Drill and Blast Performance Evaluation at the Obra Pit of Chirano Gold Mines Ltd, Ghana
Authors: Eshun P. A. , Affum B. O. , Boakye A. 
Published: April 2021

This paper investigates the causes of inefficient fragmentation and formation of toes in the Obra pit of Chirano Gold Mines Ltd and recommends best practices in order to produce optimum fragmentation to feed the crusher at a reduced cost and to provide good working pit floors. The methods employed included: drilling performance analysis using statistical methods; fragmentation analysis of blasting performance using Kuz-Ram Model and Wipfrag software; determination of the velocity of detonation of the bulk explosive using MREL Micro Trap VOD/Data Recorder; and estimation of the cost of secondary drilling and blasting using Mine Management Reporting Software. From the analyses, it was observed that the blast designed parameters and blasting practices were acceptable to produce good fragmentation but the actual drilling parameters deviated from the designed parameters by about 25%, 24% and 26% in hole depth, burden and spacing respectively. It was concluded that the cause of the ineffective fragmentation leading to high cost of secondary breakage and uneven pit floors was due to operational errors during drilling. It is therefore recommended that in order to reduce excessive deviations in the drilling parameters, periodic training of operators must be conducted, supervision of drilling and blasting operations must be enhanced, and inclinometers should be used during drilling activities to ensure the accuracy and precision of all blast holes. Keywords: Drilling, Blasting, Fragmentation, Kuz-Ram Model, Wipfrag Software
Siltation of Ore Particles in Leaching Tanks: Causative Factors and Mitigation Measures
Authors: Osei R. , Abaka-Wood G. B. , Ofori-Sarpong G. , Amankwah R. K. 
Published: April 2021

Siltation involves the accumulation of sediment over a considerable period of time and this may occur in closed systems like leaching tanks. Most mining companies in Ghana experience siltation problems during leaching of gold ore. This paper examines the potential causes and possible mitigation measures of siltation. Particle size analysis, slurry settling rate tests and agitation efficiency analysis were used in identifying causative factors of siltation whiles deflocculation test and grind analysis were conducted to ascertain mitigation measures. Results from the study indicated that, high settling velocity of particles, inefficient milling and classification, poor slurry agitation and particle flocculation were the major causative factors leading to siltation. Size analysis results revealed P67 of 106 µm instead of P80 of 106 µm, a situation which affects particle suspension by agitators leading to siltation. This study therefore suggests that increase in milling residence time and particle deflocculation are potential remediation measures for curbing siltation. Extended grinding of ball mill feed resulted in 94% passing 106 µm while settling velocity was reduced by 71% after deflocculant addition at 1000 ppm. Keywords: Siltation, Deflloculation, Settling Velocity, Grinding
Mapping the Effects of Anthropogenic Activities in the Catchment of Weija Reservoir using Remote Sensing Techniques
Authors: Tagoe N. D. , Mantey S. 
Published: April 2021

Man has contributed to land cover alteration since time-immemorial through clearing of land for residential, agriculture, recreational and industrial purposes. The emergence of adapting wild plants and animals for human use as well as industrialisation have also contributed to the alteration of land cover. Over the years, anthropogenic activities have had great impact on the Weija catchment. This study seeks to map the catchment and determine the impact of anthropogenic activities using Remote Sensing techniques. Observations and measurements were made on the field as well as classification of land cover using Landsat images of years 1991, 2003 and 2017. Results showed an increase in built-up areas by 18% from 1991 to 2017. Other classes such as shrubs increased due to decrease in dense vegetation. This study confirms the use of Remote Sensing as a valuable tool for detecting change in land cover and determining the impact of anthropogenic activities in the Weija Catchment.

Authors: Adeyemo Igbagbo Adedotun , Olumilola Olumide Abiola , Ibitomi Michael Adewale 
Published: April 2021

Fifty two vertical electrical sounding (VES) data and six subsurface soil samples were collected at Ondo State Industrial Layout, Akure, south-western Nigeria in order to determine the subsurface corrosivity. The VES results delineated 3 to 5 geoelectric layers across the area, which correspond to topsoil, weathered layer, weathered basement, weathered/fractured basement and the presumed fresh bedrock. The layer resistivity values range from 22 to 602 ohm-m, 7 to 2468 ohm-m, 17 to 436 ohm-m, 25 to 39 ohm-m and 203 to 10023 ohm-m in the topsoil, weathered layer, weathered basement, weathered/fractured basement and the presumed fresh bedrock respectively. The iso-resistivity maps at depth slices of 1 and 2 m show that the northeastern, southeastern and the upper central part of the area are non-corrosive (above 350 ohm-m) to slightly corrosive (250 - 350 ohm-m), while the lower central, northwestern and southwestern parts of the area are moderately (150 - 250 ohm-m) to strongly corrosive (60 - 150 ohm-m). Soil sample analysis shows liquid limit results that vary from 37.6 to 59.7, while the plasticity limit results vary from 29.3 to 42.5 and all the plasticity index plots were below the A line indicating presence of non-plastic clay. The natural moisture content values vary from 21.4 to 35.5 %. The 2 m depth slice isoresistivity map and clay plasticity factor were synthesized using additive model to generate subsurface CR-index corrosivity model map which indicates that the northwestern, north-eastern and southern parts of the area are moderately (0.4 - 0.6) to strongly corrosive (0.6 - 0.8), while the upper central area and the flanks are slightly corrosive. The moderately and strongly corrosive zones correspond to the low elevation and water logged zones of the study area. The corrosivity model map was validated by the pH and corrosivity data.

Appraisal of Commonly used Mine Planning and Design Software in Ghanaian Surface Mines
Authors: Eshun Peter Arroja , Bediaku G. K. 
Published: April 2021

Mine planning and design software improve productivity at every stage of a mine’s life and simplify mine planning and design processes so that a given deposit can be mined safely and economically. This study was set out to appraise Surpac and MineSight as the commonly used mine planning and design software in most Ghanaian surface mines. Questionnaires were administered to users in seven (7) producing mines using seven (7) appraisal criteria which include: ease of installation/configuration; user friendliness; performance capability; customisation (scripting) capability; compatibility with other software; cost effectiveness; and vendor support. Secondary data from Abosso Goldfields Limited (AGL) was used to plan and design AGL’s Huni pit using the two software to validate responses from the questionnaire administration. This enabled a comparative assessment of the strengths and weaknesses of the two software to be done. Surpac was ranked ahead of MineSight in all the seven (7) appraisal criteria, except for performance capability. The two software during the validation process gave good solid model volume and tonnage estimates but had little differences in the volumes and tonnages of partials. Surpac showed strength in installation and learning, block modelling, and partials extraction and estimation whilst MineSight showed strength in multiple user flexibility, pit design, and solid model creation and estimation. Recommendations to improve the two software have been offered as part of the study and a careful consideration of Datamine is suggested as they are making inroad into the Ghanaian market especially with their underground modules.

Which Pathways Should Indonesia Follow to Achieve Its Energy Development Goals into the Future?
Authors: Hanan Nugroho  
Published: April 2021

Indonesia has developed a plan for its energy sector far into the future, however, the plan might be challenged by several international agreements that the country ratifies. The UN Report suggests several pathways for Indonesia to achieve the SDGs’ goal number 7 (affordable and clean energy). It challenges the current plan for expanding city gas networks, instead, it offers extensive uses of the electric cooking stove. It recommends that Indonesia accelerates its energy conservation efforts and reduce its energy sector’s greenhouse gasses emission by a figure which is higher than the original target. Besides, Indonesia should develop no more new coal-fired power plants and should continue to remove fossil fuel subsidies and encourage the issuance of green financing. This paper supports but also challenges the report by several arguments based on the country’s energy-economy-environment problems.

Authors: Muhammad Fithri Umam  
Published: April 2021

Tulisan ini mencoba menelaah secara kritis sejarah perkembangan tafsir pada era kodifikasi hasil periodisasi Muḥammad Ḥusayn al-Dhahabī dalam karya monumentalnya, al-Tafsīr wa al-Mufassirūn. Al-Dhahabī mengklasifikasi periode kodifikasi tafsir menjadi lima tahap (al-khaṭwah). Menurutnya, kompilasi dan kodifikasi tafsir yang mencakup ayat per-ayat, surat per-surat, dan disusun secara mandiri tidak menumpang dalam bagian bab-bab hadis, juga sistematis sesuai urutan mushaf demikian itu baru dilakukan pada era tābi’ tābi’i al-tabi’īn, seperti Ibnu Mājah (w. 273 H), al-Ṭabarī (w. 310 H), dan ulama setelahnya. Tujuan tulisan ini adalah untuk menguji akurasi periodisasi al-Dhahabī tersebut. Sehingga memakai analisis verikatif-kualitatif yang meliputi verifikasi autentisitas atau keaslian sumber, dan kredibilitas. Ditambah keterangan dari kitab-kitab tārīkh, tarājim, ṭabaqāt, yang banyak mengeksplorasi sejarah masa lalu, menuntut tulisan ini mengkritisi periodisasi yang dipetakan oleh al-Dhahabī.

ABSTRAK
Tulisan ini mengkaji secara eksploratif dan analitis tentang fenomena pengulangan (al-takrâr) yang terdapat di dalam al-Qur`an. Tujuan dari penelitian ini adalah untuk mendeskripsikan secara konseptual tentang adanya fenomena pengulangan di dalam al-Qur`an, meliputi definisi, jenis, serta fungsi dari pengulangan tersebut.
Penelitian ini merupakan jenis penelitian kepustakaan, yaitu penelitian dengan menggunakan studi teks atau pustaka yang pada umumnya lebih memerlukan olahan filosofik dan teoritik dari pada empirik. Pembahasan dalam penelitian ini bersifat deskriptif-analitis, yaitu dengan memaparkan definisi pengulangan (al-takrâr) dalam al-Qur`an, jenis-jenis pengulangan, contoh, serta fungsi dari al-takrâr itu sendiri.
Hasil dari penelitian ini adalah: 1) Secara terminologi dapat disimpulkan bahwa definisi al-takrâr fi al-Qur`ân yaitu pengulangan yang terdapat dalam al-Qur`an (kalâmullâh), baik berupa lafadz, ayat, maupun topik-topik tertentu seperti: kisah para nabi; pembahasan surga dan neraka; kabar gembira dan peringatan, serta pengulangan turunnya ayat ataupun surat, dengan tujuan-tujuan tertentu, yang hal ini merupakan salah satu bentuk i’jâz al-Qur`an, dalam segi gaya bahasa dan kandungan maknanya. 2) Secara umum, fenomena al-takrâr dalam al-Qur`an dibagi menjadi dua jenis, yaitu pengulangan lafadz dan makna (takrâr al-lafdz wa al-ma’nâ) dan pengulangan makna saja, tanpa lafadz (takrâr al-lafdz dûna al-ma’nâ). 3) Fungsi al-takrâr dalam al-Qur`an antara lain adalah li al-taqrîr (penetapan dan penegasan) li al-ta`kîd (menguatkan makna), li al-ta’dhîm (memuliakan), li al-tahwîl (memberikan gambaran buruk dan menakutkan).

NALAR IDEOLOGIS FIQIH DALAM TAFSIR AL-QUR’AN (Telaah Konstruksi Tafsir Pada Masa Abbasiyah)
Authors: Afwadzi Benny 
Published: April 2021

Artikel ini mengkaji tentang nalar ideologis fiqih yang muncul dalam periode dinasti Abbasiyah, yang mengkhususkan pada kitab tafsir dari ulama pengikut madzhab empat, yakni madzhab H̲anafi, Mâliki, Syâfi’i, dan H̲anbali. Ulama H̲anafiyah diwakili oleh al-Jashshâsh, ulama Mâlikiyah diwakili oleh Ibnu al-‘Arabi, ulama Syâfi’iyah diwakili oleh Fakhruddîn al-Râzi, dan ulama Hanâbilah diwakili oleh Ibnu al-Jauzi. Kesimpulan yang diperoleh adalah bahwa penafsiran terhadap ayat-ayat al-Qur’an dalam masing-masing kitab tafsir terlihat membela pemikiran dalam madzhab yang dianut oleh penulisnya. Beberapa sampel yang diambil, yakni diskursus ‘âm dan khâsh, amr dan nahy, serta lafadz musytarak membuktikan bahwa masing-masing ulama madzhab mempertahankan ideologi yang terdapat dalam madzhabnya dalam bidang fiqih, sehingga tafsir hukum yang muncul berwarna dengan warna madzhab si mufassir.

SURAT AL-BAQARAH: REPETISI SEBAGAI PIRANTI KOHESI DALAM AL-QUR’AN
Authors: Ma’arif Samsul 
Published: April 2021

This research is an answer to the notion that the Koran is not systematic and confused book, that has no cohesion in its topics and themes. This research is seeking for the function of repetition as a device of cohesion in the text of the Koran, particularly in surah al-Baqarah. This research is a library research with data sources from the Koran as a text by using a sample surah al-Baqarah (number 2) as it is written in Mushhaf in circulation today. This study departs from the theory of Halliday and Hasan (1976) of Systemic Linguistics by using methods and techniques of qualitative descriptive analysis. This research indicates that the repetition of language units, either repetition of sounds, especially the form of syllables, repetition of words, phrases, clauses, sentences, and or even repetition of topics, creats a ties that can be combined by the text of the surah al-Baqarah. Through repetition in the surah al-Baqarah cohesion or coherence is found in the level of verses of surah, cohesion in topics surah, cohesion surah al-Baqarah, and even the cohesion of the Koran as a whole.Keywords: surah al-Baqarah, the Koran, repetition, cohesion
KRITIK ATAS KRITIK IGNAZ GOLDZIHER TENTANG QIRĀ’ĀT
Authors: Ecky Syahrullah  
Published: April 2021

Goldziher went to great length to impose the Qur'an as scripture by critisizing the Qirā'āt aspect. He argued that the existence of Qirā'āt was an evidence of inconsistency of the Qur'an in its reading variants. Goldziher also revealed that Muslims previously tried to equate the Qirā'āt, but this was not realized because it was hampered by the lack of punctuation system at that time. This article describes and analyzes some of the scholars' criticisms which has criticized Goldziher's opinion. From the analysis, it is found that Goldziher's argument is not supported by strong evidence and data, and tends to ignore historical data.

MODEL PENAFSIRAN KONTEMPORER
Authors: Ahmad Mustofa  
Published: April 2021

Abstrak
Ada dua istilah dalam kajian tafsir al-Qur`an, yaitu mā ḥawla al-Qur`ān dan mā fī al-Qur`ān. Istilah yang pertama merujuk pada pembahasan al-Qur`an dengan titik tekan pada aspek sosio-historis dan antropologis masyarakat Arab pada masa turunnya al-Qur’an. Sedangkan istilah yang kedua merujuk pada upaya penggalian makna sejati dari setiap kata bahkan setiap huruf di dalam al-Qur`an. Jika bentuk kajian kedua ini biasanya berupa karya tafsir, maka bentuk kajian yang pertama lebih banyak berupa prinsip dan metode baru yang digunakan dalam menafsirkan, atau bahkan bisa berupa kritik terhadap model, sistematika dan metode penafsiran klasik. Dalam studi yang sederhana ini, kita akan menggali dan mengeksplorasi pemikiran salah satu sarjana muslim kontemporer terkemuka yang mampu melakukan kajian terhadap kedua wilayah tersebut secara bersamaan, yaitu M. Izzat Darwazat. Lewat kitab al-Tafsīr al-Ḥadīth-nya, M. Izzat Darwazat mempopulerkan sebuah model penyusunan kitab tafsir dengan menggunakan sistematika tartīb al-nuzūl (sesuai urutan turunnya sūrah al-Qur`an) serta mengenalkan metode penafsiran al-Qur`an dengan menggunakan prinsip-prinsip hermeneutika.

Sosialisasi pastoral adalah suatu upaya yang dilakukan agar pelayanan gereja memiliki perkembangan dan masalah yang dihadapi dapat terselesaikan dengan baik berdasarkan Alkitab. Dengan adanya Pengabdian Kepada Masyarakat (PKM) memudahkan untuk penyelesaikan masalah yang telah terjadi, Dalam mewujudkan jemaat yang berpartisipasi dalam pelayanan kembali. Awal berdirinya suatu rumah ibadah yang terletak di Pondok Natai merupakan pemikiran bersama jemaat dan gembala serta dengan tujuan yaitu: “membangun gereja untuk kenyamanan kita bersama dalam beribadah”. Tetapi kenyataan yang ada setelah gereja berdiri kokoh dan dapat digunakan, ada beberapa jemaat yang tidak ibadah dan bahkan ada beberapa keluarga yang pindah agama. Waktu semakin berlalu keadaan jemaat semakin terpuruk dan partisipasi dalam pelayanan sudah berkurang, jemaat yang datang untuk ibadah setiap minggunya hanya satu atau dua orang yang lain memilih sibuk sendiri dan tidak peduli akan ibadah-ibadah yang dilaksanakan. Sosialisai pastoral tentang pemulihan bagi pelayanan di Pondok Natai yang akan dilakukan merupakan suatu upaya agar jemaat dapat ibadah serta berpartisipasi dalam kemajuan pelayanan kembali.
