Published: September 2018

Summary An experiment has been conducted to study the effect of sludge concentration, waste of paper industry using raw material of recycled paper, as media on oyster mushroom production and quality. Twelve treatment tested are combination of two oyster mushroom strains are oyster mushroom of Bogor (JTB) and oyster mushroom of Taiwan (JTT), three media composition (sawdust, sludge, and sawdust+ sludge (50/50, v/v), and two levels of supplement addition (with rice bran+gypsum+ lime and without) with 10 replications. The production of the mushroom was conducted in bag log capacity of 1 kg fresh weight (water content 50%). The result showed that sludge can be used as mixture of oyster mushroom production with the composition 50:50 v/v of sawdust and sludge. Since the higher number of contamination, addition of supplement reduce oyster mushroom production as well as biological efficiency, but increased protein content of fruiting body. The content of Cd, and Pb were below the permissible limits, Cu was higher than the limits but still in the range. The Fe content of mushroom fruit body was higher both in sawdust (147.92 – 149.56 ppm) and sawdust+sludge (295.82 – 335.12 ppm) as media. However, the uptake of Fe of JTT was less (49.08-59.64 ppm) compared to that of JTB (147.92-335.12 ppm).Ringkasan Penelitian dilakukan untuk mempelajari pengaruh konsentrasi sludge limbah pabrik kertas berbahan baku karton bekas sebagai medium terhadap produksi dan kualitas jamur tiram. Dua belas perlakuan yang diuji merupakan kombinasi dua galur jamur tiram, yaitu Jamur Tiram Bogor (JTB) dan Jamur Tiram Taiwan (JTT), tiga jenis komposisi medium (serbuk gergaji, sludge, dan sludge+ serbuk gergaji), dan dua tingkat suplemen (dengan dan tanpa) yang diulang 10 kali untuk masing-masing perlakuan. Produksi jamur tiram dilakukan menggunakan bag log berkapasitas 1 kg basah (kadar air 50%). Hasil percobaan menunjukkan bahwa sludge dapat digunakan sebagai campuran serbuk gergaji dalam produksi jamur tiram dengan per-bandingan 50:50 (v/v). Pemberian suplemen menurunkan produksi jamur tiram demikian pula efisiensi biologi namun meningkatkan kadar protein tubuh buah. Di dalam tubuh buah JTB, kandungan logam Cd, dan Pb berada di bawah batas yang diijinkan, sedangkan kandungan Cu di atas ambang walaupun masih dalam kisaran. Kandungan Fe dalam tubuh buah jamur relatif tinggi baik yang ditumbuhkan pada serbuk gergaji sebagai medium standar (147,92 - 149,56 ppm) maupun yang ditumbuhkan pada medium campuran sludge+serbuk gergaji (295,82 - 335,12 ppm). Serapan Fe tubuh buah JTT jauh lebih rendah (49,08- 59,64 ppm) dibandingkan dengan serapan Fe JTB (147,92-335,12 ppm).

AbstractSoil aggregation is a dynamic and very important factor for the development of agricultural soil functions. Unstable soil aggregation in a sandy soil type is a limiting factor for plant growth. The aim of this study was to investigate theinfluence of a exopolysaccharide-producing bacterium and organic material on some physical properties of a sandy soil. A highly potential bacterium for exopolysaccharides production, i.e Burkholderia cenocepacia, was isolated froma sandy soil located at Kotawaringin Barat, Central Kalimantan. The isolated bacterium is capable on improving aggregate’s stability of a soil with about 60% sand fraction [medium sand fraction (MSF)]. Interaction between available water and electric conductivity with aggregate stability index has significant correlation in medium sand fraction inoculated by 109 CFU of B. cenocepacia suspension, i.e. r = 0.806* and r=0.966**, respectively. Organic materials and its combination with the addition of 108 CFU B. cenocepacia suspension treatments could increase the aggregate stability index but have no effects on bulk density and total pore space values in an artificial condition of medium sand fraction. AbstrakAgregasi tanah bersifat dinamis dan merupakan faktor penting untuk pengembangan fungsi tanah pertanian. Ketidakstabilan agregat tanah pada jenis tanah berpasir merupakan faktor pembatas untuk pertumbuhan tanaman.Penelitian ini bertujuan untuk mengetahui pengaruh eksopolisakarida bakteri dan bahan organik terhadap beberapa sifat fisik bahan tanah berpasir. Satu bakteri potensial penghasil eksopolisakarida yaitu Burkholderia cenocepacia telah berhasil diisolasi dari bahan tanah berpasir asal Kotawaringin Barat, Kalimantan Tengah. Bakteri ini dapat meningkatkan kemantapan agregat bahan tanah dengan kandungan fraksi pasir sekitar 60% [fraksi pasir sedang (FPS)]. Hubungan antara air tersedia dan konduktivitas elektrik terhadap indeks kemantapan agregat sangat nyata pada bahan tanah FPS yang diinokulasi dengan 109 CFU suspensi B. cenocepacia masing-masing r = 0,806* dan = 0,966**. Perlakuan bahan organik dan kombinasinya dengan penambahan 109CFU suspensi B. cenocepacia dapat meningkatkan indeks kemantapan agregat tetapi tidak mempengaruhi nilai kerapatan lindak dan total ruang pori di dalam fraksi pasir sedang.

Abstract Alkaline pretreatment of oil palm empty fruit bunch (EFB) fiber was conducted to improve enzymatic sacchari-fication of EFB fiber for ethanol production. EFB as one of the major biomass wastes from palm oil industry is a complex lignocellulosic material consists of 41.3 – 46.5% of cellulose, 25.3 – 33.8% of hemicellulose and 27.6 – 32.5% of lignin. Alkali pretreatment of EFB using NaOH 1 N with temperature at 30 and 600C and reaction times of 30, 60, 90, 120 and 150 minutes were investigated. Furthermore, the enzymatic saccharification of pretreated EFB was examined. The pretreated substrate was subjected to an enzymatic saccharification using meicelase (10, 20 and 40 FPU/g substrate) at 400C, pH 4.5, 100 rpm for conversion of cellulose and hemicellulose in palm oil EFB to monomeric sugars. The alkali pretreatment of EFB using NaOH can significantly improve the enzymatic saccharification of EFB by removing more lignin and hemicellulose and increasing its accessibility to hydrolytic enzymes. The results showed that the optimum pretreatment condition was NaOH 1 N at 300C and 90 minutes with the optimum component loss of lignin and hemicellulose was 45.8 % and 35.6 % respectively. The saccharification of EFB pretreated by NaOH 1 N (at 300C and 90 minutes) for 45 hours and pH 4.5 resulted in optimum saccharification of 63.8 %. Abstrak Pengolahan awal (pretreatment) serat tandan kosong kelapa sawit (TKKS) dengan basa NaOH telah dilakukan untuk meningkatkan sakarifikasi enzimatik TKKS menjadi etanol. TKKS merupakan bahan lignoselulosa yang terdiri dari selulosa 41,3– 46,%, hemicellulosa 25,3 – 33,8% dan lignin 27,6 – 32,5%. Pretreatment TKKS dilakukan dengan NaOH 1 N dengan variasi suhu 300 dan 600C dan variasi waktu 30, 60, 90, 120 dan 150 menit. Konversi selulosa dan hemiselulosa hasil pretreatment TKKS menjadi gula dilaku-kan dengan sakarifikasi enzimatik menggunakan enzim meiselase (10, 20 dan 40 FPU/g substrat) pada suhu 400C, pH 4,5 dengan shaker 100 rpm. Pretretament TKKS dengan basa NaOH dapat meningkatkan sakarifikasi enzimatik dengan berkurangnya lignin dan hemiselulosa secara signifikan dan memudahkan masuknya enzim hidrolitik. Hasil pretreatment dengan NaOH 1N pada suhu 300C dan 90 menit menunjukkan kondisi optimum untuk penghilangan lignin dan hemiselulosa berturut-turut sebesar 45,8 % and 35,6 %. Hasil sakarifikasi optimum yaitu 63,8 % dicapai setelah 45 jam sakarifisi pada pH 4,5.

Abstract White-rot fungi (WRF) are belong to Basidiomycetes group that capable to degrade lignin, because they produce extracelullar ligninolytic enzymes such as lignin peroxsidase (Li-P), mangan peroxidase (Mn-P) and laccase. The ligninolytic activity can be used in bioprocess oxidation system such as biopulping, biobleaching and bioremediation. The purposes of this research were to determine the optimum conditions of growth and ligni-nolytic activity of Omphalina and to observe its potential to decolorize cosmetics wastewater. Omphalina sp. was grown on media of PDA-Remazol Brilliant Blue R (RBBR) and PDA-Guaiacol (GU) at various pH and temperature conditions. The decolorization of cosmetic effluent was conducted by applying Omphalina sp. at various dose of inoculum. Decolorization rate and change of COD were observed for eight days. The results showed that Ompha-lina sp. could grow and produce peroxidase enzyme both on RBBR and GU media at pH 4.5-8.5 and temperature 23-350C. Optimum dose of inoculum was as much as 5% w/v at which the fungus was able to decolorize cosmetic factory effluent up to 92.79% and to decrease COD value up to 48.57 % after eight days of incubation.Abstrak Jamur pelapuk putih (JPP) merupakan jamur kelompok Basidiomycetes yang mampu mendegradasi lignin karena memproduksi enzim-enzim ligninolitik ekstraseluler seperti lignin peroksidase (Li-P), mangan peroksidase (Mn-P) dan lakase.

Authors: Cundell Alicia , Sheepy Emily 
Published: September 2018

The principal concern of this research was to learn more about effective designs of learning activities in blended courses. A questionnaire was administered in three sections of a not-for-credit intensive blended graduate seminar in university teaching. The online activities included readings, videos, discussion forum activities and other activities using a range of web-based technologies. Students rated each of the activities on four target criteria: alignment with the course learning outcomes, deep learning, engagement, and value. Students also were asked to identify the most useful activities for each of the five modules and evaluate the course as a whole in terms of navigation, expectations, instructions, availability of materials, instructor presence, and technical quality of media. The results suggest that students’ perceptions of the activities followed very similar patterns across the four target criteria. The most highly-rated activities had four distinct design, which are discussed.

This exploratory study examines student tagging activity within a five-week social bookmarking unit. Students in six sections of a course were tasked with locating, tagging, and then highlighting and discussing course-related materials using Diigo, a social bookmarking tool. Three different tagging approaches were tested: dictionary only, freestyle only, and dictionary + freestyle. Analysis focused on accuracy and rates of student tagging, popularity of different tag types Findings show that most students were able to tag with high rates of accuracy after a single brief lesson. The dictionary-only approach led to fewer tags overall as well as fewer single-use tags than freestyle tagging. It also resulted in students applying useful classes of tags, such as type of content, that did not emerge within the freestyle tag groups’ folksonomies. However, freestyle tagging was not without its merits, and provided opportunities for students to include tags that reflect relevant interests and more specific topics that were not addressed in the tag dictionary. The combined approach, if carefully taught and applied, appears to have the greatest potential for supporting student information literacy skills.

PERLINDUNGAN HUKUM TERHADAP KELOMPOK AGAMA MINORITAS DALAM HUKUM PIDANA INDONESIA
Authors: Sumika Putri Nella 
Published: September 2018

Criminal law should provide protection to all citizens (individually or communities) without regard to their ethnicity, race or religion. In addition, it is also important that its implementation should be done non-discriminatively. This research is done using a normative juridical approach. The most important finding is that a number of penal regulations (inter alia, prohibiting blasphemy, genocide or in the criminal code draft relating to extra-marital sex) in its implementation and enforcement results in discrimination or even worse persecution of minority groups. The author here argues that, in order to guarantee the principle of equal treatment before the law and protection of (religious) minority groups, those penal regulations should be harmonized and read within the context of other existing penal rules.

This article is the result of an explorative study on methodological issues in Indonesian legal science. It uses a literature review to trace current debate on three interrelated issues concerning legal scholarship, legal development and legal pluralism. Each of these issues will be juxtaposes to contemporary legal discourse. Separately the issue of legal scholarship will be just apose to the praxis of legal research methodology and legal education; legal development to “law and development” paradigm; legal pluralism to rule of law. The author follows the legal thinking tradition employed by influential legal scholars: Paul Scholten, Soediman Kartohadiprodjo and B. Arief Sidharta. The standing of other prominent legal authors such as Mochtar Kusuma-Atmadja and Soetandyo Wignyosoebroto, to the extent that their ideas are relevant to this article, will be briefly discussed.

There is a need to conduct business transactions rapidly and in a quick perfunctory manner. At the same time arose also the need to develop and implement a quick, simple and cost efficient business dispute settlement procedure. In response to this need, the Indonesian Supreme Court issued regulation no. 2 of 2015 re. procedure for filing simple civil claims. The legal issue to be discussed here, using a juridical normative or dogmatic approach, is whether this regulation succeed in fulfilling its promise to provide for a quick, simple and cost efficient civil claim examination procedure? The answer to this question is sought, in addition to the method mentioned above, by comparing the procedure provided by the Supreme Court regulation with the existing model of civil claim court examination procedure. By virtue of this comparison the strength and weakness of the Supreme Court dispute settlement model can be analyzed.

The right to health is widely recognized as basic human rights and consequently it is the state’s duty to guarantee its fulfilment. The Indonesian government, in realization of this duty, develops and put in place a national health care (insurance) system, which successful working depend on citizens paying equal amount of the premium needed to sustain this public health care system. However, the same state, in the context of social justice and welfare, provide poor citizens with monetary aid. This article discusses, by using a juridical normative approach, supplemented by an inter-multi disciplinary approach, the political dynamics underpinnings influencing the social or health care system’s implementation.

This paper discusses the issue of refugees from an international law perspective. It is known that Indonesia is not a party to either the 151 Refugee Convention as well as the 1967 Protocol, but mostly as transit country house a number of refugees running away from conflict areas in Myanmar, the Middle East and Afghanistan. This legal research employs a juridical normative method. By tracking down and analyzing all relevant legal sources it is revealed that Indonesia’s treatment of refuges is based on the general obligation to protect and honor human rights (on the basis of international minimum standard). It is further recommended that Indonesia should actively support the global compact on refugees.
AGITASI DAN PROPAGANDA DI MEDIA SOSIAL (Studi Kasus Cyberwar Antar-Netizen terkait Dugaan Penistaan Agama oleh Basuki Tjahaja Purnama)
Authors: Malik Abdul 
Published: September 2018

Media sosial facebook saat ini lebih dominan dimanfaatkan sebagai ajang untuk membangun dan menyebarkan pesan maupun wacana-wacana kebencian. Dugaan penistaan agama oleh Basuki Cahaya Purnama Alias AhokÂ saat melakukan kampanye sebagai calon gubernur DKI di Kepulauan Seribu, adalah contoh kasus yang menimbulkan kegaduhan di ruang maya. Polemik atas kasus tersebut menunjukkan bahwa kebebasan berkomunikasi di dunia maya lebih cenderung destruktif daripada bersifat konstruktif yang disebabkan oleh komentar baik berupa ujaran maupun wacana para netizen yang tanpa disertai oleh kesadaran etis.Â Belajar dari kasus ini, maka semangat demokratisasi melalui ruang cyber sebagaimana menjadi harapan banyak pihak pada masa-masa awal kemunculannya justru bertolak belakangan dengan fakta yang kerap muncul ranah ini. Sehingga alih-alih menjadi saluran bagi tersemainya semangat demokratisasi antar-anggota masyarakat (netizen), yang terjadi adalah bahwa ketiadaan gatekeeper telah menjadikan media sosial seperti facebook sebagai saluran yang bebas nilai dan tempat tumbuhsuburnya berbagai ujaran dan wacana kebencian yang berimplikasi pada redupnya semangat demokratisasi itu sendiri.
