family circumstances and social conditions of students.Keywords: Characteristics of items, item difficulties, discrimination
