Tidak Berfungsinya Alat Listrik Dibimbing Oleh MAHFUDDIN ZUHRI&#13;
Kebakaran listrik rumah tangga sering disebabkan panas berlebih pada titik&#13;
sambungan yang tidak terdeteksi proteksi konvensional seperti Miniature Circuit&#13;
Breaker (MCB). Penelitian ini merancang sistem peringatan dini berbasis ESP32&#13;
untuk memantau arus, tegangan, dan Suhu titik sambungan dengan sensor PZELM-&#13;
004T dan SHT31, disertai pemutusan otomatis (relay) dan notifikasi Telegram.&#13;
Pengujian meliputi kalibrasi Sensor terhadap alat ukur standar, waktu respons dan&#13;
keandalan notifikasl pada berbagai sinyal Wi-Fi, serta pengaruh volume&#13;
enkapsulasi terhadap deteksi suhu. Rata-rata error tegangan 2,870/0, arus 7,330/0,&#13;
Suhu 2,020/0. Waktu tunda pemutusan dan notifikasi detlk; notifikasi&#13;
terkirim 17 dari 17 pengujian (15 arus berlebih, 2 Suhu berlebih), termasuk Sinyal&#13;
terlemah (RSSI -79 dBm). Kotak enkapsulasi kecil (f 24 cmS) mencatat Suhu hingga&#13;
23,5 oc lebih tinggi daripada kotak besar (+ 882 cm') pada arus relatif setara. Pada&#13;
beban kontinu, Suhu naik dari 32,2 oc menjadi 58,0 oc dalam 21 menit, dengan arus&#13;
sekitar 5,15-5,26 A sejak menit ke-8.; ASYAHDAN AMRULLAH. Early Warning System for Fire Hazards Caused by&#13;
Electrical Appliance Malfunction. Supervised by MAHFUDDIN ZUHRI.&#13;
Household electrical fires are often caused by overheating at connection&#13;
points that go undetected by conventional protection such as a Miniature Circuit&#13;
Breaker (MCB). This study designs an ESP32-based early warning system to&#13;
monitor current, voltage, and temperature at connection points using PZEM-()04T&#13;
and SHT31 sensors, with automatic relay disconnection and Telegram notifications.&#13;
Testing covered sensor calibration against standard measuring instruments,&#13;
response time and notification reliability under various Wi-Fi signals, and the effect&#13;
of enclosure volume on temperature detection. Average errors were 2.87% for&#13;
voltage, 7.33% for current, and 2.02% for temperature. Power cut-off and&#13;
notification delay was 3.17-5.73 seconds; notifications were delivered in 17 Of 17&#13;
tests (15 overcurrent, 2 overtemperature), including at the weakest signal (RSSI&#13;
79 dBm). The small enclosure (+ 24 cm3) recorded temperatures up to 23.5 oc&#13;
higher than the large enclosure (:E 882 cm') at relatively equal current. Under&#13;
continuous load, temperature rose from 32.2 oc to 58.0 oc in 21 minutes, with&#13;
current Of about 5.15-5.26 A from minute 8.

<summary type="text">PENGARUH VARIASI KEDALAMAN LUBANG RESAPAN  BERBASIS BIOPORI DAN JENIS BAHAN ORGANIK  TERHADAP PERMEABILITAS TANAH
FAHRIZAL, SHANDY PUTRA
Lubang Resapan Biopori (LRB) merupakan teknologi konservasi tanah dan &#13;
air yang berpotensi memengaruhi permeabilitas tanah melalui penambahan bahan &#13;
organik. Penelitian ini bertujuan mengkaji pengaruh penerapan LRB, kedalaman &#13;
lubang, dan jenis bahan organik terhadap permeabilitas tanah serta menentukan &#13;
kombinasi perlakuan dengan permeabilitas tertinggi. Penelitian dilaksanakan di &#13;
petak erosi Kebun Pendidikan Cikabayan, IPB University, menggunakan &#13;
Rancangan Acak Kelompok dengan lima perlakuan dan tiga kelompok yaitu &#13;
kontrol tanpa LRB, LRB berisi serasah jagung, dan LRB berisi sampah sayuran, &#13;
masing-masing LRB dengan kedalaman lubang 50 cm dan 100 cm. Permeabilitas &#13;
diukur dengan metode inverse auger hole, data dianalisis menggunakan analisis &#13;
ragam, uji Tukey taraf 5%, serta analisis korelasi. Perlakuan berpengaruh nyata &#13;
terhadap permeabilitas tanah (p=0,002). LRB berisi sampah sayuran kedalaman 50 &#13;
cm dan 100 cm menghasilkan permeabilitas 2,50 cm/jam dan 2,82 cm/jam (kelas &#13;
sedang), berbeda nyata dengan kontrol (1,09 cm/jam) dan LRB berisi serasah &#13;
jagung kedalaman 50 cm dan 100 cm (1,11 cm/jam dan 1,16 cm/jam; kelas agak &#13;
lambat). Perlakuan LRB berisi serasah jagung tidak berbeda nyata dengan kontrol. &#13;
Perbedaan kedalaman LRB tidak menghasilkan perbedaan permeabilitas yang &#13;
nyata. Permeabilitas tertinggi diperoleh pada LRB berisi sampah sayuran &#13;
kedalaman 100 cm, namun tidak berbeda nyata dengan kedalaman 50 cm. Bobot &#13;
isi, pori total, dan pori drainase tidak berbeda nyata antar perlakuan dan berkorelasi &#13;
lemah dengan permeabilitas, sehingga perbedaan permeabilitas diduga berkaitan &#13;
dengan keterhubungan jalur aliran air di sekitar lubang yang tidak tercermin pada &#13;
sifat fisik tanah di antara lubang. Dengan demikian, sampah sayuran lebih efektif &#13;
dibandingkan serasah jagung dalam meningkatkan permeabilitas tanah pada &#13;
penerapan LRB.; Biopore-Based Infiltration Holes (LRB) are a soil and water conservation &#13;
technology that may influence soil permeability through the addition of organic &#13;
matter. This study aimed to examine the effects of LRB application, hole depth, and &#13;
organic material type on soil permeability, and to determine the treatment &#13;
combination with the highest permeability. The study was conducted in the erosion &#13;
plots of the Cikabayan Teaching Farm, IPB University, using a Randomized &#13;
Complete Block Design with five treatments and three blocks: a control without &#13;
LRB, LRB filled with corn litter, and LRB filled with vegetable waste, with each &#13;
LRB at hole depths of 50 cm and 100 cm. Permeability was measured using the &#13;
inverse auger hole method, and the data were analyzed using analysis of variance, &#13;
Tukey’s test at the 5% level, and correlation analysis. The treatments significantly &#13;
affected soil permeability (p=0.002). LRB filled with vegetable waste at depths of &#13;
50 cm and 100 cm produced permeability of 2.50 cm/hour and 2.82 cm/hour &#13;
(moderate class), significantly different from the control (1.09 cm/hour) and LRB &#13;
filled with corn litter at depths of 50 cm and 100 cm (1.11 cm/hour and 1.16 &#13;
cm/hour; moderately slow class). The corn litter LRB treatments were not &#13;
significantly different from the control. Differences in LRB depth did not produce &#13;
significant differences in permeability. The highest permeability was obtained with &#13;
LRB filled with vegetable waste at a depth of 100 cm, but it was not significantly &#13;
different from the 50 cm depth. Bulk density, total porosity, and drainage porosity &#13;
did not differ significantly among treatments and were weakly correlated with &#13;
permeability. Therefore, differences in permeability are presumed to be related to &#13;
the connectivity of water flow paths around the holes, which is not reflected in the &#13;
physical properties of the soil between the holes. Thus, vegetable waste is more &#13;
effective than corn litter in increasing soil permeability in LRB application.

Fase lepas sapih merupakan masa adaptasi anak domba terhadap pakan padat. Penelitian ini mengevaluasi pengaruh penambahan tepung daun pepaya 10% dalam lamb starter terhadap konsumsi dan performa anak domba lepas sapih. Sebanyak 15 anak domba jantan persilangan Dorper × Garut umur 3–5 bulan diamati menggunakan rancangan acak kelompok dengan tiga perlakuan dan lima ulangan, P0 (tanpa tepung daun pepaya), P1 (tepung daun pepaya 10%), dan P2 (albendazol). Data dianalisis dengan analisis ragam, dilanjutkan uji Tukey bila perlakuan berpengaruh nyata. Konsumsi konsentrat pada P1 (538 g/ekor/hari) lebih tinggi daripada P0 (416 g/ekor/hari) dan P2 (399 g/ekor/hari; p : 0,001). Perlakuan tidak berpengaruh nyata terhadap konsumsi hijauan dan nutrien, pertambahan bobot badan harian, maupun efisiensi pakan (p &gt; 0,05). Tidak terjadi kematian selama penelitian. Penambahan tepung daun pepaya 10% meningkatkan konsumsi konsentrat, tetapi belum meningkatkan pertumbuhan anak domba.
