Abstract

One solution that can be taken to reduce GHG emissions is to reduce consumption of fossil fuels and replace them with renewable energy sources. Indonesia is rich in renewable energy sources, and one that has potential to be developed is solar energy. In line with Indonesia's development into a developed country, energy consumption is increasing. One of the activities that contributes to the largest energy use is cooking. The need for energy for cooking in Indonesia is large because the population and households are very large, No. 4 in the world. Solar Cooker is an alternative to reduce the use of fossil or traditional energy for cooking activities. Previous research has shown how the performance of a Solar Cooker can be improved if it is integrated with PCM thermal energy storage, making it possible to speed up cooking time, cook with low solar intensity and even make it possible to cook at night. However, the quantitative influence of the number of PCMs in a solar cooker has not been specifically explained or studied. A low quantity of PCM results in reduced performance, while a high quantity will increase the thermal load, and thus overheating. This research tested 4 units of Simple Tube type Solar Cooker with different quantities of PCM for each unit. From the results of testing the Solar Cooker with the PCM thermal Energy Storage TEST with variations in PCM volume, it showed performance in storing heat for longer even in conditions of high rainfall day and night conditions. This is shown from all observation results during the 6 days of the experiment. As evidenced by the low ambient air temperature and high humidity, especially at night, the temperature drop in the cooking vessel water is quite low. This applies to every variant. From the experimental results, it can also be seen that variants number 1 and 3, especially number 3, have quite good performance, in absorbing heat and storing heat with an outer diameter of 350 mm

Abstract

Solar radiation varies by region, and photovoltaic (PV) panels typically achieve a maximum efficiency of 21%. This study examines the impact of a dual-axis solar tracker and 5mm reflector glass on the performance of a 100Wp photovoltaic system. The experiment was conducted for three days in September, involved placing reflector glass perpendicular to incoming sunlight to enhance light capture and thermal efficiency. Results showed that the system achieved a maximum efficiency of 19.31% at 10:00 AM on Day 2, with a peak power output of 31.08 W under an irradiance of 595.26 W/m². The lowest efficiency of 4.26% occurred at 8:15 AM on Day 3. The highest recorded temperature was 36.6°C, while the lowest was 30.4°C. The findings suggest that using a dual-axis tracker with reflector glass can improve PV panel efficiency and power generation by optimizing incident radiation and heat distribution

Abstract

AbstractThis research aims to explain the concept and understanding of criminalization against prostitution actors, analyze the history and development of criminalization regulations against prostitution actors in Indonesia, and examine the factors that encourage the need for criminalization against prostitution actors in Indonesia.The research method used is the statutory approach and data collection method using a literature study. In addition, the researcher also conducted in-depth interviews with informants. All of the results obtained will be analyzed using the evaluation technique, namely whether it is appropriate or not, agree or disagree, true or false, valid or invalid by the researcher against a view, proposition, statement, formulation of norms, and decisions, both contained in primary and secondary legal materials. The processed data is analyzed qualitatively juridically by explaining the data results systematically to obtain meaning and conclusions.The research results show that the criminalization of prostitution actors refers to law enforcement actions that impose criminal sanctions on individuals involved in prostitution activities. This can take the form of fines, imprisonment, or even more severe punishments. The history of the regulation shows that the regulation of prostitution in Indonesia has undergone several changes throughout history. However, the regulation still does not regulate prostitution more concretely. In fact, there are many factors that encourage the need for criminalization of prostitution actors, such as religious norms and immoral norms.AbstrakPenelitian ini bertujuan untuk menjelaskan pengertian dan konsep kriminalisasi terhadap pelaku pelacuran, menganalisis sejarah dan perkembangan pengaturan kriminalisasi terhadap pelaku pelacuran di Indonesia, serta mengkaji faktor-faktor yang mendorong perlunya kriminalisasi terhadap pelaku pelacuran di Indonesia. Metode penelitian yang digunakan yaitu menggunakan pendekatan perundang-undangan dan cara pengumpulan data menggunakan studi kepustakaan. Selain itu, peneliti juga melakukan wawancara mendalam dengan para informan. Demikian hasil keseluruhan yang didapatkan akan dianalisis data menggunakan teknik evaluasi yaitu tepat atau tidak tepat, setuju atau tidak setuju, benar atau salah, sah atau tidak sah oleh peneliti terhadap suatu pandangan, proposisi, pernyataan rumusan norma, keputusan, baik yang tertera dalam bahan primer maupun dalam bahan hukum sekunder. Data yang telah diolah dianalisis secara yuridis kualitatif dengan menjelaskan hasil data secara sistematis sehingga dapat memperoleh arti dan kesimpulan. Adapun hasil penelitian menunjukkan bahwa kriminalisasi terhadap pelaku pelacuran mengacu pada tindakan penegakan hukum yang menjatuhkan sanksi pidana kepada individu yang terlibat dalam kegiatan pelacuran. Hal ini dapat berupa denda, kurungan penjara, atau bahkan hukuman yang lebih berat. Sejarah pengaturan menunjukkan bahwa pengaturan mengenai pelacuran di Indonesia telah mengalami beberapa kali perubahan sepanjang sejarah. Namun, tetap saja pengaturan tersebut tidak mengatur pelacuran secara lebih konkret. Padahal, banyak faktor-faktor yang mendorong perlunya kriminalisasi pelaku pelacuran seperti norma agama dan norma asusila.

Abstract

Abstract  One form of law enforcement is the imposition of punishment on the defendant which is reflected in the judge's decision. Especially in the trial of corruption crimes since Law Number 31 of 1999 concerning the Eradication of Corruption Crimes was enacted, most corruption defendants are required to use Article 2 and Article 3 of the Corruption Law concerning acts of enriching/benefiting oneself or another person or a corporation that can detrimental to state finances. The decision of the Corruption Court against the Defendants who violated Articles 2 and 3 of the Corruption Eradication Law, there is a very striking disparity. To overcome this disparity, the Supreme Court of the Republic of Indonesia has issued Perma Number 1 of 2020 concerning Guidelines for the Criminalization of Article 2 and Article 3 of the Corruption Eradication Law which was promulgated in the State Gazette on July 24, 2020. The panel of judges who tried case Number 25/Pid.Sus-TPK/2021/PN.Ptk only considered Perma Number 1 of  2020 as a guideline, not seeing the Perma as a procedural law whose existence is a product of legislation that fills legal voids and shortcomings and bind the judge's freedom in imposing a sentence even though the meaning of the judge's freedom is to be free to make decisions without any intervention from internal and external parties and judges in deciding cases are still guided by the applicable laws, so that the freedom of judges is not absolute freedom but must be responsible. Because Perma Number 1 of 2020 is a product of legislation that fills legal voids and deficiencies, the judge in imposing a criminal offense under Article 2 and Article 3 of the Law on the Eradication of Criminal Acts of Corruption is obliged to follow the Regulation of the Minister of Justice Number 1 of 2020 as a procedural law and needs to be There are strict sanctions from the institutional leadership of the Supreme Court of the Republic of Indonesia against judges who impose criminal penalties on Article 2 and Articles of the Law on the Eradication of Criminal Acts of Corruption, which do not comply with the Perma.  Abstrak  Salah satu bentuk penegakan hukum adalah penjatuhan hukuman kepada terdakwa yang tercermin dalam putusan hakim.   Khusus dalam persidangan tindak pidana korupsi sejak Undang-Undang Nomor 31 Tahun 1999 Tentang Pemberantasan Tindak Pidana Korupsi diberlakukan, kebanyakan terdakwa korupsi dituntut menggunakan Pasal 2 dan Pasal 3 Undang-Undang Tipikor tentang perbuatan memperkaya/menguntungkan diri sendiri atau orang lain atau suatu korporasi yang dapat merugikan keuangan negara.   Putusan Pengadilan Tindak Pidana Korupsi terhadap Terdakwa yang melanggar Pasal 2 dan Pasal 3 UU Pemberantasan Tindak Pidana Korupsi, terdapat disparitas yang sangat mencolok. Untuk mengatasi adanya disparitas tersebut Mahkamah Agung Republik Indonesia telah mengeluarkan Perma Nomor 1 Tahun 2020 Tentang   Pedoman Pemidanaan Pasal 2 Dan   Pasal 3 Undang-Undang Pemberantasan Tindak Pidana Korupsi yang telah diundangkan dalam Lembaran Negara pada tanggal   24 Juli 2020. Majelis hakim yang mengadili perkara Nomor 25/Pid.Sus-TPK/2021/PN.Ptk hanya menganggap Perma Nomor 1 Tahun 2020 sebagai pedoman saja bukan melihat Perma tersebut sebagai hukum acara yang keberadaannya merupakan produk perundang-undangan yang mengisi kekosongan dan kekurangan hukum dan mengikat kebebasan hakim dalam menjatuhkan pemidanaan padahal arti kebebasan hakim tersebut adalah bebas menjatuhkan putusan tanpa ada intervensi dari pihak internal dan eksternal dan hakim dalam memutus perkara tetaplah berpedoman kepada perundang-undangan yang berlaku, sehingga kebebasan hakim bukanlah kebebasan yang mutlak melainkan harus bertanggungjawab.   Oleh karena Perma Nomor 1 Tahun 2020 yang keberadaannya merupakan produk perundang-undangan yang mengisi kekosongan dan kekurangan hukum, maka hakim dalam menjatuhkan pidana Pasal 2 dan Pasal 3 Undang-Undang Pemberantasan Tindak Pidana Korupsi wajib mempedomani Perma Nomor 1 Tahun 2020 sebagai hukum acara dan perlu ada sanksi tegas dari pimpinan institusi Mahkamah Agung Republik Indonesia terhadap hakim yang menjatuhkan pidana Pasal 2 dan Pasal Undang-Undang   Pemberantasan Tindak Pidana Korupsi yang tidak mempedomani Perma tersebut.

Abstract

AbstractChildren are an integral part in the continuation of the life of the nation and state because children are a valuable asset owned by a nation as the next generation or the future face of the Indonesian nation in the future. Therefore, children are always the center of attention and must be supervised and receive special protection in the growth period. Indonesia has provided special protection guarantees, such as by establishing Law Number 35 of 2014 concerning Amendments to Law No. 23 of 2002 concerning Child Protection. But in this modern era, with technological sophistication and no age limit requirements for using an Android cellphone, it makes access to public information so easy that children can easily find out and get various kinds of information, especially regarding the ratification of the Omnibus Law. Work that is considered controversial by society. So demonstrations of rejection took place in various parts of Indonesia, one of which was in Pontianak City, West Kalimantan. The participation of children in political activities in Pontianak City is the center of attention and questions for government and community circles, because children in their growth and development period are prohibited and are not allowed to be involved in political activities so this is very unfortunate to happen. Based on the data and facts that the author obtained through the West Kalimantan Regional Child Monitoring and Protection Commission (KPPAD KALBAR) it was recorded that there were 20 (Twenty Children) through the Pontianak City POLRESTA RESKRIM SAT it was recorded that there were 169 (One Hundred Sixty Nine) children participating in political activities within a period of 3 (three) days of demonstrations against the Omnibus Law on Job Creation in Pontianak City. This research uses empirical research methods The results of the author's research in this thesis research are to find facts about the causal factors and how legal protection is given to children who take part in demonstrations of the Omnibus Law on Job Creation in Pontianak City. The factors causing children to take part in the demonstration are the bandwagon factor and the legal protection given to children involved in the demonstration is by informing the parents and/or guardians besides that the children are secured by West Kalimantan KPPAD and the Police to be protected and educated so they don't return to these demonstrations.AbstrakAnak merupakan bagian yang tak terpisahkan dalam kelangsungan kehidupan berbangsa dan bernegara karena anak merupakan aset berharga yang dimiliki suatu bangsa sebagai generasi penerus atau wajah masa depan bangsa Indonesia di masa mendatang oleh karena itu, anak selalu menjadi pusat perhatian dan harus diawasi serta mendapatkan perlindungan khusus dalam masa tumbuh kembangnya. Indonesia telah memberikan jaminan perlindungan secara khusus, seperti dengan membentuk Undang-Undang Nomor 35 Tahun 2014 Tentang Perubahan Atas Undang-Undang No. 23 Tahun 2002 Tentang Perlindungan Anak. Tetapi Pada zaman modern ini, dengan kecanggihan teknologi dan tidak adanya syarat batasan usia dalam menggunakan handphone android menyebabkan begitu mudahnya akses-akses dalam memperoleh informasi publik sehingga anak pun dapat dengan mudah mengetahui dan mendapatkan berbagai macam informasi khususnya terkait pengesahan Undang-Undang Omnibus Law Cipta Kerja yang dianggap kontroversial oleh masyarakat. Sehingga aksi unjuk rasa penolakan terjadi di berbagai wilayah Indonesia salah satunya di Kota Pontianak Kalimantan Barat. Turut ikut sertanya anak dalam kegiatan politik di Kota Pontianak menjadi pusat perhatian dan pertanyaan bagi kalangan pemerintahan dan masyarakat, karena anak dalam masa tumbuh kembangnya dilarang dan tidak diperkenankan untuk terlibat dalam kegiatan politik sehingga hal ini sangatlah disayangkan terjadi. Berdasarkan data dan fakta yang penulis peroleh melalui Komisi Pengawasan dan Perlindungan Anak Daerah Kalimantan Barat (KPPAD KALBAR) tercatat ada 20 (Dua Puluh Anak) melalui SAT RESKRIM POLRESTA Kota Pontianak tercatat ada 169 (Seratus Enam Puluh Sembilan) anak yang ikut serta dalam kegiatan politik tersebut dalam jangka waktu 3 (Tiga) hari aksi demo Undang-Undang Omnibus Law Cipta Kerja di Kota Pontianak. Penelitian ini menggunakan metode penelitian empiris. Hasil penelitian penulis dalam penelitian   ini adalah untuk menemukan fakta mengenai faktor penyebab dan bagaimana perlindungan hukum yang diberikan kepada anak yang ikut serta dalam aksi unjuk rasa Rancangan Undang-Undang Omnibus Law Cipta Kerja Di Kota Pontianak. Adapun faktor penyebab anak ikut serta dalam aksi unjuk rasa tersebut adalah faktor ikut-ikutan dan perlindungan hukum yang diberikan bagi anak-anak yang terlibat dalam aksi unjuk rasa tersebut adalah dengan memberitahukan kepada pihak orangtua dan/atau wali selain itu anak-anak tersebut diamankan oleh pihak KPPAD Kalbar beserta Pihak Kepolisian untuk dilindungi dan diedukasi agar tidak kembali melakukan aksi unjuk rasa tersebut.

Abstract

As the tropical country, Indonesia has a sustainable solar energy for the farm products such as coffee. Indonesia’s coffee has been categorized as one of the biggest export products in the world and needs a development system to provide drying coffee beans with good quality. Therefore, this study comprehensively explains an experiment to develop a continuous solar air dryer with a hybrid system for drying coffee. The system has two different modes: off-sunny and sunshine hours. The heated air from the collector is driven into the drying chamber during the sunlight. The results show that the drying chamber's maximum temperature during daylight ranged from 40°C to 56°C and 9°C to 22°C warmer than the ideal environment temperature. Then, the coffee beans got the 12,7% moisture content in 107 hours in a solar dryer with solid dehumidification material. During off-sunlight, the air humidity reaches a 17% reduction and relatively consistent with air temperature. Furthermore, the benefit of this research can support the agricultural system without sunlight and apply a molecular sieve as a solar dehumidifier for the desiccant material in the drying chamber.

Abstract

This study reviews the performance and emissions of compression ignition (CI) engines using Calophyllum inophyllum (CIME/tamanu)-based biofuel additives through a narrative review of the latest international literature. Inclusion criteria encompassed CI engine test studies reporting efficiency metrics (BTE, BSFC) and key emissions (CO, HC, NOx, smoke/PM) for CIME blends (B10–B100) both without and with additive/mitigation strategies. In general, compared to diesel, CIME reduced CO, HC, and smoke/PM, with a trade-off increase in NOx. The addition of oxygenated additives (e.g., n-pentanol, dimethyl carbonate) and ignition improvers (e.g., DTBP) tends to improve combustion quality, reduce BSFC, and suppress CO/HC; while the application of approximately 10% EGR effectively reduces NOx with a moderate penalty on HC/CO/smoke. Nano-additives (graphene/MWCNT) show potential for increasing BTE and reducing smoke, but present issues of dispersion stability and safety/environment. The most balanced performance generally occurs at low–medium blends (≈B10–B20) combined with oxygenated additives and EGR-based NOx control, accompanied by proper injection calibration. From a sustainability perspective, C. inophyllum—as a non-food source with high FFA pretreatment requirements—has the potential to support transportation decarbonization, although industrial-scale success depends on supply chains, policies, and LCA/TEA results. Further studies are recommended on real-world test cycles, long-term durability, aftertreatment compatibility, and comprehensive environmental assessment.

Abstract

Sebagian besar masyarakat Desa Amborgang, Kabupaten Toba, bergantung pada sektor pertanian, selain bekerja sebagai nelayan dan pedagang. Produksi padi mencapai 479,80 ton per tahun dari luas persawahan 81,89 hektare, namun sekam padi yang dihasilkan belum dimanfaatkan secara optimal dan masih dianggap sebagai limbah. Selain itu, keterbatasan akses terhadap mesin penggiling padi karena lokasinya relatif jauh dari ibu kota kecamatan menyebabkan masyarakat membutuhkan waktu cukup lama untuk mengolah padi menjadi beras. Melalui kegiatan Pengabdian kepada Masyarakat, Tim Fakultas Teknik dan FISIPOL UHN memberikan penyuluhan kepada kelompok tani mengenai pemanfaatan sekam padi menjadi produk yang bernilai guna, seperti bahan pengusir bekicot, pengusir tikus, dan kompos. Tim juga memberikan bantuan mesin penggiling padi berkapasitas 10 kg/menit kepada kelompok tani melalui anggota DPRD Kabupaten Toba. Masyarakat mengapresiasi bantuan tersebut karena dapat mempercepat proses pengolahan padi sekaligus menghemat waktu yang dapat dialokasikan untuk kegiatan produktif lainnya. Pemanfaatan sekam sebagai bahan kompos juga diharapkan dapat meningkatkan kualitas dan produktivitas pertanian, mengurangi pencemaran lingkungan, memperbaiki kualitas lahan secara berkelanjutan, serta mengurangi ketergantungan masyarakat terhadap pupuk yang relatif mahal. Dengan demikian, kegiatan ini memberikan manfaat nyata dalam meningkatkan efisiensi pengolahan hasil pertanian sekaligus mendorong pemanfaatan limbah pertanian menjadi produk yang lebih bermanfaat bagi masyarakat Desa Amborgang

Abstract

Penanganan pasca panen komoditi kopi harus betul betul dikelola secara baik agar petani tidak mengalami kerugian akibat terjadinya kerusakan buah. Proses pengeringan kopi setelah selesai di panen khusus varietas Arabicha yang ada di Desa Parbaba Dolok kecamatan Pangururan selama ini tidak ada masalah yang berkaitan dengan produk yang tiba tiba melimpah. Namun 2 tahun belakangan ini Kopi milik Pardosir terkendala pada bagiaan pengeringan yang tidak lagi sesuai hasil yang dikaeringkan dengan permintaan konsumen dengan kata lain kopi yang sudah dikeringkan hingga mencapai kadar air 12% mengalami produk yang menurun. Proses pengeringan yang dilakukan selama ini ada dua metode yang pertama dengan pengeringan langsung di bawah terik matahari dan pengeringan menggunakan alat rumah kaca (Green House). Penegringan dengan rumah kaca memperpendek waktu penegringan dibanding penegringan langsung disamping lebih bersih dan suhu bisa terkontrol.Alat penegring rumah kaca yang ada terbuat dari kayu sebagai rangkan dan penyangga sehingga tidak tahan lama. Bahan penutup dari atas rumah kaca terbuat dari plastic biasa sehingga tidak bertahan lama ketrika diterpa hujan deras serta angin kencang. Teknologi penegring rumah kaca ini selai bahan yang bagus juga dipengaruhi jarak penjemuran (permukaan rak) ke plastic penutup rumah kaca. Kondisi yang ada dilapangan jarak  dari rak ke plastic penutup  kira 30-40cm dan lebar 115cm, rangka penahan plastic penutup terbuat dari bamboo. Perawatan yang dilaksanakan dalam kegiatan ini adalah perbaikan rumah kaca dan dimensi rumah kaca yang cocok dengan kapasitas yang sesuai, serta pelaksanaan edukasi yang memenuhi standar tentang perawatan dan pemilihan material yang cocok dan tahan lama.
