A local focus: Implementing policies for land-use change in the Wairoa District
Authors: Smith Willie , Heath Nathan
Published: November 2021

This paper explores community attitudes to policies designed to promote increased afforestation in the Wairoa District in Northern Hawkes Bay. The approach adopted involved face-to-face interviews with over 80 local residents, including farmers and iwi representatives, as well as policy makers, land agents, forestry experts, and scientists in Hawke’s Bay and elsewhere in the country. Group meetings were also held with farmers, iwi and others in the Wairoa District. Community engagement extended from mid-2019 to early in 2020. Concerns raised about increased afforestation included its impact on employment and pastoral land use and on the provision of public services. Such concerns are grounded in some part in Wairoa’s history and traditional dependence on the hill country as the source of its identity and social well-being. Increased tree planting confronts the perceptions and experience of many land users and other community members. Resistance is heightened where the policy goals appear to conflict with economic well-being or to undermine existing values. At the same time there is evidence of a broad consensus in favour of tree planting to meet environmental needs. Current policies challenge land users’ capacity to adapt and respond to the opportunities these policies provide. Building capacity requires the provision of information and other evidence to increase understanding among all stake-holder groups
MENGELOLA CAGAR BUDAYA DI WILAYAH RAWAN BENCANA APAKAH INDONESIA SUDAH SIAP?
Authors: Rahardjo Supratikno
Published: October 2021

Bencana-bencana besar sejak lama terjadi di wilayah Indonesia. Korban-korban  nyawa, harta dan kekayaan budaya juga telah dirasakan. Namun kesadaran untuk mengantisipasi dampak bencana, khususnya  terhadap cagar budaya, belum terasa hingga memasuki awal dekade tahun 2000an. Baru sesudah terjadi bencana-bencana besar secara  beruntun selama hampir dua dekade terakhir, yaitu  tsunami, gempa bumi,  dan gunung meletus di beberapa wilayah Indonesia, upaya-upaya mitigasi bencana mulai digalakkan. Beberapa bencana yang lebih kecil skalanya namun lebih sering frekuensi kejadiannya, yaitu kebakaran dan banjir yang merusak cagar budaya, menambah kekhawatiran bahwa kekayaan cagar budaya akan semakin hilang. Pengalaman-bengalaman traumatis tersebut sebagian besar mengakibatkan kerusakan yang langsung terlihat dengan jelas. Namun sumber permasalahan lain yang tampaknya harus dijadikan prioritas justru belum disiapkan, yaitu kesadaran untuk mengatasinya melalui mitigasi agar resiko bencana dapat dikurangi dan dampak bencana dapat diminimalisasi. Tanpa melakukan upaya yang sungguh-sungguh untuk melakukan tindakan pencegahan ini bangsa Indonesia akan terancam kehilangan warisan budayanya yang sangat berharga, baik bagi generasi saat ini maupun mendatang.
BANJIR DI PEMALANG MASA KOLONIAL ABAD KE-20
Authors: Nur Utomo Ilham
Published: October 2021

Artikel ini membahas bencana banjir yang menerjang Pemalang beserta dampak yang ditimbulkan pada masa kolonial. Pemalang merupakan daerah dengan tata kota yang tidak sekompleks daerah besar lainnya, seperti Semarang atau Batavia. Namun pada tahun 1900an pembangunan infrastruktur terus dikerjakan, salah satunya sektor irigasi. Pembangunan nyatanya tidak menyelesaikan masalah banjir yang terus terjadi pada periode akhir pemerintahan kolonial pada abad ke-20. Atas dasar tersebut, terdapat dua pokok permasalahan dalam artikel ini. Pertama, menganalisis peristiwa terjadinya banjir di Pemalang. Kedua, mengkaji kompleksitas dampak yang ditimbulkan oleh bencana banjir di Pemalang. Metode yang digunakan dalam penelitian ini adalah metode sejarah, yaitu heuristik, kritik sumber, interpretasi, dan historiografi. Artikel ini menunjukkan bahwa banjir yang melanda Pemalang melanda kawasan pesisir dan dataran tinggi yang terletak di sekitar aliran sungai. Berdasar narasi yang diwartakan surat kabar kolonial, banjir yang menerjang Pemalang menimbulkan dua dampak utama. Pertama, menggenangi jalur transportasi kereta api dan post-weg, yang menghambat aktivitas distribusi ekonomi. Kedua, merusak area persawahan, menghanyutkan ternak, dan merusak rumah di sekitar daerah terdampak. Berdasar kajian ini, setidaknya menunjukkan bahwa banjir adalah bencana lintas zaman yang menimbulkan dampak negatif di bidang sosial dan ekonomi, tidak terkecuali yang terjadi di Pemalang.
GEMPA BUMI BATAVIA 1699 DAN 1780: MEMORI KOLEKTIF KEBENCANAAN
Authors: Mohtar Omar
Published: October 2021

Tujuan penulisan artikel ini adalah untuk membangkitkan kembali memori kolektif kebencanaan gempa bumi di Jakarta. Sejarah mencatat, Jakarta yang dahulu bernama Batavia pernah beberapa kali diguncang gempa bumi. Guncangan yang paling besar yang pernah mengguncang Batavia adalah gempa bumi tahun 1699 dan 1780. Gempa bumi tahun 1699 membuat kerusakan yang cukup parah. Banyak bangunan yang mengalami kerusakan akibat gempa bumi tersebut. Kondisi ini diperparah dengan rusaknya jaringan air minum dan saluran pembuangan serta kondisi cuaca Batavia saat itu yang membuat banyak orang-orang Belanda di Batavia meninggal dunia. Banyaknya orang Belanda yang meninggal membuat Batavia saat itu mendapat julukan graf der Hollanders atau kuburan orang-orang Belanda. Bencana alam yang pernah terjadi di Batavia pada masa lalu, sangat penting untuk selalu diingat. Narasi dari sejarah bencana alam, yang dalam tulisan kali ini berfokus pada gempa bumi, dapat menjadi memori kolektif pengingat bencana. Memori kolektif ini kemudian menjadi penting sebagai salah satu cara agar masyarakat yang tinggal di daerah rawan bencana gempa bumi menjadi lebih waspada terhadap bencana yang mengintai mereka. Sebagai manusia, hendaknya sesekali melihat ke masa lalu agar dapat memahami bencana yang pernah terjadi. Dengan demikian, kita dapat mengetahui potensi bencana yang mungkin akan terjadi di masa depan dan menjadi lebih siap untuk menghadapinya.

Published: October 2021

Lightweight foamed concrete brick is new construction materials. It gives a prospective solution to building construction industry, this research aims to study the cost, dead loads, environmental issues and energy consumption from using lightweight foam concrete bricks as construction materials by utilizing building information modeling technique. The results obtained from this modelling proved that the cost of brick work using lightweight foamed concrete units of grade A (2000 kg/m3) and B (1800 kg/m3 ) is higher by (19.4% and 11.9%) respectively than the activity cost using traditional fired clay bricks. For grade C (1600 kg/m3) that cost was very close to fired clay bricks (+2.9%). while the construction of brick work using light weight foamed concrete units of grade D (1400 kg/m3) and E (1200 kg/m3) was lower by (8% and 18.6%) than fired clay bricks. Besides that, the dead load generated by building units was decreased by (7.7-38.5%) for grade (B, C, D, E) than the load of fired clay bricks, while the load generated from used lightweight foam concrete bricks grade is very closed to fired clay bricks (+2.5%). There was a reduction in energy consumption by the rate of (4.1-62.2%) for heating and (9.8-73.4%) for cooling as wall sharing in energy consumption. Environmental analysis showed sustainable potential so that the production of lightweight foamed concrete units reduces CO2 emission by (46.5-67.9%) compared with the fired clay bricks. Finally; it can be concluded that building units produced in this research with LWFC, characterized with properties can efficiently compete the fired clay bricks.
Toughening of Epoxy Polysulfide Binary Blend Composite
Authors: T. Mohamed Muzher
Published: October 2021

In a composite structure, it is anticipated that high toughening can be achieved by taking advantage of mixing rubber with epoxy. The purpose of this paper is to investigate the toughness characteristics of Polymeric Composites containing Polysulfide Rubber (PSR) as a toughener to a brittle base epoxy resin. Through comparing with neat resin specimens (epoxy, epoxy +PSR), the results showed that the addition of PSR into polymeric resin enhance toughness of epoxy. Similarly experiment showed that the maximum value of mixing ration is 6% PSR, which cause a noticeable enhancement in composite strain, but a reduction in tensile strength and modulus of elasticity at fracture.

Authors: Fang Yujun , Su Xiaofang , Wang Wei , Wu Wei
Published: November 2021

The Olefin aromatization is an important method for the upgrade of catalytic cracking (FCC) gasoline and production of fuel oil with high octane number. The nano-ZSM-5 zeolite was synthesized via a seed-induced method, a series of modified nano-ZSM-5 zeolite samples with different Ga deposition amount were prepared by Ga liquid deposition method. The XRD, N2 physical adsorption, SEM, TEM, XPS, H2-TPR and Py-IR measurements were used to characterize the morphology, textural properties and acidity of the modified ZSM-5 zeolites. The catalytic performance of the Hexene-1 aromatization was evaluated on a fixed-bed microreactor. The effects of Ga modification on the physicochemical and catalytic performance of nano-ZSM-5 zeolites were investigated. The Ga species in the modified nano-ZSM-5 zeolites mainly exist as the form of Ga2O3 and GaO+, which provide strong Lewis acid sites. The aromatics selectivity over Ga modified nano-ZSM-5 zeolite in the Hexene-1 aromatization was significantly increased, which could be attributed to the improvement of the dehydrogenation activity. The selectivity for aromatics over the Ga4.2/NZ5 catalyst with suitable Ga deposition amount reached 55.4%.

We provide an algorithm to approximate a finitely supported discrete measure μ by a measure νN
corresponding to a set of N points so that the total variation between μ and νN
has an upper bound. As a consequence if μ is a (finite or infinitely supported) discrete probability measure on [0, 1]
d
with a sufficient decay rate on the weights of each point, then μ can be approximated by νN
with total variation, and hence star-discrepancy, bounded above by (log N)N−

1. Our result improves, in the discrete case, recent work by Aistleitner, Bilyk, and Nikolov who show that for any normalized Borel measure μ, there exist finite sets whose star-discrepancy with respect to μ is at most

The higher-dimensional generalization of the weighted q-adic sum-of-digits functions sq,γ
(n), n =0, 1, 2,..., covers several important cases of sequences investigated in the theory of uniformly distributed sequences, e.g., d-dimensional van der Corput-Halton or d-dimensional Kronecker sequences. We prove a necessary and sufficient condition for the higher-dimensional weighted q-adic sum-of-digits functions to be uniformly distributed modulo one in terms of a trigonometric product. As applications of our condition we prove some upper estimates of the extreme discrepancies of such sequences, and that the existence of distribution function g(x)= x implies the uniform distribution modulo one of the weighted q-adic sum-of-digits function sq,γ

HUBUNGAN NONSUICIDAL SELF-INJURY (NSSI) DENGAN ACQUIRED CAPABILITY FOR SUICIDE: STUDI META-ANALISIS
Authors: Pradipta Puti Andini , Satiadarma Monty Prawiratirta , Subroto Untung
Published: November 2021

Suicide was the third leading cause of death in adolescents in the world in 2016 with a mortality rate of about 136,000 cases. Reasons teenagers commit suicide include family financial problems, psychological distress, low self-esteem, lack of confidence, and depression. In addition, the difficulty of professional help and social support from the surrounding environment also opens up opportunities for adolescents to commit suicide. Suicidal behavior is often associated with nonsuicidal self-injury (NSSI). NSSI is an act of self-injury with no intention to commit suicide, but according to the Interpersonal Theory for Suicide by Joiner (2005), NSSI’s actions are considered to be one of the factors increasing the ability to commit suicide attempts (acquired capability). This study is aimed at exploring the relationship between NSSI and acquired capability for suicide by meta-analysis study. Eight studies from 119 articles involving the term NSSI and acquired capability were studied using the random-effects model. A total of 3398 samples were included in the study. The results showed that the effect size between NSSI and acquired capability was (r = .208), which means that NSSI is positively correlated with acquired capability and has a weak relationship. The results of this study also show that this study has a high heterogeneity value (I2 = 91,48) and there is no publication bias. Bunuh diri adalah penyebab kematian nomor tiga pada remaja di dunia pada tahun 2016 dengan angka kematian sekitar 136.000 kasus. Alasan remaja melakukan bunuh diri antara lain adalah masalah-masalah keuangan keluarga, distres psikologis, rendahnya harga diri, kurang percaya diri, dan depresi. Selain itu, sulitnya pertolongan tenaga profesional dan dukungan sosial dari lingkungan sekitarnya juga membuka peluang para remaja untuk melakukan percobaan bunuh diri. Perilaku bunuh diri sering dihubungkan dengan Nonsuicidal Self-Injury (NSSI). NSSI merupakan tindakan perusakan diri dengan tanpa adanya keinginan untuk bunuh diri, namun menurut teori Interpersonal Theory for Suicide oleh Joiner (2005), tindakan NSSI dianggap menjadi salah satu faktor meningkatnya kemampuan seseorang untuk melakukan percobaan bunuh diri (acquired capability). Penelitian ini bertujuan untuk mengeksplorasi hubungan antara NSSI dan acquired capability dengan studi meta-analisis. Delapan artikel korelasional dari 119 artikel yang melibatkan istilah NSSI dan acquired capability dipelajari menggunakan random-effect models. Sebanyak 3398 sampel dilibatkan dalam penelitian ini. Hasil penelitian menunjukkan nilai effect size antara NSSI dan acquired capability adalah sebesar (r = .208), yang berarti NSSI berkorelasi positif dengan acquired capability dan memiliki hubungan yang lemah. Hasil penelitian ini juga menunjukkan bahwa studi ini memiliki nilai heterogenitas yang tinggi(I2 = 91,48) dan tidak terdapat bias publikasi.

Slum settlement in Indonesia has been improved through various programs since before independence. The experiences of slum improvement programs show that there are still a number of challenges to perfecting them. The most critical issues have been, or related to, tenure security and the sustainability of the holistic slum management program. This research was conducted with a qualitative research approach using The Three Worlds of Action framework and a collective case study method conducted in Kel. Bintaro and Kel. Banjar of the City of Mataram. The results showed that the challenges faced at the constitutional choice level and the collective choice level, namely the policies that have been applied at the national level, have not been fully consistent and coherent with decisions at the operational choice level. This is because policies at the constitutional level are still sectoral in nature, and there is no special institution dealing with slum settlements. The second challenge is that the collective choice that has been prepared at the collective choice level has not been fully operationalized at the operational level. This is because community involvement has not been optimal from planning to implementation and the collective choice has not fully paid attention to aspects of security of residence and sustainability. Keywords: slum improvement program; The Three Worlds of Action; Kelurahan Bintaro dan Kelurahan Banjar Kota Mataram. AbstrakPemukiman kumuh di Indonesia telah ditangani melalui berbagai program sejak sebelum kemerdekaan. Pengalaman program penanganan permukiman kumuh menunjukkan bahwa masih terdapat sejumlah tantangan untuk menyempurnakan program-program dimaksud. Beberapa di antaranya terkait kepastian bermukim dan keberlanjutan program penanganan permukiman kumuh yang holistik. Penelitian ini dilakukan dengan pendekatan penelitian kualitatif dengan menggunakan kerangka kerja The Three Worlds of Action dan metode studi kasus kolektif yang dilakukan di Kel. Bintaro dan Kel. Banjar Kota Mataram. Hasil penelitian menunjukkan bahwa tantangan yang dihadapi pada tingkat pilihan konstitusional dan tingkat pilihan kolektif, yaitu kebijakan yang telah diterapkan di tingkat nasional, belum sepenuhnya konsisten dan koheren dengan keputusan di tingkat pilihan operasional. Hal ini disebabkan karena kebijakan di tingkat konstitusi masih bersifat sektoral, dan belum ada institusi khusus yang menangani permukiman kumuh. Tantangan kedua, pilihan kolektif yang telah disusun pada level pilihan kolektif belum sepenuhnya dioperasionalkan pada level operasional. Hal ini dikarenakan pelibatan masyarakat belum optimal dari perencanaan hingga pelaksanaan dan pilihan kolektif belum sepenuhnya memperhatikan aspek keamanan bertempat tinggal dan keberlanjutan.

Petrological and geochemical analysis of the ultramafc-mafc intrusions of the Noril’sk province ranks them into three types in terms of sulphide mineralization style and economic signifcance: 1) economic intrusions containing unique and large sulphide PGE-Cu-Ni deposits (Oktyabr’sk, Talnakh and Noril’sk-1); 2) subeconomic intrusions that contain small- to medium-sized Cu-Ni sulphide deposits, and medium-sized to large PGE deposits (Chernogorsk, Zub-Marksheider, Vologochan, etc.); 3) uneconomic intrusions that contain low-grade disseminated Cu-Ni ores with ≈0.2 wt % of Cu and Ni, and low Cr and PGE (Nizhny Talnakh, Zelyonaya Griva, etc.). Results and conclusions. Principal sources used in exploration for rich sulphide PGE-Cu-Ni ores include structural, magmatic, stratigraphic-lithological, geochemical, mineralogical, metamorphic and some others. Based on an analysis of isotope-geochemical data, new indicators for locating sulphide PGE-Cu-Ni mineralization are suggested. A restricted range of S-isotope values, and a negative trend for coupled S-Cu isotope compositions can be employed as useful guides to assess the economic potential of a PGE-Cu-Ni sulphide deposit. It is proposed that the Chernogorsk ultramafc-mafc intrusion of the Noril’sk province is the most promising target in a search for rich PGE-Cu-Ni ores. It is suggested that the previously known mineralogical-geochemical and novel isotope-geochemical characteristics of sulphide and silicate minerals are important indicators in assessing the potential ore content of ultramafc-mafc intrusions of the Noril’sk province.
THE CONCEPT OF THE ARCHIPELAGIC PROVINCE AND ARCHIPELAGIC STATE IN THE PERSPECTIVE OF NATIONAL AND INTERNATIONAL LAW
Authors: Risnain Muhammad
Published: November 2021

The concept of an archipelagic province in law number 23 of 2014 is interesting, especially international law of the sea and Indonesian national law. This research is due to the concept of an archipelagic State's special treatment, which is a concept derived from the 1982 United Nations Convention on the Law of the Sea (UNCLOS). This research accommodates the state's interests with special conditions for States that are geographical, social, political, and economic conditions by fulfilling the 1982 UNCLOS. The state is a subject of the international, but the archipelagic province receives special treatment from the central government in DAU and DAK. The problem in this research is how the concept of an archipelagic province and state is based on national and international law? The research method used is normative juridical research based on the applicable laws and regulations. The analysis is carried out using a descriptive method that explains the concept of an archipelagic province and state from the perspective of national and international law. The archipelagic state's international and national law concept cannot be applied to mutatis mutandis. The criteria for an archipelagic state as an intrinsic geographical, economic, defense and security, and political unit have historically been regarded as such. The 1982 UNCLOS and national laws cannot be applied in determining the criteria for an archipelagic province. According to the elucidation of Law Number 23 of 2014 concerning regional government, the archipelagic province based on geographical and cultural conditions is a moderate concept. This concept is beneficial in determining the characteristics of an archipelagic province.

The study aims to determine the productivity of elephant grass cv Taiwan (Pennisetum purpureum cv Taiwan) from gamma ray irradiation at a dose of 50 gy at five harvest in one year. The study used a randomized block design (RBD) with 3 replications, the treatment was 51 numbers clone of elephant grass (P. purpureum cv Taiwan) from gamma ray irradiation and control (without irradiation). Observations were made on each number of elephant grass irradiated on 5 plants per number, and were made on 10 plantswith a harvest interval of 2 months. The observed parameters include the number of tillers; fresh and dry leaf weight; fresh and dry stem weight, and total weight. The results showed a significant impact of gamma radiation (P<0.05) on tiller count, fresh leaf weight, dry leaf weight and fresh stem weight as well as dry stem weight and total weight. These results show that gamma radiation on elephant grass can generate diversity and increase its productivity. The best cuttings can be made on the fourth cut in clones no. 19, 1, 27, 31 and 3.

Published: November 2021

The article presents results of studying and manufacturing environmentally friendly alkyd paint. By producing a polysaccharide intermediate emulsion (LPR), about 20% of water to total paint volume was added. Mechanical properties (impact resistance, flexural strength, adhesion) of paint films were studied. In addition, the paper presents results of thermal stability, 10-cycle UV-thermo-humidity complex stability of paint film. Ability of films to withstand 03-cycle heat shocking of films at temperatures of + 50 oC and -50 oC was investigated. The properties of studying paint were compared with those of an alkyd paint of Hanoi Synthetic Paint Company. Results show that the environmentally friendly alkyd paint has less volatile organic compounds (VOC), uses a smaller amount of toxic solvents, while its properties are comparable to common alkyd paint.

Aim: The aims of this research is to determine the ability of an indigenous microbial consortium to degrade Low Density Polyethylene plastics. The plastic was cut mechanically into 1 x 1 cm2 pieces because the smaller the size of the plastic, the larger the surface area. The samples are input in an Erlenmeyer flask containing indigenous microbial consortium and fungi (20% v/v) and Stone Mineral Salt solution media (80% v/v). This research lasted 10 days with a pH of 7 controlled and temperature variations of 25, 30, 35°C. As preliminary research, the sensitivity test seeks to demonstrate that the indigenous microbial consortium and fungi are resistant or insensitive to LDPE. The degradation of LDPE plastic was analyzed using gravimetric methods, Fourier Transform Infrared, and a scanning electron microscope. Methodology and results: According to the results of gravimetric and FTIR analysis, the highest removal value was at a temperature variation of 30°C. The gravimetric analysis revealed that the weight loss in LDPE plastic was 0.0082 gr to 0,0074 gr or 9.76 %, while the FTIR analysis revealed that the intensity removal result was 6,27 %. Conclusion, significance, and impact of study: Scanning Electron Microscope (SEM) analysis revealed morphological changes on the surface of LDPE plastic samples, confirming these findings. Several factors influence the changes that occur in this study's LDPE plastic samples.

Statement of the problem. The problem of athletes’ performance recovery is most significant due to the increased sports loads for athletes. The sport of high achievements requires huge physical and emotional strength from the athlete, while the load increases. The history of the latest sports competitions proves that the load for athletes is growing. The growth of loads initiates the development of recovery tools, tools that allow athletes to maintain their shape. The use of modern tools and methods of recovery increases the potential of an athlete at the stage of sports skills improvement. It should be noted that there are very few publications devoted to new recovery tools for athletes. In this regard, this article has a special relevance. The purpose of the article is to characterize the recovery tools of track-and- field athletes (race walkers) at the stage of their sports skill improvement. The research methodology consists of an integrated approach, a generalization method, analysis of special literature on the research problem, and content analysis. Research results. The analysis made it possible to conclude that it is necessary to increase attention to the development of the methodology and technique of recovery of a track-and-field athlete. At this time in sports, the problem of recovery is important, as is training. Consequently, the methods of restoring and relieving fatigue in an athlete are of paramount importance in the modern world. A characteristic feature of sports is training loads of significant intensity and volume, which make high demands on the body of athletes. The search for the most effective means of recovery makes it possible to increase the ability of the body. Conclusion. Improving methodological and analytical tools for the recovery process of athletes is an important and urgent problem that has not been solved methodically and methodologically. In modern conditions, it is necessary to create a model for working with an athlete, where the athlete’s recovery process will be based on a scientific approach using innovative tools.
